Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
Embodiment 1
The output shaft of gear of the present embodiment, as shown in Figure 1 to Figure 3, its end axis is to evenly offering four grooves 1, and form a protuberance 2, four protuberance 2 entirety between two adjacent grooves 1 and form cruciform, the width of each protuberance 2 is a; Bottom land 3 arc-shaped in evagination of each groove 1, and, the bottom land 3 of four grooves 1 be positioned at diameter be R circumferentially.
For measuring the measurer of said gear force-output shaft hip cross size, as shown in Fig. 4 to Fig. 8, comprise pedestal 5, one end of pedestal 5 is provided with drift 4 and the other end is provided with no-go gage 6, drift 4 offers the first circular port 10, is evenly provided with four groove A11 along the circumferential outer of the first circular port 10, and these four groove A11 entirety are in cross distribution, the groove width a1 of each groove A11 equals the upper limit of a, and the diameter R1 of the first circular port 10 equals the upper limit of R.
No-go gage 6 offers the second circular port 16, four groove B14 are evenly provided with along the circumferential outer of the second circular port 16, these four groove B14 entirety are in cross distribution, and the groove width a2 of each groove B14 equals the lower limit of a, and the diameter R2 of the second circular port 16 equals the lower limit of R.
For the ease of protuberance 2 through groove A11 and groove B14, the both sides of the bottom land of each groove A11, groove B14 offer the groove C1515 that cross section is circular arc respectively.
First circular port 10 of the present embodiment and the second circular port 16 are all the counterbore do not penetrated, drift 4 is right cylinder, and the first circular port 10 is opened in the center of drift 4, and no-go gage 6 is also right cylinder, second circular port 16 is opened in the center of no-go gage 6, and pedestal 5 is solid right cylinder simultaneously.In order to make the external form of whole measurer be unified, drift 4, no-go gage 6 and pedestal 5 are all the right cylinder that diameter is identical, and three is coaxially arranged.Drift 4 and no-go gage 6 are threaded with pedestal 5 respectively, be specially: the two ends of pedestal 5 are respectively equipped with joint pin 7, the end of joint pin 7 is provided with external thread 8, accordingly, the end face that drift 4, no-go gage 6 are connected with pedestal 5 offers the internal thread hole 9 matched with external thread 8 respectively.
In order to increase the working strength of drift 4 and no-go gage 6, be equipped with the body A12 of ring-type outside drift 4, the bottom land of groove A11 equals the thickness of body A12 to the distance of drift 4 periphery; Be equipped with the body B17 of ring-type outside no-go gage 6, the bottom land of groove B14 equals the thickness of body B17 to the distance of no-go gage 6 periphery.
Use the measurer of the present embodiment come detection of gear force-output shaft whether qualified time, respectively the protuberance 2 in cross distribution of output shaft of gear end to be detected is inserted in the groove A11 of the drift 4 or groove B14 of no-go gage 6; If drift 4 by; part is qualified, by then this part is defective; . when detecting with no-go gage 6, if by; part would be defective, if not by, then part is qualified.
Embodiment 2
The measurer difference from Example 1 of the present embodiment is: pedestal 5 is the right cylinder of hollow and coaxially arranges with drift 4, no-go gage 6 respectively, first circular port 10 is communicated with the second circular port 16 by pedestal 5, groove A11 to be communicated with groove B14 by pedestal 5 and with groove B14 one_to_one corresponding, namely the internal diameter of the accommodating cavity of pedestal 5 is much larger than the external diameter of output shaft of gear, and namely the accommodating cavity of pedestal 5 can not stop output shaft of gear moving ahead therein.
