Fig. 3: another sectional view of housing parts illustrated in figures 1 and 2.
Embodiment
Fig. 1 illustrate as unprocessed foundry goods according to the housing parts 10 that is used for retarder of the present utility model.Housing parts 10 has square matrix 13, and the cooling that is furnished with setting on matrix 13 refers to 14.Cooling refers to that 14 coolings that form rectangle refer to the zone.
Part cooling refers to that 14 are arranged on the base.This base forms the ridge of matrix.The width of base 15 refers to the width in zone corresponding to cooling.Base towards remaining cooling refer to the zone continuously transition be matrix 13.Another border of base 15 and cooling refer to that the zone terminates in formation one step on the matrix 13 together suddenly.
Cooling refers to that 14 have longitudinal layered time length along housing parts 10.Shown in Figure 3, be used to cool off the profile 18 that refers to 14 part areas and form bow-shaped sections, crooked plane or cylindrical section in other words, refer to the imaginary joint of 14 end 16 as cooling.The radius of bow-shaped section also can be crossed profile 18 and fluctuate.
In the state that assembles of housing parts 10, the approximate rotatable parts with retarder of profile 18 for example gear the surface or by rotating the corresponding match profiles that forms.Housing parts 10 seals the inner space of retarder in the mode that forms housing as cover piece.The rotatable parts of retarder are arranged in the inner space of retarder.Lubricant oil is filled the inner space of retarder at least in part.In the gear rotation process, refer to 14 spray lubrication oil in the gear floodlubrication oil and to the cooling of housing parts 10.Decide on rigging position, cooling refers to that 14 place lubricant oil or lubricating oil bath at least in part.
In another unshowned embodiment, replace cooling to refer to 14, on matrix, be furnished with radiating fin.Radiating fin or its end are designed to corresponding profile.
Aluminum alloy, especially EN AC-AlSi8Cu3 preferably are suitable as first material that is used for housing parts.This first material comprises aluminium at least or otherwise just comprises the composition that heat conduction is good.
Cooling medium pipeline 20 is cast in the matrix of housing parts 10.So housing parts 10 upwards surrounds cooling medium pipeline 20 fully in week.
Cooling medium pipeline 20 is made by second material.This second material is stainless steel/Corrosion Resisting Steel especially, for example X5CrNi18-10 or more senior.Second material has the fusing point higher than first material, and therefore in casting process, cooling medium pipeline 20 maintenance shapes and structure are constant.By using the corresponding second stable material, can also the housing parts 10 or first material not corroded or not have under the situation of the less capacity of heat transmission, transport corrosive cooling medium through cooling medium pipeline 20.
Additional advantage is, can utilize bigger pressure transportation cooling medium through cooling medium pipeline 20.Thus, cooling medium has higher flow velocity, has improved cooling effectiveness.In addition, this higher flow velocity has also caused housing parts 10 heat extraction more equably, because cooling medium is located in the end of cooling medium pipeline 20, that is to say before cooling medium flows out cooling medium pipeline 20, is not also heated especially doughtily.
Cooling medium pipeline 20 respectively has a connection piece 22 on its end.Link 22 is fixedlyed connected with cooling medium pipeline 20, for example welding.Link 22 has the outer radius bigger than cooling medium pipeline.Determine the size of the inside radius of link 22 like this, make link 22 can be pushed on the end that is set to cooling medium pipeline 20.By part bag casting link 22, additionally sealed the connection part between link 22 and the cooling medium pipeline 20.
The end regions of each link 22 all stretches out on a side 12 of housing parts 10.Preferably in columniform link, form internal thread.Thus, the pipeline that is used to import cooling medium easily spiral be connected cooling medium pipeline 20.For this purpose, especially on each link 22, respectively connect an intake line or a discharge conduit.By making link 22 protrude in housing parts 10, when spiral connected the cooling medium input device, the moment of reaction can directly act on the link 22.This has prevented the mechanical load of cooling medium pipeline 20 or 22 pairs of matrixes 13 of link
As can be seen from Figure 2, cooling medium pipeline 20 as pipe fitting chevron pattern/be arranged in the housing parts 10 in a plane with wriggling.Therefore, cooling medium pipeline 20 has straight length 26 and returns turnaround section 28.Straight length 26 is not parallel each other, because return turnaround section 28 crooked omiting above 180 °.In optional embodiment, time turnaround section also can have the bend angle less than 180 °.
Return turnaround section and preferably have bend angle between 179 ° to 182 °, especially be 180.56 °.When the radius of curvature of the permission that observe/has kept the cooling medium pipeline, can also utilize the volume of housing parts 10 better like this.Cooling effectiveness by all right adjustment housings parts 10 of different bend angle.
Heat mainly refers to that by cooling 14 import housing parts 10 into, and passes to the cooling medium that flows through cooling medium pipeline 20 by cooling medium pipeline 20 by this housing parts 10.Cooling liquid, especially water preferably are suitable as cooling medium.If can only obtain the chemical corrosivity cooling medium,, can correspondingly select second material, for example X6CrNiMoTi17-12-2 etc. so as seawater or brackish water.
The cooling of different length refers to that 14 absorb the number difference of heat.In order to derive these heats, in another unshowned embodiment, cooling medium pipeline 20 is arranged in the housing parts like this, makes exist density and the cooling of cooling medium pipeline 20 in housing parts 10 refer to that 14 property ground, length locality is relevant.This means, cooling is referred to 14 long situations, therefore cooling medium pipeline 20 occupies housing parts 10 big volumes also can derive more heat.
Therefore, the heat load of housing parts 10 is more even.This has prevented housing parts 10 distortion.Otherwise this distortion may cause blow-by.
The cooling medium pipeline preferably have 5mm between the 30mm, especially 10mm between the 20mm, the diameter of 15mm more preferably.Bending radius/the radius of curvature of returning turnaround section 28 15mm between the 35mm, preferred 20mm in the scope between the 25mm, especially be 22.5mm.In a further embodiment, bending radius can change in described embodiment's scope.
In the fringe region of square matrix, around ground, especially with the spacing of rule/equidistantly the be furnished with opening of perforation.By opening guide fixture in mounted state of these perforations, utilize this fixed block that housing parts 10 is fixed on the remainder of reducer shell.This is not shown in Fig. 1.
As the seal arrangement of housing parts, Locktite (happy safe) face seal is installed between the remainder of housing parts 10 and reducer shell with respect to the housing remainder.
In order to make described housing parts, at first cooling medium pipeline 20 is made pipe fitting, then under the situation of observing the radius of curvature that allows, cooling medium pipeline 20 is bent into desirable shape.Then on the cooling medium pipeline, install, especially weld the holder 30 that from Fig. 1 and Fig. 3, can see.Thus, in casting process subsequently, the cooling medium pipeline also keeps its crooked shape.
Before casting process, fixed connecting piece 22 on the end of cooling medium pipeline 20 also.
Cooling medium pipeline 20 and holder 30 are put into mold together.Holder 30 also is used at the fixing cooling medium pipeline 20 of mold.Then cast cooling medium pipeline 20 by the first material bag of housing parts 10.
Then, in link 22, process internal thread.In a kind of optional embodiment of this method, before casting, in link 22, form internal thread.
After cooling, housing parts 10 is post-treated as the foundry goods of finishing.The outstanding end regions of for example, isolating holder 30.Opening to edge beveling or polishing and formation perforation in matrix 13.
