Adjustable locknut assembly

An improved locknut assembly for mounting on a shaft, comprising:

• a first member for engagement with the shaft to provide a predetermined torque force having an internal aperture extending longitudinally through it of a size to accommodate the shaft and a series of longitudinal external grooves on its periphery, of a fine pitch, the first member has a cylindrical configuration with the series of grooves being adjacent to each other and extending about the entire outer surface;
• a second member extending over both the shaft and the first member to cover the cylindrical exterior surface of the first member, the second member has an internal hollow cylindrical configuration, the second member is removable from the first member and capable of being fixedly connected to the first member at numerous positions about the first member to accommodate the desired predetermined torque force, the second member having an internal aperture extending longitudinally through the second member to accommodate the shaft and a series of longitudinal internal grooves on the internal cylindrical peripheral surface substantially complementary to the first member's external grooves to permit an adjustable fixing of the first and second members;
• and
• means for securing the first member and second member together in a fixed position relative to the shaft.
