Abstract
The invention discloses a method for machining a separated type outer ring of a small and medium-sized thin-wall crossed cylindrical roller turntable bearing. According to the method, the outer ring of the bearing is machined integrally and is lathed to form two half bodies; and the method comprises the following steps of: a, lathing, namely lathing the outer ring integrally, calculating the allowance of an end face and a roller path according to the size of the outer ring, connecting the two half outer rings partially, lathing the middles of the insides of the two half outer rings to form cutting grooves, and leaving cut-off guiding openings on outer diameters; b, drilling and performing heat treatment, namely drilling the outer ring integrally before performing the heat treatment, and performing the heat treatment integrally after drilling; c, grinding, namely in the processes of initial grinding, performing initial grinding on the outer ring integrally without cutting the outer ring off; before final grinding, performing hard lathing to cut the outer ring off along the cut-off guiding openings on the outer diameters, and marking assorted marks; and polishing a cut-off surface, and connecting the upper half outer ring and the lower half outer ring by using a connecting hole to form an integral outer ring, and performing final grinding. By the method, the problems of high deformation possibility during machining and difficulty in guaranteeing concentricity after assembly are solved.
Description
Technical field
The present invention relates to the technology of bearing, relate generally to a kind of middle-size and small-size thin-wall crossed cylindrical roller turntable bearing method for machining separated type outer ring.
Background technology
The middle-size and small-size thin-wall crossed cylindrical roller turntable bearing of outside dimension D≤500, design form is various, has a kind of robot bearing due to handling characteristics, wall thickness is thinner, is thought of as arming rolling element consent during design more, and outer ring is Split type structure, without clamping docking, integral quenching form.This structural advantages is: a, can select more cheap bearing steel; B, gain in strength; C, be easy to assembling.But also there is certain drawback: a in this kind of structure, due to axially thinner easy distortion after the split of outer ring, difficulty of processing is larger; B ,Yin outer ring is Split type structure, is not easy to keep with one heart after assembling.
For drawback a, produce that reason is mainly wall thickness and thickness is all thinner.This is due to product structure feature.
For drawback b, produce former therefore 1: connection holes exists gap; Former therefore 2: heat-treated deformation effect, because product design requires integral quenching, therefore all Drilling operations are joined and have been bored before must quenching, if split heat treatment, the connection holes of upper and lower two semi outer rings is out of shape easily inconsistent, causes hole dislocation etc.
Summary of the invention
This patent object is to provide a kind of middle-size and small-size thin-wall crossed cylindrical roller turntable bearing method for machining separated type outer ring, for solving the yielding and rear concentric problem of assurance that is difficult for of assembling of processing.
The present invention can adopt following technical scheme to realize: described bearing outer ring adopts first integral body to process car to break as the processing method of halved body again, and processing method process is as follows:
A: turning process: outer ring, with integral form Vehicle Processing, first calculates end face and raceway allowance according to the size of outer ring, two semi outer rings are only done part connection simultaneously, and bosom car goes out to cut off groove, and external diameter stays to cut off and draws mouth, so that hard car cuts off.
B: boring and Technology for Heating Processing: before the heat treatment of outer ring, integral body is holed, after boring, integral body is heat-treated.
C: grinding technique: preliminary grinding each operation Shi， outer ring wouldn't cut off, and integral body is carried out, is easy to the assurance of processing and precision like this; Before mill, along external diameter cut-out, draw a mouthful hard car and cut off and carry out supporting mark eventually; Section reconditioning; After the good section of reconditioning, along mark line, look for contraposition postpone, at locating hole, pack pin fluctuating plate centering into, and will connect up and down for after whole circle and carry out whole grinder order with connection holes, can guarantee preferably like this status requirement and every required precision of raceway.
That the present invention is mainly used in is processing thin-walled, arming rolling element consent, outer ring are Split type structure, without clamping docking, the middle-size and small-size crossed cylindrical roller turntable bearing of integral quenching form processing technology.The art of this patent adopts whole Vehicle Processing and the processing of part mill, both can make product strength strengthen, be beneficial to again the assurance of Vehicle Processing and mill machining accuracy, realize the uniformity of boring and the uniformity of heat treatment deformation simultaneously, accelerated product process, solved the yielding and outer ring of processing and be difficult for the problems such as concentric.

The specific embodiment
By reference to the accompanying drawings, specific embodiments of the invention are described.
Be a kind of middle-size and small-size thin-wall crossed cylindrical roller Tumbler disc bearing structure schematic diagram as shown in drawings, it comprises inner ring 1, upper semi outer rings 2, lower semi outer rings 3, cylindrical roller 4, upper and lower semi outer rings connects by connection holes 8 and joint bolt 5, on upper lower branch, there is locating hole 6, inside packs alignment pin 7 into, and object is to make lower branch location centering, installing hole 9 for being connected of miscellaneous part.
Above-mentioned bearing outer ring adopts first integral body to process car to break as the processing method of halved body again, and processing method process is as follows:
A: turning process: outer ring is with integral form Vehicle Processing.
Put 1: calculate end face and raceway allowance, and between mutual conversion relation;
Put 2: two semi outer rings and only do part connection, bosom car goes out to cut off groove, and external diameter stays to cut off and draws mouth, so that hard car cuts off.
B: boring and Technology for Heating Processing: integral body is holed before the heat treatment of outer ring, comprises installing hole, connection holes, locating hole etc., wherein locating hole can be made mal-distribution not affecting on serviceability basis, is easy to like this cut open rear upper and lower two parts and can misplace.After boring, integral body is heat-treated.Operation arranges to guarantee the uniformity of hole Working position like this, guarantees the uniformity of heat treatment deformation.
C: grinding technique:
