提升机是矿井生产中重要和关键设备之一,主要担负着提升煤炭、矿石和升降人员以及下放物料、工具和设备的主要任务。它是联系地表生产和井下生产的主要运输工具。而作为提升机的关键承载件主轴的完好性一直受到人们的关注,与之相连接的齿轮联轴器是主轴和减速器传递动力的纽带,主轴与减速器一般有两种联接方式:切向键联接和无键过盈联接。中信重工生产的2JK-5 × 2.3/11.5矿井提升机和
Lifts are one of the most important and critical equipment in mine production and are mainly responsible for upgrading coal, ore and lifting personnel as well as decentralizing materials, tools and equipment. It is the main means of transport that connects surface production to downhole production. However, the integrity of the spindle as the key carrier of the hoist has always been the focus of attention. The gear coupling connected with it is a link between the spindle and the reducer to transmit power. The spindle and the reducer generally have two coupling modes: tangential Keyed and keyless fit.
