Description
【０００１】[0001]
本考案は、各種自動販売機、金融機器、発券機の紙幣（カード）識別、搬送機 構などにおいて使用されるラバーモールド軸受に関する。 The present invention relates to a rubber mold bearing used in various vending machines, financial instruments, banknote (card) identification of ticket issuing machines, transport mechanisms, and the like.
【０００２】[0002]
ラバーモールド軸受は、軸受鋼あるいはステンレス鋼からなる軸受の外輪の外 径面にゴムを焼付け接着したものであるが、ゴムは、ゴム自身の焼付け成形によ る付着力と外輪の外径面に予め薄く塗布された接着剤の接着力によって外輪に強 固に保持されている。従来、このようなラバーモールド軸受の外輪は、旋削→ 熱処理→外径面研削→転走面研削→外径面ショットブラスト→外径面 接着剤塗布→ゴム焼付け成形→ゴム外径研削といった工程を経て製造されて いた。転走面研削までは標準軸受の外輪（以下、標準軸受外輪という。）と全 く同一の工程であり、外径面ショットブラスト以降がラバーモールド軸受特有 の工程である。すなわち、従来は、標準軸受外輪をそのまま使用して（他の軸受 部品も標準軸受部品をそのまま使用している）、これに、別途、ゴム成形加工を 施すことによってラバーモールド軸受とするのが通例であった。接着剤の塗布前 、外輪の外径面にショットブラスト加工を施すのは、外径面研削を経て表面粗 さＲｍａｘ＝２ｓ程度に仕上げられた標準軸受外輪の外径面を適度に粗くするこ とによって、ゴムの焼付け成形による付着力および接着剤の接着力を高め、以て 、ゴムの保持力を確保するためである。 Rubber-molded bearings are made by baking and adhering rubber to the outer surface of the outer ring of bearings made of bearing steel or stainless steel.The rubber is attached to the outer surface of the outer ring by the adhesive force of the rubber itself by baking. It is firmly held on the outer ring by the adhesive force of the thinly applied adhesive. Conventionally, the outer ring of such a rubber mold bearing has the following processes: turning → heat treatment → outer surface grinding → rolling surface grinding → outer surface shot blasting → outer surface adhesive application → rubber baking molding → rubber outer diameter grinding. It was manufactured after that. Up to the rolling surface grinding, the process is the same as that of the outer ring of the standard bearing (hereinafter referred to as the standard bearing outer ring). That is, conventionally, it is customary to use the standard bearing outer ring as it is (the other bearing parts also use the standard bearing part as it is), and separately form rubber molding into a rubber molded bearing. Met. Before applying the adhesive, the outer surface of the outer ring is subjected to shot blasting so that the outer surface of the standard bearing outer ring, which has been finished to a surface roughness Rmax = 2 s after grinding the outer surface, is appropriately roughened. This is to increase the adhesive force of the rubber by bake molding and the adhesive force of the adhesive, thereby ensuring the rubber holding force.
【０００３】[0003]
ショットブラスト加工は、鋼球粒子などのショットを被加工材表面に高速で吹 き付ける加工法であるが、一般に、被加工材よりも硬度の高い粒子をショットと して用いる。ところが、上記製造工程において、軸受外輪の硬度は熱処理によ ってＨＲＣ６０程度と非常に高くなっており、それよりも硬度の高い高硬度のシ ョットを用いる外径面ショットブラストは加工コストが高く、ゴム成形のため の総コストに占めるコスト割合が高くなる傾向にある。 Shot blasting is a processing method in which shots such as steel ball particles are sprayed onto the surface of a work material at high speed, but generally particles with a higher hardness than the work material are used as shots. However, in the above manufacturing process, the hardness of the bearing outer ring is extremely high at about HRC60 due to the heat treatment, and the outer surface shot blast using a high hardness shot with higher hardness is higher in processing cost. However, the cost ratio to the total cost for rubber molding tends to increase.
