Abstract
The utility model discloses an end cover type return rolling spline pair for transmitting torque in rectilinear motion consisting a spline shaft, a spline sleeve and a steel ball. The spline shaft is ringed by the spline; reversers are provided on the two sides of the spline sleeve on the spline shaft; a returning hole is provided on the spline sleeve the inner wall of which is provided with a groove; the spline shaft is also provided with a groove which is overlapped by the groove on the shaft sleeve to form a rolling channel; a returning rolling channel is provided on the surface that opposites to the two reversers; said returning hole, rolling channel and returning rolling channel communicates with each other; the steel ball is positioned in the returning hole, rolling channel and returning rolling channel. The reversers are installed on the two sides of the spline sleeve; when the spline is installed, one end of the reverser is installed first, then, the steel balls are put into the rolling channel, at last, the other end of the reverser is installed, thus, the returning hole, rolling channel and returning rolling channel are full of steel balls. As a result, the noise is reduced, the bearing level is increased.
Description
Technical field
The utility model relates to a kind of spline pair, relates in particular to a kind of end cover type back rolling spline pair that is used for transmitting torque under straight line motion.
Background technique
Rolling spline pair generally is made up of spline housing, splined shaft and back device, the back device of traditional rolling spline pair is installed in spline housing inside, this design steel ball can occur and adorn discontented in raceway in assembling, thereby cause in the process of motion, collision mutually between the steel ball, noise is very big, simultaneously because the back device in spline housing inside, has brought inconvenience to assembling.
Summary of the invention
The utility model provides a kind of end cover type back rolling spline pair that can reduce the operation noise, improve bearing capacity.
The utility model adopts following technological scheme:
A kind of end cover type back rolling spline pair that is used for transmitting torque under straight line motion, by splined shaft, spline housing and steel ball are formed, spline housing is located on the splined shaft, on splined shaft and the both sides that are positioned at spline housing be arranged with the back device respectively, on spline housing, be provided with the backhaul hole, on the inwall of spline housing, be provided with groove, on splined shaft, be provided with groove, groove on the spline housing and the groove on the splined shaft composition raceway that is superimposed with each other, two back devices with the spline housing facing surfaces on be provided with the back raceway, above-mentioned backhaul hole, raceway and back raceway communicate, and steel ball is placed in the backhaul hole, in raceway and the back raceway.
Compared with prior art, the utlity model has following advantage:
The utility model is that the back device designs at the two ends of spline housing with the back device, changes the mode that originally the back device was installed in spline housing inside.In the assembling spline, the back device of an end can be installed earlier, then toward raceway the inside dress steel ball, again the back device of the other end is installed, change original steel ball and can not fill the phenomenon of raceway, thereby steel ball can be riddled in backhaul hole, raceway and the back raceway, reduced noise thus, increased carrying.
