Abstract: 764,609. Bearings. BRITISH THOMSONHOUSTON CO., Ltd. June 22, 1955 [July 9, 1954], No. 20185/54. Class 12 (1). In the transport of machinery having a rotary member mounted in bearings, such as a dynamo - electric machine, the vibrations imposed thereon are utilized to effect a rotation of the said rotary member to prevent damage to the bearings thereof. The stator 3 of the machine is secured to the base 1 of a packing case or floor of a transporting vehicle through resilient pads 2 so that it will move in response to vibration. A flexible belt, wire, string, tape, rope or cord 5 is secured at point A to the base 1, passes around the shaft 6 of the rotor 4 and is secured again at B to the base 1 through the intermediary of a spring 7. Thus, the movements of the stator 3 effects a frictional drive on to the shaft 6. Alternatively, the stator 3 may be rigidly fixed to the base 1 and the end of the flexible member 5 opposite to the spring 7 may be attached to a mass which is resiliently supported on the base 1. In this case vibrations effect movements of this mass which are transmitted by the flexible member 5 to the shaft. The member 5 may engage any coaxial cylindrical surface other than the shaft 6 itself.
