Description
【０００１】[0001]
本考案は、転がり軸受とハウジング等に圧入時における樹脂切れを防ぐ膨張補 正軸受に関する。 The present invention relates to an expansion compensation bearing that prevents resin breakage during press fitting into a rolling bearing and a housing.
【０００２】[0002]
一般的に軸受は軸受鋼を用いて製作されているのに対し、一部内燃機関等のハ ウジング１にはアルミニウムの如き線膨張係数の比較的大きい軽合金が使用され ているため、使用条件によっては、該ハウジング１内に圧入される軸受外輪４の 外径との間に隙間ができ両者間にクリープが発生する。 Generally, bearings are made of bearing steel, but some housings such as internal combustion engines use light alloys with a relatively large linear expansion coefficient, such as aluminum. In some cases, a gap is formed between the outer diameter of the bearing outer ring 4 and the outer diameter of the bearing outer ring 4 which is press-fitted into the housing 1, and creep occurs between the two.
【０００３】 そこで、線膨張係数の比較的大きい樹脂材料をもって軸受外径にモールドする ことによりハウジング１が膨張した場合でも、該ハウジング１の内径と軸受外径 との間が隙間が形成されることなく、前記ハウジング１に軸受が固定されること により、両者間のクリープが防止される。Therefore, even when the housing 1 expands by molding a resin material having a relatively large linear expansion coefficient to the bearing outer diameter, a gap is formed between the housing 1 inner diameter and the bearing outer diameter. Instead, the bearing is fixed to the housing 1 to prevent creep between the two.
【０００４】 樹脂材料がモールドされる周溝３の形状は外輪４の割れ防止のためにｒ≦Ｒに 形成され、さらにモールドされた樹脂外径寸法が外輪外径寸法よりも大きく形成 されているのが通例である。（図６〜図８参照）The shape of the circumferential groove 3 in which the resin material is molded is formed to r ≦ R in order to prevent cracking of the outer ring 4, and the outer diameter dimension of the molded resin is formed larger than the outer ring outer dimension dimension. Is customary. (See FIGS. 6 to 8)
【０００５】[0005]
要するに、周溝３の形状ｒ≦Ｒであり、かつハウジング内径が軸受外径よりも 小さいため圧入時の樹脂５が図９〜図１１に示す如く前記周溝３より押し出され ると共に切断されるという欠陥が生じた。 In short, since the shape of the peripheral groove 3 is r ≦ R and the inner diameter of the housing is smaller than the outer diameter of the bearing, the resin 5 at the time of press fitting is pushed out from the peripheral groove 3 and cut as shown in FIGS. 9 to 11. There was a defect.
【０００６】 そこで、この圧入時の樹脂切れを防ぐには如何なる手段を講じればよいかとい う事が本考案の技術的課題である。Therefore, it is a technical subject of the present invention what kind of means should be taken to prevent the resin breakage at the time of press-fitting.
【０００７】[0007]
上記技術的課題を解決するための手段は次の通りである。 すなわち、膨張補正軸受は転がり軸受の外輪に周溝を形成し、該周溝に樹脂材 料を装着せしめてなる転がり軸受において、該外輪の周溝に形成された樹脂部外 径の外輪端面側が傾斜角を設けてなることにある。 Means for solving the above technical problems are as follows. That is, in the expansion-correcting bearing, in a rolling bearing in which a peripheral groove is formed in the outer ring of the rolling bearing and a resin material is mounted in the peripheral groove, the outer ring end surface side of the outer diameter of the resin portion formed in the peripheral groove of the outer ring is There is an inclination angle.
【０００８】[0008]
樹脂部外径の外輪端面側に１０゜〜４５゜の傾斜角度を設けることにより、圧 入時の樹脂は軸受中心方向に押さえつけられ、周溝から押し出されることがない から、該樹脂の切断が防止される。 By providing an inclination angle of 10 ° to 45 ° on the outer ring end face side of the outer diameter of the resin part, the resin is pressed toward the center of the bearing during press fitting and is not pushed out from the circumferential groove. To be prevented.
【０００９】 又、この時ハウジングの内径には１０゜〜３０゜の面取りがあることにより、 樹脂の押し出しがより少なくなる。Further, at this time, since the inner diameter of the housing has a chamfer of 10 ° to 30 °, the resin is less extruded.
【００１０】[0010]
以下図に基づいて本考案の一実施例を説明する。 図１は本考案膨張補正軸受の縦断正面図である。 軌道１１，２１が形成された内・外輪２０，１０間に保持器４０を介して複数 の転動体３０が挿入されてなる転がり軸受が形成されている。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a vertical sectional front view of an expansion compensation bearing according to the present invention. A rolling bearing is formed by inserting a plurality of rolling elements 30 via a cage 40 between the inner and outer rings 20, 10 in which the raceways 11, 21 are formed.
