Design and modelling of CRB cutting equipment for batch processing

open access: yesThe Journal of Engineering, 2018
Ceramic roller is more reliable than metal roller. However, ceramic materials are difficult to process due to their high hardness and great brittleness. They are easy to crack and easy to damage cutting tools. To batch processing of ceramic roller blanks

SYNTHESIS OF DOUBLE-LOBED CAM MECHANISMS WITH TRANSLATING DOUBLE - ROLLER FOLLOWER

open access: yesInternational Conference on Technics, Technologies and Education, 2018
Two rational mathematical models for synthesis of mechanisms with conjugate disk cams translating with offset roller follower are derived from the equivalent four-bar linkage theory. They are linear and comparable in their relative simplicity, applicability and principle accuracy. The re-sults obtained from one model are verified by another, so any

Simulation of a freight wagon bogie in double roller test rig

open access: yesAdvances in Mechanical Engineering
Test benches are useful tools for testing bogies in laboratory conditions, most of which consist of large rollers to move the wheels of the bogies, either at a reduced scale or at full size. The full-scale test rig located at the BOGLAB laboratory uses two small rollers to move each wheel of one of the bogie’s wheelsets.
