DRS walking wheel set that makes the crane reciprocate on the track
DRS Walking Wheel group definition:
Wheels are used to support cranes and loads, and to make the crane reciprocate on the track. The main forms of wheel damage are wear, hardened chipping and pitting. The material of the wheel is generally ZG430-640 cast steel. In order to improve the wear resistance and life of the wheel surface, the tread surface should be heat-treated. The surface hardness is HB300-350, and the quenching depth is not less than 20mm.
DRS Wheel group structure:
In the application, the control of the horizontal deflection of the wheels of the operating mechanism is mainly based on the adoption of corresponding technical measures based on different product structures. The more common and relatively simple design structure is to assemble the wheels on the bracket to form a wheel set, such as an angular bearing box wheel set and a trolley-type 45 ° split bearing box wheel set. On the main structure of the crane, install After adjusting the wheel's horizontal deflection, it is fixed.
