Definitions
- the invention is related to the field of universal joints and in particular to a telescopic triplan universal joint.
- Telescopic triplan universal joints such as taught by Orain in U.S. Patents 4,490,126; 4,619,628; and 4,828,534 have an outer joint member 10 and an inner joint member 12 as shown in Figures 1 and 2.
- the outer joint member 10 normally has three symmetrically disposed chambers, each chamber having a pair of opposing side walls. Each side wall in each chamber has a flat longitudinal guideway 14 which runs parallel to the axis of rotation of the outer joint member.
- the longitudinal guideways 14 are spatially separated and parallel to each other.
- the inner joint member consists of a spider member 16 which may be connected to a shaft 18.
- the spider member 16 has three equally spaced radially extending trunnions 20. Each trunnion 20 extends into one of the chambers in the space between a pair of longitudinal guideways 14 as shown in Figure 2.
- a button 22 and a planar roller bearing 24 Disposed between each trunnion 20 and the adjacent longitudinal guideway 14 is a button 22 and a planar roller bearing 24.
- the button 22 has a concave surface which mates with the spherical surface of the trunnion 20 and a flat surface which engages the surface of the planar roller bearing 24 on the side opposite the longitudinal guideway 14.
- the planar roller bearing 24 has a rectangularly shaped cage 26 in which are journaled a plurality of needle bearings 28.
- the cage 26 also has a pair of lateral guides which are received in grooves provided on the opposite side of the longitudinal guideways 14 and a pair of transverse lips or stops 30 provided at its opposite ends to maintain the button 22 in contact with the surface of the planar roller bearing 24.
- the transverse stops 30 are to prevent the button 22 from being disengaged from the planar roller bearing 24 when the inner joint member 12 is displaced at an angle relative to the outer joint member 10.
- a spring (not shown) is used between the stops on the planar roller bearing and the button to help maintain the center of the planar roller bearing under the button.
- the invention is a telescopic triplan universal joint having an outer joint member and an inner joint member.
- the outer joint member has three symmetrically disposed chambers extending longitudinally therein about an axis of rotation of the outer joint member.
- Each symmetrically disposed chamber has a pair of spatially separated opposing side walls and each side wall has a longitudinal guideway.
- the inner joint member has three equally spaced radially extending trunnions which individually extend into one of the three symmetrically disposed chambers and extend between the longitudinal guideways.
- Each of the trunnions has a spherical surface facing each of the guideways.
- Each of the guideways is engaged by a planar roller bearing which is longitudinally movable therealong.
- a movable race is disposed between each planar roller bearing and the adjacent trunnion.
- the movable race has a flat surface engaging the planar roller bearing on the side opposite the guideway and a concave trunnion seat pivotally engaging the spherical surface of the trunnion.
- the movable race also has a transverse stop abutment provided at each end which extends from the flat surface engaging the planar roller bearing towards the guideway to limit the longitudinal displacement of the planar roller bearing therebetween.
- Another object of the invention is to provide the stops for the planar roller bearing on the movable race. Still another object of the invention is to permit limited unrestricted movement of the planar roller bearing by separating the stops provided on the movable race a distance greater than the length of the planar roller bearing.
- Figure 1 is a partial cross-sectional side view of the prior art triplan universal joint
- Figure 2 is a cross-sectional end view of a prior art triplan universal joint
- Figure 3 is a partial cross-sectional side view showing the relationship between the planar roller bearing and the button;
- Figure 4 is a partial cross-sectional side view of a triplan universal joint incorporating the invention;
- Figure 5 is a cross-sectioned end view of the triplan universal joint shown in Figure 4 taken along lines 5 - 5;
- Figure 6 is a partial cross-sectional side view showing the details of the movable race taken along lines 6 - 6 of Figure
- Figure 7 is a perspective view of the movable race; and Figure 8 is a perspective view of a planar roller bearing.
