Our factory can produce various specifications and models of GB pulley. GB pulleys can be applied according to different cross-sectional dimensions of the V-belt or wheel size into the O-groove pulley, A pulley type, B-type pulley, C-type pulley, D-belt pulley, E-type pulley; follow straight holes and pulley shaft hole different cone straight into the hole and cone pulley pulley into two categories, according to the outer diameter OD from 63mm to 1450mm pulley Bushes processing, the number of slots from 1-12 slots, can be divided into single groove pulley, dual pulley three grooved pulleys supply Bushes, multi-groove pulley, sheave, gray iron pulleys, cast iron pulleys, V-belt pulley, pulleys, etc. Large thousands of different permutations and combinations of standard models of pulleys, we can design according to your actual application the parameters of the indicators for the specific needs of your manufacturing suits your needs GB pulley. I plant manufacturing equipment, strong technical force, advanced production technology, testing means complete, perfect quality management system, all kinds of national standard pulley superior quality, reasonable price, timely delivery, fast efficient service, welcome new and old customers call communication and cooperation and seek common development plans. Guangzhou State hung pulley manufacturers in the years of production, for the belt pulleys and friction problems have mastered before a fiery pure blue belt pulley friction in effect, will launch various modes of operation. In the belt drive, the friction between the belt and the pulley becomes smaller, the belt will slip on the pulley, so that the machine can not operate normally Bushes selection, so that the belt can be tightly, increasing the pressure on the belt pulleys, thereby increasing the frictional force 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 driven wheel Bushes exchange position, direction of rotation of the driving wheel or counterclockwise. Similarly understood, the capstan frictional force acting on the belt is counterclockwise, the driven wheel frictional force acting on the belt is in a clockwise direction. Bushes | Bushes | State hung machinery provided by the state-hung Machinery Co., Ltd. in Guangzhou. Hung Machinery Co., Ltd. Guangzhou state (www.gzbhjx.com) strong, credible, in Guangzhou casting industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the state machinery and you work hung into the brilliant, for a better future!
