| description | The invention provides a rotary joint (10) capable of shortening a radial length while ensuring rigidity. First circumferential grooves (first compressed air supply grooves (34), first pressure oil supply grooves (36), and a first coolant supply groove (38)) formed in a first sliding surface (28), and second circumferential grooves (second compressed air supply grooves (48), second pressure oil supply grooves (50), and a second coolant supply groove (52)) formed in a second sliding surface (30) are formed in the rotary joint (10) to be opposite to each other when seen from a radial direction of the rotary joint (10). In this case, in one pair of the opposite first circumferential groove and second circumferential groove, a type and a use of a fluid flowing in the first circumferential groove are the same as a type and a use of a fluid flowing in the second circumferential groove.
本发明提供种能够在确保刚性的同时缩短径向上的长度的旋转接头(10)。在旋转接头(10)中，形成于第滑动接触面(28)的第圆周槽(第压缩空气供给槽(34)、第压力油供给槽(36)、第冷却剂供给槽(38))和形成于第二滑动接触面(30)的第二圆周槽(第二压缩空气供给 |
