Abstract
The utility model discloses a connection component of a drafting device which can regulate the center distance of shafts or regulate the drive ratio of shafts with stable transmission and simple structure. The utility model comprises a constant angular velocity universal coupling connected with the output shaft of the draft change gear and a constant angular velocity universal coupling connected with a drafting roller. The two constant angular velocity universal couplings are connected through a connecting rod. The articular positions of the couplings adopt three steel balls to obtain the connection of an outer shell and an inner joint. Compared with the prior art, the utility model has the advantages of good working order, stable transmission and simple structure. The utility model can effectively decrease the vibration generated when the machine operates. The forming quality of the sliver forming lap is good. The utility model used as a connection component of a drafting device of a sliver doubling machine has maximum economic value.
Description
One, technical field
The utility model relates to a kind of textile machine parts, specifically a kind of attaching parts that are used for bar and roll up drafting system.
Two, background technology
In textile machine, the annexation of draft change gear output shaft and drawing rollers is extremely important.Because drawing-off drive mechanism compactness, change gear is more, under the constant condition of output shaft fixed-site, requires the front and back position of drawing rollers must can do suitable adjusting, and requires stable drive between them.On known similar machine, most synchronous pulley or carrier gears of adopting connect draft change gear output shaft and drawing rollers, under specific gearratio, regulate gearratio by synchronous pulley or carrier gear.In order to satisfy centre-to-centre spacing and gearratio related request, and guarantee to regulate at any time, transmission mechanism designs comparatively complicatedly, correlated parts is more, it is big to take up space, and gear can only adopt the open type transmission, and perhaps the volume of its gear-box and appearance and size are bigger, and because each is axially for being rigidly connected, during machine run, transmission position and vibration meeting mutual superposition, the mutual interference mutually of carrying out the generation of action position, working order is poor, transmission is not steady, has had a strong impact on the forming quality of bar and volume.
Three, summary of the invention
The purpose of this utility model provides the attaching parts of good, the simple in structure drafting system of a kind of working order.
The purpose of this utility model is achieved like this: a kind of attaching parts of drafting system, it is characterized in that: it comprises the angular speed universal coupling that connects the draft change gear output shaft, angular speed universal coupling and the connecting rod that connects drawing rollers, and described two angular speed universal couplings connect by connecting rod.
Described angular speed universal coupling comprises shell head, nipple and steel ball; Circumferentially be provided with ring groove at the shell head, one end of nipple extend in the ring groove and is provided with the circular hole that matches with steel ball, ring groove and circular hole opposite position are provided with the circular arc suitable with steel ball, and nipple is connected with the shell head by placing the steel ball in the circular hole; On the shell head, be provided with the back-up ring that prevents that nipple and steel ball from coming off.The nipple of two Hooks coupling universal couplings is connected with connecting rod by connecting pin, is used for transmitting moment of torsion.
For preventing that the lubricated greasy dirt of steel ball from dying, prolong the service life of shaft coupling, between shell head and nipple, be with flexible boot.
In the utility model, the shell head of angular speed universal coupling all can be angled with connecting rod at arbitrary orientation, and two end housing head axis can produce a little skew, but the connection length between two shaft couplings remains unchanged.
Compared with prior art, the utility model adopts angular speed universal coupling to connect draft change gear output shaft and drawing rollers, and it is simple in structure, independent, irrelevant mutually separately, the influence of regulating shaft centre-to-centre spacing or adjusting gearratio; Simultaneously, the volume and the appearance and size of transmission position gear-box are less, gear-box can be bath lubrication, working order is good, after adopting the utility model to connect draft change gear output shaft and drawing rollers, stable drive, the vibration that has produced when having reduced machine works effectively, the forming quality of bar and volume is good.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is a kind of working state figure of the utility model.
Five, the specific embodiment
A kind of attaching parts of drafting system described in the utility model, it comprises that the angular speed universal coupling 1 that connects draft change gear output shaft 11, the angular speed universal coupling 2 that connects drawing rollers 12 and 3, two angular speed universal couplings of connecting rod 1,2 connect by connecting rod 3.Angular speed universal coupling 1 comprises shell head 4, nipple 5 and steel ball 6; Circumferentially be provided with ring groove 7 at shell head 4, one end of nipple 5 extend in the ring groove 7, circumferentially evenly be provided with three circular holes that match with steel ball 6 sizes on the position in extending into ring groove 7, ring groove 7 and circular hole opposite position are provided with the circular arc suitable with steel ball 6, steel ball 6 is packed in the circular hole of nipple 5, and steel ball 6 is aimed at arc position on the ring grooves 7 at circumferencial direction, be inserted in together then in the ring groove 7 of shell head 4, nipple 5 is connected with shell head 4 by placing the steel ball 6 in the circular hole; On shell head 4, be provided with the back-up ring 8 that prevents that nipple 5 and steel ball 6 from coming off.The nipple of Hooks coupling universal coupling 1 is connected with connecting rod 3 by connecting pin 9.In the utility model, steel ball is the key component of shaft coupling, is used for transmitting moment of torsion, and each Hooks coupling universal coupling is equipped with three steel balls.The nipple of two Hooks coupling universal couplings all is connected with connecting rod by connecting pin, is used for transmitting moment of torsion.For preventing that steel ball 6 lubricated greasy dirts from dying, prolong the service life of shaft coupling, between shell head 4 and nipple 5, be with flexible boot 10.
In the utility model, the angular speed universal coupling 1 that connects draft change gear output shaft 11 adopts identical structure with the angular speed universal coupling 2 that is connected drawing rollers 12.Joint part at shaft coupling adopts three steel balls to realize being connected of shell head and nipple, because steel ball can slide in the shell head vertically on a small quantity, in transmission process, the shell head can be angled at arbitrary orientation and nipple, make the power transmission shaft at shaft coupling two ends can be not the steady transmission of constant angular velocity on straight line, and the two-part mechanical oscillation that connect are not disturbed mutually.Like this, under the situation that the connection length of shaft coupling remains unchanged, two end housing head axis can be offset on a small quantity, satisfy the drawing rollers front and back position and adjust requirement, guarantee the forming quality of bar and volume.
