摘要

JT系列提升絞車(chē)可供煤礦、金屬礦、非金屬礦在傾斜巷道作升降物料和人員之用，也可作為小型豎井的提升設(shè)備。據(jù)制造工藝的不同，可把提升機(jī)的滾筒結(jié)構(gòu)分為鑄造一焊接混合型(支輪為鑄造，滾筒為焊接)和焊接型。

機(jī)械傳動(dòng)系統(tǒng)包括減速器和聯(lián)軸器,礦井提升機(jī)主軸的轉(zhuǎn)數(shù)由于受提升速度的限制，一般在l0一60轉(zhuǎn)／|分之間，而用作拖動(dòng)的電動(dòng)機(jī)的轉(zhuǎn)數(shù)，一般在480一960轉(zhuǎn)／分之間。這樣，除采用低速直流電動(dòng)機(jī)拖動(dòng)外，一般情況下不能將主軸與電動(dòng)機(jī)直接聯(lián)接，中間必須經(jīng)過(guò)減速器。因而減速器的作用是減速印傳遞動(dòng)力。聯(lián)軸器由半聯(lián)軸器、柱銷(xiāo)等零件組成。由于柱銷(xiāo)具有緩沖和減震作用，因而具有傳動(dòng)平穩(wěn)、噪音小、安全可靠、易于維護(hù)等優(yōu)點(diǎn)。主軸與減速器輸出軸的連接采用齒式聯(lián)軸器。

潤(rùn)滑系統(tǒng)是一切機(jī)械系統(tǒng)中很重要的一個(gè)環(huán)節(jié)。潤(rùn)滑系統(tǒng)的作用是：在提升機(jī)工作時(shí)，不間斷地向主軸承、減邊器軸承和嚙合齒面壓送潤(rùn)滑油，以保證軸承和齒輪能良好的工作潤(rùn)滑系統(tǒng)必須與自動(dòng)保護(hù)系統(tǒng)和主電動(dòng)機(jī)聯(lián)鎖

電動(dòng)機(jī)通過(guò)主軸驅(qū)動(dòng)滾筒．主軸也是傳動(dòng)的主要部件。提升絞車(chē)主軸應(yīng)能承受工作過(guò)程中的外負(fù)荷而不發(fā)生殘余變形和過(guò)量的彈性變形，同時(shí)要保證一定的使用壽命。主軸往往是提升機(jī)中重量最大的一個(gè)零件，其尺寸和傳遞的力矩也較大。

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 column component 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 the work can be a good lubrication system with automatic protection systems and the main electrical interlock

Drum through the spindle drive motor. Spindle drive is also the main components. Spindle hoist should be able to work outside the course of the load without the occurrence of excessive residual deformation and elastic deformation, at the same time to ensure that a certain life. Spindle is often the weight of hoisting machine in one of the biggest parts of their size and the torque delivery as well.
