Description

Technical Field

[0001] The utility model relates to the technical field of speed reducers, in particular to a speed reducer convenient for maintenance. Background Technique

[0002] As is well known, a speed reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing, and is commonly used as a speed reduction transmission device between a prime mover and a working machine; in addition, the speed reducer plays a role in matching the speed and transmitting torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery.

[0003] When repairing the inside of the speed reducer, it is necessary to remove the cover on the top of the speed reducer housing, so as to facilitate the staff to operate on the inside of the speed reducer. However, the cover of the existing speed reducer needs to sequentially screw multiple groups of bolts during disassembly, and the disassembly process is time-consuming and laborious, which is not conducive to improving the working efficiency when repairing the speed reducer; for this reason, we propose a speed reducer convenient for maintenance. Content of the Utility Model

[0004] The purpose of the utility model is to provide a speed reducer convenient for maintenance to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a speed reducer convenient for maintenance, including: a speed reducer housing and a disassembly and assembly mechanism;

[0006] A cover is arranged on the top of the speed reducer housing. The disassembly and assembly mechanism includes slots symmetrically opened on the outer side of the speed reducer housing and a plate body fixedly connected to the top of the cover. A bidirectional lead screw is rotatably connected inside the plate body. Arc-shaped plates are threadedly connected to both opposite threads of the bidirectional lead screw. The bottom of the arc-shaped plate is fixedly connected with an insertion block through a connecting plate. The insertion block is used for inserting into the slot. A rod body is slidably connected inside the arc-shaped plate. One end of the rod body is fixedly connected to the plate body. A limit gear is fixedly sleeved on the bidirectional lead screw. A support is fixedly connected to the top of the plate body. A threaded rod is threadedly connected inside the support. The bottom end of the threaded rod is rotatably connected with an insertion plate for inserting into the tooth groove of the limit gear. One side of the insertion plate is movably connected to the plate body.

[0007] By adopting the above technical solution, when it is necessary to remove the box cover from the reducer housing, the plug plate can be driven away from the limit gear by loosening the threaded rod first, so that the bidirectional lead screw can rotate normally. Then, after the bidirectional lead screw rotates counterclockwise, it can drive the two arc-shaped plates to move away from each other on the rod body, so that the plug block can be moved out of the slot under the action of the connecting plate by the arc-shaped plate, and then the box cover can be removed from the reducer housing. In addition, when it is necessary to install the box cover on the reducer housing, the box cover can be first placed on the top of the reducer housing in a fitting manner, and then the two arc-shaped plates can be driven to approach each other by rotating the bidirectional lead screw clockwise, so that the plug block can be inserted into the slot, and by tightening the threaded rod, the plug plate can be driven to insert into the corresponding tooth groove on the limit gear, so that the bidirectional lead screw cannot rotate, and the box cover can be stably installed on the reducer housing.

[0008] Preferably, a base is fixedly connected to the bottom of the reducer housing, and through holes are uniformly formed in the interior of the base.

[0009] By adopting the above technical solution, it is convenient to fixedly install the reducer housing at a specified position.

[0010] Preferably, a stop block is fixedly connected to the end of the rod body far from the plate body.

[0011] By adopting the above technical solution, the movement of the arc-shaped plate can be limited, thereby preventing the arc-shaped plate from separating from the rod body.

[0012] Preferably, a driven bevel gear is fixedly sleeved on the bidirectional lead screw, a rotating shaft is rotatably connected to the interior of the bracket, a driving bevel gear is fixedly connected to the bottom end of the rotating shaft, and the outer side of the driving bevel gear is meshed with the driven bevel gear.

[0013] By adopting the above technical solution, the rotating shaft can drive the driven bevel gear to rotate through the driving bevel gear, so that the bidirectional lead screw can rotate clockwise or counterclockwise under the action of the rotating shaft.

[0014] Preferably, a handwheel is fixedly connected to the top end of the rotating shaft.

[0015] By adopting the above technical solution, it is convenient to rotate the rotating shaft.

[0016] Preferably, a handle is fixedly connected to the top of the handwheel.

[0017] By adopting the above technical solution, it is convenient to operate the handwheel.

[0018] Preferably, a convex block is welded to the top end of the threaded rod, and a groove is formed in the top of the convex block.

[0019] By adopting the above technical solution, it is convenient to insert a wrench into the bump to turn the threaded rod.

[0020] Preferably, a chute is formed on one side of the plate body, and the inner side wall of the chute is slidably connected with the insertion plate.

[0021] By adopting the above technical solution, the insertion plate can move up and down smoothly.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] In the reducer that is convenient for maintenance, by arranging a disassembly and assembly mechanism on the reducer box body and the box cover, after the threaded rod is loosened, the insertion plate can be driven to be withdrawn from the tooth groove of the limit gear, and after the bidirectional lead screw rotates counterclockwise, the two arc-shaped plates can be driven to move away from each other, so that the insertion block can be moved out of the slot, thereby facilitating the disassembly of the box cover and also facilitating the installation; through the above settings, the disassembly of the box cover is more time-saving and labor-saving, effectively improving the working efficiency of the staff when repairing the reducer.
