  • Calculation verification

    Independently develop engineering algorithm software

    A bearing calculation and analysis software platform has been developed based on standards such as DG03, ISO76, ISO281, and TS16281, which can quickly perform the following calculations: bearing load distribution, raceway contact stress, roller repair stress distribution, quenching layer depth, service life, raceway fatigue damage, etc.

    Finite element verification

    Based on conventional FEA related software such as Ansys and Romax, secondary development is carried out to establish a finite element calculation platform, realize modeling, pre-processing command flow, result extraction and processing, standardize programming, conduct systematic analysis of bearing inner and outer rings, bolts and other related connection structural components, and perform static strength verification and fatigue damage verification of bearings.

  • 6-meter diameter test bench

  • 20MW level spindle bearing test bench

    The latest 20MW level spindle bearing test bench can be used to build a complete shaft system for testing main bearings (such as SRB, TRB, etc.) and related components (such as spindle, bearing seat, gearbox bearings, etc.). 2024 testing plan: January SRB, March TRB

    Can build a main bearing test bench for shaft testing

    Overturning moment 60000kNm, axial and radial forces 10000kN, maximum outer diameter 5500mm; More closely related to the actual working conditions of the main bearing, conducting accelerated fatigue testing and design verification.

  • Research and development of spindle bearings

    Over 30 years of technological accumulation, international first-class design standards, intensive testing and experimentation

    Using surface induction hardening: the development and research of spindle bearings such as TRB, SRB, DTRB, 3CRB, etc., from full transmission chain system simulation and forward design, to high-precision machining and manufacturing, and then to sufficient bench testing, ensure the high reliability and long life requirements of the product

    Configure 4 6-meter no soft strip quenching machine tools

    The three row roller spindle bearings have been supplied in bulk and have been in operation for 3+years; The sample has passed the Xiangdian docking test and the temperature has stabilized at 66.9-71.1
