How to deal with the tolerance and cleaning of the reducer?
1. Wear of the bearing housing of the reducer housing 2. Wear of the bearing chamber of the inner hole of the reducer casing of the shearer , the shaft head is often worn out and the keyway is damaged. After the problem occurs, the traditional method is difficult to solve on the spot, and it must be repaired by external cooperation; and the metal is repaired with metal, which cannot be changed; Under the action, it will still cause wear again.
The operation should be stable, without shock, vibration, noise and oil leakage. Any abnormality should be eliminated in time.
After the installation is in place, the accuracy of the installation position should be comprehensively checked in order, and the reliability of each fastener should be able to rotate flexibly after installation.
The amount of oil should be consistent with the installation position.
Open the oil level plug, breather and oil drain plug.
Oil replacement After cooling, the viscosity of the oil increases and it is difficult to drain the oil. The reducer should be changed at the operating temperature.
Place an oil pan under the oil drain plug.
Tighten the oil level plug and breather.
When there are protrusions in the transmission coupling or gears and sprockets are used for transmission, protective devices should be installed. When the output shaft bears a large radial load, the reinforced type should be selected.
3. When installing the reducer, attention should be paid to the centering of the transmission center axis, and the error should not be greater than the compensation amount of the coupling used.
It is best not to use rigid fixed couplings. Improper installation of such couplings will cause unnecessary external loads, resulting in early damage to the bearing, and even breakage of the output shaft in severe cases.
Quickly deal with common problems of reducer Bearing chamber wear of reducer Bearing chamber of reducer is worn out. After the problem occurs, it is difficult to solve on-site by traditional methods. It must be repaired by external assistance, which requires long-term shutdown and waste of precious production time.
Moreover, the metal is repaired with metal, which cannot be changed; the matching relationship between hard and hard will still cause re-wear under the combined action of various forces.
The polymer composite material has comprehensive properties such as super adhesion and excellent compressive strength. The use of Meijiahua polymer composite material can be free of disassembly and machining, and can quickly and effectively repair the bearing chamber wear.
That is, there is no thermal stress of repair welding, and the repair thickness is not limited. At the same time, the metal material of the product does not have the concessional property, which absorbs the shock and vibration of the equipment and avoids the possibility of wear and tear again.
The polymer composite material has comprehensive properties such as super adhesion, excellent compressive strength, etc.
Cut off the power supply to prevent electric shock! Wait for the reducer to cool down until there is no danger of burning! Note: The reducer should remain warm when changing the oil.
Install the oil drain plug.
Check the oil level at the oil level plug.
According to different installation positions, open the oil level plug screw to check the height of the oil level line, add oil from the oil level plug until the lubricating oil overflows from the oil level plug screw hole, screw on the oil level plug to confirm that it is correct, and then empty it. Load test run, time not less than 2 hours.
Drain all the oil.
After a certain period of time, the oil level should be checked again to prevent possible leakage from the casing. If the ambient temperature is too high or too low, the grade of the lubricant can be changed.
4. When installing the transmission parts on the output shaft, it is not allowed to hit with a hammer. Usually, the assembly fixture and the internal thread of the shaft end are used to press the transmission parts with bolts, otherwise it may cause damage to the internal parts of the reducer.
The reducer is lubricated by splashing oil pool. Before running, the user needs to remove the screw plug of the vent hole and replace it with a vent plug.
The foundation is unreliable, causing vibration and noise during operation, and causing damage to bearings and gears.
Inject new oil of the same brand.
Precautions 1. The reducer should be firmly installed on a stable and level foundation or base, the oil in the oil drain tank should be able to be drained, and the cooling air circulation should be smooth.
2,According to the specified installation device, the staff can easily get close to the oil mark, breather plug and oil drain plug.
Good alignment extends service life and achieves ideal transmission efficiency
