It sets and is provided with balancing frame, certain distance is set between the balancing frame of two sides, center and circumferential position have been evenly arranged
Column slot, column slot internal vertical are equipped with card column, are mounted on balancing spring in the corresponding card column in two sides.
Working principle: input shaft and output shaft is arranged in power takeoff enclosure interior, carries out rotative power amplification transmitting, input shaft
Gear is installed with corresponding matching on output shaft to engage, when input shaft and output shaft rotation, gear engagement generates radial force,
Under cyclic load effect, two axis generating period phase reflexive deformations, the output adjustment disk at this moment installed on two axis, input are adjusted
It saves disk to start to work, in the rotation of two axis since two disk of effect of sliding bearing is fixed, and passes through buffering spiral shell when installation
Bar both ends mobile adjustable distance in thread groove, forces balancing spring to be in tensional state, i.e. generation pretension, when two
Axis generating period phase reflexive deformation, this pretension phase reflexive generating period back edge, force two axis deformation reduce or
Person returns normal, the curvature variation of two axis of guarantee, so that shaft member, bearing part the operation is stable, promote service life.
In order to more preferably guarantee the balance of two axis back edges, two sides buffer screw stem is provided in baffle-box inner end position
Balancing frame, is arranged certain distance between the balancing frame of two sides, and center and circumferential position have been evenly arranged column slot, in column slot
Portion is vertically installed with card column, and balancing spring is mounted in the corresponding card column in two sides, guarantees the drawing of uniform circular sexual balance distribution
Hui Li.
Technical solution usefulness provided by utility model device: it is directed to power takeoff input and output between centers periodicity work
Make bending deformation problem, designs a kind of adjustment disk device in two between centers, first pass through tune of the buffer screw stem in thread groove in advance
Section effect reaches normal condition, and certain pretension is arranged, and when power takeoff works, the opposite deformation of two axial periods is by periodicity
Opposing force balances, and guarantees the curvature variation of two axis, so that shaft member, bearing part the operation is stable, promote service life.