【０００４】 また、外径面ショットブラストは、通常、軸受組み立て後に行なわれており 、ショットが軸受内に侵入する懸念もある。Further, the outer diameter surface shot blasting is usually performed after the bearing is assembled, and there is a concern that the shot may enter the bearing.
【０００５】 本考案の目的は、ラバーモールド軸受におけるゴム保持力の維持向上を図ると 共に、製造工程の簡略化、コスト低減を図ることにある。An object of the present invention is to maintain and improve the rubber holding force in a rubber mold bearing, and to simplify the manufacturing process and reduce the cost.

本考案のラバーモールド軸受は、軸受外輪の外径面にゴムを焼付け接着したも のにおいて、軸受外輪の外径面が標準軸受外輪の外径面よりも粗い研削目を有す ることを特徴とするものである。 The rubber-molded bearing of the present invention is characterized in that the outer diameter surface of the bearing outer ring has a rougher grind than the outer diameter surface of the standard bearing outer ring when the outer diameter surface of the bearing outer ring is baked and adhered. It is what
【０００７】 また、上記構成において、外径面が表面粗さＲｍａｘ＝４ｓ〜１０ｓの研削目 を有するものである。Further, in the above-mentioned configuration, the outer diameter surface has a ground surface having a surface roughness Rmax of 4s to 10s.
【０００８】[0008]
軸受外輪の外径面を、標準軸受外輪の外径面よりも粗い研削目を有する表面性 状とすることにより、ショットブラストを施さなくても、ゴムの保持力を確保す るのに適した表面粗さを得ることができる。また、ショットブラストによる外径 面がディンプル状の方向性をもたない粗さ面であるのに対し、研削目を有する外 径面は筋目状の方向性をもった粗さ面である。そのため、ゴムの焼付け成形によ る付着力および接着剤の接着力が高く、ゴムの外径面への保持力が従来に比べ向 上する。 By making the outer diameter surface of the bearing outer ring to have a surface with coarser grinds than the outer diameter surface of the standard bearing outer ring, it is suitable for securing the holding force of rubber without shot blasting. The surface roughness can be obtained. Further, the outer diameter surface formed by shot blasting is a rough surface having no dimple-like directionality, whereas the outer diameter surface having a grind is a rough surface having a streak-like directionality. Therefore, the adhesive force of the rubber by baking and the adhesive force of the adhesive are high, and the holding force of the rubber on the outer diameter surface is improved as compared with the conventional one.
【０００９】[0009]
以下、本考案の実施例について説明する。 Embodiments of the present invention will be described below.
【００１０】 図１に示すラバーモールド軸受は、小径玉軸受１０の外輪１２の外径面１２ａ にエーテル系又はエステル系のポリウレタンゴム１７を焼付け接着したものであ る。外径面１２ａとゴム１７との間には、接着剤１８が介在している。内輪１３ 、ボール１４、保持器１５、シール１６はすべて標準軸受部品をそのまま使用し ている。The rubber molded bearing shown in FIG. 1 is formed by baking and adhering an ether type or ester type polyurethane rubber 17 to the outer diameter surface 12 a of the outer ring 12 of the small diameter ball bearing 10. An adhesive 18 is interposed between the outer diameter surface 12a and the rubber 17. The inner ring 13, the ball 14, the cage 15, and the seal 16 are all standard bearing parts.
