Detailed Description
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
A tapered roller has a tapered surface with a constant convexity. In order to realize the detection of the taper, the following taper measuring device is adopted:
as shown in fig. 1, the taper measuring device includes a V-shaped base 1, an end face positioning block 5, and two sets of gauge stands 6. The V-shaped base 1 is a block-shaped body, in order to stabilize the tapered roller 3, the V-shaped surface of the V-shaped base 1 is arranged upwards, and the included angle of the V-shaped surface is 90 degrees. Since the tapered surface of the tapered roller 3 has convexity, it is not possible to directly position it radially using the V-profile. In order to realize the radial positioning of the tapered roller 3, two parallel positioning support rods 2 are respectively embedded on the V-shaped surface of the V-shaped base 1, and the positioning support rods 2 are used for the radial positioning of the tapered roller 3 and enabling the conical surface of the tapered roller 3 to be separated from the contact with the V-shaped surface. In order to improve the wear resistance of the positioning support rod 2, the positioning support rod 2 is made of hard alloy. The end face positioning block 5 is connected to one side face of the V-shaped base 1, and the end face positioning block 5 is in contact with one end face of the tapered roller 3 and used for positioning the end face of the tapered roller 3. In order to improve the positioning accuracy, a steel ball (not shown in the figure) is embedded in a contact part of the end face positioning block 5 and the end face of the tapered roller 3, and the end face positioning block 5 is in contact with the end face of the tapered roller 3 through the steel ball. Up to this point, the tapered roller 3 has been restricted in the remaining degrees of freedom, in addition to the degree of freedom of rotation in the axial direction.
Two sets of meter racks 6 are attached to the top surface of the V-shaped base 1, which is parallel to one of the V-profiles. One end of each group of gauge stand 6 is fixed with a dial indicator 4 through a gauge stand screw 8, and a measuring rod of the dial indicator 4 is in contact with the conical surface of the tapered roller 3 and is used for measuring the conical degree of the conical surface of the tapered roller 3 at different positions. In order to realize the measurement of the tapered rollers 3 of various models, a connecting groove is arranged on the gauge stand 6, the gauge stand 6 is connected with the V-shaped base 1 through a screw 7 and the connecting groove, and the connecting groove is used for adjusting the measuring position of the dial indicator 4, so that the measuring rod of the dial indicator 4 is always arranged along the radial direction of the tapered rollers 3. Similarly, an adjusting groove is arranged on the end face positioning block 5, the end face positioning block 5 is connected with the V-shaped base 1 through a screw 7 and the adjusting groove, and the adjusting groove is used for adjusting the positioning position of the end face positioning block 5, so that the steel ball always abuts against the appropriate position on the end face of the tapered roller 3.
During measurement, the conical surface of the tapered roller 3 is placed on the V-shaped surface, the four positioning support rods 2 are respectively contacted with the left end and the right end of the conical surface of the tapered roller 3, the tapered roller 3 is pushed to enable one end face of the tapered roller to be contacted with the steel ball on the end face positioning block 5, then the tapered roller 3 is rotated, and the conicity of the conical surface of the tapered roller 3 at different positions is measured. Before measurement, the taper of one standard tapered roller 3 is measured, the indexes of the two dial indicators 4 are used as standard values, then the tapered roller 3 to be measured is placed on the standard tapered roller for measurement, the indexes of the two dial indicators 4 are observed and recorded, and whether the indexes are within an allowed tolerance range is judged to judge whether the tapered roller is qualified.
