Abstract
Abstract The disclosed clamping plate exhibits a particularly great spring action and it includes a clamping rim (10) and with spring tabs (20) which point radially inward and against which the cups of the self-aligning or cup-type bearing make contact. According to the invention the spring tabs (20) are particularly long and extend from the clamping rim (10). The tabs also bend inwardly over a bead (9) limiting the clamping rim (10). An especially inexpensive design from the aspect of production engineering and assembly is achieved in that the transition from the bead (9) to the plug-in hole (2) is rounded in the plug-in direction (6) of the clamping plate and the lower area of the bead (9) is designed as oil collecting groove.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
81 words
A clamping plate for retaining self-aligning friction bearings in an electric motor, comprising: a circular body with a central seating hole and a clamping rim formed on said body, said circular body having a larger diameter than said seating hole; spring tabs connected to said rim and pointing radially inward and being offset in a direction opposite to a predetermined plug-in direction of the body; and said clamping rim having a limiting bead over which said spring tabs are inwardly bent.
Claim 2
Dependent Claim
81 words
A clamping plate for retaining self-aligning friction bearings in an electric motor, comprising: a circular body with a central seating hole and a clamping rim formed on said body, said circular body having a larger diameter than said seating hole; spring tabs connected to said rim and pointing radially inward and being offset in a direction opposite to a predetermined plug-in direction of the body; and said clamping rim having a limiting bead over which said spring tabs are inwardly bent.
Claim 3
Dependent Claim
41 words
The clamping plate according to claim 1, wherein the central hole is adapted to the diameter of the self-aligning friction bearing and the inside diameter of the spring tabs in their relaxed position is smaller than that of the central hole.
Claim 4
Dependent Claim
28 words
The clamping plate according to claim 1 wherein said body includes a transition from said bead to said central hole which transition is rounded in the plug-in direction.
Claim 5
Dependent Claim
20 words
The clamping plate according to claim 1 wherein said bead has a lower area to form an oil collecting groove.
Claim 6
Dependent Claim
34 words
A clamping plate according to claim 4, wherein said spring tabs have free ends which are approximately parallel to the bead and are oriented towards the central hole, the bead having a rounded transition.
Claim 7
Dependent Claim
98 words
A clamping plate for retaining self-aligning friction bearings in an electric motor, comprising: a circular body with a central seating hole and a clamping rim formed on said body, said circular body having a larger diameter than said seating hole; spring tabs connected to said rim and pointing radially inward and being offset in a direction opposite to a predetermined plug-in direction of the body; and said clamping rim having a limiting bead over which said spring tabs are inwardly bent, the limiting bead being cut out on both sides of the bend to turn said spring tabs.
Claim 8
Dependent Claim
98 words
A clamping plate for retaining self-aligning friction bearings in an electric motor, comprising: a circular body with a central seating hole and a clamping rim formed on said body, said circular body having a larger diameter than said seating hole; spring tabs connected to said rim and pointing radially inward and being offset in a direction opposite to a predetermined plug-in direction of the body; and said clamping rim having a limiting bead over which said spring tabs are inwardly bent, the limiting bead being cut out on both sides of the bend to turn said spring tabs.
