The retainer 40 includes a first annular member 50 and a second annular member 55 which are arranged so as to be separated from each other in the axial direction and a plurality of pins which connect the first annular member 50 and the second annular member 55 and are arranged leaving an interval in the circumferential direction. Further, in the rolling bearing 10 formed by penetrating a screw hole 53 for attaching an eye bolt to a first annular member 50 in parallel with the pin, a screw stop 54 is formed on an edge part of the pin side of the screw hole 53 by crushing the edge part.

Description

本発明は、ピンを介してころを回転可能に支持したころ軸受に関する。   The present invention relates to a roller bearing that rotatably supports a roller via a pin.

例えば、図７（特許文献１）に示すようなころ軸受は、中空ころ１３０のピン穴にピン１２０を挿入し、ピン１２０の両端を小径環状部材１０１および大径環状部材１１０に連結している。小径環状部材１０１および大径環状部材１１０にねじ穴１１１が外径側より内径側へ穿孔され、このねじ穴１１１にアイボルト１４０が螺合されている。アイボルト１４０を使ってクレーンによりころ軸受を吊り下げて搬送している。小径環状部材１０１および大径環状部材１１０と、ピン１２０とからなる保持器１００が構成されている。   For example, in a roller bearing as shown in FIG. 7 (Patent Document 1), the pin 120 is inserted into the pin hole of the hollow roller 130, and both ends of the pin 120 are connected to the small-diameter annular member 101 and the large-diameter annular member 110. . A screw hole 111 is drilled in the small-diameter annular member 101 and the large-diameter annular member 110 from the outer diameter side to the inner diameter side, and an eye bolt 140 is screwed into the screw hole 111. The roller bearing is suspended and conveyed by a crane using the eyebolt 140. A cage 100 including a small-diameter annular member 101 and a large-diameter annular member 110 and a pin 120 is configured.

前記ねじ穴１１１は、組み立て完了後にアイボルト１４０を螺合させて使用するものであって、組み立て前にアイボルト１４０を螺合させて使用するものではない。   The screw hole 111 is used by screwing the eyebolt 140 after the assembly is completed, and is not used by screwing the eyebolt 140 before the assembly.

ころ軸受の組み立ては、大径環状部材、中空ころ、小径環状部材の順に積み重ね、中空ころのピン穴にピンを挿入してピンの両端を小径環状部材および大径環状部材に連結することによってなされる。図８に示すように前記積み重ね方向に小径環状部材１６０を中空ころ１５０に対して降ろすには、小径環状部材１６０にピンの軸方向にねじ穴１６１を穿孔し、中空ころ１５０と反対側よりねじ穴１６１にアイボルト１７０のおねじ部１７２を螺合させる必要がある。   Roller bearings are assembled by sequentially stacking large-diameter annular members, hollow rollers, and small-diameter annular members, inserting pins into the pin holes of the hollow rollers, and connecting both ends of the pins to the small-diameter and large-diameter annular members. The As shown in FIG. 8, in order to lower the small-diameter annular member 160 to the hollow roller 150 in the stacking direction, a screw hole 161 is drilled in the small-diameter annular member 160 in the axial direction of the pin. The threaded portion 172 of the eyebolt 170 needs to be screwed into the hole 161.

特開平１１−１０１２４５号公報JP-A-11-101245

前記ねじ穴１６１にアイボルト１７０のおねじ部１７２を螺合させるときに、作業者は、アイボルト１７０を緩ませたくない気持ちがあるため、アイボルト１７０のフランジ部１７１が小径環状部材１６０に当接するまでアイボルト１７０をねじ込んでしまう。この結果、アイボルト１７０のおねじ部１７２の一端が小径環状部材１６０に対して中空ころ１５０側へはみ出し、中空ころ１５０の小径側端面に当たって傷付けてしまう問題があった。本発明は、上述した問題点を解決するためになされたもので、その目的とするところは、アイボルトによってころの端面を傷付けないころ軸受を提供する。   When the threaded portion 172 of the eyebolt 170 is screwed into the threaded hole 161, the operator does not want to loosen the eyebolt 170, so that the flange portion 171 of the eyebolt 170 abuts against the small-diameter annular member 160. The eyebolt 170 is screwed. As a result, there is a problem that one end of the threaded portion 172 of the eyebolt 170 protrudes toward the hollow roller 150 with respect to the small-diameter annular member 160 and hits the small-diameter side end surface of the hollow roller 150. The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a roller bearing that does not damage the end face of the roller with an eyebolt.

