Abstract
The utility model relates to an all-plastic tape drive pulley for the spindle transmission system of a spinningframe in textile machinery. The drive pulley is an all-plastic tape drive pulley system composed of a cylindrical core hole, three keys distributed on the wall of the core hole in an equal radian, three contraction joints distributed on a fastening lining in an equal radian, three keyways distributed on the fastening lining in an equal radian and plastic locking cap nuts. Since the utility model adopts the key-keyway connection mode, the phenomenon of rotational loss of the drive pulley caused by the relative motion between the drive pulley and the fastening lining is guaranteed not to happen; the light weight is favorable for saving energy.
Description
This is practical to be the overall plastic rolling disk of using about weaving mechanism fine spining machine main axis transmission system.
What present homemade fine spining machine main axis transmission system generally adopted is metal rolling disk or metal roller.Because every fine spining machine need be installed 100 cover rolling disks, the heavy 1500g of metal rolling disk one cover, labour intensity was big when the workman installed, and the equipment starting torque is big, for guaranteeing dynamic balancing, will fix the footpath of each rolling disk when the metal rolling disk is installed and jump direction.The metal rolling disk is processed by sheet iron in addition, can noise take place the generation vibration under the rotation at a high speed.The metal rolling disk is reinstalled through short-term at every turn and is used the rear section tightly fixed liner loosening phenomenon can occur, rolling disk is thrown switch cause the twist of yarn to descend.Therefore to make regular check on the metal rolling disk of new installation, till tightly fixed liner no longer takes place to become flexible.It is tightly fixed liner that Switzerland's Rieter (Rieter) company has used instead on the G5/1 fine spining machine with engineering plastics to the disk body stainless steel, during injection moulding lining and disk body are combined as a whole, lock onto plastics rolling disk on the turning cylinder with the metal jackscrew, because this rolling disk has used stainless steel to do tightly fixed liner, make to cost an arm and a leg, also increased the weight of plastics rolling disks simultaneously.Inconvenience when jackscrew is installed at some position in addition, easy loose or dislocation during running.
The purpose of this utility model is cylinder centre of form hole of design, and hole wall has three plastics rolling disks that wait radian distribution key heart hole to be furnished with tightly fixed liner, and its overall weight is light, and cost is low, and noise is little, and is energy-conservation, non-corroding, and locking mechanism is reasonable.A complete set of weight is 500g only.
The plastics rolling disk of the utility model design is to have three cylinder centre of form holes of waiting radian distribution key by one, with a tightly fixed liner that has certain dimension, and tightly fixed liner has three shrinkage joints, and have with cylinder centre of form hole on the keyway that matches of radian distribution keys such as three, axially be threaded at the keyway position and be equipped with plastics locking nut block and become overall plastic rolling disk system.
The technical solution of the utility model accompanying drawings is as follows:
Accompanying drawing 1 is the warp-wise profile of plastics rolling disk system.(1) rolling disk; (2) tightly fixed liner; (3) lock nut; (4) rolling disk heart hole connecting key; (8) spindle band groove.Accompanying drawing 2 is tightly fixed liner schematic diagrames, (5) keyway, (6) shrinkage joint, (7) screw thread.Rolling disk among Fig. 1 (1), tightly fixed liner (2), lock nut (3) is all used the modified engineered plastic injection moulding.Rolling disk (1) middle part is in the form of annular discs, and there is the spindle band groove (8) parallel with the mechanical rotation axle at the rolling disk edge.There is a cylinder centre of form hole at the center, hole wall have three be used for and tightly fixed liner (2) on the key (4) that matches of three keyways (5), tightly fixed liner (2) is gone up and axially is threaded (7) in keyway (5) position, and tightly fixed liner (2) has three shrinkage joints (6), and the outside does not have the screw thread place and prolongs certain taper is axially arranged.Lock nut (3) is connected with tightly fixed liner (2) by screw thread (7), by screwing nut a whole set of rolling disk system closely is connected with the mechanical rotation axle.
The utility model has been owing to adopted key-groove connecting mode, guaranteed can relative motion not take place between rolling disk and the tightly fixed liner and causes rolling disk the phenomenon that throws switch to occur.Brought convenience for thus screwing of nut, again because loosening phenomenon of rolling disk and corrosion phenomena can not appear when making the complete machine running in the characteristic of material, the alleviating and help energy-conservation of overall weight.And the tool that helps weaving develops to light bodyization and high speed direction.With the metal rolling disk than technically with on the serviceability very much progress being arranged all undoubtedly.
Claims (1)
1, a kind of textile machinery plastics rolling disk, its edge has the spindle band groove parallel with the mechanical rotation axle, feature of the present utility model is that rolling disk (1) is to have three cylinder centre of form holes of waiting radian distribution key (4) by one, a tightly fixed liner (2) that has certain taper, tightly fixed liner (2) has three shrinkage joints (6), and have with cylinder centre of form hole on the keyway (5) that matches of radian distribution keys (4) such as three, axially be threaded (7) at keyway (5) position, cylinder centre of form hole and tightly fixed liner are equipped with the overall plastic structure rolling disk of plastics lock nut (3) composition.
