The utility model designs according to the parallelogram of forces principle, cylindrical spring and symmetrical dished spring assembly are by the orbiting motion of roller on the roller relief printing plate, make spring and dish spring make a concerted effort remain constantly, the direction of power is always a straight line, does not have swing.Working principle is: the power that acts on the roller cam of spring is F1, the track of dished spring assembly by roller and flange acts on and is F2 making a concerted effort on the roller cam, moving up and down on stroke along with the roller cam, power F1 and power F2 are along with displacement also changes, but the F that makes a concerted effort of F1 and F2 is a constant value in whole behavior scope.When the roller flange moved from top to bottom, cylindrical spring power F1 was in continuous increase, direction upwards, dished spring assembly make a concerted effort by flange the track effect its reducing F2 gradually with withing joint efforts, direction makes progress.When the roller flange continues to move down, when roller reaches the hump of flange track (stroke 50%), making a concerted effort of disc spring force F2 is 0, and in this point, only spring is born load, and its bearing capacity equates with the F value.When flange continued to displacement, the elastic force F1 of main spring continued to increase, and direction makes progress, and the F2 that makes a concerted effort of dished spring assembly increases gradually, but direction is opposite with F1, is directed downwards.So in whole stroke range, its structure ouput force F is constant.
Advantage of the present utility model is:
A. suspension and support vertical displacement.Owing to adopted parallelogram principle, the entire mechanism symmetric arrangement makes and props up the complete vertical displacement of suspension centre, symmetry, no lateral force and moment.
B. frictional force is very little.Frictional force mainly is present between roller flange and the roller, and this force of rolling friction only needs to try every possible means on the machining accuracy of roller flange, just can solve.
C. easy for installation.Because the entire mechanism symmetric arrangement, novel constant-force spring hanger only need dispose a suspension point or directly be shelved on the steel fine strain of millet.
D. the load adjustment range is big, can reach 40-100%
E. compact structure.The thickness size aspect of entire mechanism. its size is littler.Device applicable to a lot of spaces anxiety.
The curve of this roller flange is finding the solution the differential equation in addition, in order to improve its solving precision, we have adopted the MATLAB program that it is found the solution, the quantity of putting on its curve of output can infinitely be increased, thereby guaranteed the precision of curve, made that the differential equation curve in digital control processing cam curve and the design fits like a glove.
