用于真空吸尘器的电机组件。
专利摘要
一种真空吸尘器电机组件包括位于桶中的电机，配置为驱动风扇以提供气流。行星齿轮系统连接到电机的输出轴，以产生降低转速的输出。该输出用于通过皮带驱动搅拌器。皮带以比迄今可达到的更低转速驱动，因此皮带磨损减少。直接安装在电机壳体上的齿轮装置的设置提供了紧凑的组件。行星齿轮之一，如齿圈，被布置为在搅拌器卡住时相对于离合器构件滑动。如果滑动齿轮的摩擦热超过预定值，或者如果滑动齿轮以高于预定值的速度旋转，则致动器关闭电机。因此，在系统任何组件损坏之前，电机关闭。
Original abstractA vacuum cleaner motor assembly includes a motor in a bucket, configured so as to drive a fan to provide airflow. An epicyclic gear system is attached to the output shaft of the motor, to produce an output of reduced rotational speed. The output is employed to drive an agitator via a belt. The belt is driven at a reduced rotational speed to that achievable hitherto, and thus there is reduced wear on the belt. The provision of a gear arrangement mounted directly to the motor casing provides a compact assembly. One of the epicyclic gears, such as the ring gear, is arranged to slip with respect to a clutch member if the agitator becomes jammed. An actuator switches off the motor if the heat of friction of the slipping gear exceeds a predetermined value, or if the slipping gear rotates at a speed above a predetermined value. Thus, the motor switches off before damage occurs to any of the components of the system.
