| Summary: | Two main factors are considered that determining the
friction between non-lubricated surfaces of an elastomer
and a solid base during their relative motion. The first one
is adhesion in the areas of real (actual) catalysis and the
second factor is the deformation component, which is due to
the delay of recovery of the elastomer after the irregularity
is introduced and it is called the hysteresis component
of friction. One of the main problems of increasing the
resource of pneumatic dampers is minimizing the wear of
the covering layer of the rubber-cord casing (RCC). The
wear of the RCC is due to the fact that sliding friction
occurs in the process of contact between the metal surface
and the surface of the RCC, as a result of which the cover
layer of the RCC (in some cases with the first cord layer)
wears out, depending on the chemical composition of the
rubber and the features of the operation of the pneumatic
shock absorber. In order to minimize the wear of rubber, it
is proposed to change the design of the pneumatic damper
so that rolling friction dominates in the contact between
the surfaces of rubber and metal. |
