1、JHMBJHMB- -2828 慢速绞车设计慢速绞车设计 DESIGN OF JHMB-28 LOW-SPEED WINCH 摘要 JHMB-28 型慢速绞车是一种典型的矿山辅助搬运设备。该型绞车主要适用于煤矿井 下有煤尘或爆炸性气体环境中在倾角小于 30的巷道牵引重物以及采煤工作面液压支 架的撤移、调向和搬运之用。 本次设计的绞车主要采用齿轮-蜗杆传动系统传动，包括圆柱直齿轮传动和圆弧蜗 轮蜗杆传动。蜗杆用轴向剖面为圆弧形的砂轮进行精加工，可获得较高的精度，具有承 载能力大，传动效率高的优点，被广泛用于冶金、矿山、化工、建筑、起重等机械设备 中。 该绞车结构紧凑，外形尺寸小；结构为近似布置，

2、外形美观，成长条形，底座呈雪 橇状，实现了可移动性，运转平稳，安全可靠，操作方便。 关键词：关键词：慢速绞车，圆弧蜗轮蜗杆，慢速绞车，圆弧蜗轮蜗杆，结构紧凑，结构紧凑，可移动可移动 II DESIGN OF JHMB-28 LOW-SPEED WINCH ABSTRACT JHMB-28 is a type of low-speed winch is a typical auxiliary marchinery of handing device for Mining. This kind of winch mainly being applied in pulling heavy objec

3、ts in the roadway with inclination less than 30and in the cocal mine dust or explosive gas environment. At the same time it can be used for shifting 、adjusting and handing of the support in the cocal face hydraulic. This winch design is mainly taking the cylinder worm gearing and gearing ,including

4、the straight gear transmission and the cylinder worm gearing transmission . The worm is being higher working used the arc-shaped grinding wheel in the axial profile . It has higher accuracy 、a larger carring capacity and high transmission efficiency,which is widely used in metallurgy、mining、 chemica

5、l、construction、cranes and other manchinery. It has compact structuce and smalloutline dimensions to this kind of winch. It has a binary approximate structure and a beautiful and dignified appearance. The product appearance is ski and has movbility. It has the characteristics of light、weight、high efficiency、low enery、run steadily and low noise.
