In many devices lead screw assemblies are used to convert motion from rotary to linear and vice versa. Historically these assemblies have had poor efficiencies and relied on grease for improved performance. Over the past few decades the advent of engineered polymers and new manufacturing … [Read more...]
Pressure Velocity and Leadscrew Assemblies
Pressure velocity (PV) is a fundamental property of all plastics, and is specific to the composition of the plastic. PV for a lead screw application is a calculated value based on load and surface speed of the interface between the leadscrew and nut. Manufacturers now have the ability to mold in … [Read more...]
