Abstract
The utility model discloses a reducer for a haulage transport winch for a mine. The reducer for the haulage transport winch for the mine comprises a bevel gear box and a carrier gear box, a longitudinal input shaft is arranged on one side of the bevel gear box, and a shaft gear is arranged on the input shaft. A horizontal flat key shaft is arranged in the bevel gear box in a rotating mode, a large bevel gear which is matched with the shaft gear is arranged at the front end of the flat key shaft, a center gear is arranged at the rear end of the flat key shaft, a plurality of planetary gears are meshed outside the centre gear, the planetary gears are respectively fixed on a turnplate of a planetary support outside the flat key shaft, a small gear which is arranged in the carrier gear box is fixedly arranged on the rotary shaft of the planetary support, and the carrier gear which is arranged in the carrier gear box in a rotating mode is meshed outside the small gear. The reducer for the haulage transport winch for the mine is simple in assembly technology, convenient to operate, and safe and reliable.
Description
Technical field
The utility model relates to a kind of mining transportation machinery, is specifically related to a kind of mining haulage haulage gear retarder.
Background technology
Patent No. CN03132226.3 discloses a kind of technical scheme of haulage haulage gear, this scheme adopts finishing bevel gear cuter and Planetary Gear Transmission, has the driving efficiency height, can realize the large-tonnage soft start, be fit to the narrow characteristics such as working space under the coal mine, but still exist complex structure, assembling difficulty and use the problems such as noise is large.Adopt strap of the brake braking inner gear outer ring to realize transmission, the strap of the brake one end and base are fixed, the other end connects the rim brake connecting rod, when actuating force passes to strap of the brake end by 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 large diametral load in the inner gear outer ring, causing in the transmission process that vibration is violent, noise is large, frictional heating is more serious etc., bringing certain potential safety hazard.
The utility model content
The purpose of this utility model provides that a kind of assembly technology is simple, easy to operate, the mining haulage haulage gear retarder of safety and reliability.
The technical solution of the utility model is as follows:
A kind of mining haulage haulage gear retarder, include bevel gear housing, gap bridge gear case, bevel gear housing one side is equipped with longitudinally input shaft, 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, the rear end of flat key axle is equipped with sun gear, 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 installed on respectively on the rotating disk of the planet stent outside the flat key axle, be installed with the miniature gears that is positioned at gap bridge gear case in the rotating shaft of planet stent, the miniature gears external toothing has rotates the carrier gear that is installed in the gap bridge 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 bevel gear wheel outside.
The utility model adopts Planetary Gear Transmission: when Manual brake mediates, neither brake inner gear ring, also do not brake brake wheel, be differential gear train this moment; When Manual brake pushed away forward, pinion carrier was braked, and inner gear ring rotates, and when the past post-tensioning of Manual brake, 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 by Manual brake, and back and forth conversion between differential gear train and two kinds of planet circular systems realizes the large-tonnage soft start.
The utility model driving efficiency is high, can realize the large-tonnage soft start, be fit to the narrow characteristics such as working space under the coal mine, technique simply is convenient to assembling and maintenance, the speed governing more convenient operation is quick, braking effect is better, the raising that all improves to some extent of the aspects such as life-span, tractive force, work efficiency, safety and reliability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of mining haulage haulage gear retarder, include bevel gear housing 1, gap bridge gear case 2, bevel gear housing 1 one sides are equipped with longitudinally input shaft 3, shaft gear 4 is installed on the input shaft 3, be 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, the end of bevel gear wheel 6 is with the internally toothed annulus 9 that is complementary with planetary wheel 8, planetary wheel 8 is fixedly installed on 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 gap bridge 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 gap bridge gear case, be installed with inside brake wheel 14 in the rotating shaft of planet stent, the outer end of flat key axle is equipped with the outer brake wheel 15 that is positioned at bevel gear wheel 6 outsides.
