Electric cylinder and electric cylinder system

摘要

An electric cylinder includes: an outer cylinder including, on one end side, a fixing section; a rod configured to be capable of expanding and contracting in an axis direction from an opening on the one end side of the outer cylinder; a bearing provided on the other end side end and on the inside of the outer cylinder; a rotating shaft supported by the bearing and driven to rotate; a screw mechanism configured to convert a rotational motion of the rotating shaft into a linear motion of the rod and transmit the linear motion; and a distortion detecting unit provided on the outer circumference of the outer cylinder. The outer cylinder includes at least two or more division members that can be divided and combined. The distortion detecting unit is provided in one division member among the two or more division members.

1. An electric cylinder comprising:
an outer cylinder including, on a first end side, a fixing section for fixing the electric cylinder to an attachment place; a rod configured to be capable of projection as expanding in an axis direction from an opening on the first end side of the outer cylinder and configured to be capable of retraction as contracting in the axis direction to the inside from the opening; a bearing provided on a second end side and on an inside of the outer cylinder; a rotating shaft rotatably supported by the bearing and driven to rotate by a driving force of a motor; a screw mechanism configured to convert a rotational motion of the rotating shaft into a linear motion of the rod and transmit the linear motion; and a distortion detecting unit provided in a position between a position on an outer circumference of the outer cylinder where the bearing is provided and the fixing section, wherein the outer cylinder includes at least two or more division members that can be divided and combined, and the distortion detecting unit is provided in one division member among the two or more division members.
