There are many occasions where planetary reducers are used, and they are constantly updated to meet people's requirements. The following is a brief description of the classification of planetary reducers and the failures that occur during use:
1. Characteristic application of planetary reducer
1. Light appearance and structural design. The use of life-long replacement-free lubricating oil, and regardless of where it is installed, can be maintenance-free operation and fully enclosed design, and has the degree of protection of IP65, so it can also be used when the working environment is poor. Industrial robots, and automated electromechanical products.
2. Planetary reducer has the advantages of relatively compact structure, small return clearance, high accuracy, long service life, and rated output torque. But the price is slightly more expensive.
3. The servo planetary reducer provides high cost performance, wide application, economical and practical, long life and other advantages. In the application of servo control, it exerts a good servo rigidity effect, accurate positioning control, and has a medium and low on the operating platform. Backlash, high efficiency, high input speed, high input torque, smooth operation, low noise and other characteristics.
2. A brief description of the faults during the use of the planetary reducer
1. The pressure in the fuel tank rises. In the enclosed reducer, each pair of gears will produce heat when friction occurs. According to Boyle ’s law, as the operating time increases, the temperature in the reducer gradually rises. The internal volume of the reduction gear box is unchanged, so the pressure in the box increases accordingly, and the lubricating oil in the box is splashed and spilled on the inner wall of the reduction gear box. Due to the relatively high permeability of oil, under the pressure in the tank, where the seal is not tight, the oil will leak out.
2. Excessive fuel supply During the operation of the reducer, the oil sump is stirred a lot, and the lubricating oil splashes everywhere in the machine. If the fuel amount is too large, a large amount of lubricating oil will accumulate on the shaft seal, joint surface, etc., resulting in leakage.
3. Improper maintenance process During equipment maintenance, oil leakage may also be caused due to incomplete removal of dirt on the joint surface, improper selection of sealant, reverse installation of seals, and failure to replace seals in time.
4. Unreasonable structural design of the reducer causes oil leakage. If the designed reducer does not have a ventilation hood, the reducer cannot achieve pressure equalization, resulting in higher and higher pressure in the tank and oil leakage.
