Abstract

The present invention provides a motor mounting arrangement adapted to absorb motor torque vibration and impulses of an electric motor. The mounting arrangement converts the torque vibrations of the motor into controlled rotational movement caused by motor torque vibration while maintaining axial integrity of the motor shaft.

Claims

1. A mounting arrangement for supporting a motor in a wall member comprising:

a. an electric motor having a rotatable shaft disposed in a substantially horizontal position and extending through a passageway in said wall member, and

1. a plurality of support elements on said motor extending parallel to and spaced equidistance from said shaft,

2. said support elements extending substantially centrally through aligned openings of equal number and spacing in said wall member;

b. a mounting member including a body portion having a collar projecting from said body portion arranged circumferentially around said shaft,

1. said collar being disposed in said passageway, and of a dimension to permit rotational movement of said mounting member relative to said wall member,

2. a plurality of sleeve means of equal number and spacing as said aligned openings projecting from said body portion through each said aligned opening of said wall into intimate contact with an opposing surface, and

3. said sleeve means having centrally located holes extending longitudinally therethrough for receiving said support elements, and

4. means arranged on said support elements for securing said mounting member against said motor with said wall member arranged between said motor and said mounting member;

c. retaining means being positioned so that said motor and mounting members are prevented from moving axially relative to said wall member; and

d. resilient means arranged between said sleeve means and their respective aligned openings for absorbing rotational motor torque vibration.

2. A mounting arrangement as recited in claim 1 wherein the retaining means comprises:

a plate mounted on said motor so that said support wall is arranged between said plate and said mounting member, said opposing surface that said sleeve means is in intimate contact with being said plate.

3. A mounting arrangement as recited in claim 1 wherein the retaining means comprises:

a plate mounted on said wall member and being spaced therefrom so that said mounting member is arranged between said plate and said wall member, said opposing surface that said sleeve means is in intimate contact with being said motor.
