Continuously variable transmission with a select revolutions per minute output

A power delivery system comprising:

• a motor configured to generate engine torque;
• a continuously variable transmission (CVT) with a constant revolutions per minute (RPM) output including,
• an input clutch in operational communication with the motor to receive the engine torque generated by the motor, the input clutch including one of a torque sensitive actuator and an RPM sensitive actuator to set a gear ratio of the input clutch,
• an endlessly looped member, and
• an output clutch in operational communication with the input clutch via the endlessly looped member, the output clutch including, output post,
• an output fixed sheave axially fixed on the output post,
• an output movable sheave axially slidable on the output post, and
• an output actuator configured to move the output movable sheave in relation to the fixed sheave on the output post in response to a change in at least one of an input torque and an input RPM that is delivered to the output clutch via the endless looped member to maintain a constant RPM output of the output clutch at a select RPM,
• a plurality of ramps, each ramp having a select slope;
• a roller for each ramp, each roller positioned to engage an associated ramp, wherein one of each roller having a select mass and the slope of each ramp selected to maintain the constant RPM output of the output clutch at the select RPM in response to at least one of torque inputs within a torque input range and RPM inputs within an RPM input range delivered to the output clutch;
• and
• a rotational input operated device in operational communication to receive the constant RPM output of the output clutch at the select RPM.

A method of calibrating an output clutch of a continuously variable transmission (CVT) to produce a constant revolutions per minute (RPM) output at a select RPM for inputs in an input range, the method comprising:

• applying at least one of torque inputs and RPM inputs across the input range to an output clutch of the CVT;
• monitoring an RPM output of the output clutch throughout the input range of the at least one of the torque inputs and the RPM inputs;
• and
• when the monitored RPM output of the output clutch does not provide a desired constant RPM output at the select RPM throughout the input range, switching at least one of current rollers used to move an output movable sheave of the output clutch with replacement rollers having different masses and current ramps with replacement ramps having different slopes until the desired constant RPM output at the select RPM is achieved.
