摘要： The invention relates to an electric drive unit which comprises an electric drive motor and a gear assembly. The electric drive motor has an armature shaft which, for example, proceeds to a worm shaft of the gear assembly, said worm shaft being constructed as one piece with the armature shaft. A first and second bearing are provided for mounting the armature shaft. The second bearing (10) is constructed as a ball bearing which comprises an outer ring (19), an inner ring (20) and balls (21). The inner ring is pressed onto the armature shaft (8) in such a way that it cannot be axially displaced. The outer ring (19) is pushed into a receiving opening (17) which is located in the gear assembly housing (15), and is pressed by a fixing element (24) against an axial stopping face (18) that limits the receiving opening (17). Said fixing element is supported in an installation shaft (23) and comprises springy tongues (28, 29, 30, 31) that are directed against the outer ring (19).

摘要： A curved leaf spring (30) which is a first urging member surrounds an outer wheel (27) of a second bearing (23), and urges, through the second bearing (23), a second end (18b) of a worm shaft (18) in a direction (X2) in which the distance (D1) between the center (C1) of the worm shaft (18) and the center (C2) of a worm wheel (19) is shortened. A second urging member (60) includes an annular support member received by an end surface (27a) of the outer wheel (27) and a plurality of elastic pins (62) extending in a direction in parallel with the axial direction of a support member (61). The elastic pins (62) have fixed ends (62a) fixed to the support member (61) and free ends (62b) that come into elastic contact with an end wall (17b) of a housing (17a).

摘要： A small gap is formed between a worm shaft 3 and a second bearing 20, so that the worm shaft can be tilted relative to the inner ring 20a of the second bearing 20 without fail when preloaded by a torsion spring 14. An elastic member 41 is provided in at least portion of a circumferential groove 40 in the small gap. The worm shaft 3 and the inner ring 20a of the second bearing 20 are not in contact with each other, and their metallic clank in the small gap can be prevented. By providing a projecting portion(s) 3b on one side or both sides, with respect to the axial direction, of the circumferential groove 40, the small gap between the worm shaft 3 and the inner ring 20a of the second bearing 20 can be made large, and it is possible to enlarge the range over which the worm shaft 3 can swing.

摘要： Provided is an electric power steering apparatus comprising a housing, a motor attached to this housing and transmitting an auxiliary steering force to a rotary shaft through a motor shaft, a worm formed on or fitted on the rotary shaft and having a gear portion formed of a metal or a resin, rolling bearings provided in the housing, disposed respectively in positions on both sides of the worm and rotatably supporting the rotary shaft, an output shaft transmitting a steering force for steering an axle and rotatably supported in a predetermined position of the housing, and a worm wheel formed on or fitted on the output shaft in a way that meshes with the worm and having a gear portion formed of the resin, wherein a pre-load mechanism for applying a pre-load acting towards the worm wheel is provided at a shaft end portion, distal from the motor, of the rotary shaft. The thus simply-constructed electric power steering apparatus is capable of eliminating an existence of a backlash and reducing tooth-butting noises without any decline of a power transmitting performance.

摘要： The axial play of a gearbox shaft (3) which meshes with a gearbox output (7) is detected by the translational travel of the rotationally driven gearbox shaft (3) between the axial end stops (A1; A2) thereof while the gearbox output (7) is blocked at the same time, whereby said end stops define the axial play. The commutator-dependent ripple of the motor current (IM) pertaining to a commutator motor which drives the gearbox shaft (3) in a drive unit (1; 2) is evaluated as the representative variable for the travel.

摘要： The invention relates to a drive device (1) comprising an electric drive motor (2), a housing (4), at least one shaft (8) which is driven by the drive motor and means for compensating the axial clearance of said shaft. The invention is characterized in that a spring ring disk (19), which can be expanded radially counter to an elastic force and has two stopping surfaces radially extending towards each other on the axis of the shaft in the form of a wedge, is arranged on the shaft as said compensating means. The invention is also characterized in that shaft has a ring-shaped projection (22) which matches one of stopping surfaces and the housing has an annular collar(23) which matches the other stopping surface. The spring ring disc (19) is pre-tensed and arranged in between the projection (22) and the annular collar (23).
