この考案は、オイルシールに用いるリップ反転防止のためのプロテクタに関す るものである。 This idea is related to a protector used for oil seals to prevent lip inversion. It is something that
【０００２】0002
一般に、オイルシールのリップの内側に軸を挿入する際に、軸の先端でリップ 上端を押圧することによりリップを内側に反転させてしまう不具合が 10000回に 数回程度ある。 Generally, when inserting the shaft inside the lip of the oil seal, the tip of the shaft will Fixed an issue where the lip would flip inward by pressing the top edge 10,000 times. A few times.
【０００３】 そのため従来、金属補強環の外周部の外面をハウジングに嵌合するタイプの外 周金属嵌合型オイルシールにおいては、図４に示すように外周部の内面を均等な 円筒面に成形し、その内周側に断面Ｌ型のプロテクタを圧入嵌合するようにした もの、図５に示すようにプロテクタの外周部を内周側に縮径するようにテーパー 状とし、プロテクタの内側に圧入嵌合した後にオイルシールの外周部の上端を内 側に折曲してカシメるようにしたもの、図６に示すようにハウジングに嵌合し易 くするために、外周部の先端が内側に屈曲したオイルシールの場合には、その外 周部の外周に断面Ｌ型のプロテクタを圧入嵌合するようにしたものが知られてい る。0003 Therefore, conventionally, the outer surface of the outer periphery of the metal reinforcing ring was fitted into the housing. In a circumferential metal fitting type oil seal, the inner surface of the outer periphery is evenly spaced as shown in Figure 4. It is molded into a cylindrical surface, and a protector with an L-shaped cross section is press-fitted onto the inner circumference. The protector is tapered so that the outer circumference of the protector is reduced in diameter as shown in Figure 5. After press-fitting the oil seal inside the protector, insert the upper edge of the outer periphery of the oil seal inside the protector. It is bent to the side and crimped, and can be easily fitted into the housing as shown in Figure 6. In the case of an oil seal with the tip of the outer periphery bent inward in order to It is known that a protector having an L-shaped cross section is press-fitted onto the outer periphery of the peripheral part. Ru.
【０００４】 しかしながら、いずれもオイルシールの補強環の外周部にプロテクタの外周部 を圧入嵌合し、オイルシールをハウジングに嵌合するときに相互の外周部が一体 となってハウジングに圧入することになるため、総体的に外周部の剛性が大きく なり、ハウジングに嵌合するための圧入荷重が高くなって、ハウジングへの嵌合 が極めて困難になるという欠点があった。0004 However, in both cases, the outer periphery of the protector is attached to the outer periphery of the reinforcing ring of the oil seal. press fit, and when fitting the oil seal to the housing, the outer peripheries of each other become one piece. Since it is press-fitted into the housing, the overall rigidity of the outer periphery is large. This increases the press-fitting load for fitting into the housing, making it difficult to fit into the housing. The drawback was that it was extremely difficult.
【０００５】 また、ハウジングがアルミニウムのような熱膨張の高い材質で、プロテクタ及 びオイルシールの補強環を普通鋼で成形した場合には、ハウジングへの嵌合と同 時に嵌合代が低下すると共に、高温下でハウジングが膨張するとき、補強環の外 周部及びプロテクタがこの膨張に追従できず、オイルシールのハウジングへの嵌 合が緩んでオイル洩れを生じ、またプロテクタもオイルシールから抜けてしまう という問題があった。[0005] In addition, if the housing is made of a material with high thermal expansion such as aluminum, the protector and If the reinforcing ring of the oil seal and oil seal is made of ordinary steel, it will fit in the same way as the housing. When the mating allowance decreases and the housing expands at high temperatures, the outside of the reinforcing ring The surrounding part and protector cannot follow this expansion, causing the oil seal to fit into the housing. The seal becomes loose, causing oil leakage, and the protector also comes off from the oil seal. There was a problem.

この考案は、従来のプロテクタにおける外周金属嵌合型オイルシールの外周部 の剛性を増大させ、またハウジングがアルミニウムのような熱膨張の高い材質で ある場合にオイルシールから脱落するという課題を解決することにある。 This idea is based on the outer periphery of the outer periphery metal fitting type oil seal in conventional protectors. The rigidity of the housing is increased, and the housing is made of a material with high thermal expansion such as aluminum. The purpose is to solve the problem of oil seals falling off in certain cases.

