Abstract
The invention relates to a drum shearer, and particularly relates to a novel shearer rocker arm. The novel shearer rocker arm is used for overcoming the defects of the traditional rocker arm structure technology. The novel shearer rocker arm comprises a coal cutting drum, a planetary reducer, a permanent magnet motor, a cooler, and a rocker arm shell, wherein the permanent magnet motor comprises a permanent magnet motor rotor, a permanent magnet motor stator and a bearing; the permanent magnet motor rotor is directly connected with a coal drum through the planetary reducer. Compared with the prior art, the improved rocker arm is driven by a low-speed large-torque permanent magnet motor instead of a high-speed small-torque asynchronous motor; an output shaft of the permanent magnet motor is low in speed, large in torque, and less in mechanical drive with the coal cutting drum.
Description
Technical field
The present invention relates to a kind of drum shearer, be specially a kind of novel rocker arm of coal mining machine.
Background technology
In conventional double drum type coal-winning machine, rocking arm all is the little moment of torsion Asynchronous Motor Driving of employing high speed, and process two-stage spur gear and planetary reduction gear slow down to increase and turn round back drive coal cutting cylinder rotation realization coal cutting function.Coal-winning machine is in the coal cutting process; rocking arm is in a fixing obliquity for a long time; so just have a problem; the gear lubricant of rocking arm inside flows to lowest part; can not circulate well; the gear that is in eminence can not well be lubricated, and rocking arm is in this duty for a long time, can reduce the application life of rocking arm greatly.This situation is to be that high rotating speed, little moment of torsion and coal cutting cylinder need the slow-speed of revolution, high pulling torque by asynchronous motor, mechanical drive train between them is more to be caused, can not obtain fine lubricated this situation so want to change the rocking arm internal gear, then must improve design to the structure of existing rocking arm.
Summary of the invention
The rocker arm of coal mining machine that the present invention provides a kind of low-speed big magneto to drive for the defective that overcomes existing rocker structure technology.
Technical scheme of the present invention is, a kind of novel rocker arm of coal mining machine, comprise coal cutting cylinder, planetary reduction gear, magneto, cooler, rocking arm housing, magneto is made up of permanent magnet machine rotor, permanent magnet motor stator, bearing, and described permanent magnet machine rotor directly connects the coal cylinder by planetary reduction gear.
Compared with prior art, the rocking arm after the present invention improves adopts the low-speed big magneto to replace the little moment of torsion Asynchronous Motor Driving of high speed, and the output shaft speed of magneto is low, moment of torsion is big, and the machine driving between it and the coal cutting cylinder is few.Magneto and planetary reduction gear from very close to and old-fashioned rocking arm reduced the two-stage machine driving than the centre, magneto directly drives planetary reduction gear and drives cylinder and rotate, and reaches the purpose of coal cutting.She Ji rocking arm like this, no matter how rocking arm tilts, all gears of its inside can both obtain continual lubricated.The present invention is directed to lubricated this defective that the rocking arm internal gear can not be good, designed the rocking arm that new-type low-speed big magneto drives, optimize the rocking arm drive mechanism, made that the rocking arm overall structure is compacter, had advantages such as simple in structure, easy to operate, that use is flexible.After above-mentioned improvement, this rocking arm can solve the lubrication problem that rocker arm of coal mining machine exists fully.
