本发明涉及调整用于卧或坐在安装在可移动家具部件的类型的双驱动器的电动马达的直线驱动装置。 电动机线性驱动经由相应的蜗轮驱动以（Hubelement），2块螺纹轴的被在纵向对齐（2，3）每个往复运动元件的运动，以及与每个螺杆 并且在这两个设置的轴承的轴的端部（2,3）。 配置在轴的至少一个附近的另一端部的轴承被设计成一个滚动轴承（4，5）具有外部支承环（7）和内轴承环（6）。 本发明的目的实现了短的结构，和是设计的电动马达的双驱动装置，从而提高结构的强度和稳定性。 解这个目的是通过将在其之间接受在靠近轴向端部彼此，只有两个滚动轴承支座（Wiederlager）实现（4，5）。 滚动轴承（4，5），从两侧在接收表面支撑到彼此。 点域1

【Task】
The present invention relates to an electric motor linear drive unit of the dual drive of the format that you want to adjust the components mounted on a movable furniture for lying or sit. Electric motor linear drive is driven through each worm gear for movement of each reciprocating element (Hubelement), 2 pieces of threaded shaft that is aligned in the longitudinal (2, 3), and with each screw and a bearing provided at both ends of the shaft (2, 3). Bearings disposed at the end of the shaft proximate at least one another is designed as a rolling bearing (4, 5) having an external bearing ring (7) and the internal bearing ring (6). The purpose of the present invention achieves a short structure, and is to design an electric motor dual drive device so as to improve the strength and stability of the structure.
A
This object is achieved by placing the abutment (Wiederlager) between which accepted the shaft end in close proximity to each other, only two rolling bearings (4, 5). Roller bearing (4, 5) are supported from both sides to each other in the receiving surface.