オイルシールの補強環の外周部よりも小径の円筒状周壁の上端に内周側に張出 した環状板を設け、この円筒状周壁の下端に外周側に斜め上向きに突設した係止 片を、円筒状周壁の外周に環状に、または周方向に所要間隙を介して複数区分し て設けたオイルシール用プロテクタを提案するものである。 The reinforcing ring of the oil seal protrudes toward the inner periphery at the upper end of the cylindrical peripheral wall with a smaller diameter than the outer periphery. A locking plate is provided on the lower end of this cylindrical peripheral wall and protrudes diagonally upward on the outer peripheral side. The pieces are divided annularly around the outer periphery of the cylindrical peripheral wall or into multiple sections with required gaps in the circumferential direction.

外周金属嵌合型オイルシールの外周部の内側にプロテクタを圧入するとき、係 止片が圧入方向に縮径するテーパー状を成しているため、嵌入し易く、しかも係 止片の弾性変形と筒状周壁の弾性変形によりオイルシールの外周部の下部に容易 に圧入嵌合され、その先端で弾性圧着して係止される。 When press-fitting the protector inside the outer periphery of the outer periphery metal fitting type oil seal, the The retaining piece has a tapered shape that reduces in diameter in the press-fitting direction, making it easy to fit and keep it engaged. Due to the elastic deformation of the stopper and the cylindrical peripheral wall, it can be easily attached to the lower part of the outer periphery of the oil seal. It is press-fitted into the body, and the tip is elastically crimped and locked.
【０００９】 この状態において、係止片はオイルシールの外周部の下部（水平環状部との付 根付近）においてその先端で弾性圧着しているため、オイルシールの外周部の剛 性をほとんど増すことなくオイルシールをハウジングに容易に嵌合することが可 能となり、またハウジングが熱膨張により拡径し、これにオイルシールが追従し て拡径しても、係止片の弾性によりこれに追従して圧着を維持し、しかも係止片 はオイルシールの外周部に楔状に圧入されて抜け方向には抜け難くなっているた め、着実に係止されて脱落しない。[0009] In this state, the locking piece is attached to the lower part of the outer circumference of the oil seal (where it connects with the horizontal annular part). Because the tip is elastically crimped (near the root), the rigidity of the outer periphery of the oil seal is reduced. The oil seal can be easily fitted into the housing with little increase in performance. The housing expands in diameter due to thermal expansion, and the oil seal follows this. Even if the diameter is expanded by the locking piece, the elasticity of the locking piece will follow this and maintain the crimping. is press-fitted into the outer periphery of the oil seal in a wedge shape, making it difficult to remove in the removal direction. Therefore, it is securely locked and does not fall off.
【００１０】 次に、シールすべき軸をプロテクタの軸挿通孔の内側に挿入すると、その周縁 において挿入方向に案内され、オイルシールのリップを反転することなく確実に 挿入される。0010 Next, when the shaft to be sealed is inserted inside the shaft insertion hole of the protector, its periphery is guided in the insertion direction, ensuring that the lip of the oil seal does not turn over. inserted.

鋼板等の薄肉金属板からなるプロテクタ１は、外周金属嵌合型オイルシール２ の補強環の外周部３よりも外径の小さい円筒状周壁１ａと、この円筒状周壁１ａ の上端に内周側にフランジ状に張出した中心部に軸挿通孔４を有する環状板１ｂ と、筒状周壁１ａの下端に外周側に斜め上向きに突設した係止片１ｃとから一体 に成形されている。 A protector 1 made of a thin metal plate such as a steel plate has an outer periphery metal fitting type oil seal 2. A cylindrical peripheral wall 1a having an outer diameter smaller than the outer peripheral part 3 of the reinforcing ring, and this cylindrical peripheral wall 1a. An annular plate 1b having a shaft insertion hole 4 in the center extending in the shape of a flange toward the inner circumference at the upper end. and a locking piece 1c that projects obliquely upward on the outer circumferential side from the lower end of the cylindrical peripheral wall 1a. It is molded into.
