JHMB28 type slow speed winch is a kind of typical mine auxiliary transportation equipment. This type of winch is mainly used in coal mine roadway dust or explosive gas environment of less than 30 DEG in the angle of the traction weight and hydraulic mining working face support withdrawal shift, to use and handling. The design idea is first to determine the diameter of the given data parameters of steel wire rope, various size parameters, then calculating drum roll of wire rope, through the given data motor speed and power, so as to select the motor, determine the transmission ratio, then assigned to each reducer to calculate the various parameters, the calculation and parts check the shaft, shaft coupling, brakes and other institutions. This paper mainly describes the selection process development slow winch and the specific design of the slow winch and ponents, the design of the both sides of the two stage gear are respectively arranged in the electric motor and the drum, pact structure, small size, reduce the use of the base material and the cost is low。 the growth of strip, the base was sledlike, the mobility, smooth operation, safe and reliable, convenient operation. Because the machine is used for mine, so must have proof ability, therefore the selection of explosionproof motor instead of squirrelcage motors original。 winches are mainly driven by gear worm drive system, including the spur gear transmission and the circular worm drive. Finishing grinding wheel worm axial section is a circular arc shape, which can get high accuracy, high carrying capacity, the advantages of high transmission efficiency, are widely used in metallurgy, mine, chemical industry, building, lifting machinery and other equipment. 安徽理工大學(xué) 畢業(yè)設(shè)計(jì) III KEYWARDS ： slow speed winch ， circular worm gear reducer ，explosionproof machine， pact form 安徽理工大學(xué) 畢業(yè)設(shè)計(jì) i 摘要 ......................................................................
