Utility model content
When the purpose of this utility model is for solving the detection of current bearing rotation precision, the weight by load block separately designs processing to the running accuracy measurement load block realizing the applying of axial load, inner ring and outer ring.Two set load block processing and manufacturings respectively, twice clamping during measurement, load block axis is big with the coaxiality error of bearing axis, and bad measurement repeatability, measurement error is big.Measure burden requirement for meeting simultaneously, need great load block size, cause the waste of material, the problem increasing processing cost, it is provided that a kind of solid box running accuracy is measured and used load block.
This utility model is the deficiency solving above-mentioned technical problem, be the technical scheme is that
nullA kind of solid box running accuracy is measured and is used load block，Including multidiameter shaft，Shoulder hole is offered in big footpath section in multidiameter shaft，It is machined with multidiameter in path section in multidiameter shaft，The external cylindrical surface of described multidiameter shaft diameter of axle largest segment constitutes locating and machining basic circle cylinder，Inner peripheral surface and the inner face vertical with this inner peripheral surface of the path section in described shoulder hole cooperate and constitute shoulder hole auxiliary surface，The inner peripheral surface of the big footpath section in shoulder hole constitutes the cooperation face of cylinder, outer ring，The end face of the path section in vertical with the inner peripheral surface of the big footpath section in shoulder hole and close shoulder hole constitutes outer ring positioning reference plane，The outer circumference surface of the path section in multidiameter shaft two ends and the end face of the multidiameter shaft vertical with this outer circumference surface cooperate and constitute multidiameter auxiliary surface，The outer circumference surface of the path section of multidiameter constitutes inner ring and coordinates the face of cylinder，The end face of the multidiameter vertical with the outer circumference surface of the path section of multidiameter constitutes inner ring positioning reference plane，The face of cylinder is coordinated by inner ring、The measurement of the inner ring running accuracy that cooperated of inner ring positioning reference plane and multidiameter auxiliary surface，The face of cylinder is coordinated by outer ring、The measurement of the outer ring running accuracy that cooperated of outer ring positioning reference plane and shoulder hole auxiliary surface.
Described locating and machining basic circle cylinder carries out annular knurl process and accidentally injures operator to prevent load block from use skidding.
When measuring outer ring running accuracy, bearing inner race is fixed, the ladder nose end clamping of this load block is on bearing outer ring surface, the cooperation face of cylinder, outer ring forms matched in clearance with bearing outer ring, outer ring positioning reference plane is by outer ring datum level good location, retainer and inner ring are fixed by the design of shoulder hole auxiliary surface in order to prevent outer ring positioning reference plane wide, affect the normal rotation of bearing.During use, operator rotates load block by hand, due to inertia force effect thus drive bearing outer ring rotate realize measure.When measuring inner ring running accuracy, bearing outer ring is fixed, the ladder axle head clamping of this load block is on bearing inner race surface, inner ring coordinates the face of cylinder to form matched in clearance with bearing inner race, inner ring positioning reference plane is by inner ring datum level good location, retainer and outer ring are fixed by the design of multidiameter auxiliary surface in order to prevent inner ring positioning reference plane wide, affect the normal rotation of bearing.During use, operator rotates load block by hand, due to inertia force effect thus drive bearing inner race rotate realize measure.Four running accuracy parameters of a set of bearing can complete to measure by twice clamping, and load block is good with bearing proper alignment, and measurement reproducibility is high.Locating and machining basic circle cylinder carries out annular knurl process simultaneously, and operator can prevent load block from skidding and accidentally injuring oneself in use.
The beneficial effects of the utility model are: it is simple that this utility model in use has processing, and machining accuracy is high, and low cost is simple to operate, measure efficiency high, and indicating value is reproducible, the advantage of convenient management.
