    摘要: A drive assembly including a housing having an opening, a shaft supported for rotation by a bearing assembly received in the opening of the housing, and at least one gear fixed for rotation with the shaft. The bearing assembly includes a bearing that is axially fixed to the shaft, and a sleeve having a tubular section, a radially inwardly extending flange at a first end of the tubular section and a radially outwardly extending flange at a second end of the tubular section. The bearing is received in the tubular section and abuts at least a portion of the tubular section and the radially inwardly extending flange. The radially outwardly extending flange abuts a surface of the housing surrounding the opening of the housing thereby setting an axial position of the at least one gear relative to the opening of the housing.

    摘要: Disclosed is a planetary gear transmission box, comprising a housing portion, a first planetary gear transmission stage, and a second planetary gear transmission stage, wherein the first planetary gear transmission stage comprises a first sun gear (3), a first planetary carrier (5), and a first ring gear; the second planetary gear transmission stage comprises a second sun gear, a second planetary carrier (7), and a second ring gear (6); the first sun gear (3) is connected to an external input element; the first planetary carrier (5) is connected to the second sun gear; the second planetary carrier (7) is connected to an output element; the transmission ratio of the gear transmission box is greater than 25; and the second planetary carrier (7) is directly supported on the housing portion. The locked rotor torque of the gear box is increased, such that the output rotational speed is reduced, and thus a bearing member at the output end can be omitted.

    摘要: A rotary table (1) includes a base body (10), a worm wheel (21), an inner ring (22), a plurality of rolling elements, and a worm screw unit (30). The worm screw unit (30) includes a worm screw (31) held to be rotatable around an axis and having a second gear (31A) meshing with the first gear (215), and a worm screw housing (32) surrounding and holding the worm screw (31) and being fixed to contact the holding surface at a planar contacting surface thereof. One of the holding and contacting surfaces has a cylindrical pin (33) arranged to protrude therefrom. The other of the holding and contacting surfaces has a first recess (11) formed to receive the pin (33), the first recess having a width corresponding to the pin (33) and being elongated in the radial direction of the worm wheel (21).
