影响摩擦托辊运用功能的主要原因是槽形托辊的内部结构。托辊密封效果欠好：其防水效果较差，而井下皮带机的出产情况是尘埃大、一起用水除尘，尘埃与水是托辊行业界的托辊三大丧命杀手。

The main reason that affects the function of the friction roller is the internal structure of the groove supporting roller. The effect of the roller seal is not good: its waterproof effect is poor, and the production situation of the underground belt machine is large dust, together with water dusting, dust and water are three big death killers of the roller industry circle.

二、摩擦托辊轴同轴度差：因为冷拔光轴出产时因胎具的磨损等要素形成尺度精度不稳定，经常有超支表象，加上在运输过程中易形成弯曲，使槽型托辊轴的同轴度差，摩擦托辊轴两头安装的轴承空隙得不到保证，然后托辊旋转阻力增大，影响运送带托辊的运用寿数。

Two. The coaxiality of the shaft of the friction roller: because of the instability of the scale precision formed by the wear and tear of the prom when the cold drawing shaft is produced, it often has the hyperbranched representation, and it is easy to bend in the course of transportation, so that the coaxiality of the slot type roller shaft is poor, and the shaft clearance of the two ends of the friction roller shaft is not guaranteed, and then the roller is rotating. Turn the resistance increases, impact roller conveyor belt using his.

三冲压时轴承座不圆或与筒皮合作处的端面不平等疑问均易形成与筒皮焊接后两头轴承座的不同轴，致使摩擦托辊轴承游隙减小，旋转阻力增大，滚动不灵敏。运送带调心托辊是带式运送机的重要构成部件，主要肩负着承载运送物料的效果，在皮带机运输过程中承受68%以上的阻力。

Three when the bearing seat is not round or the end face of the cylinder skin is unequal, it is easy to form the different axis of the two head bearing pedestal after the tube welding, which makes the friction roller bearing clearance decrease, the rotation resistance increases, and the rolling is insensitive. The belt conveyer belt roller is an important component of the belt conveyor. It bears the effect of carrying the material and bears more than 68% resistance during the belt conveyor.

四、影响摩擦托辊运用寿数的本源在于其内部结构因为井下运用条件恶劣，摩擦调心托辊的运用寿数通常仅可达15000h 摆布。

Four. The origin of the application of the life number of the friction roller lies in its internal structure because the downhole conditions are bad, and the application life of the friction adjusting roller is usually only 15000h.

摩擦托辊通常是以托辊组的局势呈现的，它分为上、下两种摩擦托辊组，摩擦托辊通常是用一个摩擦头和一个一般托辊衔接而成的，制造技术比较复杂，成本较高。在保护过程中，首要咱们要看托辊外表的磨损情况，假如磨损严峻的话必须要替换了，假如不及时替换的话就会磨皮带。

The friction roller is usually presented in the situation of the roller group. It is divided into two groups of upper and lower friction rollers. The friction roller is usually connected by a friction head and a general roller. The manufacturing technology is more complex and the cost is higher. In the process of protection, we should look at the wear of the surface of the roller. If the wear is serious, we must replace it. If it is not replaced in time, the belt will be worn.