【００１１】 該外輪１０の外径１２上に複数の周溝１３，１３が形成されている。 ５０は樹脂材で主としてナイロン６６，ナイロン１１、Ｐ．Ｂ．Ｔ等の材料が 使用される。 前記周溝１３はｒ≦Ｒなる円弧１３１，１３２をもって形成されている。A plurality of circumferential grooves 13, 13 are formed on the outer diameter 12 of the outer ring 10. 50 is a resin material, mainly nylon 66, nylon 11, P.I. B. Materials such as T are used. The circumferential groove 13 is formed with arcs 131 and 132 where r ≦ R.
【００１２】 又前記樹脂材５０の外径は外輪１０の外径１２より約１０〜９０ミクロン程度 大きく形成されている。 そして、該樹脂材５０の軸受端面側５０１には１０゜〜４５゜の傾斜角θが設 けられている。 この傾斜角θにより、外輪１０をハウジング６０に圧入するさいに樹脂を軸受 中心方向に押し付ける機能を有する。The outer diameter of the resin material 50 is larger than the outer diameter 12 of the outer ring 10 by about 10 to 90 μm. The bearing end face side 501 of the resin material 50 is provided with an inclination angle θ of 10 ° to 45 °. This inclination angle θ has a function of pressing the resin toward the bearing center when the outer ring 10 is press-fitted into the housing 60.
【００１３】 図３は本考案の他の実施例を示す要部拡大断面図で、前記第１実施例と異なる ところは、傾斜角θが周溝１３外輪外径１２の交点１３３より始まっている点に ある。 その他は前記第１実施例と同一につき、かつ作用効果に差がないから同一個所 には同符号を付し、その説明を省略する。FIG. 3 is an enlarged cross-sectional view of an essential part showing another embodiment of the present invention. The difference from the first embodiment is that the inclination angle θ starts from the intersection 133 of the outer circumference 12 of the circumferential groove 13. There is a point. Others are the same as those in the first embodiment, and since there is no difference in operation and effect, the same parts are designated by the same reference numerals and the description thereof is omitted.
【００１４】 図４は本考案の他の実施例を示す要部拡大断面図で、前記第１実施例と異なる ところは、傾斜角θが周溝１３の壁面１３４から始まって、反対側壁面１３５に 終わっている点にある。 その他は前記第１実施例と同一につき、かつ作用効果に差がないから同一個所 には同符号を付し、その説明を省略する。FIG. 4 is an enlarged cross-sectional view of an essential part of another embodiment of the present invention. Unlike the first embodiment, the inclination angle θ starts from the wall surface 134 of the circumferential groove 13 and the opposite side wall surface 135. The point is that it has ended. Others are the same as those in the first embodiment, and since there is no difference in operation and effect, the same parts are designated by the same reference numerals and the description thereof is omitted.
【００１５】 図５は本考案の他の実施例を示す要部拡大断面図で、前記第１実施例と異なる ところは、樹脂５０の傾斜角θが反軸受端面側５０２にも形成されている。 その他は前記第１実施例と同一につき、かつ作用効果に差がないから同一個所 には同符号を付し、その説明を省略する。FIG. 5 is an enlarged sectional view of an essential part showing another embodiment of the present invention. Unlike the first embodiment, the inclination angle θ of the resin 50 is also formed on the opposite bearing end face side 502. . Others are the same as those in the first embodiment, and since there is no difference in operation and effect, the same parts are designated by the same reference numerals and the description thereof is omitted.
【００１６】 次に、従来品と本考案を同一押圧力をもって圧入した場合の実験データを表１ にして示す。Next, Table 1 shows experimental data when the conventional product and the present invention are press-fitted with the same pressing force.

【００１７】[0017]
樹脂部外径の外輪端面側に傾斜角を設けることによって、膨張補正軸受をハウ ジングに圧入するさい、樹脂は軸受中心方向に押し付けられる結果、前記ハウジ ングによって押し出されることがなくなり、樹脂切れを防止することができる等 本考案特有の機能を有する。 By providing an inclination angle on the outer ring end surface side of the resin part outer diameter, when the expansion compensation bearing is pressed into the housing, the resin is pressed toward the bearing center, and as a result, it is not pushed out by the housing and the resin breaks. It has a unique function of the present invention such as prevention.
【００１８】 従って、ハウジングの膨張に追従して樹脂部が膨張するため、両者間の隙間が 生じない、それゆえ両者間のクリープの発生を防ぐことができる等格別の効果を 奏する。Therefore, since the resin portion expands in accordance with the expansion of the housing, a gap between the two does not occur, and therefore, it is possible to prevent the occurrence of creep between the two, which is particularly advantageous.
