The determination of the number of gear pairs and the selection of the distribution principle of the transmission ratio of each level

The determination of the number of gear pairs and the selection of the distribution principle of the transmission ratios of each level are for reference and understanding. For unclear places or related product processing requirements, you can consult EP for free.

1. For the servo deceleration transmission chain that requires stable motion, frequent start and stop and good dynamic performance, it can be designed according to the principle of minimum equivalent transmission inertia and minimum output shaft angle error.For load changesgearFor the transmission device, it is best to use an irreducible ratio for each transmission ratio to avoid simultaneous meshing.

2. For the speed reduction gear transmission chain that mainly improves the transmission accuracy and reduces the return error, it can be designed according to the principle of the minimum error of the output shaft angle.If it is a speed-increasing transmission chain, the speed should be increased in the first few stages.

3. For gear transmission chains with large transmission ratios, fixed-axis gear trains and planetary gear trains can be used in combination.

4. For the speed reduction drive chain that requires the lightest weight possible, it can be designed according to the lightest weight principle.
