SPEED CONTROL APPARATUS

摘要

A control apparatus for synchronizing the speed of a rotating member with a variable speed input or for producing angular displacement of an output shaft in response to an input signal. The apparatus achieves correlation between the input and output by the use of a mechanical gear arrangement between the input and output shafts which arrangement produces angular displacement of a control member upon receipt of an input pulse or up variation of the speed of the input shaft from the output shaft. This displacement is then utilized to regulate an electrical speed control device, the flow to a hydraulic actuator, or a mechanical variable speed drive which adjusts the speed or displacement of the output shaft accordingly.
