Structure and Components
The 45° split bearing box crane wheel assembly consists of four main parts:
- Wheel axle
- Crane wheel
- 45° split bearing housing
- Bearings
The split housing design allows the bearing box to be opened and serviced without removing the entire wheel assembly.
Materials and Manufacturing
- Cast steel: ZG55, ZG50SiMn, ZG42CrMo
- Forged steel: 60, 42CrMo, 65Mn
Material selection depends on load conditions and service requirements.
When to Use 45° Split Bearing Box Wheel Assemblies
This type of wheel assembly is typically used in crane systems operating under high load and requiring efficient maintenance access.
- Large lifting equipment with high wheel pressure
- Crane systems requiring frequent maintenance
- Heavy-duty travel mechanisms
- Applications where downtime must be minimized
Engineering Design Highlights
- The wheel is typically mounted at the end of the end beam web plate, reducing stress on installation bolts and improving structural reliability.
- The web plate is welded to a support ring, which provides better resistance to vibration and heavy loads compared to traditional side-mounted bolt connections.
- Due to limitations in alignment precision, self-aligning bearings are used to compensate for deviations during operation.
