Select the material on the shaft and determine the allowable stress Because the reducer is a general machine, there is no special requirement, so 40Cr (quenched and tempered) is selected, the hardness is 280HBS, check the table15-1,take σb=735MPa, σ-1b=60MPa 2. The minimum diameter of the shaft estimated according to the initial torsion strength Check table 15-3, take A0=112,so Shaft ends have 1 keyway, therefore, the axle diameter should be increased by 5% According to the table, the diameter of the standard axle hole is 22mm, so d=22 Figure 7-1 Schematic diagram of high-speed shaft (1) The minimum diameter of the input shaft is obviously d12, where the coupling is mounted. In order to adapt the selected shaft diameter d12 to the coupling aperture, the type of coupling should be selected. The calculated torque of the coupling Tca = KA×T, according to the table, thinking about the stability, we choose KA = 1.3, then: According to the condition that the torque Tca of the coupling should be less than the nominal torque of the coupling, refer to standard GB t4323-2002 or design manual, choose LX3 type coupling. The aperture of the semi-coupling is 22mm, the hub hole length of the semi-coupling and the shaft is 52mm. Choose ordinary flat keys,A type keys, b×h = 6×6mm(GB T 1096-2003), bond length L=40mm。 (2) Initial selection of rolling bearing. Since the bearing is subject to both radial and axial forces, angular contact bearing is selected. Referring to the work requirements and according to d23 = 27mm, select 7206AC angular contact bearing from bearing product catalog, its size: d×D×B = 30×62×16mm, so d34 = d78 = 30 mm. The positioning shaft shoulder height of 7206AC type bearing is found in the manual, h = 3 mm,then choose d45 = d67 = 36 mm. (3)Because the diameter of the gear is small, in order to ensure the strength of the gear wheel body, the gear and the shaft should be made into one and become the gear shaft. So l56 = 55 mm, d56 = 53.134 mm. (4) Thickness of bearing end covere=10, thickness of the gasketΔt=2. According to the bearing end cover for easy assembly and disassembly, ensure that the outer end face of the bearing end cover has a certain distance from the end face of the coupling, K=24; Screw C1=22mm, C2=20mm, thickness of box seat wall δ=8mm, then: (5) Take small spacing distance of enclosure wall Δ1 = 10 mm, the distance between high speed main gear and low speed pinion Δ3 = 15 mm distance. Considering about the housing casting error, when determining the position of rolling bearing, a distance Δ from inner wall of box should be taken, take Δ = 10 mm, the width of low speed pinion b3=85mm, then: At this point, the diameter and length of each section of the shaft have been preliminarily determined.

Stress analysis of the shaft The circumferential force on a high speed pinion Ft1 (d1 is the diameter of the indexing circle of the high-speed pinion) Radial force on a high speed pinion Fr1 Axial force on a high speed pinion Fa1 According to 7206AC angular contact manual, pressure center a=18.7mm Distance between the center point of the first shaft and the bearing pressure center l1: Distance from bearing pressure center to gear fulcrum l2: Distance between gear midpoint and bearing pressure center l3: (1) Calculate the supporting reaction of the shaft Horizontal support reaction: Vertical support reaction: (2) Calculate the bending moment of the shaft, and draw the bending moment diagram The horizontal bending moment at section C: The vertical bending moment at section C: Bending moment diagram of horizontal plane (fig.b) and vertical plane (fig.c). The resultant bending moment at section C: (3) Make composite bending moment diagram (figure d) Make torque diagram (figure e) Figure 7-2 High - speed shaft force and bending moment diagram 4. Check the strength of the shaft Because the bending moment on the left side of C is large and the action has torque, the left side of C is the dangerous section. The bending section coefficient W: The torsion cross section coefficient WT: The maximum bending stress: The shear stress: Check and calculate according to the strength of bending and torsion. For the shaft of one-way drive, torque is processed according to pulsating cycle. Therefore, the reduced coefficient is adopted α=0.6, then the equivalent stress is (10) Check the table, get 40Cr(tempering and tempering) treatment, and the limit of tensile strength σB=735MPa; Then the allowable bending stress of the axis [σ-1b]=60MPa, σca<[σ-1b], so the strength is good. 7.2 Calculation of jack shaft design 1. Select the material on the shaft, and determine the allowable stress Because the reducer is a general machine, there is no special requirements, so choose 45 (quenched and tempered), the hardness: 240HBS. Referring table 15-1, take σb=640MPa, σ-1b=60MPa 2. According to the initial torsion strength, the minimum diameter of the shaft estimated Refer to table 15-3, take A0=112, then: Since the minimum diameter of the shaft section is all rolling bearings, the standard diameter d=35mm is selected. Figure 7-3 Diagram of intermediate shaft (1) Initial selection of rolling bearing. The minimum diameters of the intermediate shaft are d12 and d56 for mounting the rolling bearing. Because the bearing is subject to both radial and axial forces, angular contact bearing is chosen. Referring to the requirement of working and according to dmin = 31.08 mm, from the bearing catalogue, selsct angular contact bearing 7207AC, its