The specific embodiment
In the following description, identical part is endowed identical Reference numeral.Be noted that on the whole not in proportion drafting of accompanying drawing, and mainly only be used for illustrating embodiment of the present utility model.
Show in a simplified manner the structure according to the boots roller of the utility model the first embodiment among Fig. 1.The boots roller is loaded with for the treatment of fiber web, for example, is used for squeezing or smooth against second roller (that is, pair roller 108) at the nip that is formed between the roller.The belt sheath 101 of boots roller is comprised of band, has the boots 110 that form squeezing slit (Pressspalt) that is nip in the inside of this band.The press shoe 110 that is designated hereinafter simply as boots is loaded by the loading that can move from the below or support component 107, and described loading or support component 107 for example are the piston-cylinders-device of hydraulic action, and it is and is arranged on the supporting member with arranging.Should be pointed out that three such support components only exemplarily are shown in Fig. 1.The end 140 of supporting member 102 is by axle support member 104(bearing housing for example) be bearing on the roller external structure (for example framework of paper machine or floor 105).Preferably, it is non-rotatable that supporting member 102 is fixed in operating process, but the position of rotation of supporting member can be in the adjustment of axle support member place, with alignment roller.The two ends of belt sheath 101 are fixed on the end ring 130.Between end ring 130 and supporting member 102, end seal 103 is set, is used for being sealed in the lubricant space that roller inside forms.
For realizing the sliding-contact between belt sheath 101 and the boots 110, lubricant is transported to boots 110 via lubrication pressure pipeline 210.Lubrication pressure pipeline 210 is arranged on the inside of roller supporting member 102, and uses suitable deep hole drilling method (for example BTA method) to make.Lubrication pressure pipeline 210 on the whole length of supporting member 102 basically as the crow flies and be arranged essentially parallel to the Axis Extension of supporting member 102.In the inside of roller, many pipelines 260 that guide to boots 110 are connected to lubrication pressure pipeline 210.Lubricant is from the inboard of sheath 101, for example discharge from roller via passing away 109 from the oil groove 119 that is arranged in supporting member 102 belows, perhaps by be positioned at sheath inboard and be arranged on boots 110 " discharge side " lubricant strigil (saveall, save-all) and further discharge from roller via passing away.Passing away 109 in known manner with supporting member 102 combinations of roller, namely, be arranged between the top of I shape supporting member part and bottom part and adjoin in the recess of web of I shape supporting member, oil return can via with supply with identical face of carrier end, or carry out via the other end of supporting member 102.Fig. 1 also schematically shows the pipeline 230,240 that further is discussed below by way of example herein.
The flow cross section area of lubrication pressure pipeline 210 and supply pressure pipeline 220 can arrange as required, and the capacity of straight pipeline and the low pressure loss also are suitable for large output.Should be pointed out that to replace using described deep hole drilling method or additional method that the realization of lubrication pressure pipeline 210 and supply pressure pipeline 220 can be undertaken by any suitable method.
Fig. 2 shows according to the loading pipeline of the boots roller of the utility model the first embodiment and the structure of lubricated pipeline.For clarity sake, in Fig. 2, no matter be support component (loading piston) 107 or belt sheath 101 all is omitted.Inner by according to suitable deep hole drilling method (for example BTA method) boring at the web of the supporting member 102 of roller, form lubrication pressure pipeline 210 and supply pressure pipeline 220.Can see the opening that enters of pipeline in the end of supporting member.These two pipelines extend on the whole length of supporting member 102 basically as the crow flies, thereby are convenient to its cleaning and inspection, and have reduced the pressure oscillation in the pipeline.The support component 107 of boots 110 to be moved add motion pipeline (Plusbewegungs-Leitung) 240 and discharge support component 107 hydraulic pressure subtract motion pipeline (Minusbewegungs-Leitung) 230, be connected to supply pressure pipeline 220.Pipeline 230,240 is embedded in the supporting member 102 in known manner.
The rapid discharge line 250 of pressure is connected to pipeline 240, and is used for hydraulic oil is discharged into the recess of the web that adjoins the I shape supporting member.The lubricant supply of boots 110 is finished by the flexible pipe 260 that is connected to lubrication pressure pipeline 210, this flexible pipe is arranged on the supporting member 102 of roller, more particularly, this flexible pipe is arranged between the top part and bottom part that remains in the I shape supporting member, adjoins in the recess of web of I shape supporting member.Also can realize the 270a of lubricant supply department of the distolateral bearing of roller from lubrication pressure pipeline 210, thus, can partly reduce pressure line and pressure hose according to prior art.Alternately, the 270b of supply department that arranges in order to the distolateral bearing of lubricated roller from on-load pressure pipeline 220.
Fig. 3 shows the cross section according to the boots roller of the utility model the first embodiment, and wherein identical element is as shown in Figure 2.In the web of the I shape supporting member 102 of roller, by according to suitable deep hole drilling method (for example BTA method) boring, form lubrication pressure pipeline 210 and supply pressure pipeline 220.In order pipeline 210,220 to be placed in the web inside of supporting member 102, in the position that pipeline extends, the thickness of the web of I shape supporting member 102 has compared with prior art been strengthened, and so just obtains enough rigidity and the mechanical strength of supporting member 102.
Fig. 4 shows according to the loading pipeline of the boots roller of the utility model the second embodiment and the structure of lubricated pipeline.For clarity sake, in Fig. 4, no matter be support component (loading piston) 107 or belt sheath 101 all is omitted.In the web of the supporting member 102 of roller, by according to suitable deep hole drilling method (for example BTA method) boring, form the importing pipeline 420 of lubrication pressure pipeline 410 and supply pressure pipeline 430 and supply pressure pipeline.Supply pressure pipeline 430 now with the support component 107 of comparing closer to boots 110 described above, it is arranged in the top part of I shape supporting member, and is connected to the importing pipeline 420 of supply pressure pipeline by vertical drilled tunnel.
The cleaning of convenient supply pipeline and lubricated pipeline and inspection can be regarded as the technological merit of various embodiments of the present utility model, are applicable to possible application ﹠ design of the present utility model, and can do any restriction to protection domain.The simplification of the boots roll structure of realizing in addition, can be regarded as the technological merit of the various embodiments of the utility model.Reduce the technological merit that expensive assembly and operation also can be regarded as various embodiments of the present utility model, the improvement of the boots roller operating reliability that obtains is like this too as far as possible.What can be used as at last that the technological merit of various embodiments of the present utility model is mentioned is that the pressure loss that occurs in the junction has reduced, and obtains thus energy-conservation possibility.
Top description provides the limiting examples of embodiments more of the present utility model.It will be appreciated by those skilled in the art that the utility model is not limited to disclosed details, but also can realize in other equivalent mode.Some feature of embodiment set forth herein also can be used under the situation of further feature not having.
Above description only should be understood to this explanation as the utility model principle, and should not be understood to restriction of the present utility model.Therefore, protection domain of the present utility model is only limited by claim.
