Description
Technical Field
The invention relates to the field of industrial electromechanical application, in particular to a centrifugal force constant torque output device.
Background
Centrifugal force is a virtual force, which is an inertial force that moves a rotating object away from its center of rotation. In Newtonian mechanics, centrifugal force has been used to describe two different concepts, an inertial force, a balance of centripetal forces, observed under a non-inertial frame of reference. Under Lagrangian mechanics, centrifugal force is sometimes used to describe a generalized force at some generalized coordinate.
When the non-average disk rotates around the spindle, a set of centrifugal resultant forces is generated according to Newton's second law in a non-inertial system, wherein the magnitude of the resultant forces is equal to F=mv≡2/r (m-eccentric mass; v-eccentric mass circumferential speed; r-eccentric mass radius). The centrifugal force direction is away from the radial outer circle of the axle center and has potential energy flying out along the tangential direction, and in practical industrialized application and daily life, the following practical cases are common in which the centrifugal force can be effectively utilized for human service: many cases of the centrifugal separator, the centrifugal vibration exciter, the dewatering drum and the centrifugal speed regulating mechanism are direct utilization of centrifugal force, but industrialized practical cases of converting rotational torque output power by utilizing centrifugal force are unusual.
