Steel Speed Reducer Gear Box Steel Speed Speed Reducer Gear Box

Steel speed reducer gear box, reducer, both inside and outside differential pressure: reducer operation process, movement vice friction heat and influenced by environmental temperature, the temperature rise of the gearbox, if there is no breather hole or blockage in a breather hole, Steel Speed Reducer is increasing pressure on machine, Gear Box Steel Speed machine the higher the temperature, pressure difference with the outside world, the greater the oil under the action of pressure difference, the leakage from the gap. Amount to much: reducer in the process of operation, the oil pool was badly agitation, lubricating oil and splatter everywhere inside the machine, if the amount is overmuch, make a lot of lubricating oil accumulation in the place such as shaft seal, in combination with surface, lead to leakage. Steel Speed Reducer Gear Box Steel Speed Speed Reducer Gear Box

1) check that the hole cover plate is too thin, and after tightening the bolt, Steel Speed Reducer is easy to generate deformation, making the joint surface uneven and leaking oil from the contact gap;

2) during the construction of deceleration mechanism, the casting did not undergo annealing or aging treatment, and the internal stress was not eliminated, so deformation was inevitable, resulting in clearance and leakage.

3) there is no oil return groove on the box body, and the lubricating oil accumulates at the shaft seal, end cover, binding surface, etc. Under the action of pressure difference, it leaks out from the gap;

4) unreasonable design of shaft seal structure.The early reducer used oil groove, felt ring shaft seal structure, when the assembly of the felt compression deformation, and the joint surface gap seal up.If the shaft neck is not in good contact with the sealing parts, the sealing will fail in a short time due to the poor compensation performance of the felt.Although there are oil return hole in the oil groove, it is easy to block up and the oil return function is difficult to play.
