Heating and oil leakage faults of helical gear reducer and their causes

As a commonly used transmission device, helical gear reducer has a wide range of applications in the industrial field. However, in actual use, helical gear reducers may experience malfunctions such as heating and oil leakage, which can affect their normal operation and lifespan. This article will analyze the causes of heating and oil leakage faults in helical gear reducers, in order to provide useful references for users.

1、 Heating fault and causes of helical gear reducer
During the operation of a helical gear reducer, a certain amount of heat is generated due to friction between internal gears, bearings, and other components. Under normal circumstances, the gearbox dissipates heat through a cooling device to maintain its internal temperature within the normal range. However, when the gearbox experiences a heating fault, its internal temperature will abnormally rise, which may lead to component damage in severe cases. The main causes of heating faults are as follows:

1. Insufficient or deteriorated lubricating oil: Lubricating oil plays a role in lubrication, cooling, and cleaning in the gearbox. When the lubricating oil is insufficient or deteriorated, the friction coefficient increases, resulting in excessive heat generation.

2. Poor gear meshing: Poor gear meshing may be caused by low gear machining accuracy, assembly errors, and other reasons. Gears with poor meshing will generate additional frictional heat during operation.

3. Bearing damage: Bearing damage can cause unstable operation and generate additional frictional heat.

4. Malfunction of heat dissipation device: Malfunction of heat dissipation devices such as fans, radiators, etc. can lead to poor heat dissipation effect of the gearbox, resulting in heating failure.

2、 Oil leakage fault and causes of helical gear reducer
Oil leakage is another common fault in helical gear reducers. Oil leakage not only reduces the amount of lubricating oil, but may also pollute the environment, and in severe cases, may cause safety accidents. The main reasons for oil leakage faults are as follows:

1. Aging or damage of seals: Seals inside the gearbox, such as oil seals, O-rings, etc., are prone to aging or damage after prolonged use, leading to lubricant leakage from the seals.

2. Damage to fuel tank or oil pipe: Fuel tank or oil pipe may crack or break due to external impact or long-term wear, leading to oil leakage.

3. Overfilling of lubricating oil: When too much lubricating oil is added, the pressure in the oil tank will increase, which may cause the lubricating oil to leak from the seal.

4. Improper installation: If the reducer is not adjusted and fixed according to the requirements during installation, it may cause uneven stress on the seals, leading to oil leakage faults.

3、 Preventive measures for faults
To reduce the risk of heating and oil leakage in helical gear reducers, the following preventive measures can be taken:

1. Regularly check the lubricating oil: Regularly check the oil level and quality of the lubricating oil to ensure that it is sufficient and has not deteriorated. If insufficient or deteriorated lubricating oil is found, it should be added or replaced in a timely manner.

2. Maintain the good condition of gears and bearings: Regularly inspect and maintain gears and bearings to ensure smooth operation and no abnormal wear.

3. Pay attention to the maintenance of the heat dissipation device: Regularly check the working condition of the heat dissipation device to ensure its good heat dissipation effect. If a malfunction is found in the heat dissipation device, it should be repaired or replaced in a timely manner.

4. Proper installation and use of the reducer: When installing and using the reducer, follow the requirements provided by the manufacturer to ensure correct and stable installation of the reducer.

In short, helical gear reducers may experience malfunctions such as heating and oil leakage during use. By analyzing the causes of these faults and taking corresponding preventive measures, the risk of faults can be effectively reduced and the service life of the gearbox can be extended. At the same time, when users encounter these faults, they should also take corresponding maintenance measures according to the actual situation to restore the normal working state of the gearbox.
