The main surface of the star wheel is the inner hole and the outer circle. The main technical requirements of the star wheel are as follows:

1, inner hole

The inner hole is the most important surface for supporting or guiding. It is usually matched with the moving shaft, cutter or piston. The inner hole diameter size accuracy is generally 2 levels, precision bushings sometimes take 1 level. The inner hole shape accuracy, generally should be controlled within the aperture tolerance, some precision bushing control in the aperture tolerance 11~23, even more stringent. For long sleeves, in addition to cylindricity and coaxiality, attention should be paid to the straightness of the borehole axis. In order to ensure the function of parts and improve its wear resistance, the inner surface roughness is generally 3.2~0.2aaRR, and some are up to 0.05aR or more.

2, the outer circle

The surface of the outer circle is generally the bearing surface of the sleeve part and is often connected to the hole in the box or rack casserole by static fit or transition fit. The dimensional accuracy of the outer diameter is usually 2 to 3 levels; the shape accuracy is controlled within the outer diameter tolerance; the roughness is generally 6.3~0.8aaRR.

1) Concentricity between inner and outer circles

When the inner diameter of the final processing system is carried out after the sleeve is loaded into the base, the concentricity between the inner and outer rings of the sleeve is required to be low; if the final processing is required before completion of the assembly, it is generally 0.01 to 0.05 mm.

2) Verticality of hole axis and end face

The end face of the star wheel (including the flange end face) is subjected to axial load during operation, or is not used as a bearing but is used as a positioning surface in machining. The perpendicularity to the hole axis is required to be relatively high, generally 0.02 to 0.05 mm.