請求項１に記載の発明は、ピン穴を形成したころと、ピン穴に挿通されるピンを有し、このピンを介して前記ころを回転可能に支持した保持器とからなり、前記保持器は、軸方向に互いに離間して配置された第１環状部材および第２環状部材と、前記第１環状部材および前記第２環状部材を連結するとともに円周方向に間隔を空けて複数配置した前記ピンとからなり、前記第１環状部材にアイボルトを取付けるためのねじ穴を前記ピンと平行に貫通して形成したころ軸受において、前記ねじ穴の前記ピン側の端部にこの端部を潰すことによってねじ止めを形成したことを特徴とするものである。   The invention according to claim 1 comprises a roller having a pin hole and a retainer having a pin inserted through the pin hole and rotatably supporting the roller through the pin. The first annular member and the second annular member that are spaced apart from each other in the axial direction, and the first annular member and the second annular member are connected to each other, and a plurality of the annular members are arranged at intervals in the circumferential direction. In a roller bearing comprising a pin and having a screw hole for attaching an eyebolt to the first annular member formed in parallel with the pin, a screw is obtained by crushing the end of the screw hole at the end of the screw side. A stop is formed.

本発明によれば、ねじ穴にアイボルトを螺合させたときに、アイボルトの一端がねじ止めに当たるので、アイボルトが第１環状部材に対しころ側へ出っ張ることが無くなり、アイボルトによってころの端面を傷付けないころ軸受を提供することができる。   According to the present invention, when the eyebolt is screwed into the screw hole, one end of the eyebolt comes into contact with the screw, so that the eyebolt does not protrude to the roller side with respect to the first annular member, and the end surface of the roller is damaged by the eyebolt. No roller bearing can be provided.

It is composed of a ring-shaped cage 40 and a plurality of tapered rollers 30 that are rotatably supported by pins 60 (to be described later) of the cage 40. The outer ring 11, the inner ring 20, the retainer 40, and the tapered roller 30 are all made of a metal material, and particularly, an iron-based material is often used.

前記外輪１１の内周には、外輪１１の軸線に対して傾斜した外輪側軌道面１２が形成されている。   On the inner periphery of the outer ring 11, an outer ring side raceway surface 12 that is inclined with respect to the axis of the outer ring 11 is formed.

前記内輪２０の外周には、内輪２０の軸線に対して傾斜した内輪側軌道面２３が形成されている。また内輪２０の外周には、内輪側軌道面２３を挟んで大径側に半径方向外方へ突出した大径側端部２５が形成され、内輪側軌道面２３を挟んで小径側に半径方向外方へ突出した小径側端部２１が形成されている。   On the outer periphery of the inner ring 20, an inner ring-side raceway surface 23 that is inclined with respect to the axis of the inner ring 20 is formed. A large-diameter end 25 is formed on the outer periphery of the inner ring 20 so as to protrude radially outward on the large diameter side with the inner ring side raceway surface 23 interposed therebetween. A small-diameter end 21 projecting outward is formed.

大径側端部２５の円すいころ３０側の端面には、円すいころ３０の大径側端面に接触する大径側内側端面２４が形成されている。小径側端部２１の円すいころ３０側の端面には、円すいころ３０の小径側端面に接触する小径側内側端面２２が形成されている。   A large-diameter side inner end surface 24 that contacts the large-diameter side end surface of the tapered roller 30 is formed on the end surface of the large-diameter side end portion 25 on the tapered roller 30 side. A small-diameter side inner end surface 22 that contacts the small-diameter side end surface of the tapered roller 30 is formed on the end surface of the small-diameter side end portion 21 on the tapered roller 30 side.

