Description
Technical field
The utility model relates to a kind of engineering machinery, is specifically related to a kind of ring gear and semiaxis spindle-end looseness-proof device of engineering machinery chassis ransaxle.
Background technique
In the engineering machinery chassis ransaxle transmission system, its ring gear is installed in the end of semiaxis, and fixes with tightening nut.Loosening in order to prevent tightening nut, at present, most of producers all adopt big nut locking at home, and rush the anti-loose structure of flange enclasping type with riveting, and there is following shortcoming in this anti-loose structure:
(1) maintenance is poor, and particularly during operation in the open air, because wheel operating space, limit is narrow and small, flange is rushed in riveting to be needed to restore, and larger locking nut is turned round down, and these work all are the time-consuming again difficult things of extremely requiring great effort.
(2) because this structure belongs to damage type locking, the not reproducible utilization of locking nut.After large locking nut screws off, substantially do not possess the value of re-using yet, cause unnecessary waste.
(3) size of flange is rushed in riveting, can only lean on workman's experiential operating, and random impact is larger, and conformity is poor, so that fastening ability is uncertain, affects fastening effect, brings potential safety hazard.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of engineering machinery chassis ransaxle ring gear spindle-end looseness-proof device, and at the arranged outside locked spacer of lace nut, locked spacer is camber plate shape, and outer claw and interior claw are arranged.After the lace nut screws, locked spacer is attached on the outer side surface of lace nut, and outer claw is bumped in the keyway of lace nut; Interior claw is bumped in the elongated slot of hub carrier.The arranged outside jump ring of locked spacer, jump ring is bumped in the jump-ring slot of hub carrier.The inside and outside claw of locked spacer has limited the relative movement of lace nut and hub carrier, and nut can not become flexible, come off, and reaches fastening locking purpose.
The utility model is achieved by the following technical solution: a kind of engineering machinery chassis ransaxle ring gear spindle-end looseness-proof device, it comprises: locking nut, hub carrier and ring gear.Described ring gear is installed in the end of hub carrier by spline, and there is screw thread the end of described hub carrier, and locking nut is fixed on ring gear on the hub carrier by screw thread.It is characterized in that: described locking nut is the lace nut, is milled with keyway on the end face without threaded end of lace nut, and described keyway is a plurality of, and a plurality of keyways are along central shaft to even distribution; The axle head of described hub carrier has the elongated slot of a plurality of symmetries, makes jump-ring slot on the external cylindrical surface of hub carrier; The arranged outside locked spacer of described locking nut, described locked spacer are camber plate shape, and there is outer claw in the outside of camber plate, and there is interior claw the inboard of camber plate.After locking nut screws, locked spacer is attached on the outer side surface of locking nut, and described outer claw is bumped in the keyway of lace nut, described interior claw is bumped in the elongated slot of hub carrier.The arranged outside jump ring of locked spacer, described jump ring is bumped in the jump-ring slot of hub carrier.
Described locked spacer is two, and two locked spacers are installed in respectively the diverse location on the hub carrier outer side surface.
The utility model beneficial effect is:
1, locked spacer is installed firmly, prevents that locking nut is loosening under long-time alternate load effect, and anti-loosing effect is good.
2, locking nut and locked spacer are reusable.
3, installation, maintenance is convenient, fast, high working efficiency.
4, rational in infrastructure, fabricating cost is low, is convenient to promote the use of.
