Provided is a geared motor with which a large torque can be obtained without an increase in size. In this geared motor (1), an output member (8) having a helical groove (83) formed in an outer circumferential section is provided between a first plate part (31) and a second plate part (32) of a frame (3), and the rotation of a motor pinion (55) fixed to a rotary shaft (50) is reduced in speed by transmission gears of a reduction gear mechanism (9) and is transmitted to a gear part (85) of the output member (8). Thus, a large torque can be output, even when the gear part (85) of the output member (8) is made smaller than the outer diameter of the section (84) provided with the helical groove (83). Also, even when a gear cover (7) is provided, a lateral plate part (72) of the gear cover (7) covering the outer circumferential section of the gear part (85) of the output member (8) is located close to the rotation center axis of the output member (8). Thus, it is possible to prevent the geared motor (1) from being increased in size by the gear cover (7).

A bearing device includes a support having a bearing hole, a shaft member slidably inserted into the bearing hole thereby to be rotatably supported by the support, the shaft member having an axial end surface and a locking part located on the axial end surface of the shaft member to protrude in an axial direction of the shaft member from an outer periphery of the axial end surface of the shaft member. The locking part is deformed by force applied to its axial protruding end so as to bulge outward in a radial direction intersecting the axial direction, so that the bulging part is capable of being locked to a peripheral part of the bearing hole on an outer surface of the support.

A shaft assembly may include two or more Poka-Yoke bearing caps, each Poka-Yoke bearing cap having a pair of reference bores offset from a central axis of the bearing cap by differing offset distances, and each bearing cap defining a semi-circular recess that is positioned so as to align in use a central axis of the semi-cylindrical recess in the bearing cap with an axis of rotation of a shaft rotatably supported by the bearing cap. The differing offsets of the reference bores prevent the bearing cap from being assembled in a reversed orientation. To ensure that each bearing cap can only be fitted in one position, a centre spacing between the first and second reference bores of each bearing cap is different to the centre spacing used for other bearing caps used to support a single shaft.

A press-fit thrust bearing system and apparatus. A press-fit thrust bearing for an electric submersible pump includes a protruding band extending around a midsection of a bushing, the protruding band extending inward towards a drive shaft, outward towards a diffuser, or both. When extending outwardly, the band is press-fit into the diffuser to prevent dislodgment of the bushing. A non-rotating guide sleeve extends around the bushing above the protruding band, the guide sleeve interlocking with the protruding band to prevent rotation of the bushing. The guide sleeve includes a projection, the protruding band has a channel and the projection mates with the channel to form the interlock. A pair of flanged, rotatable bearing sleeves extend inwards of the single bushing and are keyed to the drive shaft. The top and bottom faces of the bushing serve as thrust handling surfaces.
