Title (EN) GEAR, GEAR TRANSMISSION MECHANISM, AND METHOD FOR MANUFACTURING GEAR

Abstract:
(EN) In a gear (64) comprising a resin material including a fibrous filler, a plurality of teeth (641a) formed at equal angular intervals are provided to a first outer peripheral part (643). When the gear (64) is manufactured, the resin material is filled from a specific portion (645) (first toothless part (646)) which faces in a direction orthogonal to a center axis line (L64), and in which the teeth (641a) are not formed in a portion that overlaps the first outer peripheral part (643) when seen from the direction orthogonal to the center axis line (L64). Therefore, there is a gate mark (649) in the specific portion (645). Between the specific portion (645) and the center axis line (L64), the degree to which the filler is oriented in a direction intersecting the center axis line (L64) is higher than the degree to which the filler is oriented in a direction running along the center axis line (L64).
(FR) Dans un engrenage (64) comprenant un matériau de résine comprenant un matériau de remplissage fibreux, une pluralité de dents (641a) formées à des intervalles angulaires égaux sont prévues sur une première partie périphérique externe (643). Lorsque l'engrenage (64) est fabriqué, le matériau en résine est rempli à partir d'une partie spécifique (645) (première partie sans dent (646)) qui est tournée dans une direction orthogonale à une ligne d'axe central (L64), et dans laquelle les dents (641a) ne sont pas formées dans une partie qui chevauche la première partie périphérique externe (643) lorsqu'on regarde depuis la direction orthogonale vers la ligne d'axe central (L64). Par conséquent, un repère de porte (649) est présent dans la partie spécifique (645). Entre la partie spécifique (645) et la ligne d'axe central (L64), le degré selon lequel le matériau de remplissage est orienté dans une direction coupant la ligne d'axe central (L64) est supérieur au degré selon lequel le matériau de remplissage est orienté dans une direction s'étendant le long de la ligne d'axe central (L64).
(JA) 歯車(64)は、繊維状の充填材を含む樹脂材料からなり、等角度間隔に形成された複数の歯(641a)を第1外周部(643)に備えている。歯車(64)を製造する際、中心軸線(L64)に対して直交する方向からみたときに第1外周部(643)と重なる部分で歯(641a)が形成されずに中心軸線(L64)に対して直交する方向に向いた特定部分(645)(第1欠歯部(646))から樹脂材料が充填される。このため、特定部分(645)にゲート痕(649)が存在する。また、充填材は、特定部分(645)と中心軸線(L64)との間では、中心軸線(L64)に交差する方向に配向している度合が中心軸線(L64)に沿う方向に配向している度合より高い。
