    Abstract: A method for calibrating a powered actuator for use in a vehicle is provided, with regard to an end position of an actuating element which is easy to achieve and conserves easily damaged mechanical components of the actuator made from plastic, rubber or similar. According to an example embodiement, in a calibrating step, the actuator is operated with recording and analysis of an actuation speed measured parameter such that the actuating element is moved in the direction of the end position and reaching the end position is recognized when the value of the actuation speed measured parameter reaches or drops below a given threshold. A temperature parameter characterizing the temperature of the actuator is evaluated before or during the calibration process. The calibration step is then only carried out if the value of the temperature parameter does not exceed an upper temperature limit. An actuator suitable for carrying out said method is also disclosed.

    Abstract: Garage door opener for simple installation and to fully actuate various counterbalanced doors of different makes with minimum mechanism, and to be packaged and sold as a compact kit. The opener is built around a short main drive shaft adapted to be coupled coaxially to the end of the door counterbalance shaft. The drive shaft is journalled in two frame side members and therebetween carries a worm gear and two friction drive disks spring-pressed against the gear to transmit limited drive torque therefrom to the shaft. The gear is driven by a worm on the shaft of a motor on a carrier which is slidable on the frame. A manual cam moves the carrier between a worm-engaged position for drive and a worm-disengaged position to release the door for manual operation. A threaded extension of the main shaft carries a pair of traveling nuts which actuate switches to limit door travel both directions. In one modification, the assembly is mounted on studs on a mounting plate and adjusted thereto to bring the drive shaft coaxial with the counterbalance shaft, and the two shafts are coupled. In a second modification, the assembly is cantilevered by its drive shaft on the counterbalance shaft and is stabilized in coaxial relation therewith by a torque-reaction bracket. Such bracket may include a torque-limiting switch operable to reverse the drive in response to excess torque. For most installations, a down-drive cable is added to the counter-balance mechanism and connected to positively move the door from open to closed position in response to down-drive rotation of the counterbalance shaft.

    Abstract translation: 车库门开启器简单安装，并以最小的机制完全启动不同制造的各种平衡门，并作为紧凑套件进行包装和销售。 开启器围绕适于与门平衡轴的端部同轴联接的短主驱动轴构成。 驱动轴被安装在两个框架侧构件中，并且其间带有一个蜗轮和两个摩擦驱动盘，弹簧压靠在齿轮上，以将有限的驱动扭矩传递到轴上。 该齿轮由可在框架上滑动的载体上的电动机的轴上的蜗杆驱动。 手动凸轮使托架在用于驱动的​​蜗杆啮合位置和蜗杆脱离位置之间移动，以释放门以进行手动操作。 主轴的螺纹延伸部装有一对行进的螺母，其驱动开关以限制门行进两个方向。 在一个变型中，组件安装在安装板上的螺柱上并对其进行调节，以使驱动轴与平衡轴同轴，并且两个轴联接。 在第二变型中，组件通过其平衡轴上的驱动轴悬臂并且通过扭矩反作用支架与其同轴的关系稳定。 这样的支架可以包括扭矩限制开关，该转矩限制开关可操作以响应于过大的扭矩来反转驱动。 对于大多数安装，反向平衡机构中增加了一个下降驱动电缆，并连接起来，以响应于平衡轴的下降驱动旋转，将门从打开位置向闭合位置移动。
