From the perspective of proper maintenance, we need to pay attention to the following six aspects:
 
(1) For parts that are more susceptible to corrosion in the equipment, such as shaft seals, it is easy to age and wear. During the operation of the Sumitomo type cyclo, the smoothness and sealing of the two contact parts can be ensured, and the noise generated by the operation can be reduced. Regular inspection and replacement of the shaft seal is required. In addition, the wear of the shaft seal can easily cause dust or some metal powder in the working environment to enter the inside of the Sumitomo type cyclo.
 
(2) When the operating temperature of the Sumitomo type cyclo exceeds the bearing use temperature, it is necessary to stop the inspection, and carefully check whether the bearing, the gear sleeve, the faceplate, the spacer ring, the pin sleeve and other parts of the Sumitomo type cyclo are damaged, if there is a certain degree of deformation or Damage, need to be replaced in time, and also pay attention to the correct installation when replacing.
 
(3) When the Sumitomo type cyclo is working normally, the eccentric bearing is stressed, and the eccentric bearing should be replaced in time for disassembly and repair.
 
(4) When the Sumitomo type cyclo is unsealed for maintenance inspection, the installation process must be cautious and careful. After wiping the contact surface, replace the gasket with a suitable thickness with a sealant.
 
(5) The different internal structure, parts and equipment parameters of different Sumitomo type cyclo models are different. The internal parts cannot be replaced at will, or they can be used together with other Sumitomo type cyclo parts.
 
Due to the different conditions, operating environment and running time of the Sumitomo type cyclo, various faults will occur during the actual operation. The installation, use and maintenance of the Sumitomo type cyclo require strict installation and operation standards. In addition, the relevant staff should pay more attention to the advantages of the cycloidal pinwheel Sumitomo type cyclo, and improve work efficiency.

Lubrication 1. The horizontal cycloid reducer is lubricated under normal conditions by oil pool. The height of the oil surface can be kept in the middle of the oil window. Cyclic lubrication can be used when the working conditions are bad and the ambient temperature is high.
2. The Sumitomo type cyclo pinwheel reducer is generally lubricated with 40# or 50# mechanical oil at normal temperature. In order to improve the performance of the reducer and prolong the service life, it is recommended to use 70# or 90# extreme pressure gear oil in high and low temperature conditions. Lubricants should also be reconsidered during work.
3. The vertical installation of the planetary cycloid reducer should strictly prevent the oil pump from breaking oil to avoid damage to the components of the reducer.
4. When refueling, you can rotate the vent cap on the upper part of the base to refuel. When draining oil, screw the oil drain plug on the lower part of the base to release the oil. The reducer is internally free of lubricant when it leaves the factory.
5, the first refueling operation for 100 hours should be replaced with new oil, (and the internal sewage is washed clean) and then continue to work, change every six months (8-hour work system), if the working conditions are bad, the oil change time can be shortened appropriately, Lubricating oil should always be replenished during use.6, the factory's reducer has been greased, replaced every six months.

Installation 1. It is not allowed to use the direct slamming method when attaching the coupling, pulley, sprocket and other joints on the output shaft of the cycloid reducer, because the output shaft structure of the reducer cannot withstand the axial slamming force. , the shaft end screw hole can be screwed into the coupling member.
2. The shaft diameter of the output shaft and the input shaft is matched with GB1568-79.
3. The lifting eye screw on the reducer is only used for lifting the reducer.
4. When installing the reducer on the basis, calibrate the installation centerline elevation of the reducer, the level and the relevant dimensions of the connected parts. The concentricity of the calibration drive shaft should not exceed the range allowed by the coupling.
5. When the speed reducer is calibrated, it can be carried out with steel blocks or cast iron blocks. The height of the blocks should not exceed three, and it can also be carried out with the iron. However, the gears should be replaced with flat blocks after calibration.
6. The arrangement of the blocks should avoid the deformation of the body. The two sides of the foundation bolts should be arranged symmetrically. The mutual distance can be enough to allow the water slurry to circulate freely during irrigation.
7. The irrigation of cement slurry should be dense, and there should be no air bubbles, voids and other defects. The term explains the reduction ratio: the ratio of the input speed to the output speed.

Series: Number of sets of planetary gears. Generally, the maximum level can reach three, and the efficiency will be reduced.
Full load efficiency: The transmission efficiency of the reducer under the maximum load condition (fault stop output torque).
Working life: The cumulative working time of the reducer under rated load and rated input speed.
Rated torque: It is the long-running torque allowed for the rated life. When the output speed is 100 rpm, the life of the reducer is the average life. When this value is exceeded, the average life of the reducer will decrease. The gear unit fails when the output torque exceeds twice. Noise: unit decibel, this value is the input speed of 3000 rev / min, without load, measured at a distance of 1 m from the reducer. Hysteresis: The input end is fixed, the output end rotates clockwise and counterclockwise. When the output end is subjected to positive and negative 2% rated torque, the output end of the reducer is displaced by a slight angular displacement, which is the return gap.
The following are some of the gear ratios listed: single-stage gear ratio: 9, 11, 17, 23, 29, 35, 43, 59, 71, 87
Two-stage transmission ratio: 121 (11 × 11), 187 (17 × 11), 253 (23 × 11), 289 (17 × 17), 385 (35 × 11), 391 (23 × 17), 473 (43 ×11), 493 (29×17), 595 (35×17), 731 (43×17), etc.
