Classification of rigid couplings:

Rigid couplings are divided into two kinds: shell type and sleeve type. Products are available in a variety of sizes with equal diameter and stepped aperture couplings. At the same time, we can also supply one end of the British and the other end of the metric coupling according to customer's special request.

The types of rigid coupling are introduced:

Sleeve coupling is also called integral rigid coupling, tightly set on the shaft can torque grip, compared with the screw type rigid coupling, it will not cause shaft damage and vibration wear. Clamp shell coupling, sometimes known as two clamping type rigid coupling or double groove coupling, in addition to the advantages of sleeve type rigid coupling, it also has the characteristics of easy disassembly and maintenance, and do not need to move other parts. Clamp shell type rigid coupling screw is reverse symmetrical installation, can _ good dynamic balance performance.

Compact rigid couplings, in narrow places, a widened shape of the shaft sleeve to replace the choice of rigid couplings, can be used as compact rigid couplings. Compared to rigid couplings, the torque transfer capacity of the widened type bushing is reduced because each connecting shaft is locked by a single hexagon head screw. But the compact structure of the widened bushing reduces its inertia, so it is an ideal choice for motion control applications.

To sum up:

Rigid coupling has many advantages such as better economy, large transfer torque and zero back backlash. Rigid coupling for shaft alignment deviation has very strict requirements, can be connected to the alignment of the shaft, or connected to the motor and reduction box. Rigid coupling is widely used in motion control applications of precise installation of parts.
