reverse bearing

Drive idler gear reverse idler gear shaft bearing

空转传动齿轮，怠速齿轮

The reverse bearing B'A'differs from the forward bearing A'B'by 180� �.

反方向角B ’ A ’ 与前进方向角A ’ B ’ 相差180°.

Reverse idler gear shaft bearing Both gear centers have pinions with only half tooth.

回动空转齿轮轴轴承两个齿轮其中心都有一个小齿轮，这个小齿轮只有半边有齿轮。

Reducer, crank pin bearing so small and no reverse impact load that reducer tooth broken, crank pin fracture will not happen.

减速机、曲柄销受力小，无反向冲击负荷，减速机打齿、曲柄销折断的故障不会发生。
