Split Flange Bushing

The taper sleeve is a very common mechanical transmission connector. The taper sleeve can be widely used in conjunction with belt pulley, sprocket, gear and other parts and shafts. The taper sleeve can bring high centering accuracy, compact structure, convenient installation and other advantages to the transmission components. At present, the common taper sleeves are divided into two types: transmission taper sleeves and structural taper sleeves. What are the main differences between the two types?

There are two types of taper sleeves:

1. Taper sleeve of transmission part: its taper is generally greater than 1:20, and it is widely used in transmission structures, such as gears, belt pulleys, sprockets, synchronous belt pulleys, etc. It often needs to be disassembled in practical applications, such as installing and replacing gears.

2. Taper sleeve of structural member（split flange bushing）: the taper is generally not greater than 1:20, which is used in structures with high centering accuracy requirements and generally do not need to be disassembled in use. The taper sleeve of structural part refers to the taper sleeve in the structure that is not directly used for belt transmission, chain transmission and gear transmission, but also transmits power.

QD taper sleeve products adopt ANSI standard. After chemical treatment, the cone sleeve(split flange bushing) is covered with a layer of dense anti-corrosion material, and each specification has a series of standard metric and imperial pore sizes. Provide hexagon bolts and shallow keys. Packed separately. QD cone sleeve is made of nodular cast iron with high strength and moderate hardness, and H cone sleeve is made of C45.  

American Standard QD taper sleeve(split flange bushing) is different from TB taper sleeve. It is equipped with flange and locked at the end face, which has greater load bearing capacity and can also meet greater torque radial impact. 

Like TB cone sleeve, it also has excellent ability of fast assembly and folding and time-saving and efficient. 

At the same time, it can also meet and make up for the precision of shaft or shaft tolerance, and the close transmission fit can be

It is one of the superior and optimal schemes in modern mechanical design.
