Section 70.—ANTI-FRICTION BEARINGS.
(See also [p. 152].)
[2402]. Roller bearings for centrifugal milk separators, &c. The pan is carried on three large rollers running against an inverted cone, as shown.
[2403]. Ball bearing for vertical shaft. By Sir Gabriel Stokes.
[2404] & [2405]. Forms of grooves for ball bearings, running horizontally, showing points of bearing in grooves.
[2406]. Roller bearing for a vertical shaft, with steel balls between the ends of the cone rollers to separate them and reduce their friction.
[2407]. Roller bearing for a door, or other article having a limited travel. The roller runs on the floor, or a rail, and its spindle rolls along the slot, the length of which is proportioned to the travel of the door.
[2408]. Double cone rollers for a table having a horizontal circular motion.
[2409]. Roller bearing for wagon axle, with balls between the roller ends to separate them and prevent internal friction.
Anti-friction screws. See Nos. [2413], [2414].
Anti-friction worm gear. See [No. 2451].
[2410]. Vertical ball bearing, with bearing surfaces adjusted to receive the direct thrust of the balls.
[2411]. Suspended ball bearing.
[2412]. Ball or roller axle bearing.
[2413]. White’s anti-friction ball bearing screw and nut. A.D. 1822. Square thread screw, the balls travel round the screw thread, and by a pass-groove back to the other end again.
[2414]. Lieb’s anti-friction screw and nut, similar to the last, but with a concave grooved screw. A.D. 1890.
