Description

Gear reducer with lubricating structure on box body

Technical Field

The utility model relates to a mechanical transmission technical field particularly, relates to a gear reducer that box has lubricating structure.

Background

In the structure of the speed reducer, a high-speed shaft of the speed reducer is rotatably arranged on a case through a bearing, and the bearing is used for supporting the high-speed shaft, reducing the friction resistance received in the rotating process of the high-speed shaft and reducing the abrasion. Typically, bearings are provided at both ends of the high speed shaft. In order to ensure the reliability of the operation of the high-speed shaft, the bearing on the high-speed shaft needs to be lubricated to reduce the internal friction and the abrasion of the bearing, and meanwhile, the bearing is cooled to prevent burning and sticking and prolong the service life of the bearing.

The inside of the speed reducer is usually provided with lubricating oil which can lubricate the bearing on the high-speed shaft; however, when the speed reducer is used at an angle, namely, when the speed reducer is installed at an angle, lubricating oil cannot ensure reliable lubrication of a bearing at a high position on the high-speed shaft, namely, a high-position bearing, so that an additional lubricating structure needs to be adopted, a lubricating pipeline is exposed outside the speed reducer, damage or collision easily occurs, the condition of leakage of the lubricating oil can occur in a serious situation, and the lubrication of the high-position bearing is influenced.

An effective solution to the problems in the related art has not been proposed yet.
