Detailed description of the invention
See figures.1.and.2, the interior cooling structure of conveying roller of the present utility model, comprises conveying roller body 1, power transmission shaft, bearing arrangement 2, also comprises the first support set 3, second support set 4 and water jacketing.Conveying roller body 1 is provided with axial through hole, first support set 3, second support set 4 is fixed on the internal face of the through hole of conveying roller body, first support set 3 and be interference fit between the second support set 4 and conveying roller body 1, weld again after interference fit, MT flaw detection is carried out before welding, postwelding carries out examination water test, guarantees sealing.After first support set 3 and the second support set 4 coordinate with conveying roller body 1, welded with conveying roller body 1 by the mode of spot welding.Described power transmission shaft is through after the first support set 3 and the second support set 4, the end winding support of power transmission shaft is on bearing arrangement 2, because the first support set 3 and the center of the second support set 4 and the inner surface of conveying roller body 1 have certain spacing, when power transmission shaft is supported on after on support set, also have certain spacing between the inner surface of power transmission shaft and conveying roller body 1, such spacing becomes the space that cooling water can be flowed wherein.Power transmission shaft is provided with axial water hole 5, described power transmission shaft is also provided with radial osculum 6, and this osculum 6 is interconnected with water hole 5.
Also comprise the 3rd support set 7 and the 4th support set 8,3rd support set 7 and the 4th support set 8 are between the first support set 3 and the second support set 4,3rd support set 7 and the 4th support set 8 equally also adopt interference fit with conveying roller body 1, and the 3rd support set 7 and the 4th support set 8 are provided with axial water-guiding hole 9.Power transmission shaft is made up of the first power transmission shaft 10 and second driving shaft 11, first power transmission shaft 10 is supported on the first support set 3 and the 3rd support set 7, second driving shaft 11 is supported on the second support set and the 4th support set 10, water hole 5 on first power transmission shaft 10 is blind hole, and the water hole 5 on second driving shaft 11 is through hole.Power transmission shaft is adopted two sections of power transmission shafts composition by the utility model, and two sections of power transmission shafts are separated by a segment distance in the axial direction, are conducive to reducing costs, and increase the inner space effectively holding cooling water of conveying roller body 1, make the better effects if of cooling.The axle body of the first power transmission shaft 10 and second driving shaft 11 is equipped with step, first power transmission shaft 10 is spacing between the first support set 3 and the axial end of the 3rd support set 4 by the step on its axle body, and second driving shaft 11 is spacing between the second support set 4 and the axial end of the 4th support set 8 by the step on its axle body.Two step end faces of the first power transmission shaft 10 weld respectively with between the first support set 3 and the axial end of the 3rd support set 7, welding after annealing, two step end faces of second driving shaft 11 weld respectively with between the second support set 4 and the axial end of the 4th support set 8, welding after annealing.
An end of power transmission shaft, from after described bearing arrangement passes, is connected with water jacketing.Water jacketing is provided with water inlet 12 and delivery port 13, and water inlet 12 is communicated with the water hole 5 of power transmission shaft with delivery port 13.Described water jacketing comprises mount pad 14 and water-supply-pipe 15, and water inlet 12 and delivery port 13 are arranged on mount pad 14, and water inlet 12 is arranged along the axis of mount pad, and delivery port 13 is arranged along the radial direction of mount pad, and the position of water inlet 12 is higher than delivery port 13.One end of water-supply-pipe 15 is connected with water inlet 12, the other end of water-supply-pipe 15 is inserted in the water hole 5 of power transmission shaft, and extend in the clearance space between the first power transmission shaft and second driving shaft, like this, the water exported from efferent duct first reaches the clearance space between the first power transmission shaft and second driving shaft, fill the air to surrounding from this clearance space again, thus fill the inner chamber of full whole conveying roller body 1.The external diameter of water-supply-pipe 15 is less than the aperture of the water hole 5 of power transmission shaft, makes to there is spacing between water-supply-pipe 15 and water-supply-pipe 5, is refluxed by this spacing to enable cooling water.
The utility model is not limited to above-mentioned embodiment, and such as, power transmission shaft of the present utility model can certainly adopt an overall major axis.For water jacketing, it can be only a mount pad 14, and without the need to water-supply-pipe, when it is on mount pad, water inlet 12 is arranged along the axis of mount pad, delivery port 13 is arranged along the radial direction of mount pad, but, the position of water inlet 12 is positioned at and lower than delivery port 13, like this, first will flow into water hole from the cooling water of water inlet input, after heat exchange, discharge from delivery port, although the water jacketing of this structure can play cooling effect, as above a kind of embodiment is not good for cooling effect again.
The course of work of the present utility model is (the current arrow as in Fig. 1 and this figure): be input to water pipe 15 by cooling water from water inlet 12, cooling water enters into the space at the interval between the first power transmission shaft 10 and second driving shaft 11 after water pipe 15 output, cooling water fills the air in this clearance space, cooling water enters into the space between the 3rd support set 7 and the first support set 3 respectively by water hole 5 and osculum, and enter into the space between the 4th support set 8 and the second support set 4 by water hole 5 and osculum 6, like this, the inner chamber of conveying roller body 1 fills up by cooling water, thus make the inner surface of conveying roller body 1 carry out heat exchange with cooling water all sidedly, the heat of inner surface is when reducing rapidly, its appearance table also promptly lowers heat through heat transfer, thus protect conveying roller body 1.Owing to inputting cooling water through water pipe 15 at the inner chamber constantly to conveying roller body 1, add upper roller body 1 inner chamber to have filled out and be filled with cooling water, the cooling water of new input defines squeezing action to original cooling water, force the gap of original cooling water between water pipe 15 and water hole 5 to flow in mount pad 14, drain from the delivery port 13 of mount pad 14.Like this, in the mode constantly circulated, make to be in all the time in the inner chamber of conveying roller body 1 to fill up cooling water, thus conveying roller body 1 is also in cooled state all the time.
