What does it mean that the two supports are symmetrically distributed relative to the pinion? machine design
Bearings are support. Two support relative small gear do symmetrical distribution, that is, the gear center and the two bearing center distance requirements equal, the last figure, you see understand.When designing the structure of the shaft, we should first design and install the shaft section of the gear, then design other shaft sections, that is to say, from the middle to the sides, so that the "two supports" can be symmetrically distributed relative to the small gear".
In the design of gear reducer,Gears are generally attached to shafts by keyway. The two ends of the shaft are driven by bearingsSupport. If your keyway is in the middle of the shaft, then supportSymmetrical distribution with respect to the pinion.
This is a condition in determining the gear tooth width coefficient.The symmetrical distribution of the two support relative to the pinion means that:
