Problems solved by technology

After excessive wear, iron filings will be generated, and the iron filings will fall on the rolling surface through the gap of the rolling head. These falling iron filings will directly cause defects on the processed surface under the action of the rolling force, and eventually waste products will appear.

Embodiment Construction

[0010] From figure 1 It can be seen from the figure that a rolling head includes a guide wheel 2, a needle bearing 3, a mandrel 4, a roller 7, an end cover 6 and a housing 1, the mandrel 4 is matched with the housing 2, and passes through the end cover 6 seal. The above-mentioned compositional structure and connection relationship of each component are the same as those of the prior art, and will not be repeated here.

[0011] The feature of the present invention is that: the mandrel 4 is also equipped with a planar bearing 5 , and the planar bearing 5 is installed between the guide wheel 2 , the end cover 6 and the housing 1 . Specifically, the plane bearings 5 ​​are located on both sides of the guide wheel 2, the left side is fixed between the guide wheel 2 and the housing 1, and the right side is fixed between the guide wheel 2 and the end cover 6. In this way, a plane shaft, 5 is added between the housing 1, the end cover 6 and the guide wheel 2, as a transition between ...

Abstract

The invention relates to a rolling head. The rolling head comprises a guide wheel, a rolling needle bearing, a mandrel, rolling wheels, an end cover and a shell, wherein plane bearings are further installed on the mandrel; and the plane bearings are located at the two sides of the guide wheel and fixed through the shell or the end cover. The rolling head disclosed by the invention is simple and reasonable in structure, low in cost and long in service life. Excessive wear among the guide wheel, the shell and the end cover due to the action of different axial rolling component forces on the two rolling wheels is avoided. Thus the problem of declining of the surface quality of a rolled crankshaft caused by that the iron chips generated due to excessive wear between the rolling wheels and the shell fall into a rolling groove along a gap can be avoided.

Description

technical field [0001] The invention relates to rolling equipment, in particular to a rolling head. Background technique [0002] We know that the rolling head is used in the crankshaft machining process. At present, the rolling head is generally composed of a guide wheel, a needle bearing, a mandrel, a roller, an end cover and a housing. Because there is a pressure difference in the rolling force that the two rollers are subjected to, the component force along the direction of the mandrel cannot be balanced. The guide wheel moves axially under the action of axial force, and rubs against the shell and end cover. After excessive wear, iron filings will be produced, and the iron filings will fall on the rolling surface through the gap of the rolling head. These falling iron filings will directly cause defects on the processed surface under the action of rolling pressure, and eventually waste products will appear. Contents of the invention [0003] The technical problem to...
