Abstract
Abstract A unitarily constructed mounting element which inhibits the transmission of vibrations from a small electric motor to the device or instrument to which the motor is attached. The element includes at least two zones having differing energy loss factors. One of the zones provides damping to prevent the transmission of high-frequency radial vibrations, while another of the zones serves as insulation to prevent the transmission of low-frequency tangential vibrations.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
In a vibration-inhibiting element for use in mounting a small electric motor to a motor-driven device by means of a shaft coupling, the improvement comprising: a single unitarily constructed element having at least two zones of differing energy loss factors, one of said zones having an energy loss factor such that the relatively high frequency radial sound vibrations of the motor are dampened and thus prevented from being transmitted to the device and another of said zones having an energy loss factor such that the relatively low frequency tangential vibrations of the motor are insulated from and thus prevented from reaching the device; said one zone of said element being the central portion thereof which is shaped to support a ball bearing for the electric motor shaft; said other zone including at least one side member extending laterally from said one zone and secured thereto, each of said side members having at least one opening therein for receiving a member projecting from the bearing plate of the motor in a direction substantially parallel to the shaft thereof.
Claim 2
Dependent Claim
177 words
In a vibration-inhibiting element for use in mounting a small electric motor to a motor-driven device by means of a shaft coupling, the improvement comprising: a single unitarily constructed element having at least two zones of differing energy loss factors, one of said zones having an energy loss factor such that the relatively high frequency radial sound vibrations of the motor are dampened and thus prevented from being transmitted to the device and another of said zones having an energy loss factor such that the relatively low frequency tangential vibrations of the motor are insulated from and thus prevented from reaching the device; said one zone of said element being the central portion thereof which is shaped to support a ball bearing for the electric motor shaft; said other zone including at least one side member extending laterally from said one zone and secured thereto, each of said side members having at least one opening therein for receiving a member projecting from the bearing plate of the motor in a direction substantially parallel to the shaft thereof.
Claim 3
Dependent Claim
18 words
The improvement defined in claim 1 wherein said zones of said element are made of the same material.
Claim 4
Dependent Claim
24 words
The improvement defined in claim 2 wherein the differing energy loss factors of said zones result from different degrees of prestressing of said material.
Claim 5
Dependent Claim
24 words
The improvement defined in claim 2 wherein the differing energy loss factors of said zones result from a differing form elasticity of saiD material.
Claim 6
Dependent Claim
32 words
The improvement defined in claim 1 wherein each of said zones of said element is made of a piece of a different material having a different elasticity, said pieces being secured together.
Claim 7
Dependent Claim
51 words
The improvement defined in claim 1 wherein said one zone is circular in shape, said improvement further comprising bracket means for holding said element, said bracket means having a disc-shaped indentation for supporting said one zone and at least one frame attached thereto for supporting said side members of said element.
Claim 8
Dependent Claim
34 words
The improvement defined in claim 1 wherein said side members include at least one lateral protrusion means, extending into said at least one opening, for holding the respective received one of said projecting members.
