Description

Technical Field

[0001] The utility model relates to the technical field of speed reducers, in particular to a speed reducer with a fixed structure at the bottom. Background Technique

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

[0003] When the traditional speed reducer with a fixed structure at the bottom is used in combination with motors of different models, the mounting frame cannot be adjusted. When the size of the motor is small, the motor needs to be raised for installation, and at this time, the motor is not easy to fix and is prone to looseness, which affects the use. Content of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable speed reducer with a fixed structure at the bottom.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] A speed reducer with a fixed structure at the bottom includes a fixed base, and is characterized in that: a speed reducer is bolted on one side of the upper surface of the fixed base, an installation frame is installed on the other side of the upper surface of the fixed base, a connecting rod is rotatably connected inside the installation frame, a bevel gear A is installed on one side of the outer surface of the connecting rod, the bevel gear A is meshed with a bevel gear B, a screw rod A is installed on the lower surface of the bevel gear B, the lower end of the screw rod A is rotatably connected with the upper surface of the fixed base, the screw rod A is threadedly connected with an installation plate, the side surface of the installation plate is closely attached to the surface of the installation frame, a plurality of installation holes are formed on the surface of the installation plate, the end of the connecting rod penetrates through the installation frame and extends outwards, and a crank is connected to the end of the connecting rod, and shock absorbers are arranged at the four ends of the lower surface of the fixed base.

[0007] It can be seen that when the device is in use, the speed reducer is first installed on the fixed base. The operator rotates the crank handle. Since the crank handle is fixedly connected to the connecting rod, and a bevel gear A is installed on the surface of the connecting rod, the rotation of the crank handle can drive the connecting rod and the bevel gear A to rotate. Since the bevel gear A is meshed with the bevel gear B, the bevel gear B is connected to the screw A, and the screw A is rotationally connected to the fixed base, the rotation of the bevel gear A drives the bevel gear B and the screw A to rotate. Also, since the surface of the screw A is threadedly connected to the mounting plate, and the mounting plate is in close fit with the mounting frame, the mounting plate is limited by the mounting frame. When the screw A rotates, the mounting plate moves up and down along the surface of the screw A. Therefore, rotating the crank handle can adjust the position of the mounting plate. Since the mounting plate is provided with a plurality of mounting holes, the motor can be fixed by using the mounting holes. The adjustable mounting plate is suitable for motors of different heights and can fix the motor, increasing the flexibility during use, avoiding the influence on motors of different models, and improving the versatility.

[0008] Furthermore, fixing plates are provided on both sides of the speed reducer. The fixing plates are fixedly connected to the upper surface of the fixed base. A screw B is threadedly connected to the surface of the fixing plate. The screw B penetrates through the fixing plate, and a fixing disc is installed at the end of the screw B. The fixing disc is in close fit with the surface of the speed reducer.

[0009] Since both fixing plates are fixedly connected to the fixed base and are threadedly connected with the screw B, and the screw B penetrates through the fixing plate, rotating the screw B can make the screw B move along the penetrating direction. Since a fixing disc is installed at the end of the screw B, and the fixing disc can be in close fit with the surface of the speed reducer, the speed reducer can be fixed by the fixing discs on both sides, increasing the fixing stability and improving the fixing effect.

[0010] Furthermore, a fixing hole A is provided on the outer surface of one side of the crank handle, and a plurality of fixing holes B are provided on the outer surface of one side of the mounting frame. The plurality of fixing holes B are evenly distributed in a ring shape. The crank handle is provided with a fixing plug, and both ends of the fixing plug are respectively inserted into the fixing hole A and the fixing hole B.

[0011] Since the crank handle and the mounting frame are respectively provided with the fixing hole A and the fixing hole B, and the fixing plug can be inserted into the fixing hole A and the fixing hole B at the same time, the crank handle can be fixed by the fixing plug to prevent the crank handle from rotating self, achieving the purpose of fixing the position of the mounting plate, preventing loosening from affecting the connection between the speed reducer and the motor, and improving the stability of the device.

[0012] Furthermore, a damping telescopic rod B is inserted into the upper end of the shock absorber. The upper end of the damping telescopic rod B is fixedly connected to the lower surface of the fixed base. The lower surface of the shock absorber is connected to a bottom plate. The lower end of the damping telescopic rod B is fixedly connected to the upper surface of the bottom plate. A buffer plate is installed on the outer surface of the damping telescopic rod B. A plurality of buffer holes are provided on the surface of the buffer plate. A buffer liquid is filled in the shock absorber.

