Title (EN) GEAR GRINDING MACHINE
(FR) MACHINE DE MEULAGE D'ENGRENAGE
(JA) 歯車研削盤
Abstract:
(EN) Provided is a gear grinding machine for grinding a gear by causing a gear that is to be ground and a grindstone to rotate in a meshed state, wherein the gear grinding machine makes it possible to suppress the generation of waviness during the grinding. This gear grinding machine is characterized by being provided with a grindstone (21) for grinding a gear, a grindstone shaft (22) for supporting the grindstone (21), bearings for supporting the grindstone shaft (22) so as to enable rotation about the axis thereof, a preloading mechanism (40) for applying a preload to the bearings, and a control unit configured so as to control the preload applied by the preloading mechanism (40) in accordance with the rotational speed of the grindstone shaft (22).
(FR) L'invention concerne une machine de meulage d'engrenage permettant de meuler un engrenage en amenant un engrenage devant être meulé et une meule à tourner dans un état engrené, la machine de meulage d'engrenage permettant de supprimer la génération d'ondulations pendant le meulage. La machine de meulage d'engrenage selon l'invention est caractérisée en ce qu'elle est dotée d'une meule (21) permettant de meuler un engrenage, d'un arbre de meule (22) permettant de supporter la meule (21), de paliers permettant de supporter l'arbre de meule (22) de manière à permettre une rotation autour de son axe, d'un mécanisme de précharge (40) permettant d'appliquer une précharge aux paliers et d'une unité de commande configurée de manière à commander la précharge appliquée par le mécanisme de précharge (40) en fonction de la vitesse de rotation de l'arbre de meule (22).
(JA) 研削加工の対象とされる歯車と砥石を噛合わせた状態で互いに回転させることにより、歯車を研削加工する歯車研削盤であって、研削加工する際にうねりの発生を抑制できる歯車研削盤を提供する。本発明の歯車研削盤は、歯車を研削加工する砥石(21)と、砥石(21)を支持する砥石軸(22)と、砥石軸(22)をその軸線周りに回転可能に支持する軸受と、軸受に予圧を与える予圧付与機構(40)と、砥石軸(22)の回転数に応じて、予圧付与機構(40)による予圧を制御するように構成される制御部と、を備えることを特徴とする。
