一.滚动轴承装置的概述
我公司高压电机所选用的滚动轴承均为高品质的轴承产品.滚动轴承的机械设计寿命均经过严格的核算,满足用户的使用要求,同时核算了滚动轴承的最小负荷,保证轴承工作在最佳工作状态.轴承装置带不停机注排脂（油）结构, 可在不停机情况下加注或排出润滑脂（油）.
我公司常用的滚动轴承的主要类型及配置见表1:

1. Descriptions of Rolling Element Bearing Device
High quality rolling element bearings are adopted for the high voltage motors. Bearing life and minimum load are calculated to meet the customer’s demand and ensure the best operation conditions of bearings. Such bearings are equipped the regreasing attachment to add or drain out the grease (oil) without stop.
The main adopted bearing types are shown in Table.

Bearing devices are illustrated by attached figures. Please contact the manufacturer if the bearing device is other than the illustrations.
嘿哥们儿 二.滚动轴承的工作温度younha彗星
通常,轴承的温度随着运转的开始慢慢上升,1～2小时后达到稳定的工作状态.如果润滑、安装不合适,则轴承温度会急骤上升,出现异常高温,这时必须停止运转,采取必要的防范措施.滚动轴承的工作温度不得超过95℃，报警温度为90℃,停机温度为95℃. 据用户的需求, 每个轴承可设测温元件（Pt100），将其引线引入测温接线盒内,提供远传温度信号或进行温度显示.轴承测温点的位置距离轴承外圈不超过10mm.
刘亦菲童年照2. Working Temperature of Rolling Element Bearing
Generally the bearing temperature rises gradually and shall be stabilized in 1 or 2 hours. The bearing temperature will increase rapidly if the grease (oil) or assembly does not match the bearing. If so the motor shall be stopped immediately to take necessary actions.
The working temperature for rolling element bearing is 95℃. Upon request Pt100s are equipped as monitoring detectors for bearing temperature. The detectors will alarm if the bearing temperature reaches 90℃ and the motor will stop if the bearing temperature reaches 95℃..
The lead wires of detectors are brought out to the auxiliary terminal box for remote control or signal indication. The bearing temperature measuring points shall not exceed 10mm far away from the outer bearing race.
