Tight tube structure.
Background technology
New-energy automobile is quickly grown in recent years, power set of the driving motor as new-energy automobile, is also obtained extensively
Concern.There are one the problem of being difficult to prevent for existing driving motor --- and motor abnormal sound, it is more to generate the influence factor of abnormal sound,
The fit precision of middle motor and retarder is affected to it.Driving motor is typically all to be connected by spline with retarder, therefore
The machining accuracy of retarder internal spline directly determines the reliability of motor operation.Currently used for measurement retarder internal spline processing
The device of precision is less, and complicated, inconvenient for operation, and efficiency is low.
Most domestic Automobile Parts Industry in main gearbox assembly assembling, is connect using dial gauge and flange end face
Tactile form, end face run-out value when measurement flange rotates；In a manner that lever meter is contacted with the inner stopper on flange, measurement
Circular runout value when flange rotates.
Utility model content
The utility model aim is：A kind of internal spline swelling nested structure for being used to measure retarder bounce is provided, improves and surveys
Accuracy of measurement, simple in structure, at low cost, disassembly and installation facility, measurement efficiency are high.
The technical solution of the utility model is：
A kind of internal spline swelling nested structure for being used to measure retarder bounce, including inner ring, outer shroud and axis；
The inner ring conehead that the inner ring includes interior ring flange and its one side is fixedly connected, the interior ring flange are equipped with inner ring
Mounting hole；
The outer shroud taper hole that the outer shroud includes outer ring flange and its one side is fixedly connected, the outer ring flange are equipped with outer shroud
Mounting hole；
The outer shroud taper hole is positioned in the internal spline of retarder, and inner ring conehead and axis are put in successively in outer shroud taper hole, interior
Fastening is bolted with outer shroud mounting hole in ring mounting hole.
Preferably, dismounting threaded hole is additionally provided on the interior ring flange, screw, screw front end are housed in dismounting threaded hole
Outer shroud flange surface is contacted, by the rotation of screw, inner ring conehead is extracted out out of outer shroud taper hole.
Preferably, the upper end of the axis is fixedly connected with sucker, for adsorbing dial gauge and installation magnetic power meter.
The utility model has the advantages that：
1. the retarder internal spline measuring device that the utility model provides new turns the measurement of internal spline machining accuracy
The measurement of retarder bounce is turned to, improves the precision of measurement.
2nd, the utility model has redesigned swelling nested structure on the basis of existing expansion sleeve, and have passed through multiple examination
It tests, it is found that the structure meets the requirement of retarder pulsation measurement device.Newly-designed expansion sleeve outer annular diameter value is proper,
So that outer shroud is easily put into internal spline, and outer shroud is with that after internal spline locking, will not damage internal spline, reduce the detection
Device destructiveness and improve service life；The angular configurations of newly-designed expansion sleeve outer shroud taper hole angle and inner ring conehead close
Reason can guarantee in smaller screw torque so that inner ring and axis, outer shroud and internal spline locking, improve operability and
Detection efficiency.
