Description
The present invention relates to a kind of isolating ring and a kind of assembly method thereof that is used to separate with the guide roller bearing roller.
These known isolating rings have different model, and can be by metal, for example steel or bronze even made by plastic materials.The isolating ring that the present invention includes relates to a kind of two parts isolating rings of being made by plastic materials, and this isolating ring has one first annular ring spare and one second annular ring spare.The first annular ring spare has many spacers, and this spacer separates and axially protrude from the one side of annular ring spare along week with evenly distributing, and the second annular ring spare joins so that form the nested of this each roller with the free end of spacer.
In the bearing of this pattern, its outside rolling ring has relative raceway with inner rolling ring, many rollers in its isolating ring embed between raceway and with this raceway and contact, the longitudinal section profile that roller and raceway have, its radial buckling is greater than distance between outer raceway and the bearing axis, these can be by measuring perpendicular to raceway, thereby roller can move axially along raceway and can not be subjected to the obstruction of axial restraint in raceway, its objective is for the relativity shift of raceway and move axially, particularly for those undersized bearings, the hardness of isolating ring is enough to stand from the active force of skew roller just very important, when especially bearing is loaded on before its operating position.Yet the present invention is not limited to such bearing, but such isolating ring, it can be applicable to any in sealing is nested the roller bearing of guide roller.
The present invention is relevant with such roller separator, and here two parts wherein directly are connected with a kind of assembly apparatus as an assembling work step of bearing assembling.
Therefore roller is positioned to make the roller separate configuration between two bearing runners and by means of a kind of stretching, extension instrument, thereby the first annular ring spare of isolating ring is inserted into vertically, and separate the every pair of roller that adjoins with the spacer of a protrusion, the second annular ring spare joins with the free end of spacer, and this free end oppositely extends outside roller.
Another purpose of this isolating ring provides a kind of design of installing be convenient to as far as possible, and this reaches in the isolating ring that is limited.
Up to the present, the connection of two isolating ring parts is by riveted joint, bonding, welding or other similar Placement are implemented, or by designing connected surface portion thereby they being associated in together by interlock, the method for optimizing that connects is welding, because this danger that needs add ons and foreign substance pollution bearing inside is arranged unlike gluing unlike riveted joint.
Thereby, the purpose of this invention is to provide a kind of plastic barrier ring that axially has sufficient intensity at side direction or isolating ring so that bear the high pressure that may be subjected to, this realizes in the isolating ring that claim 1 limited subsequently.Another object of the present invention is the assembly method that this isolating ring is provided a kind of simplification, and this is limited by claims 5.
Thereby the present invention will be able to further elaboration by the described embodiment of qualification of accompanying drawing.

Fig. 6 shows half interconnective first and second parts according to Fig. 2 and Fig. 3 and isolating ring, and
Fig. 7,8 and 9 two parts that show the isolating ring that the present invention includes different linkage structure on cross section.
Fig. 1 shows half cross section of a bearing, this bearing comprises an inner ring 1 with outer raceway, outer ring 2 and many roller 3 with interior raceway, roller separates and guides between inner ring and outer ring and by isolating ring 4, the isolating ring of this pattern comprises two separated annular ring spares 5, with many spacers 6, spacer is linked together annular ring spare and together forms the nested of each roller 3.Described bearing is this pattern: wherein cylindrical rollers and raceway have cross section profile radius longitudinally basically, and these radius size are basic identical and in fact greater than the geometric radius of bearing.Race ring does not have the feature and the fact that flange or other prevention roller move, and bearing is born axially and radial load becomes possibility, thereby allows roller to move axially, and the roller of being loaded between the raceway produces eccentric mobile.In this bearing, exist might roller 3 end side to the danger of the ring spare 5 that presses isolating ring 4, especially when bearing runner 1,2 biasing and they rotate simultaneously, this is rare under common runnability, moved back and forth bearing in the past but be in the operation mounting point at it, this situation may often take place.
Bearing for this moderate size, application is by plastic materials, at least have great advantage by not having the isolating ring that very heavy characteristic material constitutes, but this also exists under the influence of lateral pressure, the plastic barrier ring has by crowded broken danger, the especially junction point between annular ring spare 5 and spacer 6.
Fig. 2 shows the radial cross section of first parts 7 of isolating ring according to the present invention.First parts 7 of isolating ring comprise an annular ring spare 8 with spacer 9 that many quilts evenly separate, and spacer and annular ring spare become one, and protrude from the plane of annular ring spare 8 vertically.The free end of each spacer 9 designs in a kind of optimized mode, and this point can better be found out in Fig. 4.Fig. 4 shows the zone that holds of Fig. 2 enlargedly, and these will be able to more detailed description in the connection there.
