As further improvement of the utility model, described circlip for shaft is arranged to the shape that matches with spline housing.
As further improvement of the utility model, described steel ball ball retainer adopts tongue piece to extend and is positioned to circlip for shaft.
The utility model compared with prior art, advantage is:
(1) the utility model is simple in structure, compact, reasonable, cancelled the design of expense pore structure on lower drive shaft in the past, the steel ball ball retainer is improved, by extending at steel ball ball retainer one end a location tongue is set, simultaneously clamp a circlip for shaft at lower drive shaft, arrange one at circlip for shaft and just in time can hold the short slot of locating tongue, described location tongue and short slot cooperatively interact, played the effect of circumferential registration, the circumference that can control better the steel ball ball retainer is movable.
(2) the utility model is arranged to the shape that matches with spline housing with circlip for shaft, can better steel ball be positioned at like this in the R groove between lower drive shaft and the spline housing, further guarantees motor turning lower drive shaft working stability.
Description of drawings
