Linear actuators convert the rotary motion of motors into linear motion output, possessing good support and load-bearing capabilities, mainly used in high-load scenarios with small motion rotation ...

This system converts rotary motion to linear motion or vice versa. It consists of a circular gear (pinion) meshing with a straight gear (rack), commonly used in steering mechanisms and machine tools.

Adding a leadscrew for rotary-to-linear conversion keeps gearmotor output speed at around 1,000 rpm, which reduces generated heat at the leadscrew and nut-thread interface.

Straight-sided splines have teeth parallel to the axis of linear motion or rotation, whereas the teeth on involute splines are angled, allowing for more gradual engagement between components.

To produce a high speed, load-bearing linear actuator today, many machine and equipment builders invest a good deal of time and money to design a mechanism with rotary-to-linear motion conversion.

April 28, 2016 [2n2r5] posted up a mechanism that we’d never seen before — a threadless ballscrew that turns rotational into linear motion with no backlash.

The transfer of motion through the linkage does not depend on the specific mechanism of electrothermal actuation. Figure 3a directly compares the motion of the translating and rotating links ...
