Key Specifications/Special Features:
As a technical department in charge of bearing industry, Luoyang Bearing Research Institute has rich experience and plentiful scientific payoffs in the study of basic theory and application technology of rolling bearing, design and application of various special and general bearings. The institute had undertaken a batch of projects such as “CAD of General Bearings”, “Design of Key Bearings for Medium to Large-scale Wind Turbine Generator Set”, “Research and Industrialization Engineering of Vibration and Noise Reduction in Deep Groove Ball Bearing”, “FEA of Convexity of Tapered Roller Bearing”, “Study of Life Extension Technology for Front Hub Bearing of SANTANA”, “FEA of Tapered Roller Bearings for Cargo Train”, which are all national, provincial and industrial key scientific and technological projects, and got a batch of important technological achievements. In products, the institute did comprehensive and systematical research of automobile hub bearing, clutch release bearing, constant velocity joints, gearbox bearing, motor bearing and air conditioner bearing. Axle box bearing bears extreme load between wheel set and bogie truss, and it should meet different kinds of technical requirements. By cooperating with locomotive manufacturers, our company can develop optimized axle box bearings which apply to actual operation circumstance, and assess the performance test based on DIN EN standard. Developed products are as follows:Axle box bearings for high-speed railway with speed of 250km/h and 350km/hAxle box bearings for speed-up passenger trainAxle box bearings for diesel and electric locomotiveAxle box bearings for metro and urban rail vehicleAs a bearing unit, double-row tapered roller bearing in axle box of high-speed railway has a complete seal, its grease should be put away (packed) and clearance be adjusted before assembly.Usage requirements of high speed, long life and high reliability can be meted by designs as follows:High-performance material and special heat treatment technology, to ensure bearing’s high performanceEnhanced design, to improve bearing’s load capacity and prolong its life
Shape modification of contour curves of roller and raceway, match optimization design, to get the best distribution of contact stress
Optimization design of rib and spherical basal plane (base), to increase film formation ability and improve lubrication condition
Special design of cage and optimized riding land, to make bearing adapted to more challenging running condition
Improving precision class and reducing friction, to make bearing adapted to higher running speed
Reliable lubrication and high-performance seal
By certification [File Integrity]
