Abstract

The invention provides an angle-adjustable three-pivot universal joint, which includes three pivots, rollers and an outer part of the universal joint. The inner wall of the outer part of the universal joint has a raceway, and the roller is placed on the In the raceway and along the raceway, the shaft head on the three pivots is placed in the inner cavity of the roller; the outer peripheral surface of the roller is in line contact with the inner wall of the raceway, and the roller and the raceway In the axial section, the contact line between the roller and the raceway is two straight lines that are separated from each other and can extend to intersect. The invention increases the contact area, reduces the stress of the contact point, increases the fatigue life of the roller and the raceway, and reduces the friction between the roller and the raceway.

Description

technical field [0001] The invention relates to a three-pivot universal joint, in particular to a three-pivot universal joint with adjustable angles. Background technique [0002] When the three-pivot universal joint is running, there is relative motion and friction between the rollers rotating around the three-pivot shaft head and the raceway of the outer part of the universal joint, which makes the universal joint unfavorable. Slip resistance and axially derived force for smooth operation. The greater the friction between the rollers and the raceway, the greater the slip resistance and axial derived force of the universal joint. [0003] Such as figure 1 As shown, the roller 2 of the three-pivot universal joint can freely deflect around the shaft head 31 of the tripod shaft 3 (the shaft head is generally spherical). When the universal joint operates at a swing angle, the roller 2 may not deflect along with the three pivots 3, and always remain parallel to the raceway 11...
