How to reduce friction on conveyors with a nosebar (knife ...

Conveyors with one or two nosebars knife edges consume more power than conveyors with bearing pulleys. That’s a given. But we also regularly receive questions about a drive that slips or motors that overheat and turn off. These problems may be caused by friction between the static nosebar and the tensioned belt.

In this paper we study the steady-state rolling contact of a linear viscoelastic layer of finite thickness and a rigid indenter made of a periodic array of equally spaced rigid cylinders. The viscoelastic contact model is derived by means of Green’s function approach which allows solving the contact problem with the sliding velocity as a control parameter.

How to Specify Conveyor Belts | Cisco-Eagle

Jul 07 2020 Belts with less friction should be used for accumulation or sortation where your load needs to move across or slide on the belt while the conveyor is in motion. When you need stability and consistency of placement high friction belting grips the load and allows you to incline or decline the load without fear of box tumbling.
