Detailed Product Description

1.Wheel to the axle
2.They are composed of the bearings and wheel bearing housing group.

      Wheel to the axle, bearings and wheel bearing housing and other components group. Wheel is used to support cranes and load, and in orbit to make crane moving back and forth to run the device. Major damage in the form of wheel wear and pitting crushed hardened layer. The material generally used wheel ZG******0 cast steel. In order to improve strength and wear-resistant surface of the wheel life, tread surface heat treatment should be to require the surface hardness of HB******0, quenching depth of not less than *0mm.
      Crane level institutions wheel crane skew values are important technical parameters, deflection value will cause skew tolerance, increased running resistance, vibration and noise, increased rail and wheel wear and greatly reduce the service life of crane, crane manufacturing all kinds of conditions so the wheel must be allowed provided the level of skew values.
      Application level control wheel deflection value of the operating agencies are mainly based on different product structure to take appropriate technical measures. More common, process measures are relatively simple design structure is: The composition of the wheel assembly to the bracket on the wheel group, for example, the wheel bearing housing angle group and the *5 ° split trolley wheel bearing housing group, the main structure of the crane, the installation the level of the right wheel to adjust after the fixed skew.
