特開２０００−３４６１７４号公報JP 2000-346174 A

内筒の中途部に径方向外側に突出した部分が設けてあるので、内筒の形状は複雑である。内筒の外周を研磨加工する場合、内筒の製造時間が長くなり、製造費用も嵩む。   Since a portion protruding radially outward is provided in the middle part of the inner cylinder, the shape of the inner cylinder is complicated. When polishing the outer periphery of the inner cylinder, the manufacturing time of the inner cylinder becomes longer and the manufacturing cost increases.

本発明は斯かる事情に鑑みてなされたものであり、容易に製造可能なカムフォロワ及び該カムフォロワを備える伝動機構を提供することを目的とする。   This invention is made | formed in view of such a situation, and it aims at providing the transmission mechanism provided with the cam follower which can be manufactured easily, and this cam follower.

本発明に係るカムフォロワは、対象物の一面に形成した凹部に一端側を挿入してあり、前記凹部から他端側が突出した内筒と、該内筒の他端部にて径方向外側に設けてあり、転動体を介して軸回りに回転する外筒と、前記凹部の底面に穿設した雌螺子と、前記内筒に挿入してあり、前記雌螺子に螺合して、前記内筒を前記対象物に固定する雄螺子とを備えるカムフォロワにおいて、前記内筒の一端部は前記凹部の底面に当接しており、前記内筒の他端部に前記外筒の端面に対向する鍔を設けてあり、前記雄螺子の軸方向にて、前記外筒及び凹部の寸法の和は、前記鍔から前記内筒の一端部までの前記内筒の寸法よりも小さいことを特徴とする。   The cam follower according to the present invention has one end inserted into a recess formed on one surface of an object, and is provided on the radially outer side at the other end of the inner cylinder protruding from the recess and the other end. An outer cylinder that rotates about an axis via a rolling element, a female screw that is drilled in the bottom surface of the recess, and an inner cylinder that is inserted into the inner cylinder, and is screwed into the female thread. In the cam follower including a male screw that fixes the object to the object, one end portion of the inner cylinder is in contact with the bottom surface of the recess, and a flange facing the end surface of the outer cylinder is formed on the other end portion of the inner cylinder. The sum of the dimensions of the outer cylinder and the recess in the axial direction of the male screw is smaller than the dimension of the inner cylinder from the flange to one end of the inner cylinder.

本発明に係るカムフォロワは、前記内筒の前記一端部の角部分にテーパ又は曲面を周方向に設けてあることを特徴とする。   The cam follower according to the present invention is characterized in that a taper or a curved surface is provided in a circumferential direction at a corner portion of the one end portion of the inner cylinder.

本発明に係るカムフォロワは、前記内筒の前記他端部の角部分にテーパ又は曲面を周方向に設けてあることを特徴とする。   The cam follower according to the present invention is characterized in that a taper or a curved surface is provided in a circumferential direction at a corner portion of the other end portion of the inner cylinder.

本発明に係る伝動機構は、上述したいずれかのカムフォロワと、該カムフォロワが係合するカム溝を有するカムとを備えることを特徴とする。   A transmission mechanism according to the present invention includes any one of the cam followers described above and a cam having a cam groove with which the cam follower is engaged.

本発明においては、内筒の一端部が凹部の底面に当接しているので、内筒の中途部に突出部分を設ける必要がなく、内筒の構成は簡素になる。また雄螺子の軸方向における外筒及び凹部の寸法の和を、対応する内筒の寸法よりも小さく設定し、外筒及び転動体と対象物の一面の間に隙間を形成する。   In the present invention, since the one end portion of the inner cylinder is in contact with the bottom surface of the recess, it is not necessary to provide a protruding portion in the middle of the inner cylinder, and the configuration of the inner cylinder is simplified. Further, the sum of the dimensions of the outer cylinder and the recess in the axial direction of the male screw is set to be smaller than the dimensions of the corresponding inner cylinder, and a gap is formed between the outer cylinder and the rolling element and one surface of the object.

本発明においては、内筒の一端部の角部分外周がテーパ状又は曲面状をなす。切削加工で凹部を形成した場合、凹部の隅部分に削り残しがある場合がある。一端部の角部分はテーパ状又は曲面状をなすので、削り残しに干渉しない。一端部は凹部に確実に嵌まり、凹部における一端部の位置ずれを防止することができる。   In the present invention, the outer periphery of the corner portion at one end of the inner cylinder is tapered or curved. When the concave portion is formed by cutting, there may be an uncut portion at the corner portion of the concave portion. Since the corner portion at one end is tapered or curved, it does not interfere with uncut material. One end part fits into a recessed part reliably, and the position shift of the one end part in a recessed part can be prevented.

本発明においては、内筒の他端部の角部分外周がテーパ状又は曲面状をなす。切削加工でカム溝を形成した場合、カム溝の隅部分に削り残しがある場合がある。他端部の角部分はテーパ状又は曲面状をなすので、カム溝に嵌まった場合、削り残しに干渉しない。他端部はカム溝に円滑に嵌まり、カムからカムフォロワへの力の伝達が円滑になる。   In the present invention, the outer periphery of the corner portion at the other end of the inner cylinder is tapered or curved. When cam grooves are formed by cutting, there may be uncut portions at the corners of the cam grooves. Since the corner of the other end is tapered or curved, it does not interfere with uncut material when it is fitted in the cam groove. The other end fits smoothly into the cam groove, and the force is smoothly transmitted from the cam to the cam follower.

本発明に係るカムフォロワ及び伝動機構にあっては、内筒の一端部が凹部の底面に当接しているので、内筒の中途部に突出部分を設ける必要がなく、内筒の構成は簡素になり、製造費用及び製造時間は短縮する。内筒の製造時間及び製造費用を削減することができる。また雄螺子の軸方向における外筒及び凹部の寸法の和を、対応する内筒の寸法よりも小さく設定し、外筒及び転動体と対象物の一面の間に隙間を形成して、外筒の円滑な回転を実現する。   In the cam follower and the transmission mechanism according to the present invention, since one end of the inner cylinder is in contact with the bottom surface of the recess, it is not necessary to provide a protruding portion in the middle of the inner cylinder, and the configuration of the inner cylinder is simplified. Thus, the manufacturing cost and the manufacturing time are shortened. The manufacturing time and manufacturing cost of the inner cylinder can be reduced. Further, the sum of the dimensions of the outer cylinder and the recess in the axial direction of the male screw is set to be smaller than the dimension of the corresponding inner cylinder, and a gap is formed between one surface of the outer cylinder and the rolling element, and the outer cylinder. To achieve smooth rotation.

以下本発明を実施の形態に係る伝動機構を示す図面に基づいて説明する。図１は伝動機構を略示する部分断面図、図２は図１の部分拡大断面図である。   Hereinafter, the present invention will be described with reference to the drawings illustrating a transmission mechanism according to an embodiment. FIG. 1 is a partial sectional view schematically showing a transmission mechanism, and FIG. 2 is a partially enlarged sectional view of FIG.

伝動機構は例えばローラギヤカムであり、ローラギヤカムは入力軸１及び出力軸３（対象物）を備える。入力軸１及び出力軸３は直交する。出力軸３と直交する部分において、入力軸１にカム２が設けてある。カム２は、入力軸１の外周面に形成した螺旋状のカム溝２ａを備える。出力軸３の外周面には、複数のカムフォロワ４が周方向に並設してある。   The transmission mechanism is, for example, a roller gear cam, and the roller gear cam includes an input shaft 1 and an output shaft 3 (object). The input shaft 1 and the output shaft 3 are orthogonal. A cam 2 is provided on the input shaft 1 at a portion orthogonal to the output shaft 3. The cam 2 includes a spiral cam groove 2 a formed on the outer peripheral surface of the input shaft 1. A plurality of cam followers 4 are arranged in the circumferential direction on the outer peripheral surface of the output shaft 3.

