Drum-shaped gear couplings are difficult to install because the sleeve and shaft are in transitional fit, and the sleeve is made of cast steel. Is there any good way to install it?
With a gap of 0.0 millimeters, it is impossible to install vertically if it is manually knocked in. If the shaft sleeve is not very large, you can use the oil heating method to put the shaft sleeve in an iron drum containing organic oil and heat it to 200 degrees Celsius From left to right, remove the shaft sleeve and install it on the shaft. It is especially easy to install. The gap between the shaft and the shaft hole is standard. Do not polish the shaft hole. The gap will be large if you polish it, which will affect the service life of the coupling. When installed, the temperature of the shaft sleeve will drop, and the shaft hole will also retract, which will not affect its life.
