(EN) CONSTANT VELOCITY UNIVERSAL JOINT
(FR) JOINT HOMOCINETIQUE
(JA) 等速自在継手
要約
(EN)
A constant velocity universal joint having compactness and achieving sufficient strength, durability, load capacity, and operation angle. Six balls (3) are arranged in the constant velocity universal joint. The ratio r1 (= PCDBALL/DBALL) between the pitch circle diameter PCDBALL (PCDBALL = 2 × PCR) of the balls (3) and the diameter DBALL of a ball (3) is set in the range of 1.5 ≤ r1 ≤ 4.0, and the ratio r2 (= DOUTER/PCDSERR) between the outer diameter DOUTER of an outer member (1) and the pitch circle diameter PCDSERR of serrations (or splines)(2d) of an inside coupling member (2) is set in the range of 3.0 ≤ r2 ≤ 5.0.
(FR)
Joint homocinétique ayant une certaine compacité et possédant une résistance, une durabilité, une capacité de charge et un angle de fonctionnement suffisants. Six billes (3) sont disposées dans le joint homocinétique. Le rapport r1 (= PCDBILLE/DBILLE) entre le diamètre du cercle primitif PCDBILLE (PCDBILLE = 2 × PCR) des billes (3) et le diamètre DBILLE d'une bille (3) est fixé dans la plage de 1,5 ≤ r1 ≤ 4,0, et le rapport r2 (= DEXTERNE/PCDSERR) entre le diamètre extérieur DEXTERNE d'un organe externe (1) et le diamètre du cercle primitif PCDSERR des of serrations (ou cannelures)(2d) d'un organe d'accouplement interne (2) est fixé dans la plage de 3,0 ≤ r2 ≤ 5,0.
(JA)
本願発明は、等速自在継手のコンパクト化、強度、耐久性、負荷容量、作動角の確保を目的とする。等速自在継手にはボール3が6個配置されている。ボール3のピッチ円径PCDBALL(PCDBALL=2×PCR)と直径DBALLとの比r1(=PCDBALL/DBALL)は、1.5≦r1≦4.0の範囲、外方部材1の外径DOUTERと内側継手部材2のセレーション(又はスプライン)2dのピッチ円径PCDSERRとの比r2(=DOUTER/PCDSERR)は、3.0≦r2≦5.0の範囲内の値に設定されている。
