CNC BUSBAR Mechanical transmission couplings, you must know these!

First, the transmission system structure design

1. Avoid the motion uncertainty of the four-bar mechanism of the hinge processing machine hinge

2. Pay attention to the dead point of the organization

3. Avoid the lateral thrust of the guide rail

4. The limit switch should be placed on the component with large stroke in the link mechanism.

5. Pay attention to the transmission angle should not be too small

6. Swinging follower cylindrical cam should not be too short

7. Correctly arrange the offset follower disc cam to move the guide rail position of the follower

8. Balance of plane link mechanism

9. Design intermittent motion mechanism should consider the motion coefficient

10. Using the instantaneous stop section to analyze the reliability of the locking device

11. Select the gear drive type, first consider the use of cylindrical gears

12. When the mechanical requirements are reversed, the motor reversal can generally be considered.

13. Must consider the starting performance of the prime mover

14. Friction transmission should not be used in the crane structure of the crane

15. For mechanisms that require slow movement, the spiral is better than the rack

16. Replace the bulk transmission with a standard gearbox with a large gear ratio

17. Replace the prime mover and transmission with a geared motor

18. Use shaft mounted reducer


Second, the coupling clutch structure design

1. Reasonable choice of coupling type

2. Coupling balance

3. Couplings with sliding friction should pay attention to maintain good lubrication conditions.

4. The high-speed rotating coupling can not have protruding protrusions

5. Use a coupling with shoulder and groove alignment, taking into account the disassembly and assembly of the shaft

6. When the transmission parts of the shaft are required to rotate synchronously, it is not advisable to use a flexible coupling with elastic elements.

7. When the intermediate shaft has no bearing support, do not use the cross slide coupling at both ends.

8. Single universal coupling can not achieve synchronous rotation between two axes

9. Do not use the outer casing of the gear coupling as the brake wheel

10. Pay attention to the lubrication of the gear coupling

11. Notes on nylon rope coupling

12. Precautions for the shear pin type safety clutch

13. Do not use oil-lubricated friction disc clutch for quick separation.

14. It is not advisable to use multi-disc friction clutch when working at high temperature.

15. The clutch operating ring should be mounted on the half clutch associated with the driven shaft.
