Description

Technical Field

[0001] The utility model belongs to the technical direction of speed reducers, and particularly relates to a speed reducer which is easy to lubricate. Background Art

[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is commonly used as a reduction gear between a prime mover and a working machine. It matches speeds and transmits torque between the prime mover and the working machine or actuator, and is widely used in modern machinery.

[0003] When the reducer is used for a long time, the internal components will be worn. In order to extend the service life of the reducer and improve its efficiency, it is necessary to add lubricating oil to the reducer. After long-term use, impurities will be mixed inside the lubricating oil, so the lubricating oil needs to be replaced.

[0004] When replacing the lubricating oil of a traditional reducer, the oil outlet needs to be disassembled, and then the original lubricating oil needs to be discharged and new lubricating oil needs to be injected. However, due to the precipitation of impurities in the previous lubricating oil, the oil outlet is easily blocked, affecting the oil output efficiency. This phenomenon has become a problem that needs to be solved urgently by people in this field. Utility Model Content

[0007] The utility model further describes that a fixing sleeve is fixed to the outside of the outer shell, the fixing sleeve is a hollow structure, the outer sleeve of the fixing sleeve is provided with a mounting sleeve, the inside of the mounting sleeve is fixed with an inner shaft, the inner shaft is fixedly connected to the dredging rod, and the inner shaft is threadedly connected to the inner wall of the fixing sleeve.

[0008] The present invention further describes that a square groove is provided below the fixing sleeve.

[0009] The present invention further describes that the fixing sleeve is T-shaped, a cavity is provided inside the mounting sleeve, the inner shaft is provided in the middle of the cavity, and the T-shaped portion of the fixing sleeve is provided inside the cavity.

[0019] The following is a non-limiting detailed description of the technical solution of the present invention in conjunction with preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0020] See also Figure 1-3 The utility model provides a technical solution: a reducer that is easy to lubricate, including a shell 1 and a dredging rod 8. An oil inlet is provided at the top of the shell 1, an oil inlet plug 3 is provided on the oil inlet, an oil outlet 10 is provided at the bottom of the shell 1, the dredging rod 8 is provided inside the oil outlet 10, and a plurality of cleaning strips 9 are fixed on the outer side of the dredging rod 8.

[0021] A fixing sleeve 5 is fixed to the outside of the outer shell 1. The fixing sleeve 5 is a hollow structure. The outer sleeve of the fixing sleeve 5 is provided with a mounting sleeve 4. An inner shaft 7 is fixed to the inside of the mounting sleeve 4. The inner shaft 7 is fixedly connected to the dredging rod 8. The inner shaft 7 is threadedly connected to the inner wall of the fixing sleeve 5.

[0022] A square groove 6 is provided below the fixing sleeve 5 .

[0023] The fixing sleeve 5 is T-shaped. A cavity 11 is provided inside the mounting sleeve 4 . The inner shaft 7 is provided in the middle of the cavity 11 . The T-shaped portion of the fixing sleeve 5 is provided inside the cavity 11 .

[0024] A sealing gasket 1 2 is fixed to the side of the mounting sleeve 4 close to the housing 1 , and a sealing gasket 2 12 is fixed to the contact point between the mounting sleeve 4 and the fixing sleeve 5 , for increasing the sealing performance between the mounting sleeve 4 and the fixing sleeve 5 .

[0025] The length of the second sealing gasket 12 is greater than that of the square groove 6, which further increases the sealing performance and prevents the leakage of lubricating oil.

[0026] Working principle:

[0027] When it is necessary to change the lubricating oil for the speed reducer, open the oil inlet plug 3, then rotate and open the mounting sleeve 4, so that the inner shaft 7 cooperates with the fixed sleeve 5, and control the mounting sleeve 4 to move away from the outer shell 1, so that the inner shaft 7 does not block the square groove 6, then it is convenient for the oil in the outer shell 1 to flow out from the oil outlet 10. Since the T-shaped part of the fixed sleeve 5 is arranged inside the cavity 11, the mounting sleeve 4 will not be lost, which overcomes the problem of easy loss when the nut of the oil outlet is removed in the prior art.

[0028] When the mounting sleeve 4 moves in the direction away from the outer shell 1, it simultaneously drives the dredging rod 8 to move in the oil outlet 10. Since a number of cleaning strips 9 are fixed to the outer side of the dredging rod 8, when the dredging rod 8 rotates with the inner shaft 7, the impurities on the oil outlet 10 can be stirred away by the cleaning strips 9, so that the impurities flow out with the lubricating oil, thereby preventing the precipitated impurities from blocking the oil outlet 10.
