Abstract
A method of making a rotationally symmetric body, particularly an annulus ( 1 ) for a planet gear carrier, said annulus comprising a tooth profile ( 2 ) and/or additional elements ( 3 ), and said method being a non-cutting shaping method comprising: working the tooth profile ( 2 ) and/or the additional elements ( 3 ) into a sheet metal strip ( 4 ), cutting the strip of sheet metal ( 4 ) into desired lengths before or after working in the tooth profile ( 2 ) and/or the additional elements ( 3 ), bending round the sheet metal strip ( 4 ) to form a rotationally symmetric body and fixing the ends of the strip of sheet metal strip( 4 ) to each other.
Description
Technical field
The present invention relates to a method, be used to make the internal gear of rotationally symmetric body, particularly planetary bearing block, it has profile of tooth and/or annex, wherein, adopts chipless to be shaped and makes.
Background technology
General known this rotationally symmetric body can be by rough forging spare through turning and milling manufacturing as internal gear.
But this rotationally symmetric body is owing to make complicated and very expensive.
Therefore EP-0 639 415 A2 disclose a kind of rotationally symmetric body, are obtained by the cold forming by means of prestretching or deep-draw and elongation and shear spinning by slab chipless ground.As particularly from accompanying drawing 1-11 seen, this manufacture method needs a large amount of manufacturing steps, same expense expenditure is too high.In addition, this manufacture method only is applicable to the sort of rotationally symmetric body, and it has the web district of at least one radial directed, by its cylindrical zone that can chipless is shaped.
Summary of the invention
Therefore purpose of the present invention is, a kind of method is provided, and is used to make the internal gear of rotationally symmetric body, particularly planetary bearing block, and it structurally is shaped according to the chipless of eliminating above-mentioned defective and can makes inexpensively.
Purpose of the present invention is achieved thus, promptly processes profile of tooth and/or annex at a band on the steel, should be with steel before processing or the back cutting to length of processing, this band steel is bent to rotationally symmetric body also will interfix with the end of steel.
In this manner, can make rotationally symmetric body, particularly annular solid by means of chipless is shaped inexpensively as the internal gear.
Of the present invention other constitute the theme of dependent claims 2-8.
In having the mode of advantage, the manufacturing chipless of profile of tooth and/or annex ground is by rolling, and punching press or distortion are carried out.Meanwhile, this also is the manufacture method with low cost that enough accuracy can be provided.
Fasten from this pass, rolling tool, stamping tool or warp tool design like this, make profile of tooth and/or annex have the position of desired castellated shape and/or annex after the bending of band steel.Be arranged on later on the inwall still on the outer wall according to profile of tooth, the flank of tooth must more or less tilt when making as straight band steel.
The end of band steel can interconnect by welding.
But also parts that can be shaped and to be fitted to each other on the end of band steel, wherein, these parts are during BENDING PROCESS and/or staggered afterwards hanging up.
In having the mode of advantage, these parts constitute as hook-type and/or the respective clearance on the T shape protuberance and the other end (stickfast joint) on band steel one end.No matter produce end thus and engage to each other, be on tangential or parallel with rotationally symmetric body, can both guarantee terminal good toward each other firm joint.According to the purposes of rotationally symmetric body, this stickfast engages enough.Can imagine that this joint is with low cost, because it can be by the punching press of band steel, distortion or cutting to length are made simultaneously.
According to the purposes of rotationally symmetric body and according to desired precision, under the situation that adopts stickfast to engage, the end of band steel also can add and be welded to each other, for example on the intermediate gaps of hook-type and/or T shape protuberance and respective clearance.
Two weld seams can certainly be set, and wherein, one is arranged in the intermediate gaps as described like that, and another is arranged on the end of hook-type and/or T shape protuberance and the bottom separately in gap.
Annex can be protuberance or the gap that is shaped at band steel upper side, its under the state that internal gear processes for example with the central axis parallel orientation.By these protuberances or gap, can be on miscellaneous part with this internal gear, on for example planetary bearing block, location or fixing.
Description of drawings
The invention will be further described now by simplification the accompanying drawing of the embodiment of the invention to be shown.Wherein:
Fig. 1 illustrates the perspective view by means of the planetary bearing block internal gear that processes of manufacture method manufacturing of the present invention;
Fig. 2 illustrates the side view of bigger band steel, has profile of tooth and the annex processed on the end face;
Fig. 3 illustrates the band steel on the corresponding perspective view with Fig. 2.
The specific embodiment
Specifically, adopt the internal gear on the planetary bearing block of 1 mark in Fig. 1-3, side has profile of tooth 2 within it.This profile of tooth constitutes as helical teeth.Have annex 3 on this external side of internal gear, they are made up of protuberance or gap.By means of these annexes, internal gear can be at the other machines parts, fixing or location on for example planetary bearing block and this base part.Can transmit revolving force arbitrarily thus.
Internal gear 1 according to Fig. 1 is made by band steel 4.Band steel 4 can be used as endless end material and exists, and the inside is by means of rolling, punching press and/or distortion and process profile of tooth 2 and annex 3.The Len req of band steel 4 can disconnect in view of the above.But also can be in advance the band steel of respective length be disconnected, and inside or top shaping profile of tooth and annex.
After the band steel with corresponding cutting to length bends to annular, end can be welded to each other, thereby form the firm internal gear of moulding.
