The invention relates to the technical field of traffic, and discloses a friction coupling for a turnout switch machine. The friction coupling comprises a speed reduction shell, an inner gear is arranged on the surface of the speed reduction shell, an output shaft is sleeved with the middle of the inner gear, and friction brake plates are arranged at the outer side of the inner gear. The number ofthe friction brake plates is two, and one ends of the friction brake plates are fixed to a clamping plate shaft of the speed reduction shell. Through the attraction or repulsion effect of a force application structure, the extrusion force of the friction brake plates acting on the inner gear is increased or decreased, so that the purpose of increasing or decreasing the friction force between a friction belt and the inner gear is achieved, the torque transmitted to the output shaft by a motor is increased in a normal state, and when a turnout is blocked, the abrasion of the friction belt caused by the inner gear is reduced, the adjustment frequency of the friction coupling is reduced, the labor investment is reduced, the service life of the friction belt is prolonged, and the production and maintenance cost is reduced.
本发明涉及交通技术领域,且公开了一种岔道转辙机用摩擦联结器,包括减速壳,所述减速壳的表面设置有内齿轮,所述内齿轮的中部套接有输出轴,所述内齿轮的外侧设有摩擦制动板,所述摩擦制动板的数量为两个且摩擦制动板的一端固定于减速壳的夹板轴上。本发明通过施力结构的吸引或者排斥作用,增大或者减小摩擦制动板作用在内齿轮上的挤压力,从而达到增大或者减小摩擦带与内齿轮之间的摩擦力的目的,在正常状态下,提高电机传输至输出轴上的扭矩,在道岔受阻时,降低内齿轮对摩擦带的磨损,达到减少对摩擦联结器的调整次数,降低人力的投入,同时也延长了摩擦带的使用寿命,降低生产及维修的成本。
