Description

本発明のある側面に係るプーリ装置は、固定シーブと、筒状の固定ボスと、可動シーブと、筒状の可動ボスと、軸受部材と、シール部材と、を備える。固定ボスは、固定シーブから軸方向に延びる。可動シーブは、軸方向において固定シーブに対して接近及び離間するように移動可能である。可動ボスは、可動シーブから軸方向に延びる。また、可動ボスは、径方向において固定ボスの外側に配置される。軸受部材は、固定ボス内に取り付けられる。シール部材は、軸受部材の外径よりも大きい外径を有する。また、シール部材は、固定ボス内に取り付けられる。また、シール部材は、軸方向において軸受部材の外側に配置される。固定ボスは、第1取付部、第2取付部、及び抜け止め部を有する。第1取付部は、軸受部材が取り付けられる。第2取付部は、第1取付部の内径よりも大きい内径を有する。また、第2取付部は、シール部材が取り付けられる。抜け止め部は、軸方向において第2取付部の外側に配置される。抜け止め部は、軸受部材の外径よりも大きく且つシール部材の外径より小さい内径を有する。
The pulley device according to a certain side surface of the present invention includes a fixed sheave, a cylindrical fixed boss, a movable sheave, a tubular movable boss, a bearing member, and a seal member. The fixed boss extends axially from the fixed sheave. The movable sheave is movable in the axial direction so as to approach and separate from the fixed sheave. The movable boss extends axially from the movable sheave. Further, the movable boss is arranged outside the fixed boss in the radial direction. The bearing member is mounted within the fixed boss. The seal member has an outer diameter larger than the outer diameter of the bearing member. Further, the seal member is mounted in the fixed boss. Further, the seal member is arranged outside the bearing member in the axial direction. The fixed boss has a first mounting portion, a second mounting portion, and a retaining portion. A bearing member is attached to the first attachment portion. The second mounting portion has an inner diameter larger than the inner diameter of the first mounting portion. A seal member is attached to the second attachment portion. The retaining portion is arranged outside the second mounting portion in the axial direction. The retaining portion has an inner diameter larger than the outer diameter of the bearing member and smaller than the outer diameter of the sealing member.

好ましくは、シール部材は、内部に金属環を有する。この構成により、さらにシール部材が固定ボス内から抜け落ちにくくなる。
好ましくは、軸受部材は、第1取付部に圧入される。
Preferably, the sealing member has a metal ring inside. With this configuration, the seal member is more difficult to come off from the fixed boss.
Preferably, the bearing member is press-fitted into the first mounting portion.

固定ボス3は、例えば、金属製であり、好ましくは鋼製又はアルミニウム合金製である。また、固定ボス3の本体部及び固定シーブ1をアルミニウム合金によって一体的に形成し、固定ボス3の第1側端部31を鋼によって形成することができる。
The fixed boss 3 is made of, for example, metal, preferably steel or an aluminum alloy. Further, the main body portion of the fixed boss 3 and the fixed sheave 1 can be integrally formed of aluminum alloy, and the first side end portion 31 of the fixed boss 3 can be formed of steel.

アウターレース51は、金属製である。具体的には、アウターレース51は、冷間圧延鋼板(SPC材)製である。ニードル52は、金属製である。具体的には、ニードル52は、高炭素合鋼製、または中炭素合鋼製である。より具体的には、ニードル52は、高炭素クロム軸受鋼製である。また、保持器53は、金属製である。具体的には、保持器53は、低炭素の冷間又は熱間圧延鋼板製であり、オーステナイト系ステンレス鋼板を用いてもよい。
The outer race 51 is made of metal. Specifically, the outer race 51 is made of a cold-rolled steel plate (SPC material). The needle 52 is made of metal. Specifically, the needle 52 is made of high carbon steel or medium carbon steel. More specifically, the needle 52 is made of high carbon chrome bearing steel. Further, the cage 53 is made of metal. Specifically, the cage 53 is made of a low carbon cold or hot rolled steel plate, and an austenitic stainless steel plate may be used.

各クラッチシュー72の摩擦材がクラッチハウジング73の内周面と摩擦係合することによって、遠心クラッチ7は伝達状態となる。また、各クラッチシュー72の摩擦材がクラッチハウジング73の内周面から離れることによって、遠心クラッチ7は遮断状態になる。 When the friction material of each clutch shoe 72 is frictionally engaged with the inner peripheral surface of the clutch housing 73, the centrifugal clutch 7 is in a transmission state. Further, when the friction material of each clutch shoe 72 is separated from the inner peripheral surface of the clutch housing 73 , the centrifugal clutch 7 is in a disengaged state.
