Abstract
The utility model relates to a mine dispatching winch, comprising a flame-proof motor, an eccentric shaft, a balance block, dual articulated gears, a large and a small gear rings, a roller, a braking wheel, an auxiliary support, a sealing device, a contracting brake, a left and a right supporting frames, etc. The flame-proof motor directly transmits dynamic force to the eccentric shaft for driving the dual articulated gears installed on the eccentric axle, and the dual articulated gears are separately meshed with the small gear ring arranged on the roller and the large gear ring arranged on the braking wheel. The contracting brake is utilized to enable the roller to work or stop. The adoption of the transmission form of meshing the dual articulated gears with the two annular gears enables the utility model to have the advantages of compact structure, reasonable structure, light weight and high rigidity, and lubricating conditions are greatly improved because of adopting the sealing device.
Description
The utility model relates to a kind of mine winch, a kind of Winch for mine dispatch of more specifically saying so.
The Winch for mine dispatch of domestic production at present and use mostly is the fifties product greatly, this winch adopts two-stage planet transmission or two-stage inner gear to add the type of drive of primary planet pinion, its Transmission has eight gears and two (or one) pinion carriers, and the employing grease lubrication, thereby exist that transmission link is many, shortcomings such as complex structure, cost height, noise are big, poor lubrication.
A kind of few tooth difference transmission drawing hoist and car hauler are disclosed on the Chinese patent communique, the patent No.: 91226717.8, this winch is under low power situation, and drive disk assembly is difficult to be arranged in the cylinder, and the output gear shaft cantilever support.When cylinder was subjected to diametral load big, the gear mesh operating mode obviously degenerated, and promptly gear is along facewidth direction unbalance stress, thereby influences transmission accuracy.Defectives such as in addition, this winch also adopts grease lubrication, also has poor lubrication, and noise is big.
The purpose of this utility model is to have designed the Winch for mine dispatch that a kind of type of drive is simple, supporting is reasonable, lubricating condition is good in order to overcome above-mentioned the deficiencies in the prior art part.
The purpose of this utility model can realize in the following manner: a kind of Winch for mine dispatch includes flameproof motor, eccentric shaft, balance block, dual gear, large and small internally toothed annulus, cylinder, brake wheel, aiding support, sealing arrangement, band-type brake and left and right bearing support etc.The eccentric shaft input end is provided with endoporus, connect with motor output shaft by linking bond, the other end of eccentric shaft is equipped with dual gear and balance block, balance block is used to eliminate the radial imbalance force of eccentric shaft, dual gear is with big, the small internal gear engagement, greatly, small internal gear is separately fixed on brake wheel and the cylinder, on brake wheel and cylinder, band-type brake is housed, aiding support supports cylinder and brake wheel each other, its support stiffness is greatly improved, sealing arrangement is sealed in the epitrochoidal chamber of Transmission lubricating fluid reliably, realizes the good lubrication of Transmission and bearing, and whole winch is by a left side, right branching bolster supporting is on base.During work, the power of electrical motor passes to eccentric shaft by linking bond, makes its rotation, and eccentric shaft drives dual gear again and rotates, when the brake wheel glancing impact, bull gear maintains static, little gear ring output, and drive cylinder work, when drum braking, little gear ring maintains static, and bull gear output drives brake wheel idle running.
The utility model compared with prior art has following advantage:
(1) the utility model adopts the key connecting mode directly the power of motor to be passed to eccentric shaft, and replace eight gears and two (or one) pinion carriers of existing car haulers with a dual gear and two internally toothed annuluss, the Transmission of car hauler is significantly reduced, thus have compact conformation, rationally distributed, in light weight, cost is low, the efficient advantages of higher.
(2) cylinder leans on a side of brake wheel to increase an aiding support again at cylinder except that being bearing on the left and right bearing support by two supplementary bearings in it, and cylinder and brake wheel are supported each other, and therefore, support effects is good, the support stiffness height.
(3) the utility model has been owing to adopted the failure-free sealing arrangement, thereby can use hydraulic oil lubricated, thereby the lubricating condition of Transmission is greatly improved, and noise reduces greatly.
Description of drawings:
Accompanying drawing is a structural front view of the present utility model.
The utility model is described in further detail with reference to the accompanying drawings:
Shown in accompanying drawing: a kind of Winch for mine dispatch, include flameproof motor 1, it is fixed on the base 14 by left bearing support 2, one end of eccentric shaft 4 is inserted on the output shaft of flameproof motor 1, the aperture, left side of cylinder 3 is mounted with contiguous block 15, the aperture, right side is mounted with little gear ring 6, match with bearing and sealing arrangement 16 on being placed in eccentric shaft 4 in the left side of cylinder 3, also be mounted with bearing between little gear ring 6 left sides and the eccentric shaft 4, be mounted with dual gear 5 by bearing on the eccentric segment of eccentric shaft 4, the miniature gears of dual gear 5 is meshed with little gear ring, the both sides of brake wheel 10 are placed on cylinder 3 and the eccentric shaft 4 by aiding support 8 and bearing respectively, aiding support 8 supports cylinder 3 and brake wheel 10 each other, rigidity greatly improves, between brake wheel 10 and the cylinder 3 sealing arrangement 17 is arranged, in the brake wheel 10 inboard corresponding positions of big gear wheel bull gear 7 is arranged with dual gear 5, bull gear 7 is meshed with the big gear wheel of dual gear 5, be mounted with band-type brake 11 on the brake wheel 10, also be mounted with band-type brake 11 on the cylinder 3, right bearing support 12 is fixed on the base 14, between itself and brake wheel 10 right sides bearing is arranged, thereby eccentric shaft 4 is supported together with the part on it, between right bearing support 12 and brake 10, sealing arrangement 9 is arranged, on eccentric shaft 4, also be mounted with balance block 13, to eliminate the radial imbalance force of eccentric shaft 4.
Working process: the power of electrical motor 1 passes to eccentric shaft 4 by key, thereby the dual gear 5 on the eccentric shaft 4 is rotated, and meshes with two internally toothed annuluss, and when brake wheel 10 glancing impacts, bull gear 7 maintains static, and little gear ring 6 drives the cylinder work; When drum braking, little gear ring 6 maintains static, and bull gear 7 rotates, brake wheel 10 idle running, and sealing arrangement 9,16,17 is sealed in the epitrochoidal chamber of Transmission lubricating fluid reliably, realizes the good lubrication of Transmission.
