注射装置
摘要：
提供一种能够以简单的结构供给润滑剂的注射装置。上述注射装置包括：旋转滑动部件(40)，形成为筒状，在一侧连接有螺杆(31)，并且在另一侧连接有与注射马达(43)连接的滚珠丝杠(46)，在外周设置有第1花键(49)；和计量马达(42)，被配置为围绕旋转滑动部件(40)，通过计量马达(42)上所配置的第2花键(47)与第1花键(49)进行花键配合，使旋转滑动部件(40)旋转，旋转滑动部件(40)具有从该旋转滑动部件(40)的内侧向第1及第2花键(49、47)的配合位置供给润滑剂(61)的贯通孔(60)。
摘要（英）：

An injection device capable of supplying lubricant via a simple structure is provided. The injection device includes a rotary slide member (40) formed into a cylindrical shape and provided with a first spline (49) on an outer periphery thereof, one side of which is connected with a screw (31) and the other side of which is connected with a ball screw (46) connected with an injection motor (43); and a plasticizing motor (42) provided to surround the rotary slide member (40), having a second spline (47) adapted to engage with the first spline (49) and to rotate the rotary slide member. The rotary slide member (40) includes at least one supply passage (60) to supply lubricant from an inside of the rotary slide member (40) to an engagement location of the first spline and the second spline (49, 47).
