Planet differential mechanical work principle of the present invention is seen shown in Figure 6: motor reaches tie-rod H through the drive a that is fixed on the tie-rod H with power (rotating speed, torque), and makes it rotation; When two saw wheel equal diameters, the rotation linear speed of two saw wheels equates that also the rotating speed of centre wheel Ka, Kb is identical, and two planetary gear g do not rotate tie-rod H, and box of tricks does not play differential action, and this moment, centre wheel Ka, Kb, planetary gear g were as a whole as joining.When two saw wheel diameters variant or in the middle of a certain saw wheel when skidding is arranged; The rotation linear speed of two saw wheels is just unequal; The rotating speed of centre wheel Ka, Kb is also inequality; Between obvious two centre wheel Ka, the Kb relative motion has just been arranged, made planetary gear g rotate outer (revolution), rotated (rotation) around own axis on tie-rod H again with tie-rod H.
Because the number of teeth of the centre wheel Ka of planet differential mechanism, Kb equates; So its basic speed ratio=-1; Can get through calculate deriving: tie-rod H rotating speed at any time all be two centre wheel Ka, Kb rotating speed and 1/2, so planet differential mechanism can both distribute to a rational tachometer value reducing gear of two saw wheels by this rule under any operating mode.
Metal material sawing main motion of the present invention is through the two centre wheel planet differential gear negative sign mechanisms (hereinafter to be referred as 2K-H planet differential mechanism) of a cover 2K-H; Give the fixedly reducing gear of saw wheel, tensioning saw wheel with rotating speed, the torque distribution of power source output, make two saw wheels all carry out sawing work with the form of driving wheel.This structure type band sawing machine drives band saw machine with common single shaft and has compared following characteristics:
(1) under the situation of lathe general power constant (have at power more than needed); Automatically with rotating speed, torque distribution give the fixedly reducing gear of saw wheel, tensioning saw wheel with power source according to the sawing working condition through 2K-H planet differential mechanism; Effectively improve the power factor (PF) of motor, energy savings.
(2) do not have under the situation more than needed in the lathe general power, through rotating speed, the torque distribution of 2K-H planet differential mechanism, its lathe input power can increase about 1 times, the cutting multiplexing dynamic force.
(3) because fixedly saw wheel, tensioning saw wheel are driving wheel; So under, the isodiametric condition of two saw wheels identical at saw blade tension force; Its traction frictional force can double (not isometrical like two saw wheels, then need pass through Theoretical Calculation, just can draw the concrete numerical value of tractive force raising) in theory.
(4) because fixedly saw wheel, tensioning saw wheel are driving wheel; There is not the open circuit loss of drawing follower; Power attenuation can reduce about 4% in theory, energy savings (according to related data: the transmission efficiency of the 2K-H planetary differential negative sign mechanism that is increased can be disregarded).
(5) adding the critical condition in man-hour with single shaft driving band saw machine compares: its stock-removing efficiency can improve 1 times in theory.
(6) because 1 times of frictional force nominal increase is drawn in sawing, the saw wheel wear condition that drives band saw machine with single shaft is compared, and the saw wheel wear condition of the design's band saw machine can reduce by 1 times at least, and its saw wheel life-span is to be how much multiples to increase.
(7) because the increase of sawing traction frictional force, bands for band produces during sawing work skids, " vexed car " phenomenon greatly reduces, so produce the bands for band wearing and tearing of skidding, " vexed car " collapses the also greatly minimizing of probability of tooth.Add the critical condition in man-hour with single shaft driving band saw machine and compare, its saw blade is enhanced about more than once service life at least.
(8) can design, utilize the diameter difference of saw wheel, change the incision angle of bands for band.
(9) bands for band cutting linear speed can have level, stepless speed change mechanism or motor frequency conversion device to control adjustment through mechanical type.
Description through These characteristics can prove that the present invention is the band saw machine of a kind of rational in infrastructure, dependable performance, efficient energy-saving.
