Description
Technical field
The utility model relates to a kind of roller kilns, and these roller kilns are used for drying or burn till various workpiece, and the utility model relates in particular to the roller kilns that on the rotating shaft of each roller, possess universal joint.
Background technology
Roller kilns are the stoves with following structure, that is, make roller in the inside of tunnel-shaped body of heater with a plurality of potteries of predetermined spacing configuration, and through rotating each roller at a predetermined velocity, when conveying is placed on the workpiece on the roller, it is heated.In general, each roller is driven by the drive unit of a side of the width that is located at body of heater, and the opposition side of each roller is supported by small-sized support rollers rotation freely.At this moment; The position at center of central shaft and the roller that supported by support rollers of driving shaft that it would be desirable drive unit is consistent; But in fact because the error of installment work or the distortion of roller self etc. can produce some off-centrings on length direction, above-below direction.Therefore, rotation that might roller can not successfully be carried out, and perhaps because the excessive bending load takes place on roller repeatedly, thereby makes roller self fatigue rupture.
For fear of this problem, of patent documentation 1 (TOHKEMY 2000-146449 communique), be that a universal joint is set between driving shaft and roller, if 1mm with interior off-centring, just can absorb in the past.But,, and also become the main cause that cost increases and the operating time increases if the permissible range that will make off-centring just needs installation accuracy less than 1mm.In addition, the above-mentioned unfavorable condition that causes because of precision is not up to standard also might take place.
The utility model content
The purpose of the utility model is to address the above problem; A kind of roller kilns are provided; These roller kilns can relax installation accuracy, cause obstacle also can not under the situation of 1mm the rotation of roller even if surpass in the permissible range of off-centring, and can prevent losing of roller.
The utility model of making in order to solve above-mentioned problem is a kind of roller kilns; Inside at body of heater disposes many rollers with preset space length; And the drive unit that utilizes the side be located at body of heater makes each roller rotation, it is characterized in that, between the driven shaft of the driving shaft of drive unit and roll side, the connecting axle that connects diaxon is set; And, link the other end of driven shaft and this connecting axle with second universal joint with an end of first universal joint binding driving shaft and this connecting axle.
And preferred first universal joint is made up of first sleeve and a plurality of connecting pin of heating resisting metal system, links driving shaft and connecting axle through first sleeve.
In addition, preferred second universal joint is made up of second sleeve and a plurality of connecting pin of heating resisting metal system, links connecting axle and driven shaft through second sleeve.
The utlity model has following beneficial effect.
Two places of the roller kilns of the utility model between the driven shaft of driving shaft and roll side are provided with universal joint.Thus; Can the permissible range of the off-centring of the center of driving shaft and roller and driven shaft be expanded to about 2mm; Thereby compare with such situation that place's universal joint is set in the past; Can relax installation accuracy, and then can alleviate excessive loads, can prevent losing of roller for the roller in the running.

The specific embodiment
Below expression the utility model preferred embodiment.
In Fig. 1, mark 1 is tunnel-shaped body of heater, and mark 2 is its sidewalls, and mark 3 is rollers of the sidewall configuration about perforation.
On the length direction of body of heater 1, dispose many rollers 3 with preset space length.Roller 3 is the ceramic preferably system rollers of hear resistance and elevated temperature strength, and preferably the pottery by SiC matter constitutes.Extend outside stove from the roller through hole 4 that is formed on the sidewall 2 at the two ends of roller 3, and the end of one of which side is supported by 5 rotations of small-sized support rollers freely, and the opposing party's end is driven by drive unit 6 and rotates.In this embodiment, seal box 11 is set, prevents that extraneous air from invading the inside of body of heater 1 in the two end portions of roller 3.Workpiece W is placed on the roller 3, follows the inside that is rotated in body of heater 1 of roller 3 to be transferred at a predetermined velocity, is heated by heaters such as omitting illustrated heater simultaneously.
Drive unit 6 can be and the chain drive-type that was in the past likewise driven many rollers 3 by chain; But adopt the gear drive formula of following structure in this embodiment; Promptly; In the end of each driving shaft 7 helical gear 8 is set, the driven wheel 10 that is driven by motor 9 is meshed with each helical gear 8, thereby make driving shaft 7 rotations.Driven wheel 10 is installed on the axle 12 of the length of the length direction extension of body of heater 1.
As shown in Figure 2, this driving shaft 7 links with the driven shaft that extends from roller 3 sides 13 in the inside of seal box 11.Moreover the driven shaft 13 of roller 3 sides is and was connected the axle on the hat part 14 of the end that keeps roller 3 with pin 15 in the past the samely.
As shown in Figure 3, between the driven shaft 13 of driving shaft 7 that extends from drive unit 6 and roller 3 sides, with the same direction of diaxon on be provided with the connecting axle 16 with the diaxon same diameter.One side's of driving shaft 7 and connecting axle 16 end links with first universal joint 17, and the opposing party's of driven shaft 13 and connecting axle 16 end links with second universal joint 18. Universal joint 17,18 is made up of 19,20 and two connecting pins 21,22,23,24 of sleeve of heating resisting metal systems such as stainless steel respectively, links driving shaft 7, connecting axle 16, driven shaft 13 successively through sleeve 19,20.
Particularly, near a side's of sleeve 19 end, squeeze into first connecting pin 21 with the mode that connects driving shaft 7 to diametric(al).In addition, near the opposing party's of sleeve 19 end, squeeze into second connecting pin 22 with the mode of a side's from connecting axle 16 to diametric(al) that connect end.Thereby these first connecting pins 21 and second connecting pin 22 are right angle orientation each other, constitute first universal joint 17.
Likewise, near a side's of sleeve 20 end, squeeze into the 3rd connecting pin 23 with the mode of the opposing party's from connecting axle 16 to diametric(al) that connect end.In addition, near the opposing party's of sleeve 20 end, squeeze into the 4th connecting pin 24 with the mode that connects driven shaft 13 to diametric(al).Thereby these the 3rd connecting pins 23 and the 4th connecting pin 24 are right angle orientation each other, constitute second universal joint 18.Moreover, in this embodiment, the 3rd connecting pin 23 is set as second connecting pin 22 with first universal joint 17 direction that meets at right angles.
In sum; Through between the driven shaft 13 of driving shaft 7 and roller 3 sides, universal joint 17,18 being set at two positions; Can the off-centring of the roller 3 of driving shaft 7 and support rollers 5 sides be absorbed about 2mm; Therefore with compared in the past, need be, and can relax installation accuracy cost labour aspect the center.Therefore in addition, the on-stream roller 3 that also can make successfully rotates, and has not can pair of rollers to apply the excessive bending load and can prevent various advantages such as losing of roller 3.
