Water-cooling cutting motor installed in rocker of low seam mining machine

Abstract

The invention provides a water-cooling cutting motor installed in a rocker of a low seam mining machine. The water-cooling cutting motor installed in the rocker of the low seam mining machine consists of an electromagnetic part and an electromagnetic part protective shell, wherein the electromagnetic part protective shell consists of an inner water jacket and a cooling water channel groove arranged on the inner water jacket; an outer water jacket is not arranged in the electromagnetic part protective shell of the water-cooling cutting motor installed in the rocker of the low seam mining machine and is replaced by a rocker shell of the low seam mining machine, thus the thickness of the outer water jacket is reduced in the water-cooling cutting motor installed in the rocker of the low seam mining machine, the size of the electromagnetic part is correspondingly enlarged under the condition that the size of the cutting motor is limited by the height of a certain coal layer, and the power of the cutting motor is enlarged; or under the condition that the power of the motor is not changed, the size of the cutting motor is correspondingly reduced so as to adapt to exploitation work of a lower coal seam. In addition, because the rocker shell of the low seam mining machine is adopted to replace the outer water jacket, the connection modes of cooling water are diversified and are selectable.

Description

Technical field: [0001] The invention relates to the technical field of motors, in particular to a water-cooled cutting motor installed in a rocker arm of a thin coal seam shearer. Background technique: [0002] In the prior art, cutting motors for thin coal seam shearers are mostly installed in the rocker arm of the shearer, please refer to figure 1 , figure 2 , which are respectively a cross-sectional schematic view and a longitudinal cross-sectional schematic view of an existing cutting motor 10 for a coal shearer. The cutting motor 10 for a coal shearer includes an electromagnetic component 11 and a water-cooling component 12 . The water cooling component 12 includes an inner water jacket 121 , an outer water jacket 122 and a groove 123 arranged on the inner water jacket. The inner water jacket 121 is assembled with the outer water jacket 122 to form a cooling channel. The water-cooling component 12 is wrapped outside the electromagnetic component 11 and plays the "r...

AI Technical Summary

Problems solved by technology

[0003] However, the traditional structure of the water-cooled parts of the cutting motor for the above-mentioned coal mining machine occupies a certain volume of the cutting motor for the coal mining machine, so that when a certain coal seam height limits the size of the cutting motor for the coal mining machine, mining The size of the electromagnetic components of the cutting motor for coal mining machines is also limited, so it is difficult to increase the power of the motor

This cannot meet the small size and high power requirements of the shearer motor used in the thin coal seam mining process
