Three Parallel Iterative HRC52 Hoist Brake Disc Spring

 The combined spring characteristic curve

(a) three parallel iterative method, schedule for 1 piece, stretch for 3 times.

(b) four pieces of series folding method, schedule for 4, stretch for 1 times.Low

(c) three parallel iterative method

, schedule for 3 pieces, elastic for 2 times.

Low for parallel iterative method decreasing curve and thickness of the disc spring of different parallel, series combination into a gradual curve, the weaker the spring must have overload protection design.

Note: when design

Low when the disc spring using a combination of series, must have a guide pin or coat ring, ring and guide pillar or coat must be heat treated to HRC52 degree after grinding and polishing.

Low installation of guide pillar and the tolerance clearance of shrapnel from the table below to find out when the coefficient of friction and avoid vibration

Low moment touch attack unceasingly, makes the life of the spring.Low when spring super load or sharp will stress relaxation creates an hysterical phenomenon and abrade the spring spring

.

Show the calculate of the elastic, schedule to 25 x12. 2 x0. 9 millimeter of reeds, for example, four slices of parallel folding four groups and 2 slices parallel folding four groups of comparison, can clearly see

Out of the friction force increases, the more parallel fold will produce greater friction.

Low compression of disc spring as possible within the range of 10% ~ 75%.
