Disclosed 201310250819.9 " a kind of Novel shearer rocker arm " and notification number are：" roller disclosed in the B of CN 102877841
The structural arrangement form that formula rocker arm of coal mining machine " is used all is that motor is positioned over into rocking arm end, is close to planetary gear speed-reduction
Machine, thus cause its structure so that rocking arm longitudinal length lengthen, to whole coal-winning machine, drag conveyor, hydraulic support sky
Between arrangement produce influence, and rocking arm center of gravity, close to Rocker drum end, complete machine stability is low.
The content of the invention
Technical problem：The invention aims to overcome weak point of the prior art, there is provided a kind of tooth form Chain conveyer
Rocker arm of coal mining machine device, using low-speed big magneto as motor, using silent chain transmission system as primary drive
Chain, the kind of drive is when shearer ranging arm is deformed, you can realize the Flexible Transmission of rocker arm of coal mining machine, and operating mode applicability is good.
Technical scheme：The tooth form Chain conveyer rocker arm of coal mining machine device of the present invention, including roller, rocking arm output shaft, rocking arm are defeated
Permanent magnetism is provided with shaft positioning end cap, rocking arm input shaft, rocking arm input shaft positioning end cap and shearer ranging arm, described shearer ranging arm
Motor, planet-gear speed reducer and silent chain transmission system, described magneto output shaft and planet-gear speed reducer are too
Sun wheel is engaged, and magneto and planet-gear speed reducer composition integrated motor reductor, integrated motor reductor are located at
Shearer ranging arm power intake is intraoral, is connected at a right angle with the silent chain transmission system in the middle part of shearer ranging arm, magneto
The moment of torsion of generation is exported by silent chain transmission system；The planet-gear speed reducer tie-rod output shaft and rocking arm input shaft phase
Even, rocking arm input shaft is connected with silent chain transmission system, and silent chain transmission system is connected with installing the rocking arm output shaft of roller.
Described silent chain transmission system includes input drive sprocket, silent chain, output driven sprocket；Described silent chain
Respectively with input drive sprocket, output driven sprocket engaged transmission, input drive sprocket be fixed on rocking arm input shaft, output from
Movable sprocket is fixed on rocking arm output shaft.
Between the magneto output shaft and planet-gear speed reducer sun gear, planet-gear speed reducer tie-rod output shaft
Between rocking arm input shaft, between rocking arm input shaft and silent chain transmission system, silent chain transmission system and rocking arm output shaft it
Between pass through spline connection transmission.
Beneficial effect：By adopting the above-described technical solution, the present invention solve existing double-ended shearer rocking arm because
Using the small moment of torsion Induction Motor-Driven of high speed, the driving cog that travelling gear system driving-chain is longer, shearer ranging arm deformation is caused
The problems such as train fault rate height, low reliability, noise high energy consumption.Motor, tooth are used as using low-speed big magneto
Shape chain drive system is main driving-chain, and the Flexible Transmission of rocker arm of coal mining machine can be achieved when shearer ranging arm is deformed in the kind of drive,
Operating mode applicability is good.The magneto output torque of use slows down to increase through planet-gear speed reducer and silent chain transmission system to be turned round
Square, is transferred to rocking arm output shaft, rocking arm output shaft is real through roller connection end cap connection roller by output driven sprocket by high pulling torque
The driving of existing roller.Silent chain transmission system uses a pair of principal and subordinate's movable sprockets and silent chain, and then realizes the soft of rocker arm of coal mining machine
Property transmission, solve existing rocker arm of coal mining machine shearer ranging arm deform caused by transfer gear train fault rate it is high the problem of.
Its compact conformation, easy to operate, using effect is good, in the art with wide applicability.
