In mechanical engineering, a jaw coupling is a type of general purpose power transmission coupling that also can be used in motion control (servo) applications. It is designed to transmit torque (by connecting two shafts ) while damping system vibrations and accommodating misalignment, which protects other components from damage.
For example, if there are 202 teeth on the circular spline and 200 on the flex spline, the reduction ratio is (200 − 202)/200 = −0.01 Thus the flex spline spins at 1/100 the speed of the wave generator plug and in the opposite direction. Different reduction ratios are set by changing the number of teeth.
Some diver propulsion vehicles and remotely operated underwater vehicles use magnetic couplings to transfer torque from the electric motor to the prop. Magnetic gearing is also being explored for use in utility-scale wind turbines as a means of enhancing reliability. [1] The magnetic coupling has several advantages over a traditional stuffing ...
A coupler connecting a crank and a slider in a single slider crank mechanism is often called a connecting rod, however, it has also been used to refer to any type of coupler. There are three basic types of planar four-bar linkage, depending on the use of revolute or prismatic joints:
A spline is a ridge or tooth [1] [2] [3] on a drive shaft that matches with a groove in a mating piece and transfers torque to it, maintaining the angular correspondence between them. For instance, a gear mounted on a shaft might use a male spline on the shaft that matches the female spline on the gear.
In mechanical engineering, backlash, sometimes called lash, play, or slop, is a clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence."
The Johnston coupler, commonly known as a bell link-and-pin coupler from its bell shape, was first introduced in the Cape of Good Hope in 1873, following the establishment of the Cape Government Railways (CGR) in 1872 and the decision by the Cape government to expand the railways into the interior and to convert the existing tracks from 4 ft 8 ...
This consisted of a stainless steel clip (of size approximately 6 mm long and 1.2 mm wide at the prongs) with a metal deployment device (that could be used to insert the clip into the endoscopic camera, and deployed outside the camera) enclosed in a plastic sheath. [1] These clips were initially reloadable. [citation needed] Endoclips in use ...
