Description

Technical Field

[0001] The utility model belongs to the technical field of speed reducers, and more specifically, relates to a speed reducer which is convenient for filling lubricating oil. Background Art

[0002] A reducer is an independent component consisting of a gear transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It matches the speed and transmits torque between the prime mover and the working machine or actuator. It is widely used in modern machinery. The reducer needs to be filled with lubricating oil before use to ensure that the reducer can operate normally. The lubricating oil can extend the life of the reducer, provide lubrication protection for bearings, gears and gear shafts, and can also reduce the noise of the reducer.

[0003] Based on the above, the existing reducer is more complicated to operate when adding lubricating oil, and the amount of oil added cannot be observed during filling, which leads to the disadvantage of overflowing when filling, which easily causes waste of lubricating oil. Therefore, how to more conveniently add lubricating oil to the reducer has become a new problem. Utility Model Content

[0004] In order to solve the above technical problems, the disclosed embodiment relates to a reducer that is convenient for filling with lubricating oil, so as to solve the problem that the current operation of filling with lubricating oil is cumbersome and the amount of oil cannot be observed. Holes are punched on the outer surface of the reducer and distributed in the middle and top positions of the reducer to facilitate the staff to fill the reducer with oil for maintenance. At the same time, small holes are set next to the oil filling holes to facilitate the discharge of air inside the reducer when filling with lubricating oil, thereby ensuring smooth filling of the lubricating oil. Combined with the setting of the oil plug with a window on the flange surface, it is convenient for the operator to observe the situation of filling the lubricating oil in the reducer, and prevent the situation where the lubricating oil is full and flowing out. At the same time, the window can also facilitate the staff to check the use of the reducer.

[0045] The specific usage and function of this embodiment are as follows:

[0046] In the present invention, first, holes are punched on the surface of the assembly box cover 101, which are distributed in the middle and top positions of the reducer, so that the staff can perform oil filling and maintenance on the reducer. At the same time, a small hole exhaust hole 2011 is opened next to the oil filling hole 201 to facilitate the discharge of air inside the reducer when filling the lubricating oil, ensuring smooth filling of the lubricating oil. Then, through the cooperation of the oil plug 9 on the flange surface, it is convenient for the operator to observe the filling of the lubricating oil in the reducer, preventing the lubricating oil from being filled and flowing out. At the same time, the window can also facilitate the staff to check the use of the reducer, and then only need to inject the lubricating oil into the reducer through the oil filling hole 201. Through the cooperation of the first output assembly shaft 6, the second output assembly shaft 601 and the transmission assembly shaft 7, the internal transmission parts are evenly in contact with the lubricating oil, ensuring that the reducer can operate normally. The lubricating oil can extend the life of the reducer and provide lubrication protection for the bearings, gears and gear shafts. The lubricating oil can also reduce the noise of the reducer. The key to this solution is the filling of the reducer lubricating oil. An exhaust hole 2011 is provided. The lubricating oil is relatively viscous and not easy to flow. It is easy to overflow during filling. Therefore, the exhaust hole 2011 can solve this problem. The flange surface window oil plug 9 can intuitively see the lubricating oil filling situation, which is also convenient for checking the operation and use of the reducer.
