涡轮蜗杆式传动开关
摘要：
一种涡轮蜗杆式传动开关，包括第一蜗轮、第二蜗轮和蜗杆，所述蜗杆的两端设有齿形段，所述蜗杆的中部为平直段，所述第一蜗轮可转动地安装在自动转换开关的基座本体的一端，所述第二蜗轮可转动地安装在所述基座本体的另一端；所述蜗杆同时与第一蜗轮和第二蜗轮啮合，所述蜗杆与用以推动蜗杆往复运动的驱动机构连接，所述第一蜗轮与自动转换开关设备的第一动触头联动，所述第二蜗轮与自动转换开关设备的第二动触头联动。本发明构简单、防冲击振动能力强、触头分合时冲击力较小、弹跳少，大大提高工作的可靠性。
摘要（英）：

A turbo-worm transmission switch comprises a first worm gear, a second worm gear and a worm. The two ends of the worm are provided with tooth-shaped sections, the middle portion of the worm is a straightness section, the worm is engaged with the first worm gear and the second worm gear, the worm is connected with a drive mechanism configured to push reciprocating motion of the worm, the first wormgear is linked with a first moving contact of an automatic conversion switching device, and the second worm gear is linked with a second contact of the automatic conversion switching device. The turbo-worm transmission switch is simple in structure, high in impact and vibration resistance capacity, small in impact when the contacts are connected and disconnected and little in bounce and greatly improves the work reliability.
