【発明の詳細な説明】
（イ）産業上の利用分野
この発明は、シャフトの回転を伝導するためのジヨイン
トゴムに関するものである。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a joint rubber for transmitting rotation of a shaft.
（ロ）従来の技術
従来のジヨイントゴムは大別して２つの方法に帰着する
。(b) Prior Art Conventional joint rubbers can be roughly divided into two methods.
１つは、ジヨイントゴムにシャフトを嵌挿するだけの圧
着方式である。幾つかの具体例を挙げるならば、ジヨイ
ントゴムの口径よりも大きなシーヤフトを嵌挿する方法
、シャフトを嵌挿したその上からカシメでもって固定す
る方法、もしくはどスとナツトで係止してしまう方法が
ある。シャフトの着脱に若干の困難を有するが、なによ
り廉価であるかととシャフトの回転軸とジヨイントゴム
の中心線を容易に合致させることができるという大きな
長所がある。One is a crimping method in which the shaft is simply inserted into the joint rubber. To give some specific examples, a method of inserting a sea shaft larger than the diameter of the joint rubber, a method of inserting a shaft and fixing it by caulking from above, or a method of locking with a bolt and a nut. There is. Although there is some difficulty in attaching and detaching the shaft, the major advantages are that it is inexpensive and that the axis of rotation of the shaft and the center line of the joint rubber can be easily aligned.
もう１つは、ジヨイントゴムの内部全体が雌螺子を切り
た金屑の貫入によって形成されたインサート方式であり
、シャフト側の連結部分は雄螺子に形成されている。ジ
ヨイントとシャフトの堅固な固定か可能であり、その上
着脱が容易でしかも短時間の内に作業を完了すことか出
来るという特徴がある。The other type is an insert type in which the entire interior of the joint rubber is formed by inserting metal scraps into a female thread, and the connecting portion on the shaft side is formed into a male thread. It is possible to firmly fix the joint and shaft, and it is easy to attach and detach the top, and the work can be completed in a short time.
、八）発明が解決しようとする問題点
上述したような従来の２つの方法には夫々以下の問題点
がある。, 8) Problems to be Solved by the Invention The two conventional methods described above each have the following problems.
圧着方式のジヨイントゴムにおいてはシャフトの若脱が
容易でない点とジヨイントゴムとシャフトの間に緩みが
生じる可能性のある点であり、インサート方式のジヨイ
ントゴムにおいては金属雌螺子の貫入の際に生じる隙間
等によって回転軸と中心線とを合致させることが困難て
あるため、回転に伴う振動か激しくて騒音を生じてしま
い、又、シャフト及びジヨイントの耐用期間が短いと云
う点が挙げられる。With crimp-type joint rubber, it is difficult to remove the shaft prematurely, and there is a possibility that loosening may occur between the joint rubber and the shaft.In insert-type joint rubber, rotation is caused by the gap created when the female metal screw penetrates. Since it is difficult to align the axis with the center line, vibrations caused by rotation are strong and generate noise, and the service life of the shaft and joint is short.
この発明は、上記双方の問題点を同時に解決するジヨイ
ントゴムを提供することを目的とすこの発明は、シャフ
トを連結するジヨイントにおいて、その連結部をゴム圧
着部と金属雌螺子部とによって構成したことを特徴とす
るジヨイントゴムである。The object of the present invention is to provide a joint rubber that simultaneously solves both of the above-mentioned problems.The present invention provides a joint for connecting shafts, in which the connecting portion is composed of a rubber crimping portion and a metal female screw portion. This joint rubber is characterized by:
（ネ）作用
上記のように構成されたジヨイントゴムにおいては金属
雌螺子部によってシャフトを堅固に嵌合するのでシャフ
トとジヨイントゴムの間で緩みの生ずる恐れはないし、
しかも螺子式なのてシャフトの着脱が容易である。又、
ジヨイントゴムに嵌挿したシャフトの大部分の外周側面
はゴム穴部の内周側面に密着するように挿入されている
ので、シャフトの回転軸とジヨイントゴムの中心線とが
合致してスムーズな回転か得られるため振動に伴う騒音
も生じない。よってシャフト及びジヨイントゴムか破損
することは少なく耐用時間の長いものとなる。(f) Function In the joint rubber constructed as described above, the shaft is firmly fitted by the female metal thread, so there is no risk of loosening between the shaft and the joint rubber.
Moreover, since it is a screw type, it is easy to attach and detach the shaft. or,
Most of the outer peripheral side of the shaft inserted into the joint rubber is inserted so that it is in close contact with the inner peripheral side of the rubber hole, so the axis of rotation of the shaft matches the center line of the joint rubber, resulting in smooth rotation. Therefore, no noise is generated due to vibration. Therefore, the shaft and joint rubber are less likely to be damaged and have a long service life.
以上の理由から、シャフトが挿入される長さ、即ちジヨ
イントゴムのゴム穴部の長さを金属雌螺子部に比して長
くとることでこの発明はより有効に作用する。For the above reasons, the present invention works more effectively by making the length into which the shaft is inserted, that is, the length of the rubber hole of the joint rubber, longer than that of the female metal thread.
