Abstract
A Universal joint comprising two joint coupling parts (1, 2) adapted to transmit rotary torque at a universal angle position of the two joint coupling parts (1, 2) thereby each of the two joint coupling parts are formed with a torque like claw the arms (5) of which are axially rotated in relation to each other so as to engage each other over an intermediate coupling means comprising four coupling parts (9-12), which cooperate with the claw arms, and which by a predetermined force (17-20) are constantly pressed towards for from each other and to the sides of the claw arms (5) whereby any play depending on where is automatically eliminated.
Claims11
Universal joint comprising two joint coupling members (1, 2;
- 21, 22) and intermediate coupling means for connecting the two coupling members to transmit rotary torque at a universal angle position between the two coupling members (1, 2;
- 21, 22), each of the two coupling members having a fork like claw (5;
- 23), the two claws which comprise the coupling members being axially rotatable in relation to each other to such angle as to engage each other over the intermediate coupling means (3;
- 25), characterized in that the intermediate coupling means comprises at least four separate coupling parts (9-12;
- 25), and biasing means (19, 32) for urging the coupling parts (9-12;
- 25) towards the two claws to automatically eliminate play within the joint resulting from wear.
Universal joint comprising two joint coupling members (1, 2;
- 21, 22) and intermediate coupling means (3;
- 25) for transmitting rotary torque at a universal angle position between the two coupling members (1, 2;
- 21, 22), each of the two coupling members (1, 2;
- 21, 22) having a fork like claw (5, 23), the claws being rotatable relative to each other about the intermediate coupling means and to an angular position wherein the claws engage each other, and characterized by each pair of claws extending over an angle of more than 180 and said intermediate coupling means (3) including four coupling quadrants (9-12) which in combination are substantially ball-shaped and have an outer diameter larger than the circumscribing diameter of the claws, each of the coupling quadrants (9-12) having a head part defining the outer periphery of the quadrant and a foot part engaging an inner circular arc race (6) of the claw (5) and the foot part of each coupling quadrant has a width slightly less than the width of a cooperating claw to provide slight wear compensating play between the head part and the foot of the adjacent coupling quadrant, and biasing means for urging said quadrants toward said claws.