【００１２】 係止片１ｃは、図２に示すように円筒状周壁１ａの周方向に一連の環状に形成 するか、あるいは図３に示すように円筒状周壁１ａの周方向に所要間隙５を介し て複数に区分して設け、その先端の外径は補強環の外周部３の内径より若干大き く形成されている。0012 The locking pieces 1c are formed in a series of annular shapes in the circumferential direction of the cylindrical peripheral wall 1a, as shown in FIG. Alternatively, as shown in FIG. The outer diameter of the tip is slightly larger than the inner diameter of the outer peripheral part 3 of the reinforcing ring. It is well formed.
【００１３】 なお、間隙５は、係止片１ｃをより弾性変形し易くするために、係止片１ｃ， １ｃ間のみならずこれに連続して円筒状周壁１ａに設けてもよい。[0013] Note that the gap 5 is formed between the locking pieces 1c and 1c in order to make it easier to elastically deform the locking pieces 1c. It may be provided not only between 1c but also continuously on the cylindrical peripheral wall 1a.
【００１４】 また、円筒状周壁１ａと環状板１ｂの交差部付近にはオイル抜き孔を設けても よい。[0014] Also, an oil drain hole may be provided near the intersection of the cylindrical peripheral wall 1a and the annular plate 1b. good.
【００１５】 上記プロテクタ１を装着する外周金属嵌合型オイルシール２の補強環は図１に 示すように、鋼板等の金属板により断面ほぼＬ型等の環状に成形され、必要に応 じてその成形後において軟窒化処理、オーステンパー処理等の硬化処理が施され 、機材の強度及び硬度を高めて弾性限界値（バネ性）が増大されており、筒状の 外周部３の基端からその内側にほぼ水平に張出す水平部６が設けられ、その内周 縁部には、ふっ素ゴムなどの耐熱性ゴム等からなるシールリップ７が形成されて いる。[0015] The reinforcing ring of the outer metal fitting type oil seal 2 to which the protector 1 is attached is shown in Figure 1. As shown in the figure, a metal plate such as a steel plate is formed into an annular shape with an approximately L-shape in cross section. After forming, hardening treatments such as nitrocarburizing and austempering are applied. , the elastic limit value (springiness) has been increased by increasing the strength and hardness of the material, and the cylindrical A horizontal portion 6 is provided that extends almost horizontally from the base end of the outer peripheral portion 3 to the inside thereof, and the inner periphery thereof A seal lip 7 made of heat-resistant rubber such as fluororubber is formed on the edge. There is.
【００１６】 上記構成のプロテクタ１の装着に際しては、オイルシール補強環の外周部３の 内側にプロテクタ１の係止片１ｃを圧入する。[0016] When installing the protector 1 with the above configuration, the outer circumferential portion 3 of the oil seal reinforcing ring should be Press fit the locking piece 1c of the protector 1 inside.
【００１７】 このとき係止片１ｃが圧入方向に縮径するテーパー状を成しているため、オイ ルシール補強環の外周部３に円滑に圧入することができ、しかも係止片１ｃの弾 性変形と筒状周壁１ａの弾性変形により外周部３の下部に容易に圧入嵌合され、 その先端で弾性圧着して係止される。[0017] At this time, since the locking piece 1c has a tapered shape that decreases in diameter in the press-fitting direction, the oil It can be press-fitted smoothly into the outer peripheral part 3 of the Lucille reinforcing ring, and the locking piece 1c is elastic. Due to the elastic deformation and the elastic deformation of the cylindrical peripheral wall 1a, it is easily press-fitted into the lower part of the outer peripheral part 3, The tip is elastically crimped and locked.
【００１８】 この状態において、係止片１ｃはオイルシール補強環の外周部３の下部（水平 環状部との付根付近）においてその先端で弾性圧着しているため、外周部３の剛 性をほとんど増すことなくオイルシール２をハウジングに容易に嵌合することが 可能となり、またハウジングが熱膨張により拡径し、これにオイルシール補強環 の外周部３が追従して拡径しても、係止片１ｃの弾性によりこれに追従して圧着 を維持し、しかも係止片１ｃは外周部３に楔状に圧入されて抜け方向には抜け難 くなっているため、着実に係止されて脱落しない。[0018] In this state, the locking piece 1c is attached to the lower part (horizontal) of the outer peripheral part 3 of the oil seal reinforcing ring. Because it is elastically crimped at its tip (near the root of the annular part), the rigidity of the outer peripheral part 3 is reduced. The oil seal 2 can be easily fitted into the housing with almost no increase in performance. The housing expands in diameter due to thermal expansion, and an oil seal reinforcing ring is added to the housing. Even if the outer peripheral part 3 of Moreover, the locking piece 1c is press-fitted into the outer peripheral part 3 in a wedge shape, making it difficult to remove in the removal direction. Because of this, it is securely locked and does not fall off.