出力軸３の外周面には、各カムフォロワ４に対応する凹部３ａが設けてある。凹部３ａの底面３ｂには雌螺子３ｃが穿設してある。カムフォロワ４は内筒５、外筒７、転動体９及び雄螺子８を備える。内筒５の一端側は凹部３ａに挿入してある。内筒５は雌螺子３ｃに対して同軸的に配置してある。内筒５の一端部の角部分には、外側に突出した曲面５ａが全周に亘って設けてある。なお曲面５ａに代えてテーパを設けてもよい。内筒５の一端部の端面は凹部３ａの底面３ｂに当接している。   On the outer peripheral surface of the output shaft 3, a recess 3a corresponding to each cam follower 4 is provided. A female screw 3c is formed in the bottom surface 3b of the recess 3a. The cam follower 4 includes an inner cylinder 5, an outer cylinder 7, rolling elements 9, and male screws 8. One end side of the inner cylinder 5 is inserted into the recess 3a. The inner cylinder 5 is disposed coaxially with the female screw 3c. A curved surface 5a protruding outward is provided at the corner of one end of the inner cylinder 5 over the entire circumference. A taper may be provided instead of the curved surface 5a. The end surface of the one end part of the inner cylinder 5 is in contact with the bottom surface 3b of the recess 3a.

内筒５の他端部には、径方向外向きに突出した鍔６が設けてある。凹部３ａの反対側において、鍔６の角部分にテーパ６ａが全周に亘って設けてある。なおテーパ６ａに代えて曲面を設けてもよい。内筒５の他端部の端面には座繰り５ｂが設けてある。   The other end of the inner cylinder 5 is provided with a flange 6 protruding outward in the radial direction. On the opposite side of the recess 3a, a taper 6a is provided at the corner of the flange 6 over the entire circumference. A curved surface may be provided instead of the taper 6a. A counterbore 5b is provided on the end surface of the other end of the inner cylinder 5.

出力軸３に対向する鍔６の面は段状をなし、外側に位置する第一面６１と内側に位置する第二面６２を有する。出力軸３の外周面において、第一面６１及び第二面６２に対向する部分は平坦に形成してある（以下、出力軸３の外周面における平坦に形成した部分を平坦面３ｄという）。第一面６１と平坦面３ｄの間の寸法は第二面６２と平坦面３ｄの間の寸法よりも大きい。   The surface of the flange 6 facing the output shaft 3 is stepped and has a first surface 61 located on the outside and a second surface 62 located on the inside. In the outer peripheral surface of the output shaft 3, portions facing the first surface 61 and the second surface 62 are formed flat (hereinafter, a flat portion in the outer peripheral surface of the output shaft 3 is referred to as a flat surface 3d). The dimension between the first surface 61 and the flat surface 3d is larger than the dimension between the second surface 62 and the flat surface 3d.

外筒７は、内筒５の外側に同軸的に設けてある。外筒７は、内筒５の他端側において、平坦面３ｄと第一面６１の間に位置する。外筒７の一端面は第一面６１に対向し、他端面は平坦面３ｄに対向する。鍔６は外筒７を軸回りに回転可能に保持する。複数の転動体９を内筒５と外筒７の間に周方向に並設してある。転動体９は、内筒５及び外筒７に平行な円柱状をなし、第二面６２と平坦面３ｄの間に位置する。転動体９の一端面は第二面６２に対向し、他端面は平坦面３ｄに対向する。外筒７は転動体９を介して内筒５の周囲を回転する。   The outer cylinder 7 is provided coaxially outside the inner cylinder 5. The outer cylinder 7 is located between the flat surface 3 d and the first surface 61 on the other end side of the inner cylinder 5. One end surface of the outer cylinder 7 faces the first surface 61 and the other end surface faces the flat surface 3d. The flange 6 holds the outer cylinder 7 so as to be rotatable about its axis. A plurality of rolling elements 9 are juxtaposed between the inner cylinder 5 and the outer cylinder 7 in the circumferential direction. The rolling element 9 has a cylindrical shape parallel to the inner cylinder 5 and the outer cylinder 7 and is positioned between the second surface 62 and the flat surface 3d. One end surface of the rolling element 9 faces the second surface 62, and the other end surface faces the flat surface 3d. The outer cylinder 7 rotates around the inner cylinder 5 via the rolling elements 9.

