Design and application of roller bearings in railway locomotive foundation brake gear
Aiming at the differences in structural types and load-bearing environments between roller bearings and conventional bearings,we proposed the load parameters and load-bearing capacity of roller bearings,and discussed the calculation methods for the effective rated load and maximum allowable load of roller bearings.The paper introduces the basic working principle of the brake caliper unit of the railway locomotive foundation brake gear,and the design,check and calculation of roller bearings in typical locomotive brake caliper units for the practical application.We conducted the targeted tests on the bearings in combination with the actual working environment of railway locomotives,which verifies the reliability of roller bearings in the actual working environment of locomotive foundation brake gear.
