Dezhou Hengda friction pulley manufacturers share issue of Texas Hengda pulley manufacturers in the years of production, for the belt pulleys and friction problems have mastered before a fiery pure blue belt pulley under the action of friction, will Expand the various modes of operation. In the belt drive, the friction between the belt and pulley will be smaller Bushes price, belt will slip on the pulley, not the normal operation of the machine, so you can strap tightly, increasing the pressure on the belt pulleys, thereby increase the friction between the belt and the pulleys. If the capstan is rotated counterclockwise, then the relative movement of the belt pulley is the clockwise direction of the trend, it is possible to determine the direction of the capstan effect on the static friction of the belt is counterclockwise. Driving wheel and the driven wheel exchange position, or direction of rotation of the drive wheel counter-clockwise. Similarly understood, the capstan frictional force acting on the belt is counterclockwise Bushes model, the driven wheel frictional force acting on the belt is in a clockwise direction. Pulley casting porosity defect analysis for the production of various defects pulleys, pulley large castings, timely analysis and discussion Bushes manufacturers, find out the reasons of manufacturing defects, and to take the necessary preventive measures, which pulley casting quality is very important work. Due to the large pulley casting defects caused by casting repair, and other economic losses caused by the retirement, usually accounts for 5% of gross ·· 10% foundry, so casting has flaws, especially common multiple defects, a careful analysis of relevant personnel organization discussion, find out the real reason, and to take practical and effective preventive measures to prevent such defects appear again, for improving the quality of casting large pulley, increase economic efficiency is very important. spa Bushes | Beijing Bushes | Hengda machinery provided by the Texas Hengda Machinery Co., Ltd ..
