What Is a Wedge Pulley?
Pulleys are pulley-shaped parts used in various machines and equipment, including automobiles. Normally, a belt is used to transmit power from a power source, such as a machine, and pulleys are used in combination with the belt.
A wedge pulley is used in combination with wedge belts, which are narrow V-belts.
Wedge belts create more frictional force than other types of belts of the same width. As a result, they provide greater transmission capacity, enabling high-speed and high-power transmission.
Uses of Wedge Pulleys
When using a belt to transmit power, it is necessary to select a pulley that matches the belt specifications. Wedge pulleys are used in combination with wedge belts.
The use of wedge belts in combination with wedge pulleys can save space and energy in the transmission system. Furthermore, wedge belts have a longer service life than normal belts and have been widely used in recent years. For example, wedge belts are used in various fields such as large pumps, compressors, forging presses, casting machines, paper manufacturing machines, crushers, hammer mill generators, band sawing machines, large machine tools, vibrating rollers, grinders, and freezers.
Principles of Wedge Pulleys
Wedge pulleys are used in combination with wedge belts to transmit power from a power source.
Wedge belts, being wedge-shaped, create a stronger frictional force than other common belt types of the same width. Therefore, when wedge belts are used with wedge pulleys, the transmission capacity is greater than when flat or V-belts are used with standard pulleys, allowing for high-speed, high-power transmission. As a result, the space required for the transmission equipment can be reduced compared to the space required for standard belts, thus realizing size reduction of the equipment.
Also, the use of wedge pulleys and wedge belts allows for efficient power transmission, which also saves energy.
In addition, the efficient operation also extends the life of the belt. Thus, the use of wedge pulleys in combination with wedge belts offers various advantages over the use of conventional pulleys and flat belts or V-belts.