雄螺子８は内筒５に挿入してある。雄螺子８は頭部８ａと軸部８ｂを備える。軸部８ｂは雌螺子３ｃに螺合する。頭部８ａは座繰り５ｂ内に位置し、内筒５から突出しない。頭部８ａは座繰り５ｂの底部に係止し、内筒５の一端部は底面３ｂに当接する。雄螺子８は内筒５を出力軸３に固定し、内筒５は外筒７を回転可能に保持する。   The male screw 8 is inserted into the inner cylinder 5. The male screw 8 includes a head portion 8a and a shaft portion 8b. The shaft portion 8b is screwed into the female screw 3c. The head 8 a is located in the counterbore 5 b and does not protrude from the inner cylinder 5. The head 8a is locked to the bottom of the counterbore 5b, and one end of the inner cylinder 5 is in contact with the bottom 3b. The male screw 8 fixes the inner cylinder 5 to the output shaft 3, and the inner cylinder 5 holds the outer cylinder 7 rotatably.

図２に示す如く、外筒７の軸方向寸法をＡとし、軸方向における凹部３ａの寸法（深さ）をＢとし、第一面６１から内筒５の一端部の端面（凹部３ａの底面３ｂ）までの内筒５の軸方向寸法をＣとした場合、カムフォロワ４はＡ＋Ｂ＜Ｃとなるように設計してある。   As shown in FIG. 2, the axial dimension of the outer cylinder 7 is A, the dimension (depth) of the recess 3 a in the axial direction is B, and the end surface of the inner cylinder 5 from the first surface 61 (the bottom surface of the recess 3 a). When the axial dimension of the inner cylinder 5 up to 3b) is C, the cam follower 4 is designed to satisfy A + B <C.

そのため外筒７と出力軸３の間及び転動体９と出力軸３の間に隙間が発生する。隙間によって、外筒７及び転動体９は回転することができる。換言すれば、外筒７の軸方向寸法は第一面６１と平坦面３ｄの間の寸法よりも小さく設計し、転動体９の軸方向寸法は第二面６２と平坦面３ｄの間の寸法よりも小さく設計する。   Therefore, gaps are generated between the outer cylinder 7 and the output shaft 3 and between the rolling elements 9 and the output shaft 3. The outer cylinder 7 and the rolling element 9 can be rotated by the gap. In other words, the axial dimension of the outer cylinder 7 is designed to be smaller than the dimension between the first surface 61 and the flat surface 3d, and the axial dimension of the rolling element 9 is the dimension between the second surface 62 and the flat surface 3d. Design smaller than.

実施の形態に係る伝動装置にあっては、内筒５の一端部の端面が凹部３ａの底面３ｂに当接しているので、内筒５の中途部に突出部分を設ける必要がなく、内筒５の構成は簡素になり、製造費用及び製造時間は短縮する。また雄螺子８の軸方向における外筒７及び凹部３ａの寸法の和（Ａ＋Ｂ）を、対応する内筒５の寸法（Ｃ）よりも小さく設定し、外筒７及び転動体９と平坦面３ｄとの間に隙間を形成して、外筒７の円滑な回転を実現する。   In the transmission device according to the embodiment, since the end surface of one end of the inner cylinder 5 is in contact with the bottom surface 3b of the recess 3a, there is no need to provide a protruding portion in the middle part of the inner cylinder 5, and the inner cylinder The configuration of 5 is simplified, and the manufacturing cost and the manufacturing time are shortened. Further, the sum (A + B) of the dimensions of the outer cylinder 7 and the recess 3a in the axial direction of the male screw 8 is set to be smaller than the dimension (C) of the corresponding inner cylinder 5, and the outer cylinder 7, the rolling element 9 and the flat surface 3d. A gap is formed between the outer cylinder 7 and the outer cylinder 7 to rotate smoothly.

