Wheel couple is one of the main parts in the car. Wheel couple provides the direction of the movement on a railway line and assumes all loadings which are transferred as from the car to rails, and back. Traffic safety of trains in many respects depends on materials and a design, the production technology, repair of wheel couples. Important value has also survey of wheel couples. The design of wheel couples, their operational state exert huge impact on smoothness of the course of structure, size of forces which arise at implementation of interaction of the car and a way, resistance to the movement.
Usually wheel couples do by "deafs" that means a rigid nasazhivaniye of wheels on an axis in the press way. In that case the design is very reliable. Main defects of wheel couples: wear and weakening of a bandage of wheel couples, rams, undercut of a crest, hollow, crack, dent, splitting off of a cogwheel, wheel center, crack and dent, risks, zaboina. The unsatisfactory condition of wheel couples makes a serious threat to security on the railroad therefore we can safely speak about extreme need to watch a condition of details and in time to carry out repair of wheel couples.
Wheel couple has to conform to the following requirements: in combination with axle boxes to create the smallest sodvizheniya; such quality as elasticity allows to provide decrease in noise level, mitigation a tprotivleniye at olchok; wheel couple, having the minimum weight, has to be very strong.
Wheel couples are formed by means of the special machines intended for processing of axes and wheels; bridge, console cranes; hydraulic press; the stands providing a defektoskopirovaniye of axes, etc.
To ensure traffic safety on the railroads, there are state standards establishing tough rules of technical operation of JSC RZhD which regulate process of repair and survey of wheel couples, and also a way of their formation and operation. Different types of periodic repair of wheel couples are established: capital, local, current. Repair of wheel couples is made in depot and at car-repair plants.
Our organization carries out services which will help you to support wheel couples in a worthy state, namely:
- sale of spare parts for freight cars;
- sale wheel PARSONK (old axis, new wheel) and NONK (new axis, new wheel);
- repair of spare parts for freight cars;
- repair of wheel couples of COHK and HOHK.
