Drive pulley provides a driving force for conveyors. Its diameter is usually larger than others pulleys in case to increase the pulley life and traction. According to customers' requirements, We can supply pulleys with hot vulcanized rubber lagging and cold bonded lagging, the lagging can be plain or with grooves. Different patterns of grooves, like herringbone or diamond, is suitable for dirty or wet conditions. A ceramic lagging can enhance the friction between the pulleys and belt. Thus a lagging pulley can effectively improve the operation status of the conveying system and protect the metal pulley from wearing.
Bend Drum: is used for changing the running direction of the conveyor belt or increasing the surrounding angle of the conveyor belt on the driving roller, and the roller adopts a smooth rubber surface . The drum shaft shall be forgings and shall be nondestructive tested and the inspection report shall be provided.
The Components of Pulley:
| 1. Drum or Shell:The drum is the portion of the pulley in direct contact with the belt. The shell is fabricated from either a rolled sheet of steel or from hollow steel tubing. |
| 2.Diaphragm Plates: The diaphragm or end plates of a pulley are circular discs which are fabricated from thick steel plate and which are welded into the shell at each end, to strengthen the drum.The end plates are bored in their centre to accommodate the pulley Shaft and the hubs for the pulley locking elements. |
| 3.Shaft :The shaft is designed to accommodate all the applied forces from the belt and / or the drive unit, with minimum deflection. The shaft is located and locked to the hubs of the end discs by means of a locking elements. The shaft and hence pulley shafts are often stepped. |
| 4.Locking Elements:These are high-precision manufactured items which are fitted over the shaft and into the pulley hubs. The locking elements attach the pulley firmly to the shaft via the end plates. |
| 5.Hubs:The hubs are fabricated and machined housings which are welded into the end plates. |
| 6.Lagging: It is sometimes necessary or desirable to improve the friction between the conveyor belt and the pulley in order to improve the torque that can be transmitted through a drive pulley. Improved traction over a pulley also assists with the training of the belt. In such cases pulley drum surfaces are `lagged` or covered in a rubberized material. |
| 7.Bearing: Bearings used for conveyor pulleys are generally spherical roller bearings, chosen for their radial and axial load supporting characteristics. The bearings are self-aligning relative to their raceways, which means that the bearings can be 'misaligned' relative to the shaft and plummer blocks, to a certain degree. In practical terms this implies that the bending of the shaft under loaded conditions as well as minor misalignment of the pulley support structure, can be accommodated by the bearing. |
Our Products:
| 1.Different types of Laggings can meet all kinds of complex engineering requirements. |
| 2.Advanced welding technology ensures the connection strength between Shell and End-Disk. |
| 3.High-strength Locking Elements can satisfy torque and bending requirements. |
| 4.T-shape End-Discs provide highest performance and reliability. |
| 5.The standardized Bearing Assembly makes it more convenient for the end user to replace it. |
| 6.Excellent raw material and advanced processing technology enable the shaft can withstand enough torque. |
| 7.Low maintenance for continued operation and low total cost of ownership. |
| 8.Scientific design process incorporating Finite Element Analysis. |
Our Workshop:
| MACHINE:We have advanced laser cutting machines, a complete set of intelligent sheet metal forming equipment, robot welding and other processing and testing equipment. |
| PAINTING: We use electrostatic spraying to ensure variety, model and quality of coatings, thinners and curing agents should meet the design requirements and the current relevant national standards. The steel surface should be free of welding slag, welding scars, dust, oil, water and burrs before painting. No mispainting or omission, and the coating should be free of peeling and rust. Inspection method: observation and inspection. Uniform brushing, consistent color, no wrinkles,sagging and bubbles, good adhesion, and the color separation line should be clear and neat. |
| DELIVERY:The goods and product factory certificate, installation and use instructions and drawings, a full set of connectors. After the equipment arrives at the site, the company immediately arranges professional and technical personnel to guide the installation on site to provide customers with satisfactory services. |
| PACKAGE:Packed with steel frame or wooden box, according to the standardfor trade export or according to the special requirements of customers. |
