Abstract
The utility model discloses a unilateral type speed reducer for a mine transport winch. The unilateral type speed reducer for the mine transport winch comprises a bevel gear box and a carrier gear box, a longitudinal input shaft is installed on one side of the bevel gear box in rotating mode, a shaft gear is installed at the end of the input shaft and meshed with a bull gear, the bull gear is installed at the front end of a horizontal flat key shaft, a central gear is installed at the rear end of the flat key shaft, a plurality of planetary gears are meshed with the outer portion of the central gear, the planetary gears are respectively and rotatably installed on a rotating disk of a planetary carrier, an annular gear matched with the planetary gears is fixedly arranged on the side wall of the bevel gear box, a pinion is fixedly installed on a rotating shaft of the planetary carrier, and a carrier gear rotatably installed in the carrier gear box is meshed with the outer portion of the pinion. The unilateral type speed reducer for the mine transport winch is high in transmission efficiency, meets requirements for reliability of a large-tonnage soft start system and a brake system, is simple in production process, convenient to operate, safe and reliable, and can achieve winding and unwinding of a rope and braking operation during usage without frequent starting of a motor through positive and negative rotation.
Description
Technical field
The utility model relates to a kind of new type mining Transport Machinery, is specifically related to a kind of mining haulage haulage gear with one-sided formula 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 driving efficiency high, can realize the large-tonnage soft start, be fit to the narrow characteristics such as working space under the coal mine, but need in use rotating frequent starting motor, and exist the problems such as noise is large of using.As: 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 a kind of mining haulage haulage gear with one-sided formula retarder, driving efficiency is high, satisfy the reliability of large-tonnage Soft Starting System and brake system, production technology is simple, easy to operate, safety and reliability, and frequently the rotating actuating motor can be realized withdrawing rope and braking work in use.
The technical solution of the utility model is as follows:
Mining haulage haulage gear is with one-sided formula retarder, include bevel gear housing, gap bridge gear case, bevel gear housing one side is rotatablely equipped with longitudinally input shaft, the end of input shaft is equipped with shaft gear, shaft gear is engaged with big gear wheel, big gear wheel is installed on the front end of horizontal flat key axle, the rear end of flat key axle is equipped with sun gear, the sun gear external toothing has several planetary wheels, planetary wheel rotates respectively on the rotating disk that is installed on pinion carrier, the bevel gear housing sidewall is fixedly installed the internally toothed annulus that is complementary with planetary wheel, is installed with miniature gears in the rotating shaft of pinion carrier, and the miniature gears external toothing has rotates the carrier gear that is installed in the gap bridge gear case.
Be installed with respectively brake wheel in the rotating shaft of described pinion carrier.
Be provided with bracing frame between described internally toothed annulus and the brake wheel.
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.Adopt the full symmetric structure, coordinate control by left and right sides Manual brake and realize reel rotating and braking work, and then avoided the rotating frequent starting of motor.
Driving efficiency of the present utility model 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, speed governing, switch operation more convenient and quicker, 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, mining haulage haulage gear is with one-sided formula retarder, include bevel gear housing 1, gap bridge gear case 2, bevel gear housing 1 one sides are rotatablely equipped with longitudinally input shaft 3, the end of input shaft 3 is equipped with shaft gear 4, shaft gear 4 be engaged with big gear wheel 5, big gear wheel 5 is installed on respectively on the front end of horizontal flat key axle 6, the rear end of flat key axle 6 is equipped with sun gear 7, sun gear 7 external toothings have several planetary wheels 8, planetary wheel 8 rotates and is installed on the rotating disk 9 of pinion carrier, be fixedly installed the internally toothed annulus 10 that is complementary with planetary wheel on the bevel gear housing sidewall, be installed with miniature gears 12 in the rotating shaft 11 of pinion carrier, miniature gears 12 external toothings have rotates the carrier gear 13 that is installed in the gap bridge gear case; Be installed with respectively brake wheel 14 in the rotating shaft of pinion carrier; Be provided with bracing frame 15 between internally toothed annulus and the brake wheel.
