Difference, the flexibility being otherwise driven will be affected.For example adjusted using eccentric shaft between pinion gear using gear wheel
The heart away from structure type.The major defect of rigid adjusting method is: 1, can only partially remove backlash, that is, the gap that disappears is incomplete；1, it replaces
Careful adjustment is needed when gear, i.e. installation is inconvenient；3, the processing cost of gear is high.
It is by a gear point in the gear pair in transmission scheme with the method for adding the split gear of spring to eliminate running clearance
Two plate gears are cleaved into, eliminate positive and negative rotation bring gash spacing error in transmission between two plate gears with spring.This kind disappears gap method
Disadvantage is: 1, needing to increase a plate gear, drive mechanism can be made to become complicated, cost improves；2, spring is required to have enough
Rigidity, rigidity is small, cannot reach disappear completely gap requirement；3, in order to make another teeth of two plate gear positive and negative rotation Shi Nengyu gear pairs
Two sides are taken turns without backlash, the pressure of spring will overcome the torque of load, need to increase the torque value or power of power input, make machine
The weight and power consumption of structure increase.
