托辊运转不灵活的原因
Reasons for Inflexible Operation of Supporting Roller
影响托辊运转灵活程度及其使用寿命的因素主要有以下几方面。
The factors affecting the flexibility of idler operation and its service life mainly include the following aspects.
(1)托辊的制造质量。主要表现在轴承座的刚度不够，难以保证托辊的装配精度，从而制约了托辊运转的灵活性。
(1) Manufacturing quality of idlers. The main manifestation is that the
stiffness of the bearing seat is not enough to ensure the assembly
accuracy of the idler, which restricts the flexibility of the idler
operation.
(2)密封润滑及使用维护。由于皮带输送机的工作环境较为恶劣，一般来说使用现场的粉尘都很大，轴承座的密封形式对托辊运转灵活性影响很大，如果密封不好，污物就容易进入轴承内造成托辊转动不灵活；另外，轴承润滑脂如果采用一般钙基润滑脂很容易变色变干，不能起到很好的润滑作用
(2) Seal lubrication and maintenance. Because the working environment of
belt conveyor is relatively bad, generally speaking, the dust in the
use site is very large, the seal form of bearing seat has a great impact
on the flexibility of idler operation. If the seal is not good, the
dirt will easily enter the bearing and cause the idler to rotate
inflexibly. In addition, if the bearing grease is used with ordinary
calcium-based grease, it will easily change color and dry, and it can
not play a good lubrication. Effect
