Description
【0001】[0001]
この考案は、自動車エンジンに使用されるタイミングベルトや、補機用駆動ベ ルトに張力を与えるためのテンショナ、あるいはアイドラ等に使用されるプーリ 装置に関する。 The present invention relates to a timing belt used in an automobile engine, a tensioner for applying tension to a drive belt for auxiliary equipment, or a pulley device used for an idler or the like.
【0002】[0002]
この種のプーリ装置において、特に自動車エンジンの補機駆動ベルトテンショ ナは、外部から直接に水が掛かったりするため、軸受内部への水の浸入が問題と なることがある。 従来、これを防止するため、図11に示すように軸受カバーを設けたものが提 案されている。プーリ50は、一対の分割プーリ51,51からなり、その軸受 圧入部51aに軸受52が圧入されている。軸受52は、ゴム製のシール付きの 深溝玉軸受からなり、シール53は軸受外輪55のシール取付溝に取付けられて 内輪54のシール溝に摺接する。内輪54には軸56が圧入される。軸受カバー 57は、プーリ50の軸受圧入部51aの外周に圧入されて軸受52の側面を覆 うリング板状としてある。このように軸受カバー57を設けることにより、外部 から直接に水が軸受52にかかることが防止される。なお、軸受カバー57はプ ーリ50に一体に形成する場合もある。 In this type of pulley device, particularly in the case of an accessory drive belt tensioner of an automobile engine, water may be directly splashed from the outside, so that water intrusion into the bearing may be a problem. Conventionally, in order to prevent this, a bearing provided with a bearing cover as shown in FIG. 11 has been proposed. The pulley 50 includes a pair of split pulleys 51, 51, and a bearing 52 is press-fitted into the bearing press-fitting portion 51a. The bearing 52 is a deep groove ball bearing with a rubber seal, and the seal 53 is mounted in a seal mounting groove of a bearing outer ring 55 and slidably contacts a seal groove of an inner ring 54. A shaft 56 is press-fitted into the inner ring 54. The bearing cover 57 is in the form of a ring plate press-fitted onto the outer periphery of the bearing press-fitting portion 51 a of the pulley 50 to cover the side surface of the bearing 52. By providing the bearing cover 57 in this manner, it is possible to prevent water from directly splashing on the bearing 52 from the outside. The bearing cover 57 may be formed integrally with the pulley 50.
【0003】[0003]
軸受カバー57は、プーリ50と共に回転するものであるため、軸受内輪54 との間に隙間dを有しており、この隙間dから軸受カバー57内に水が入ること がある。このように軸受カバー57内に一旦入った水は、回転しても外部に出に くく、軸受52と軸受カバー57との間の空間に長期間溜まり易い。このように 水が溜まると、プーリ50や軸受52に錆を発生させる原因となり、またシール 53を通って軸受52の内部に水が浸入する可能性がある。特に、軸受内輪54 のシール溝に発生する錆は、シール53のゴム製リップ部の摩耗を促進させ、軸 受寿命の低下につながり易い。 Since the bearing cover 57 rotates together with the pulley 50, there is a gap d between the bearing cover 57 and the bearing inner ring 54, and water may enter the bearing cover 57 through the gap d. As described above, the water once entering the bearing cover 57 is hard to come out to the outside even if it rotates, and is likely to accumulate in the space between the bearing 52 and the bearing cover 57 for a long period of time. Such water accumulation may cause rust in the pulley 50 and the bearing 52, and may cause water to penetrate into the bearing 52 through the seal 53. In particular, rust generated in the seal groove of the bearing inner ring 54 promotes wear of the rubber lip portion of the seal 53, which tends to reduce the bearing life.
【0004】 この考案の目的は、プーリ内に水等が入り難くて排出され易く、軸受内への水 等の侵入防止と、軸受やプーリの防錆が図れ、軸受寿命を向上させることのでき るプーリ装置を提供することである。The object of the present invention is to prevent water, etc. from entering the pulley easily and to discharge it, prevent water from entering the bearing, prevent rusting of the bearing and pulley, and improve bearing life. It is to provide a pulley device.

この考案のプーリ装置は、プーリを支持する転がり軸受の側面を覆う軸受カバ ーを設け、この軸受カバーに出張り部を設け、この出張り部の頂部を除く面に、 カバー内外に開通する窓を設けたものである。 The pulley device of the present invention is provided with a bearing cover that covers the side surface of a rolling bearing that supports the pulley, a protrusion portion is provided on the bearing cover, and a window that opens to the inside and outside of the cover is provided on the surface excluding the top portion of the protrusion portion. Is provided.
