An Investigation of the Performance of Waste-Packed Armature Bearings

G. B. Karelitz


Some of the observations made while experimenting with full-size armature bearings are recorded in this paper. The importance of taking care in the packing of bearings is brought forth. The advantages of a constant oil lift are pointed out, while the effect of grooving is discussed. Bearing-shell temperatures for varying loads and speeds are given. The data collected may be of interest to designers as well as to engineers in charge of maintenance of railway motors.
