Constant speed couplings improve registration and system accuracy when machine function requires driven shaft offsets. Using Schmidt Offset Couplings from Zero-Max, these couplings provide machine designers with a proven method to ensure constant speed at both ends of the coupling connection and accurate machine registration. Where precision alignment of system components is required and reduced […]

How do you calculate the angle of twist on a line shaft?
By Zak Khan The angle of twist on a line shaft involves its geometry, and the torque applied to it. Engineers use this calculation to determine the rotational displacement of a shaft given a certain load. The angle of twist calculations also involve determining the second area moment of inertia of a shaft. Engineers usually […]
How does spring stiffness affect couplings selection?
By Zak Khan Spring stiffness affects couplings in a few ways. Because many couplings act as springs or use the concepts behind springs in their construction and operation, spring stiffness affects their selection. When a coupling experiences a load in a direction that places it in tension or compression, its spring stiffness comes into effect. […]
How do you select a coupling when you expect heavy and percussive loads?
By Zak Khan When engineers are selecting couplings for heavy and percussive loads, there are a few design considerations to keep in mind. These include the type of coupling, the operating conditions and the spacing of the various couplings and shafts. When considering the ends of couplings, the end that carries the load or otherwise […]
What is a flange connection?
What is a flange connection? A flange is a protruding ring, collar or lip at the end of a shaft, pipe or other mechanical component. These rings or collars help add strength, stiffness and stability to connections. In the case of couplings, this non-positive connection of screws inserted through a pitch circle leads to fast […]
