Description
The European-style crane wheel set is the main mechanical part of the running mechanism. The European crane wheel requires the diameter of the wheel to be as small as possible, and generally adopts the bearing seat structure of the frame on the web, and the bearing seat is connected with the frame with fasteners, and the wheel pressure is relatively large, and the material strength and assembly accuracy are required to be higher.
Working Condition
1.Wheels manufactured by any processing method should be processed to eliminate internal stress (such as thermal stress that affects performance). Cast steel wheels should be annealed before machining to eliminate internal stress, and sand should be cleaned, casters and risers should be cut, and quality defects should be checked.
2.The surface roughness of the wheel tread and the inner side of the rim is Ra6.3 according to GB/T 1031-1995, and the surface roughness of the axle hole is Rn3.2.
3.Defects on the inner surface of the wheel tread and rim are not allowed to be repaired by welding
4.The cutting surface of the wheel should be coated with anti-rust oil, and all other surfaces should be coated with anti-rust paint.
5.Wheel vehicles should be surface quenched, and the structure should be refined before quenching. After heat treatment. The wheel surface condition should comply with the requirements in Table 17.1-106.
Features
FEATURE 1
The European crane wheel set is the main mechanical component of the operating mechanism. Due to the frequent forward and reverse operation, the wheels are required to be wear-resistant and have a relatively long service life.
FEATURE 2
Therefore, the tread should be as wide as possible during design, and the track should also use square steel to meet the matching requirements of the wheel tread. European wheels require the diameter of the wheel to be as small as possible.
FEATURE 3
Generally, the bearing seat structure is installed on the web of the frame. The bearing seat is connected to the frame with fasteners. It bears relatively large wheel pressure and requires relatively high material strength and assembly accuracy. High, with the characteristics of easy assembly and disassembly, simple maintenance and replacement, long service life and beautiful appearance.
