Abstract
The utility model discloses a kind of 5 tons of loading wheel side round nut anti-loose structures, including internal gear, round nut, locked spacer, sun gear, circlip, semiaxis, locked spacer claw, round nut open slot, internal gear groove, bearing and support shaft；Internal gear is mounted in support shaft, and internal gear left end is equipped with round nut, and right end installs bearing；Internal gear is equipped with internal gear groove；Round nut is equipped with round nut open slot；Locked spacer is equipped with locked spacer claw, and the locked spacer claw of the locked spacer is embedded in round nut open slot and internal gear groove, to play anti-loose effect；The left end of locked spacer is sun gear, right end is support shaft, and the internal spline and semiaxis in sun gear are limited with the circlip of merga pass left end of sun wheel.The utility model is simple and compact for structure, production is low with maintenance cost, safe and reliable, solve the problems, such as in the prior art because round nut is easily loosened and exited damage bearing and gear and because hex screw easily by rounding caused by maintenance difficulty it is big.
Description
Technical field
The utility model relates to a kind of loading machine drive axle wheel edge structures, and in particular to 5 tons of loading machine drive axle wheel edge circles
Nut locking structure.
Background technique
Currently, domestic mainstream loading machine drive axle wheel side reducer is all made of NGW structure, for transmitting high torque,
The internal spline of internal gear and the external splines of support shaft cooperate, and one end is bonded bearing, and the other end is locked in support shaft by round nut.
Its internal gear locking mechanism of 5 tons of loading machine drive axle wheels side reducer in the prior art uses after round nut is locked by two
Screw is locked to internal gear and carries out locking, which has following several disadvantages: 1., using screw by round nut being locked to internal tooth
On wheel, easily loosens when operation and cause round nut to exit so as to cause bearing and gear failure failure；2., the structure is because of interior hexagonal spiral shell
Nail is smaller, and easily occurring hexagonal in its head in maintenance it is difficult can only to increase maintenance by welding or cutting dismantling by rounding
Degree.
Summary of the invention
The purpose of the utility model is to overcome drawbacks described above, provide it is a kind of it is simple and compact for structure, production is low with maintenance cost,
5 tons of safe and reliable loading wheel side round nut anti-loose structures, to solve to exit because round nut easily loosens in the prior art
And damage bearing and gear and the problem easily big by maintenance difficulty caused by rounding because of hex screw.
In order to achieve the above object, 5 tons of loading wheel side round nut anti-loose structures of the utility model include internal gear, circle spiral shell
Mother, locked spacer, sun gear, circlip, semiaxis, locked spacer claw, round nut open slot, internal gear groove, bearing and support
Axis；The support shaft is mounted in support shaft as fixing piece, the internal gear, and internal gear left end is equipped with round nut, right end
Bearing is installed；The internal gear is equipped with internal gear groove；The round nut is equipped with round nut open slot；It is set on the locked spacer
There is locked spacer claw, the locked spacer claw of the locked spacer is embedded in round nut open slot and internal gear groove, to rise
To anti-loose effect；The left end of the locked spacer is sun gear, right end is support shaft, internal spline and semiaxis cooperation in sun gear
And it is limited by the circlip of left end of sun wheel.
Above-mentioned 5 tons of loadings wheel side round nut anti-loose structure is by redesigning round nut, internal gear and locked spacer knot
Structure, round nut outer ring are equipped with open slot, and internal gear is equipped with groove, while locked spacer is set there are two claw, is had beneficial below
Effect:
1., this 5 tons loading wheel side round nut anti-loose structures locked without screw, but it is direct with the claw of locked spacer
It is assembled in the open slot of round nut outer ring and the groove of internal gear, while locked spacer end face is limited by sun gear；This
Outside, locked spacer is handled using tufftride, guarantees wearability, it is ensured that reliability.
2., the assembly of this 5 tons loading wheel side round nut anti-loose structures it is simple and convenient, high-efficient, it is easy to maintenance.
Detailed description of the invention

Specific embodiment
With reference to the accompanying drawings and detailed description to 5 tons of loading wheel side round nut anti-loose structures of the utility model make into
One step is described in detail.
Shown in Fig. 1-4,5 tons of loading wheel side round nut anti-loose structures of the utility model include internal gear 1, round nut 2, stop
Mobile gasket 3, sun gear 4, circlip 5, semiaxis 6, locked spacer claw 7, round nut open slot 8, internal gear groove 9,10 and of bearing
Support shaft 11；The support shaft 11 is used as fixing piece, and internal gear 1 is mounted in support shaft 11 when work, the installation of 1 left end of internal gear
There is round nut 2, right end installs bearing 10, and wherein internal gear 1 is equipped with internal gear groove 9, and round nut 2 is equipped with round nut open slot 8；
Locked spacer 3 is equipped with locked spacer claw 7；When installation, guarantee that the locked spacer claw 7 of locked spacer 3 is embedded in round nut and opens
In mouth slot 8 and internal gear groove 9, to play anti-loose effect；The left end of locked spacer 3 is sun gear 4, right end is support shaft
11,4 internal spline and semiaxis 6 are limited with the circlip 5 of 4 left end of merga pass sun gear in sun gear.
By the structure of redesign round nut 2, internal gear 1 and locked spacer 3, round nut 2 is equipped with to be justified the utility model
Nut open slot 8, internal gear 1 are equipped with internal gear groove 9, and locked spacer 3 is equipped with locked spacer claw 7 at two, assemble stop
Locked spacer claw 7 is directly fitted to the round nut open slot 8 of 2 outer ring of round nut and the internal gear groove of internal gear 1 when gasket 3
In 9, while 3 end face of locked spacer is limited by sun gear 4, and locked spacer 3 is handled using tufftride, wear-resisting to guarantee
Property, it is ensured that reliability.Total assembly is simple and convenient, and assembly efficiency is high, and maintainability is good, increases enterprise income.
