天輪襯塊
Hoist Sheave lining
天輪襯塊主要是防止天輪與鋼絲繩直接接觸時(shí)產(chǎn)生的摩擦,因此對保護鋼絲繩起著(zhù)非常重要的作用。鋼絲繩在運行時(shí)會(huì )產(chǎn)生自轉,如果摩擦系數過(guò)高,會(huì )妨礙鋼絲繩的旋轉,損傷鋼絲繩和。對于這種情況,鋼絲繩必須以盡可能小的阻力導入豎井,以減小扭矩和旋轉應力。
我司專(zhuān)業(yè)生產(chǎn)各種型號不同材質(zhì)的天輪襯塊產(chǎn)品,主要材質(zhì)有超高分子、改性PP、PVC、聚氨酯、尼龍等, 并可提供各種材質(zhì)和尺寸的定制加工。
我司采用了粘均分子量在150萬(wàn)以上的線(xiàn)性結構材料(普通材料的分子量?jì)H2~30萬(wàn))制作而成的天輪、導向輪襯塊,具有如下特性:
1.優(yōu)異的耐磨性;
2.良好的抗沖擊性能;
3.良好的自潤滑性;
4.超高的拉伸強度;
5.良好的耐腐蝕性、耐水性;
6.良好的穩定性;7.良好的抗低溫性能。
The hoist sheave lining is mainly used to avoid the friction when head sheave directly contact steel wire cases. So it plays vital role in protecting steel wire. The steel wire will rotate in operation. If the friction factor is much higher,it will disturb steel wire rotating and damages the steel wire. In this situation, The resistance of the wire rope must be as small as possible to import the shaft, to reduce the torque and rotation stress.
We specialize in designing each model and different materials head sheaves and the most materials are included Ultrahigh molecular, modified PP, PVC, pu, nylon, etc. And we also can supply OEM products with different models and materials.
Pulley, and guide wheel liner which are adopted by linear structure materials whose the sticky molecular weight is more than 1.5 million (the molecular weight of ordinary materials only twenty thousand to three hundred thousand has the following features:1、Excellent wear resistance; 2、Good impact resistance; 3、Good self-lubricant; 4、good self-lubricant; 5、good anticorrosion and water resistance; 6、good stability; 7、good resistance to low-temperature.
