Description

Technical Field

[0001] This utility model relates to the field of speed reducers, and in particular to a speed reducer oil level display mechanism. Background Technology

[0002] The working principle of a speed reducer is based on gear meshing. When the input shaft rotates, the driving gear drives the driven gear to rotate. Due to the different number of teeth on the gears, the speed of the output shaft decreases relative to the input shaft, while the output torque increases accordingly.

[0003] A speed reducer typically consists of a housing, gears, and shafts. To reduce friction between the gears and shafts, lubricant is added inside the speed reducer housing. Since the speed reducer housing is usually made of cast iron, an oil filling hole is typically opened at the top of the housing and sealed with bolts. However, due to sealing issues or mechanical failures, the amount of lubricant inside the speed reducer housing can decrease. Furthermore, the iron housing is opaque, making it difficult to observe the amount of lubricant inside the speed reducer, thus presenting a certain drawback. Utility Model Content

[0036] This utility model provides, for example Figure 1-3 The image shows a gearbox oil level display mechanism.

[0037] Example 1

[0038] The device includes a reducer housing 1, a float assembly 2, an integrated bracket 3, a transparent sleeve 4, and a cleaning assembly 5. A protruding outer shell 11 is provided on one side of the reducer housing 1, and the inner cavity of the protruding outer shell 11 is interconnected with the inner cavity of the reducer housing 1. The float assembly 2 is located inside the protruding outer shell 11 and is used to display the content of lubricating oil inside the reducer housing 1. The integrated bracket 3 is installed on the top of the protruding outer shell 11. The transparent sleeve 4 is rotatably installed on the top of the protruding outer shell 11 via the integrated bracket 3. The transparent sleeve 4 is fitted onto the top of the float assembly 2, providing protection to the float assembly 2 and preventing external dust from entering the reducer housing 1 through the connection between the float assembly 2 and the protruding outer shell 11. The cleaning assembly 5 is located on the integrated bracket 3 and is used to wipe and clean the inner wall of the transparent sleeve 4; that is, by rotating the transparent sleeve 4, the cleaning assembly 5 cleans the inner wall of the transparent sleeve 4.

[0039] Furthermore, the float assembly 2 includes a connecting rod 21, a float 22, and an indicator plate 23. The connecting rod 21 is located inside the protruding outer shell 11, and the float 22 is fixedly installed at the bottom of the connecting rod 21. The float 22 is located inside the protruding outer shell 11, and the buoyancy of the float 22 in the lubricating oil is greater than the weight of the connecting rod 21, the float 22, and the indicator plate 23. The indicator plate 23 is fixedly installed at the top of the connecting rod 21, and the indicator plate 23 is slidably fitted inside the transparent sleeve 4. By observing the height of the indicator plate 23 inside the transparent sleeve 4, the amount of lubricating oil inside the reducer housing 1 can be determined.

[0040] In particular, the integrated bracket 3 includes a base plate 31, a threaded tube 32, a top plate 33, a sealing collar 34, and a sealing gasket 35. The bottom of the base plate 31 has a through hole corresponding to the connecting rod 21. The cleaning assembly 5 is installed on the base plate 31. The threaded tube 32 is fixedly connected to the bottom of the base plate 31. The outer wall of the threaded tube 32 is threadedly connected to the protruding outer shell 11. Rotating the base plate 31 separates the threaded tube 32 from the protruding outer shell 11. Lubricating oil can also be added to the inside of the reducer housing 1 through the protruding outer shell 11. The top plate 33 is set on the base plate. The top of the top plate 33 and the bottom plate 31 are provided with grooves corresponding to the transparent sleeve 4 on opposite sides, so that the transparent sleeve 4 can rotate relative to the bottom plate 31 and the top plate 33. The sealing ring 34 is fixedly sleeved on the end of the outer wall of the transparent sleeve 4, and the sealing gasket 35 is fixedly connected to the outside of the sealing ring 34. The top plate 33 and the bottom plate 31 are provided with annular grooves matching the sealing gasket 35 on opposite sides. The sealing ring 34 and the sealing gasket 35 can improve the sealing performance between the transparent sleeve 4 and the bottom plate 31 and the top plate 33.

[0041] Furthermore, the integrated bracket 3 also includes a fixing rod 36, a fixing collar 37, and a fixing nut 38. The bottom of the fixing rod 36 is fixedly connected to the base plate 31, and the outer wall of the fixing rod 36 is slidably inserted into the top plate 33. The fixing collar 37 is fixedly sleeved on the outside of the fixing rod 36 and is located at the bottom of the top plate 33. The fixing nut 38 is threaded onto the outside of the fixing rod 36 and is located at the top of the top plate 33. The fixing nut 38 and the fixing collar 37 can ensure the stability of the top plate 33 installed on the top of the base plate 31. By removing the fixing nut 38 and taking off the top plate 33, the transparent sleeve 4 can be disassembled and replaced.

[0042] Example 2

[0043] Based on Embodiment 1, the cleaning component 5 includes a mounting rod 51 and a scraper 52. The bottom of the mounting rod 51 is fixedly connected to the base plate 31. The mounting rod 51 is located inside the transparent sleeve 4. The scraper 52 is fixedly connected to one side of the mounting rod 51. The scraper 52 is in contact with the inner wall of the transparent sleeve 4, thereby rotating the transparent sleeve 4. The scraper 52 can clean the inner wall of the transparent sleeve 4, preventing oil impurities inside the reducer housing 1 from adhering to the inner wall of the transparent sleeve 4, which would prevent the height of the indicator plate 23 from being observed through the transparent sleeve 4.