【００１１】 外輪１２は、旋削→熱処理→外径面粗研削→転走面研削→外径面接 着剤塗布→ゴム焼付け成形→ゴム外径研削といった工程を経て製造される。 従来工程におけるショットブラストはなされていない。熱処理を終えた外輪素 材の外径面は、外径面粗研削によって表面粗さＲｍａｘ＝４ｓ〜１０ｓ程度に 仕上げられる。あるいは、標準軸受外輪の外径面（一般に、外径面研削を経て表 面粗さＲｍａｘ＝２ｓ程度に仕上げられている）に再度粗研削を施して上記粗さ 程度に仕上げても良い。The outer ring 12 is manufactured through the steps of turning, heat treatment, outer surface rough grinding, rolling surface grinding, outer surface adhesive application, rubber baking, and rubber outer diameter grinding. Shot blasting in the conventional process is not performed. The outer diameter surface of the outer ring material after the heat treatment is finished to have a surface roughness Rmax of about 4s to 10s by rough grinding of the outer diameter surface. Alternatively, the outer diameter surface of the standard bearing outer ring (generally, after the outer diameter surface grinding, the surface roughness is finished to about Rmax = 2 s) may be subjected to rough grinding again to finish to the above roughness.
【００１２】 図２に拡大して示すように、外輪１２の外径面１２ａには比較的粗い研削目１ ２ａ１があり、ゴム１７が接着剤１８の薄い層を介して外径面１２ａに密着して いる。尚、同図では、研削目１２ａ１の大きさ、接着剤１８の厚さがかなり誇張 されている。研削目１２ａ１は外径面粗研削（あるいは、標準軸受外輪の再研 削）によって形成されたもので、研削砥石（図示省略）の摺動に対応して、外径 面１２ａを円周方向あるいは交差方向に筋目状に走っている。従来のショットブ ラストによる外径面がディンプル状の方向性をもたない粗さ面であるのに対し、 外径面１２ａは筋目状の方向性をもった粗さ面である。As shown in an enlarged manner in FIG. 2, the outer diameter surface 12 a of the outer ring 12 has relatively coarse grinding lines 12 a 1, and the rubber 17 adheres to the outer diameter surface 12 a via a thin layer of the adhesive 18. is doing. In the figure, the size of the grind 12a1 and the thickness of the adhesive 18 are greatly exaggerated. The grinds 12a1 are formed by rough grinding of the outer diameter surface (or re-grinding of the standard bearing outer ring), and the outer diameter surface 12a is circumferentially or in correspondence with sliding of a grinding wheel (not shown). It runs in a crosswise direction. Whereas the outer diameter surface formed by the conventional shot blast is a rough surface having no dimple-like directionality, the outer diameter surface 12a is a rough surface having a linear shape.
【００１３】 外径面１２ａがこのような表面性状を有するため、ゴム１７の焼付け成形によ る付着力および接着剤１８の接着力が高く、ゴム１７の外径面１２ａへの保持力 が従来に比べ向上するばかりでなく、ショットブラスト加工が不要になるため、 製造工程の簡略化、コスト低減を図ることができる。Since the outer diameter surface 12a has such a surface texture, the adhesive force of the baking molding of the rubber 17 and the adhesive force of the adhesive 18 are high, and the holding force of the rubber 17 on the outer diameter surface 12a is conventionally. Not only is it improved, but shot blasting is not required, so the manufacturing process can be simplified and costs can be reduced.
【００１４】[0014]
以上説明したように、本考案によれば、軸受外輪の外径面が標準軸受外輪の外 径面よりも粗い研削目を有するので、外径面に焼付け接着したゴムの保持力が従 来に比べ向上するばかりでなく、ショットブラスト加工が不要になるので、製造 工程の簡略化、コスト低減を図ることができる。このような効果は、外径面が表 面粗さＲｍａｘ＝４ｓ〜１０ｓの研削目を有する時、より一層顕著に発揮される 。 As described above, according to the present invention, since the outer diameter surface of the bearing outer ring has a coarser grind than the outer diameter surface of the standard bearing outer ring, the holding force of the rubber which is baked and adhered to the outer diameter surface is conventionally. Not only is it improved, but shot blasting is not required, so the manufacturing process can be simplified and costs can be reduced. Such an effect is more remarkably exhibited when the outer diameter surface has a ground surface roughness Rmax = 4s to 10s.
