Abstract
The utility model discloses a coil spring type torque limiter which adopts the structure of a compression spring to improve the working efficiency and effectively protect a lead screw from overloading. The coil spring type torque limiter includes a moment input shaft and an output shaft, wherein the moment input shaft comprises a shaft, a locking nut, a U-shaped corrugated pipe, a key, a gland, a retainer component, a spring seat, the compression spring, a compression ring, set screws, etc.; ball seats are arranged on the radial circumference of the retainer component at different angles, and balls are arranged in the ball seats; the output shaft is a positioning sleeve; and the positioning sleeve, the balls, the shaft and the compression spring are clamped through the locking nut, so that the torque can be transmitted from the input shaft to the output shaft (the positioning sleeve) through the transmission of the frictional force generated by the balls. As a mating component of Europe-manufactured viscose filters on the domestic production line, the coil spring type torque limiter has the characteristics of high efficiency and rapid response, can effectively protect the lead screw from being damaged by overloading, and can be widely used in the filtering of basic viscose solution in the chemical fiber industry.
Description
Technical field
The utility model relates to the filter field of mechanical technique, and definite says, it is that a kind of inside is made up of compression spring assembly U type bellows, is applied in the ring spring formula torque limiter on the viscose filtration machine.
Background technology
During viscose rayon is produced; Usually adopt the sheet frame filter to filter viscose glue, flame filter press mainly fixedly form by thrust plate by filter plate, the movable filter plate of pressure strip, filter plate and filter frame, crossbeam band iron frame, filter medium filter cloth or filter paper etc., hold down gag, collecting tank etc.What chemical fiber factory generally used now is KK type filter, and a kind of cylindrical shape automatic fitration equipment filters viscose glue.The viscose filtration machine is one of key equipment of viscose glue stoste, and the viscose glue after it will filter is transported on the spinning-drawing machine.In a single day the viscose filtration machine breaks down and can cause whole production line to be stopped; So; In the transmission system of viscose filtration machine, need be provided with the torque limiter of overload protective function specially; Prevent that on the one hand power shaft from will transship moment of torsion and passing to output shaft, cause leading screw to fracture and damage piston ring, reduce hand labor intensity, lifting means automatization level on the other hand, enhance productivity.
The main deficiency of flame filter press is exactly:
1, manual work needs block-by-block pulling filter plate to unload filter cake, and cleaning simultaneously is bonded at the filter residue at sealing surface place, and preventing that filter residue is clipped in influences sealing property on the sealing surface, produces the seepage phenomenon, has increased artificial labour intensity virtually.
2, because too much manually-operated participation, the operation that makes filter can only be to be interrupted and discontinuous, the automatization level that has reduced production line with cause low production efficiency.
3, manually-operated too much participation forces the workman directly to contact with chemicals, has increased the possibility that accident occurs.
Summary of the invention
The utility model is that its objective is provides a kind of torque limiter that can play overload protective function to leading screw to the technological improvement of existing viscose filtration machine.The pre-fastening moment of appropriate setting torque limiter is extremely important, if the pre-fastening moment of torque limiter is excessive, will not have the effect of protection leading screw so; If the pre-fastening moment of torque limiter is too small, do not reach the required torsional moment of leading screw so, the revolution that the ratio of revolutions of leading screw is set is low, thus the not enough spinning quality that has influence on of filtration yield.Ring spring torque limiter adjustment pre-fastening moment can be realized through adjusting lock nut and holding screw.
The purpose of the utility model is to realize like this.Ring spring formula torque limiter, it is made up of moment power shaft and output shaft, and wherein the moment power shaft comprises axle, locking nut, lock washer, U type bellows, key, gland, retainer assembly, spring base, compression spring, pressure ring and holding screw composition; The retainer assembly is provided with ball base according to different angles on radial circumference, the inner ball of placing is aspect axle axial; At first put into the retainer assembly, put into gland then, have the U type bellows of compression spring, spring base and pressure ring to put in inciting somebody to action afterwards; Regulate pre-fastening moment with locking nut and holding screw; Fix and the axle rotation that fuses with lock washer, output shaft is a positioning sleeve; Therebetween; Add ball in the retainer assembly between positioning sleeve and axle, locking nut clamps positioning sleeve, ball, axle and compression spring, and the moment of torsion that is come by the power shaft transmission like this passes to the output shaft positioning sleeve through the frictional force that the transmission ball produces.
The utility model has the advantages that: as the matching component of european version viscose filtration machine on the domestic production line; Ring spring formula torque limiter has the efficient height, leading screw soon, is effectively protected in reaction; Make it avoid transshipping the characteristics of the damage that causes, thereby guaranteed the operating efficiency of complete machine.

Fig. 2 is a ring spring cutaway view among Fig. 1.
The specific embodiment
The utility model is made up of moment power shaft and output shaft, and wherein the moment power shaft comprises axle 1, locking nut 2, lock washer 3, U type bellows 4, key 5, gland 6, retainer assembly 7, spring base 9, compression spring 10, pressure ring 11 and holding screw 12 compositions, and the retainer assembly is provided with ball base according to different angles on radial circumference; The inner ball of placing aspect axle 1 axial, is at first put into retainer assembly 7; Put into gland 6 then; Afterwards will in have the U type bellows 4 of compression spring 10, spring base 9 and pressure ring 11 to put into, regulate pre-fastening moments with locking nut 2 and holding screw 12, fix with lock washer 3; With axle 1 rotation that fuses; Output shaft is a positioning sleeve 8,, adds ball in the retainer assembly between positioning sleeve 8 and axle 1 therebetween; Locking nut clamps positioning sleeve 8, ball, axle 1 and compression spring 10, and the moment of torsion that is come by the power shaft transmission like this passes to output shaft positioning sleeve 8 through the frictional force that the transmission ball produces.
Under effect, be static between positioning sleeve 8 and the axle 1 under the normal condition by the moment of friction of ball transmission; When motor load is excessive; Motor rotational resistance square has surpassed the moment of friction that the maximum static friction force that produced by pretightning force can provide, and at this moment ball and ball base disengaging take place to slide each other between positioning sleeve 8 and the axle 1; And then under the effect of compression spring 10, impel axle 1 and positioning sleeve 8 to break off; The revolution of leading screw reduces or stops not change like this, and to bear moment of torsion excessive thereby avoid occurring leading screw, and make leading screw or piston ring that the serious consequence of fracture take place.
