The specific meaning of the above terms in the present utility model can be understood by those skilled in the art according to the specific circumstances.
Example 1:
a large end face runout detection tool for tapered rollers is shown in fig. 3, and mainly comprises a seat body 1, three cylinders 2 and a dial indicator 4, and the structure and the function of the tool are specifically described below.
Referring to fig. 1, the base 1 includes a lower base 11 and an upper base 12, three support columns 13 are disposed between the lower base 11 and the upper base 12, and nuts are screwed to the upper ends of the support columns 13 to connect the upper base 12 and the upper base 12 together. Three pairs of inclined round holes are arranged on the lower seat body 11 and the upper seat body 12.
Referring to fig. 2, stepped shafts are provided at both ends of the cylinder 2, and an annular groove is provided at the middle part of the cylindrical surface.
Referring to fig. 3, three cylinders 2 are obliquely installed between the lower housing 11 and the upper housing 12. In this embodiment, three cylinders 2, the stepped shafts at both ends of which can rotate in the circular holes, are coaxially connected with a handle 3 at the upper end of one of the cylinders 2.
Referring to fig. 4, after the tapered roller 5 is put in, the cylindrical surfaces of the three cylinders 2 are in linear tangential contact with the tapered surfaces of the tapered roller 5, and it is apparent that the contact line is a generatrix of both the cylindrical surfaces and the tapered roller 5. At this time, the tapered roller 5 has only a degree of freedom of rotation in the axial direction thereof, and the remaining degrees of freedom are limited by the three cylinders 2.
Referring to fig. 1 and 3, a gauge stand column 14 is fixed to one side of the lower base 11, a gauge stand clamping rod 15 is horizontally hinged to the upper end of the gauge stand column 14, a dial gauge 4 is clamped on the gauge stand clamping rod 15, and the dial gauge 4 is used for detecting runout of the large end face of the tapered roller. Thus, when the tapered roller 5 is taken and placed into the base, the holder holding rod 15 can be rotated outward to one side, so that the space for taking and placing the tapered roller 5 can be opened. During detection, the gauge stand clamping rod 15 can be rotated to the inner side, so that the measuring head of the dial gauge 4 is pressed against the large end face of the tapered roller 5.
During detection, the dial indicator 4 is rotated to the position above the large end face of the tapered roller 5, then the handle 3 drives the cylinders 2 to rotate, the cylinders 2 can be regarded as driving rollers, the other two cylinders 2 can be regarded as driven rollers, the driving rollers and the driven rollers drive the tapered roller 5 to start rotating through friction, and at the moment, the dial indicator 4 can detect runout of the large end face of the tapered roller 5.
The cylindrical surfaces of the three cylinders are in linear tangent contact with the conical surface of the tapered roller, so that the tapered roller can rotate around the axis of the tapered roller on the premise of ensuring the rotation precision of the tapered roller. Compared with the complete fitting of the tapered sleeve and the tapered roller in the background art, the detection tool solves the problem that the tapered roller is difficult to rotate, and is convenient to take out the tapered roller.
Example 2:
in example 1, three cylinders 2 are rotatable, and there is a fit gap that affects the accuracy of the measurement to some extent.
Referring to fig. 4, in the present embodiment, one cylinder 2 among three cylinders 2, stepped shafts at both ends thereof are rotatable in circular holes, and a handle 3 is coaxially connected to the upper end of the cylinder 2. The stepped shafts at the two ends of the other two cylinders 2 are tightly matched with the corresponding round holes and cannot rotate.
Advantageously, no fit clearance exists without rotation, thus improving the accuracy of the measurement to some extent. Disadvantageously, the rolling friction becomes sliding friction, increasing the resistance of the tapered roller to spin.
The parts not described in detail are prior art. Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the utility model as defined by the appended claims and their equivalents.
