浅析托辊配件的选购
托辊是影响皮带输送机使用寿命的主要部件之一。按托辊的不同用途可分为承载托辊,回程托辊和专用托辊三种。专用托辊又可分为缓冲托辊,调心托辊和防偏挡辊等。若按托辊的支承方式又可分为支架式和悬挂式。鉴于托辊的重要性,昱音公司从托辊材质、托辊密封技术、托辊润滑脂和托辊轴承四个方面临托辊进行了重大技术改进,以进步托辊的使用寿命。
Idler is one of the main parts that affect the service life of belt conveyor. According to the different uses of idlers, they can be divided into three types: carrying idlers, backhaul idlers and special rollers. Special idlers can be divided into buffer rollers, aligning idlers and anti bias rollers. It can be divided into bracket type and suspension type according to the supporting manner of roller. In view of the importance of the roller, Yu Yin company has made great technical improvements from four aspects of the material of the roller, the sealing technology of the roller, the grease of the roller and the bearing of the roller, in order to improve the service life of the roller.

浅析托辊配件的选购及改进技术
A brief analysis of the selection and improvement of the accessories of the roller
1、托辊材质:采用优质45号钢材。在有酸碱等侵蚀性物质的场所使用,管体锈蚀严峻,表面锈蚀将加速输送带的磨损,为解决这一题目,我们采用入口不锈钢、尼龙、陶瓷等材质。
1, roller material: high quality No. 45 steel. In the place of acid and alkali and other corrosive substances, the corrosion of the tube is severe and the surface rust will accelerate the wear of the conveyor belt. In order to solve this problem, we use the material of the entrance stainless steel, nylon, and ceramics.

2、托辊的密封:托辊常常在多尘前提下工作,空载托辊有时还在煤泥水中运转,室外皮带输送机的槽型托辊两侧也会因雨水沿轴端缝隙渗透,引起轴承防尘盖及其保持架锈蚀,润滑脂变质。我们采用防尘防水密封结构设计,进步托辊的使用寿命。
2, the seal of the roller: the roller often works under the condition of dusty. The no-load roller sometimes runs in the slime water. The groove type roller of the outdoor belt conveyer also permeates the cracks along the shaft end, causing the bearing dust cover and its cage to rust and the grease metamorphic. We adopt the design of dustproof and waterproof sealing structure to improve the service life of idlers.

3、托辊润滑脂:托辊应使用锂基润滑脂,其滴点高,油脂不易流失,也不易变质结块,可延长托辊使用寿命,减少磨擦阻力。
3, roller lubricating grease: the roller should use lithium base grease, its drop point is high, oil is not easy to drain, and it is not easy to deteriorate caking. It can prolong the service life of the roller and reduce friction resistance.

4、托辊轴承:轴承失效主要是因为水分,粉尘或异物侵入,使轴承锈蚀,润滑脂变质所引起。加大滚珠直径,采用单面开放式尼龙保持架,加大轴向游隙的托辊专用轴承能有效地防止轴承卡滞。其寿命为普通轴承的五倍以上,功率消耗可降低18%左右。
4, roller bearings: bearing failure is mainly due to moisture, dust or foreign matter intrusion, so that bearing corrosion, grease deterioration. Increase the diameter of the ball, adopt the single face open nylon cage, and increase the axial clearance of the idler bearing can effectively prevent the bearing from clamping. Its life span is more than five times of the normal bearing, and the power consumption can be reduced by about 18%.
