皮带失效（Belt failure）.docVIP

皮带失效（Belt failure） Belt fracture 1. overload; 1. check the design; choose the correct width of the belt; 2. driven wheel inertia is too large; 2. choose the right pulley; 3. belt pulley diameter is too small; 3. redesign the number of gearing teeth; 4. too much pretension; 4. adjust the proper preload; 5. belt twisting, bad operation; 5. storage, transportation, installation, careful operation; 6. excessive impact loading; 6. prevent accidental failure and change design; 7. belt up the retaining ring; 7. adjust the parallelism of the axle and check the retaining ring; 8. debris or foreign objects fall into the drive. 8. clean the dirt and check the protective barrier. Excessive wear of belt edges 1. pulleys are not parallel; 1. adjust parallelism; 2., the stiffness of bearing parts is not enough; 2. increase stiffness, indeed fixed; 3. retaining ring bending; 3., amend or replace the retaining ring; 4. the surface of the retainer is rough; 4., amend or replace the retaining ring; A protective shield or holder for a belt transmission device 5. 5. check protective bezel or support. TR class=font-NO1 TD rowSpan=73. excessive wear of belt teeth 1. overload; 1. check the design and choose the correct belt width; 2. too much pretension; 2. adjust the proper preload; 3. rough surface of gear tooth; 3. check and adjust surface roughness; 4. belt pulley radial runout; 4. check and adjust the radial circle runout; 5. dust or sand; 5. avoid sundries; 6. severe vibration; 6. adjust the structure or use the damping device; 7. excessive dirt falling into the gear. 7. clean up dirt. Belt shearing 1. overload or excessive impact load; 1. inspection design; 2., the number of meshing teeth is less than 6 teeth, or the number of teeth of the belt is the number of multiples of the number of teeth; 2. check the design so that the number of belt teeth odd; 3. preload too small; 3. adjust pretightening force; 4. belt pulley diameter is too small; 4. increase pulley diameter; 5. environmen
