Abstract of the Disclosure
A unit bearing motor has a bearing assembly mounted
on the shaft of the motor on one side only of the rotor.
The bearing assembly includes spaced-apart spherical bear-
ings rotatably mounted on the shaft, spring retainers
mounted in facing relationship to each other on the sides
of the bearings that are adjacent to each other, a com-
pression spring positioned between the spring retainers
and urging the bearings away from each other, and bearing
seats against which the bearings are urged by the spring.
One of the bearing seats is formed in a cup-shaped wall
of a casing of the motor which is mounted on one side of
the stator of the motor. This cup-shaped wall defines
an open-ended cavity in which the bearing assembly is
located. The other bearing seat is formed on a closure
member that closes the open end of the cavity, the latter
containing suitable material for retaining oil to lubricate
the bearings. The cup-shaped wall includes a rim surround-
ing the closure member, the rim being rolled over or
swaged over the closure member to hold it in place.
