In the prior art, the structure of automotive reverse gear speed change gear is that speed change gear and gear shaft are structure as a whole, in gearbox, rotate with respect to gear box casing, speed change gear is two gears that diameter differs, and this two gear makes automobile produce different speed while work separately.Because needs speed change gear rotates with respect to gear box casing, therefore between gear shaft and gear box casing, adopt the needle bearing with outer ring to carry out radial location, adopt clamping stopper bearing to carry out axially locating.When assembling, need first press-fit the needle bearing of band outer ring, two ends, refill and join thrust bearing, last assembling gear assembly.
Because the automotive reverse gear speed change gear of this structure needs two needle bearing and two clamping stopper bearings with outer ring, cost is high on the one hand, between gear box casing and gear shaft, need to press-fit the needle bearing with outer ring, high to gear box casing housing bore and gear shaft requirement on machining accuracy, and needle bearing with outer ring need press-fit, assembling is complicated, reprocesses difficulty large.
Model utility content
For the problems referred to above, the utility model provides novel vehicle reverse gear speed change gear, its simple in structure, easily assembling.
The technological scheme that the utility model is taked is:
Novel vehicle reverse gear speed change gear, comprise gear shaft, gearwheel, small gear and gear box casing, described gearwheel and small gear are contained on gear shaft by bearing housing respectively, and a side that is set with small gear on gear shaft is provided with the check plate that stops gearwheel and small gear generation axial float; A side that is set with gearwheel on gear shaft is set with the stop sleeve that stops gearwheel and small gear generation axial float.
For further improving the operational efficiency of bearing, described bearing is needle bearing.
For gearwheel and small gear are rotated with respect to gear box casing, insert in gear box casing at the two ends of described gear shaft, and at least between one end and gear box casing, pass through rivet.
For stoping gear shaft with respect to gear box casing generation axial float, the one end of inserting on gear shaft in gear box casing is provided with the check plate of prevention gear shaft with respect to gear box casing generation axial float.
For avoiding check plate and gear box casing contacting point on gear shaft to wear and tear because of friction, be set with packing ring at check plate and gear box casing contacting point.
For further strengthening the effect that stops gearwheel and small gear that axial float occurs on gear shaft, the position that described stop sleeve end contacts with gearwheel is provided with pressurized ring.
For making not interfere the rotation of speed change gear on gear shaft, described check plate and stop sleeve all withstand on the interior ring of bearing.
For avoiding wearing and tearing because of friction between check plate on gear shaft and the bearing of small gear, between check plate and the bearing of small gear, be set with packing ring.
For avoiding between the bearing of gearwheel and stop sleeve because friction is worn and torn, between the bearing of gearwheel and stop sleeve, be set with packing ring.
Because the utility model has adopted technique scheme, two needle bearing and two clamping stopper bearings with outer ring are not only saved, also reduce the machining accuracy demand of gear shaft end, also reduced simultaneously rotatable parts quality, reduced the friction area between bearing and gear shaft, thereby played the effect that reduces oil consumption.
