Description
One, technical field
The utility model belongs to a kind of textile machine parts, specifically a kind of coupling arrangement that is used between draw frame and lap machine combined drawing-off gearbox and the drawing rollers.
Two, background technology
The drawing-off transmission of draw frame and lap machine combined is very big to the web quality influence, requires each drawing rollers running during work steadily, and driving shaft and driven shaft turn round synchronously; For adapting to different cotton spinning parameters, all need make in the speed ratio between drawing rollers, the work of spacing and correspondingly adjust and change, so that connecting between drawing-off output shaft of gear-box and the corresponding drawing rollers produces axial and drift angle displacement.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 a kind of simple in structure, drawing-off coupling arrangement of being convenient to make, can realize the constant angular velocity transmission.
The purpose of this utility model is achieved like this: a kind of drawing-off coupling arrangement, it is characterized in that: it comprises the movable shaft coupling of rigidity, jackshaft and the movable shaft coupling of the rigidity that is connected drawing rollers that connects the drawing-off output shaft of gear-box, and two movable shaft couplings of rigidity connect by jackshaft.During work, drawing-off coupling arrangement one end connects with the drawing-off output shaft of gear-box by joint, the other end connects with drawing rollers by joint, rigidity movable shaft coupling in two ends connects by jackshaft, and possess coupling spindle to drift angle displacement request within the specific limits, and can realize the constant angular velocity transmission.
In the utility model, the movable shaft coupling of rigidity comprises shell head, nipple and ball; Be provided with the cylindrical longitudinal groove suitable at shell headpin shape inner surface with ball, outer surface is that the nipple of cydariform extend in the shell headpin shape inner surface, be provided with the locating hole that matches with ball on the cydariform face, nipple is connected with the shell head by placing the ball in the locating hole; On the shell head, be provided with the back-up ring that prevents that nipple and ball from coming off.
For making the nipple processing and manufacturing simple, the center of nipple is the through hole of cylindrical internal surface, in order to make ball radial dimension unanimity, is provided with mandrel in through hole.
In the utility model, for guaranteeing the device security running better, the nipple on both sides all is connected with jackshaft by resilient key, and both sides shell head is connected with drawing rollers with the drawing-off output shaft of gear-box by resilient key.When load was excessive, resilient key was cut off, and can prevent that machine is subjected to improper damage, shields.
In rotation process, shaft coupling adopts grease lubrication, is subjected to action of centrifugal force, and lubricating grease can be thrown out of, and influences service life; Foreign material such as the fiber of work-yard, dust also easily enter lubricating oil simultaneously, make lubrication failure.In the utility model, for preventing that lubricating oil runs off, for preventing that foreign material from entering lubricating oil, between shell head and nipple, be with flexible boot on the other hand on the one hand, can prolong the service life of shaft coupling like this.
The utility model is in transmission process, and torque is passed to the nipple (driven end) of shaft coupling by ball by the shell head (drive end) of shaft coupling.Because ball can move axially in the arc groove of shell head, the nipple appearance is a cydariform, and the ball between shell head and the nipple has certain clearance in groove, and therefore, shaft coupling can obtain the comprehensive displacement of a certain amount of axial, drift angle.When the drift angle displacement took place two axial lines, the symmetry effect of axis two ends ball made drive end and driven end realize the transmission (ω 1=ω 2) of isogonism speed.
Compared with prior art, the utility model adopts two cover novel couplers, fully satisfied when the speed ratio between drawing rollers, spaced when changing, produced axially connecting between drawing-off output shaft of gear-box and the corresponding drawing rollers and the transmission needs the during displacement of drift angle.Its advantage is: simple in structure, and stable drive, the fluctuation of speed and the machinery of having eliminated drawing rollers effectively disturb, and make the web quality of draw frame and lap machine combined obtain guaranteeing reliably.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the movable coupler structure schematic diagram of rigidity described in the utility model.
Five, the specific embodiment
A kind of drawing-off coupling arrangement described in the utility model, comprise the movable shaft coupling 1 of rigidity, jackshaft 2 and the movable shaft coupling 3 of the rigidity that is connected drawing rollers that connect the drawing-off output shaft of gear-box, the movable shaft coupling 1 of rigidity is connected with the movable shaft coupling 3 of rigidity by jackshaft 2.
The movable shaft coupling 1 of rigidity is made up of shell head 4, nipple 5 and ball 6; The inner surface of shell head 4 is a cylinder shape groove, in cylinder shape groove, be provided with three with the suitable cylindrical longitudinal groove of ball 6.The outer surface of nipple 5 is a cydariform, and the center of nipple 5 is the through hole of cylindrical internal surface, during transmission, comes off for preventing ball 6, increases the intensity of nipple 5, is provided with mandrel 8 in through hole.On the cydariform face, be provided with three locating holes that match with ball 6, three balls are placed in the locating hole respectively, and extend in shell head 4 cylindrical internal surface, three balls are arranged in three cylindrical longitudinal grooves of shell head 4, and nipple 5 is connected with shell head 4 by ball 6; On shell head 4, be provided with the back-up ring 7 that prevents that nipple 5 and ball 6 from coming off.
For guaranteeing the device security running better, the nipple 5 on both sides all is connected with jackshaft 2 by resilient key 9, and both sides shell head 4 is connected with drawing rollers with the drawing-off output shaft of gear-box by resilient key 9.When load was excessive, resilient key 9 will be cut off, and can prevent that machine is subjected to improper damage.
During work, drawing-off coupling arrangement one end connects with the drawing-off output shaft of gear-box by joint, the other end connects with drawing rollers by joint, rigidity movable shaft coupling in two ends connects by jackshaft, in the transmission process, torque is passed to the nipple (driven end) of shaft coupling by ball by the shell head (drive end) of shaft coupling.Because ball can move axially in the arc groove of shell head, the nipple appearance is a cydariform, and the ball between shell head and the nipple has certain clearance in groove, and therefore, shaft coupling can obtain the comprehensive displacement of a certain amount of axial, drift angle.When the drift angle displacement took place two axial lines, the symmetry effect of axis two ends ball made drive end and driven end realize the transmission (ω 1=ω 2) of isogonism speed.Thereby the fluctuation of speed and the machinery that can eliminate drawing rollers effectively disturb, and make the web quality of draw frame and lap machine combined obtain guaranteeing reliably.
