Abstract
The utility model discloses a worm gear support structure of an automotive electric power steering gear. The worm gear support structure comprises steering gear output shafts, a locknut, bearings, a worm gear and a shell, a left and a right bearings are respectively disposed on the steering gear output shafts located on two sides of the worm gear, a groove matching with a circlip is arranged on a hole wall of a bearing hole located at the left end of the shell, a left end surface of the circlip is in contact with a right end surface of an outer ring of the left bearing, and the right bearing is installed in a hole of a support plate located in a hole on the right end of the shell. The worm gear support structure of the automotive electric power steering gear has the advantages of uniform force, small deformation and small footprint.
Description
Technical field:
The utility model relates to the worm gear supporting construction of a kind of support, particularly a kind of vehicle electric power-assisted steering device.
Background technology:
The worm gear of existing deflector is supported for side cantilever supporting construction, this supporting construction discontinuity, and distortion is large, takes up room large.
Summary of the invention:
The utility model object be to provide a kind of stressed evenly, be out of shape worm gear supporting construction little and the little a kind of vehicle electric power-assisted steering device that takes up room.
The technical scheme that realizes the utility model object is, a kind of worm gear supporting construction of vehicle electric power-assisted steering device, comprise deflector output shaft, jam nut, bearing, worm gear and housing, it is characterized in that: on the deflector output shaft of worm gear both sides, be respectively equipped with left and right bearing, on the hole wall of the bearing hole of described housing left end, be provided with the groove matching with jump ring 8, the left side of this jump ring contacts with the right side, outer ring of described left bearing, and described right bearing is arranged in the hole of the stay bearing plate in described housing right-hand member hole.
The utility model have compared with the prior art stressed evenly, be out of shape the little and little remarkable advantage that takes up room.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
The utility model solves the defect of existing cantilever list supporting construction, take following structure, by two bearings on worm gear 5 left side deflector output shafts, be located at respectively on the output shaft 1 of above-mentioned worm gear both sides, wherein the bearing 6 on right side is located in the hole of stay bearing plate 7, the bearing 3 in left side is placed in the left end hole of housing 4, the hole wall in housing left end hole is provided with the groove matching with jump ring 8, the left side of this jump ring contacts with the right side of left bearing outer ring, on the output shaft of the left side of left end bearing, be provided with the outside thread matching with jam nut 2, described back plate press fit in the right-hand member hole of housing.
