渣浆泵中滚动轴承部件常用结构

(1) 悬臂式泵轴承部件结构

图5-21是托架式轴承部件结构，托架下方生有底脚，而泵体没有底脚，而被悬空装在托架上，用润滑脂润滑轴承。这种结构适用于被输送液体温度低于80C，转速低于3000r/min的小功率泵中，当托架后部装有两个轴承时，可用于皮带传动。

图5-22是悬架式轴承部件结构，悬架上没有底脚，而泵体上设地脚，悬架被悬空装在泵体上。用润滑油来润滑轴承。悬架下方没有冷却水套，用来冷却润滑油。如果输送液体温度不高时，可没有冷却水套。悬架中，后面装有一对角接触球轴承或其它推力轴承，轴承内圈用小圆螺母压紧在轴承上，轴承外圈与轴承压盖间约有0. 1 ~0. 2mm的间隙可用来承受一定的轴向载荷。悬架式轴承部件结构也可以采用风冷结构，即悬架下面没有冷却水套，而在悬架后面加一个风扇，悬架上带散热片，如同电机的风扇结构。悬架式轴承部件结构可以用

Common structure of rolling bearing parts in slurry pump

(1) cantilever pump bearing component structure

Figure 5-21 shows the structure of bracket type bearing components. There are feet under the bracket, but the pump body has no feet, so it is suspended on the bracket and lubricated with grease. This kind of structure is suitable for the small power pump with the temperature of the delivered liquid lower than 80C and the rotating speed lower than 3000r / min. when two bearings are installed at the rear of the bracket, it can be used for the belt drive.

Figure 5-22 shows the structure of suspension bearing components. There is no foot on the suspension, while the pump body has foot, and the suspension is suspended on the pump body. Lubricate the bearings with lubricating oil. There is no cooling water jacket under the suspension to cool the lubricating oil. If the temperature of conveying liquid is not high, there is no cooling water jacket. In the suspension, a diagonal contact ball bearing or other thrust bearing is installed at the back. The inner ring of the bearing is pressed on the bearing with a small round nut. There is about 0.1-0.2mm clearance between the outer ring of the bearing and the bearing gland to bear certain axial load. The suspension bearing component structure can also adopt air cooling structure, that is, there is no cooling water jacket under the suspension, and a fan is added at the back of the suspension, and the suspension has a radiator, just like the fan structure of the motor. Suspension bearing component structure can be used

When the rotating speed is high, the power is high or the temperature of the transported liquid exceeds 80 ° C. Slurry pump manufacturer
