SLEEVE BEARING TYPE MOTOR OF OIL SHIELD STRUCTURE

摘要

The present invention relates to an oil seal structure of a sleeve bearing type motor. In particular, the shaft bearing structure of the sleeve bearing structure reduces leakage of lubricating oil, thereby extending the life of the motor and preventing noise and fixing the rotor. An oil seal structure of a sleeve bearing type motor that can also be used as a dual-use.;The present invention is characterized in that the oil seal structure of the sleeve bearing type motor in which the shaft of the rotor is supported by the sleeve is provided with oil sealing means for preventing the outflow of oil between the rotor and the shaft.;As described above, in the present invention, when oil flows out of the sleeve according to the rotation of the rotor shaft, a recycle structure is formed by splashing the leaked oil into the sleeve by splashing it from the outer peripheral portion of the oil seal to the inner wall of the bearing housing by centrifugal force. As it reduces the amount of leaked oil, it is possible to extend the life of the motor and reduce the noise.;In addition, the outer periphery of the oil seal made of elastic material can be set to a larger diameter by a predetermined size than the inlet of the bearing housing to prevent detachment of the rotor, which makes it easy to automate the coupling / disengagement of the rotor to the bearing housing. And there is an advantage that can simplify the process.
