99114121.0 number application for a patent for invention discloses the obvious difference of a kind of interactive constant force dish spring support hanger frame (publication number CN1268641A) this suspension and support and No. 91106977.1 patent applications and has been: solved the offset problem at the pull bar vertical center line, movable front pressuring plate is provided with circular-arc groove, be provided with ball in the groove, frictional force when reducing shell and making arcuate movement, this has certain good effect really to the problem that solves No. 91106977.1 patent existence, but, when pull bar drives when the belleville spring assembly housing being housed making arcuate movement, need still that pull bar is double to play the guiding role.And above-mentioned patent application does not all have load continuous stepless controlling device.
Summary of the invention:
The objective of the invention is to: the problem to No. 91106977.1, No. 99114121.0 patent application implementation process existence provides a kind of new interactive connecting plate constant force disk spring supporting hanger.
The object of the present invention is achieved like this: a kind of interactive connecting plate constant force disk spring supporting hanger, comprise housing, the belleville spring group, pull bar, pressing plate, fixed frame, slewing frame and connecting plate, slewing frame is movably connected on the fixed frame through main shaft, slewing frame is provided with pull rod shaft and load axle, the pull bar that is provided with on the pull rod shaft runs through the belleville spring group and is connected on the pressing plate, it is characterized in that: the paired closed assembly of belleville spring is in shell, the housing front end is provided with the revolution top board, the revolution top board is movably connected on the fixed frame by fulcrum, be equipped with coupling bar on revolution top board and the slewing frame, flexibly connect by link between two coupling bars.
The invention has the advantages that: during work, when the load axle drives slewing frame when main shaft rotates, connecting plate between slewing frame and the revolution top board drives the revolution top board simultaneously and rotates along fulcrum, because revolution top board and housing are whole admittedly, under the drive of connecting plate, revolution top board and housing will be made circular movement along fulcrum, pull bar is only born the elastic force of belleville spring, simultaneously after the deadweight of belleville spring group under the drive of connecting plate is supported by the fulcrum fulcrum, be reacted on the slewing frame, it is big to become initial force, (deadweight of the vertical line size of coupling bar and belleville spring group is initial to stopping changing not quite on the revolution top board for the stealthy counterweight that termination power is little, but the vertical line size of coupling bar is initial to stop being two times of relations on the slewing frame) just in time remedy the characteristic curve of belleville spring power, this shows, it is direct drive by connecting plate, solved present disc spring bearing hanger middle shell when fan shape moving, pull bar is because of the double frictional force that play the guiding role and produce, product invariance degree performance is improved, mix the controlling mechanism that is applicable to heavy load again, therefore the interactive connecting plate constant force disk spring supporting hanger that the present invention relates to is compact structure not only, functional, Perfect in shape and function, and the load regulation range is big.
