Description

そして、第1の発明は、上記一方及び他方の掛け止め部は、上記コイルスプリングの内側あるいは外側に突出してなるとともに、上記第2回転体一対の部材からなり、一方の部材には上記一方の掛け止め部が接触する一方の接触面を形成し、他方の部材には上記他方の掛け止め部が接触する他方の接触面を形成、上記両回転体の一方の相対回転方向に対して一方の掛け止め部を一方の部材の接触面に接触させるかあるいは一定の間隔を保ち、他方の相対回転方向に対して他方の掛け止め部を他方の接触面に接触させるかあるいは一定の間隔を保つとともに上記一方及び他方の両接触面の軸方向長さを、上記コイルスプリングを形成する線材の太さより長くする構成にし、上記両掛け止め部と両接触面との相対位置を特定した組み付け状態を保って上記両部材を固定したものである。 The first invention, the one and the other latch portion, it becomes to protrude inside or outside of the coil spring, the second rotary member comprises a pair of members, the one on one of the members latch portion forms a contact surface of one of the contact, the other member to form the other contact surface retaining portion over the other contacts, to one of the relative rotational direction of the two rotary bodies One latching part is brought into contact with the contact surface of one member or kept at a constant interval, and the other latching part is brought into contact with the other contact surface with respect to the other relative rotation direction, or a constant interval is kept. together keep assembled the axial length of both contact surfaces of the one and the other, a configuration made longer than the thickness of the wire forming the coil spring, identified the relative position between the two retaining portions and the both contact surfaces Condition Keeping the is obtained by fixing the two members.

図14に示した第1実施形態は、筒状の第1回転体R1を、同じく筒状の第2回転体R2に相対回転可能に挿入している。
上記第1回転体R1は、図2からも明らかなように、その中心に軸孔1を形成するとともに、この軸孔1の一方の端面に環状凸部2を形成し、この環状凸部2にはその直径方向に一対の凹部3,3を形成している。
このようにした第1回転体R1の軸孔1には、図示していない回転軸を挿入するが、この回転軸には、その直径方向に一対のピンを起立させ、このピンを上記凹部3,3に挿入して、第1回転体R1と上記回転軸とが一体回転する構成にしている。
In the first embodiment shown in FIGS. 1 to 4, the cylindrical first rotating body R1 is inserted into the same cylindrical second rotating body R2 so as to be relatively rotatable.
As is apparent from FIG. 2, the first rotating body R <b> 1 has a shaft hole 1 at the center thereof, and an annular protrusion 2 formed on one end surface of the shaft hole 1. A pair of recesses 3 and 3 is formed in the diameter direction.
A rotation shaft (not shown) is inserted into the shaft hole 1 of the first rotating body R1 thus configured, and a pair of pins are erected on the rotation shaft in the diametrical direction, and the pins are inserted into the recess 3. , 3 so that the first rotating body R1 and the rotating shaft rotate together.

また、上記軸受部7に隣接する内側には、内径を軸受部7よりも大きくした肉厚部8を形成しているが、この肉厚部8の内径を、第1回転体R1の外周にはめたコイルスプリングSの外径よりもさらに大きくしている。そして、この肉厚部8には、図24からも明らかなように、掛け止め凹部9を形成し、その掛け止め凹部9内には、上記第1回転体R1にはめたコイルスプリングSの一方の掛け止め部5を挿入する。そして、この掛け止め凹部9内で、円周方向において対向する一方の側面を接触面9aとし、コイルスプリングSの掛け止め部5がこの接触面9aに接触するようにしている。 Further, a thick part 8 having an inner diameter larger than that of the bearing part 7 is formed on the inner side adjacent to the bearing part 7, and the inner diameter of the thick part 8 is formed on the outer periphery of the first rotating body R1. The outer diameter of the fitted coil spring S is further increased. As shown in FIGS. 2 to 4, a latching recess 9 is formed in the thick portion 8, and a coil spring S fitted to the first rotating body R <b> 1 is formed in the latching recess 9. One of the latching portions 5 is inserted. In the latch recess 9, one side surface facing in the circumferential direction is a contact surface 9 a, and the latch portion 5 of the coil spring S is in contact with the contact surface 9 a.

Claims (1)

第1回転体と第2回転体とを相対回転可能にするとともに、第1回転体にコイルスプリングの内径部あるいは外径部を圧接させる一方、コイルスプリングの一端に突出させた一方の掛け止め部と、他端に突出させた他方の掛け止め部のそれぞれを、第2回転体に掛け止めてなるトルクリミッタにおいて、上記一方及び他方の掛け止め部は、上記コイルスプリングの内側あるいは外側に突出してなるとともに、上記第2回転体は一対の部材からなり、一方の部材には上記一方の掛け止め部が接触する一方の接触面を形成し、他方の部材には上記他方の掛け止め部が接触する他方の接触面を形成し、上記両回転体の一方の相対回転方向に対して一方の掛け止め部を一方の部材の接触面に接触させるかあるいは一定の間隔を保ち、他方の相対回転方向に対して他方の掛け止め部を他方の接触面に接触させるかあるいは一定の間隔を保つとともに上記一方及び他方の両接触面の軸方向長さを、上記コイルスプリングを形成する線材の太さより長くする構成にし、上記両掛け止め部と両接触面との相対位置を特定した組み付け状態を保って上記両部材を固定したトルクリミッタ。 The first rotating body and the second rotating body can be rotated relative to each other, and the inner diameter portion or the outer diameter portion of the coil spring is brought into pressure contact with the first rotating body, while one latching portion protruded from one end of the coil spring.
