Clutch for switch machine and electric switch machine
The embodiment of the invention discloses a clutch for a switch machine and the electric switch machine. The clutch for the switch machine comprises a rotor provided with a hysteresis ring; a stator to which a permanent magnet is mounted; and a bearing connecting the rotor and the stator; when the current load of the switch machine is smaller than a set load, the rotor and the stator can be driven by a power source of the switch machine to synchronously run, and torque is transmitted through magnetic torque between the hysteresis loop and the permanent magnet. When the current load of the switch machine is larger than the set load, the rotor and the stator can be driven by a power source of the switch machine to rotate relatively, the hysteresis ring is magnetized repeatedly by the permanent magnet, and stable hysteresis torque is generated. According to the technical scheme, a non-contact slipping mode is adopted, so that no abrasion exists between the stator and the rotor, and the fatigue resistance is good.
本申请实施例中公开了一种转辙机用离合器和电动转辙机。其中，转辙机用离合器包括：安装有磁滞环的转子；安装有永磁铁的定子；和连接所述转子和所述定子的轴承；其中，当所述转辙机的当前负载小于设定负载时，所述转子和所述定子能够在所述转辙机的动力源的驱动下同步运转，依靠所述磁滞环和所述永磁铁之间的磁力矩来传递扭矩；当所述转辙机的当前负载大于设定负载时，所述转子和所述定子能够在所述转辙机的动力源的驱动下相对转动，所述磁滞环被所述永磁铁反复磁化，产生稳定的磁滞力矩。本申请实施例中的技术方案由于采用非接触式的打滑方式，因此定子转子间无磨损，耐疲劳性好。