size: d×D×B = 35×72×17mm, so d12 = d56 = 35 mm. (2) At the installation of the big gear, take the diameter of the shaft section d45 = 38mm; Positioning by oil baffle ring is taken between the right end of the gear and the right bearing. It is known that the width of the hub of the high-speed large gear wheel b2 = 50mm, in order to press gears reliably, this section should be slightly shorter than the width of the hub, then take l45 = 48 mm. Shaft shoulder positioning is adopted in the left end of the gear, the height of shaft shoulder h = (2~3)R. Refer to the table with trunnion d45 = 38 mm, take h = 5 mm, then the diameter of Collar point d34 = 48 mm. Collar width b≥1.4h, take l34 = 15 mm. (3) Left end rolling bearing adopts oil baffle ring for axial positioning. (4) Considering about material and machining economy, low speed pinion and shaft should be designed and manufactured separately. It is known that the hub width of the low-speed pinion is b3= 85mm, in order to make the end face of oil retaining ring press the gear reliably, this section should be slightly shorter than the width of the hub, so take l23 = 83 mm,d23=38mm。 (5) Take the distance between the low-speed pinion and the inner wall of the boxΔ1 =10 mm, the distance between the high speed big gear and the inner wall of the box Δ2 =12.5 mm, the distance between high speed main gear and low speed pinionΔ3=15mm. Consider housing casting error, when determining the position of rolling bearing, should be from a distance Δ casing wall, take Δ = 10 mm, then: At this point, the diameter and length of each section of the shaft have been preliminarily determined.

Check the strength of the shaft Because the bending moment on the left side of B is large and the action has torque, the left side of B is the dangerous section. Its bending section coefficient: Its torsion cross section coefficient: The maximum bending stress: Its shear stress: Check and calculate according to the strength of bending and torsion. For the shaft of one-way drive, torque is processed according to pulsating cycle. Therefore, the reduced coefficient is adopted α=0.6, then the equivalent stress is Check the table, get 40Cr(tempering and tempering) treatment, and the limit of tensile strength σB=640MPa; Then the allowable bending stress of the axis [σ-1b]=60MPa, σca<[σ-1b], so the strength is good. 7.3 Calculation of low speed shaft 1. Select the material on the shaft, and determine the allowable stress Because the reducer is a general machine, there is no special requirements, so choose 45 (quenched and tempered), the hardness: 240HBS. Referring table 15-1, take σb=640MPa, σ-1b=60MPa 2. According to the initial torsion strength, the minimum diameter of the shaft estimated Refer to table 15-3, take A0=112, then: Shaft end has 1 keyway, so increase shaft diameter by 7% According to the table, the diameter of the standard axle hole is 50mm, so d=50 Figure 7-5 Schematic diagram of low-speed shaft (1) The minimum diameter of the output shaft is obviously the diameter d1 of the shaft where the coupling is mounted. In order to make the selected shaft diameter d1 match the coupling aperture, it is necessary to select the type of coupling.The calculated torque of the coupling Tca = KA×T, refer to the table, consider about stability, then take KA = 1.3,thus: According to the condition that the torque Tca of the coupling should be less than the nominal torque of the coupling, check the standard GB t4323-2002 or the design manual, choose LX4 type coupling. The aperture of the semi-coupling is 50mm, the hub hole length of fitness of the semi-coupling and the shaft is 112mm. Choose ordinary flat bond, A type bond, b×h = 14×9mm(GB T 1096-2003), length of bond L=100mm. (2) Initial selection of rolling bearing. Because the bearing is subject to both radial and axial forces, angular contact bearing is chosen. According to work requirements and d23 = 55mm, angular contact bearing 7212AC is selected from the bearing product catalog, its size: d×D×B = 60×110×22mm, so d34 = d78 = 60 mm. Positioning of bearing oil retaining ring. According to the manual, the positioning shaft shoulder height of type 7212AC bearing is h = 4.5mm, so d45 = 69mm (3) Take the diameter of the shaft section where the gear is mounted d67 = 63 mm;The width of the low-speed large gear hub is known as b4 = 80 mm,in order to make the end face of the oil retaining ring press the gear reliably, this shaft segment should be slightly shorter than the width of the hub, so l67 = 78mm. The left end of the gear is fixed by the shaft shoulder. The height of shaft shoulder h = (2~3)R,The diameter of the shaft d67 = 63 mm, so take h = 10 mm, then the diameter at the collar d56 = 83 mm, take l56=10mm. (4) Thickness of bearing end cover e=10, the thickness of the gasket Δt=2. According to the ease of mounting and dismounting of the bearing end cover, ensure that the outer end face of the bearing end cover has a certain distance from the end face of the coupling K=24, screw C1=22mm, C2=20mm, box seat wall thickness δ=8mm, then: (5) Assume the distance between low level main gear and inner box wall Δ 2 = 12.5 mm, the distance between high speed main gear and low speed pinion Δ 3 = 15 mm distance. Consider housing casting error, when determining the position of rolling bearing, should be from a distance Δ casing wall, assume Δ = 10 mm, then: At this point, the diameter and length of each section of the shaft have been preliminarily determined.

