In the lubricating oil of oil cylinder.When motor is inoperative, the adjustment screw center line of lubricating oil pasta and guide bearing in upper oil cylinder is horizontal
With high, but when large-size asynchronous motor high speed rotation, thrust collar in the oil also high speed rotation is soaked, because of the viscosity of oil, lubricating oil
There is also rotation identical with motor rotation speed, lubricating oil pasta is no longer horizontal with height, but outer high, interior low parabolic occurs
Shape pasta, so that the oil at thrust bearing and top guide bearing is reduced, frictional heating heat gathers, and leads to thrust bearing and guide bearing
Temperature increase in addition tile kilning.In addition, the lubricating oil of upper oil cylinder only has circumferential rotation, Radial Flow from inside to outside, does not collect
Gather inboard thrust bearing and the heat of guide bearing be difficult to the oil cooler heat exchange with outside and take out of, also result in thrust
Bearing and guide bearing temperature is excessively high or even tile kilning.The prior art is mainly the self-circulation cooling system passed through outside setting, is passed through
Pump extracts in-oil cylinder high temperature grease out, re-enters oil cylinder after external cooling system is cooling.This method not only cost
Height, and not can solve the problem of pasta is uneven in oil cylinder, because the oil at thrust bearing and top guide bearing is reduced, friction hair
The problem of heat gathers, and leads to the raising of the temperature of thrust bearing and guide bearing or even tile kilning does not solve still.
