Abstract
The invention discloses a unilateral speed reducer for a mining conveying and transporting winch. The unilateral speed reducer comprises a bevel gear box and a carrier gear box, wherein a lengthways input shaft is rotationally arranged at one side of the bevel gear box; shaft gears which are engaged with a big gear are arranged at the end parts of the input shaft; the big gear is arranged at the front end of the transverse flat key shaft; a sun gear is arranged at the rear end of the flat key shaft; multiple planetary gears which are respectively rotationally arranged on a turntable of a planetary frame are engaged outside the sun gear; inner gear rings matching with the planetary gears are respectively fixedly arranged on the sidewall of the bevel gear box; a pinion is fixedly arranged on a rotating shaft of the planetary frame; and a carrier gear rotationally arranged in the carrier gear box is engaged outside the pinion. The unilateral speed reducer for the mining conveying and transporting winch, disclosed by the invention, has the advantages of high transmission efficiency, satisfaction with reliability of large-tonnage soft start systems and brake systems, simple production technology, operation convenience, and better safety as well as reliability; and rope rewinding and releasing operations and braking operation can be realized without starting up the electric motor by turning positively and negatively frequently when the symmetric conveying and transporting winch for mine is in use.
Description
Technical field
The present invention relates to a kind of new type mining Transport Machinery, be 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 epicyclic gear transmission; Have the driving efficiency height, can realize the large-tonnage soft start, be fit under the coal mine characteristics such as narrow working space; But need rotating frequent starting motor in use, and exist the problems such as noise is big 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, 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 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 folding and unfolding rope and braking work in use.
Technical scheme of the present invention is following:
Mining haulage haulage gear includes bevel gear housing, carrier gear case with one-sided formula retarder, and bevel gear housing one side is rotatablely equipped with input shaft longitudinally; The end of input shaft is equipped with shaft gear, and shaft gear is engaged with big gear wheel, and 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, and planetary wheel rotates respectively on the rotating disk that is installed on pinion carrier, and the bevel gear housing sidewall is set with the internally toothed annulus that is complementary with planetary wheel; Be installed with miniature gears in the rotating shaft of pinion carrier, the miniature gears external toothing has rotates the carrier gear that is installed in the carrier gear case.
Be installed with brake wheel in the rotating shaft of said pinion carrier respectively.
Be provided with bracing frame between described internally toothed annulus and the brake wheel.
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.Adopt complete symmetrical structure, through about manually the damper brake co-operative control realize reel rotating and braking work, and then avoided the rotating frequent starting of motor.
Driving efficiency of the present invention is high; Can realize the large-tonnage soft start, be fit under the coal mine characteristics such as narrow working space, technology 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 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, mining haulage haulage gear includes bevel gear housing 1, carrier gear case 2 with one-sided formula retarder; Bevel gear housing 1 one sides are rotatablely equipped with input shaft 3 longitudinally; 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, and planetary wheel 8 rotates and is installed on the rotating disk 9 of pinion carrier, is set with 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 carrier gear case; Be installed with brake wheel 14 in the rotating shaft of pinion carrier respectively; Be provided with bracing frame 15 between internally toothed annulus and the brake wheel.
