Abstract
The utility model discloses a clutch transmission shaft structure which comprises a hollow shaft body, wherein an inner spline hole is formed in one end of the hollow shaft body, a coaxial positioning hole which is connected with the end part of the inner spline hole and has a diameter larger than that of the inner spline hole is further formed in the hollow shaft body, and a positioning shaft sleeve which is used for being matched with an engine output shaft is fixedly arranged in the coaxial positioning hole. According to the clutch transmission shaft structure, the coaxial positioning holes with the diameters larger than those of the inner spline holes are formed in the shaft body, so that the inner spline holes at the end parts of the hollow shaft body can be machined and formed in a broaching process by a broaching tool, and after the inner spline holes are machined, the positioning shaft sleeve is pressed into the coaxial positioning holes in the hollow shaft body. The clutch transmission shaft structure enables the inner spline hole at the end part of the hollow shaft body to be formed without an extrusion process, reduces the forming difficulty of the inner spline hole, and is beneficial to reducing the manufacturing cost of the inner spline hole.
Description
Technical Field
The utility model relates to the technical field of mechanical parts, in particular to a transmission shaft.
Background
The clutch transmission shaft shown in the attached figure 1 of the specification is a hollow shaft, one end of the clutch transmission shaft is provided with a spline hole 1 matched with an external spline on a power output shaft of an engine and a positioning shaft hole 2 matched with the power output shaft of the engine, and the power of the engine is transmitted to the clutch transmission shaft through the spline. In the clutch transmission shaft with the structural form, the diameter of the positioning shaft hole 2 is smaller than the inner diameter of the spline hole 1, so that the spline hole 1 cannot be machined on a broaching machine by adopting a broaching process; in the prior art, the spline hole 1 is manufactured and molded by adopting an extrusion process, so that the process difficulty is high and the manufacturing cost is high.
Disclosure of Invention
In view of the above, the utility model aims to provide a clutch transmission shaft structure, so as to solve the technical problems of high process difficulty and high manufacturing cost caused by the fact that an inner hole of a spline of the existing transmission shaft is required to be molded by adopting an extrusion process.
The clutch transmission shaft structure comprises a hollow shaft body, wherein an inner spline hole is formed in one end of the hollow shaft body, a coaxial positioning hole which is connected with the end part of the inner spline hole and has a diameter larger than that of the inner spline hole is further formed in the hollow shaft body, and a positioning shaft sleeve which is used for being matched with an engine output shaft is fixedly arranged in the coaxial positioning hole.
Further, the positioning shaft sleeve is in interference fit with the coaxial positioning hole.
The utility model has the beneficial effects that:
according to the clutch transmission shaft structure, the coaxial positioning holes with the diameters larger than those of the inner spline holes are formed in the shaft body, so that the inner spline holes at the end parts of the hollow shaft body can be machined and formed in a broaching process by a broaching tool, and after the inner spline holes are machined, the positioning shaft sleeve is pressed into the coaxial positioning holes in the hollow shaft body. The clutch transmission shaft structure enables the inner spline hole at the end part of the hollow shaft body to be formed without an extrusion process, reduces the forming difficulty of the inner spline hole, and is beneficial to reducing the manufacturing cost of the inner spline hole.

Detailed Description
The utility model is further described below with reference to the drawings and examples.
As shown in fig. 2 and 3, the clutch transmission shaft structure in this embodiment includes a hollow shaft body 1, one end of the hollow shaft body is provided with an inner spline hole 2, a coaxial positioning hole 3 connected with an end of the inner spline hole and having a diameter larger than that of the inner spline hole is further provided in the hollow shaft body, and a positioning shaft sleeve 4 for being matched with an engine output shaft is fixedly provided in the coaxial positioning hole. In this embodiment, the locating shaft sleeve is in interference fit with the coaxial locating hole, and the locating shaft sleeve 4 is pressed in the coaxial locating hole 3 through a press, so that the installation is convenient, and the fixing is reliable.
In the clutch transmission shaft structure in the embodiment, the coaxial positioning hole with the diameter larger than that of the inner spline hole is formed in the shaft body, so that the inner spline hole at the end part of the hollow shaft body can be machined and formed in a broaching process by a broaching tool, and after the inner spline hole is machined, the positioning shaft sleeve is pressed into the coaxial positioning hole in the hollow shaft body. The clutch transmission shaft structure enables the inner spline hole at the end part of the hollow shaft body to be formed without an extrusion process, reduces the forming difficulty of the inner spline hole, and is beneficial to reducing the manufacturing cost of the inner spline hole.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present utility model, which is intended to be covered by the scope of the claims of the present utility model.
