Invention also provides a kind of rotating shaft, rotating shaft has axle mold joint, and platform has been cut in rotating shaft, and this platform is crossing with axle mold joint.
The diameter in this rotating shaft stage casing is less than the diameter of outer end and forms axle journal, and the outer end of axle journal is termination, and axle journal is provided with annular groove.
Below advantage of the present invention or principle are described:
1, because rotating shaft is provided with axle mold joint, carry out adding man-hour at countershaft, burr being left at axle mold joint place, impacting for avoiding the cooperation of the burr at this place to axis hole, platform has been cut in rotating shaft, because this platform is crossing with mold joint, the burr on mold joint is positioned at this platform place, thus avoids burr to match with the inwall turning hole, improve the quality of fit of axis hole, reduce the noise between axis hole, make shaft hole matching more stable, quality of product is higher;
2, in the course of working turning hole, the mold joint place, hole turning hole also can form burr, and the cooperation of axis hole is impacted, and after in rotating shaft, annular groove is set, the burr turned on hole can be relative with the position of annular groove, avoid the burr turned on hole to contact with rotating shaft, further increase the quality of fit of axis hole;
3 and mold joint is positioned on the medial axis of platform, now, mold joint (i.e. the position of burr) with turn the distance of hole inwall farthest;
4, because the axle journal position of rotating shaft plays a key effect for the cooperation between axis hole, so platform and annular groove are located at axle journal position, the quality of fit between axis hole can better be improved.

Embodiment
Below embodiments of the invention are described in detail.
As shown in Figure 1 to Figure 3, a kind of shaft hole matching mechanism, comprise the rotating shaft 1 that matches and turn hole 2, rotating shaft 1 has axle mold joint 3, and rotating shaft 1 has been cut platform 4, and this platform 4 is crossing with axle mold joint 3.
Wherein, described in turn hole 2 middle part internal diameter be less than the internal diameter of its outer end and form pore-throat 7, be limit dais 8 outside pore-throat 7; The diameter in rotating shaft 1 stage casing is less than the diameter of outer end and forms axle journal 9, and the outer end of axle journal 9 is termination 10, and limited of the termination 10 of rotating shaft 18 is spacing, and the axle journal 9 of rotating shaft 1 matches with the pore-throat 7 turning hole 2.
The described hole 2 that turns has hole mold joint 6, and the axle journal 9 of described rotating shaft 1 is provided with annular groove 5, and this annular groove 5 is relative with hole mold joint 6.Described platform 4 is two, be located at two opposite sides of the axle journal 9 of rotating shaft 1 respectively, and described mold joint is positioned on the medial axis of platform 4.
The termination 10 of described rotating shaft 1 is provided with elasticity slot to make way 11, and this elasticity slot to make way 11 extends to axle journal 9 place, and two described platforms 4 lay respectively at the both sides of this elasticity slot to make way 11, and parallel with this elasticity slot to make way 11.
The present embodiment tool has the following advantages:
1, because rotating shaft 1 is provided with axle mold joint 3, carry out adding man-hour at countershaft 1, burr being left at axle mold joint 3 place, impacting for avoiding the cooperation of the burr at this place to axis hole, rotating shaft 1 has been cut platform 4, because this platform 4 is crossing with mold joint, the burr on mold joint is positioned at this platform 4 place, thus avoids burr to match with the inwall turning hole 2, improve the quality of fit of axis hole, reduce the noise between axis hole, make shaft hole matching more stable, quality of product is higher;
