NO1(China) Power Equipment Co. Ltd

Model Number: HH221440 Brand Name: NO1 Key Specifications/Special Features: Key specifications/special features:Railway locomotive vehicle bearing used in locomotive and vehicle of bearings. On the locomotive bearing including axle box bearings, bearings, traction motor bearings, transmission system power plant bearing and the bearing of the cooling system, and bearing is the main axle box bearing on vehicles, passenger car axle box multi-purpose short cylindrical roller bearing, truck axle box mainly adopts circular cone roller bearings, vehicles bearing the varieties, structure, performance and other basic similar to locomotive axle box bearing.1. The axle box bearingLocomotive wheel through the axle box connected to the locomotive car-body, springs and bogie frame, axle box bearing of locomotive spring directly under the gravity of the wheel and rail of the radial, axial impact, in addition to passing the traction and produce some of the additional load, and enough so axle box bearing to have larger bearing capacity, can impact resistance vibration, must have a higher life, safety and reliability, small size and quality. To facilitate inspection and maintenance, locomotive bearing, therefore, often with non-standard series of bearings and special bearings technical conditions, the commonly used rolling bearing has the following three categories.(1) Cylindrical roller bearing internal combustion engine cars and electric locomotives most axle box adopts the cylindrical roller bearing. Basically has the following two.1) The four row cylindrical roller bearingsThe locomotive axle box bearing early adoption and loading is the largest number of four row cylindrical roller bearing type 972832.The high bearing capacity, the life is long, its rated dynamic load of 1445kn. Because only can bear radial load, unable to bear axial load, so must be up to bear axial force within the axle box of the device.2) Double row cylindrical roller bearingsThe east is red 2, 3, 5, 21 and Beijing locomotive axle box adopts double row cylindrical roller bearing 982832 t, radial force and the bearing and angular contact ball bearing 146132 t carry axial load.(2) Spherical roller bearings
Using the advantage of spherical roller bearing is in between the axle box and bogie frame cannot tilt compensation device. Type of China's imports from Romania ND2 diesel locomotive axle box bearings SKF bearing company is a production of C type spherical roller bearing.
