Abstract
A connecting structure of a material throwing roller power transmission shaft includes a speed reducer and a material throwing roller shaft, wherein the material throwing roller shaft is in transmission connection with a hollow output shaft of the speed reducer and is fixed to a gland through a holding-down bolt; conical tension sleeves are arranged between the hollow output shaft of the speed reducer and the material throwing roller shaft; conical surfaces matched with the conical tension sleeves are arranged on the inner wall of the hollow output shaft hole of the speed reducer; and the conical tension sleeves for replacing keys are additionally arranged on the original shaft. The connecting structure of the material throwing roller power transmission shaft shortens the maintenance and improvement time, reduces shaft abrasion, prolongs the service life, and reduces the maintenance cost of enterprises.
Description
Technical field
The utility model relates to the Fibreboard Production manufacturing field of equipment, a kind of specifically material casting roller power transmission Axile connection structure.
Background technique
All to use machinery in a large number in the general manufacturing enterprise; Machinery generally adopts motor, speed reducer etc. to move through driving component; And between speed reducer and driving component, driving component and the transmission shaft because wearing and tearing in various degree often appear in mutual transmitting torque, finally cause the machinery component to lose efficacy; Thereby influence ordinary production, increased the device maintenance cost simultaneously.Special, in mdf production line, in order in the operation of mating formation of production line, wood fibre evenly to be broken up; Used more material casting roller, wherein most of material casting roller is directly driven through hollow output shaft by speed reducer, behind the process long-play; Output shaft and material casting roller cooperation place (key) serious wear; Cause the speed reducer operation to rock, wearing and tearing are further aggravation also, because production task is tight, the material casting roller is difficult to dismounting and change; And the scene is difficult to repair, so affect greatly to ordinary production.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of material casting roller power transmission Axile connection structure.
A kind of material casting roller power transmission Axile connection structure comprises speed reducer, material casting roll shaft, and the hollow output shaft of said material casting roll shaft and said speed reducer is in transmission connection, and fixes through hold-down bolt and gland; Be provided with taper tensioning cover between the hollow output shaft of said speed reducer and the said material casting roll shaft.
Said taper tensioning cover is two, is separately positioned on the two end part of said speed reducer hollow output shaft.
Having the conical surface that cooperates with said taper tensioning cover on the said speed reducer hollow output shaft shaft hole inner wall increases taper tensioning cover replacement key on original axle, the maintenance and renovation time is short, has reduced the wearing and tearing of axle, prolongs its working life, reduces enterprise's maintenance cost.
Description of drawings
Fig. 1 is a kind of material casting roller of the utility model power transmission Axile connection structure structural representation;
Wherein: 1, material casting roll shaft; 2, speed reducer; 3, speed reducer hollow output shaft; 4, taper tensioning cover.
Embodiment
In order fully to understand the technical spirit and the beneficial effect of the utility model; With combining accompanying drawing below the embodiment of the utility model is described in detail; But the description to embodiment is not the restriction to technological scheme, anyly makes form but not the variation of essence all should be regarded as the protection domain of the utility model according to the utility model design.
Because the material casting roller is difficult to dismounting, can not repair through the mode of field maintenance again the axle of wearing and tearing, and the speed reducer dismounting is relatively easy; So just can only cooperate and carry out appropriate reconstruction to present transmission; The special taper tensioning cover 4 of making 2 openings also carries out appropriate reconstruction to speed reducer 2 hollow output shafts 3 simultaneously, makes the taper tensioning overlap 4 endoporus and cooperates with hollow output shaft 3; And male cone (strobilus masculinus) cooperates with the inner conical surface of speed reducer quill shaft, after assembling again the hold-down bolt through end face carry out tensioning.
