機などに使用される低速の非分離形アンギュラ玉軸受に
関するものである。DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a low-speed non-separable angular contact ball bearing used in a traveling hydraulic speed reducer of a power shovel of a construction machine.
「従来の技術」 アンギュラ玉軸受は外輪を加熱し、熱膨張させて組立て
るので深みぞ玉軸受と同じ大きさの玉を数多く組込むこ
とができる。"Prior Art" Angular contact ball bearings are assembled by heating the outer ring and thermal expansion, so many balls of the same size as deep groove ball bearings can be incorporated.

毎にポケツトが打抜き成形されたプレスわん形保持器
３、あるいは第１１図に示す如き銅合金リングより工作
機械にてボール用ポケツトが穿孔されたもみ抜き保持器
３１を介して複数の玉４が組込まれることもよく知られ
ている。For example, as shown in FIG. 10, a press cage retainer 3 in which pockets are punched at predetermined intervals between the inner and outer rings 1, 2 or a copper alloy ring as shown in FIG. It is also well known that a plurality of balls 4 are incorporated through a machined cage 31 having a hole.
また、第８図に示す如き、内外輪１，２に円周方向隙間
を玉径１ケ分以下に小さくすることにより保持器を使用
しない玉４のみの総玉入れアンギュラ玉軸受が知られて
いる。Further, as shown in FIG. 8, there is known an all-in-one angular contact ball bearing having only a ball 4 without using a cage by reducing the circumferential clearance between the inner and outer rings 1 and 2 to a ball diameter of 1 or less. There is.
これらアンギュラ玉軸受はラジアル荷重と一方向スラス
ト荷重を負荷することができる特徴を有する。These angular contact ball bearings have the feature of being able to apply radial loads and unidirectional thrust loads.
また、深みぞ玉軸受、旋回輪軸受などで間隔体を用いた
軸受が知られている。In addition, bearings using a spacer are known, such as deep groove ball bearings and slewing ring bearings.
該軸受は第９図に示すように、外輪２に玉４および間隔
体５を挿入する入れ穴２１が形成され、該入れ穴２１を
介して玉４および間隔体５が順次挿入された後、スロツ
トぶた６が嵌め込まれている。As shown in FIG. 9, the bearing is formed with an insertion hole 21 into which the balls 4 and the spacer 5 are inserted in the outer ring 2, and after the balls 4 and the spacer 5 are sequentially inserted through the insertion hole 21, The slot lid 6 is fitted.
「考案が解決しようとする問題点」 ところが、鋼板をプレスにてポケツト打抜き成形してな
る保持器を組込むため、量産に適しているが、金型など
を要するためコスト高になる。"Problems to be solved by the invention" However, it is suitable for mass production because it incorporates a cage formed by punching and punching a steel plate with a press, but it requires a metal mold and the like, which increases the cost.
また銅合金リングを工作機械、例えばボール盤たてポケ
ツトが１ケづつ穿孔するため、金型などを必要としない
が、量産に適せず、かつ高価な肉厚材料を使用するため
コスト高要因の１つになっている。In addition, since a copper alloy ring is machined, for example, by a drilling machine with one pocket each, no mold is required, but it is not suitable for mass production, and the use of an expensive thick material causes a high cost factor. It is one.
また、保持器を使用しない総玉入れアンギュラ玉軸受は
回転中の玉相互間のかじり作用が起き、好ましくない。Further, a full-ball-insertion angular contact ball bearing that does not use a retainer is not preferable because it causes a galling effect between the rotating balls.
また、外輪に入れ穴を形成し、該入れ穴を介して玉およ
び間隔体を順次挿入するようなことは構造並びに作業工
程上コスト高となる。Further, forming the insertion hole in the outer ring and sequentially inserting the balls and the spacers through the insertion hole increases the cost in terms of the structure and the working process.
これら、コスト高要因となる保持器の製作、加工あるい

特徴とする非分離形アンギュラ玉軸受を提供することに
ある。"Means for Solving Problems" The present invention has the following technical means for solving the above problems.
That is, in an angular ball bearing that has a plurality of balls between the inner and outer rings, and a spacing body is arranged between the balls, in the opening of the inner and outer rings, a ball and a spacing body insertion groove or an outer ring. No insertion hole is formed on the side, the outer diameter dimension B of the spacer is slightly smaller than the diameter dimension D of the balls, is larger than the opening dimension A of the inner and outer races, and both of the inner and outer races or the inner and outer races are It is an object of the present invention to provide a non-separable angular contact ball bearing, characterized in that a barb is provided on either one of them.
「作用」 本考案は上記せる如き構成要件を具備することにより、
間隔体の外径寸法が玉の外径寸法より僅かに小さく、か

ぐ抜け出し防止機能並びに玉と玉間の接触を防ぐと同時
に所定間隔に保持する機能を有する。"Operation" The present invention has the above-mentioned constitutional requirements,
Since the outer diameter of the spacing body is slightly smaller than the outer diameter of the ball and the diameter of the spacing body is larger than the opening between the inner and outer rings, the spacing body falls off from the balls and the balls and the inner and outer rings. It has a function to prevent slipping out and a function to prevent contact between balls and at the same time hold it at a predetermined interval.
また、間隔体軸受は第１０図のプレス保持器、第１１図
のもみ抜き保持器のような保持器がないので、荷重負荷
部の肩を高くすることができ、大きなスラスト荷重を負
荷する場合に、制約されない利点がある。In addition, since the spacer bearing does not have a retainer such as the press retainer shown in FIG. 10 and the machined retainer shown in FIG. 11, it is possible to increase the shoulder of the load-bearing portion and to apply a large thrust load. Has the advantage of not being constrained.
