The spline part is located at the inner end of the shaft body. The inner end of the spline part extends inwards to form a cylindrical fixing part, and the fixing part is provided with external threads matched with the round nut. The limiting part is sleeved on the outer side of the fixing part, the round nut is screwed on the fixing part, and the spline part and the round nut fix the limiting part. The utility model discloses can guarantee the normal operation of tractor with the more stable position of injecing in spline portion of differential side gear, improve the security performance of tractor greatly.
Description
Technical Field
The utility model relates to an axletree field, specific strenghthened type tractor drive semi-axis that says so.
Background
The drive half shaft is a shaft that transmits torque between the transmission case and the drive wheel, and a half shaft gear of the transmission case is engaged with a spline portion on the drive half shaft. The round piece is fixed at the inner end of the driving half shaft by two parallel bolts, so that the half shaft gear is limited at the position of the spline part, and the normal operation of the tractor is ensured. However, the acting force generated by the high-speed rotation of the side gear is large, so that the bolt is easy to break, and the circular sheet falls off from the driving half shaft, therefore, the side gear loses the limiting force and gradually leaves the position of the spline part, so that the tractor cannot normally run, and great potential safety hazards exist.
Disclosure of Invention
To above technical problem, the utility model discloses a strenghthened type tractor drive semi-axis, the utility model discloses use circular nut to fix spacing part on the fixed part, and then more stable with the position of differential side gear restriction at spline portion.
The utility model relates to a strenghthened type tractor drive semi-axis, including axis body, spline portion, round nut and spacing part. The spline part is located at the inner end of the shaft body. The inner end of the spline part extends inwards to form a cylindrical fixing part, and the fixing part is provided with external threads matched with the round nut. The limiting part is sleeved on the outer side of the fixing part, the round nut is screwed on the fixing part, and the spline part and the round nut fix the limiting part.
Preferably, the limiting component is a gear baffle.
Preferably, the gear baffle is an annular baffle.
Preferably, the inner side of the annular baffle is provided with an internal thread matched with the external thread.
Preferably, a stop washer is further arranged on the round nut.
The utility model has the advantages that: the utility model discloses can inject the position in spline portion more stable with half shaft gear, the normal operation of assurance tractor that can the at utmost. The internal screw thread sets up can make more firm the fixing on the fixed part of annular separation blade, further prevents that the annular separation blade from droing from the fixed part under half shaft gear's effect, has improved the security performance of tractor greatly.
Drawings
The invention will be further explained with reference to the accompanying drawings, which are simplified schematic drawings and are only schematic illustrations of the basic structure of the invention and do not constitute a limitation of the invention:
FIG. 1 is a schematic structural view of a reinforced tractor drive axle shaft of the present invention;
in the figure: 1. axis body, 2, spline portion, 3, fixed part, 31, external screw thread, 4, spacing part, 5, round nut.
Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure, as the terms used are used to describe particular embodiments only, and are not intended to limit the exemplary embodiments based on the disclosure.
Fig. 1 shows, the utility model relates to a strenghthened type tractor drive semi-axis, including axis body 1, spline portion 2, round nut 5 and spacing part 4. The spline part 2 is located at the inner end of the shaft body 1. The inner end of the spline part 2 extends inwards to form a cylindrical fixing part 3, and the fixing part 3 is provided with an external thread 31 matched with the round nut 5. Limiting component 4 cover is in the fixed part 3 outside, will round nut 5 is twisted on fixed part 3, spline portion 2 with round nut 5 will limiting component 4 is fixed, still be equipped with lock washer (not shown in the figure) on the round nut 5, can be more firm fix limiting component 4 on fixed part 3. The limiting component 4 is a gear baffle. The gear flap is preferably an annular flap. The inner side of the annular separation blade can be further provided with an internal thread matched with the external thread 31, the annular separation blade is screwed on the fixing part 3, and then the circular nut 5 is screwed to further fix the annular separation blade, so that the annular separation blade is more firmly fixed on the fixing part 3.
Round nut 5 more firmly fixes stop part 4 on fixed part 3, consequently when spline portion 2 and side gear engaged with each other and rotate, stop part 4 with the more stable position of injecing in spline portion 2 of side gear, make tractor can normal operating. The provision of the stop washer enhances the locking force of the round nut 5. The annular separation blade inboard sets up the internal thread, can make more firm the fixing on fixed part 3 of annular separation blade, further prevents that the annular separation blade from droing from fixed part 3 under half shaft gear's effect, has improved the security performance of tractor greatly.
In the description of the present invention, the term "inner end" means an end axially close to the center of the vehicle body; the terms "outside" and "inside" describe the orientation with reference to the central axis of the shaft body 1, and are "inside" near the central axis and "outside" away from the central axis. The above terms are only for the purpose of simplifying the description of the present invention, and should not be construed as limiting the present invention.
In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
