An acme or trapezoidal screw, which hereafter will be addressed as lead screw, consists of a screw and a nut that are in sliding contact
with each other.
Tribological behavior of metals which are in sliding contact
depends on the many variables such as normal load applied on the material, sliding speed, sliding distance, surface geometry, surface hardness, roughness of operating surface, working environment, etc.
On the other hand, the rotors in the conical screw compressor are in continuous rolling and sliding contact
, and friction can present a challenge.
A lab-scale test (ball-on-pyramid) was used for fundamental studies into a lubricated steel to plastic sliding contact
Earthing Connection by means a sliding contact
, suitable for 31,5kA 3 sec.
The wear of the sliding contact
materials contributes to warming, to dissipate the energy of friction between the two materials.
The non-contacting sensing technology also facilitates clean, ratiometric absolute position outputs across multiple turns without sliding contact
fix]; when sliding embedding occurs, there exists a sliding contact
potential energy function [[PI].
In this study, a measure of damage was defined as the Coulomb friction coefficient; that is, a nondamaged state is associated with the friction coefficient at the steady-state sliding contact
after the running-in period.
The samples, which revealed abrasive wear and/or oxidational wear in sliding contact
, based on the analysis of counter surfaces, resulted in much lower wear rate and initially also lower CoFs.
7] have studied the tribological behavior of nanoporous structure films with various pore sizes in sliding contact
with steel ball, varying the normal load from 1 mN to 1N.
A surface-to-surface, finite sliding contact
definition was used to optimize the stress field calculation due to bodies in contact .
