Revised Chain and Escalator Step Chain,Comprising a plurality of
link units interconnected in series with each other, each of the link
units comprising pairs of inner links in parallel with each other,
arranged in pairs and in parallel with each other for connecting two
adjacent link units And a steel wheel rotatably provided on
the steel wheel shaft, characterized in that the link unit further
comprises a traction main wheel, the traction main The
wheel is provided on the steel wheel shaft and the outer diameter of the
traction main wheel is larger than the outer diameter of the steel
wheel. Since the outer diameter of the traction
main wheel is larger than that of the steel wheel, the steel wheel plays
a supporting role when the cascade Chain is driven by the drive steel
wheel, and the main wheel takes the active action, so that the violent
friction between the steel wheel and the transmission wheel can be
avoided , Significantly extending the service life
of the steel wheel and effectively protecting the transmission wheel,
and the noise in the cascade chain movement is significantly reduced. Chain Escalator Chain, Lift Chains, Escalator Chain Design,Revised Chain,Escalator Step Chain Realever Enterprise Limited , https://www.cnelevator-parts.com
