Description
Technical field: the utility model relates to the hinge wheel in the linked transmission on the anchor clamps, particularly prevents the moment of torsion tyre chain wheel apparatus that hinge wheel skids in the process of transmitting torque.
Background technique: the sprocket wheel anchor clamps are a kind of so that its main kind of drive---sprocket driving is named.The kinematic chain of sprocket wheel anchor clamps is: the driven by motor minor sprocket, and minor sprocket drives hinge wheel by chain, and hinge wheel drives worm screw, and worm screw drives worm gear, the worm gear drives tooth bar, thus anchor clamps are opened and closed.Motor is a power source in the whole Transmitted chains, and motor is connected by key with minor sprocket; Minor sprocket is connected with hinge wheel by chain, hinge wheel and axle sleeve Spielpassung, and axle sleeve is connected by key with worm screw, and worm and worm wheel cooperatively interact, and worm gear and two and grip finger are that the tooth bar of one cooperates.Hinge wheel in the whole transmission is a driven wheel, and hinge wheel is given axle sleeve transmission of torque by shell fragment and friction plate, guarantees hinge wheel and axle sleeve molar behavior.Friction factor reduced after the on-the-spot resin friction plate that uses used a period of time, caused hinge wheel and axle sleeve that skidding often takes place.The attendant is by turning the gap of friction plate and sprocket wheel, axle sleeve down, and the elastic force that promptly increases shell fragment solves, but the elastic force of adjusting the stroke range of nut and shell fragment is all limited, and the friction factor of friction plate can't increase again; So more be friction plate, guarantee the normal operation of equipment by more renewing.This has just caused the consumption of spare part (resin bakelite friction plate) very big, has just damaged 70 a week; Influence the normal use of anchor clamps simultaneously, influenced the normal delivery of coil of strip.Chinese patent ZL02241859.8 discloses a kind of " load limiter ", this patent utilization spring compression friction plate carry-over moment, but patent does not solve the difficult problem that friction plate uses friction factor to reduce for a long time; Just reduce the frequency that friction plate is changed, fundamentally do not solved the big problem of friction plate consumption.
Summary of the invention: the purpose of this utility model provides a kind of moment of torsion tyre chain wheel apparatus that prevents that hinge wheel from skidding in the process of transmitting torque, mainly solves the technical problem that friction plate uses friction factor to reduce for a long time.The technical solution of the utility model is: a kind of moment of torsion tyre chain wheel apparatus, comprise axle sleeve, friction ring, hinge wheel, adjusting nut, hinge wheel, friction ring are socketed on the axle sleeve successively, hinge wheel and axle sleeve Spielpassung, friction ring is fixed by the adjusting nut that is screwed on the axle sleeve, it is characterized in that: a plurality of through holes that along the circumferential direction have even layout at the end face of hinge wheel, in through hole, settle spring, have semi-spherical grooves at corresponding axle sleeve with through hole and friction ring, be mounted with pellet shot from a slingshot in the groove, the elastic force of spring tightly is pressed against pellet shot from a slingshot on axle sleeve body and the friction ring.For preventing that adjusting nut from producing axial displacement, at adjusting nut a plurality of lock bolts are set circumferentially, the top of lock bolt is fixed in the keyway of axle sleeve.
The beneficial effects of the utility model are: the utility model mainly is to come transmitting torque by spring and pellet shot from a slingshot, the wearing and tearing of spring and pellet shot from a slingshot can be ignored, friction factor is constant, frictional force just can guarantee, the inefficacy of just can skidding of the hinge wheel of sprocket wheel anchor clamps, save the spare parts consumption of resin friction plate simultaneously, played the effect of cost efficiency.Gap between friction ring and the hinge wheel (promptly adjusting the elastic force of spring) is adjusted by adjusting nut, fixedly finishing of adjusting nut by lock bolt, so just can prevent that adjusting nut from producing axial displacement, the elastic force that has guaranteed spring is constant, and the reliability of moment of torsion transmission can guarantee fully.Eliminated the inefficacy of hinge wheel, promptly reduced workman's maintenance, service worker can guarantee the normal use of anchor clamps by the maintenance in cycle, guarantees normally delivery.

Among the figure: 1-axle sleeve, 2-pellet shot from a slingshot, 3-spring, 4-hinge wheel, 5-friction ring, 6-lock bolt, 7-adjusting nut, 8-keyway.
Embodiment: with reference to Fig. 1,2, a kind of moment of torsion tyre chain wheel apparatus comprises axle sleeve 1,2,8 springs 3 of 16 pellets shot from a slingshot, hinge wheel 4, friction ring 5,4 lock bolts 6, adjusting nut 7 has been processed 8 holes on the body of hinge wheel 4, be used for mounting spring 3, the hole of the semi-spherical grooves of axle sleeve 1 and friction ring 5 and hinge wheel 4 mounting spring is processing with one heart, and the both sides of spring 3 are installed a pellet shot from a slingshot 2 respectively, and pellet shot from a slingshot 2 is to locate by the semi-spherical grooves of axle sleeve and friction ring.Adjusting nut 7 is used for adjusting the gap between hinge wheel 4 and friction ring 5, the axle sleeve 1, and lock bolt 6 prevents that adjusting nut 7 from producing axial motions.By lock bolt 6 locking, prevent that adjusting nut 7 from rotating and produce axial displacement after the fixed-site of adjusting nut 7.Lock bolt 6 and adjusting nut 7 are to be threaded, with reference to Fig. 3,4, one end of lock bolt is fixed in the keyway of axle sleeve, axle sleeve 1 end has 6 keyways 8, lock bolt 6 just is fixed in the keyway at diagonal angle, 2 keyways of each use, the adjustment of regulating bolt all is the adjustment of 30 ° of multiples, adjusting nut 7 every half-twists, corresponding 90 ° of lockings will being fixed in the original keyway of bolt 6 of contracting, 60 ° of adjusting nut 7 every rotations, the locking fixing keyway of bolt 6 that contracts is constant, therefore can guarantee that lock bolt 6 can be fixed on the axle sleeve, play the effect that prevents the adjusting nut rotation.Whole drive system carry-over moment step by step in anchor clamps work, hinge wheel 4 is given transmission of torque in the process of worm screw, frictional force between axle sleeve 1 and the friction ring 5 is provided jointly by spring 3 and pellet shot from a slingshot 2, find that by continuous test the gap between friction ring 5 and the hinge wheel 4 is fixed on 0.15～0.20mm for best, spring can guarantee that under this kind elastic force the hinge wheel transmitting torque is reliable.The wearing and tearing of spring and pellet shot from a slingshot are negligible, and the elastic force of spring is a fixed value, so the moment of torsion that transmits is reliable.The axle sleeve 1 that has solved hinge wheel 4 and worm screw cooperation from root produces relative movement.The back of coming into operation of this structure find if fixed cycle safeguard spring and pellet shot from a slingshot, guaranteed the gap of friction ring and sprocket wheel, just can guarantee the normal operation of equipment.
