Abstract
The rotary motion created by a motor is transmitted from the drive shaft of the motor to the driven shaft through a pair of diametrically opposed balls fitted into a coupling mechanism attached to the drive shaft and through a pin fitted into holes formed in the opposed balls and through the driven shaft disposed between the opposed balls for eliminating vibration and noise. The thrust loads imposed in the structure supporting the motor is directed to bypass the motor through a bearing supporting the driven shaft through its housing and into the outer housing surrounding the motor. The motor is encased in a cartridge disposed in a central cavity of the outer housing and the cartridge is not rigidly attached to the outer housing so that the thrust loads bypass the motor.
