Electromotor of wood splitting machine

Abstract

The invention discloses an electromotor of a wood splitting machine. The electromotor comprises a front cover, a rotor, a stator, a back cover and a pipe control sleeve, wherein the front cover is provided with a first oil hole and a second oil hole; and the pipe control sleeve passes through the front cover, the rotor and the back cover in sequence. The pipe control sleeve comprises a front part, a middle part and a rear part, wherein the diameter of the middle part is greater than those of the front part and the rear part respectively; a front positioning shoulder and a rear positioning shoulder are arranged in the positions of the middle part adjacent to the front part and the rear part respectively; and oil seals are arranged between the front cover and the front positioning shoulder. According to the invention, the pipe control sleeve is used and the oil holes are formed in the front cover to replace bearings, so that lubricating oils can flow into the pipe control sleeve through the oil holes, thereby reducing frictions; the oil seals are arranged to prevent oils at the oil holes leaking into the electromotor; particularly, a double oil seal structure can achieve preferable seal, thereby decreasing oil leakage possibilities; and the front cover is used as a part of a gear case, and the front cover and an oil tank are formed integrally, thereby reducing the cost. The electromotor provided by the invention has the advantages of small volume, smooth operation, simplicity in maintenance and repair and the like.

Description

technical field [0001] The invention relates to a motor, in particular to a log splitter motor. Background technique [0002] Currently, log splitters are all powered by electric motors. Existing motors for wood splitters need to be combined with gear pumps, not only need to install an oil tank at the front of the motor, but also ensure the tightness of the oil tank, so the volume of the motor after the oil tank is installed is too large, and it is not suitable for small wood splitters Proportion, and the cost is too high, and the tightness cannot be guaranteed, often causing oil leakage. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a wood splitter motor with small volume and good sealing effect. [0004] Technical solution: In order to achieve the above object, a log splitter motor of the present invention includes a front cover, a rotor, a stator, a rear cover and a c...
