What are the types and characteristics of keyless timing pulley?
Keyless timing pulley does not require keyway processing and is easy to position. The expansion sleeve connection principle is simple and has been widely used in various machines. It is a reliable and effective connection method. The expansion sleeve is used to hold the shaft tightly, with high centering accuracy, suitable for transmitting heavy loads.
1. Taper sleeve keyless timing pulley: The tapered surface is matched with the shaft. When the screw is tightened correctly, the inner surface shrinks inward to fix the shaft, and the outer surface expands outward to clamp the synchronous wheel, realizing keyless connection. It is very convenient to install and disassemble, and has a high synchronous transmission efficiency.
2. Tension sleeve keyless timing pulley: The tension sleeve is matched with the shaft. When the screw is tightened correctly, the inner surface shrinks inward to fix the shaft, and the outer surface expands outward to clamp the synchronous wheel. It can be installed quickly and easily, and does not require the use of key connection, which provides the convenience of quick replacement and maintenance.
3. Clamped keyless timing pulley: The clamped synchronous pulley is fixed to the shaft through a clamping mechanism, and is clamped vertically on the shaft with a fastening screw, so that the inner surface of the hub shrinks inward, thereby tightening the shaft. This design not only simplifies the installation process, but also allows for quick replacement without the need for additional tools.
The above are some common types of keyless synchronous pulleys. These types have their own characteristics. Which type to choose depends on the specific application requirements, such as installation space, load requirements, transmission efficiency and other factors.
