Pitting and spalling of the tooth surface mostly occur at the top of the tooth above the middle of the height. Part of the gear broken teeth of the reducer is caused by manufacturing quality defects. During the operation of the gear, because the teeth are squeezed by high pressure, a very small crack is formed on the tooth surface first, and then the crack develops into a shallow pit, which is the pitting of the tooth surface. For surface carburized gears, if the hardness of the gear core is insufficient, the carburized layer is too thin and the surface strength is not enough, plastic deformation of the core transition layer is likely to occur after load, so that the carburized layer will appear deeper and larger than pitting. Dimples, that is, the tooth surface peels off. The reducer is an important transmission device that connects the motor and the host equipment. It is widely used in cement production lines. Especially the application of large reducers is not uncommon. There are vertical roller presses, tube mill reducers, etc., which can be said to be large reducers. It is the key equipment that drives the operation of the cement production line.
(Note: cut off the power supply of the transmission device to prevent unintentional power on!) One E installation 1E cylindrical gear reducer generally needs to be installed on a horizontal surface with an inclination not exceeding 10°. If the inclination is greater than 10° due to special needs, please use it before use Contact with our company to discuss related matters together. When 2E input shaft and output shaft are connected with power and supporting machinery, if the coupling is used, the shaft and the shaft are required to be strictly aligned, and there should be no misalignment. Use a V-belt And the chain should not be too tight or too loose. When rotating, it will drive the internal lubricating oil to run together. If the amount of oil in the worm gear reducer is judged in this case, it may be full or lower.
The installation position of the reducer should ensure the operation of the staff, including the position where the air plug and the oil drain plug can be easily connected. After the installation of the reducer is completed, the inspector should comprehensively check the accuracy of the installation position in order to determine the reliability of each fastener.
The shaft seal structure is unreasonable. The late multi-reducer adopts the oil groove felt ring type shaft seal structure. When the group reducer is removed, the felt is compressed and deformed, and the gap of the separation surface is sealed. If the contact between the journal and the seal is not very illusory, because the compensation function of the felt is extremely poor, the seal is short
#Step is to confirm whether the motor and reducer are intact before installation and disassembly, and strictly check whether the dimensions of the parts connecting the motor and the reducer can be matched, where the fixed input shaft of the motor and the reducer groove are the same size and common service. The planetary reducer provides the advantages of high cost performance, long service life, etc. It has the characteristics of low and medium backlash, high efficiency, high input speed, high input torque, smooth operation, and low noise on the operating platform.

For vertically mounted reducers, in view of the fact that the lubricating oil may not be able to reliably lubricate the upper bearings, additional lubrication measures are adopted. Before running, inject an appropriate amount of lubricating oil into the reducer. The reducer is usually equipped with an oil filling hole and an oil drain plug. Therefore, the installation location must be specified when ordering the reducer. The working oil temperature cannot exceed 80°C. The life-time lubricated combination reducer is filled with synthetic oil in the manufacturer. In addition, the reducer is usually supplied without lubricating oil, with an oil filling plug and an oil drain plug. The quantity of lubricating oil for the reducer listed in this catalog is only an estimate. Under the condition that the reducer has been combined with the first type and the hard tooth surface gear is used — Ningbo Zhongda Leader Intelligent Transmission Co., Ltd.