前記保持器４０は、リング状で小径の小径環状部材５０と、リング状で大径の大径環状部材５５と、前記小径環状部材５０および前記大径環状部材５５を連結するピン６０とからなっている。   The cage 40 includes a ring-shaped small-diameter small-diameter member 50, a ring-shaped large-diameter large-diameter annular member 55, and a pin 60 that connects the small-diameter annular member 50 and the large-diameter annular member 55. ing.

前記小径環状部材５０には、ピン６０を挿通する挿通穴５１が貫通して形成されている。前記大径環状部材５５には、ピン６０を螺合する固定ねじ穴５６が貫通して形成されている。固定ねじ穴５６は、挿通穴５１に対応する位置に形成され、固定ねじ穴５６および挿通穴５１は円周方向に等間隔に複数形成されている。   The small diameter annular member 50 is formed with an insertion hole 51 through which the pin 60 is inserted. The large-diameter annular member 55 is formed with a fixing screw hole 56 through which the pin 60 is screwed. The fixing screw holes 56 are formed at positions corresponding to the insertion holes 51, and a plurality of the fixing screw holes 56 and the insertion holes 51 are formed at equal intervals in the circumferential direction.

また小径環状部材５０には、一対の挿通穴５７間で取付ねじ穴５３が形成されている（図６）。大径環状部材５５には、一対の固定ねじ穴５６間で取付ねじ穴５７が形成されている。取付ねじ穴５７は、取付ねじ穴５３に対応する位置に形成され、取付ねじ穴５３および取付ねじ穴５７は円周方向に等間隔に３乃至４箇所に形成されている。   The small-diameter annular member 50 has a mounting screw hole 53 formed between the pair of insertion holes 57 (FIG. 6). A mounting screw hole 57 is formed between the pair of fixing screw holes 56 in the large-diameter annular member 55. The attachment screw holes 57 are formed at positions corresponding to the attachment screw holes 53, and the attachment screw holes 53 and the attachment screw holes 57 are formed at three to four positions at equal intervals in the circumferential direction.

取付ねじ５３の円すいころ３０側に端部には、ねじ止め５４が形成されている。図３に示すように、取付ねじ５３は、予めねじ切り加工によって貫通して形成されている。一端にテーパ部９６を有するポンチ９５を取付ねじ５３の他端より挿入し、テーパ部９６で取付ねじ５１の一部を押し潰すことによって、ねじ止め５４が形成される。ねじ止め５４は、一山あるいは二山のねじを塑性変形させたものである。   A screwing 54 is formed at the end of the mounting screw 53 on the tapered roller 30 side. As shown in FIG. 3, the mounting screw 53 is formed in advance by threading. A punch 95 having a tapered portion 96 at one end is inserted from the other end of the mounting screw 53, and a part of the mounting screw 51 is crushed by the tapered portion 96, thereby forming a screw stop 54. The screwing 54 is obtained by plastically deforming one or two screws.

図５に示すように取付ねじ５３および取付ねじ５７には、アイボルト８０が螺合される。アイボルト８０は、輪部８１、フランジ部８２、おねじ部８３とからなる。輪部８１には、後述するロープ８８が挿通され、おねじ部８３は取付ねじ５３および取付ねじ５７に螺合される。   As shown in FIG. 5, an eyebolt 80 is screwed onto the mounting screw 53 and the mounting screw 57. The eyebolt 80 includes a ring portion 81, a flange portion 82, and a male screw portion 83. A rope 88 (described later) is inserted through the ring portion 81, and the male screw portion 83 is screwed into the attachment screw 53 and the attachment screw 57.

