RESEARCH OF THE OPERATION OF MAGNETIC BRAKE ROLLERS OF GRAVITY ROLLER CONVEYORS

Fundamental and Applied Problems of Engineering and Technology, 2021
One of the main elements of safe operation of gravity conveyors used in gravity racks for pallets is the brake roller. The most promising design is a brake roller of magnetic (eddy current) type. A mathematical model of the process of moving pallets on a magnetic brake roller is developed.

Enhancing the Roller Brake Tester

SAE Technical Paper Series, 1992
<div class="htmlview paragraph">Enhancements have been developed for low speed roller brake testers that make them more useful devices for testing and diagnosing braking systems. The enhancements are primarily designed for the evaluation of air brake systems but have application to hydraulic brake systems as well.</div>

Understanding the Portable Roller Brake Dynamometer

SAE Technical Paper Series, 1998
<div class="htmlview paragraph">Of the several types of performance-based brake testers (PBBTs), roller dynamometers (RDs) have been used for more than 20 years in Europe to judge the braking capabilities of commercial vehicles and for enforcement of minimum brake performance requirements.

Study on Double-Drum Roller Maximum Braking Deceleration

Applied Mechanics and Materials, 2011
Reducing start and stop time is important in enhancing productivity of double roller and compact quality of asphalt pavement, but it is difficult in confirming the max braking deceleration or starting acceleration of double-drum roller. Dynamic analysis is used and a mathematic model of double roller is established.

Selection of Materials of Friction Lining Centrifugal Brake Rollers

Journal of Friction and Wear, 2019
Abstract—The results of friction-wear tests of rolled friction-polymer materials (FPM) of two types using the operating modes of the friction brake of a centrifugal type roller are presented in this work. The tests were performed on the Nanovea T50 tribometer according to the pin-on-disk scheme.

A Calibration Instrument for Roller Brake Testers

1986
In the Netherlands, since September 1985 a statutory obligation exists for an annual examination of motor verhicles. Resulting from the Act a number of metrological activities with respect to the measuring instruments in use at the test stations are carried out by the Nether-lands Metrology Service, i.e.
