Abstract
The invention discloses an idler-free transmission device for a slicing portion of drum shearer. The mechanical transmission system of the slicing portion of a traditional drum shearer adopts a planetary gear train and an ordinary gear train to realize the required ratio transmission and adopts an idler wheel to satisfy the requirement of the centre distance, which causes the working temperature of the slicing portion is high. The idler-free transmission device for the slicing portion of the drum shear comprises a casing (6), a drive motor (1) mounted in the casing (1) moves forwards to the coaxial part of the spiral drum, and the drive motor is connected with the planetary gear train (4). The invention is used together with the drum shearer.
Description
Technical field:
The present invention relates to a kind of coal mine machinery equipment technology, particularly a kind of slicing portion of drum shearer does not have the idle pulley drive mechanism.
Background technology:
At present, drum shearer extensively adopts many motors transversal arrangement, each cutting units adopts independently Motor Drive, traditional cutting units drive motors and operating mechanism's helix drum respectively are provided with its two ends, and axis is parallel to each other, be depicted as traditional cutting units typical structure as accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, form by drive motors 1, fixed shaft gear train 2 (1～3 grade of transmission is generally arranged), idle pulley 3 (2～3 grades of transmissions are generally arranged), planet circular system 4 (1～2 grade of transmission is arranged), helix drum 5 (coal cutting mechanism) and cutting units casing 6 etc. usually.Its operating principle be by the fixed shaft gear train deceleration transmission and through idle pulley apart from transmission, drive the helix drum rotation through the planet circular system deceleration transmission again, realize coal cutting.
In order to be suitable for different working seam thickness, cutting units will have certain length, and requires to swing up and down the height of adjustable screw cylinder around the back interface point.The machine driven system of cutting units adopts planet circular system and fixed shaft gear train to realize the speed ratio transmission that requires, adopt the idle pulley transmission to satisfy the requirement of center to center distance, the general employing of cutting units 3～5 gear-stage velocity ratio transmissions, speed ratio is between 15～75, mechanically operated gross efficiency about 0.8, along with driving power constantly increases, present single drive motors power has reached 800～1000kW, its power loss reaches about 160～200kW, the power major part of loss is converted into heat, cause the operating temperature of cutting units very high, usually will adopt the passive mode radiating and cooling of water-cooled, comparatively temperature also can only be controlled at about 90 °, therefore under the ideal situation, simplify drive mechanism, improve machinery driving efficiency and seem particularly important.
Summary of the invention:
The objective of the invention is provides a kind of idler-free transmission device for slicing portion of drum shearer based on above-mentioned situation.This slicing portion of drum shearer does not have the simple in structure of the idle pulley kind of drive, and the transmission efficiency height is beneficial to the control of temperature rise simultaneously, improves the reliability of work.
Above-mentioned purpose realizes by following technical scheme:
Idler-free transmission device for slicing portion of drum shearer, its composition comprises: housing, the drive motors that is installed in the described housing moves forward to the coaxial place of helix drum, and described drive motors connects planet circular system.
Described idler-free transmission device for slicing portion of drum shearer, described drive motors reach position is that described planet circular system connects fixed shaft gear train to the cutting units middle part, described planet circular system connects the helix drum that places described housing outer.
Described idler-free transmission device for slicing portion of drum shearer, described planet circular system are the multistage planet train.
Beneficial effect of the present invention:
Idle pulley or the minimizing transmission progression means of the present invention by eliminating non-speed ratio transmission, in the middle of having cancelled the idle pulley transmission, the drive motors reach is arranged, realize the simplification of drive mechanism, and guarantee the needed length that swings up and down of cutting units, the simplification of cutting units machine driven system and the raising of machinery driving efficiency are not only energy-conservation, are beneficial to the control of temperature rise simultaneously, improve the reliability of work.
The simplification of cutting units machine driven system and the raising of machinery driving efficiency are not only energy-conservation, are beneficial to the control of temperature rise simultaneously, improve the reliability of work.The effective way that improves machinery driving efficiency has two aspects, and the one, the manufacturing installation accuracy quality of raising machine driving such as component such as gear, bearing; The 2nd, optimize and simplify drive system structure, determine that rationally transmission progression and gearratio thereof distribute, and eliminate the gear drive (as the idle pulley transmission) of non-several ratios.This patent realizes by optimization and simplified structure scheme that exactly this patent main points are by the idle pulley of eliminating non-speed ratio transmission or reduce transmission progression means, adopts the mode of drive motors reach, and guarantees the needed length that swings up and down of cutting units,
