Carbon Steel Half Round Key

Carbon steel half round key not only ensures a stable connection between the shaft and the hub, realizing synchronous rotation and torque transmission, but also has many advantages in the process of installation and use, and is an indispensable and important part of the mechanical transmission device.

Working principle

When the shaft rotates, the carbon steel half round key transmits the torque from the shaft to the hub through the interaction between the two sides and the side of the key way of the hub, and then drives the hub and the parts connected to it to rotate synchronously. The fit between the half round key and the key way generally adopts a tighter transition fit to ensure that no relative sliding occurs during the torque transmission process, thus ensuring the reliability of power transmission.

Application scenarios

Carbon steel half round key is widely used in various mechanical transmission devices. In some small motors, reducers, shafts and gears, pulleys are more common in the connection, because it can automatically adapt to a certain angle deviation, installation and disassembly is relatively convenient, for maintenance and overhaul work is more favorable. In some hand-held tools, such as electric drills, electric screwdrivers, etc., the motor output shaft and the transmission components of the connection is also often used half-round key to meet the equipment in different working conditions, stable transmission of torque needs.

Product advantages

The installation process of the carbon steel half round key is extremely easy. Due to its unique design, it can oscillate to a certain degree in the key way. This feature makes the half-round key relatively undemanding in terms of shaft-hub alignment and makes it easy to install the half-round key in place, even in cases where the alignment accuracy is not high.

In the actual mechanical transmission process, slight angular deviations may occur between the shaft and the hub. Carbon steel half round key can well adapted to such angular variations and maintain reliable operation in shaft-hub connections with slight angular deviations.

Product maintenance

In order to ensure the connection performance and service life of the carbon steel half round key,we must necessary to check the half-round key regularly during the use. The contents of the inspection include whether the coordination between the half-round key and the key way is tight, whether there is loosening phenomenon; whether the surface of the half-round key is worn, deformed or damaged and so on. If the half-round key is found to be worn or deformed, it should be replaced in a timely manner so as not to affect the stability and reliability of mechanical transmission.
