用于提供线性驱动并具有自锁功能。
专利摘要
一种致动器,优选为线性致动器,一种可逆电机,其通过传动装置驱动调节元件。为了增加致动器的自锁能力,致动器配备有螺旋弹簧,螺旋弹簧的一端固定在致动器中的旋转元件上,使得弹簧在圆柱部分上随旋转一起被带动,该圆柱部分相对于旋转元件是静止的。当电机关闭,并且致动器上的负载试图移动调节元件时,螺旋弹簧的运动被阻止,并且螺旋弹簧被收紧在圆柱部分上。
Original abstractAn actuator, preferably a linear actuator, a reversible motor which drives an adjustment element via a transmission. To increase the self-clocking ability of the actuator, the actuator is equipped with a coil spring which has its one end secured to a rotating element in the actuator so that the spring is carried along in the rotation on the cylindrical part, which is static in relation thereto. When the motor is turned off, and the load on the actuator tries to displace the adjustment element, the movement of the coil spring is blocked, and the coil spring is tightened around the cylindrical part.