Fig. 3 shows the longitudinal section view of second parts 10 of isolating ring, second parts of isolating ring form the annular ring spare on a plane, its objective is and link to each other with the free end of the spacer 9 of first parts 7 and fixing, thereby the purpose of doing like this is to have many nested of rectangle that are essentially and can hold each roller 3 in order to form, and each rectangle is nested partly to be limited by two spacers that adjoin 9 and the annular ring spare that is attached thereto.The part of irising out of isolating ring second parts 10 among Fig. 3 is amplified in Fig. 5 and is illustrated, and these will be able to more detailed description there connecting.
Fig. 4 shows the part of irising out of Fig. 2 isolating ring first parts three-dimensionally, and shows the diagrammatic sketch of the preferred embodiment of isolating ring according to the present invention, as can be seen the part of annular ring spare 8 and protrude from the spacer 9 of annular ring spare.Spacer is tapered slightly and have one away from radially the part that diminishes.Each end face that connects spacer 9 is flat, but a groove 11 is arranged, and groove 11 has bottom 12, a plane and ramped side walls 13.Thereby the outer end of groove 11 is wideer than the bottom.
Fig. 5 shows the part of irising out of isolating ring second parts 10, and can find out that these isolating ring second parts comprise a bump 15 that is essentially the annular portion 14 on plane and has a flat side, bump 15 protrude vertically and its shape similar to the groove 11 of the first isolating ring parts 7 basically, similar to it, it also has inclined wall part 15a.
Fig. 6 shows isolating ring and has assembled shaping, isolating ring first parts 7 and second parts 10 enter with its bump 15 in the groove 11 of spacer 9 and interconnect, thus the plane annular part 14 of the second isolating ring parts 10 equally seal away from the annular ring spare 8 lateral margin lids of the first isolating ring parts 7 each nested 16.
The assembling of this isolating ring can help realizing with a kind of automatic bearing assembly machine that wherein interior rolling ring 1 and outer rolling ring 2 are positioned with its correlation, and roller 3 inserts between the raceways and separately puts so that they are in certain space.Therefore axially, isolating ring first parts insert between the rolling ring, and spacer 9 extends between every pair of roller that adjoins 3 simultaneously, thereby the free end of spacer 9 stretches out between roller 3.Therefore, isolating ring second parts 10 of formation lid enter groove 11 interior being positioned of spacer 9 by its bump 15, in this way, the bottom surface 12 of the outer surface of bump 15 and groove mutually combines and the free end plane of plane annular circle spare 14 and spacer mutually combines.
According to the present invention, the first and second isolating ring parts 7,10 preferably tightly are connected by ultrasonic welding each other by welding manner.Therefore the soldering tip (not shown) directly leans against on the junction plane between the spacer 9 and the second isolating ring parts 10, causes that by action of ultrasonic waves contact surface is melted together and connects.But also may be because of other welding method, here, the fusion effect also can reach and need not soldered splice and contact with direct physical between the face of mutually combining.These optional modes may be laser bonding or induction welding, after they all are used for the suitable surface treatment in joint.
Fig. 7 shows the configuration of fastening junction between spacer 9 and the lid shape second isolating ring parts 10 with diagram, also show simultaneously and have a little narrow crack 17 between solder bond face 18 and 19 (showing) with up-sizing, these solder bond places are positioned at separated horizontal plane, in that this side up, active force is expected to act on the isolating ring, for example on the axial direction of isolating ring.
Unexpectedly, it self has proved that above-mentioned welding joint position on Different Plane causes this welding joint and has bigger tension stress and flexural stress intensity with respect to the welding that identical even bigger face of weld are arranged, but this big face of weld only is positioned on the plane.
Fig. 8 and Fig. 9 show spacer 9a, the 9b and the second isolating ring parts 10a, 10b some the selectable design proposals between the fore side that are bonded with each other.
But so be designed to be inserted in the groove according to Fig. 8 embodiment's groove 11a and cover piece 10a with welding front cover part 10 interlocks, but welds joint 18a, 19a still is positioned on two different planes.
According to the embodiment of Fig. 9, spacer 9b has a semi-circular recesses and has similar shape with the bump of cover piece 10b.In this embodiment, might provide a continuous welds joint 18a at an easy rate, it directly is connected with welds joint 19b, even in this case, its weld strength is better than only being positioned at the welding joint intensity on a plane.
Compare with the common design that is contained in the free-ended annular isolation ring portion of other isolating ring parts spacer, the described cover piece 10 of design by this way, 10a, 10b has bigger advantage at fit on, here, the end of annular ring spare or spacer often has the finger piece of protrusion, these bumps will be included in the respective aperture of other element, simultaneously according to the present invention, the second lid shape isolating ring parts needn't accurately be located, its objective is and allow finger-like bump or like to find the accurate position relevant with respective aperture, but on assembly line, the second isolating ring parts be able to by one at random feeder be fed into its position.
The invention is not restricted to shown in the accompanying drawing and wherein connect described embodiment, but within the scope of the appended claims, revise with change also be possible.
