Based on the structure of the roller and the standards of our country's belt conveyor, our company has introduced domestic equipment and researched and developed products. It has introduced a wide range of applications, good environmental adaptability, and one-time oil injection. A series of maintenance-free idler rollers with oil injection, contact seal, service life of more than 30,000 hours. Structure When designing this series of rollers, we considered various factors to make it have small starting torque, high efficiency, long life, small maintenance, and large carrying capacity. The roller has ideal static and dynamic balance, which can ensure high-speed application. . The steel tube of the shell and the shaft roller shell adopts the special high-frequency welded pipe for the national standard roller, and the special machine tool for the roller for turning and cutting, and the cold plate stamping and forming the bearing seat, the accuracy grade is ISOM7, which can make the starting torque smaller. The shell and the bearing seat are welded by a CO2 gas shielded automatic welding machine, which makes the overall structure high in strength, and can ensure good accuracy, so that the radial unbalance factor is small. The shaft is cold drawn to ISOH6 to ensure the accuracy of bearing installation.

The idler is a supporting device used to support the conveyor belt and the materials on the belt to ensure the stable operation of the conveyor belt. The rollers can be divided into trough rollers, parallel rollers, self-aligning rollers, buffer rollers, spiral rollers, rollers, vertical stop rollers, etc.; supports include trough-shaped brackets, trough-shaped centering brackets, and flat roller brackets. , The upper and lower flat roller self-aligning brackets are suitable for different materials and different occasions. The weight of the roller does not increase after 24 hours of operation in water; a set of polycarbonate ternary labyrinth seal is installed inside; these protective measures prevent the external atmospheric medium from entering the bearing chamber. Lubricated bearings are lubricated with long-term lithium-based grease. The grease has good stability in different climates. The grease in the bearing chamber can be used throughout the life of the roller. After testing the assembled roller, it is loaded into the testing table, rotating time, agitating the grease to enter the bearing, at the speed of rotation, the amount of radial runout, axial movement, flexibility, performance, dustproof performance, Axial load-bearing capacity, impact resistance, rotation resistance and other indicators will be tested, and a qualified mark will be given when the specified values ​​are met.
