AI Technical Summary
In the existing assembly method of heavy-duty wheel hub bearing frame assembly, the traditional theoretical dimension calculation and tolerance superposition lead to cumulative errors, resulting in unqualified clearance. Moreover, repeated disassembly, grinding and adjustment are time-consuming and labor-intensive, affecting production cycle and equipment reliability.
By employing a step-by-step measurement and geometric reverse calculation method, the specific dimensions of the housing and bearings are measured, and spacers with matching thickness are calculated and machined to achieve high-precision assembly, avoid cumulative errors, and ensure that each bearing row can bear loads as required by design.
It effectively overcomes the problem of clearance control inaccuracy caused by cumulative errors, improves assembly efficiency and consistency, ensures the high rigidity and anti-eccentric load performance of bearings, extends service life, and ensures the safety and reliability of heavy equipment.
