Abstract

A floating and communication type scraper winch solves the problem in the prior art that the axial mounting size of a sun gear at the auxiliary reel end is hard to control, the structure sealing is not favorable, oil leakage occurs frequently and the noise in the process of high speed operation is over high. In the scraper winch, a motor, a main reel, an auxiliary reel, a main star wheel train and an auxiliary star wheel train are arranged on a frame; a high speed transmission device is mounted between the main reel and the motor; a floating communication shaft penetrates the main reel and the auxiliary reel and is connected with the main star wheel train, the auxiliary star wheel train and the high speed transmission device; and a left end lid with a bearing support is mounted at the left end of the frame. The scraper winch is characterized in that the high speed transmission device is a two-stage skew gear transmission mechanism, the left end cover has a sealing structure, and a floating bearing mechanism is mounted on the bearing support of the left end lid. The scraper winch has the advantages that the axial mounting size of the sun gear at the auxiliary reel is easy to control; the oil leakage problem is solved; the operation reliability and the service life of the winch are improved; the noise in the process of high speed operation is reduced, and the structural strength of the high speed transmission device is enhanced.

Description

Floating general formula Rabble mine winch

Technical field

The utility model belongs to a kind of winch, and particularly a kind of conveyer between propulsion source and reel that is used for metallic ore and colliery is the gear-driven floating general formula Rabble mine winch of galaxy.

Background technology

There is Jinzhou Mine Machinery Factory to be called the utility model patent of " Rabble mine winch " for " 88216710 ", name in the application number of application on July 28th, 1988 in the prior art.Its transfer device between propulsion source and reel is an epicyclic gear transmission, specifically form by high speed driving unit, main drum, loose drum, operating control and electrical motor, be characterised in that the epicyclic gear transmission that on high speed driving unit, has adopted pinion carrier to float, on operating control, adopted rear pull type can be spacing actuating linkage mechanism, at the bearing place and the main shaft right-hand member of high speed running part seal ring and seal cover cap have been installed respectively; Advantage is that the high speed driven load is evenly distributed, turns round steadily, low, the good seal performance of noise, and operating control becomes instantaneous reinforcing by lasting reinforcing, has alleviated miner's labour intensity greatly.

But, by practical application for many years, reflect that there are some technical matterss in said structure, mainly show driving device, main drum, loose drum and the accumulated error of galaxy gear mechanism on frame, make the sun wheel shaft of loose drum end galaxy gear mechanism be difficult to control to installation dimension, often make between the left end cap of sun wheel and left end the gap too small, causing being in operation is easy to generate collision and friction, and the serviceability and the safety of winch reduce greatly.In addition, a through hole to be arranged in the middle of the left end cap on original device, to also have a bonnet on the left end cap in order sealing, because sealing structure is bad, often leakage of oil reduces the bearing lubrication effect, causes bearing failure; In the floating star wheel mechanism that the right-hand member of former winch motor is installed, noise is excessive in high-speed cruising, and plunging joint damages easily.

Summary of the invention

The purpose of this utility model is in order to overcome the above-mentioned technical matters of mentioning, left end cap structure and right-hand member high speed floating star wheel mechanism are improved, a kind of floating general formula Rabble mine winch that makes the sun wheel shaft of loose drum end to easy control of installation dimension and solution structure leakage of oil problem is provided.

The utility model has a frame and unsteady axis, motor, main drum, loose drum and primary train, secondary star wheel series are installed on frame, between main drum and motor, high speed driving unit is installed, unsteady axis passes main drum, loose drum is connected with high speed driving unit with primary train, secondary star wheel series, left end in frame is equipped with the left end cap that has bearing seat, its special character is: described high speed driving unit is the two-stage spiral gear drive mechanism, and described left end cap is enclosed construction and floating support mechanism is installed on the bearing seat of left end cap.

Above-mentioned floating general formula Rabble mine winch is provided with axial hole on left end cap bearing seat end face, described floating support mechanism is made of the ball, bumping post and the spring that are arranged in the axial hole.

Above-mentioned floating general formula Rabble mine winch, described two-stage spiral gear drive mechanism is made up of intermeshing motor wheel and big gear wheel and intermeshing shaft gear and bevel gear, wherein big gear wheel is connected by key with shaft gear, and bevel gear is connected by spline with unsteady axis.

Advantage of the present utility model is, by increase floating support mechanism on left end cap, has improved assembly technology, and the sun wheel shaft in the secondary star wheel series is controlled easily to installation dimension; Remove left end cap intermediate throughholes and bonnet, solved structure leakage of oil problem, improved winch reliability of operation and service life; Changing the floating star wheel mechanism that right-hand member is installed on original device simultaneously is the transmission of two-stage helical wheel, has reduced the noise in high-speed cruising, has improved the structural strength of high speed driving unit.