Check the strength of the shaft Because the bending moment on the left side of C is large and the action has torque, the left side of C is the dangerous section Its bending section coefficient: Its torsion cross section coefficient: The maximum bending stress: Its shear stress: Check and calculate according to the strength of bending and torsion. For the shaft of one-way drive, torque is processed according to pulsating cycle. So the reduced coefficient =0.6, then the equivalent stress: Refer to the the table, get 45(tempering) treatment, tensile strength limitσB=640MPa,then the allowable bending stress of the axis[σ-1b]=60MPa, σca<[σ-1b], so the strength is good.

Chapter 11 Seal and lubricate the reducer 11.1 Selection of sealing In order to prevent the leakage of lubricant inside the box and the entry of external impurities into the box to affect the work of the box, between the parts that make up the box, such like the box cover and the box seat, the output of the overhanging shaft, the input shaft and the bearing cover, different types of sealing devices are required. For the joint surface without relative motion, commonly used sealant, oil resistant rubber gasket, etc. For the sealing of rotating parts such as overhanging shaft, different seals and structures should be considered according to their different motion speed and sealing requirements. In this design, because the relative speed of sealing interface is small, contact seal is adopted. The velocity between the input shaft and the bearing cover is V <3m/s, the velocity between the output shaft and the bearing cover is also V 1.2δ 12mm Distance between gear face and inner box wall △2 >δ 12.5mm Case cover and seat rib thickness m1、m m1≈0.85×δ1、m≈0.85×δ 8mm、8mm Outer diameter of high speed bearing end cap D1 D+(5~5.5)d3;D--bearing outer diameter 102mm Outer diameter of end cover of jack bearing D2 D+(5~5.5)d3;D--bearing outer diameter 112mm Outer diameter of low speed bearing end cap D3 D+(5~5.5)d3;D--bearing outer diameter 150mm Chapter 14 Drawing of structure analysis of reduce 14.1 Drawing of assembly 14.2 Housing 14.3 Drawing of gears High speed main gear Low speed pinion 14.4 Drawing of shafts High speed shaft Jack speed shaft Low speed shaft Chapter 15 Conclusion 15.1 Summary After hard work, I finally finished the mechanical design course. In the process of this operation, I encountered many difficulties. The repeated calculation and the design scheme modification exposed my lack of knowledge and experience in this aspect in the early stage, and I learned the lesson of blind calculation. As for drawing assembly drawing and part drawing, due to sufficient preliminary calculation, the whole process took less than three days. During this period, I also received a lot of help from my classmates and teachers. Here I would like to express my most sincere thanks to them. Although the time of this assignment is long and the process is tortuous, for me, the biggest gain is the method and ability. The ability to analyze and solve problems. In the whole process, I found that what students like us most lack is experience, no perceptual knowledge, empty theoretical knowledge, and some things may be out of touch with the reality. In general, I think doing this type of homework is of great help to us. It requires us to systematically connect the relevant knowledge we have learned, expose our shortcomings and make improvements. Sometimes a person's power is limited, the wisdom of all people, I believe our work will be more perfect! Due to the limited time, there are many shortcomings in this design, such as the huge box structure and large weight. The gear calculation is not accurate enough and other defects, I believe, through this practice, I can avoid a lot of unnecessary work in the future design, have the ability to design a more compact structure, transmission more stable and accurate equipment. 15.2 Job description of team members Team leader: 陈旭颖 Finish the designation and calculation of transmission device, motor, dynamic parameters, rolling bearings, keys and couplings.
