Temperature in a Rotating Ring Subject to Frictional Heating from Two Stationary Pins

Abstract

The purpose of this article is to establish a partitioning heat ratio between two stationary cylindrical pins and a rotating ring. The mixed quasi-stationary heat conduction problem for the ring is solved. The fast-moving heating on the external surface of the ring due to two rotating locally distributed heat flows is considered. The heat conduction from the sliding contact zones in the axial direction of the ring, as well as the heat convection from the sides, external, and internal surfaces of the ring are taken into account. The solution of this problem is obtained by using a finite Fourier transformation. The solution of the steady heat conduction problem for the semi-infinite pins which are heated up at end faces taking account of cooling from lateral sides is known. By matching the average temperatures of the ring and the pins in the contact regions, the coefficients of the heat distribution between them is found. The influence of the circumferential distance between the pins and the ratio of the intensities of the frictional heat flows on the surface temperature is studied.

The influence of distribution intensity form of heat flux on the temperature by the local quasi-stationary heating on external surface of the ring

“…They are frequently encountered in such manufacturing processes as metal cutting, grinding, polishing, welding, as well as in many tribological applications, such as bearings, meshing of gears, asperities in sliding contact. The examples were described in papers [3,8].…”

Influence of convective cooling on the temperature in a frictionally heated strip and foundation

“…In such statement the problems of transient frictional heating in cold rolling of metals [19], the heat transfer in friction welding of cylindrical rods with different diameters [20] and the fast-moving heating on the external surface of the ring due to friction of two rotating pins [21] were analyzed. The analytical solution of a boundary-value problem of heat conduction for tribosystem, consisting of the homogeneous semi-space, sliding uniformly on a surface of the strip deposited on a semi-infinite substrate, was obtained in paper [22].…”
