Reasons for oil leakage in the reducer oil tank of the no-gravity mixer

In recent years, the reducer has played an important role in the industry. After the reducer has been updated, the performance has become more comprehensive. Now there are many types of reducers available on the market. The weightless mixer reducer is a relatively new type of reducer, which has been recognized since it was used. However, the unavoidable defect of the weightless mixer reducer is that there is oil leakage in the fuel tank. In this article, the editor will take you to understand the reasons. 1. When the reduction gear box is working, the friction generated by the meshing of each pair of gears in the box will emit heat, and with the increase of the operation time of the reduction gear box, the temperature in the reduction gear box box will rise, the gas will expand, and the The volume remains unchanged. If the vent cap on the top of the box is not opened, the thermal expansion air in the box can be freely discharged to maintain the pressure balance inside and outside the box, otherwise the lubricating oil will leak along the sub-box surface or other gaps such as shaft extension seals. 2. The structure design of the reduction gear box is unreasonable, and there is no ventilation cap. The inspection hole cover is too thin, the joint surface is uneven, and oil leaks from the contact gap; during the manufacturing process of the reduction gear box, the castings are not annealed and aged, and after deformation, the oil will be exposed from the generated gap; In the oil return tank, the lubricating oil will accumulate in the shaft seal, end cover, joint surface, etc. Under the action of the pressure difference, the lubricating oil will leak from the gap. These are the reasons that may cause oil leakage in the reducer oil tank of the weightless mixer. You can understand that when there is an oil leakage, you can simply judge which cause is caused, so that you can quickly know the solution. direction. What else do you want to know, you can leave a message to the editor, and the editor will answer it for you. There are still many brands of weightless mixer reducer. There are many advantages to choose a large brand of weightless mixer reducer.
