Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1909 edition. Excerpt: ... to make a half circle in the bearing are used, and these are spaced apart by means of small helical springs. These springs contain oil pads of felt, and are headed by sheet-metal discs that extend far enough into the grooves to prevent sidewise displacement of the springs, without, however, producing any more than a negligible friction. Assembling this bearing one race is placed eccentric to another race and the requisite number of balls slipped into positions, after which the races are made concentric and the balls regularly distributed. This done, the separating springs with lubricating means are installed. Once the springs are in place the tension of them is such as to make the bearing selfcontained. In different types of annular ball bearings different methods of separation are used. In one type shown in Fig. 9, 92 per cent of the annular space between the races B and C is occupied by the balls, a particularly valuable feature of the bearings. It is possible to get this number of balls between the races B and C by means of entering spaces D, in one side of the races: the balls are separated by spacers E, which anchor to rings F. Each spacer E has its sides grooved to accommodate the balls. In another type of annular ball bearing the balls are carried between concentric races, and are located directly in a special carrier made in halves, which halves are anchored together by brass wires of dove-tail section which are inserted in dove-tail grooves and have their ends clutched over into notches in the sides of the separators. The latest type of Hess-Bright bearing is made without the spring referred to in Fig. 8, and has the balls retained by separators. These separators are positioned after the balls are fitted, and permit of carrying a...show more
