Description

A speed reducer mounting structure Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to an installation structure for a speed reducer. Background Technology

[0002] A speed reducer is a precision mechanical device primarily used to convert high-speed, low-torque input shafts into low-speed, high-torque output shafts. The working principle of a speed reducer is that a small gear on the input shaft drives a large gear on the output shaft, achieving speed reduction and torque transmission. Specifically, the input shaft gear has fewer teeth, while the output shaft gear has more teeth; therefore, the output shaft speed decreases, but the torque increases accordingly. During the installation of a speed reducer, it is crucial to ensure that the motor shaft and the gearbox input shaft do not tilt. This can be achieved by slowly inserting the motor shaft into the gearbox input shaft.

[0003] In the existing technology, the traditional installation process of connecting motors and gearboxes has the following shortcomings: First, the coaxiality needs to be adjusted manually and repeatedly during installation, which is cumbersome and the accuracy is difficult to guarantee; second, there is a lack of effective guiding and positioning mechanisms, which poses safety hazards when installing heavy equipment; and third, the rigid connection method makes later maintenance and adjustment difficult. Therefore, we propose an installation structure for the gearbox to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a speed reducer installation structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A speed reducer mounting structure includes a base plate, a machine base fixedly connected to the top of the base plate, a motor fixedly connected to the top of the machine base, an input sleeve sleeved on the outer wall of the motor output shaft, a speed reducer installed at one end of the input sleeve, an ear plate fixedly connected to the outer wall of the speed reducer, and mating sleeves fixedly connected to both the ear plate and the outer wall of the speed reducer, with mating rods threaded to the inner walls of both mating sleeves, and a mating assembly provided on the outer wall of the machine base.

[0007] Preferably, the docking assembly includes two docking plates, the bottom of which is fixedly connected to the top of the base. The outer walls of the two docking plates are provided with docking holes, the inner walls of which are slidably connected to the outer walls of the two docking rods. The outer walls of the two docking rods are threaded with two locking caps. The docking assembly facilitates the docking and installation of the motor and the gearbox.

[0008] Preferably, the outer wall of the base plate has multiple mounting holes, and the motor is horizontally supported by the base plate and the mounting holes.

[0009] Preferably, the outer wall of the gearbox is rotatably fitted with an output sleeve, and the gear inside the gearbox is connected to the output sleeve for rotation.

[0010] Preferably, guide caps are slidably fitted on the outer walls of both docking rods, and the bottoms of both guide caps are fixedly connected to the top of the base plate. The horizontal docking capability of the docking rods is increased by setting guide caps.

[0011] Preferably, one end of the locking cap is pressed against the outer wall of the docking plate, and the docking rod is fixed to the docking plate by setting the locking cap.

[0012] Preferably, both the base and the gearbox have multiple mounting holes at their bottoms.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] This solution achieves rapid and accurate positioning by setting up ear plates, docking sleeves, docking rods, guide caps, docking plates, and locking caps, ensuring coaxiality during installation. The adjustable locking cap structure allows the reducer to smoothly and horizontally dock with the motor and securely fix it. The entire installation process is simple to operate, requiring no repeated adjustments, which improves installation efficiency, ensures horizontal docking, and facilitates later maintenance and adjustment.

The diameter of the mounting holes 2 is designed according to actual installation requirements to facilitate fixed connection with the equipment foundation via bolts. The base plate 1 is made of high-strength steel plate and serves as the basic support component of the entire mounting structure. A base 3 is fixedly connected to the top of the base plate 1, and a motor 4 is fixedly connected to the top of the base 3. An input sleeve 5 is fitted onto the outer wall of the output shaft of the motor 4. A key block is provided on the outer wall of the motor 4, while a keyway is provided inside the input sleeve 5. The two work together to achieve transmission. A speed reducer 6 is mounted on one end of the input sleeve 5, and the input sleeve 5 acts as a half-coupling connected to the input end of the speed reducer 6. An output sleeve 7 is rotatably embedded in the outer wall of the speed reducer 6.

[0023] The outer wall of the gearbox 6 is fixedly connected with a lug plate 8. Both the lug plate 8 and the outer wall of the gearbox 6 are fixedly connected with a mating sleeve 9.

Multiple assembly holes 14 are opened at the bottom of the base 3 and the gearbox 6.

[0026] Working principle: When the motor 4 and the gearbox 6 are connected and installed, the base plate 1 is first fixedly installed through multiple mounting holes 2. Then, one end of each of the two connecting rods 10 is screwed into the two connecting sleeves 9 to fix the two connecting rods 10 on the gearbox 6. The other ends of the two connecting rods 10 are then slid into the two guide caps 11. The two locking caps 13 are rotated to be positioned on the two connecting rods 10. The other ends of the two connecting rods 10 are slid into the connecting holes on the two connecting plates 12. The gearbox 6 is moved so that its input sleeve 5 is fitted onto the output shaft of the motor 4. The other two locking caps 13 are then rotated so that one end is pressed against the outer wall of the connecting plate 12, so that the gearbox 6 is horizontally connected to the motor 4 and the position between the gearbox 6 and the motor 4 is fixed.
