运转进程托辊轴承坏死 , 与胶带硬性冲突过热加快老化, 严峻的可致使胶带焚毁。
托辊运转质量对胶带和驱动设备的运转效果和使用寿命发挥重要影响, 托辊数量多, 毛病发作频频,主要表现有以下两方面。
The operation quality of idler plays an important role in the operation
effect and service life of belt and driving equipment. There are a large
number of idler and frequent faults, mainly in the following two
aspects.

1、运转进程托辊轴承坏死 , 与胶带硬性冲突过热加快老化, 严峻的可致使胶带焚毁。
1. In the process of operation, the idler bearing is necrotic, which
conflicts with the belt rigidly. Overheating accelerates aging, which
may lead to the burning of the belt.
形成这一表象的首要原因: 托辊轴承质量不高 , 光滑功能差; 为防止因托辊质量影响胶带运转事端的发作, 采纳定时或不定时替换托辊等办法 ,
确保设备和出产的正常进行。别的, 可对于托辊运转质量和稳定性与出产厂家进行联合研讨攻关 , 不断提高托辊产品质量。胶带巡视力度不行,
职责追查准则执行不到位; 加强胶带沿线设备的巡视力度, 特别是长距离胶带设备的巡视工刁难削减胶带机运转事端发作具有极其重要的现实意义。
The main reasons for this phenomenon are: the quality of the idler
bearing is not high, and the smooth function is poor; in order to
prevent the occurrence of troubles caused by the quality of the idler
affecting the belt operation, measures such as replacing the idler
regularly or irregularly are adopted to ensure the normal operation of
the equipment and production. In addition, the quality and stability of
idlers can be studied with manufacturers to improve the quality of
idlers. It is of great practical significance to strengthen the
inspection of the equipment along the belt, especially the patrol of the
long-distance belt equipment, and reduce the occurrence of accidents in
the operation of the belt conveyor.
2、运转进程中托辊掉落 , 被回程胶带卷至滚筒形成胶带破穿或撕裂 , 这种毛病后果严峻, 经济损失大。尤其是没有卡槽的托辊, 轴端面与支架外外表平齐, 若是支架支撑强度差, 在轰动等外力效果下支架变形, 托辊很容易掉落。
2. In the process of operation, the idler falls down and is rolled to
the drum by the return belt, resulting in the breakage or tearing of the
belt, which has serious consequences and great economic losses.
Especially for the idler without slot, the shaft end face is flush with
the outer surface of the support. If the support strength is poor and
the support is deformed under the effect of external force, the idler is
easy to fall.
