High-speed broad-width crawler belt conveyer
Technical field
The present invention relates to conveyer, particularly relate to a kind of high-speed broad-width crawler belt conveyer.
Background technology
Now in the industrial production, crawler belt conveyer plays important role always.Simple crawler belt conveyer adds crawler belt by two axles at two ends and forms.One of them axle general is imput shaft, and one is driven shaft, and imput shaft is connected with external motive device by drive disk assembly.Also having the imput shaft of some conveyers not need external motive device, such as electric roller, itself is exactly motor, and only needing is switched on power gets final product work.
Can produce vibration in crawler belt conveyer operation process, and often rotating speed is higher, transport tape breadth wider (axle is longer) vibration is more serious.Vibration can affect service life of a machine, and the serious machine that even can cause cannot work.Integrally, its vibration causes primarily of axle conveyer.There is absolute axisymmetric axle, during rotation, can not vibration be caused.If axle has the defect in certain bending or other processing, cause its overall barycenter or segmentation barycenter off-axis, during rotation, will vibration be brought.
Need wide cut, high-speed transfer machine in some application, improve breadth width and the speed of transmission of conveyer, first problems faced vibrates aggravation exactly! Reduce vibration most actv. means be improve the working accuracy of axle, make axle more close to rotational symmetry.This often makes tooling cost significantly improve.Some are used to the occasion of slender axles, even machine up is very superior, axle is meeting flexural deformation under the tension force effect of crawler belt, and the axoplasm heart can off-axis.
There is disclosed technology at present, the driven shaft of conveyer is made sectional type.This kind of axle has a fixing mandrel, and mandrel is installed multiple bearing, and in conveyer operational process, crawler belt band dynamic bearing rotates.Like this, during work, mandrel does not turn, and each section of bearing just mandrel overlapped turns, even if to occur to a certain degree bending for mandrel, also can not cause obvious vibration.This scheme effectively reduces the vibration that in conveyer working process, driven shaft causes, but the vibration problem that imput shaft causes cannot solve simply by this scheme.Relative to driven shaft, the vibration that imput shaft causes is often larger, and the difficulty reducing the vibration that imput shaft causes is also larger.
Summary of the invention
In order to the vibration caused when reducing conveyer running, improve the speed of transmission of crawler belt, the present invention proposes a kind of new solution.
Main technical schemes of the present invention is as follows:
A kind of high-speed broad-width crawler belt conveyer, as accompanying drawing 2, it comprises imput shaft 21, driven shaft 22, transmission crawler belt 23, support frame 24, intersegmental support 25 and other appurtenances.Its imput shaft 21, driven shaft 22 are all multiple stage.
As accompanying drawing 3, the present invention propose high-speed broad-width crawler belt conveyer, its imput shaft 21 is made up of a mandrel 213 and several sections of axle sleeves be arranged on mandrel, have in these axle sleeves powered-flight phase 211, driven section 212.Powered-flight phase 211 has the function of motor, and its rotor 2111 promotes crawler belt 23 and operates, and stator 2112 is fastened on mandrel; Driven section 212 functions without motor, are only plain shaft cover.As required, all sections of an imput shaft can be designed to powered-flight phase; Also can some powered-flight phase, driven section an of part, but have at least one section to be powered-flight phase.If all sections of its imput shaft are all powered-flight phases, the stator of powered-flight phase can be utilized to be spliced into mandrel, and not need an extra mandrel.
As required, can arrange intersegmental support 25 between the section of imput shaft and section, its quantity and installation form are determined as required.The situation of driven shaft roughly the same.
As required, each powered-flight phase of imput shaft can arrange speed feedback device, in order to control the rotating speed conformability of each powered-flight phase.
As accompanying drawing 4, the high-speed broad-width crawler belt conveyer that the present invention proposes, its driven shaft 22 is by a mandrel 223 and several sections of axle sleeve 222(be arranged on mandrel or bearing) form, these axle sleeves can independently rotate around mandrel.
The high-speed broad-width crawler belt conveyer that the present invention proposes, its transmission crawler belt connects imput shaft and driven shaft, and imput shaft drives crawler belt running, and then drives driven shaft running.Framework 24 plays a supportive role.
Compared with prior art, the advantage of described high-speed broad-width conveyer is: one, the master and slave moving axis of this conveyer is all multiple stage, and in its operation process, the mandrel of master and slave moving axis does not all rotate, just each axle sleeve rotates, because the length of each axle sleeve is much smaller than the length of mandrel, under identical radius of curvature, the distance of the barycenter off-axis of axle sleeve is less than the distance of mandrel barycenter off-axis, same cireular frequency, the vibration that the axle of this programme conveyer causes is little.Two, the length of axle, also namely the increase of conveyer fabric width can't sacrifice too many speed, is conducive to the conveyer manufacturing super large width.
