Abstract
The utility model relates to a cycloid wheel for RV worm gear reducer, the cycloid wheel that has the shaft hole including the middle part, the cycloid take turns to and be provided with the first eccentric punch combination and the eccentric punch combination of second that surrounds on the shaft hole respectively, first eccentric punch combination form by the first eccentric orfice of a plurality of, the eccentric punch combination of second form by a plurality of second eccentric orfice, first eccentric orfice and second eccentric orfice be crisscross setting the each other, the circumference diameter of first eccentric punch combination is the circumference diameter that is greater than the eccentric punch combination of second, the outer lane of cycloid wheel is provided with a plurality of tooth's socket. A cycloid wheel for RV worm gear reducer, its is rational in infrastructure, has two sets of eccentric orfices, guarantees eccentric orfice and castellated phase relationship, guarantees the phase relationship in profile of tooth and shaft hole, reduces the clamping error.
Description
Technical field
The utility model relates to cycloid wheel field, especially a kind of cycloid wheel for RV worm reduction gear.
Background technique
Cycloid wheel is as the important component part of RV speed reducer, and its Main Function is transmitting torque.Cycloid wheel is by eccentric shaft band action eccentric motion, and in addition, cycloid wheel, while its axis revolves round the sun, also by reverse rotation, also promotes the output mechanism rotation of steel frame construction simultaneously by eccentric shaft.Be meshed with standard pinwheel, be called standard tooth form with pin tooth conjugation and without the form of cycloidal gear tooth of meshing backlass.During practical application Cycloidal pin-wheel drive, for compensating foozle, being convenient to mounting or dismounting and ensureing lubrication, between cycloidal gear teeth and pinwheel tooth, must meshing backlass be had.Therefore, actual cycloid wheel can not adopt standard tooth form, all needs correction of the flank shape.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome above-mentioned middle Problems existing, provide a kind of cycloid wheel for RV worm reduction gear, it is rational in infrastructure, there are two groups of eccentric openings, ensure the phase relationship of eccentric opening and profile of tooth, ensure the phase relationship of profile of tooth and axis hole, reduce clamping error.
The utility model solves the technological scheme that its technical problem adopts: a kind of cycloid wheel for RV worm reduction gear, comprise middle part and there is the cycloid wheel of axis hole, described cycloid wheel is respectively arranged with and is looped around the first eccentric opening group on axis hole and the second eccentric opening group; The first described eccentric opening group is made up of several first eccentric openings; The second described eccentric opening group is made up of several second eccentric openings; The first described eccentric opening and the second eccentric opening are interlaced settings; The circle diameter of described first eccentric opening group is the circle diameter being greater than the second eccentric opening group; The outer ring of described cycloid wheel is provided with some teeth groove.
As preferred scheme, the first described eccentric opening and the second eccentric opening are all three.
As preferred scheme, the diameter of described first eccentric opening is the diameter being greater than the second eccentric opening.
The beneficial effects of the utility model are: a kind of cycloid wheel for RV worm reduction gear, cycloid wheel is respectively arranged with the first eccentric opening group around axis hole and the second eccentric opening group, there are two groups of eccentric openings, ensure the phase relationship of eccentric opening and profile of tooth, also can ensure the phase relationship of profile of tooth and axis hole simultaneously, reduce clamping error.