図１に示すように前記ピン６０には、一端に工具が回転方向に係合する係合溝６１が形成され、他端に固定ねじ穴５６に螺合するおねじ６３が形成されている。ピン６０には、係合溝６１からおねじ６３にかけてピン穴３１に摺接する嵌合部６１が形成されている。挿通穴５１およびピン６０間には、メカニカルロック７０が介挿され、このメカニカルロック７０によってピン６０は小径環状部材５０に固定される。ピン６０は内輪２０の円周方向に等間隔に複数設けられ、各ピン６０は円すいころ３０の後述するピン穴３１に挿通されている。これによって、各ピン６０に円すいころ３０が回転可能に支持されている。   As shown in FIG. 1, the pin 60 is formed with an engaging groove 61 that engages the tool in the rotational direction at one end and a male screw 63 that is screwed into the fixing screw hole 56 at the other end. The pin 60 is formed with a fitting portion 61 slidably contacting the pin hole 31 from the engaging groove 61 to the male screw 63. A mechanical lock 70 is inserted between the insertion hole 51 and the pin 60, and the pin 60 is fixed to the small-diameter annular member 50 by the mechanical lock 70. A plurality of pins 60 are provided at equal intervals in the circumferential direction of the inner ring 20, and each pin 60 is inserted into a pin hole 31 described later of the tapered roller 30. Thereby, the tapered roller 30 is rotatably supported by each pin 60.

前記円すいころ３０は、円すい形状から頂部を除去した形状を有するもので、前記外輪側軌道面１２と前記内輪側軌道面２３上を転動する転動面と、小径側の端面に形成された小径側端面と、大径側の端面に形成された大径側端面を有する。円すいころ３０には、ピン６０を挿通するピン穴３１が軸方向に形成されている。   The tapered roller 30 has a shape obtained by removing a top portion from a conical shape, and is formed on a rolling surface that rolls on the outer ring side raceway surface 12 and the inner ring side raceway surface 23, and an end surface on the small diameter side. It has a small diameter side end surface and a large diameter side end surface formed on the large diameter side end surface. The tapered roller 30 is formed with a pin hole 31 through which the pin 60 is inserted in the axial direction.

続いて上述した構成にもとづいて、円すいころ軸受１０の組付けについて説明する。   Next, the assembly of the tapered roller bearing 10 will be described based on the configuration described above.

固定部９０には、水平な第１載置面９１、水平な第２載置面９２、傾斜した第３載置面９３が形成されている。第１載置面９１、第２載置面９２、第３載置面９３の順に高くなっている。   The fixed portion 90 is formed with a horizontal first placement surface 91, a horizontal second placement surface 92, and an inclined third placement surface 93. The first placement surface 91, the second placement surface 92, and the third placement surface 93 are higher in this order.

第２載置面９２に大径環状部材５５を載置し、続いて第１載置面９１に内輪２０を載置し、第３載置面および大径側内側端面２４に円すいころ３０を載置し、円すいころ３０に小径環状部材５０を載置する。大径環状部材５５、内輪２０、小径環状部材５０を移送、載置するときは、アイボルト８０、ロープ８８およびクレーンを使用する。   The large-diameter annular member 55 is mounted on the second mounting surface 92, the inner ring 20 is subsequently mounted on the first mounting surface 91, and the tapered rollers 30 are mounted on the third mounting surface and the large-diameter side inner end surface 24. The small-diameter annular member 50 is placed on the tapered roller 30. When the large-diameter annular member 55, the inner ring 20, and the small-diameter annular member 50 are transferred and placed, an eye bolt 80, a rope 88, and a crane are used.

小径環状部材５０を移送、載置するときの例を説明する。   An example of transferring and placing the small-diameter annular member 50 will be described.

別の場所に載置された小径環状部材５０の取付ねじ穴５３に、アイボルト８０のおねじ部８３を螺合させる。おねじ部８３の一端がねじ止め５４に当たり、アイボルト８０のおねじ部８３のそれ以上の螺合を阻止し、アイボルト８０が小径環状部材５０から円すいころ３０側へはみ出すことが無くなる。   The male thread portion 83 of the eyebolt 80 is screwed into the mounting screw hole 53 of the small-diameter annular member 50 placed at another location. One end of the external thread 83 hits the screw stop 54 to prevent further screwing of the external thread 83 of the eyebolt 80, and the eyebolt 80 does not protrude from the small diameter annular member 50 to the tapered roller 30 side.

