It is suggested to weigh the oil star when the reducer is out of operation and add suitable lubricating oil for worm gear reducer. Reducer manufacturers generally have instructions to specify the oil quantity of worm gear reducer, and the oil quantity should be added to 2 / 3 position of oil window.

This data is in the shutdown state, note: do not add lubricating oil when the worm gear reducer is running. Because during the operation of the worm gear reducer, the internal parts of the gear or worm gear drive the internal lubricating oil to run together. If the oil quantity of the worm gear reducer is judged in this case, it may be full, or it may be less than 2 / 3 of the oil window, or even there may be no lubricating oil. When a new reducer is in use, it needs to be replaced with new oil after 300 hours of continuous operation, and then it needs to be changed every 2500 hours. However, there are impurities, aging and deterioration in the process of use, which must be replaced at any time. Gear oil of fixed brand and number shall be used for reducer, and different brands, numbers or types of oil shall not be mixed. In the process of oil change, the internal part of the reducer should be cleaned first, and then new oil should be injected.
