Crane Trolley Wheel Set

Description

The horizontal deviation value of the wheels of the crane operating mechanism is an important technical parameter of the crane. If the deviation value exceeds the tolerance, it will cause rail gnawing, increase running resistance, produce vibration and noise, intensify rail and wheel wear, and greatly reduce the service life of the crane. Therefore, all types of crane manufacturing technical conditions must specify the allowable value of the horizontal deviation of the wheels.

Wheel group structure: In application, controlling the horizontal deviation value of the running mechanism wheels is mainly achieved by taking corresponding technical measures based on different product structures. A commonly used and relatively simple design structure is to assemble the wheels onto a bracket to form a wheel group, such as an angle bearing box wheel group and a trolley type 45 ° split bearing box wheel group. On the main structure of the crane, install and adjust the wheel horizontal deviation appropriately before fixing it.

Features

1. The wheel group is a mechanical equipment composed of wheels, shafts, bearings, and bearing boxes. It is generally used to support a crane and load on a vehicle, and together on a designated track, it is a device that allows the crane to move back and forth.
2. The application of wheel sets is quite complex, and different skill methods are selected based on different product structures. However, the focus of the wheel group is still on controlling the horizontal deviation value of the working wheel group. A commonly used and relatively simple planning structure in daily work is to assemble wheels onto brackets to form a wheel group.
3. The composition of the wheel group is generally made of high-quality cast steel, because the common damage methods for wheels are wear, pitting, and crushing of the hardened layer. Therefore, in order to increase the wear resistance and service life of the wheel surface, materials with relatively solid and deep quenching are generally used.
