  • Patent number: 6193014
    Abstract: An apparatus for a ball bearing or needle bearing enclosure having an outside hardened raceway that accommodates two separate compliments of ball bearings located at each end of the raceway to engage with and support a central pin that protrudes in a cone shape out of the bearing enclosure at the front end to make contact with and engage a screw thread. The total bearing and pin assembly is secure in a pocket in the worm wheel having a slip fit mating that allows the total bearing enclosure to move forward and back for a controlled distance against a spring washer of calculated pressure to accept the pressure generated from the cone shaped pin and screw thrust. The central pin is cored out to accept a spiral shaped object for the purpose of pre-spinning the central pin with a jet of pressurized air prior to engaging with the screw thread to eliminate any skidding action between the two surfaces.
