Description

A kind of RV deceleration eccentric drive shaft
Technical field
The present invention relates to reducer technology field more particularly to a kind of RV deceleration eccentric drive shafts.
Background technique
Double crank shaft is key part on RV cycloidal planetary gear speed reducer, and both ends are equipped with conical bearing, and main movement is It crosses Needle bearing and removes driving RV gear again.Current double-eccentric shaft is the problem is that processing technology requires high, equipment requirement The defects of being completely bonded is not easy with the needle bearing on eccentric disc when high and transmission.
Summary of the invention
The purpose of the present invention is to solve the shortcomings of the prior art and a kind of RV deceleration eccentric drive shaft is provided, the RV speed reducer Eccentric shaft is novel in design, structure is simple, the precision and convenience for simplifying manufacturing process, improving assembly, reduces transmission drop It is low because of the undesirable noise of precision, shake, reduce difficulty of processing and reduce equipment investment.
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.
Fig. 1 is the structural diagram of the present invention.
Include in Fig. 1:
1 --- shaft body 11 --- spline
2 --- eccentric wheel 1 --- eccentric wheels two
22 --- Needle bearing 23 --- conical bearings one
24 --- conical bearing two.
Specific embodiment
Below with reference to specific embodiment, the present invention will be described.
As shown in Figure 1, a kind of RV deceleration eccentric drive shaft, includes shaft body 1, if the outer diameter upper end of shaft body 1 is provided with Dry spline 11,1 upper end of shaft body is set with adjacent eccentric wheel 1 and eccentric wheel 2 21, and corresponding with spline 11 Match, eccentric wheel 1 and 2 21 upper end of eccentric wheel are set with Needle bearing 22, and the right side of eccentric wheel 1 is installed with conical bearing one 23,2 21 left side of eccentric wheel is installed with conical bearing 2 24, and conical bearing 1 and conical bearing 2 24 are set in shaft body 1 End, and with 11 Corresponding matching of spline and be set to eccentric wheel 1 and 2 21 two sides of eccentric wheel.
Preferred as the present embodiment, the eccentric wheel 1 is with the eccentric wheel 2 21 with the bearing pair of the shaft body 1 Title is set in 1 upper end of shaft body.
Preferred as the present embodiment, the conical bearing 1 is to be left and right symmetrically arranged with the conical bearing 2 24.
Preferred as the present embodiment, the conical bearing 1 is set in the right end upper end of the shaft body 1.
It need to further explain, the present invention is set with eccentric wheel one by being provided with spline 11 in shaft body 1 2 and eccentric wheel 2 21, i.e., traditional double crank shaft is resolved into eccentric wheel and two kinds of elements of splined shaft, utilizes the side of spline 11 Formula carries out the pairing and transmission in angle, and simplifying from manufacturing process is improved in adjustment when assembled and precision, reduces Transmission is reduced because of precision undesirable noise and shake;It reduces difficulty of processing and reduces the investment of equipment;Therefore it is of the invention Simple, the precision and convenience for simplifying manufacturing process, improving assembly with novel design, structure, reducing transmission reduces Because of the undesirable noise of precision, shake, the advantages of reducing difficulty of processing and reduce equipment investment.
The above is only a preferred embodiment of the present invention, for those of ordinary skill in the art, according to the present invention Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to the present invention Limitation.
