Cleaning up the reducer

How to make the reducer's tolerance and cleaning work?

  1. Wear of the reducer housing bearing box 2. Repair of the wear of the bearing chamber in the inner hole of the reduction box of the shearer gear shaft diameter wear of the reducer gear shaft diameter wear of the reducer gear shaft diameter wear of the reducer during long-term operation , The shaft head often wears 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 outsourcing; and the metal is repaired with metal, which cannot be changed; the hard-to-hard coordination relationship is integrated in various forces. Under the action, it will still cause wear again.

  The operation should be stable, without impact, 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, the reliability of the pressing of the fasteners, and it 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.

  After the oil is changed and cooled, 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 the transmission coupling has protrusions or adopts gears or sprockets for transmission, consider installing protective devices. When the output shaft bears a large radial load, a 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 coupling, because improper installation of this type of coupling will cause unnecessary external load, which will cause early damage to the bearing, or even break the output shaft in severe cases.

  Quickly deal with common problems of the reducer. The bearing chamber of the reducer is worn. After the problem occurs, it is difficult to solve the problem on the spot by traditional methods. It must be repaired by outsourcing. It requires a long time to stop production and waste the valuable production time of the enterprise.

  Moreover, metal is used to repair the metal, which cannot be changed; the coordination relationship between hard and hard, under the combined action of various forces, will still cause wear again.

  The polymer composite material has super adhesion, excellent compressive strength and other comprehensive performances. The use of Mega Wah polymer composite material can avoid disassembly and machining, and quickly and effectively repair the wear of the bearing chamber.

  That is to say, there is no thermal stress of repair welding, and the repair thickness is not limited. At the same time, the product has a retreat that the metal material does not have, absorbs the shock and vibration of the equipment, and avoids the possibility of wear again.

  Cut off the power to prevent electric shock! Wait for the reducer to cool down and there is no risk of burning! Note: The reducer should still be warm when changing the oil.

  Install the oil drain plug.

  Check the oil level at the oil level plug.

  Check the height of the oil level line by opening the oil level plug screw according to different installation positions. Add oil from the oil level plug until the lubricating oil overflows from the oil level plug screw hole. The test run time shall not be 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 use the assembly fixture and the internal thread of the shaft end to press the transmission parts in with bolts, otherwise it may cause damage to the internal parts of the reducer.

  The reducer adopts oil pool splash lubrication. Before running, the user needs to remove the screw plug of the vent hole and replace it with the vent plug.

  The foundation is unreliable, which will cause vibration and noise during operation, and cause damage to bearings and gears.

  Inject new oil of the same brand.

  Precautions 1. The reducer should be firmly installed on a stable level foundation or base, the oil in the oil drain groove should be able to be drained, and the cooling air circulation should be smooth.

  2. Install the device according to the regulations to ensure that the staff can easily approach the oil mark, vent plug and oil drain plug.

  Good alignment can prolong service life and obtain ideal transmission efficiency
