Today, I would like to share with you the key points of installation, use and maintenance of cylindrical gear reducer.
1. The input shaft axis and output shaft axis of the reducer and the axis of its connecting part shall be coaxial, and the error shall not be greater than the allowable value of the coupling used.
2. After installation, the required lubricating oil must be injected into the tank oil pool, and the oil level shall be as high as the height between the upper and lower limit scribed lines specified by the oil dipstick.
3. Before the reducer is officially used, it must be rotated by hand flexibly without jamming, and then it shall be operated without load for no less than 2 hours. The operation shall be stable without impact, vibration, noise and oil leakage. Any fault shall be eliminated in time.
4. When the new reducer is used for the first time, it must be replaced with new lubricating oil after 20 days of operation. In future use, the quality of oil shall be checked regularly. If impurities or aged and deteriorated oil are found, it must be replaced at any time. At the same time, the oil level height shall be checked frequently. If it is lower than the specified height, it shall be supplemented in time. In general, the oil of the reducer working continuously for a long time must be changed once every three months. For the reducer whose working time does not exceed eight hours a day, the oil must be changed every six months.
5. When the oil temperature rises significantly, exceeds 60 ℃ or 85 ℃, and abnormal noise is generated during use, the use shall be stopped and the causes shall be checked. If it is caused by tooth surface gluing and other reasons, it must be repaired, the fault shall be eliminated, and the lubricating oil shall be replaced before use.
6. If serious oil leakage or oil leakage is found on the joint surface during use, open the machine cover and apply 601 sealant. If oil leakage is found, replace the oil seal according to the original oil seal model.
7. Due to the characteristics of hard tooth surface and thin input shaft, it is generally difficult to use belt pulley for connection and speed change. If belt transmission is really required, consult the technical department of the manufacturer.
Use and maintenance of planetary gear reducer
1、 Installation requirements
1. Elastic coupling, gear coupling or other non rigid coupling shall be adopted for the connection between planetary gear reducer, motor and working machine. Nylon pin coupling is generally recommended. It has the characteristics of compact structure, easy manufacture, safety and reliability and convenient maintenance. The manufacturer can supply nylon pin coupling according to the needs of users and leave the factory together with the reducer.
2. The installation error rate difference of planetary gear reducer shall not be greater than the allowable value of the coupling used.
3. After the reducer is installed, adjusted and aligned, the anchor bolts must be fixed on the foundation or base.
4. After the reducer is installed, it must rotate flexibly by hand without jamming.
2、 Lubrication
1. The reducer has two types: oil pool lubrication and circulating lubrication. For the reducer with high ambient temperature, high power, fast speed or continuous operation, circulating lubrication shall be adopted as far as possible to reduce the oil temperature and give full play to the bearing capacity of the reducer.
2. Replacement period of lubricating oil:
When a new reducer (or newly replaced gear) is used for the first time, replace the lubricating oil after 10-15 days of operation. Under normal conditions, the lubricating oil of the reducer working continuously 24 hours a day shall be replaced no more than three months; For reducers that work less than 10 hours a day, the lubricating oil shall be changed no more than six months.
3、 Maintenance
1. During operation, when the oil temperature rises significantly and exceeds 80 ℃, the quality of the oil deteriorates and abnormal noise is generated, it shall be stopped and the lubricating oil shall be replaced no more than six months.
2. A protective shield shall be installed on the extended shaft end and coupling of the reducer.
3. The reducer shall be inspected once within half a year, and the spare parts must be manufactured according to the drawing requirements. The reducer replaced with spare parts must be solid and can be officially used only after running in and load test run.
4. The reducer shall always be kept clean, and the exposed surface shall not accumulate dust and dirt to avoid affecting the heat dissipation.
The above is the knowledge introduced to you. I hope you can refer to it.
