Abstract
The invention discloses a clamp for shaving of a driving gear. The clamp for the shaving of the driving gear comprises a stepped central shaft and a cylindrical ejector sleeve, wherein the stepped central shaft comprises a large-diameter shaft section and a small-diameter shaft section. The cylindrical ejector sleeve is arranged on the small-diameter shaft section in a sleeving mode. A gear to be machined is arranged on the large-diameter shaft section in a sleeving mode. One end of the ejector sleeve is provided with a locating circular truncated cone extending in the radial direction. The size of the outer circle of the locating circular truncated cone is larger than that of the inner ring of the gear to be machined. According to the clamp for shaving of the driving gear, the size of the outer circle of the locating circular truncated cone is larger than that of the inner ring of the gear to be machined, it is avoided that the gear to be machined moves axially in the shaving process, and the shaving precision and the product quality are improved.

For ensureing the positioning precision of gear, gear is avoided to produce circular runout in Shaving Process, affect the crudy of product, Chinese invention patent CN202169422U provides a kind of gear shaving clamp, comprise the step mandrel being provided with large footpath shaft part and path shaft part, the cylindrical shape top cover being enclosed within the cylindrical shape ringfeder on the shaft part of described large footpath and being enclosed within described path shaft part, wherein, described large footpath shaft part is provided with the radial spacing round platform that extends and a conical section away from one end of the shaft shoulder, described conical section is between spacing round platform and large footpath shaft part, the bigger diameter end of conical section is near spacing round platform, the aperture, two ends of described ringfeder is conical bore, described conical section withstands in the conical bore of ringfeder one end, the other end of ringfeder axially extends the shaft shoulder, one end of described top cover is provided with the radial conical boss extended, this conical boss withstands in the conical bore of the elongated end of ringfeder, and the other end of top cover axially extends the end face of path shaft part.This invention removes the centering error between gear and step mandrel, avoid gear because of the circular runout that centering error produces in Shaving Process, raising shaving precision and product quality.But can be found out by the Figure of description of this invention, the excircle dimension of the conical boss of top cover and the inner circle size of gear very nearly the same, in Shaving Process, after strength of gear, easily there is axial float, affect shaving precision and product quality.
Summary of the invention
The object of the invention is to provide one and avoids gear to be processed to produce axial float in Shaving Process, improves the driving gear Fixture for Gear-shaving of shaving precision and product quality.
For achieving the above object, the technical solution used in the present invention is: a kind of driving gear Fixture for Gear-shaving, comprise the step mandrel being provided with large footpath shaft part and path shaft part, the cylindrical shape top cover be enclosed within path shaft part, geared sleeve to be processed is located on the shaft part of described large footpath, one end of described top cover is provided with the radial positioning round table extended, the excircle dimension of this positioning round table is greater than the inner circle size of described gear to be processed, avoid gear to be processed to produce axial float in Shaving Process, improve shaving precision and product quality.
Preferably, the excircle dimension of described positioning round table is greater than the inner circle size 20 ~ 30mm of described gear to be processed, i.e. the large 10 ~ 15mm of single side size.
In technique scheme, described large footpath shaft part is provided with spacing round platform away from one end of the shaft shoulder, and the excircle dimension of described positioning round table compares the little 0 ~ 10mm of excircle dimension of described spacing round platform, i.e. the little 0 ~ 5mm of single side size.
Preferably, the excircle dimension of described positioning round table is equal with the excircle dimension of described spacing round platform.
In technique scheme, the side relative with described large footpath shaft part of described spacing round platform is reducing shaft part, and the large footpath section of this reducing shaft part, near described spacing round platform, avoids stress concentrate and shorten the service life of sun gear Fixture for Gear-shaving.
In technique scheme, the outer rim rounding of described large footpath section.
In technique scheme, the two ends of described step mandrel are provided with the centre bore adopting and be with the Type B centre drill protecting cone to process.
Further technical scheme, described top cover and path shaft part matched in clearance.
In technique scheme, the other end of described top cover axially extends the end face 30 ~ 45mm of described path shaft part, and this end of described top cover is provided with the top suitable conical aperture with lathe, being convenient to the top taper seat of lathe withstands in the pyramid type aperture of top cover extension end face, axial compression gear to be processed.
Because technique scheme is used, the advantage that the present invention compared with prior art has is:
1. the excircle dimension of positioning round table of the present invention is greater than the inner circle size of gear to be processed, avoids gear to be processed to produce axial float in Shaving Process, improves shaving precision and product quality.