[0013] Since the damping telescopic rod B inserted in the shock absorber is connected to the fixed base, the damping telescopic rod B can expand and contract within the shock absorber. Also, since the damping telescopic rod B is equipped with a buffer plate which has multiple buffer holes, and the inside of the shock absorber is filled with buffer liquid, when the reducer operates and generates vibrations, the expansion and contraction of the damping telescopic rod B drives the buffer plate to move. Affected by the buffering of the buffer holes and the buffer liquid to reduce vibrations, it avoids damage to the reducer components caused by vibrations and extends the service life of the equipment.

[0014] Further, there are two sets of bevel gears A. The screws A connected to the two sets of bevel gears A are both threadedly connected to the same mounting plate. The upper surface of the fixed base is equipped with a damping telescopic rod A, and the upper end of the damping telescopic rod A is fixedly connected to the lower surface of the mounting plate.

[0015] Since there are two sets of bevel gears A and the two screws A are both threadedly connected to the same mounting plate, when the connecting rod rotates, it drives the two screws A to rotate. The mounting plate moves up and down under the drive of the two screws A, and a damping telescopic rod A is connected between the mounting plate and the fixed base. Therefore, the stability during the adjustment of the mounting plate can be increased, making the installation of the motor not prone to looseness and more stable.

[0016] Further, a spring is sleeved on the surface of the damping telescopic rod B, and the two ends of the spring are respectively abutted against the lower surface of the buffer plate and the upper surface of the bottom plate.

[0017] Since the two ends of the spring are abutted against the bottom plate and the buffer plate, when the damping telescopic rod B contracts under vibration, it can be restored under the elastic force of the spring, enhancing the damping effect. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0024] The present utility model will be described in detail below with reference to the accompanying drawings.

[0025] As Figures 1-5 shown, a speed reducer with a fixed structure at the bottom includes a fixed base 10, and is characterized in that: a speed reducer 11 is bolted on one side of the upper surface of the fixed base 10, and a mounting frame 20 is installed on the other side of the upper surface of the fixed base 10. A connecting rod 21 is rotatably connected inside the mounting frame 20. A bevel gear A 22 is installed on one side of the outer surface of the connecting rod 21. The bevel gear A 22 is meshed with a bevel gear B 23. A screw A 24 is installed on the lower surface of the bevel gear B 23. The lower end of the screw A 24 is rotatably connected with the upper surface of the fixed base 10. The screw A 24 is threadedly connected with a mounting plate 25. The side surface of the mounting plate 25 is in close fit with the surface of the mounting frame 20. A plurality of mounting holes 26 are formed on the surface of the mounting plate 25. The end of the connecting rod 21 penetrates through the mounting frame 20 and extends outwards, and a crank 40 is connected to the end of the connecting rod 21. Shock absorbers 50 are arranged at the four ends of the lower surface of the fixed base 10.

[0026] When the device is in use, first install the speed reducer 11 on the fixed base 10. The operator rotates the crank 40. Since the crank 40 is fixedly connected to the connecting rod 21, and the bevel gear A 22 is installed on the surface of the connecting rod 21, the rotation of the crank 40 can drive the connecting rod 21 and the bevel gear A 22 to rotate. Since the bevel gear A 22 is meshed with the bevel gear B 23, the bevel gear B 23 is connected to the screw A 24, and the screw A 24 is rotatably connected to the fixed base 10, the rotation of the bevel gear A 22 drives the bevel gear B 23 and the screw A 24 to rotate. Also, since the surface of the screw A 24 is threadedly connected to the mounting plate 25, and the mounting plate 25 is in close fit with the mounting frame 20, the mounting plate 25 is limited by the mounting frame 20. When the screw A 24 rotates, the mounting plate 25 moves up and down along the surface of the screw A 24. Therefore, rotating the crank 40 can adjust the position of the mounting plate 25. Since a plurality of mounting holes 26 are formed on the mounting plate 25, the motor can be fixed by using the mounting holes 26. The adjustable mounting plate 25 is suitable for motors of different heights, and can fix the motor, increasing the flexibility during use, avoiding the influence of different models of motors, and improving the versatility.

