Tapered Idlers Have Strong Wear Resistance And Characteristics Are Introduced

The tapered idler is one of the idlers, which is mainly used in conveyor equipment to support the conveyor belt and the weight of the material. The operation of the tapered idler must be very flexible and reliable, which reduces the friction between the conveyor belt and the idler, which plays a very critical role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. The conical idler is also the most important component of the belt conveyor, with a wide variety, the quantity accounts for about 35% of the total cost of a whole belt conveyor, resulting in more than 70% of the resistance, so the quality of the conical idler has a very important role for the belt conveyor.

Conical idler has a low coefficient of friction, very wear-resistant, not easy to operate the belt, but also has excellent self-lubrication, in the whole process of use, no need to inject oil and can operate under harsh environmental conditions, not easy to jam, has good anti-magnetic characteristics, but also has strong corrosion resistance and aging resistance, and compared to the corrosion of weak alkali and organic solvents, non-toxic and non-polluting can withstand repeated impact and vibration. The conical idler itself is light in weight only one-third of the metal parts, with easy installation, low maintenance rate and low noise, stable operation, energy saving, can improve the use cycle of the conical idler dustproof, good waterproof performance, used in a dusty environment, not easy to enter the water. The conical idlers produced by Yuyin have a complete range of specifications and models, which can be produced in diameter, length, and can be customized according to the needs of special specifications.

Due to the high hardness of the idler. Special grinding wheels and automatic grinding machines are used. After the grinding is completed, the eddy current flaw detector and ultrasonic flaw detector are used to carry out the composite flaw detection of the roll surface. After the idler of the normal lower machine is grinded, a slight hot crack can be left on the machine. The idler under the rolling accident needs to increase a certain amount of grinding on the basis of grinding to remove the cracks on the roll surface, so it is necessary to use different types of bearings. Compared to general-purpose bearings, idler bearings are an important component in the working base of rolling mills. The tapered up-aligning idler should rotate flexibly without jamming. Due to the different structures and working conditions of various rolling mills, idler bearings have the following characteristics: the bearing seat size should not be larger than the minimum diameter of the roll body, and the working load is large. Since the roller body diameter of the idler should ensure strength. The length of the roll neck is also short, so the unit load on the roller neck is large. Usually the unit pressure of idler bearings is 24 times higher or even higher than that of general purpose bearings, while the PV value (product of the unit pressure and linear velocity of the bearing) is 3-20 times that of ordinary bearings.
