Specific implementation mode
Below in conjunction with the accompanying drawings, it elaborates to the specific implementation mode of the present invention.
As shown in Figure 1, since the pin slot tooth form of existing RV retarders pin wheel housing 1 is all made of diameter directly slightly larger than pin 2
The standard circular arc of diameter, pin 2 is by position relationship after radial pressure as shown in Fig. 2, 2 radius R1 of pin is slightly less than in pin wheel housing 1
Pin groove radius R2, so the pin slot tooth form of pin 2 and pin wheel housing 1 with single-contact, can cause pin 2 in needle tooth in movement
Minor rotation and shaking in 1 pin slot of shell, to influence the transmission accuracy of cycloid motion, protect accuracy life and transmission stability.
As shown in figure 3, the present invention proposes that a kind of precision higher, the pin slot tooth form of longer life expectancy are that semiellipse arc or class are ellipse
The pin wheel housing of circular arc；The present invention 1 center pillar cotter way tooth form of pin wheel housing be semiellipse arc or class elliptic arc, pin wheel housing of the invention its
Remaining part separation structure and the counter structure of existing RV retarders pin wheel housing are completely the same；Class elliptic arc include two sections of curve arcs, two sections
Curve arc is about symmetrical by the radius of two sections of curve arc intersection points；The radius of curvature of any two points is unequal on curve arc；Such as
Shown in Fig. 4, pin 2 with the present invention 1 center pillar cotter way of pin wheel housing at two-point contact and with 1 center pillar cotter way of pin wheel housing of the present invention most
Big radial clearance is d1, and d1 value (4 μm are taken in the present embodiment) in 3 μm~5 μm, which is used for oil storage, makes
Pin 2 in cycloid motion the present invention pin wheel housing between without shaking, to ensure cycloid motion stability higher, service life
Longer, precision higher.
In order to form the pin wheel housing pin slot for meeting design requirement of the present invention, two kinds of new grinding wheel manufacturers are proposed
Method.
