Furtherly, cydariform toe joint axle transition transmission structure still include connection pad, end cover, and connection pad and end cover sticis both ends face about transition tooth cover respectively, and the end cover passes through the bolt -up on the terminal surface of axle sleeve. The utility model discloses cydariform toe joint axle transition transmission structure, its cydariform tooth internal tooth part sets up to be put in at the transition tooth, when the internal tooth lost efficacy, the tooth that only need will pass through overlap more change can, need not to change whole axle sleeve, the spiale maintenance cost has significantly reduced.

Description

A kind of new drum Gear Couplings' transition drive mechanism

Technical field

This utility model is related to the main transmission shaft structure of cold mill complex and in particular to drum Gear Couplings' transition drive mechanism.

Background technology

The final drive shaft of cold mill complex is the crucial drive apparatus in whole milling equipment, and existing steel rolling process requires transmission Axle possesses high rotating speed, high-precision characteristic, so usually selecting drum-shaped tooth type spindle as mill's main drive shaft.

At present, because of factors such as space restrictions, cold rolling drum Gear Couplings', adopt dry oil lubrication form more.Cold rolling power transmission shaft work Rotating speed is high, and in operating, teeth portion produces amount of heat, leads to the barreled tooth flank flank of tooth phenomenon such as spot corrosion, gluing, lose flesh so that teeth portion Lost efficacy.During existing drum Gear Couplings' design, barreled tooth flank inner toothed portion and axle sleeve are integrated, once teeth portion lost efficacy, then Whole axle sleeve need to be changed, considerably increase spindle maintenance cost.

Utility model content

Problem to be solved in the utility model is to provide a kind of drum Gear Couplings' transition drive mechanism, and it solves existing Spindle teeth portion lost efficacy and must change the problem of axle sleeve, greatly reduce spindle maintenance cost.

A kind of this utility model drum Gear Couplings' transition drive mechanism, it includes axle sleeve, transition tooth set, outside transition tooth set Circle is coupled with the internal spline on axle sleeve for external splines, and the endoporus of transition tooth set is barreled tooth flank internal tooth, passes through cydariform with externality shaft Tooth engages.

Further, drum Gear Couplings' transition drive mechanism also includes terminal pad, end cap, and terminal pad and end cap press respectively In the left and right both ends of the surface of transition tooth set, end cap is fastened by bolts on the end face of axle sleeve.

Further, groove at least two on the flange face of terminal pad, groove radial depth is less than the interior of transition tooth set Tooth path, the vertical position of this groove is alignd with two oil filler points on sleeve outer circle.

This utility model drum Gear Couplings' transition drive mechanism, its barreled tooth flank inner toothed portion is arranged on transition tooth and puts, when It is only necessary to replace transition tooth set when internal tooth lost efficacy, whole axle sleeve need not be changed, greatly reduce spindle and safeguard into This.

Brief description

Fig. 1 is the structural representation of this utility model drum Gear Couplings' transition drive mechanism；

Fig. 2 is the enlarged diagram at X in Fig. 1；

Fig. 3 is the schematic diagram of transition tooth set.

Specific embodiment

Knowable to accompanying drawing, a kind of new drum Gear Couplings' transition drive mechanism of this utility model, it includes axle sleeve 1, mistake Cross tooth set 3, the cylindrical of transition tooth set 3 is coupled with the internal spline on axle sleeve 1 for external splines, the endoporus of transition tooth set 3 is barreled tooth flank Internal tooth, is engaged by barreled tooth flank with externality shaft 5.

As a kind of optimal way of the present utility model, drum Gear Couplings' transition drive mechanism also includes terminal pad 2, end cap 4, terminal pad 2 and end cap 4 are pressed on the left and right both ends of the surface of transition tooth set 3 respectively, and end cap 4 is fastened by bolts the end in axle sleeve 1 On face.Terminal pad 2 and end cap 4 achieve the axially position that transition tooth covers 3 and end cap 4.

As another optimal way of the present utility model, at least two on the flange face of terminal pad 2 at groove, groove footpath It is less than the internal tooth path of transition tooth set 3 to depth, two oil filler points on the vertical position of this groove is cylindrical with axle sleeve 1 align. The groove radial depth of terminal pad 2 is less than the internal tooth path of transition tooth set 3 it is ensured that terminal pad 2 compresses the same of transition tooth set 3 When, passage is provided for oiling by groove.During oiling, from axle sleeve 1 oil filler point oiling, enter in terminal pad 2 flange groove, stream Enter in the cavity between axle sleeve 1 and externality shaft 5, teeth portion is lubricated.I.e. the groove design in terminal pad 2 ensure that in spindle Portion fully can fill lubricating oil, meets teeth portion lubrication needs.

Wherein, transition tooth set 3 and axle sleeve 1 are stationary fit.So, it is geo-stationary between transition tooth set 3 and axle sleeve 1, Sliding will not be produced.

This utility model drum Gear Couplings' transition drive mechanism both ensure that the requirement of spindle transmitting torque, achieved again Cross the quick-replaceable between tooth set 3 and axle sleeve 1, in the case of not affecting spindle performance, substantially prolongs the use longevity of axle sleeve 1 Life, decreases because barreled tooth flank lost efficacy and changes the cost of disabling elements, thus reducing the maintenance cost of spindle.

This utility model is not limited in cold mill complex drum Gear Couplings', can be also widely applied to other and passes through cydariform On the equipment that tooth connects.
