Title: Self-braking device in rotator
Inventor: ASANO MASATOSHI
IPC: F16H37/02
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To save the energy by using a guide fixing disc as a guide wheel body. SOLUTION: A guide fixing disc 28 is fixed to a main spindle 22 adjacent to a rotating holding plate 23. Guide rollers 30... are rotatably screwed to screw holes 29... on the circumferential surface of the guide fixing disc 28. A load rope 32 turns about 360 deg., with one end thereof fastened to and held by a first holding shaft 25, around the guide fixing disc 28 through the load side thereof while it is successively pressed onto the guide roller group 30..., reaches the load side of the original position, and further reaches a second holding shaft 26, where the other end is fastened and held. When a load is added to a load small wheel 40, the load causes a tension in the load rope 32.  Since the second holding shaft 26 receives the load directional force by this tension, and the first holding shaft 25 travels in the opposite direction, the both mutually cannot move in any direction by mutual competition, and are laid in static state. Accordingly, since the load is self-braked by the load rope 32, the energy can be saved.

Abstract: PURPOSE:To detect the number of rotations of an engine at a high speed with good accuracy, by detecting the number of rotations of the engine by the detection during one combustion process while the rotational irregularity during one rotation is corrected. CONSTITUTION:By a detector 3 wherein detection parts 2 are formed and fixed to the outer peripheral surface of a circular rotary body 1 rotating along with the drive shaft of an engine at equal intervals in the circumferential direction in a number integer n-times the combustion number (m) of times of the engine during one rotation, the passing time interval Ti (i=1, 2, 3, 4...) of each detection part 2 is measured. This time interval Ti between teeth 2 after combustion is different from that between teeth 2 before combustion and wide and narrow intervals appear alternately. That is, the time interval is wide like T1, T3... before combustion is generated and narrow like T2, T4... after combustion. The number of rotations fi=60/mnTi(rpm) are calculated on the basis of these pulses by an operation apparatus. By this method, the average number of rotations are calculated according to formula and the number of rotations that is a correction of the irregularity of a rotational speed is obtained.
