THERMAL STABILITY OF CROSSED HELICAL GEARS WITH WHEELS MADE FROM SINTERED STEEL

Abstract

A considerable slide exists between the flanks of worm and gear during the work, hich results in flank wear and considerable loss of energy. The energy is, hereby, converted into heat, which leads to the warming-up of gear drive, ompromising its correct operation, and to scuffing in critical cases. Oil emperature has an important role in thermal stability. Viscosity depends on emperature. Viscosity significantly affects the processes in the contact zone, i.e. he energy losses, and hence the temperature. Optimal lubrication can be rovided only in the relevant field of temperatures. The paper presents xperimental and theoretical research on the effect of temperatures and thermal tability of a worm and gear set with a gear made of sintered steel Fe1.5Cr0.2Mo n their ability and appearance of boundary conditions.