【0006】[0006]
この構成によると、軸受に直接に飛水や塵埃等がかかることが軸受カバーによ って防止され、かつその窓によって次のように排水機能が得られる。すなわち、 停止時において、軸受カバー内に浸入した水等は窓から流れ落ちて排出され、プ ーリ内に溜まる水等を最小限にできる。また、回転中は、停止時に軸受カバー内 に溜まった水や、回転中に軸受カバーの内径部等から浸入した水等が、遠心力で 窓から外部に排出される。このように軸受カバー内に水等が溜まることが防止さ れるため、軸受内部への水の浸入が防げ、溜まった水等でプーリや軸受に錆を発 生させることが防止される。 軸受カバーに窓が明いていても、回転中は、掛かった水等が軸受カバーで振り 飛ばされるため、窓から軸受カバー内に浸入しない。この場合に、前記の窓は、 軸受カバーに出張り部を形成してその頂部を除く面に設けたため、回転中におけ る窓からの水の浸入がより一層行われ難くなる。また、このように出張り部の頂 部を除く面に窓が配置されるため、停止中における飛水の浸入も行われ難くなる 。 With this configuration, the bearing cover prevents the bearing from being directly splashed with water or dust, and the window provides the drainage function as follows. That is, at the time of stoppage, water and the like that have entered the bearing cover flow down through the window and are discharged, so that water and the like that accumulate in the pool can be minimized. Also, during rotation, water that has accumulated inside the bearing cover when stopped and water that has entered from the inner diameter of the bearing cover during rotation is discharged to the outside from the window by centrifugal force. In this way, water and the like are prevented from accumulating inside the bearing cover, so that it is possible to prevent water from entering the bearing and prevent the accumulated water and the like from rusting the pulley and the bearing. Even if the window is bright on the bearing cover, the water will not splash into the bearing cover from the window because the splashed water is splashed off by the bearing cover during rotation. In this case, since the window is formed on the surface of the bearing cover excluding the top portion of the bearing cover, it is more difficult for water to enter from the window during rotation. In addition, since the window is arranged on the surface of the projecting part excluding the top part, it is difficult for the water to enter while the vehicle is stopped.

この考案の一実施例を図1および図2に基づいて説明する。このプーリ装置は 、プーリ1を支持する軸受2の両側面を各々覆う一対の軸受カバー15,15を 設け、各軸受カバー15に出張り部16を設けると共に、この出張り部16に窓 17を設けたものである。軸受2はシール付きの深溝玉軸受からなり、内輪5と 外輪6の間に保持器7で保持された転動体8を介在させ、外輪6にシール9を取 付けてある。シール9は芯金にゴム被覆を設けたものであり、そのリップ部を内 輪5のシール溝10に接触させてある。 An embodiment of this invention will be described with reference to FIGS. This pulley device is provided with a pair of bearing covers 15 and 15 that respectively cover both side surfaces of a bearing 2 that supports the pulley 1. Each bearing cover 15 is provided with a projecting portion 16, and a window 17 is provided in the projecting portion 16. It is provided. The bearing 2 is a deep groove ball bearing with a seal, a rolling element 8 held by a cage 7 is interposed between an inner ring 5 and an outer ring 6, and a seal 9 is attached to the outer ring 6. The seal 9 is a core metal provided with a rubber coating, and its lip portion is in contact with the seal groove 10 of the inner ring 5.
【0008】 プーリ1は、互いに対称な一対の分割プーリ1A,1Aで構成される。各分割 プーリ1Aは、円筒状に各々形成された外周側のベルト掛け部1a、内周側の軸 受圧入部1b、および側板部1cからなり、両分割プーリ1A,1Aは側板部1 cでリベット11により互いに固定されている。またプーリ1は、両分割プーリ 1A,1Aにわたって軸受圧入部1bに軸受外輪6を圧入させることで、軸受2 に固定してある。 軸受カバー15はプーリ1と別体に設けたものであり、プーリ1の軸受圧入部 1bの外周に圧入される周壁部15aと、軸受2の側面を覆う側板部15bとで なるリング状に形成してある。側板部15bの内径は、軸受内輪5の外径面と同 程度の寸法としてある。The pulley 1 is composed of a pair of split pulleys 1A, 1A which are symmetrical to each other. Each of the split pulleys 1A comprises a belt-engaging portion 1a on the outer peripheral side formed in a cylindrical shape, a shaft pressure receiving portion 1b on the inner peripheral side, and a side plate portion 1c. Both split pulleys 1A and 1A are side plate portions 1c. They are fixed to each other by rivets 11. Further, the pulley 1 is fixed to the bearing 2 by pressing the bearing outer ring 6 into the bearing press-fitting portion 1b across the split pulleys 1A and 1A. The bearing cover 15 is provided separately from the pulley 1, and is formed in a ring shape including a peripheral wall portion 15a that is press-fitted to the outer periphery of the bearing press-fitting portion 1b of the pulley 1 and a side plate portion 15b that covers the side surface of the bearing 2. I am doing it. The inner diameter of the side plate portion 15b is approximately the same as the outer diameter surface of the bearing inner ring 5.
