Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

この考案は、アンギュラ玉軸受に関し、特にその潤滑構造に関するものである 。 The present invention relates to an angular contact ball bearing, and more particularly to its lubrication structure.

【0002】[0002]

【従来の技術】[Prior art]

各種産業機械に使用されるアンギュラ玉軸受の潤滑は、一般にグリースが用い られるが、グリース漏れ、水の侵入によるグリースの劣化・流出等の問題を生じ ることがある。この対策として、超高分子量ポリオレフィンと潤滑グリースの混 合物からなる固形潤滑剤を用いる場合がある。 Grease is generally used for lubrication of angular contact ball bearings used in various industrial machines, but problems such as grease leakage and grease deterioration / outflow due to water intrusion may occur. As a countermeasure, a solid lubricant made of a mixture of ultra-high molecular weight polyolefin and lubricating grease may be used.

【0003】 図4はその一例であり、1は内輪、2は外輪、3は玉、4は保持器、5は軸受 内部のすき間にすき間なく封入された固形潤滑剤である。FIG. 4 shows an example thereof, in which 1 is an inner ring, 2 is an outer ring, 3 is a ball, 4 is a cage, and 5 is a solid lubricant which is enclosed in a clearance inside the bearing without a gap.

【0004】 この図のように、固形潤滑剤5をすき間なく封入する形式をフルパック型と称 し、部分的に封入する形式をスポットパック型と称する。As shown in this figure, a type in which the solid lubricant 5 is enclosed without gap is called a full pack type, and a type in which the solid lubricant 5 is partially enclosed is called a spot pack type.

【0005】 上記のアンギュラ玉軸受に用いられる保持器4は、図5に示すごときカップ型 である。また、図6に示すごときもみ抜き型の保持器4’を使用する場合もある 。The cage 4 used in the above angular ball bearing is a cup type as shown in FIG. Further, as shown in FIG. 6, a cage type retainer 4'may be used.

【0006】[0006]

【考案が解決しようとする課題】[Problems to be solved by the device]

アンギュラ玉軸受において、固形潤滑剤5をフルパック型式で用いると、摩擦 トルクが大きくなり、dn値(d:軸受内径、n:回転数)はせいぜい5万程度 であり、高速回転に不向きであるという問題がある。 In the angular ball bearing, when the solid lubricant 5 is used in the full pack type, the friction torque becomes large, and the dn value (d: bearing inner diameter, n: rotational speed) is at most about 50,000, which is not suitable for high speed rotation. There is a problem.

【0007】 一方、摩擦トルクを低減するためにスポットパック型式を採用することが考え られるが、従来のアンギュラ玉軸受においては、前述のカップ型保持器4或いは もみ抜き型保持器4’を使用しているため、これらはいずれも玉保持穴6相互間 のすき間が少ないため固形潤滑剤をスポットパックすることは不可能である。こ のため、従来は固形潤滑剤を用いたアンギュラ玉軸受において、高速回転に適し たものは存在しなかった。On the other hand, it may be possible to adopt a spot pack type in order to reduce the friction torque, but in the conventional angular ball bearing, the cup type cage 4 or the chamfered type cage 4 ′ described above is used. Therefore, it is impossible to spot-pack the solid lubricant because the gaps between the ball holding holes 6 are small. For this reason, conventionally, there has been no angular ball bearing using a solid lubricant suitable for high speed rotation.

【0008】 そこで、この考案は保持器に工夫を加えることにより、スポットパック型式の アンギュラ玉軸受を提供することを課題とする。Therefore, it is an object of the present invention to provide a spot pack type angular contact ball bearing by devising a cage.

【0009】[0009]

【課題を解決するための手段】[Means for Solving the Problems]

上記の課題を解決するために、この考案は内輪と外輪との間に保持器により保 持された玉を介在してなるアンギュラ玉軸受において、上記保持器を、玉の保持 部とその保持部に連成された連結部とを一定間隔で環状に設けた2枚の金属板を 相い対向して組合せて構成し、上記保持器の連結部のまわりに固形潤滑剤をスポ ット封入した構成としたものである。 In order to solve the above problems, the present invention relates to an angular ball bearing in which a ball held by a cage is interposed between an inner ring and an outer ring, and the cage is provided with a ball holding portion and a holding portion thereof. And a connecting part connected to each other are formed by combining two metal plates annularly provided at regular intervals so as to face each other, and a solid lubricant is spot-filled around the connecting part of the cage. It is configured.

