An innovative dynamic model for vibration analysis of a flexible roller bearing
Mechanism and Machine Theory, 2019Due to the centrifugal forces and external loads, the components of a cylindrical roller bearing (CRB) will produce elastic deformations, which will significantly influence the bearing vibrations.

Magnetic bearing conveyor roller : Clean room roller
2019This project is covering the development of a magnetically suspended belt conveyor system that would be able to operate in high-end cleanroom environments. The design would have sets of rollers held in place by permanent magnets so that it would levitate in mid-air. Thus, eliminating friction produced from conventional roller designs.

Roller Skewing Behavior in Roller Bearings
Journal of Lubrication Technology, 1982Measurements of roller skewing of a 1.15 length to diameter ratio roller in 118 mm bore roller bearings of 0.18 and 0.21 mm (0.0073 and 0.0083 in.) clearance operating with a 4450 N (1000 lb) radial load at shaft speeds of 4000, 8000, and 12,000 rpm with outer race misalignment of 0, 0.5, and −0.5 deg are reported.

Collaborative operation and real-time control of roller fleet for asphalt pavement compaction
Automation in Construction, 2019Compaction is one of the most critical processes in the asphalt pavement construction. Collaborative control of multiple rollers in the construction site to enable each roller to compact the right position at the right time with the right compaction ...

Modelling of static contact with friction of threaded surfaces in a planetary roller screw mechanism
Mechanism and Machine Theory, 2019This paper investigates the nature of the contact with friction between the threaded surfaces in a planetary roller screw mechanism (PRSM). Contact analyses are applied to both the screw/roller interface and roller/nut interface. Prior work has neglected

MODERNIZATION OF CUSHIONING DEVICES OF ROLLERS ROLLERS
Наука та виробництво, 2022У даній статті викладені варіанти підвищення довговічності підшипників кочення за рахунок поліпшення розподілу контактних напружень. Аналіз роботи великих підшипників кочення роликів рольганга стану 3000 показав, що однією з причин виходу їх з ладу є високий рівень паразитних навантажень.
