Abstract
The utility model discloses a tyre coupling for the hoisting of a dummy bar. The tyre coupling comprises two half couplings on the left side and on right side, two clamp rings on the left side and the right side, tyre rings and hold-down bolts; at least two circular arc-shaped rigid catchers are respectively arranged on the opposite end faces of the two half couplings on the left and the right sides; the inner and the outer circular arc edges of the circular arc-shaped rigid catchers are concentric with the circular ring-shaped end faces of the two half couplings on the left and the right sides; and the circular arc-shaped rigid catcher on the half coupling on the left side and the circular arc-shaped rigid catcher on the half coupling on the right side are staggered. Under the status that the tyre rings of the tyre coupling are not loosed, the coupling works normally, and the circular arc-shaped rigid catchers are not contacted and collided; and only when the tyre rings are separated from the coupling, the circular arc-shaped rigid catchers on the two sides are contacted with each other for playing the role of a temporary coupling. The tyre coupling can reduce the occurrence of the falling accident of the dummy bar, so that the normal running of equipment and the smooth production are ensured.
Description
Technical field
The utility model relates to a kind of coupling, refers to a kind of dummy bar elevator coupling with rubber type element particularly.
Background technique
Coupling is the transmission device of driving device driven by motor various device running.Coupling with rubber type element is used to connect motor and break in the dummy bar hoist driving device, and break connects speed reducer again.Existing coupling with rubber type element mainly is made up of half-coupling, hold-down ring, tyre ring and the hold-down bolt of fixed electrical machinery axle and fixed equipment axle, hold-down ring is fixed on the half-coupling by hold-down bolt, and by hold-down bolt tyre ring is pressed and to be stuck between half-coupling and the hold-down ring, the end face of two half-couplings has certain clearance.Motor one side half-coupling rotates, and half-coupling rotates together by the connection drive opposite side half-coupling of tyre ring.
The transmission principle of dummy bar winding plant is: during motor action, break is opened, and motor drives the speed reducer input shaft by coupling with rubber type element and rotates, and speed reducer output shaft links to each other with reel, and drive reel and rotate, thus the elevating movement of control elevator hook.
Because the dummy bar device that the elevator hook hangs has tens tons of weights, if transmission device breaks down, causes dummy bar to be slipped on the roller-way, will hinder the operation of strand on roller-way of production, causes production interruption accident.So the situation that is connected to coupling in the dummy bar winding plant driving mechanism and brakeage precision and component requires very high.In the production process at the scene, occur sometimes causing serious potential faults to production because coupling with rubber type element connects the phenomenon that the dummy bar of loosening former thereby generation glides.Analyze reason and mainly be by the structures shape of coupling with rubber type element, the loosening or fracture of the hold-down bolt above coupling with rubber type element, thus cause the tyre ring on the coupling to get loose from coupling, the half-coupling of coupling both sides will lose connection.And lifting dummy bar when action, break is opened, though motor is rotating, but transmission disconnects from the coupling with rubber type element that damages, motor and speed reducer loses and is in transmission connection, speed reducer and reel are subjected to the action of gravity of dummy bar and rotational action, thereby cause dummy bar tenesmus accident, the carrying out that serious threat is produced.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of dummy bar elevator coupling with rubber type element, and it can not only connect motor and break, and can meet an urgent need when coupling gets loose at tyre ring and to connect the transmission shaft of both sides.
For solving the problems of the technologies described above, the dummy bar elevator coupling with rubber type element that the utility model is designed, comprise left and right sides half-coupling, left and right sides hold-down ring, tyre ring and hold-down bolt, on the half-coupling opposing end faces of the left and right sides, be provided with at least two circular arc rigidity catchers separately, the inside and outside circular arc limit of described circular arc rigidity catcher and the concyclic heart of ring end face of left and right sides half-coupling, and catcher of the circular arc rigidity on the half-coupling of left side and the staggered layout that cooperates of the circular arc rigidity catcher on the half-coupling of right side.
Preferably, the interior circular arc limit of described circular arc rigidity catcher overlaps with the end face inner edge of left and right sides half-coupling, and the external arc limit of described circular arc rigidity catcher overlaps with the end face outer rim of left and right sides half-coupling.The inside and outside circular arc of circular arc rigidity catcher all overlaps with the interior outer rim of half-coupling end face, and the stress surface between the circular arc rigidity catcher of the increase left and right sides connects more firm.
Preferably, be provided with the circular arc rigidity catcher of two symmetric arrangement on the half-coupling opposing end faces of the described left and right sides separately.Arc round angle α=70～80 of circular arc rigidity catcher °, preferred α=75 °.Can avoid impact and collision on the circular arc rigidity catcher circumferencial direction in normal operation; Only get loose from coupling at tyre ring, the circular arc rigidity catcher of both sides just can touch together, plays the effect of interim coupling.
Advantage of the present utility model is: adopt said structure, when tyre ring when coupling gets loose or come off, the circular arc rigidity of both sides is taken over the emergent transmission that fits together that will interlock, play the effect of interim coupling, reduce because the generation of coupling with rubber type element former thereby the dummy bar tenesmus accident that causes, thereby guaranteed the normal operation of equipment and carrying out smoothly of production.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The elevator of dummy bar shown in figure coupling with rubber type element, the half-coupling 1 that comprises the left and right sides, 6, the hold-down ring 3 of the left and right sides, 5, tyre ring 4 and hold-down bolt 2, at left and right sides half-coupling 1, be provided with the circular arc rigidity catcher 7 of two symmetric arrangement on 6 opposing end faces separately, the external arc limit and the left and right sides half-coupling 1 of circular arc rigidity catcher 7,6 the concyclic heart of ring end face, the interior circular arc limit and the left and right sides half-coupling 1 of circular arc rigidity catcher 7,6 end face inner edge overlaps, and the circular arc rigidity catcher 7 on the left side half-coupling 1 is taken over the 7 staggered layouts that cooperate with the circular arc rigidity on the right side half-coupling 6.Arc round angle α=75 of described circular arc rigidity catcher 7 °.
During installation: the half- coupling 1,6 of the left and right sides is separately fixed on motor shaft and the equipment axis, and two circular arc rigidity catchers 7 on the left side half-coupling 1 took over for 7 staggered cooperations with two circular arc rigidity on the right side half-coupling 6; Left side hold-down ring 3 is fixed on the half-coupling 1 of left side by hold-down bolt 2, and right side hold-down ring 5 is fixed on the right side half-coupling 6 by hold-down bolt 2, and by hold-down bolt 2 tyre ring 4 pressures is stuck between half-coupling and the hold-down ring.
Under the situation that the tyre ring 4 of coupling with rubber type element does not get loose, coupling runs well, and the circular arc rigidity catcher 7 of both sides can contact-impact.Only after tyre ring 4 got loose from coupling, the circular arc rigidity of both sides catcher 7 just can touch together, plays the effect of interim coupling.
