托辊运转不灵活的主要原因及解决措施

Main Reasons and Solutions for Inflexible Operation of Supporting Roller

皮带输送机中托辊的数量很多，是输送机重要的零件之一，其价格约占输送机总价格的25%左右，托辊的维修和更换费用也是皮带输送机运营费用的重要组成部分，托辊运转情况对整个输送机的运行阻力、功率消耗、托辊和输送带的使用寿命、维护工作量及运输成本都有很大影响。

There are many supporting rollers in belt conveyor, which are one of the important parts of the conveyor. The price of supporting rollers accounts for about 25% of the total price of the conveyor. The maintenance and replacement cost of supporting rollers is also an important part of the operating cost of belt conveyor. The running condition of supporting rollers has an important effect on the resistance of the whole conveyor, power consumption, service life of supporting rollers and conveyor belts, maintenance workload and transportation cost. They all have a big impact.

1托辊运转不灵活的原因

1. Reasons for the Flexibility of Roller Operation

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.

2. Solution Measures for Inflexible Operation of Supporting Roller

(1)在托辊的制造工艺上保证规定的精度要求，例如冲压轴承座的内孔精度要达到3级，管体两端的尺寸公差、同轴度和椭圆度都必须符合国标，不能超差。对产品要有严格的质量检验，保证出厂产品全部合格。

(1) To ensure the specified accuracy requirements in the manufacturing process of idlers, for example, the accuracy of the inner hole of the stamping bearing seat should reach grade 3, and the dimension tolerance, coaxiality and ellipticity of both ends of the pipe body must conform to the national standard and not exceed the tolerance. Strict quality inspection should be carried out to ensure that all products are qualified.

(2)密封润滑方面，设备要配备合格的润滑材料，如采用锂基润滑脂，可以改善轴承的润滑情况，这对延长托辊的使用寿命是非常必要的。

(2) In sealing lubrication, equipment should be equipped with qualified lubricating materials, such as lithium-based grease, which can improve the lubrication of bearings, which is very necessary to prolong the service life of idlers.

(3)轴承座采用向心球轴承支撑、塑料密封环迷宫式密封结构，这样既可保证托辊工作时受力合理，同时防尘效果好，阻力小，且装拆方便，便于维护，可有效降低输送机的运营成本。

(3) The bearing base adopts the labyrinth sealing structure of centripetal ball bearing support and plastic sealing ring, which can ensure that the supporting rollers work under reasonable stress, good dust-proof effect, low resistance, convenient assembly and disassembly, easy maintenance, and can effectively reduce the operation cost of the conveyor.
