Be provided with pad between the upper surface of baffle ring and housing.
Be provided with a sleeve between through hole and the core wheel.
The upper end of sleeve forms shoulder, and shoulder is resisted against the upper surface of housing, and the lower end of sleeve is set in the through hole.
The upper end of the endoporus of sleeve forms the back taper inclined-plane, the fitting surface of core wheel and sleeve form with sleeve on the back taper inclined-plane that is complementary, back taper inclined-plane.
The position that core wheel is installed on the cardan wheel housing of the present utility model offers a through hole, jacket casing is connected in this through hole, the middle part of core wheel forms baffle ring, the lower end of core wheel is socketed in the sleeve, the lower end of core wheel offers circular groove, " C " shape shell fragment is buckled in the circular groove of core wheel lower end, " C " shape shell fragment is resisted against the lower end of housing, thereby core wheel is fixed on the housing, do not need riveting processing, bearing need be installed, core wheel can be installed on the housing of cardan wheel by assembling simply, it is convenient to replace, and cardan wheel is easy to maintenance.In sum, the utility model is simple in structure, and cardan wheel gets final product by assembling, and processing is simple, and its cost is low, and simultaneously, each parts of cardan wheel are easily realized replacing, and are easy to maintenance.

The specific embodiment:
Form back taper inclined-plane 11 between the baffle ring 7 of core wheel 1 and the axle body of core wheel lower end, the upper end of through hole 5 also forms the back taper inclined-plane, makes the rotation of changeing core 1 more smooth and easy by these two inclined-planes.
Cardan wheel is installed on the product by the upper end of core wheel 1.
Certainly, the lower end of sleeve 4 also can be by the processing of blooming, the lower end that makes sleeve 4 with snap onto on the inside face of housing 2, sleeve 4 is securely fixed on the housing 2 more.Present technology is to rivet processing in core wheel 1 bottom, and core wheel 1 is locked on the housing 2, and in contrast to this, the processing of blooming of sleeve 4 lower ends is simpler, easier realization.
The middle part of described core wheel 1 forms baffle ring 7, the lower end of core wheel 1 is socketed in the sleeve 4, the baffle ring 7 of core wheel 1 is pressed on the shoulder 6 of 4 in cover, the lower end of core wheel 1 offers circular groove 8, " C " shape shell fragment 9 is buckled in the circular groove 8 of core wheel 1 lower end, simultaneously, " C " shape shell fragment 9 is resisted against the lower end of housing 2, thereby core wheel 1 is fixed on the housing 2.Core wheel 1 can be installed on the housing 2 of cardan wheel by assembling simply, does not need riveting processing, does not need bearing, installs simply, replaces conveniently, makes cardan wheel for ease of maintenaince.
The upper end of the endoporus of described sleeve 4 forms back taper inclined-plane 10, the fitting surface of core wheel 1 and sleeve 4 form with sleeve 4 on the back taper inclined-plane 11 that is complementary, back taper inclined-plane 10, be to form back taper inclined-plane 11 between the baffle ring 7 at core wheel 1 middle part and the core wheel 1, more smooth and easy during the cooperation rotation by the back taper inclined-plane 10 on both and 11 of core wheel 1 and sleeve 4.
The middle part of described core wheel 1 forms baffle ring 7, and pad 20 is set in the lower end of core wheel 1, and pad 20 is between the upper surface of baffle ring 7 and housing 2, and pad 20 is effectively avoided the abrasion of housing 2 upper surfaces.Offer a counterbore 22 on the upper surface of housing 2, pad 20 is embedded in this counterbore 22.
For pad 20, in conjunction with known technology as can be known, the area of contact that reduces between pad 20 and the baffle ring 7 can reduce abrasion and friction force.Therefore, pad 20 can also be shaped to the structure shown in Figure 12,13, surface middle part 21 projectioies of pad 20, thus reduce area of contact between pad 20 and the baffle ring 7.
The above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
