Abstract

A device for measuring the bearing friction moment, comprising a housing, a drive shaft coaxially mounted therein with a mandrel at the end for fastening the inner ring of the measured bearing and a seat for accommodating the outer ring of the bearing, a torque meter associated with the socket, a loading mechanism communicating with the source working environment, characterized in that, in order to increase the reliability of measurement by simulating the operating conditions of bearings, the loading mechanism is designed as mounted on the body coaxially the shaft of the cup with two diametrically located openings for communication with the source of the working medium and placed therein and in contact with the end of the disc slot with radial protrusions on the free end facing the bottom of the cup and dividing the cavity of the cup into two parts forming the air support for the disc.

Description

The invention relates to a testing technique and can be used to measure the bearing friction moment.

The aim of the invention is to noBbmie the reliability of measurements by simulating the operating conditions of bearings.

The drawing shows a diagram of a device for measuring the bearing friction moment.

The device comprises a housing 1, a drive shaft 2 coaxially mounted thereto with a mandrel 3 for fastening the inner ring of the bearing 4 to be measured;

There is an outer ring of the bearing 4 and a loading mechanism, made in the form of a cup 6 with two diametrically located openings 7 and 8 for communicating with the lines 9 and 10 communicated with a source (not shown) of the working medium placed in it and contacting the slot 5 a disk 11 with radial protrusions 12, 13 at the end, dividing the cavity of the cup 6 into two parts, and a torque meter 14 connected to the socket 5.

The device works in a dim way.

In the initial state, the measured bearing 4 is installed in the socket

5, is fixed on the mandrel 3 and set the torque gauge 1D to zero. When measured with the help of trains 9 and 10, the working medium is fed into the openings 7 and 8 of the cup 6 and in the cavities of the cup 6, different pressure values are generated, which through the disk 11 and

nest 5 load bearing 4 axial and torque workloads. Then the operating speed is reported to the drive shaft 2, while measuring the bearing friction moment with the help of the torque meter 14.
