一般に自在継手は例えば特開昭５６−４６１２０号公報
にあるようなたわみ軸継手方式等が知られている。In general, a flexible joint system such as that disclosed in Japanese Patent Application Laid-Open No. 56-46120 is known as a universal joint.

ない限り満足する製品が得にくい、一方駆動軸から被駆
動軸への回転トルクはボールの摺動面を通して行われて
いるので角度精度が出しにくく、伝達精度が劣る。The flexible shaft coupling method transmits rotational force by interposing a movable pin between the drive shaft and the driven shaft. Both ends of each drive pin are supported through balls, and the balls are attached to the end surface of the sleeve. It has a structure in which it is held between annular bodies. Therefore, there are many component parts, and it is difficult to obtain a satisfactory product unless the dimensional accuracy of each part is improved.On the other hand, since the rotational torque from the driving shaft to the driven shaft is performed through the sliding surface of the ball, it is difficult to achieve angular accuracy. , transmission accuracy is poor.
更に駆動ピンがボールの摺動であるため駆動軸と被駆動
軸の軸方向の移動を規制しない限り両者は離脱し１組立
も雛しい。Furthermore, since the driving pin is a sliding ball, unless the axial movement of the driving shaft and driven shaft is restricted, the two will separate and it will be difficult to assemble them.
又、出願人は特願昭６０−４４８２９号において類似構

分に配慮されていなかった。Furthermore, the applicant proposed a universal joint with a similar structure in Japanese Patent Application No. 60-44829, but sufficient consideration was not given to transmission efficiency.

の軸方向の移動を規制しない限り両者は離脱し、組立も
難しい。The above-mentioned conventional technology has poor transmission accuracy, and unless the axial movement of the drive shaft and the driven shaft is restricted, the two come apart and are difficult to assemble.
本発明の目的は、構造簡単にしてトルク伝達が確実な自
在継手を提供するにある。An object of the present invention is to provide a universal joint with a simple structure and reliable torque transmission.

タガイドピンで支持することにより達成される。The above purpose is to slidably support the shaft portions of a pair of drive pins, one end of which is rotatably fixed at a position symmetrical to the axis of the end face of the drive shaft, on the driven shaft, and insert the shaft portion into the drive pin insertion hole. When the drive pin is tilted and rotational torque is applied, the circumferential side surface of the drive pin tip is prevented from moving in the circumferential direction by the wall of the insertion hole, and the drive shaft and driven shaft are This is achieved by supporting each shaft center with a center guide pin fixed to the driven shaft using a fixed pin.

When a rotational torque is applied, the circumferential side surface of the tip of the drive pin is prevented from moving in the circumferential direction by the wall of the insertion hole, and torque is transmitted.

。Further, an edge receiving surface is formed on the axis of the end surface of the drive shaft, and the spherical head of the center guide pin is rotatably connected and fixed to the edge receiving surface after being fitted. The center guide pin provided on the drive shaft and the center guide pin insertion hole of the driven shaft opposing it make the drive shaft and driven shaft concentric, resulting in high dimensional accuracy between the related components and greatly improved 1-luke transmission accuracy. improves.

の着脱が容易となっている。Like the drive shaft 1, the driven shaft 2 is processed and formed by cold forging or cutting, and has a center guide pin insertion hole 11 into which the shaft portion 9a of the center guide pin 9 is inserted in the longitudinal direction on the axis. A pair of drive pin insertion holes 7 into which the shaft portion 3a of the drive pin 3 is inserted are provided axially symmetrically. This center guide pin insertion hole 11 maintains a concentric relationship between the drive shaft 1 and the driven shaft 2, and the shaft portion 9a of the center guide pin
It is set to be about the same as the outer diameter or 1/100 (1m) 8 degrees wider. The drive pin insertion hole 7 is provided through the end face in order to accommodate the one-spherical bearing 5, but is open in the radial direction at the rear. As can be seen from FIG. 2, if the distance from the center of the drive pin 3 to the inner wall surface 7a is a, the distance is narrower than the distance #iL from the center of the drive pin 3 to the bottom surface.1 There is n between the two. The relationship <L is established. This Ω width is 2/100 from the outer diameter of the shaft portion 3a of the drive pin.
(am) wide setting so that rotational torque is effectively transmitted. In addition, the center guide pin 9, which is located on the axis of the end surface of the drive shaft 1, passes through the fixed pin 10 from the side surface of the shaft and is fixed to the driven shaft 2, so that the drive shaft 1 and the driven shaft 2 are in a concentric relationship. Therefore, the transmission of rotational torque becomes even more effective. This fixing pin 10 is inserted into a fixing pin insertion hole that passes through the driven shaft 2 in the diametrical direction, and is prevented from coming out by a ring 8 that fits into a groove provided in the circumferential direction on the outer periphery of the driven shaft 2. There is. From this, the fixing pin 10 can be removed, and the driving shaft 1 and the driven shaft 2
It is easy to put on and take off.

