文档介绍：摘要
JT系列提升绞车可供煤矿、金属矿、非金属矿在倾斜巷道作升降物料和人员之用,也可作为小型竖井的提升设备。据制造工艺的不同,可把提升机的滚筒结构分为铸造一焊接混合型(支轮为铸造,滚筒为焊接)和焊接型。
机械传动系统包括减速器和联轴器,矿井提升机主轴的转数由于受提升速度的限制,一般在l0一60转/|分之间,而用作拖动的电动机的转数,一般在480一960转/分之间。这样,除采用低速直流电动机拖动外,一般情况下不能将主轴与电动机直接联接,中间必须经过减速器。因而减速器的作用是减速印传递动力。联轴器由半联轴器、柱销等零件组成。由于柱销具有缓冲和减震作用,因而具有传动平稳、噪音小、安全可靠、易于维护等优点。主轴与减速器输出轴的连接采用齿式联轴器。
润滑系统是一切机械系统中很重要的一个环节。润滑系统的作用是:在提升机工作时,不间断地向主轴承、减边器轴承和啮合齿面压送润滑油,以保证轴承和齿轮能良好的工作润滑系统必须与自动保护系统和主电动机联锁
。提升绞车主轴应能承受工作过程中的外负荷而不发生残余变形和过量的弹性变形,同时要保证一定的使用寿命。主轴往往是提升机中重量最大的一个零件,其尺寸和传递的力矩也较大。

Abstract
JT Series hoist for coal, metal mining, non-metallic mineral movements in the tilt of roadway materials and personnel for use in small shaft can also be used as the upgrading of equipment. According to the different manufacturing process which could take the drum hoist structure casting a hybrid welding (support wheel for the casting, roller for welding) and the welding-type.
Reducer and the mechanical transmission system including the coupling, the main axis of mine hoist to raise the speed of a few because of the restrictions, generally 60 to 1 l0 / | between points, and the motor used to drag a few, generally 480 a 960 r / min between. In this way, in addition to the use of low-speed DC motor drag outside, under normal circumstances can not be directly connected to the motor spindle with the middle through reducer. Reducer thus slow down India's role is to transfer power. Coupling by the semi-coupling and ponent parts inventory. Sales as a result of column buffer and shock-absorbing role, so they have a smooth drive, the noise of small, safe, reliable, easy to maintain and so on. Spindle and the reducer output shaft gear coupling used to connect.
Lubrication of all mechanical systems is a very important aspect. Lubrication system is: in the elevator work, uninterrupted to the main bearings, bearings and browser side by tooth meshing Pressure lubricants, bearings and gears in order to ensure t
