Description

Technical Field

[0001] The utility model relates to the field of gearbox assemblies, and particularly to a gearbox assembly. Background Art

[0002] Gearbox assemblies have the advantages of wide application range, high benefits, good effects, and low operating costs. There are many types of gearbox assemblies, among which the transmission achieved through the meshing of gears and racks is widely used. However, in existing gearbox assemblies, usually a single gear is used to drive a single rack to move, resulting in unstable movement of the rack, thus affecting the stable progress of the transmission.

[0003] To solve the above problems, a gearbox assembly is thus proposed here. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a gearbox assembly to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A gearbox assembly includes a bearing seat. At the top and bottom inside the bearing seat, two ball bearings are provided. Between the two ball bearings on the same side, a shaft rod is rotatably arranged. On both sides of the top of the bearing seat, two first mounting blocks are fixedly provided. On the top of the two first mounting blocks, a machine base is fixedly connected. On the top of the two machine bases, a second mounting block is fixedly connected. On the top between the two second mounting blocks, a transmission box is fixedly provided. The top ends of the two shaft rods respectively pass through the two machine bases and extend into the interior of the transmission box to be fixedly connected with driven wheels. On one side of the bottom end of the transmission box, a motor is fixedly installed. The output end of the motor extends into the interior of the transmission box to be fixedly connected with a driving wheel. A belt is arranged for transmission between the driving wheel and the two driven wheels. At the bottom ends of the two shaft rods, threaded rods are fixedly connected. At the bottom ends of the two threaded rods, gears are provided. On one side between the two gears, a rack is meshed. At the bottom end of the rack, a moving plate is provided.

[0006] The driving wheel is driven to rotate by the motor. Since a belt is arranged for transmission between the driving wheel and the two driven wheels, the two driven wheels are driven to rotate, thereby driving the two shaft rods to rotate, and then driving the two gears to rotate. Since the two gears are both meshed with the rack, the rack is driven to move left and right, thus facilitating the long-distance left and right movement of the moving plate. Since a single rack is driven by two gears, the stable left and right movement of the rack and the moving plate can be ensured.

[0007] Preferably, an installation groove is formed at the connection between the moving plate and the rack. The installation groove is engaged with the rack, and a plurality of second fixing holes are formed at the connection between the installation groove and the rack. The arrangement of the plurality of second fixing holes facilitates fixing the rack on the moving plate.

[0008] Preferably, four fifth fixing holes are formed at the connection between the motor and the transmission box, and four fourth fixing holes are formed at the connection between the transmission box and the motor. The cooperative arrangement of the four fifth fixing holes and the four fourth fixing holes facilitates fixedly installing the motor on the transmission box.

[0009] Preferably, four first mounting holes are formed at the connection between the two first mounting blocks and the bearing seat, and four second mounting holes are formed at the connection between the two second mounting blocks and the transmission box. The arrangement of the first mounting holes and the four second mounting holes facilitates the fixed connection between the two first mounting blocks and the bearing seat and between the two second mounting blocks and the transmission box.

[0010] Preferably, rotating shafts are fixedly arranged on both sides of the bottom end of the inner wall of the transmission box. Transmission wheels are rotatably arranged on the surfaces of the two rotating shafts, and the two transmission wheels are correspondingly arranged with the belt. The arrangement of the two transmission wheels facilitates the stable operation of the belt.

[0011] Preferably, a through hole is formed in the front of the bearing seat, and fixing strips are fixedly arranged on both sides of the bearing seat. A plurality of first fixing holes are formed on the surfaces of the two fixing strips. The arrangement of the two fixing strips and the plurality of first fixing holes facilitates the fixed installation of this component.

[0012] Preferably, bearing caps are fixedly arranged at the connections between the four ball bearings and the bearing seat. The arrangement of the bearing caps facilitates the stable operation of the ball bearings.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The motor drives the driving wheel to rotate. Since a belt is arranged for transmission between the driving wheel and the two driven wheels, the two driven wheels are driven to rotate, thereby driving the two shaft rods to rotate, and then driving the two gears to rotate. Since the two gears are both engaged with the rack, the rack is driven to move left and right, thereby facilitating driving the moving plate to move left and right over a long distance. Since a single rack is driven by two gears, the stable left and right movement of the rack and the moving plate can be ensured, and then the stable progress of the transmission can be ensured.
