Coupling

Information
Couplings are divided into two categories: flexible couplings and rigid couplings
When it is difficult to arrange the two axes of power transmission in a straight line, or when the installation of the two axes is very simple, a flexible coupling should be used, which has the functions of mitigating impact, absorbing parallelism, deflection, axial misalignment, and improving system transmission. The function of dynamic characteristics, so during installation, even if the shaft has a slight deviation, the bearing will not be forced. It is widely used in the market. Rigid coupling is a component that cannot cause eccentricity and declination, and can The two connected axes are fixed into one body.

Stop screw fixed type
Four fixing screws are fixed on the axis at an angle of 120° or 90°. It is easy to design. There are easy screw indentations on the surface of the axis. It is easy for the screws to loosen due to long-term rotation and impact of the machine. It saves space and has a low unit price. Cheap. |
Clamping
There are grooves cut on both sides of the coupling to form an elastic effect, and two or four head hexagonal screws are inserted on both sides of the clamping shaft for easy disassembly without damaging the axis, and have better stability and retention. |
