In order to achieve the above objectives, the present invention is achieved through the following technical solutions.
A kind of RV deceleration eccentric drive shaft, includes shaft body, and the outer diameter upper end of shaft body is provided with several splines, axis
Ontology upper end is set with adjacent eccentric wheel one and eccentric wheel two, and with spline Corresponding matching, eccentric wheel one and eccentric wheel two
Upper end is set with Needle bearing, and the right side of eccentric wheel one is installed with conical bearing one, is installed with conical bearing on the left of eccentric wheel two
Two, conical bearing one and conical bearing two are set in shaft body upper end, and with spline Corresponding matching and be set to eccentric wheel one
With two two sides of eccentric wheel.
Wherein, the eccentric wheel one is symmetrically set in the shaft body with the eccentric wheel two with the bearing of the shaft body
Upper end.
Wherein, the conical bearing one is to be left and right symmetrically arranged with the conical bearing two.
Wherein, the conical bearing one is set in the right end upper end of the shaft body.
Beneficial effects of the present invention are：A kind of RV deceleration eccentric drive shaft of the present invention, includes shaft body, shaft body
Outer diameter upper end be provided with several splines, shaft body upper end is set with adjacent eccentric wheel one and eccentric wheel two, and with flower
Keyway Corresponding matching, eccentric wheel one and two upper end of eccentric wheel are set with Needle bearing, and the right side of eccentric wheel one is installed with cone axis
One is held, is installed with conical bearing two on the left of eccentric wheel two, conical bearing one and conical bearing two are set in shaft body upper end, and with
Spline Corresponding matching is simultaneously set to eccentric wheel one and two two sides of eccentric wheel.The present invention in shaft body by being provided with spline
Slot, and be set with eccentric wheel one and eccentric wheel two, i.e., traditional double crank shaft is resolved into eccentric wheel and two kinds of elements of splined shaft,
The pairing and transmission in angle are carried out in the way of spline, from manufacturing process simplification and adjustment when assembled and precision
Improved, reducing transmission reduces because of the undesirable noise of precision and shake；It reduces difficulty of processing and reduces equipment
Investment；Therefore the present invention has novel design, structure simple, the precision and convenience for simplifying manufacturing process, improving assembly, drop
The advantages of low transmission reduces because of the undesirable noise of precision, shake, reduces difficulty of processing and reduce equipment investment.
Detailed description of the invention
The present invention is further detailed below with attached drawing, but the embodiment in attached drawing is not constituted to this hair
Bright any restrictions.
