1. For the reducer with oil level plug

Check the oil level, whether it is qualified; install the oil level plug. Gear manufacturers

2. Oil replacement

After cooling, the viscosity of the oil increases, and it is difficult to drain the oil. The reducer should be changed at the operating temperature. Cut off the power to prevent electric shock! Wait for the gear unit to cool down until there is no danger of burning!

3. Matters needing attention

Inject new oil of the same brand; the amount of oil should be consistent with the installation position; check the oil level at the oil level plug; tighten the oil level plug and breather; the reducer should remain warm when changing the oil; Put an oil pan below; open the oil level plug, breather and oil drain plug; drain all the oil; install the oil drain plug.

Fourth, the inspection of the oil level

The structure of the gear shaft

Cut off the power to prevent electric shock! Wait for the reducer to cool; remove the oil level plug to check whether the oil is full; install the oil level plug.

Five, oil inspection

Cut off the power to prevent electric shock! Wait for the reducer to cool; open the oil screw plug and take an oil sample; check the viscosity index of the oil; if the oil is obviously cloudy, it is recommended to replace it as soon as possible.

Arc gear reducer is a common type of reducer, which has great advantages in structure and transmission ratio, especially in certain conditions, it can use the self-locking function, so it is very popular among users. There are four common problems of arc gear worm reducer, which are the heat and oil leakage of the reducer, the wear of the worm gear of the reducer, and the damage of the bearing of the reducer.

1. Heating and oil leakage of the arc gear reducer The arc gear worm gear reducer is designed for the purpose of improving operating efficiency. The worm gears used are all non-ferrous metals as the main material, and the worms mostly use hard steel. During the operation of the sliding friction drive, the worm gear reducer will generate a large amount of heat, which will increase the temperature of the reducer. The temperature increase of the worm gear reducer will cause the various parts in the reducer to have differences in the fit due to the different coefficients of thermal expansion, resulting in a gap between the mating surfaces. The oil such as lubricating oil used in the reducer will also become thinner or deteriorated under the action of high temperature, resulting in leakage or lubrication failure. The way to prevent the temperature rise of the worm gear reducer is to reasonably match the material of the worm gear and worm to avoid excessive friction. At the same time, pay attention to the surface quality of the meshing friction surface and select suitable lubricants. Another direct way to cool the reducer is to install a cooling device or reduce the temperature of the operating environment.

2. The worm gear of the arc gear reducer is worn out. The worm gear of the worm gear and worm gear reducer is generally made of tin bronze as the main material, and the worm is made of hard steel. The worm gear and the worm keep friction during the operation of the reducer, and the worm gear with a softer material Wear will occur due to the action of the worm. The wear rate of the worm gear reducer is very slow, which usually does not reduce the service life of the reducer. If the wear rate is fast, the selection, operation, material matching and lubrication of the worm gear reducer of the reducer should be considered. There is a problem.

3. Damage to the worm bearing of the reducer The damage to the worm bearing of the worm gear reducer is mainly manifested by rust and corrosion of the bearing. The main reason for this problem is the lack of lubrication of the inward gear or the emulsification of the gear oil. lubrication failure. After the worm gear reducer stops running, the gear oil will be emulsified due to the condensed water generated by cooling.