【0009】 軸受カバー15の出張り部16は周方向の4箇所に設けてある。各出張り部1 6は、内面が円弧溝状の凹み部となったリブ状のものであり、側板部15bの外 周部から周壁部15aの幅方向中間部まで延びて設けられ、その先端に窓17が 形成されている。軸受カバー15およびプーリ1の材質は、金属板であっても、 樹脂成形品であっても良い。なお、図1(A)は、ボルト孔13を有する軸14 を軸受内輪2に圧入により固定した状態を示す。The protrusions 16 of the bearing cover 15 are provided at four locations in the circumferential direction. Each of the protrusions 16 has a rib shape whose inner surface is a recess in the shape of an arc groove, and is provided so as to extend from the outer peripheral portion of the side plate portion 15b to the middle portion in the width direction of the peripheral wall portion 15a, and its tip end. A window 17 is formed in the. The material of the bearing cover 15 and the pulley 1 may be a metal plate or a resin molded product. 1A shows a state in which the shaft 14 having the bolt holes 13 is fixed to the bearing inner ring 2 by press fitting.
【0010】 この構成によると、軸受2に直接に飛水や塵埃等がかかることが軸受カバー1 5によって防止され、かつその窓17によって次のように排水機能が得られる。 すなわち、停止時において、軸受カバー15内の軸受2との隙間に浸入した水等 は、下側に位置する窓17から流れ落ちて排出され、プーリ1内に溜まる水等を 最小限にできる。また、回転中は、停止時に軸受カバー15内に溜まった水や、 回転中に軸受カバー15の内径部等から浸入した水等が、遠心力で窓17から外 部に排出される。図1(B)の矢印aは、この水の浸入および排出経路を示す。According to this structure, the bearing cover 15 prevents the bearing 2 from being directly splashed with water or dust, and the window 17 of the bearing cover 15 provides a drainage function as follows. That is, at the time of stoppage, water and the like that have entered the gap between the bearing 2 and the bearing 2 in the bearing cover 15 flow down and are discharged from the window 17 located on the lower side, and the water and the like that accumulate in the pulley 1 can be minimized. Further, during rotation, water accumulated inside the bearing cover 15 at the time of stop, water that has entered from the inner diameter portion of the bearing cover 15 during rotation, and the like are discharged to the outside from the window 17 by centrifugal force. The arrow a in FIG. 1 (B) shows the infiltration and discharge paths of this water.
【0011】 このように軸受カバー15内に水等が溜まることが防止されるため、軸受2の 内部への水等の浸入が防げ、プーリ1や軸受2に錆を発生させることが防止され る。特に、シール溝10の錆の発生が防止されることから、シール9の摩耗が生 じ難くなる。これらにより、軸受2の寿命が向上する。 軸受カバー15に窓が明いていても、回転中は、かかった水等が軸受カバー1 5で振り飛ばされるため、窓4から軸受カバー15内に浸入しない。しかも、窓 17は、軸受カバー15に形成された出張り部16のプーリ奥側の端部に設けら れているため、回転時および停止時のいずれにおいても、窓17からの水等の浸 入が生じ難い。すなわち、前記のように出張り部16に窓17を設けたため、水 等が外部から入り難く、しかも排出は良好に行われる。 また、この実施例では軸受カバー15をプーリ1と別体に設ける構成としたた め、軸受カバー15を有しない従来形式のプーリ装置と各部品を共用することが でき、部品共通化による生産性の向上が図れる。As described above, since water and the like are prevented from accumulating in the bearing cover 15, it is possible to prevent water and the like from entering the inside of the bearing 2 and prevent rust from occurring in the pulley 1 and the bearing 2. . In particular, since the rusting of the seal groove 10 is prevented, the seal 9 is less likely to be worn. As a result, the life of the bearing 2 is improved. Even if the bearing cover 15 has a bright window, the water and the like splashed by the bearing cover 15 are prevented from entering the bearing cover 15 through the window 4 during rotation. Moreover, since the window 17 is provided at the end of the protruding portion 16 formed on the bearing cover 15 on the inner side of the pulley, the water is prevented from seeping through the window 17 both during rotation and when stopped. It is hard to get in. That is, since the window 17 is provided in the projecting portion 16 as described above, it is difficult for water and the like to enter from the outside, and the water is discharged well. In addition, since the bearing cover 15 is provided separately from the pulley 1 in this embodiment, each component can be shared with a conventional pulley device that does not have the bearing cover 15, and productivity can be improved by sharing the components. Can be improved.
