接力器耳柄锁紧结构

Servomotor ear handle locking structure

Abstract

本实用新型涉及一种接力器耳柄锁紧结构,活塞杆外螺纹配装在耳柄内螺纹中,耳柄内螺纹沿轴向过中心轴线切有3mm通槽,耳柄内螺纹与活塞杆外螺纹面紧密接触配合。本实用新型利用小型螺栓的径向预紧替代传统的大型非标螺母轴向预紧,操作方便,提高了联接的可靠性,降低了制造成本。
The utility model relates to a servomotor ear handle locking structure, which is characterized in that external thread of a piston rod is assembled into internal thread of an ear handle, a 3mm through groove is cut on the internal thread of the ear handle along the axial direction and passing through the central axis, and the internal thread of the ear handle is in close surface contacting fit with the external thread of the piston rod. The servomotor ear handle locking structure utilizes radial pretightening of small bolts to replace the conventional axial pretightening of large nonstandard nuts, is convenient in operation, increases reliability of connection and reduces manufacturing cost.
