Title: speed controller
Inventor: IKEGAWA SHIORI
IPC: F16D59/00
Filed: 2020-10-02
Abstract: To provide a speed controller of which the variation range of a brake torque is wide.SOLUTION: A speed controller 2 comprises: a housing 4; a retainer 6 which is stored in the housing 4 freely movably in an axial direction; a spring member 8 which presses the retainer 6 to one side in the axial direction; a rotor 10 which is mounted in the housing 4 in a freely rotatable manner; and a weight 12 which is supported by the rotor 10 so as to be freely swung. An annular inclined plane 36 extending toward the outside in a radial direction while being inclined to one side in the axial direction is formed at an inner surface side edge of an end face wall 30 of the retainer 6. When the rotor 10 is rotated, the weight 12 is swung to the outside in the radial direction by a centrifugal force, the weight 12 and the annular inclined plane 36 are brought into contact, and a brake torque caused by a friction force between the weight 12 and the annular inclined plane 36 acts on the rotor 10. A moving amount of the retainer 6 to the other side in the axial direction increases in response to a rise of a rotation speed of the rotor 10 and a force of the spring member 8 pressing the retainer 6 to one side in the axial direction increases. Therefore, vertical drag in the annular inclined plane 36 increases and the brake torque increases.SELECTED DRAWING: Figure 1
