Gear reducer oil seal bearing service life

The oil seal effect in the gear reducer is simply used to seal the oil, the purpose is to prevent the oil inside the reducer from leaking out. Oil is a liquid substance required in the transmission system of the reducer, so the effect of the oil seal on the reducer is to ensure that the oil does not leak. The common oil seal types are divided into single type and assembled type. The output and input ends of the reducer are equipped with oil sealing equipment. As the reducer operates for a longer time, the oil temperature also increases.

The oil seal can protect the bearing and oil leakage of the reducer, and then keep the oil used in the gear reducer normal. Oil is a liquid substance, it is volatile, and the higher the temperature, the faster it evaporates. The oil quality and life of the gear reducer are directly related to the quality of the oil seal. Therefore, a good quality oil seal can improve the working time and life of the reducer.

On the other hand, the oil seal also prevents the waste of resources and the increase of costs. The gear reducer sometimes leaks oil. In the closed space of the reducer, each pair of gears in the gear reducer will emit a lot of heat when meshing. With the continuous increase of operating time, the temperature in the reducer will gradually increase. raised, while the internal volume of the gear box is fixed.

In this way, the pressure in the reduction box will increase, and the oil permeability inside the reduction box is relatively strong, and where the seal is not tight, the oil can seep out from there. The second reason may be the unreasonable structural design of the reducer, which may cause oil leakage from the gear reducer. For example, if a certain type of reducer does not have a ventilation hood during the design, the reducer cannot achieve pressure equalization, resulting in higher and higher pressure in the box. Oil leaks will occur at this time.

The cover operation of the reducer was perfunctory, and the danger of oil leakage of the reducer was not recognized. The structure of the reducer was well designed, and the effect of oil leakage occurred. When selecting a gear reducer, the quality of the oil seal and its structure are one of the things that need to be understood in the selection of the reducer.
