Abstract
The utility model discloses an arc spreading roller coupler. The arc spreading roller coupler comprises an inner sleeve, wherein the inner sleeve is arranged on a shaft; a first coupler is arranged on a bearing, 8 to 12 holes are formed on one end face of the first coupler, bushes are arranged in the holes, 8 to 12 holes are formed on one end face of a second coupler and in one-to-one correspondence to the holes on the end face of the first coupler, one end of an elastic pin is arranged in each hole of the second coupler in an interference fit mode, and the other end of the elastic pin is arranged in the inner hole of each bush on the first coupler in a clearance fit mode, so that two steel sleeves are connected; and the bearing is provided with a stop ring. When an arc roller works, the steel sleeves are driven to rotate by the elastic pins, and the bushes are elastic pieces, so that collision impact between the elastic pins and the bushes is very low at the stage of starting and stopping the arc roller, and the high-speed starting, stopping and operation of the arc roller can be ensured by the coupler. The arc spreading roller coupler has a simple structure, is reliable in performance and can reliably drive each steel sleeve of the arc roller to rotate, accelerate, start and stop at high speed.
Description
Technical field
The utility model relates to the high speed paper machine technical field, is specifically related to a kind of curved bar spreader shaft coupling.
Background technology
Curved bar spreader is the vitals in the paper making equipment, and main effect is to unfold the paper web that moves in the paper machine, prevents wrinkling.
Curved bar spreader is on the axle of a bending of not rotating, to load onto the more piece steel bushing, and on cambered axle, steel bushing is rotatable by bearings for every joint steel bushing.Because crooked geometry forms the direction of an indent and evagination, paper web is got into by concave surface, through the frictional force drive bowed roller rotation on surface.Need not be in transmission connection between the every joint steel bushing of early stage bowed roller.
The Modern High-Speed paper machine speed of a motor vehicle is high, quickens soon, only depends on the frictional force on paper web and roll body surface can not drive the curved bar spreader rotation, need add auxiliary transmission in the one or both ends of bowed roller, drives the steel bushing rotation of bowed roller end.The steel bushing of end drives other steel bushing rotations.This just requires between the steel bushing flexible jockey must be installed on the bowed roller, and rotation torque is passed to other steel bushing from the first segment steel bushing of end.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of the utility model is to provide a kind of curved bar spreader shaft coupling, and is simple in structure, dependable performance.
In order to achieve the above object, the technical scheme of the utility model employing is:
A kind of curved bar spreader shaft coupling, cover 6 in comprising, interior cover 6 are contained on the axle 1; First shaft coupling 5 is contained on the bearing 4, and end face has the 8-12 hole on it, and edge cover 7 is housed in the hole; An end face of second shaft coupling 9 also has the 8-12 hole, and corresponding one by one with the hole on first shaft coupling, 5 end faces, and resilient key 8 one end interference are contained in the hole of second shaft coupling 9; The edge that one splaying is contained on first shaft coupling 5 overlaps in 7 endoporus, and two joint steel bushings 2 are coupled together, and bearing 4 is provided with baffle ring 3.
The material of described edge cover 7 is rubber or nylon.
The beneficial effect of the utility model is: simple in structure, dependable performance can reliably drive the every joint steel bushing of bowed roller and run up and start and stop with high acceleration.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
With reference to Fig. 1, a kind of curved bar spreader shaft coupling, cover 6 in comprising, interior cover 6 are contained on the axle 1; Axle 1 is crooked, and first shaft coupling 5 is contained on the bearing 4, and end face has the 8-12 hole on it, and edge cover 7 is housed in the hole; The material of edge cover 7 is rubber or nylon, has certain elasticity, and an end face of second shaft coupling 9 also has the 8-12 hole, and corresponding one by one with the hole on first shaft coupling, 5 end faces; Resilient key 8 one end interference are contained in the hole of second shaft coupling 9, and the edge that a splaying is contained on first shaft coupling 5 overlaps in 7 endoporus, and two joint steel bushings 2 are coupled together; Bearing 4 is provided with baffle ring 3, and baffle ring 3 is used for sealed bearing 4, prevents that the lubricating grease in the bearing 4 from revealing.
The operation principle of the utility model is:
The bowed roller that has cambered axle has a male and fomale(M&F) on geometry, this male and fomale(M&F) is the basis that paper web is able to unfold.If paper web gets into concave surface, gets into convex surface through roll surface; Paper web will be unfolded, and during bowed roller work, utilizes resilient key 8 to drive and respectively saves the steel bushing rotation; Because edge cover 8 is elastic components; So in the bowed roller start and stop stage, the collision impact between resilient key 8 and the edge cover 7 can be very little, shaft coupling just can guarantee the start and stop of bowed roller high speed and run up.
