Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
The mentality of designing of the application: in order to the deep groove ball bearing design size of the duplex fork inside that can make duplex driving-shaft assembly is enough large, reach certain moment of torsion again, duplex fork inner chamber secures size again, so only have the annex volume reducing fixing deep groove ball bearing, or the annex of fixing deep groove ball bearing is removed, object is exactly that the reduction of the annex volume of fixing deep groove ball bearing or annex are removed, or annex is stashed, make it to occupy the space of a very little part, the moment of torsion of transmission shaft can be increased again, do not affect again the corner of transmission shaft.
See Fig. 1 to Fig. 6, a kind of transmission shaft of the hidden apparatus with fixing deep groove ball bearing, comprise spline fork assembly and weld yoke assembly, between described spline fork assembly and weld yoke assembly, duplex joint is set, described duplex joint has: the spline jaw being positioned at spline fork assembly end, and described spline jaw end arranges clutch shaft bearing hole (clutch shaft bearing hole is arranged on clutch shaft bearing seat); Be positioned at the solder plug of weld yoke assembly end, described solder plug end arranges the second bearing hole (the second bearing hole is arranged on the second bearing support); Duplex fork, its by Hooke's joint respectively with spline jaw and weld jaw and be connected, the slide block of band spindle nose is arranged in described duplex fork, described spindle nose is respectively the left spindle nose being positioned at left side and the right spindle nose being positioned at right side, and described slide block is arranged on duplex fork inner chamber by the pad being arranged in both sides.
Described clutch shaft bearing hole inner circumferential arranges the first concave ring groove, first periphery, deep groove ball bearing outer ring arranges the second concave ring groove, described first deep groove ball bearing is arranged in described clutch shaft bearing hole, and to coordinate with the second concave ring groove in the left annular groove that formed at the first concave ring groove the first back-up ring is set, and by described back-up ring, described first deep groove ball bearing is fixed in described clutch shaft bearing hole.
Described second bearing hole inner circumferential arranges the 3rd concave ring groove, described second periphery, deep groove ball bearing outer ring arranges the 4th concave ring groove, described second deep groove ball bearing is arranged in described second bearing hole, and to coordinate with the 4th concave ring groove in the right annular groove that formed at the 3rd concave ring groove the second back-up ring is set, and by described second back-up ring, described second deep groove ball bearing is fixed in described second bearing hole.
