Double-clutch speed changer described in the utility model reverses gear the support location structure of idle pulley, including output shaft, fore bearing
And rear bearing, the output shaft are multi-diameter shaft, there is the shaft shoulder, rear end to offer annular slot for axle journal front end；It is described reverse gear it is lazy
The inner hole of wheel is divided into three sections, and the diameter of middle section inner hole is less than the diameter of front and rear sections inner hole, between leading portion inner hole and back segment inner hole
Form positioning convex platform；The fore bearing is mounted in leading portion inner hole, and rear bearing is mounted in back segment inner hole, before the idle pulley that reverses gear passes through
Bearing, rear bearing are mounted on axle journal, and fore bearing realizes that axially position, rear bearing pass through convex by the shaft shoulder, positioning convex platform
Platform, the retainer ring being mounted in annular slot realize axial restraint.
The concrete type of forward and backward bearing can be there are three types of mode: the first is that fore bearing, rear bearing all use deep-groove ball axis
It holds；It is for second that fore bearing, rear bearing all use cylinder roller bearing；The third is that fore bearing uses cylinder roller bearing, after
Bearing uses deep groove ball bearing.
The utility model realizes support and anti-sliding wear using two bearing fits, and passes through the shaft shoulder, positioning convex platform, retainer ring
It realizes axially position (fixation), transmission efficiency is high, and assembles simply, efficiently, to reduce overall cost.