- FIG. 4 is a partial cross-sectional view of a telescopic triplan universal joint embodying the invention.
- the universal joint has an outer joint member 32 and an inner joint member 34.
- the outer joint member 32 has three equally spaced longitudinal chambers 36 generally parallel to the axis of rotation 38 of the outer joint member.
- Each longitudinal chamber 36 has a pair of face-to-face spatially separated side walls. In each of these side walls a recessed longitudinal guideway 40 is formed which extends parallel to the axis of rotation 38.
- the longitudinal guideways have flat surfaces which are parallel to the surface of the longitudinal guideway provided on the opposite wall.
- the inner joint member 34 has a spider member 44.
- the spider member 44 may be made integral with a shaft 46 or the spider member 44 and the shaft 46 may be separate elements rotatably joined to each other by mating splines 48 and axially locked by a lock washer 50 received in annular grooves provided in both the shaft and the spider member as shown in Figure 4.
- the spider member 44 has three equally spaced radially extending trunnions 52, one of the trunnions 52 extending into each chamber 36 as shown in Figure 5. At least a portion of the external surface of each trunnion 52 has a spherical shape as shall be explained later herein.
- a movable race 54 and a planar roller bearing 56 are disposed between each trunnion 52 and the adjacent recessed guideways 40 of the associated chamber 36.
- the planar roller bearing 56 has a plurality of pin bearings 58 journaled in a rectangular cage member 60.
- the pin bearings 58 rollingly engage the flat surface of the longitudinal guideway 40.
- the movable race 54 has a flat surface 62 which rollingly engages the pin bearings 58 on the side opposite the guideway 40.
- a transverse cylindrical trunnion seat 64 is disposed on the side of the movable race opposite the flat surface 62.
- the movable race 54 also has a pair of stop abutments 66 disposed at its opposite ends which extend into the recessed guideway 40 on either side of the planar roller bearing 56.
- the curvature of the cylindrical trunnion seat 64 mates with the spherical external surface of the trunnion 52.
- the cylindrical trunnion seat 64 permits the movable race to remain in the recessed longitudinal guideways when the position of the spherical surface of the trunnion which contacts the cylindrical trunnion seat 64 is radially displaced as a result of the inner joint member 34 being disposed at an angle relative to the outer joint member 32.
- the distance between the stop abutments 66 is greater than the length of the planar roller bearing 56 so that when the angle between the inner and outer joint members is less than a predetermined angle, the pin bearing assembly will not be engaged by the stop abutment 66 as the movable race 54 oscillates with the rotation of the universal joint. However, the stop abutment 66 will engage and displace the planar roller bearing 56 along the longitudinal guideway 40 when the relative axial position of the inner joint member to the outer joint member is changed or the angle between the inner joint member and the outer joint member exceeds a predetermined angle.
- the details of the planar roller bearing 56 are shown in
- FIG 8. As previously indicated, a plurality of pin bearings 58 are journaled in a rectangular cage member 60.
- the width of the cage member 60 is selected so that it is slidably received in the recessed longitudinal guideways 40. It is not necessary that the entire external surface of the trunnion 52 have a spherical surface as shown in Figure 4.
- the external surfaces of the trunnion 52 which engage the cylindrical trunnion seat 64 of the movable race needs to be spherically shaped.
- the portion of the external surfaces of the trunnion which do not engage the cylindrical trunnion seat 64 may be flat as shown in Figure 1 or have any other shape known in the art.
- the details of the movable race 54 are more clearly shown in the perspective view shown in Figure 7.
- the advantages of placing the stop abutments 66 on the movable race are that the loaded cross-sectional area of the stop abutments 66 may be significantly increased over the structures taught by the prior art, as illustrated in Figure 3. Further, a higher structural steel may be used in the fabrication of the movable race, and the movable race may be heat treated to optimize its strength which was not possible when the stops were formed on the cage. As a result, a significant improvement in the durability of the triplan universal joint has been obtained.
