Technical Field

[0001] This utility model relates to the field of speed reducer technology, specifically a gear reducer that can be quickly installed. Background Technology

[0002] Gear reducers are a common type of transmission device that uses gears of various stages to reduce speed. A reducer is composed of gears of various stages. For example, using a small gear to drive a large gear can achieve a certain degree of speed reduction. By using a multi-stage structure, the rotational speed can be greatly reduced.

[0003] Most gear reducers commonly found on the market today have similar overall structures, generally consisting of two housings, with several sets of shafts and transmission gears installed inside. However, they have some functional shortcomings in actual use and have room for improvement. For example, the reducer and motor are usually connected by a flange. During installation, the front flange of the motor is aligned with the flange of the reducer, and then bolts and nuts are driven in one by one to tighten them. This operation is quite cumbersome and does not provide a convenient and quick installation function.

[0004] Now, a novel, quick-installable gear reducer is proposed to solve the above problems. Utility Model Content

[0010] As a further technical solution of this utility model, the first bolt rod and the second bolt rod have the same specifications and are arranged at equal intervals.

[0011] As a further technical solution of this utility model, an oil inlet is fixedly connected to the middle position of the top of the upper shell, and a dust cover is sleeved on the top of the oil inlet. A distribution tube is fixedly connected to the middle position of the top of the inner part of the upper shell, a first dropper is fixedly connected to the front end of the distribution tube, and a second dropper is fixedly connected to the rear end of the distribution tube.

[0016] (1) By setting a lower half flange, a first bolt rod, an upper half flange, and a second bolt rod, when in use, the output end of the motor is inserted into the slot at the rear end of the input shaft.

The old lubricating oil is drained through the oil drain pipe by the air pressure. After draining, new lubricating oil can be added, and then the first sealing cap and the second sealing cap can be tightened to keep the housing closed, thus realizing the function of facilitating the draining of the old oil inside.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Please refer to Figure 1-6 A quick-installation gear reducer includes a lower housing 1, an upper housing 2 fixedly connected to the top of the lower housing 1, an input shaft 3 located on the right side inside the lower housing 1, a first gear 4 fixedly connected to the outside of the input shaft 3, a central shaft 5 movably connected to the middle position inside the lower housing 1, a second gear 6 and a third gear 7 fixedly connected to the outside of the central shaft 5, an output shaft 8 located on the left side inside the lower housing 1, a fourth gear 9 fixedly connected to the outside of the output shaft 8, and mounting components for quick motor installation located at the rear ends of the lower housing 1 and the upper housing 2.

[0028] Please see Figure 1-6 A gear reducer that can be quickly installed also includes a mounting assembly, which includes a lower flange 10, which is fixedly connected to the right side of the rear end of the lower housing 1. Multiple sets of first bolt rods 11 are welded to the rear end of the lower flange 10. An upper flange 12 is fixedly connected to the rear end of the upper housing 2. Multiple sets of second bolt rods 13 are fixedly connected to the rear end of the upper flange 12. A motor output port 23 is provided at the rear end of the input shaft 3.

[0029] The lower flange 10 and the upper flange 12 are the same size. The vertical planes at the rear ends of the lower flange 10 and the upper flange 12 are the same. The inner diameter of the flange formed by the lower flange 10 and the upper flange 12 is larger than the outer diameter of the input shaft 3. The input shaft 3, the lower flange 10 and the upper flange 12 do not contact each other. The first bolt rod 11 and the second bolt rod 13 are the same size. The first bolt rod 11 and the second bolt rod 13 are arranged at equal intervals to facilitate the quick installation of the motor.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the motor end flange directly fits the lower half flange 10 and the upper half flange 12. The first bolt rod 11 and the second bolt rod 13 pass through the bolt holes on the motor flange, and the bolts can be driven in directly, which makes the installation speed relatively fast.

[0031] An oil inlet 14 is fixedly connected to the middle position of the top of the upper housing 2. A dust cover 15 is fitted onto the top of the oil inlet 14. A distribution tube 16 is fixedly connected to the middle position of the top inside the upper housing 2. A first dropper 17 is fixedly connected to the front end of the distribution tube 16. A second dropper 18 is fixedly connected to the rear end of the distribution tube 16. The dust cover 15, the distribution tube 16, the first dropper 17, and the second dropper 18 are internally connected. The oil inlet 14 and the dust cover 15 are threaded together for easy lubrication and maintenance.

[0032] Specifically, such as Figure 1 and Figure 3 As shown, unscrew the dust cover 15, press the oil gun against the oil inlet 14 and start injecting lubricating oil. The lubricating oil enters the first dropper 17 and the second dropper 18 along the distribution tube 16. The oil at the first dropper 17 drips onto the meshing point of the first gear 4 and the third gear 7, and the oil at the second dropper 18 drips onto the meshing point of the second gear 6 and the fourth gear 9.

[0033] An oil drain pipe 19 is fixedly connected to the bottom left side of the lower housing 1. A first sealing cap 20 is threadedly connected to the left side of the oil drain pipe 19. An air intake pipe 21 is fixedly connected to the bottom right side of the lower housing 1. A second sealing cap 22 is threadedly connected to the top of the air intake pipe 21. The lower housing 1, the oil drain pipe 19, and the air intake pipe 21 are internally connected. The oil drain pipe 19 and the air intake pipe 21 have the same diameter.

[0034] Specifically, such as Figure 1 and Figure 5 As shown, before adding new lubricating oil, the old oil inside can be drained, the first sealing cap 20 and the second sealing cap 22 can be opened, the air pump can be connected to the air inlet pipe 21, and air can be continuously pumped into the housing through the air inlet pipe 21. The old lubricating oil can be drained through the oil drain pipe 19 by the air pressure. After draining, new lubricating oil can be added, and then the first sealing cap 20 and the second sealing cap 22 can be tightened to keep the housing closed.

[0035] Working Principle: In use, the motor's output end is first inserted into the slot at the rear end of the input shaft 3. The input shaft 3 rotates, driving the first gear 4 to rotate. The first gear 4 meshes with the third gear 7, driving the intermediate shaft 5 and the second gear 6 to rotate continuously. The second gear 6 meshes with the fourth gear 9, driving the output shaft 8 to rotate continuously. During motor installation, the end flange directly fits against the lower flange 10 and the upper flange 12. The first bolt rod 11 and the second bolt rod 13 pass through the bolt holes on the motor flange, and the bolts are directly driven in, resulting in a relatively fast installation speed. Regular lubrication and maintenance of the reducer is performed by unscrewing the dust cover 15 on the oil inlet 14, pressing the oil gun against the oil inlet 14, and starting to inject lubricating oil. The lubricating oil flows along the distribution pipe 16 into the first dropper 17 and the second dropper 18. The oil at the first dropper 17 drips onto the meshing point of the first gear 4 and the third gear 7, and the oil at the second dropper 18 drips onto the meshing point of the second gear 6 and the fourth gear 9. Before adding new lubricating oil, the old oil inside can be drained. Open the first sealing cap 20 and the second sealing cap 22, connect the air pump to the air inlet pipe 21, and continuously pump air into the housing through the air inlet pipe 21. The old lubricating oil is discharged through the oil drain pipe 19 by the air pressure. After discharge, add new lubricating oil, and then tighten the first sealing cap 20 and the second sealing cap 22 to keep the housing closed.
