Abstract

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.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to a friction coupling for a branch road switch machine. Background technique [0002] The electric switch machine friction coupling is a coupling device that protects the motor and absorbs the moment of inertia. Its functions: First, when the motor control circuit is cut off, the motor cannot stop rotating immediately, and the electric switch machine friction coupling makes the connection with it The output stops moving. The second is to prevent the motor from idling for a long time and burning out when the switch rail is blocked and cannot continue to switch. [0003] When the new electric switch machine operates, its motor is decelerated by gears, which drives the friction coupling to rotate. The friction coupler is connected with the ball screw through a flat key, thereby driving the ball screw to rotate, and the screw nut on the ball screw drives the push plate sleeve to perf...
