Embodiment Construction
[0017] Such as figure 2 , image 3 As shown, the present invention is composed of an inner ring 1, an oil seal 2, a cage 3, a steel ball 4, an outer ring 5, a bolt 6, a sealing baffle 7, a retaining ring 8 for a hole, a gland 9, and an oil nozzle 10; the inner ring 1 There is a spline through hole or an inner hole with a keyway to cooperate with the corresponding shaft extension, and there is a spherical ring boss on the outer diameter of the inner ring 1, which is matched with the inner spherical surface of the cage 3. The inner ring 1 and the outer ring 5 Two groups of steel balls 4 are installed between them, and the specific number of steel balls 4 is determined by the required transmission capacity and internal geometric dimensions; there are multiple contact parts on the inner ring 1 and outer ring 5 that are in contact with the steel balls 4 and are evenly distributed along the circumference. Oval or circular straight channel, the torque is transmitted through the cha...
