The reducer is a kind of transmission equipment used for low speed and high torque, which uses the speed converter of the gear to reduce the number of revolutions of the motor (motor) to the required number of revolutions, and obtains a large torque organization. Its main function is to reduce the speed and improve the output torque at the same time, and the torque output share is multiplied by the reduction ratio of the motor output, but it cannot exceed the additional torque of the reducer. In addition, attention should also be paid to the daily operation, protection, maintenance and other matters of the reducer.
1. Check the reducer: (1) the reliability of the fastening of each fastener; (2) Whether the oil level of the lubricating oil meets the requirements; (3) Whether the wiring of the oil supply pump is correct; (4) Whether the coupling protective cover, grounding wire and other protective equipment are installed.
2. Test operation of the reducer: (1) After the completion of the reducer device, the no-load test run should be carried out according to the operating speed, and the time should be about 2 hours; (2) After 2 hours of operation, it can be loaded and tested step by step according to the load of 25%, 50% and 75% until it runs at full load; (3) After the load runs for a period of time, the contact of the tooth surface and whether the fasteners are loose should be checked.
3. Lubrication of the reducer: (1) The reducer is uniformly used with heavy-duty industrial gear oil, and the new oil replaced must be the same as the original oil trademark, and the unnecessary trademark should not be mixed with different types of oil; (2) The lubricating oil should be replaced from scratch after the initial operation of the reducer to 400 hours, and the subsequent oil change interval is about 4000 hours; (3) The satisfactory amount of lubricating oil should be kept in the box, and the height of the oil level should be at 1/2 of the oil standard, and checked regularly.
Matters to be paid attention to when using the reducer: (1) Do not apply pressure to the output parts and boxes of the reducer during the installation, and meet the corresponding requirements of coaxiality and straightness between the machine and the reducer when connecting; (2) All reducers are strictly forbidden to start with load, and it is necessary to go through running-in and load test after replacing parts before they can be used normally; (3) During the use of the reducer, pay close attention to the rotation flexibility of each transmission part, and tell the maintenance personnel in time about the abnormal sound and high temperature phenomenon found in the process of use; (4) Inspect the reducer in operation once an hour, and pay attention to the oil supply of the oil pump (vertical cycloid reducer). The reducer with high oil temperature and tubing cracking should be inspected; (5) In order to make the reducer easy to dissipate heat, the surface should be kept clean, and the dust and dirt should be removed in time to facilitate heat dissipation; (6) The problems found in the operation of the reducer should be recorded in detail and carefully.
