Abstract
The utility model discloses a centering structure of transmission shaft and flange equipment, it includes involute spline, transmission shaft, flange, characterized by: an involute spline groove is formed in the inner hole of the flange, and the involute spline main tooth is in transmission fit with the involute spline groove in the inner hole of the flange; the outer sides of two ends of the involute spline shaft are respectively provided with a small section of shaft diameter, and the shaft diameters of the two ends are in clearance fit with the outer sides of two ends of the involute spline groove in the flange; the advantages are that: the spline centering device is stable and reliable in structure centering mode, improves the centering precision of the spline, reduces the variation of the swing difference of the end face of the flange and the radial position, reduces the rework caused by the unstable matching of the spline and the flange, is simple to operate, and improves the production efficiency.
Description
The technical field is as follows:
the utility model belongs to the technical field of the engineering component, a centering structure of transmission shaft and flange equipment is related to.
Background art:
in the automobile processing and manufacturing process, when a transmission shaft is connected with a flange, an involute spline must be installed in the flange, the involute spline is usually matched and positioned with the inner diameter gear side of the flange, so that the requirements of restraint, torque transmission, centering and the like are met, but the assembly is complicated in the installation process, repeated attempts are needed, the centering of the axis is inaccurate after the involute spline is installed, and the variation of the pendulum difference between the end face of the flange and the radial direction is large when a part runs after the flange is connected with the transmission shaft; because the processing precision of parts is difficult to optimize, the conditions of size constraint, incapability of shortening the length of the spline, unobvious improvement effect of the size of the lengthened limited spline and the like exist in the product installation, a centering structure of the spline is required to be designed to meet the requirement of spline centering, and further the variation of the end face and the radial run-out of the flange is reduced.
Disclosure of Invention
The utility model aims at providing a centering structure of transmission shaft and flange equipment, its structure centering mode is reliable and stable, improves spline centering precision to reduce flange terminal surface and radial two pendulum difference changes, reduce the rework that arouses because of spline and flange cooperation are unstable simultaneously, easy operation improves production efficiency.
In order to achieve the above purpose, the utility model provides a technical scheme is: it includes involute spline, transmission shaft, flange, characterized by: an involute spline groove is formed in the inner hole of the flange, and the involute spline main tooth is in transmission fit with the involute spline groove in the inner hole of the flange; the outer sides of the two ends of the involute spline shaft are respectively provided with a small section of shaft diameter, and the shaft diameters of the two ends are in clearance fit with the outer sides of the two ends of the involute spline groove in the flange.
The utility model has the effects that: the spline centering device is stable and reliable in structure centering mode, improves the centering precision of the spline, reduces the variation of the swing difference of the end face of the flange and the radial position, reduces the rework caused by the unstable matching of the spline and the flange, is simple to operate, and improves the production efficiency.

In the figure: 1. an involute spline; 2. the diameter of the shaft; 3. a spline shaft; 4. a flange; 5. a drive shaft.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, an inner hole of the flange 4 is provided with an involute spline groove, and a main tooth of the involute spline 1 is in transmission fit with the involute spline groove of the inner hole of the flange 4; the outer sides of two ends of the shaft of the involute spline 1 are respectively provided with a small section of shaft diameter 2, and the shaft diameters 2 of the two ends are in clearance fit with the outer sides of two ends of the involute spline groove in the flange 4.
Under the guiding action of the shaft diameters 2 at the two ends, the involute spline 1 is inserted into the flange 4, and the main teeth of the involute spline 1 are matched with and drive the internal spline groove of the flange 4; at the moment, the shaft diameters 2 at two ends of the involute spline 1 are in clearance fit with the outer sides of two ends of an involute spline groove in the flange 4, and then the end face of the flange 4 is connected with the transmission shaft 5 to finish component installation; when the involute spline 1 works, the main teeth of the involute spline 1 drive the flange 4 to rotate, the flange 4 drives the transmission shaft 5 to rotate, the shaft diameters 2 at two ends play a role in improving the centering precision and the centering stability of the axis of the spline, the variation of the pendulum difference between the end surface of the flange 2 and the radial position is reduced, the rework caused by the unstable matching of the spline 1 and the flange 4 is reduced, the operation is simple, and the production efficiency is improved.
The exemplary embodiments of the present invention are not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.
