Merchandise Description

Head sheave / hoisting sheave / sheave pulley / manual pulley for mine hoist 

Item Introduction
 Xihu (West CZPT ) Dis. wheel gadget can transport the whole under the premise of swimming spherical and mounted wheel adopts integral cast joint composition, wheel hub, wheel rim for solid steel resources, spoke for the channel steel, soon after welding the entire annealing method once more. 

Taking into consideration the substitute bearing maintenance practical, depart replace bearing eliminate space, information wheel unit composition adopted eccentric format. 

Xihu (West CZPT ) Dis. shaft using middle carbon alloy steel forging total, adopting the framework of the cast joint pulley, equipped with PVC or nylon liner, safeguard the wire rope. 

Imported or domestic spherical roller bearings, also can install bearing temperature measuring element. 

In get to prolong the support lifestyle of wire rope, rim inside of wedge liner with dress in-resisting, withstand voltage, using D660 (1571) or nylon liner. 

one) eccentric layout: on a single side of a winding wheel have replaced bearing dismantling place, can not eliminate the pulley mechanism, only for bearing upkeep and alternative. 
2) symmetry format: relative with four wheels on equally sides of the two bearing seat is symmetrical, but need to substitute the bearing shell, only to get rid of the pulley system. 
 
sheave pulley and the widespread malfunction and technological guide wheel 

1) to the issue of aged construction pulley sliding bearing to burn off tile should increase lubrication way Simply because of the pulley is set up on the derrick, everyday upkeep inconvenience, need to incorporate temperature alarm gadget, so as to timely upkeep to stop the tile burning failure, or the first sliding bearing replacement into rolling bearing structure 

two) for aged framework pulley rope groove without having liner, can no CZPT er add padding on the first rope groove, need to have to adjust a gasketed pulley, adjacent assembly size can continue being motionless, and installation 

3) for mountain transportation difficulties or have some problems in roadway transportation in underground mine, the pulley is (manual wheel) modify the structure into two or 4 and a 50 % of head sheave.

 

Fastened or Class 1 pulleys have a fastened shaft. That is, the shaft is “mounted” or anchored in area. A set pulley is a pressure used to alter the course of the rope (known as a belt because it can make a single change). Mounted pulleys have mechanical positive aspects of set pulleys. Active pulleys or 2-phase pulleys have free of charge shafts. That is, the axis can move “freely” in area. Shifting pulleys are utilized to convert forces. Active pulleys have the mechanical gain of two pulleys. That is, if a single finish of the rope is stationary, pulling the other stop of the rope will exert two times the pressure on the object hooked up to the pulley. A composite pulley block is a blend of a fixed pulley block and a movable pulley block. Blocks – Blocks are composite pulleys the place a number of pulleys are mounted on each and every axle, further introducing to the mechanical edge. Pulleys can alter the direction of the pressure.
