Abstract:
In a worm wheel for a roller worm drive, each roller is movable along its axis relative to the body of the wheel, and biased towards an extended position by a spring. The springs are mounted in the space between inboard and outboard bearings associated with each roller, so as to conserve room within the roller wheel and hence permit use of large, robust, anti-friction bearings. In particularly preferred arrangements, the outboard anti-friction bearing can be used to limit outboard movement of each roller relative to the wheel body, and may also serve to transmit inboard-directed thrusts from the roller to the body via the biasing spring. The overall arrangement provides enhanced load carrying capacity and compactness in roller worm drives.
