Title (EN) DUAL-TYPE WAVE GEAR DEVICE
(FR) DISPOSITIF D'ENGRENAGE À ONDE DE TYPE DOUBLE
(JA) デュアルタイプの波動歯車装置
Abstract:
(EN) A dual-type wave gear device (1) wherein an external gear (4) is equipped with first and second external teeth (7, 8) which are different in tooth number, and gaps (9) formed therebetween and serving as a cutter clearance portion for a teeth-cutting cutter. When the maximum width of the gaps (9) is L1, the depth from the tooth crest surface of the first external tooth (7) to the deepest part (9a) of the gap (9) is t1, the tooth height of the first external tooth (7) is h1, the depth from the tooth crest surface of the second external tooth (8) to the deepest part (9a) is t2, and the tooth height of the second external tooth (8) is h2, any of the conditions 1–3 are satisfied. Condition 1: L1 = 0.1L – 0.35L, t1 = 0.9h1 – 1.3h1, t2 = 0.3h2 – 0.9h2 Condition 2: L1 = 0.1L – 0.35L, t1 = 0.3h1 – 0.9h1, t2 = 0.9h2 – 1.3h2 Condition 3: L1 = 0.1L – 0.35L, t1 = 0.3h1 – 0.9h1, t2 = 0.3h2 – 0.9h2 Thus, it is possible to implement a dual-type wave gear device for which the tooth bottom fatigue strength and the wear resistance of the external gear can be increased.
(FR) La présente invention concerne un dispositif d'engrenage à ondes de type double (1), un engrenage externe (4) étant équipé de premières et secondes dents externes (7, 8) qui sont différentes en nombre et des espaces (9) étant formés entre elles et servant de partie de dégagement de dispositif de coupe pour un dispositif de coupe à dents. Lorsque la largeur maximale des espaces (9) est L1, la profondeur de la surface de crête de la première dent externe (7) à la partie la plus profonde (9a) de l'espace (9) est t1, la hauteur de la première dent externe (7) est h1, la profondeur de la surface de crête de la seconde dent externe (8) à la partie la plus profonde (9a) est t2 et la hauteur de la seconde dent externe (8) est h2, l'une quelconque des conditions 1 à 3 est satisfaite. Condition 1 : L1 = 0,1L – 0,35L, t1 = 0,9h1 – 1,3h1, t2 = 0,3h2 – 0,9h2 Condition 2 : L1 = 0,1L – 0,35L, t1 = 0,3h1 – 0,9h1, t2 = 0,9h2 – 1,3h2 Condition 3 : L1 = 0,1L – 0,35L, t1 = 0,3h1 – 0,9h1, t2 = 0,3h2 – 0,9h2 Ainsi, il est possible de mettre en œuvre un dispositif d'engrenage à ondes de type double dont on peut augmenter la résistance à la fatigue de fond de dent et la résistance à l'usure de l'engrenage externe.
(JA) デュアルタイプの波動歯車装置(1)の外歯歯車(4)は、歯数が異なる第1、第2外歯(7、8)と、これらの間に形成した、歯切り用カッターのカッター逃げ部としての隙間(9)とを備える。隙間(9)の最大幅をL1、第1外歯(7)の歯先面から隙間(9)の最深部(9a)までの深さをt1、第1外歯(7)の歯丈をh1、第2外歯(8)の歯先面から最深部(9a)までの深さをt2、第2外歯(8)の歯丈をh2とすると、次の条件1~3のうちのいずれかを満たす。 条件1:L1=0.1L-0.35L, t1=0.9h1-1.3h1, t2=0.3h2-0.9h2 条件2:L1=0.1L-0.35L, t1=0.3h1-0.9h1, t2=0.9h2-1.3h2 条件3:L1=0.1L-0.35L, t1=0.3h1-0.9h1, t2=0.3h2-0.9h2 外歯歯車の耐摩耗性および歯底疲労強度を高めたデュアルタイプの波動歯車装置を実現できる。