【００１９】 更に、係止片１ｃを筒状周壁１ａの周方向に所要間隙５を介して複数設けた場 合には、係止片１ｃがより弾性変形し易くなり、外周部３の内側に装着すること が容易となる。[0019] Furthermore, if a plurality of locking pieces 1c are provided in the circumferential direction of the cylindrical peripheral wall 1a with a required gap 5 therebetween, In this case, the locking piece 1c becomes more elastically deformable and cannot be attached to the inside of the outer peripheral part 3. becomes easier.
【００２０】 軸挿入孔４の周縁は、プロテクタ１をオイルシール２に装着した状態でシール リップ７の上方に位置するように設定されている。[0020] The periphery of the shaft insertion hole 4 is sealed when the protector 1 is attached to the oil seal 2. It is set to be located above the lip 7.
【００２１】 なお、この考案のプロテクタ１は外周金属嵌合型オイルシールのみならず、外 周ゴムタイプのオイルシールにも装着使用できることはいうまでもない。[0021] In addition, the protector 1 of this invention is not only suitable for external metal fitting type oil seals, but also for external metal fitting type oil seals. Needless to say, it can also be attached to a circumferential rubber type oil seal.
【００２２】[0022]
【考案の効果】 以上の通りこの考案によれば、オイルシールの外周部の内側にプロテクタを圧 入するとき、係止片が圧入方向に縮径するテーパー状を成しているため、嵌入し 易く、しかも係止片の弾性変形と筒状周壁の弾性変形によりオイルシールの外周 部の下部に容易に圧入嵌合され、その先端で弾性圧着して容易に脱落すること無 く着実に係止することができる。[Effect of the idea] As described above, according to this invention, the protector is pressed inside the outer periphery of the oil seal. When inserted, the locking piece has a tapered shape that reduces in diameter in the press-fit direction, so it will not fit easily. The outer periphery of the oil seal is It is easily press-fitted to the bottom of the part, and the tip is elastically crimped to prevent it from falling off easily. It can be locked securely.
【００２３】 そしてこの状態において、係止片はオイルシールの外周部の下部においてその 先端で弾性圧着しているため、外周金属嵌合型オイルシールの場合、その外周部 の剛性をほとんど増すことなくオイルシールをハウジングに容易に嵌合すること が可能となり、またハウジングが熱膨張により拡径し、これにオイルシールが追 従して拡径しても、係止片の弾性によりこれに追従して圧着を維持し、しかも係 止片はオイルシールの外周部に楔状に圧入されて抜け方向には抜け難くなってい るため、着実に係止されて脱落しない。[0023] In this state, the locking piece is located at the bottom of the outer periphery of the oil seal. Since the tip is elastically crimped, in the case of a metal-fitting type oil seal, the outer periphery The oil seal can be easily fitted into the housing without increasing the rigidity of the housing. The housing expands in diameter due to thermal expansion, and an oil seal is added to it. Therefore, even if the diameter expands, the elasticity of the locking piece will follow this and maintain the crimping, and the locking The stopper is press-fitted into the outer periphery of the oil seal in a wedge shape, making it difficult to remove in the removal direction. Because of this, it is securely locked and does not fall off.
【００２４】 更に、係止片を筒状周壁の周方向に所要間隙を介して複数設けた場合には、係 止片がより弾性変形し易くなり、プロテクタのオイルシールへの圧入が容易とな る。[0024] Furthermore, when a plurality of locking pieces are provided with a required gap in the circumferential direction of the cylindrical peripheral wall, the locking pieces The stop piece becomes more elastically deformable, making it easier to press fit into the protector's oil seal.
