Transmission bearing types and technical requirements

1 Bearing Type
(1) spindle bearings: generally spherical roller bearings, also using a large cone angle double row tapered roller bearings.
(2) generator bearings: deep groove ball bearings, cylindrical roller bearings.
(3) gearbox Backing bearings  deep groove ball bearings, cylindrical roller bearings, full complement cylindrical roller bearings, double row tapered roller bearings, spherical roller bearings, spherical roller thrust bearings, four point contact ball bearings.
2 Technical requirements
From a structural point of view the bearing drive mostly standard bearing types, the difference is that, in order to ensure high reliability, the material, the heat treatment made ??a number of specific requirements.
(1) rings and rolling elements commonly used ESR smelting ZGCr15 or ZGCr15SiMn bearing steel manufacturing, the quality of heat treatment should be consistent with ZJB J11 038-1993 "military high carbon chromium bearing steel bearing parts heat treatment quality requirements" requirement.
(2) of the bearing parts for high-temperature tempering treatment to remove excess residual austenite, stable parts dimensional accuracy; ensure that the temperature difference between the larger environment bearing high reliability operation.
