Embodiment
Below with reference to accompanying drawing, the present invention is described in detail, as shown in the figure：The gear keyway symmetry of the present embodiment
Cubing, including mandrel 1, survey post 2 and dial gauge 3.Mandrel 1 is vertical multi-diameter shaft, includes bottom shaft part successively from the bottom to top
101st, flange 102, transition shaft part 103 and top shaft part 104, wherein in the positioning hole 901 on the inserted base 9 of bottom shaft part 101,
And it is overlapped on by the lower surface of flange 102 on the top surface of base 9, the external diameter of top shaft part 104 and the diameter of bore of gear 100
When, gear 100 from top to bottom inserts mandrel 1 by its centre bore along top shaft part 104, and by the upper surface of transition shaft part 103
The lower surface of gear 100 is supported.For symmetry of the keyway on the centre bore of prototype gear 100 with respect to its transverse tooth thickness, core
There is positioning key 4, the positioning key 4 is engaged with the keyway of gear 100, when gear 100 on the circumference of the top shaft part 104 of axle 1
When inserting top shaft part 104, positioning key 4 is also inserted into the keyway of gear, that is, gear 100 is circumferentially entered by positioning key 4
Row positioning.Survey post 2 and be positioned horizontally in the side of gear 100, and a teeth groove 5 is provided with close to one end of gear close to positioning key 4, survey post 2,
The teeth groove 5 can accommodate a tooth for being in same diameter on gear 100 with positioning key 4, that is to say, that survey the axis of post 2, teeth groove 5
Center line, the center line of positioning key 4 and the center of mandrel 1 are conllinear, and the tooth form of the profile of teeth groove 5 and gear 100 matches.Survey post
2 can swing around one end away from gear, when loading the gear of same specification difference error on mandrel 1, due to keyway and gear
The position disparity of transverse tooth thickness, the transverse tooth thickness for causing to insert in teeth groove 5 makes survey post produce different oscillating quantities, and is measured and swung by dial gauge
Measure to be calculated as the relative symmetry with transverse tooth thickness of gear keyway.
Specifically, first measuring a gear part as standard component, standardized element is placed on mandrel 1, adjusts percentage
Table after removing standard component, is put into other gears to zero on mandrel, then by and detected value be relative value, i.e., relative to standard
The value of part.The cubing is easy to operation, the operation of three coordinates is saved, suitable for mass detection.
Such scheme needs dial gauge directly to be measured to surveying post 2, due to surveying the fixation not easy to install of post 2, therefore, surveying
The one end of post 2 away from gear is connected with switch block 6, and the switch block 6 is rotated centered on locating dowel 7, with surveying post 2 on the switch block 6
Relative one end is connected with standard column 8, the axis collinear of the axis of the standard column 8, the center of locating dowel 7 with surveying post 2, by tooth
Post 2 is surveyed caused by wheel to swing centered on locating dowel 7, and standard column 8 is passed to by switch block 6, by the direct measurement mark of dial gauge 3
Oscillating quantity caused by quasi- post 8, post 2 is surveyed compared to direct measurement, the oscillating quantity of measurement standard post 8 is more prone to.
As the further improvement of above-mentioned technical proposal, the mandrel 1 is arranged on base 9, and the locating dowel 7 is arranged on
Can be on base along surveying post 2 in axial sliding on planker 10.Specifically, the both sides of planker 10 are corresponded on base 9 is respectively equipped with two
It is individual that the guide rail 11 playing the guiding role is slided to planker, and the center line using between two guide rails 11 is used as the mandrel positioning hole of base 9
901st, the centre of location of mandrel 1, survey post 2, locating dowel 7 and standard column 8.Press strip 12, the press strip are connected with the guide rail 11
It is pressed on the inside of 12 relative plankers on planker 10, the dial gauge 3 is installed on planker 10 and the jerk value of measurement standard post 8.It is logical
Planker 10 is crossed along axis of a cylinder moving to namely gear radial direction is surveyed, average pair of gear keyway on radical length can be measured
Title degree, measurement accuracy are higher.
As the further improvement of above-mentioned technical proposal, the survey post 2 and standard column 8 are inserted in the form of gap coordinates respectively
Enter in switch block 6, be easy to survey the dismounting of post 2 and standard column 8, change.
Due to mandrel positioning hole 901, mandrel 1, the center line positioning of post 2, locating dowel 7 and standard column 8 with two guide rails 11 is surveyed,
Installation positioning of the guide rail 11 on base 9 must precisely, and guide rail 11 is connected with base 9 by alignment pin 13, on guide rail and base 9
Use to match somebody with somebody for the hole that alignment pin 13 is installed and processed as mode, it is so-called to be exactly with work, base 9 and guide rail 11 are determined using clamp
Behind position on lathe the pin-and-hole of locating and machining pin 13 together, then insert in pin-and-hole by alignment pin 13, will can thus lead
Rail 11 is accurately positioned on base 9, and press strip 12 is linked together by the bolt 14 through guide rail 11 with base 9.