【0012】 なお、軸受カバー15の出張り部16は図3の例のように周壁部15aの端部 まで続けて設け、その内側の溝端部を窓17としても良い。このように出張り部 17を長く形成した場合も、プーリ1への取付状態で軸受カバー15の周壁部1 5aの先端とプーリ1の側壁部1cとが離れていれば、窓17からの排水が行え る。The protruding portion 16 of the bearing cover 15 may be continuously provided up to the end portion of the peripheral wall portion 15a as in the example of FIG. 3, and the groove end portion inside thereof may be used as the window 17. Even when the protruding portion 17 is formed to be long in this way, if the tip of the peripheral wall portion 15a of the bearing cover 15 and the side wall portion 1c of the pulley 1 are separated from each other when mounted on the pulley 1, drainage from the window 17 Can be done.
【0013】 また、前記実施例では軸受カバー15をプーリ1と別体に形成したが、図4に 示すようにプーリ1の軸受圧入部1bから一体に続けて、軸受2の側面を覆うよ うに軸受カバー1dを設けても良い。軸受カバー1dには図1,図2の実施例と 同様に出張り部16を設け、その先端に窓17を設ける。このように軸受カバー 1dをプーリ1に一体に形成した場合は、プーリ装置の部品点数が削減される。Further, in the above embodiment, the bearing cover 15 is formed separately from the pulley 1, but as shown in FIG. 4, the bearing press-fitting portion 1b of the pulley 1 is integrally continued to cover the side surface of the bearing 2. The bearing cover 1d may be provided. The bearing cover 1d is provided with a projecting portion 16 and a window 17 is provided at the tip thereof as in the embodiment shown in FIGS. When the bearing cover 1d is formed integrally with the pulley 1 as described above, the number of parts of the pulley device is reduced.
【0014】 図5および図6はさらに他の実施例を示す。この例は、プーリ1と別体の軸受 カバー15に設けた出張り部19を、側板部15bの外周部から周壁部15aに 渡って形成した橋状の切抜き片で構成したものである。出張り部19は両端が軸 受カバー15に繋がっており、両側面が窓20となる。出張り部19は、図7の ように軸受カバー15の周壁部15a側の端部が周壁部15aから離れた形状と しても良い。 これらの構成の場合も、出張り部19が設けられてその側面に窓20が開口す るため、窓20からの水等の浸入が行われ難くなる。5 and 6 show still another embodiment. In this example, the projecting portion 19 provided on the bearing cover 15 that is separate from the pulley 1 is configured by a bridge-shaped cutout piece formed from the outer peripheral portion of the side plate portion 15b to the peripheral wall portion 15a. Both ends of the projecting portion 19 are connected to the bearing cover 15, and both side surfaces serve as windows 20. The protruding portion 19 may have a shape in which the end of the bearing cover 15 on the side of the peripheral wall portion 15a is separated from the peripheral wall portion 15a as shown in FIG. Also in the case of these configurations, since the projecting portion 19 is provided and the window 20 is opened on the side surface thereof, infiltration of water or the like through the window 20 becomes difficult.
【0015】 なお、前記の図4の例のように軸受カバー1dをプーリ1と一体に設けたもの において、図6または図7の例のような出張り部19と窓20とを形成しても良 い。In the case where the bearing cover 1d is integrally provided with the pulley 1 as in the example of FIG. 4 described above, the protruding portion 19 and the window 20 as in the example of FIG. 6 or 7 are formed. Is also good.
【0016】 図8および図9はさらに他の実施例を示す。この例は、プーリ1と別体の軸受 カバー15を設けたものにおいて、軸受カバー15の側板部15bに出張り部2 1を設けたものである。出張り部21は、三角錐状の切り起し加工部からなり、 軸受カバー15の外径側の面が窓22となっている。出張り部21は、図10( A)のように曲面板状のものとしても良く、また図10(B)のようにL字状に して平板状の切起片としても良い。 このように出張り部21および窓22を形成した場合も、良好な排水効果を得 ながら、窓22からの水の浸入を生じ難くできる。8 and 9 show still another embodiment. In this example, a bearing cover 15 that is separate from the pulley 1 is provided, and a protrusion 21 is provided on the side plate portion 15b of the bearing cover 15. The protruding portion 21 is formed by a triangular pyramid-shaped cut and raised portion, and the surface of the bearing cover 15 on the outer diameter side is a window 22. The protruding portion 21 may have a curved plate shape as shown in FIG. 10 (A), or may have an L-shaped flat piece as shown in FIG. 10 (B). Even when the protruding portion 21 and the window 22 are formed in this way, it is possible to prevent water from entering through the window 22 while obtaining a good drainage effect.
【0017】 なお、前記の図4の例のように軸受カバー1dをプーリ1と一体に設けたもの において、図9や図10(A),(B)の例のような出張り部21と窓22とを 形成しても良い。In the case where the bearing cover 1d is provided integrally with the pulley 1 as in the example of FIG. 4 described above, a protrusion 21 as in the example of FIGS. 9 and 10A and 10B is provided. The window 22 may be formed.
