Description

Technical Field

[0001] The utility model belongs to the technical field of couplings, and in particular relates to a device for temporarily fixing internal and external teeth of a coupling. Background Art

[0002] The transport roller is a key equipment for plate production. Once the transport roller fails, it will directly affect the production and operation of the entire line. The transport roller and the output shaft of the reducer are usually connected through a gear coupling. The internal and external teeth of the gear coupling will wear due to long-term use or poor lubrication, and then the teeth will be broken. After the internal and external teeth of the coupling are broken, the roller operation will fail, affecting the normal production of the plate. It takes a long time to replace a new roller or the internal and external teeth of the coupling. In particular, the internal roller of the descaling machine and the quick cooling roller have many accessories to be replaced and removed, and the impact time caused by the failure will also be longer. Therefore, after the internal and external teeth of the plate transport roller coupling are broken, temporary disposal measures need to be taken to maintain normal production and operation. It is particularly important to minimize the impact time of the failure. Utility Model Content

[0003] The utility model aims to provide a device for temporarily fixing the inner and outer teeth of a coupling, so as to solve the problem that after the inner and outer teeth of the coupling are worn, it takes a long time to replace them, thus affecting the normal operation of production.

[0004] The technical solution of the utility model is: a device for temporarily fixing the inner and outer teeth of a coupling, the outer teeth of the coupling and the inner teeth of the coupling are coaxially arranged, including two semi-annular chucks, the two chucks are arranged between the outer teeth of the coupling and the inner teeth of the coupling, a plurality of holes are provided on the chucks, fixed connection blocks are inserted through the holes, the fixed connection blocks are adapted to the shapes of the holes, one side surface of the chuck is connected to the inner teeth of the coupling, one end of the fixed connection block extends out of the hole to be connected to the outer teeth of the coupling, and the other end of the fixed connection block extends out of the hole to fit the outer wall of the inner teeth of the coupling.

[0005] As a further improvement of the present invention, the holes are square holes, four of which are evenly and symmetrically arranged.

[0006] As a further improvement of the utility model, the chuck is coaxially arranged with the external teeth of the coupling and the internal teeth of the coupling.

[0007] The beneficial effects of the utility model are as follows: two chucks are symmetrically connected to the outer arc surface of the inner teeth of the coupling, the fixed connection block is inserted into the hole of the chuck, and then the fixed connection block is firmly welded to the outer arc surface of the outer teeth of the coupling, and the inner and outer teeth of the coupling are temporarily fixedly connected by the chuck and the fixed connection block, so as to maintain the normal operation of the roller, ensure the normal operation of production, and stop the machine to replace the roller coupling when the maintenance time allows. The utility model solves the problem that the tooth part of the plate transport roller gear coupling is worn due to long-term use, the tooth gap is increased or the lubrication is poor, causing the internal and external teeth to hit, the transport roller fails and cannot operate normally, and the maintenance time is too long to affect the normal operation of production.

[0008] The utility model can reliably connect the inner and outer teeth of the coupling after tooth punching, greatly shortening the impact time of failure and effectively ensuring the normal operation of production; the utility model can be installed in a short time without replacing the roller coupling, and is simple, convenient, fast, safe and efficient to use.

[0012] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0013] like Figure 1-Figure 2 As shown, a device for temporarily fixing the inner and outer teeth of a coupling, wherein the outer teeth 1 of the coupling and the inner teeth 3 of the coupling are coaxially arranged 5, and include two semi-annular chucks 2, the two chucks 2 are arranged between the outer teeth 1 of the coupling and the inner teeth 3 of the coupling, and the chucks 2 are provided with a plurality of holes 21, and a fixed connection block 4 is inserted through the holes 21, and the fixed connection block 4 is adapted to the shape of the holes 21, and the surface of one side of the chuck 2 is connected to the inner teeth 3 of the coupling, and one end of the fixed connection block 4 extends out of the hole 21 to connect with the outer teeth 1 of the coupling, and the other end of the fixed connection block 4 extends out of the hole 21 to fit the outer wall of the inner teeth 3 of the coupling. The semi-annular chuck 2 is easy to connect and set, and is easy to disassemble and assemble compared to the integrally formed disc, and can be installed without removing the outer teeth 1 of the coupling or the inner teeth 3 of the coupling, which saves time and effort, and is convenient and quick.

[0014] The hole 21 is a square hole, and there are four holes 21 that are evenly and symmetrically arranged. Compared with the round hole, the square hole 21 is easier to locate and has a higher anti-rotation ability. It can better adapt to the fixed connection block 4 and transmit the rotational torque, and can avoid the movement of the fixed connection block 4. It has better limitation and improves the connection effect. The evenly and symmetrical arrangement of the holes 21 can ensure the consistency of the force during operation and improve the stability of the working operation.

[0015] The chuck 2 is coaxially arranged with the outer teeth 1 and the inner teeth 3 of the coupling; the coaxial arrangement 5 can effectively improve the effect of the rotation of the inner and outer teeth of the coupling, and further improve the reliability of the chuck 2 temporarily fixing the outer teeth 1 and the inner teeth 3 of the coupling to ensure the working operation.

[0016] When the inner and outer teeth of the coupling of the plate transport roller of the steel rolling production line are chipped, the equipment is first shut down, and the one side surface of the two pre-prepared chucks 2 is welded to the outer arc surface of the inner teeth 3 of the coupling by electric welding. The two chucks 2 form a split chuck 2 structure, which is convenient for installation and connection; four fixed connection blocks 4 are inserted into the four square holes 21 of the chuck 2. The size of the square hole 21 is slightly larger than the size of the fixed connection block 4, leaving a certain margin to prevent the insertion from being too tight and causing malfunctions during operation; one end of the fixed connection block 4 extending out of the hole 21 close to the inner teeth 3 of the coupling is in contact with the outer wall of the inner teeth 3 of the coupling, which can further fix the inner teeth 3 of the coupling and improve the reliability of the connection; the other end of the fixed connection block 4 extending out of the hole 21 is firmly welded to the outer arc surface of the outer teeth 1 of the coupling.

[0017] The inner teeth 3 of the coupling are temporarily fixedly connected to the outer teeth 1 of the coupling by means of the split chuck 2 and the fixed connecting block 4, and a certain amount of play is retained to effectively maintain the normal operation of the roller table. When the production task is completed and the maintenance time permits, the chuck 2 is removed and the roller table coupling is replaced.
