Abstract

The invention discloses a vertical rolling bearing equivalent friction coefficient measuring device. The vertical rolling bearing equivalent friction coefficient measuring device comprises a machine body, a sliding table, a mandrel, two bearing pedestals, a rotating speed sensor and a data acquisition / processing / calculation / display device, wherein one of the bearing pedestals is fixedly connectedwith the machine body, and the other one is fixedly connected with the sliding table; an A to-be-tested rolling bearing outer ring is arranged on a bearing pedestal shoulder which is fixedly connectedwith the machine body, and a B to-be-tested rolling bearing outer ring is arranged on a bearing pedestal shoulder which is fixedly connected with the sliding table; an A to-be-tested rolling bearinginner ring is arranged on the shaft shoulder at one end of the mandrel, and a B to-be-tested rolling bearing inner ring is arranged on the shaft shoulder at the other end of the mandrel; the sliding table is capable of horizontally moving along the axial direction of the inner cylindrical surface of the bearing pedestals under the guide of a guide component; and the data acquisition / processing / calculation / display device is used for collecting and processing the angular speed signal, monitored by the rotating speed sensor, of the mandrel, and calculating the equivalent friction torque and equivalent friction coefficient of the tested rolling bearing. The measuring device has the capability of rapidly and precisely measuring the equivalent friction torque and equivalent friction coefficientof the rolling bearing.

Description

technical field [0001] The invention belongs to the technical field of testing the friction energy consumption characteristics of rolling bearings, and relates to a device and method for measuring the equivalent friction coefficient of vertical rolling bearings. Background technique [0002] The friction energy consumption during the operation of rolling bearings directly affects the heating, temperature rise and wear of bearings, which in turn affects the performance and life of rolling bearings. The friction energy consumption characteristic of rolling bearing is an inherent characteristic of rolling bearing itself, which reflects the manufacturing quality and cleanliness of rolling bearing to a certain extent. [0003] At this stage, starting friction torque and rolling friction torque are used to evaluate the starting friction energy consumption and rolling friction energy consumption of rolling bearings respectively, and various rolling bearing friction torque measuring...