クレーンの吊り金具８５を、小径環状部材５０の水平方向の重力中心と思われるところへ移動させる。アイボルト８０にロープ８８を通し、このロープ８８を吊り金具８５のフック８７に掛ける。金属製ロープ８９は、下へ吊り下げられ、吊り金具８５のプーリ８６を経て、上へ吊り上げられている。上へ吊り上げられている部分の金属製ロープ８９をさらに上へ吊り上げると、吊り金具８５とともに小径環状部材５０が上昇する。   The crane's hanging bracket 85 is moved to a place where the small-diameter annular member 50 is considered to be the center of gravity in the horizontal direction. The rope 88 is passed through the eyebolt 80, and the rope 88 is hung on the hook 87 of the hanging bracket 85. The metal rope 89 is suspended downward, and is suspended upward via the pulley 86 of the suspension fitting 85. When the portion of the metal rope 89 that is lifted upward is lifted further upward, the small-diameter annular member 50 rises together with the suspension fitting 85.

小径環状部材５０を円すいころ３０上へ移送し、吊り金具８５とともに小径環状部材５０を下降させ、円すいころ３０上へ小径環状部材５０を載置する。このとき、アイボルト８０が小径環状部材５０から円すいころ３０側へはみ出していないため、アイボルト８０の一端で円すいころ３０の小径側端面を傷付けることが無くなる。   The small-diameter annular member 50 is transferred onto the tapered roller 30, the small-diameter annular member 50 is lowered together with the hanging metal fitting 85, and the small-diameter annular member 50 is placed on the tapered roller 30. At this time, since the eye bolt 80 does not protrude from the small diameter annular member 50 to the tapered roller 30 side, the end of the small diameter side of the tapered roller 30 is not damaged at one end of the eye bolt 80.

続いて上述した構成にもとづいて、円すいころ軸受１０の作用について説明する。   Next, the operation of the tapered roller bearing 10 will be described based on the configuration described above.

外輪１１に対して内輪２０が回転すると、円すいころ３０は外輪側軌道面１２上と内輪側軌道面２３上を転動しながら内輪２０の回転方向と同方向に移動する。円すいころ３０はピン６０によって回転可能に支持され、ピン６０同士を小径環状部材５０および前記大径環状部材５５を介して内輪２０の円周方向に連結しているため、複数の円すいころ３０は、一斉に内輪２０の回転方向と同方向に移動する。保持器４０も内輪２０と同方向に回転する。   When the inner ring 20 rotates with respect to the outer ring 11, the tapered rollers 30 move in the same direction as the rotation direction of the inner ring 20 while rolling on the outer ring side raceway surface 12 and the inner ring side raceway surface 23. The tapered rollers 30 are rotatably supported by pins 60, and the pins 60 are connected to each other in the circumferential direction of the inner ring 20 via the small-diameter annular member 50 and the large-diameter annular member 55. , And simultaneously move in the same direction as the rotation direction of the inner ring 20. The cage 40 also rotates in the same direction as the inner ring 20.

このとき、円すいころ３０の小径側端面に傷が無いため、円すいころ３０の小径側端面が小径環状部材５０に接触しても、円すいころ３０はスムーズに回転しながら内輪２０の回転方向へ移動する。   At this time, since the end surface on the small diameter side of the tapered roller 30 is not damaged, even if the end surface on the small diameter side of the tapered roller 30 contacts the small diameter annular member 50, the tapered roller 30 moves in the rotational direction of the inner ring 20 while smoothly rotating. To do.

内輪２０に軸方向のスラスト力が作用すると、円すいころ３０の大径側端面が大径側内側端面２４に接触し、さらに円すいころ３０を介して外輪１１に前記スラスト力が作用する。   When an axial thrust force acts on the inner ring 20, the large-diameter side end surface of the tapered roller 30 comes into contact with the large-diameter side inner end surface 24, and the thrust force acts on the outer ring 11 via the tapered roller 30.

本発明はこうした実施形態に何等限定されるものではなく、本発明の要旨を逸脱しない範囲において、種々なる態様で実施し得ることは勿論である。   The present invention is not limited to these embodiments, and can of course be implemented in various modes without departing from the gist of the present invention.
