The influence of sight factor, measurement error is bigger, poor repeatability；By nut check, the axially loaded of double-row bearing is realized, it can not
The axial load applied is quantitatively evaluated.
Utility model content
The utility model will solve the disadvantage that the above-mentioned prior art, and it is simple to provide a kind of structure, detect more accurate circular cone
Roller bearing starts moment of friction detection device.
The utility model solves the technical solution of its technical problem use: this tapered roller bearing starting moment of friction inspection
Device is surveyed, mainly includes column experimental bench, bearing block and bearing holder (housing, cover), bearing holder (housing, cover) is located at the top of bearing block, detected circular cone
Roller bearing is fixed with detection components between bearing holder (housing, cover) and bearing block on column experimental bench, detection components and bearing holder (housing, cover) it
Between be connected with rope.
The detection components include pulley blocks, cross bar, hanging basket and counterweight, and pulley blocks are fastened on column reality by cross bar
It tests on platform, one end of rope passes through skidding group and connects hanging basket, and the other end is connected on bearing holder (housing, cover), and counterweight is placed in hanging basket.
The outer diameter of the bearing holder (housing, cover) is equipped with groove, and rope is fixed on groove.
The top of the bearing holder (housing, cover) is equipped with load block.
This tapered roller bearing starts moment of friction detection method, including above-mentioned detection device,
Firstly, the tapered roller bearing of test is mounted between bearing block and bearing holder (housing, cover), and added with negative on bearing holder (housing, cover)
Lotus block；
Then, rope being wound in bearing holder (housing, cover) outside diameter mill and passing through pulley blocks, the other end of rope connects hanging basket 8；
Finally, add counterweight on hanging basket, and when counterweight is added to constant weight, under the drive of rope, tapered roller bearing
It starts turning, at this point, counterweight weight G1+ hanging basket weight G2, for the weight G for making bearing rotate,
According to G value, can be with calculated load M by formula (1) under the action of, the starting moment of friction of bearing:
T=G × L (1)
Wherein, L is bearing holder (housing, cover) groove radius；M=load block total weight M1+ bearing holder (housing, cover) weight M2.
The payload M realizes by adjusting the quantity of load block, size.
The utility model has the advantages that: the utility model can be realized single-row tapered roller bearing starting moment of friction
Measurement；Measurement error is small, and repeatability and stability are good；Can be under quantitative axial load, single-row tapered roller bearing starts
Moment of friction carries out precise measurement.
Detailed description of the invention
