软启动装置及刮板输送机
摘要：
本实用新型提供了一种软启动装置和刮板输送机，其中，软启动装置包括壳体、主动轴、从动轴、主动摩擦部件、从动摩擦部件、永久磁铁、电磁铁和充满壳体内腔的磁流变脂；其中，主动轴从壳体的一端插入、与设置于壳体内部的主动摩擦部件固定连接，带动主动摩擦部件一起旋转；从动轴从壳体的另一端插入、与设置于壳体内部的从动摩擦部件固定连接，由从动摩擦部件带动一起旋转；在壳体两端部的内侧分别设置永久磁铁，在壳体两端部外侧分别设置电磁铁；该电磁铁通电后产生的磁场，与设置于壳体同一端内侧的永久磁铁产生的磁场方向相反。本实用新型提供的软启动装置结构简单、方便控制和维护、制造成本低、传递扭矩效率高且连续可调。
摘要（英）：

The utility model provides a soft starting device and a scraper plate conveyor, wherein, the soft starting device comprises a housing, a driving shaft, a driven shaft, a driving friction part, a driven friction part, permanent magnets, electromagnets, and magneto rheological grease filling the core space of the housing; wherein, the driving shaft inserts from one end of the housing, is fixedly connected with the driving friction part disposed in the internal of the housing, and drives the driving friction part to rotate together; the driven shaft inserts from one end of the housing, is fixedly connected with the driving friction part disposed in the internal of the housing, and is driven by the driving friction part to rotate together; a permanent magnet is respectively disposed at the internal sides of the two end parts of the housing, an electromagnet is respectively disposed at the external sides of the two end parts of the housing; a magnetic field generated through electrification of an electromagnet is in an opposite direction to a magnetic field generated by the permanent magnet at the internal side of the same end of the housing. The soft starting device is advantaged by simple structure, facilitation of control and maintenance, low manufacture cost, high efficient and continuously adjustable transmission torque.
