Effect of Interconnection of the Ends of a Sliding Bearing on Film Thickness.
Abstract
The effect of the area of interconnection between the ends of fast-acting bearings such as those of recoil mechanisms used with American tank guns was studied with an apparatus which simulated a concentric recoil system. It was studied with an apparatus which simulated a concentric recoil system. It was found that these bearings do not starve with a small interconnection area, but a larger area would probably produce a faster-acting bearing. It would also result in a thinner fluid film but this would probably be unimportant. The film thickness continues to increase for a time even after the movement of the recoiling tube has stopped, so there appears little chance that the film would entirely collapse before counter-recoil begins. There are two area ratios that result in thinner film thicknesses and slower formation of the fluid film. These area ratios should be avoided. Their locations were at 1.5 and 4.9 sq. mm but they might be at different locations with the larger actual recoil bearings and with the geometries of specific designs.
