The transmission belt is the power generated by the rotation of the motor or engine of the prime mover, and is transmitted to the mechanical equipment through the belt through the belt, so it is also called the power belt. It is the core connecting component of electromechanical equipment, with a wide variety of uses and extremely versatile uses. From giant motors as large as several thousand kilowatts to small motors as small as less than one kilowatt, even including precision machinery such as home appliances, computers, robots, etc., are inseparable from the transmission belt. Its biggest feature is that it can be freely shifted, far and near transmission, simple structure, easy to replace. Therefore, there are transmission belts from the original machinery to modern automatic equipment. The product has undergone many evolutions and the technology has become mature. In the mid-17th century, the United States began to use aerial ropeways to transport bulk materials; in the mid-19th century, various modern conveyor belt conveyors appeared one after another. In 1868, a belt conveyor appeared in the United Kingdom; in 1887, a screw conveyor appeared in the United States; in 1905, a steel belt conveyor appeared in Switzerland; in 1906, an inertial conveyor appeared in the United Kingdom and Germany. Since then, the conveyor belt conveyor has been continuously improved by the influence of technological progress in machinery manufacturing, motors, chemical and metallurgical industries. It has gradually evolved from the completion of internal transmission in the workshop to the completion of material handling within enterprises, between enterprises and even between cities. An indispensable part of the mechanization and automation of material handling systems.
Conveyor belts are generally classified according to the presence or absence of traction members.
Conveyor belts with traction members generally include traction members, load-bearing members, drive devices, tensioning devices, redirection devices, and support members. The traction element is used to transmit traction force, and can use conveyor belts, traction chains or steel ropes; the bearing member is used to hold materials, and there are hoppers, brackets or spreaders, etc.; the driving device powers the conveyor, which is generally composed of electric motors, reducers and Brake (stop), etc.; the tensioning device generally has two types of screw type and heavy hammer type, which can maintain a certain tension and sag of the traction member to ensure the normal operation of the conveyor belt; the support member is used to support the traction member or load Components, such as idlers and rollers, can be used.
This type of conveyor belt equipment has a wide variety, mainly including belt conveyors, plate conveyors, trolley conveyors, escalators, moving walkways, scraper conveyors, buried scraper conveyors, bucket conveyors, bucket elevators , Hanging conveyors and overhead ropeways, etc.
The structural composition of conveyor belt equipment without traction parts is different, and the working components used to transport materials are also different. Their structural characteristics are: the use of the rotating movement or reciprocating movement of the working member, or the use of the medium in the pipeline to make the material forward. For example, the working component of a roller conveyor is a series of rollers, which rotates to convey materials; the working component of a screw conveyor is a spiral, and the screw rotates in a trough to push materials along the trough; the work of a vibrating conveyor The component is a material trough, and the material trough reciprocates to convey the materials placed therein.
