Description
редного зуба и дальнейшее д& жение щетки и ее вылет из щеткодержател предотвращаетс . Поскольку отогнутый конец нажимного элемента выполнен пружин щим, он амортизирует жесткие удары, имеющие место при осуществлении таким образом механизма храпового останова.the abrasive tooth and further brushing and its departure from the brush holder is prevented. Since the bent end of the pressure element is spring-loaded, it absorbs the hard shocks that occur during the implementation of the ratchet-stop mechanism.
Предложенна конструкци не имеет амортизирующих прокладок между щеткой и нажимным элементом и на конце нажимного элемента, упирающемс в торец зуба, с целью добавочного дешифровани вибраций.The proposed design does not have cushioning pads between the brush and the pressure element and at the end of the pressure element, which abuts against the end of the tooth, in order to further decipher the vibrations.
Конструкци проста в изготовлении и надежна в эксплуатации.The design is easy to manufacture and reliable in operation.
Предмет изобретени Subject invention
Щеточный узел электрической машины, содержащий обойму щеткодержател , подвижную щетку, нажимной элемент и узел храпового останова, сопр женный с нажимным элементом, отличающийс тем, что, с целью повышени надежности, узел храпового останова выполнен на стенке обоймы щеткодержател в виде р-ейки с несимметричными зубцами, а свободный конец нажимного пружин щего элемента отогнут в сторону, противоположную направлению усили его пажати на щетку и введен в зацепление с указанными зубцами.A brush unit of an electric machine, comprising a brush holder, a movable brush, a pressure element and a ratchet stop assembly, mated with a pressure element, characterized in that, in order to increase reliability, the ratchet stop assembly is made on the wall of the brush holder in the form of un-symmetrical edges teeth, and the free end of the pressure spring element is bent in the direction opposite to the direction of its force on the brush and is engaged with these teeth.
