Through using radial friction instead of sliding friction at the impulse surfaces the coaxial escapement significantly reduces friction, theoretically resulting in longer service intervals and greater accuracy over time.
22.
The Scotch yoke is not used in most internal combustion engines because of the rapid wear of the slot in the yoke caused by sliding friction and high contact pressures.
23.
Any escapement with sliding friction will need lubrication, but as this deteriorates the friction will increase, and, perhaps, insufficient power will be transferred to the timing device.
24.
These compounds are used to reduce the high sliding friction by the helical gear cut of the teeth ( this cut eliminates the characteristic whine of straight cut spur gears ).
25.
In this system the gun-carriage remained stationary, and the recoil of the gun was absorbed by a system of sliding friction blocks attached to the carriage and to the gun.
26.
The former is concerned with static friction, referred colloquially to as " stiction ", or " limiting friction ", whilst the latter is dynamic friction, also called " sliding friction ".
27.
The Swiss lever, although the mainstay in the industry, has the capability to be strong on energy conservation but needs considerable lubrication between the impulse pallet and the escape wheel teeth due to sliding friction.
28.
The contact condition under the shoulder can be described by sliding friction, using a friction coefficient ? and interfacial pressure P, or sticking friction, based on the interfacial shear strength at an appropriate temperature and strain rate.
29.
If the torque applied to one of the drive wheels exceeds the threshold of traction, then that wheel will spin, and thus provide torque only at the other driven wheel equal to the sliding friction at the slipping wheel.
30.
A disadvantage of helical gears is a resultant thrust along the axis of the gear, which must be accommodated by appropriate thrust bearings, and a greater degree of sliding friction between the meshing teeth often addressed with additives in the lubricant.
