| 摘 要： | As a final process in roller bearing manufacturing, Through Centerless Superfinishing is of great importance to the performance of bearings. Applied loads, rotational speeds, reciprocating frequencies and amplitude of superfinishing stones are crucial parameters, which mainly influence the surface topography, and are difficult to be adjusted to achieve optimal superfinishing effect, so product quality is unstable in practice. A superfinishing model is firstly established, which includes cutting and motion models. And then a simulation method is presented to form the topography on the condition of various combinations of the above three parameters, the effect of every parameter on the topography being clarified. This work provides a useful means to select reasonable combination of superfinishing parameters for roller bearing buildings.

| Abstract: | As a final process in roller bearing manufacturing, Through Centerless Superfinishing is of great importance to the performance of bearings. Applied loads, rotational speeds, reciprocating frequencies and amplitude of superfinishing stones are crucial parameters, which mainly influence the surface topography, and are difficult to be adjusted to achieve optimal superfinishing effect, so product quality is unstable in practice. A superfinishing model is firstly established, which includes cutting and motion models. And then a simulation method is presented to form the topography on the condition of various combinations of the above three parameters, the effect of every parameter on the topography being clarified. This work provides a useful means to select reasonable combination of superfinishing parameters for roller bearing buildings. |
