互に噛み合う１組の歯車には、熱変形や避けがたい工作
誤差があっても１円滑な動力伝達を行うようにするため
、一般に歯面に遊びが設けられである。[Detailed Description of the Invention] A set of gears that mesh with each other generally has play on the tooth surfaces in order to ensure smooth power transmission even if there is thermal deformation or unavoidable machining errors. be.
このために、歯車の負荷が変動する場合、駆動力が脈動
する場合、駆動速度が変化する場合、又は誤差のある歯
車を両速で回転させる場合などには、歯車の角速度が変
化し１．接触している噛み合い歯面が一時分離し１次に
たたき合うがたつき現象を生し、これが歯車の振ｆｆｌ
ＩＩＭ皆の大きな原因となっている。For this reason, when the load on the gear fluctuates, when the driving force pulsates, when the driving speed changes, or when a gear with an error is rotated at both speeds, the angular velocity of the gear changes.1. The meshing tooth surfaces that are in contact temporarily separate and cause a rattling phenomenon in which they strike each other in the first order, and this causes gear vibrationffl.
It is a big cause for everyone at IIM.
又、制御系に使用する歯車では、駆動歯車を停止させて
も、歯面の遊びの分だけ被動歯車がふらつき、制御性能
を低下させる原因となっている。Furthermore, in gears used in control systems, even when the driving gear is stopped, the driven gear wanders by the amount of play on the tooth surface, causing a reduction in control performance.
これらの欠点を軸滅するために、従来は、歯車ならびに
その周辺要素の精度を高め、極力歯面の遊びを少なくす
ることが実施されているが、経済性を犠牲にするだけで
なく、’ｍ１ｒｊの所びを零にすることはできないので
、その効果にも限界があった。In order to eliminate these drawbacks, conventional efforts have been made to improve the precision of gears and their surrounding elements and to reduce play between tooth surfaces as much as possible, but this not only sacrifices economic efficiency, but also Since it was not possible to reduce the length to zero, there was a limit to its effectiveness.
本発明は、歯面に遊びを有する歯車に対して。The present invention relates to gears that have play on tooth surfaces.
歯車と等しい回転比を有し、遊びのない摩擦車を固着す
ることにより、各種の原因により歯面が分離する作用を
ｉ［１，ｌ止し、歯車のがたつきゃふらつきを防止しよ
うとするものである。By fixing a friction wheel that has the same rotation ratio as the gear and has no play, it prevents the tooth surfaces from separating due to various causes, and prevents the gear from rattling and wobbling. It is something.
この発明の原理を図に基いて説明すると、第１図に示す

歯車１と歯車２の理想運動は、３と４で示すピッチ円筒
が濁りなしに接触して回転する運動であり。The ideal motion of gears 1 and 2 is a motion in which the pitch cylinders 3 and 4 rotate in contact with each other without turbidity.
３と４とが歯車１と歯車２との噛み合いピッチ円筒であ
る。3 and 4 are meshing pitch cylinders between gear 1 and gear 2.
歯車１の歯面は点５において歯車２の歯面に接触してお

触面８には圧力Ｐを加えて摩擦力を発生させる。このよ
うに構成しておけば、各種の原因によって歯車ががたつ
き、又はふらつこうとしても、接触面８に生じている摩
擦力によって、これを抑止することができる。The tooth surface of the gear 1 is in contact with the tooth surface of the gear 2 at a point 5, and a tooth surface C is provided on the opposite tooth surface. When the angular velocity of the gear changes, the gear rattles or wobbles by this amount of play C. Friction wheels 6 and 7 having the same rotation ratio as the gear are respectively fixed to this gear, and a pressure P is applied to the contact surface 8 of the friction wheels to generate a friction force. With this configuration, even if the gear rattles or wobbles due to various causes, this can be suppressed by the frictional force generated on the contact surface 8.
