Abstract
The utility model provides a bearing axial positioning device, inherent bearing installation department of speed reducer box is equipped with the jump ring groove, can block including the outer fringe and establish the retaining ring of jump ring inslot, the retaining ring is the ring -type, and the retaining ring center is equipped with and only supplies a shaft hole of passing, the retaining ring is assembled by a plurality of arc piece and is formed, and the connection can be dismantled through fixing device to adjacent arc piece. The retaining ring is assembled by 4 arc pieces and is formed. Fixing device is the screw, the both sides of arc piece all are equipped with half of screw hole, the screw is screwed up in the screw hole that is made up by two half of screw holes to connect two adjacent arc pieces. The screw is interior hexagonal awl end holding screw. The utility model discloses simple structure, convenient handy, axial positioning is effectual, and is applicable in snap rings for hole and the unable occasion of using of the box shaft shoulder, has reduced die sinking cost and environment resource's waste.
Description
Technical field
This utility model relates to a kind of bearing axial direction positioning device.
Background technology
The axially location of the bearing in casing is generally adopted hole back-up ring or the casing shaft shoulder, adopts the back-up ring location, hole can only gear shaft bearing outer-ring, it is impossible to gear inner ring. The casing shaft shoulder all has difficulties for withdrawing pattern the casing of complex model and built-in core rod, and design and use all have difficulties, and can be greatly increased the waste of die sinking cost and environmental resource.
Summary of the invention
A kind of bearing axial direction positioning device is the utility model proposes for solving the problems referred to above.
The technical solution adopted in the utility model is:
A kind of bearing axial direction positioning device, bearing installation place, box body of speed reducer inherence is provided with jump-ring slot, the back-up ring in described jump-ring slot can be fastened on including outer rim, described back-up ring is in the form of a ring, back-up ring center is provided with the axis hole being intended for axle traverse, described back-up ring is assembled by several arc-like sheets, and adjacent arc-like sheet is removably connected by fixing device.
Further, described back-up ring is assembled by 4 pieces of arc-like sheets.
Further, described fixing device is screw, and the both sides of described arc-like sheet are equipped with half of screw hole, and described screw-driving is in the screw hole being combined into by two half of screw holes, to connect adjacent two arc-like sheets.
Further, described screw is interior hexagonal tapered end holding screw.
The beneficial effects of the utility model are: simple in construction, facilitate handy, axial good positioning effect, be applicable to hole back-up ring and occasion that the casing shaft shoulder cannot use, decrease the waste of die sinking cost and environmental resource.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
This utility model is further illustrated below in conjunction with accompanying drawing:
A kind of bearing axial direction positioning device, the inherent bearing installation place of box body of speed reducer 1 is provided with jump-ring slot, the back-up ring 2 in described jump-ring slot can be fastened on including outer rim, described back-up ring 2 is in the form of a ring, back-up ring center is provided with the axis hole being intended for axle traverse, described back-up ring 2 is assembled by several arc-like sheets 21, and adjacent arc-like sheet 21 is removably connected by fixing device 3.
Described back-up ring 2 is assembled by 4 pieces of arc-like sheets 21.
Described fixing device 3 is screw, and the both sides of described arc-like sheet 21 are equipped with half of screw hole, and described screw-driving is in the screw hole being combined into by two half of screw holes, to connect adjacent two arc-like sheets 21.
Described screw is interior hexagonal tapered end holding screw.
Back-up ring 2 snaps in jump-ring slot by outer rim, to be fixed on box body of speed reducer 1, if but whole back-up ring 2 is snapped in jump-ring slot, can be relatively difficult, and back-up ring 2 can be divided into piecemeal arc-like sheet 21 and snap in one by one in jump-ring slot by this utility model, it is connected with each other again through screw and fixes, convenient with regard to very comfortable; Owing to back-up ring 2 area is relatively big, both can having blocked bearing inner race, and can block again bearing outer ring, axial locating effect is better than hole back-up ring, compared with the shaft shoulder, handy more flexibly again.
Content described in this specification embodiment is only enumerating of the way of realization to utility model design; protection domain of the present utility model is not construed as being only limitted to the concrete form that embodiment is stated, protection domain of the present utility model also include those skilled in the art according to this utility model design it is conceivable that equivalent technologies means.