【0010】[0010]

【作用】[Action]

上記構成のアンギュラ玉軸受は、スポットパックされた固形潤滑剤から滲出す る油分と、グリースとにより潤滑される。固形潤滑剤はスポットパック型式であ るので、低摩擦トルク、低発熱となり、高速性が増す。 The angular contact ball bearing configured as described above is lubricated by the oil leaching from the spot-packed solid lubricant and the grease. Since the solid lubricant is of the spot pack type, it has low friction torque, low heat generation, and high speed.

【0011】[0011]

【実施例】【Example】

図1から図3に示すように、実施例のアンギュラ玉軸受は、内輪1と外輪2と の間に、保持器7によって保持された多数の玉3から成っている。またシール部 材8、8を付ける場合もある。 As shown in FIGS. 1 to 3, the angular ball bearing of the embodiment is composed of a large number of balls 3 held by a cage 7 between an inner ring 1 and an outer ring 2. Also, the seal members 8 and 8 may be attached.

【0012】 保持器7は、2枚の波形金属板9、9の組合せにより構成される。各金属板9 は、玉3の半周に沿う保持部10と、その保持部10の一端に形成された連結部 11を一定間隔をおいて環状に形成したものであり、両方の波形金属板9の保持 部10相互、及び連結部11相互を対向させて、連結部11相互をリベット12 でかしめている。The cage 7 is composed of a combination of two corrugated metal plates 9, 9. Each metal plate 9 is formed by forming a holding portion 10 along a half circumference of the ball 3 and a connecting portion 11 formed at one end of the holding portion 10 in a ring shape with a constant interval. The holding portions 10 and the connecting portions 11 are opposed to each other, and the connecting portions 11 are caulked with the rivets 12.

【0013】 固形潤滑剤5は上記の連結部11のまわりにスポットパックされる。この固形 潤滑剤5は、ポリルーブ、プラスチックグリースの商品名で知られているもので あり、平均分子量約1×106 〜5×106 の超高分子量ポリエチレン95〜1 wt%と、その超高分子量ポリエチレンのゲル化温度より高い滴点を有する潤滑 グリース5〜99wt%とからなる混合物を上記連結部11のまわりに充填した のち、上記超高分子量ポリエチレンのゲル化温度以上に加熱し、その後冷却固化 せしめたものである(特公昭63−23239号公報参照)。The solid lubricant 5 is spot-packed around the connecting portion 11 described above. This solid lubricant 5 is known under the trade name of polylube and plastic grease, and is 95 to 1 wt% of ultrahigh molecular weight polyethylene having an average molecular weight of about 1 × 10 6 to 5 × 10 6 and its ultrahigh content. A mixture consisting of 5 to 99 wt% of lubricating grease having a dropping point higher than the gelling temperature of the high molecular weight polyethylene is filled around the connecting portion 11 and then heated to a temperature higher than the gelling temperature of the ultra high molecular weight polyethylene and then cooled. It has been solidified (see Japanese Patent Publication No. 63-23239).

【0014】 その他の例として、平均分子量約1×106 〜5×106 の超高分子量ポリオ レフィンのゲル化点より高い滴点を有する潤滑グリース5〜99wt%に粒径1 〜100μmの前記超高分子量ポリオレフィン粉末95〜1wt%を混合して前 記ゲル化点以上の温度で分散保持させたものでもよい。As another example, 5 to 99 wt% of lubricating grease having a dropping point higher than the gelation point of an ultrahigh molecular weight polyolefin having an average molecular weight of about 1 × 10 6 to 5 × 10 6 and a particle size of 1 to 100 μm are used. It is also possible to mix 95 to 1 wt% of ultra-high molecular weight polyolefin powder and disperse and hold it at a temperature above the gel point.

【0015】 上記いずれの場合も、固体ワックス等の油の滲み出し抑制添加物を加えること がある。In any of the above cases, an oil exudation suppressing additive such as a solid wax may be added.

【0016】 なお、上記固形潤滑剤5に外の軸受の内部のすき間には、グリースが封入され 、シール部材8、8によりシールされる。Grease is filled in the solid lubricant 5 in the clearance inside the outer bearing, and is sealed by the seal members 8, 8.

【0017】[0017]

【考案の効果】[Effect of device]

この考案のアンギュラ玉軸受は、以上のごときものであるから、固形潤滑剤が 摩擦トルクに与える影響が殆んどないために、dn値は20万程度に達し、高速 性が向上する効果がある。また、固形潤滑剤の分だけグリースの量が少なくなる ため、グリース漏れ等の不都合も少なくなり、メンテナンスが容易になる。 Since the angular contact ball bearing of the present invention is as described above, since the solid lubricant has almost no effect on the friction torque, the dn value reaches about 200,000 and the high speed performance is improved. . In addition, since the amount of grease is reduced by the amount of the solid lubricant, inconveniences such as grease leakage are reduced and maintenance is facilitated.
