    Here I come to tell you about the idler technical knowledge.

    With the belt of development, from the structure to the idler roller group there are always new types of changes, in the face of so many idlers and belt idlers form, how to properly choose the right type of roller group is a problem, the heavy transport roller group with the basic requirements are: use of reliable, rotary drag coefficient is small, low cost, has sufficient bearing capacity; heavy roller conveyor Suppliers common structure consists of tubular body, bearing housings, bearings, shaft and seal structure, bearing roller tube disposed in the interior, from the ends of the shaft idler roller bracket support, generally by the seamless tube or welded steel pipe manufacturing, steel pipe manufacturing Because the tube wall thickness of the pipe is uneven, generating additional dynamic load operation, the belt vibration, both the bearing and seals premature destruction, generally apply only to a conveyor running at low speed, uniform wall welded steel, smooth suitable for high-speed operation, bearing with cast-in and punch-in and Bakelite Gabe are three advantages of greater thickness, rigidity, high precision mating surfaces, roller rotation flexibility, but the weight is greater than the cost high, stamping bearings, light weight, easy to manufacture, low cost, but thin rigid plate is small, easy to deform, disassembly easily damaged, conveyor belt roller ball bearings are generally used in recent years tended to use a large bearing clearance, to improve the working condition of bearings, play roller reduces resistance and reduce the manufacturing cost of idlers role; rubber conveyor belt factory sealed roller directly affects the structure of the resistance and the idler roller life, roller sealing with labyrinth seals, grease except for lubrication, but also play a role in sealing, calcium-based grease lubricant life is short, usually around six months up to three years have occurred on aging; roller by different uses can be divided into ordinary and special roller bearing roller, roller bearing is generally in the normal segment of upper branch and lower branch idlers, their role is to support the conveyor and materials, special rubber roller conveyor belt is the role of the transition guide rollers are mounted in groups on the conveyor, the roller group can consist of a single flat-shaped idler roller and two, three idler trough idlers, trough idlers level intermediate rollers arrangement, the most common of the three idler rollers set equal length and arranged in the same plane, the three rollers is not in the same horizontal plane is the side trough roller idler roller mounted on the horizontal plane near the other This roller group advantages are: to reduce the height of the roller frame, reducing the distance between the equivalent roller group, low stiffness for the conveyor and place a small space, is an energy roller group , the use of two intermediate conveyor rollers to strengthen the support, thereby reducing the bending and nylon conveyor belt sag
