Abstract

A self-aligning bearing 1 has a passage 2 in a central cylindrical portion 3 to receive an end of a shaft 4 of a motor, which includes a stator 5. The bearing 1 has fingers 6 extending from a radial portion 7 for cooperation with a shoulder 8 of the stator 5 to hold the bearing 1 in the position shown in Fig. 1. Another self-aligning bearing 9 is shown in Fig. 2. The bearing 9 has a thicker radial portion 10 than the radial portion 7 (Fig. 1) of the bearing 1 except for a reduced annular portion 11 (Fig. 2). The bearing 9 also has fingers 12 for cooperating with the shoulder 8 of the stator 5. The relatively thin radial portion 7 of the bearing 1 provides more self-aligning to enable the axis of the bearing 1 to pivot freely until it is parallel with the axis of the shaft 4. This flexing of the bearing 1 is shown in Fig. 3.

Self-Aligning Bearing

A self-aligning bearing 1 has a passage 2 in a central cylindrical portion 3 to receive an end of a shaft 4 of a motor, which includes a stator 5. The bearing 1 has fingers 6 extending from a radial portion 7 for cooperation with a shoulder 8 of the stator 5 to hold the bearing 1 in the position shown in Fig. 1. Another self- aligning bearing 9 is shown in Fig. 2. The bearing 9 has a thicker radial portion 10 than the radial portion 7 (Fig. 1) of the bearing 1 except for a reduced annular portion 11 (Fig. 2). The bearing 9 also has fingers 12 for cooperating with the shoulder 8 of the stator 5. The relatively thin radial portion 7 of the bearing 1 provides more self-aligning to enable the axis of the bearing 1 to pivot freely until it is parallel with the axis of the shaft 4. This flexing of the bearing 1 is shown in Fig. 3. The bearing 9 (Fig. 2) has less self- aligning capacity than the bearing 1 (Fig. 1) but more radial support. Each of the bearings 1 and 9 functions as a radial load bearing and a thrust bearing. Additionally, if desired, a dust cover 13 can be formed on the end of either of the bearings 1 and 9, as shown in Fig. 4 for the bearing 1.
