Abstract:
In an apparatus that performs a desired operational function in response to a rotating drive shaft member wherein motor means includes a rotatable power input shaft means for rotating the drive shaft member, and motor control means regulates the rotational speed of the power input shaft means, a power transmission combination comprising:a) driven output shaft means coupled to rotate said drive shaft member,b) flywheel means mounted to rotate on shaft means other than said driven output shaft means and about a flywheel axis of rotation; andc) gear train means connected to rotate with the power input shaft means for rotating the flywheel means about said flywheel axis of rotation and for rotating said driven output shaft means when the motor means rotates the power input shaft means;d) said gear train means being effective to rotate the flywheel means when a load is applied to the driven output shaft means so that the motor means continues to operate smoothly without being adversely affected when the motor control means increases the rotational speed of the power input shaft means for rotating the driven output shaft means through the gear train means under an increased applied load.
