长沙正圆动力配件厂铸造车间用于皮带运输机和斗式提升机上的普通型轴承座,因密封不良往往使轴承提前损坏。为解决此问题,这两种设备主动轮的轴承座改用一种特殊的密封方式,可使寿命延长数十倍。本人在本刊1984年第3期上已经介绍过。但这种轴承座不宜用在从动轴上,因为从动轮经常要调整运输带的松紧或解决皮带跑偏问题。为实现调整换向,轴承座2与轴承5配合处应留有较大的径向间隙(1～1.5mm),轴承也采用双球轴承,如图
Changsha Zhengyuan Power Parts Casting shop for belt conveyor and bucket elevator on the common type of bearing seat, due to poor sealing often make the bearing damaged in advance. In order to solve this problem, both types of equipment take the initiative to change the bearing housing with a special seal, you can extend the life expectancy of dozens of times. I have in the first issue of 1984 1984 has been introduced. However, this bearing should not be used in the driven shaft, driven wheels often have to adjust the belt tension or solve the belt deviation problems. To achieve the adjustment of commutation, bearing seat 2 and bearing 5 should be left with a larger radial clearance (1 ~ 1.5mm), the bearing also uses double ball bearings, as shown
