Abstract: An electrically driven linear actuator 1 has a motor housing 2 having an end fitting 3 with a thrust eye 4. The housing comprises an end plate 5 carrying the end fitting, a tubular body 6, a mounting plate 7 and a closure member 8. The mounting plate has six recesses 12 for receiving the output ends 15 of six gearboxes 16. Each gearbox has a respective axially-attached electric motor 17, fixed in place via its gearbox. Output shafts 18 from the gearboxes extend through the mounting plate into a recess 19 in the closure member 8.

Abstract: The linear actuator has a motor housing (1) of tubular stainless steel with an end cap (2), a motor (4) and epicyclic gearbox (6). The actuator has a telescopic arm (11), having an outer tube (12) and an inner tube (13) of stainless steel. The outer tube is removably attached to the motor housing. An extension screw (16) is provided in the arm with a driven end (16) journalled at the motor housing end (17) of the outer tube. At its inner end, the inner tube has threaded into it a plastics material nut (18), in which the screw engages. The end of the screw (16) has a clevis (23), open (24) axially away from the screw. The output shaft (7) from the gear box has a cross pin (31) through it. On each side of the shaft, the pin carries a respective roller (32), sized to fit in the clevis (23). The clevis and rollers form a dog clutch for transfer of drive from the gearbox to the extension screw. The telescopic arm is readily dismounted from the motor housing by unscrewing the disc (21) and axially withdrawing the clevis from the rollers.

Abstract translation: 线性致动器具有带端盖（2），马达（4）和行星齿轮箱（6）的管状不锈钢马达壳体（1）。 致动器具有伸缩臂（11），其具有外管（12）和不锈钢内管（13）。 外管可拆卸地连接到电动机壳体。 延伸螺钉（16）设置在臂上，该从动端（16）安装在外管的马达壳体端部（17）上。 在其内端，内管已经拧入塑料材料螺母（18）中，螺钉接合在其中。 螺钉（16）的端部具有沿轴向远离螺钉的开关（23），开口（24）。 来自齿轮箱的输出轴（7）穿过它的十字销（31）。 在轴的每一侧上，销承载相应的辊（32），其尺寸适于装配在U形夹（23）中。 U形夹和滚轮形成一个爪式离合器，用于将传动装置从变速箱传递到延伸螺杆。 通过旋转盘（21）并将U形夹从辊中轴向抽出，伸缩臂可以从马达壳体中轻松卸下。
