Double Star Leasing Production Line Makes up for the Influence of the Company's Adjustment on the Production Capacity
On June 30, 2015, Qingdao Shuangxing Co., Ltd. issued an announcement that the company signed a one-year asset lease agreement with Deruibao Tire Co., Ltd. and Shandong Yilong Rubber Tyre Co., Ltd. (hereinafter collectively referred to as “the lessorâ€). 》 The main contents of the contract include: Fixed assets lease: (1) All steel tires are equivalent to 1.1 million pieces/year of equipment and molds. (2) Semi-steel tires are equivalent to 3 million pieces/year of equipment and molds. (3) Facilities, such as energy, power, logistics, and public office facilities that are matched with production facilities. (4) For other equipment and molds that have not yet been leased, the lessee has the preferential right to lease. rent: In June 2015, the rent was 3 million yuan. In July 2015, the rent was 3 million yuan. In August 2015, the rent was 4 million yuan. From September 2015, the monthly rent was 5 million yuan. Double Star stated that the fulfillment of the contract will compensate for the company’s impact on the elimination of outdated production capacities and environmental relocations that may affect the capacity of all-steel tires, while gradually increasing the capacity of some semi-steel tires and increasing the ability to meet the needs of customers and users. Performance will not have a major impact.
Conveyor pulleys are used on conveyors to support and deflect the belting through the conveyor structure. Conveyor pulleys also provide a mechanism whereby the conveyor belt can be trained to run (track) true along the conveyor idlers. Generally, pulleys are located at the ends of the conveyor structure and at the take-up arrangement. Pulleys are used to transmit the drive power into the conveyor belt and as such, are subjected to the dynamic belt tension forces in a conveyor.
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.
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.
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.
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.
Hubs:The hubs are fabricated and machined housings which are welded into the end plates.
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.
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.
APPLICATION:
Spherical Roller Bearing are available with heavy duty rollers and cages that are suitable for extreme demand harsh applications such as vibratory screens. Mining Conveyor Machine, and mining bulk Conveyor Pulley. In this sort of aggressive operational environment, the spherical Roller Bearing is the only type that delivers acceptable service life. generally have a longer life span than other bearing types.
Main Models:
