Abstract

PURPOSE:To eliminate a backlash so as to enable a gear wheel to be rotated precisely and smoothly by providing a slitting on an addendum of a gear wheel in parallel with a tooth trace. CONSTITUTION:A slitting 1b is formed approximately in the center of an addendum 1a of a gear tooth 1 of a spur gear in parallel with a tooth trace. By doing so, the gear tooth 1 divided into sections by the slitting 1b deforms elastically and absorbs a pitch error, a tooth profile error, etc. Therefore, the gear wheel can be rotated more precisely and smoothly than the former gear wheel without giving any hindrance to the rotating movement even if it is constituted to eliminate backlashes completely.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は歯車、特に、その歯先面の改良に関する。[Detailed description of the invention] [Industrial application field] TECHNICAL FIELD The present invention relates to gears, and in particular to improvements to the tooth tips thereof.

〔従来の技術〕[Conventional technology]

歯車は、一対の歯車を噛み合せたとき、ピッチ円に沿っ
て一定の隙間、所謂バックラッシが生じるよう構成され
ている。Gears are configured so that when a pair of gears are meshed, a certain gap, or so-called backlash, occurs along a pitch circle.

トが高くなる等の問題点があった。Among these, for example, a double gear is one in which two gears are attached to one shaft via a spring so that they can rotate by a small angle, and one gear transmits power while the other gear transmits power. Although this has the effect of eliminating backlash, it requires twice the width of the gold teeth of the gear, resulting in higher costs and other problems.

また、バックラッシを無くすか、又は極めて小さくする
と、歯車の回転が円滑に行なわれなくなる等、種々の問
題が生じてしまい、未だこれらの問題を解決するには至
っていない。Furthermore, if backlash is eliminated or extremely reduced, various problems arise, such as the gear not rotating smoothly, and these problems have not yet been solved.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

本発明は紙上の観点に立ってなされたものであって、そ
の目的とするところは、歯車のバックラッシを無くし、
精密で且つ円滑な回転を実現し得る歯車を提供すること
にある。The present invention was made from a paper perspective, and its purpose is to eliminate backlash of gears,
The purpose of the present invention is to provide a gear that can realize precise and smooth rotation.

ｃ問題点を解決するための手段〕 而して、上記の目的は、歯車の歯先面に、歯スジに平行
なすり割りを設けると共に、バックラッシが無くなるよ
う歯厚及び軸間距離を定めることによって達成される。Measures to Solve Problem c] Therefore, the above purpose is to provide slots parallel to the tooth line on the tooth tip surface of the gear, and to determine the tooth thickness and the distance between the shafts so that backlash will be eliminated. achieved by.

〔作　　用〕[For production]

上記の如く構成することにより、すり割りより分断され

になる。With the above configuration, the teeth separated by the slots can be elastically deformed and absorb pitch errors, tooth profile errors, etc., so even if the configuration is designed to completely eliminate bank crush, There are no obstacles and it can be rotated more precisely and smoothly than conventional gears.

〔実　施　例〕〔Example〕

以下、図面により本発明の詳細を具体的に説明する。 Hereinafter, the details of the present invention will be specifically explained with reference to the drawings.

第１図乃至第４図は、それぞれ本発明かかる無背隙歯車
の一実施例を示す説明図であり、その歯先面の構成を示
す説明図である。FIGS. 1 to 4 are explanatory views showing one embodiment of the backless gear according to the present invention, and are explanatory views showing the structure of the tooth tip surface thereof.

第１図乃至第４図中、１は平歯車の歯、１ａはその歯先
面であり、ｌｂ乃至１ｅはそれぞれ上記歯先面ｌに形成
されたすり割りである。In FIGS. 1 to 4, 1 is a tooth of a spur gear, 1a is its tooth tip surface, and lb to 1e are slots formed on the tooth tip surface l, respectively.

第１図に示したものは、平歯車の歯ｌの歯先面ｌａの略
中央部に、歯スジに平行にすり割り１ｂを形成したもの
である。In the gear shown in FIG. 1, a slot 1b is formed approximately in the center of the tip surface la of the tooth l of a spur gear in parallel to the tooth line.

上記すり割り１ｂは通常放電加工装置等によって形成さ
れるが、フライス又はメタルソー等によっても形成され
る。The slot 1b is usually formed using an electrical discharge machining device, but may also be formed using a milling cutter, a metal saw, or the like.

而して、本発明にかかる無背隙歯車は、一対の歯車が噛
み合った際に、歯車間にバックラッシが全（生じないも
のである。Thus, in the backless gear according to the present invention, no backlash occurs between the gears when the pair of gears mesh with each other.

而して、一方の歯車が他方の歯車に押圧されて回転を開
始するとき、いずれか一方の歯車のピッチ誤差等があり

断された歯１のばね作用により歯面圧力が吸収されるの
で、上記歯面圧力が異常に増大することがなく、従って
歯車の回転が阻止されたり、抵抗が異常に増加したりす
ることがないものである。Therefore, when one gear is pressed by the other gear and starts rotating, if there is a pitch error in one of the gears and interference occurs, the teeth separated by the slot lb. Since the tooth surface pressure is absorbed by the spring action of 1, the tooth surface pressure will not increase abnormally, and therefore the rotation of the gear will not be blocked or the resistance will not increase abnormally. .

而して、左右両方向に回転せしめられ、左右両方向から
同一の負荷が加わる場合には、歯先面１ａに形成するす
り割りは、第１図乃至第３図に示す如（歯形の中心線に
沿って対称になるよう形成することが推奨される。Therefore, when the tooth is rotated in both the left and right directions and the same load is applied from both the left and right directions, the slot formed on the tooth tip surface 1a is as shown in FIGS. It is recommended that it be formed symmetrically along the

また、一方方向にのみ回転し、歯車に一方向にのみ重負
荷が加わった状態で回転する歯車に於ては、第４図に示
す如く、すり割りｌｅを歯形の中心線に対して非対称に
なるよう形成することが推奨される。In addition, for gears that rotate only in one direction and with a heavy load applied to the gear in only one direction, the slots le should be made asymmetrically with respect to the center line of the tooth profile, as shown in Figure 4. It is recommended that it be formed as follows.