The joint is fixed by locally plastically deforming the parts. Note that the driving shaft 1 and the driven shaft 2 are made of aluminum or the like.

る。Next, if we talk about the torque transmission mechanism of this joint, one end of the drive pin 3 is rotatably fixed to the drive shaft 1, and the other end is slidably and movably held on the driven shaft 2. In the series state as shown in FIG. 1, when the WA drive shaft rotates, the drive pin 3 also rotates concentrically with it, transmitting rotational torque to the driven shaft 2 side. That is, when the tip of the shaft portion 3a of the drive pin 3 moves in the circumferential direction using the ball-centered bearing 5 as a fulcrum and comes into contact with the inner wall surface 7a of the drive pin insertion hole 7, the drive pin is deflected and rotational torque is transmitted. In this case, the drive II'
A center guide pin 9 provided on the axis of the end face of 1l11 and a center guide pin insertion hole 1 of the driven shaft 2 facing it
1, the driving shaft 1 and the driven shaft 2 are concentric, resulting in high dimensional accuracy between related components and greatly improving torque transmission accuracy.
一方第５図の如く二つの駆動軸間に傾斜角を持たせた場
合も基本的動作は第１図と同様であるが、各駆動ピンは
最小角から最大角に移動する際駆動ピン挿入穴７を摺動
し、一回転で一往復する。On the other hand, when the two drive shafts have an inclination angle as shown in Fig. 5, the basic operation is the same as in Fig. 1, but each drive pin is inserted into the drive pin insertion hole when moving from the minimum angle to the maximum angle. 7 and makes one reciprocation in one rotation.
駆動ピン３とセンタガイドピン９は頭部４を有し、それ
を駆動軸に固設する構造であるため、他方の軸部の組付
に集中するだけでよく離脱の心配がなくて組付やすく生
産性が一段と向上する構成である。The drive pin 3 and the center guide pin 9 have a head 4, which is fixed to the drive shaft, so you only need to concentrate on assembling the other shaft part, and there is no need to worry about it coming off. It is a configuration that is easy to use and improves productivity even further.
更に、駆動ピン３の軸部先端が挿入穴の内壁面に微少移
動することで回転トルクの伝達が被駆動軸２にあるので
上記構成に加えて精度の高いトルク伝達が行われる。Furthermore, since the tip of the shaft portion of the drive pin 3 moves slightly toward the inner wall surface of the insertion hole, rotational torque is transmitted to the driven shaft 2, so that in addition to the above configuration, highly accurate torque transmission is performed.
尚実施例では駆動軸および被駆動軸の端面に線受面を形
成し、そこにそれぞれ駆動ピンの頭部と球心軸受を嵌合
し金属素材の塑性変形を利用して固設しているが同等の
結合、精度が得られるならば特に限定されない。In this embodiment, wire bearing surfaces are formed on the end surfaces of the driving shaft and the driven shaft, and the head of the driving pin and the spherical bearing are respectively fitted thereon and fixed using plastic deformation of the metal material. There is no particular limitation as long as equivalent combination and accuracy can be obtained.
もちろん、駆動軸、被駆動軸は便宜上定義して説明しで
あるが駆動軸側を反対にしても継手機能を満足すること
は言うまでもない。Of course, the driving shaft and driven shaft are defined and explained for convenience, but it goes without saying that the joint function can be satisfied even if the driving shaft sides are reversed.
又、先願技術に比較してもセンタガイドピンによって常
に同軸が確保され、駆動ピンが２本であるため機械的ロ
スが少なく伝達効率が一段と向上する。Also, compared to the prior art, coaxiality is always ensured by the center guide pin, and since there are two drive pins, mechanical loss is reduced and transmission efficiency is further improved.
以上本発明によれば、構造簡単にしてトルク伝達が確実