[0027] Specifically, fixing plates 30 are provided on both sides of the speed reducer 11. The fixing plates 30 are fixedly connected to the upper surface of the fixed base 10. A screw B31 is threadedly connected to the surface of the fixing plate 30. The screw B31 penetrates through the fixing plate 30. A fixed disk 32 is installed at the end of the screw B31. The fixed disk 32 is in close contact with the surface of the speed reducer 11. Since both fixing plates 30 are fixedly connected to the fixed base 10 and are threadedly connected with screw B31, and the screw B31 penetrates through the fixing plate 30, rotating the screw B31 can make the screw B31 move along the penetration direction. Since a fixed disk 32 is installed at the end of the screw B31 and the fixed disk 32 can be in close contact with the surface of the speed reducer 11, the speed reducer 11 can be fixed by the fixed disks 32 on both sides, increasing the fixing stability and improving the fixing effect.

[0028] Specifically, a fixing hole A41 is provided on the outer surface of one side of the crank 40. A plurality of fixing holes B42 are provided on the outer surface of one side of the mounting frame 20. The plurality of fixing holes B42 are evenly distributed in a ring shape. The crank 40 is provided with a fixing plug 43. The two ends of the fixing plug 43 are respectively inserted into the fixing hole A41 and the fixing hole B42. Since the crank 40 and the mounting frame 20 are respectively provided with the fixing hole A41 and the fixing hole B42, and the fixing plug 43 can be inserted into the fixing hole A41 and the fixing hole B42 at the same time, the crank 40 can be fixed by the fixing plug 43 to prevent the crank 40 from rotating self, achieving the purpose of fixing the position of the mounting plate 25 and preventing loosening from affecting the connection between the speed reducer 11 and the motor, improving the stability of the device.

[0029] Specifically, a damping telescopic rod B51 is inserted into the upper end of the shock absorber 50. The upper end of the damping telescopic rod B51 is fixedly connected to the lower surface of the fixed base 10. The lower surface of the shock absorber 50 is connected to a bottom plate 52. The lower end of the damping telescopic rod B51 is fixedly connected to the upper surface of the bottom plate 52. A buffer plate 53 is installed on the outer surface of the damping telescopic rod B51. A plurality of buffer holes 54 are provided on the surface of the buffer plate 53. The inside of the shock absorber 50 is filled with buffer liquid. Since the damping telescopic rod B51 inserted into the shock absorber 50 is connected to the fixed base 10, the damping telescopic rod B51 can expand and contract in the shock absorber 50. Also, since a buffer plate 53 is installed on the damping telescopic rod B51, a plurality of buffer holes 54 are provided on the buffer plate 53, and the inside of the shock absorber 50 is filled with buffer liquid. Therefore, when the speed reducer 11 operates and generates vibrations, the expansion and contraction of the damping telescopic rod B51 drives the buffer plate 53 to move. Affected by the buffering of the buffer holes 54 and the buffer liquid to reduce vibrations, it avoids damage to the components of the speed reducer 11 caused by vibrations and extends the service life of the equipment.

[0030] Specifically, there are two sets of bevel gears A22. The screws A24 connected to the two sets of bevel gears A22 are both threadedly connected to the same mounting plate 25. A damping telescopic rod A27 is mounted on the upper surface of the fixed base 10, and the upper end of the damping telescopic rod A27 is fixedly connected to the lower surface of the mounting plate 25. Since there are two sets of bevel gears A22 and the two screws A24 are both threadedly connected to the same mounting plate 25, when the connecting rod 21 rotates, the two screws A24 are driven to rotate. The mounting plate 25 moves up and down under the drive of the two screws A24, and a damping telescopic rod A27 is connected between the mounting plate 25 and the fixed base 10. Therefore, the stability of the mounting plate 25 during adjustment can be increased, making the installation of the motor not prone to looseness and more stable.

[0031] Specifically, a spring 55 is sleeved on the surface of the damping telescopic rod B51. The two ends of the spring 55 are respectively abutted against the lower surface of the buffer plate 53 and the upper surface of the bottom plate 52. Since the two ends of the spring 55 are abutted against the bottom plate 52 and the buffer plate 53, when the damping telescopic rod B51 contracts under vibration, it can be restored under the elastic force of the spring 55, enhancing the damping effect.

It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several equivalent substitutions or obvious modifications are made, and the performance or use is the same, and all should be regarded as belonging to the patent protection scope determined by the claims submitted by the present invention.
