The conveyor idler is an important part of the conveyer, its activity, and the wearability of the idler has a direct impact on the operation efficiency of the conveyer.Conveyor idler as an important part of the belt conveyor, need advanced tooling technology, need strict product quality control, we Henan Excellen Machinery Co., Ltd is a professional set of belt conveyor ready parts manufacturers, we have advanced equipment and perfect production technology and strict quality control system, effective guarantee of conveyor idler quality.
To ensure the conveyor idler processing and assembly quality, the key is to find a has the abundant technical force, perfect technology and equipment, scientific management and good service consciousness of the conveyor idler manufacturer, the manufacturer shall be provided for users from the design calculation, conveyor idler selection, economic and technical analysis to the conveyor design of complete technical services. Reference:
(1) Calculation of the load
The load can be divided into static and dynamic loads. In engineering design, static and dynamic calculation methods are commonly used.The traditional design pays more attention to the calculation of static characteristics. With the development of the dynamic analysis of the belt conveyor, engineers and technicians pay more and more attention to the dynamic characteristics in the design process.
The static load calculation of the conveying idler mainly considers the positive pressure caused by the dead weight of the conveying material and the conveying belt, and the effect of the conveying belt tension should be considered in the bending section of the conveyor, especially in the concave-convex arc section.Trough type conveyor idler force analysis is primarily a load in three conveyor idler on the assignment problem, especially in the convex segmental arc, at present most calculations are among the conveyor idler as the largest stress, according to the material weight and 70% of the conveyor belt weight 40% computation, but the side conveyor idler loading after two bearing force, as well as the larger axial force.
The moving load of the Aida must be considered in the practical selection of the REFERENCE.The moving load is produced by a variety of factors, mainly as follows:
Dynamic load caused by eccentric rotation of the roller shell;
Moving load caused by eccentric rotation and conveyor belt interaction;
Moving load caused by the impact of conveyer and materials when moving;
The moving load caused by the slapping of conveyer belt by transverse bending vibration;
The dynamic load caused by the changes in tension of the conveyor belt to the transition section and the bend section; 6. When the conveying belt in high speed operation is passing by, the material and the conveyer out of shape have a force, especially when the material contains large pieces of material, the impact is the greatest.
The contents of the vessel were loaded by the impact of falling materials.The correct calculation of these loads is very important for choosing and estimating the service life of the amidler.
(2) The workmanship of the reference
The accuracy of the reference refers mainly to the concentricity of the shell and the interior bore at both ends of the reference, and the axial size of each component.If the concentricity is too bad, it will cause the conveyor idler bearing to bite dead, increase the resistance and reduce the service life;If the axial dimensional error of the part is too large, it will form a large axial clearance, resulting in axial movement, damage lubrication and sealing;If the installation quality is not good, it will be deviated, stuck, and intensified wear, etc., which will greatly reduce the service life of the reference.
The manufacturing process will affect the moving load, and the basic reason for the reference is that the wall thickness of the casing is not the same and the quality is not balanced by the radial jerk of the casing.
