| description | The present invention relates to a sintered bearing and a linear actuator, and the present invention suppresses deviation of an oscillation frequency of a movable element or a generation of a joint when the linear actuator is operated. According to the present invention, the linear actuator (1) comprises: a fixing shaft (20); and the movable element (30) moved along the fixing shaft (20). The movable element (30) comprises: a main body unit (31) having a permanent magnet; and the bearing (32) arranged on each end in an axial direction of the main body unit (31). An insertion through hole (h2) which the fixing shaft (20) is inserted into and passes through is formed in each bearing (32). The inner diameter of the bearing unit (x), wherein a bearing surface (b) is formed, is formed within a range of 0.4-0.8 mm in each bearing (32). Moreover, a chamfer unit (y) continuously formed to the bearing unit (x) is formed on at least one among both ends in an axial direction of the insertion through hole (h2).
[과제] 리니어 액츄에이터의 구동시에 있어서의 이음의 발생이나 가동자의 진동수의 편차를 억제한다. [해결 수단] 본 발명에 의한 리니어 액츄에이터(1)는 고정축(20)과, 고정축(20)을 따라 이동되는 가동자(30)를 구비하고 있다. 가동자(30)는 영구 자석을 가지고 이루어지는 본체부(31)와, 본체부(31)의 축방향의 각 단부에 배치된 베어링(32)을 갖고 있다. 각 베어링(32)에는 고정축(20)이 삽입통과되는 삽입통과 구멍(h2)이 형성되어 있다. 그리고, 각 베어링(32)에서는 베어링면(b)이 형성되어 있는 베어링부(x)의 내경이 0.4㎜ 이상 0.8㎜ 이하의 범위 내로 형성되고, 또한 삽입통과 구멍(h2)의 축방향의 양 단부 중 적어도 한쪽에 베어링부(x)에 연속되는 모따기부(y)가 형성되어 있다. |
