Abstract
The invention relates to a mining two-stage planetary gear speed reducer for a scraper conveyer in an underground coal mine, and particularly relates to a two-stage planetary gear speed reducer for a scraper conveyer. The two-stage planetary gear speed reducer comprises a box body (1) and a high-speed shaft (2) stretching in the box body (1), and is characterized in that the high-speed shaft (2) is in transmission connection with an output shaft via a high-speed-stage planetary gear train (3) and a low-speed-stage planetary gear train (5) sequentially. The input end and the output end of the high-speed shaft of the speed reducer disclosed by the invention are coaxial; the speed reducer is vertical to the scraper conveyer and installed at the head and the tail of the scraper conveyer respectively; and during use, the speed reducer and a drive part for the speed reducer are arranged in a roadway which is already protected, and the both ends of the scraper conveyer have no need to be protected by a special hydraulic support, so that a protection pressure can be reduced.
Description
Technical field
The present invention relates to be applicable to the mining two-stage epicyclic reduction of colliery underground scraper conveyor, especially a kind of slat conveyer two-stage epicyclic reduction.
Background technology
The working face conveyor retarder is three grades of tapered cylindrical epicyclic reduction gears and three grades of tapered cylindrical gear reducers under the coal mine at present, the input shaft of this retarder and output shaft angle are 90 degree, whole drive division is parallel with slat conveyer after being installed on the slat conveyer, handpiece of scraper conveyer, tail place width are increased, whole drive division place top board need protect with 3 or 4 that lengthen special hydraulic supports, and pressing large driving surface to use for the top has great limitation.
Summary of the invention
The purpose of this invention is to provide a kind of slat conveyer two-stage epicyclic reduction, can be arranged vertically with slat conveyer, and compact conformation, volume are little, adapt under the coal mine top and press working condition.
A kind of slat conveyer two-stage epicyclic reduction comprises casing and stretches into the interior high speed shaft of this casing, and its special feature is: described high speed shaft is successively by level planet circular system, low speed turbine stage planet circular system and output shaft are in transmission connection at a high speed.
Coupler all is installed, the outputting power thereby the pivoted arm of low speed turbine stage planet circular system and output shaft are in transmission connection wherein between high speed shaft and the high speed grade planet circular system, and between high speed level planet circular system and the low speed turbine stage planet circular system.
Cooling mechanism wherein also is installed in casing.
Its high speed level Transmission Ratio of Planetary Gear Trains is 5～8, and the low speed turbine stage Transmission Ratio of Planetary Gear Trains is 4.5～5.5, and the output shaft rotating speed is at 25～40 rev/mins.
High speed shaft input end and the mouth of retarder of the present invention are coaxial, retarder is vertical with slat conveyer, be installed in head, the tail of slat conveyer, retarder and drive division thereof are arranged in by in the protection crossheading well during use, the slat conveyer two ends do not need special hydraulic support protection, can reduce to protect pressure.
