Description

Technical Field

[0001] This utility model relates to the field of gear locking technology, and more specifically, to a driven gear anti-deviation locking device. Background Technology

[0002] Driven gears are core components in mechanical transmission systems. They are gears that passively receive power and transmit torque in a gear pair, meshing with the driving gear to achieve changes in speed, torque, or direction of motion. When driven gears rotate, the lack of an anti-deviation locking structure can cause axial movement, which disrupts normal gear meshing, leading to uneven tooth wear, increased transmission noise, and even the risk of tooth breakage. Utility Model Content

[0003] The main purpose of this utility model is to provide a driven gear anti-deviation locking device, which can effectively solve the problem in the background art that when the driven gear rotates, the lack of an anti-deviation locking structure will cause the driven gear to move axially, which will destroy the normal meshing of the gear, causing uneven wear of the tooth surface, increased transmission noise, and even the risk of tooth loss.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A driven gear anti-deviation locking device includes a base, with telescopic rods provided on both sides of the upper surface of the base, and a lifting seat fixedly installed on the upper ends of the two telescopic rods. A limiting component for limiting the position is provided on the upper surface of the lifting seat.

[0006] The upper surface of the base is provided with a drive component for driving the lifting seat to move up and down.

[0007] Preferably, the limiting component includes a sliding frame, which is fixedly installed on the upper surface of the lifting seat. Two sliders are slidably arranged inside the sliding frame. A movable plate is fixedly installed on the upper surface of each of the two sliders. Several mounting columns are fixedly installed on the opposite side of each of the two movable plates.

[0008] A bidirectional lead screw is rotatably installed between the two sides of the inner wall of the sliding frame. The two sliders are respectively threaded on both sides of the bidirectional lead screw. A first motor is fixedly installed on one side of the sliding frame. One end of the bidirectional lead screw passes through the sliding frame and is fixedly connected to the output shaft end of the first motor.

[0009] Preferably, each of the mounting posts has a ball bearing rotatably mounted on one end surface.

[0010] Preferably, the drive assembly includes a mounting slot, which is formed on the upper surface of the base. A rotating rod is rotatably mounted between the two sides of the inner wall of the mounting slot. An eccentric wheel is sleeved on the rod body. A second motor is fixedly mounted on one side of the base. One end of the rotating rod passes through the base and is fixedly connected to the output shaft end of the second motor.

[0011] Preferably, both sides of the upper surface of the base are provided with clamping components for clamping.

[0012] Preferably, the clamping assembly includes a cylinder, which is fixedly installed on the corresponding side of the upper surface of the base, and an arc-shaped clamp is fixedly installed at the output end of the cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The staff activates the drive assembly to drive the lifting seat to rise and fall, thereby moving the mounting column to the position of the driven gear. Then the staff starts the first motor, which drives the double-headed screw to rotate. The rotating double-headed screw drives the two sliders to move through the screw thread, so that the ball at one end of the mounting column can press against the driven gear. Under the rotation of the ball, the driven gear is prevented from being worn too much when it rotates. Under the pressing action of the ball, the driven gear is prevented from moving axially.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1-4 As shown, a driven gear anti-deviation locking device includes a base 1, with telescopic rods 2 on both sides of the upper surface of the base 1, and a lifting seat 3 fixedly installed on the upper ends of the two telescopic rods 2. A limiting component 4 for limiting is provided on the upper surface of the lifting seat 3.

[0022] The upper surface of the base 1 is provided with a drive component 5 for driving the lifting seat 3 to rise and fall.

[0023] The limiting component 4 includes a sliding frame 401, which is fixedly installed on the upper surface of the lifting seat 3. Two sliders 402 are slidably arranged inside the sliding frame 401. A movable plate 403 is fixedly installed on the upper surface of each slider 402. Several mounting posts 404 are fixedly installed on the opposite side of each movable plate 403.

[0024] A bidirectional lead screw 405 is rotatably installed between the two sides of the inner wall of the sliding frame 401. Two sliders 402 are respectively threaded on both sides of the body of the bidirectional lead screw 405. A first motor 406 is fixedly installed on one side of the sliding frame 401. One end of the bidirectional lead screw 405 passes through the sliding frame 401 and is fixedly connected to the output shaft end of the first motor 406.

[0025] Each mounting post 404 has a ball bearing 407 rotatably mounted on one end surface.

[0026] The operator activates the drive assembly 5, which drives the lifting seat 3 to rise and fall, thereby moving the mounting column 404 to the position of the driven gear. Then, the operator starts the first motor 406, which drives the double-headed screw 405 to rotate through its output shaft. The rotating double-headed screw 405 drives the two sliders 402 to move through the threaded screw, so that the ball bearing 407 at one end of the mounting column 404 can tighten against the driven gear. Under the rotation of the ball bearing 407, excessive wear is prevented from occurring on the driven gear during rotation, and axial movement of the driven gear is prevented under the tightening action of the ball bearing 407.

[0027] In another embodiment of the present invention, the drive assembly 5 includes a mounting groove 501, which is formed on the upper surface of the base 1. A rotating rod 502 is rotatably mounted between the two sides of the inner wall of the mounting groove 501. An eccentric wheel 503 is sleeved on the rod body of the rotating rod 502. A second motor 504 is fixedly mounted on one side of the base 1. One end of the rotating rod 502 passes through the base 1 and is fixedly connected to the output shaft end of the second motor 504.

[0028] The staff starts the second motor 504, which drives the rotating rod 502 to rotate. The rotating rod 502 drives the eccentric wheel 503 to rotate. The rotating eccentric wheel 503 pushes the lifting seat 3, so that the lifting seat 3 can move in the direction of the telescopic rod 2.

[0029] In another embodiment of this utility model, clamping components 6 for clamping are provided on both sides of the upper surface of the base 1.

[0030] The clamping assembly 6 includes a cylinder 601, which is fixedly installed on the corresponding side of the upper surface of the base 1, and an arc-shaped clamping plate 602 is fixedly installed at the output end of the cylinder 601.

[0031] The staff started the cylinder 601, which caused its output end to drive the arc-shaped clamp 602 to press against the moving end of the telescopic rod 2, so that the lifting seat 3 could stably support the mounting column 404.

[0032] The working principle of this driven gear anti-deviation locking device is as follows:

[0033] In use, the operator activates the drive assembly 5 to drive the lifting seat 3 to rise and fall, thereby moving the mounting column 404 to the position of the driven gear. Then, the operator starts the first motor 406, causing its output shaft to drive the double-acting screw 405 to rotate. The rotating double-acting screw 405 drives the two sliders 402 to move through the threaded advance, so that the ball bearing 407 at one end of the mounting column 404 can tighten against the driven gear. Under the rotation of the ball bearing 407, excessive wear on the driven gear during rotation is prevented, and under the tightening action of the ball bearing 407, axial movement of the driven gear is prevented.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
