Principles of taper sleeve connection technology
Taper sleeve connection technology uses the taper principle to fasten parts to the shaft. Its essence is to convert axial force into radial force. To make this structure able to produce Maximum fixing force, but at the same time, it can make the parts easy to separate. Just make the taper lock taper sleeve take the best taper angle (
) to achieve the goal.

Among the taper sleeve matching systems, the most commonly used and well-known are the
(International) and
(Morse) systems. The former has a taper angle of The diameter change along the length is
inches, the taper angle is

, there is no self-locking ability, and the matched parts are easy to separate without mechanical force constraints. Typical
Taper Use For securing drills and reamers to machine tool holders, the taper is
inches per foot of length and the taper angle is

, even with lubrication. This taper also maintains self-locking capabilities.

Comparison between taper sleeve connection and key connection

In traditional applications for many years, the assembly method of using key fitting to install power transmission components on the shaft is time-consuming and expensive. Because it requires the hub inner hole and shaft diameter to maintain high-precision dimensions and tolerances. This traditional method is also used in low-power transmission devices. For light-load transmissions, the cost of key couplings is more expensive. The advantage of the taper sleeve connection relative to the key connection is that it is easy to disassemble and assemble. During installation, you only need to place the hub and shaft in the relative position of the connection, put in the taper sleeve, and then tighten the two screws according to the regulations. Since the inner hole of the taper sleeve shrinks to a certain amount when connecting, the tolerance range of the shaft is larger, so the processing cost of the shaft can be reduced, and its fit is equivalent to a shrink fit, which can evenly distribute the load. Using a series of taper sleeves with the same outer diameter but different inner hole diameters can realize the connection between the hub and shafts of different diameters. This feature makes the taper sleeve very suitable for the connection between the same coupling and different shafts.