また内筒５の一端部の角部分に曲面５ａを設けてある。切削加工で凹部３ａを形成した場合、凹部３ａの隅部分に削り残しがある場合がある。一端部の角部分に曲面５ａを設けてあるので、内筒５は削り残しに干渉しない。内筒５の一端部は凹部３ａに確実に嵌まり、凹部３ａにおける前記一端部の位置ずれを防止することができる。なお内筒５の一端部の角部分にテーパを設けた場合も同様である。   Further, a curved surface 5 a is provided at a corner portion at one end of the inner cylinder 5. When the recess 3a is formed by cutting, there is a case where there is an uncut portion at the corner of the recess 3a. Since the curved surface 5a is provided in the corner | angular part of one end part, the inner cylinder 5 does not interfere with uncut material. One end of the inner cylinder 5 is securely fitted in the recess 3a, and the position shift of the one end in the recess 3a can be prevented. The same applies to the case where a taper is provided at the corner of one end of the inner cylinder 5.

また鍔６（内筒５の他端部）の角部分にテーパ６ａを設けてある。切削加工でカム溝２ａを形成した場合、カム溝２ａの隅部分に削り残しがある場合がある。他端部の角部分にテーパ６ａを設けてあるので、カム溝２ａに嵌まった場合、内筒５は削り残しに干渉しない。内筒５の他端部はカム溝２ａに円滑に嵌まり、カム２からカムフォロワ４への力の伝達が円滑になる。なお内筒５の他端部の角部分に曲面を設けた場合も同様である。   Further, a taper 6a is provided at a corner portion of the flange 6 (the other end portion of the inner cylinder 5). When the cam groove 2a is formed by cutting, there is a case where there is an uncut portion in the corner portion of the cam groove 2a. Since the taper 6a is provided at the corner portion of the other end, the inner cylinder 5 does not interfere with the uncut portion when fitted in the cam groove 2a. The other end portion of the inner cylinder 5 fits smoothly into the cam groove 2a, and the transmission of force from the cam 2 to the cam follower 4 becomes smooth. The same applies when a curved surface is provided at the corner of the other end of the inner cylinder 5.

また実施の形態に係る伝動機構は、内筒５に雄螺子８を挿入して螺子止めするだけでカムフォロワ４を出力軸３に固定することができるので、出力軸３に貫通孔を設け、雄螺子８が貫通孔に挿入して、ナットに螺合する場合に比べて、取り付けが容易になる。   In the transmission mechanism according to the embodiment, the cam follower 4 can be fixed to the output shaft 3 simply by inserting the male screw 8 into the inner cylinder 5 and fastening the screw. As compared with the case where the screw 8 is inserted into the through hole and screwed into the nut, the attachment becomes easier.

また内筒５を中実ピンに変更し、中実ピンの周面に凹部を形成し、中実ピンに直交する方向に貫通した貫通孔を出力軸３に設け、貫通孔に雄螺子８を挿入して、中実ピンの凹部に雄螺子８が嵌合して中実ピンを出力軸３に固定する場合に比べて、実施の形態に係る伝動機構は、内筒５の径方向において雄螺子８が内筒５を押さないので、内筒５の位置がずれない。また内筒５の外周面に凹部を形成しないので、内筒５の強度が低下しない。   Further, the inner cylinder 5 is changed to a solid pin, a recess is formed in the peripheral surface of the solid pin, a through hole penetrating in a direction perpendicular to the solid pin is provided in the output shaft 3, and a male screw 8 is provided in the through hole. Compared to the case where the male screw 8 is inserted into the recess of the solid pin and the solid pin is fixed to the output shaft 3, the transmission mechanism according to the embodiment is male in the radial direction of the inner cylinder 5. Since the screw 8 does not push the inner cylinder 5, the position of the inner cylinder 5 does not shift. Moreover, since a recessed part is not formed in the outer peripheral surface of the inner cylinder 5, the intensity | strength of the inner cylinder 5 does not fall.
