Abstract
The invention discloses a speed reducer for carrying a transportation winch for a mine. The speed reducer comprises a bevel gear box and a bridge gear box, wherein one side of the bevel gear box is provided with a vertical input shaft, a shaft gear is arranged on the input shaft, a transverse flat key shaft is rotatablely arranged in the bevel gear box, the front end of the flat key shaft is provided with a large bevel gear engaged with the shaft gear, the back end of the flat key shaft is provided with a center gear, the outer side of the center gear is engaged with a plurality of planetary gears, the planetary gears are respectively and fixedly arranged on a turntable of a planetary support frame arranged at the outer side of the flat key shaft, a small gear positioned in the bridge gear box is fixedly arranged on the rotating shaft of the planetary support frame, and a bridge gear rotatablely arranged in the bridge gear box is engaged outside the small gear. The speed reducer has the advantages that the assembly process is simple, the operation is convenient, and the carrying transportation winch for the mine can be safer and more reliable.
Description
Technical field
The present invention relates to a kind of mining Transport Machinery, be specifically related to a kind of haulage haulage gear of mining planet soft start.
Background technology
Patent No. CN03132226.3 discloses a kind of technical scheme of haulage haulage gear; This scheme adopts finishing bevel gear cuter and epicyclic gear transmission; Has the driving efficiency height; Can realize the large-tonnage soft start, be fit under the coal mine characteristics such as narrow working space, but still exist complex structure, assembling difficulty and use problems such as noise is big.As: two overlap bull gears, protective cover, carrier gear and miniature gears etc., have increased the complexity and the assembly difficulty of structure, have increased winch single-piece width and manufacturing cost simultaneously; Adopt strap of the brake braking inner gear outer ring to realize transmission; The strap of the brake one end and base are fixed, and other end connection hand brake connection rod is when actuating force passes to strap of the brake end through the connecting rod amplification; This power is further amplified by the strap of the brake again and is acted on the inner gear outer ring; Act on very big diametral load on the large internal gear outer ring, causing in the transmission process that vibration is violent, noise is big, frictional heating is more serious etc., bringing certain potential safety hazard.
Summary of the invention
The purpose of this invention is to provide a kind of mining haulage haulage gear and use retarder, assembly technology is simple, easy to operate, the mining haulage haulage gear of safety and reliability.
Technical scheme of the present invention is following:
A kind of mining haulage haulage gear is used retarder; Include bevel gear housing, carrier gear case, bevel gear housing one side is equipped with input shaft longitudinally, and shaft gear is installed on the input shaft; Be rotatablely equipped with horizontal flat key axle in the bevel gear housing; The front end of flat key axle is equipped with the bevel gear wheel that is meshed with shaft gear, and the rear end of flat key axle is equipped with sun gear, and the sun gear outside is engaged with several planetary wheels; The bevel gear housing outside is fixedly connected with the internally toothed annulus that is complementary with planetary wheel; Planetary wheel is fixedly set in respectively on the rotating disk of the planet stent outside the flat key axle, is installed with the miniature gears that is positioned at the carrier gear case in the rotating shaft of planet stent, and the miniature gears external toothing has rotates the carrier gear that is installed in the carrier gear case.
Be installed with the inside brake wheel in the rotating shaft of described planet stent.
The outer end of described flat key axle is equipped with the outer brake wheel that is positioned at the finishing bevel gear cuter outside.
The present invention adopts epicyclic gear transmission: when the hand brake lock mediates, neither brake inner gear ring, also do not brake brake wheel, be differential gear train this moment; When the hand brake lock pushed away forward, pinion carrier was braked, and inner gear ring rotates, and when hand brake lock during toward post-tensioning, inner gear ring is braked, and pinion carrier is rotated, and both of these case is planet circular system.This haulage haulage gear is exactly the control through the hand brake lock, and transition back and forth between differential gear train and two kinds of planet circular systems realizes the large-tonnage soft start.
Driving efficiency of the present invention is high, can realize the large-tonnage soft start, is fit under the coal mine characteristics such as narrow working space; Technology simply is convenient to assembling and maintenance, and the speed governing more convenient operation is quick, and braking effect is better; The raising that all improves to some extent of aspects such as life-span, tractive force, work efficiency, safety and reliability.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Referring to accompanying drawing, a kind of mining haulage haulage gear is used retarder, includes bevel gear housing 1, carrier gear case 2; Bevel gear housing 1 one sides are equipped with input shaft 3 longitudinally; Shaft gear 4 is installed on the input shaft 3, is rotatablely equipped with horizontal flat key axle 5 in the bevel gear housing 1, the front end of flat key axle 5 is equipped with the bevel gear wheel 6 that is meshed with shaft gear 4; The rear end of flat key axle 5 is equipped with sun gear 7; Sun gear 7 outsides are engaged with several planetary wheels 8, and the end of bevel gear wheel 6 has the internally toothed annulus 9 that is complementary with planetary wheel 8, and planetary wheel 8 is fixedly set in respectively on the rotating disk of planet stent 10 in flat key axle 5 outsides; Be installed with the miniature gears 12 that is positioned at carrier gear case 2 in the rotating shaft 11 of planet stent 10; Miniature gears 12 external toothings have rotates the carrier gear 13 that is installed in the carrier gear case, is installed with inside brake wheel 14 in the rotating shaft of planet stent, and the outer end of flat key axle is equipped with the outer brake wheel 15 that is positioned at the finishing bevel gear cuter outside.
Claims (3)
