Design and Analysis: Analog design experience is still the main study stress analysis and load spectrum is almost blank. Technical difficulties which are the requirements for spindle bearings trouble-free operation of 13 * 104h or more, and have more than 95 percent reliability; gearbox bearings for high load capacity design a high failure deep groove ball bearing rate and so on.
Materials: different parts of the bearing using different materials and heat treatment, such as increased yaw and pitch bearings 40CrMo steel at low temperature (ambient temperature -40 ℃ ∽-30 ℃, the bearing operating temperature of about -20 ℃) and other mechanical impact energy heat treatment method performance control surface induction hardening of the hardened layer depth, surface hardness, soft bandwidth and surface cracks; gearbox bearing equivalent foreign STF, HTF steel research and control its optimum content of residual austenite research; spindle bearing quality steel in the domestic vacuum degassing surviving in the case of a gap, using ESR carburizing steel ZG20Cr2Ni4A manufacturing.
Anti-corrosion and slewing rings sealing.
Yaw and pitch bearing special clearance requirements.
Yaw and pitch bearing raceways grinding.
spindle bearings and gearbox bearings precision machining.
Transmission bearings maintain improved design frame.
Testing and so on.
