Description
Technical field
The present invention relates to decelerator pulsation measurement, more particularly to a kind of internal spline expansion sleeve for being used to measure decelerator bounce
Structure.
Background technology
New-energy automobile is quickly grown in recent years, power set of the motor as new-energy automobile, is also obtained extensively
Concern.Existing motor has be difficult to prevent the problem of --- and motor abnormal sound, it is more to produce the influence factor of abnormal sound, its
The fit precision of middle motor and decelerator has a great influence to it.Motor is typically all to be connected by spline with decelerator, therefore
The machining accuracy of decelerator internal spline directly determines the reliability of motor operation.Currently used for measurement decelerator 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, connect using dial gauge and flange end face
Tactile form, end face run-out value when measurement flange rotates；By the way of lever meter contacts with the inner stopper on flange, measurement
Circular runout value when flange rotates.
The content of the invention
The present invention seeks to：A kind of internal spline swelling nested structure for being used to measure decelerator bounce is provided, improves measurement essence
Degree, simple in construction, cost is low, disassembly and installation facility, and measurement efficiency is high.
The technical scheme is that：
A kind of internal spline swelling nested structure for being used to measure decelerator bounce, including inner ring, outer shroud and axle；
The inner ring conehead that the inner ring includes interior ring flange and its side is fixedly connected, the interior ring flange are installed provided with inner ring
Hole；
The outer shroud taper hole that the outer shroud includes outer ring flange and its side is fixedly connected, the outer ring flange are installed provided with outer shroud
Hole；
The outer shroud taper hole is positioned in the internal spline of decelerator, and inner ring conehead and axle are put in outer shroud taper hole successively, inner ring peace
Dress hole is bolted fastening with outer shroud mounting hole.
Preferably, dismounting screwed hole is additionally provided with the interior ring flange, dismounting screwed hole is built with screw, screw front end
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 axle is fixedly connected with sucker, for adsorbing dial gauge and installation magnetic power meter.
It is an advantage of the invention that：
1. the decelerator internal spline measurement apparatus that the present invention provides new, deceleration is converted into by the measurement of internal spline machining accuracy
The measurement of device bounce, improve the precision of measurement.
2nd, the present invention has redesigned swelling nested structure on the basis of existing expansion sleeve, and have passed through test of many times, sends out
Now the structure meets the requirement of decelerator 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 means
Destructiveness and improve service life；The angular configurations of newly-designed expansion sleeve outer shroud taper hole angle and inner ring conehead are reasonable,
It can guarantee that and cause inner ring and axle, outer shroud and internal spline locking in the case of less screw torque, improve operability and inspection
Survey efficiency.

Embodiment
As illustrated in fig. 1 and 2, the internal spline swelling nested structure for being used to measure decelerator bounce of the invention, including sucker 1,
Axle 2, bolt 3, inner ring 4 and outer shroud 5.As shown in figure 3, the inner ring that the inner ring 4 includes interior ring flange 8 and its side is fixedly connected
Conehead 9, the interior ring flange 8 are provided with dismounting screwed hole 10 and inner ring mounting hole 11；As shown in figure 4, the outer shroud 5 is including outer
The outer shroud taper hole 13 that ring flange 12 and its side are fixedly connected, the outer ring flange 12 are provided with outer shroud mounting hole 14.
During specific installation, as illustrated in fig. 1 and 2, the internal spline 6 of outer shroud 5 and decelerator 7 originally coordinated for gap, first will be outer
Ring is put into internal spline 6, then installs inner ring 4 and axle 2, four bolts 3 is uniformly tightened with spanner, in the process outer shroud external diameter
Become larger, inner ring internal diameter tapers into, and when outer shroud can drive internal spline to rotate together, can meet requirement, now
Huge enclasping force is produced between inner ring and axle, outer shroud and internal spline, to realize being coupled for axle and internal spline, finally, by magnetic
