  • Universal joint
    Patent number: 4135372
    Abstract: A pre-loading structure between the driving member and the driven member removes torsional backlash from a universal joint by pre-loading a pair of blocks against and substantially encompassing the driving member. The blocks are dimensioned so that the inside of each block has surfaces which face one another in spaced relationship to provide a clearance between them to allow the blocks to be moved toward each other as wear occurs to continually maintain the pre-load between driving and driven member.
