When the output disk is adjusted to a position equal to its own radius, the resulting drive ratio is 1:1. The drive ratio can be set to infinity (i.e. a stationary output disk) by moving the output disk to the center of the input disk. The output direction can also be reversed by moving the output disk past the center of the input disk.
The clutch consisted of a wrap-spring clutch-brake that was coupled to the rotor by one or two stages of reduction gearing. The clutch-brake locked up when rotated backwards, but also had some spring action. The inertia of the rotor going backwards engaged the clutch and wound the spring. As it unwound, it restarted the motor in the correct ...
Aside from the belt/chain itself, also common is a failure of the tensioner, and/or the various gear and idler bearings, causing the belt/chain to derail. Furthermore, in engines where the timing belt drives the water pump, failure of the water pump can cause the pump to seize, which can break the timing belt or chain.
One-way bearing combining sprags and bearing rollers in one race Sprags jam when driven and slide when in reverse. A sprag clutch is a one-way freewheel clutch.It resembles a roller bearing but, instead of cylindrical rollers, non-revolving asymmetric figure-eight shaped sprags, or other elements allowing single direction rotation, are used.
It was the replacement for the DC17. Has a powered cam to adjust the height of the brushbar ("Dyson Airmuscle") controlled from a set of buttons by the main power switch above the cyclone assembly, a pneumatic actuator to keep the cleaning head on the floor, and a high-torque clutch to give extra power to the brushbar.

The compact Comet shared a naming convention associated with the ongoing Space Race of the early 1960s with the Mercury Meteor, which was introduced as the base-trim full-size Mercury sedan. The Comet was initially based on the compact Ford Falcon, then on the intermediate Ford Fairlane, and finally on the compact Ford Maverick. Early Comets ...
With the clutch off, so the shaft does not spin, the idlers in the two differentials are fixed in place. This is just like the controlled differential with the brake on. When the steering clutch is engaged, the shaft spins one of the idler sets forward and the other backward, causing one track to speed up and the other to slow down. [2]
1963 Leyland Comet (LAD) In 1958, as part of an effectivization program, the Comet received a new cab – called the "Vista Vue" cab, it was developed by Albion for a variety of their models. Dodge UK also used it for their 300 model, consequently this cabin shape is often referred to as the "LAD" design. There was also a heavier duty "Super ...
