The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Referring to figs. 1 through Fig. 5, the supporting tooling of power transmission shaft rotation of the present invention, is mainly comprised of main support seat, roller devices and drive unit three parts, below every part is elaborated:
Supporting base is comprised of the workbench 3 of base 1 and supporting rollern device.The longitudinal section of base 1 is " recessed " font.Workbench 3 is positioned on the upper surface of base.Base 1 is connected by a jack 4 with workbench 3, under the active force of jack 4, can make workbench 3 longitudinally moving up and down along base 1.The upper surface of described base 1 is provided with hole, the lower surface of workbench 3 be provided with a plurality of guide pillars 2, one end of each guide pillar 2 is fixedly connected with workbench 3, Kong Zhonghou and base formation that the other end of guide pillar is inserted on base 1 are slidably matched, the circumference wall of described guide pillar 2 is provided with keyway, the axially parallel of this keyway and guide pillar.The upper surface of described supporting base is provided with guide rail 5, and the section of this guide rail 5 is T-shaped.The two ends of guide rail 5 are fixedly connected with workbench 3 by screw, and the length direction interval along this guide rail on guide rail is furnished with several slots 5a.
The upper end of supporting base is relatively provided with a pair of roller devices, and each roller devices comprises roller mount 6, bolster 8 and roller 10, and bolster 8 is connected in roller mount 6, and roller 10 is connected on bolster 8.Described roller mount is provided with groove, and bolster 8 is arranged in groove and two end is fixed on the groove side wall of roller mount, is fixed with bearing 9 on bolster 8, and this bearing 9 is rolling bearing, roller 10 be enclosed within on bearing and with bearing 9 interference fit.Described roller 10 is the plastic roller of POM acetal resin material.Described roller mount 6 is slidably fitted on guide rail 5, the lower end and the guide rail 5 that are roller mount 6 are slidably matched, roller mount 6 translation on T shape guide rail has good linearity, described roller mount 6 is provided with a latch 7 being inserted in described slot, when large-scale, the heavy duty transmission axle of carrying, the horizontal shear force that latch 7 bears is quite large, so latch of the present invention 7 adopts high strength alloy steel to be made.The side wall surface of roller mount 6 is provided with chute 6a, and described latch 7 is slidably fitted in chute 6a.Latch 7 is provided with through hole, roller mount 6 is provided with the jack being positioned on described chute 6a diapire face, after the end of latch 7 is inserted in slot 6a, after passing the through hole on latch, a locking pin 7a is inserted in described jack, by locking pin, latch is locked in roller mount, to prevent that latch from privately sliding in chute.
Drive unit comprises bearing 11, reductor 13, and described bearing 11 is fixed on the side wall surface of supporting base, and reductor is fixed on bearing.
Use the present invention that large-scale power transmission shaft is assembled, cleaned, during the work such as check, adopt a pair of frock to match use, and power transmission shaft needs horizontal positioned.Before carrying power transmission shaft, first to measure the radius of bearing point place, power transmission shaft two ends shaft part, calculate both difference DELTA h; Then one end height is fixed, and the other end is used jack 4 that workbench 3 is promoted, and hoisting depth is Δ h; Finally power transmission shaft is lifted on the roller 10 of two frocks of pairing.If during work precision being had higher requirements in assembling, check etc., after the unloaded lifting of frock, power transmission shaft lifting put in place, power transmission shaft horizontal level still has error, can directly by the fine adjustment function of jack 4, finely tune until level.
As shown in Figure 4, when needs regulate width, first latch 7 is extracted out from the chute 6a of roller mount 6, pushing rolling wheels seat 6 moves, arrive behind precalculated position, latch 7 is inserted in the slot of roller mount 6, downwards until be inserted into the slot bottom of guide rail 5, thereby roller mount 6 and guide rail is fixed.The slot of roller mount 6 is identical with the slot shape of T shape guide rail 5, in roller mount 6, move to precalculated position, and suitably both slots are alignd in fine setting, then latch 7 is inserted in both slots, the six-freedom degree of roller mount 6 is completely restrained, has good supportive and stability.
As shown in Figure 5, when the power transmission shaft of the different diameters of axle of carrying carries out relevant work, frock need to be carried out the adjusting of width, and the size of width directly affects stability and the security of power transmission shaft rotation.Generally, when the axle center of the axle center of power transmission shaft 12 and roller 10 becomes equilateral triangle, two roller stress are comparatively even, stability and safe when power transmission shaft rotates.The diameter D1 of described POM acetal resin roller 10 of the present invention is 200mm, and the maximum dimension D 2 that this frock can be carried power transmission shaft is 1800mm.
As shown in Figure 6, assemble accordingly, clean, during the work such as check at the large-scale power transmission shaft 12 of carrying, frock of the present invention need to be matched use.First calculate the difference DELTA h of power transmission shaft two ends radius, the size of two roller mount widths is adjusted in the larger one end of diameter, and the frock of the other end promotes Δ h, and the size of adjustment width direction.Then power transmission shaft 12 is lifted into the work such as the enterprising luggage of frock is joined, cleaning, check.If still there is horizontal error, can directly by Manual hydraulic jack, carry out corresponding fine setting, until level.When manpower cannot be rotated power transmission shaft, can in the frock of any one end, coaxial reduction gear 13 be installed, connect shaft coupling power transmission shaft is rotated to work.And then complete the work such as assembling, check, cleaning.
The invention provides a kind of basic structure for large-scale power transmission shaft frock; method and the approach of this technical scheme of specific implementation are a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.In the present embodiment not clear and definite each part all available prior art realized.
