It can guarantee the correct assembly of drive shaft, improves assembly efficiency.
Description
Technical Field
The utility model relates to the technical field of driving shaft assembly, in particular to an anti-rotation tool for driving shaft assembly.
Background
The assembly accuracy of the drive shaft, which is one of the main components of the vehicle transmission system, will directly affect whether the transmission system can work properly.
Referring to fig. 1, the conventional method for assembling the drive shaft generally includes: the drive shaft 4 is directly fitted into the left side gear 22 of the differential assembly 2, i.e., the spline teeth of the second external splines 41 of the drive shaft 4 are aligned with the spline grooves of the second internal splines 221 of the left side gear 22 in the differential assembly 2, and then the drive shaft can be correctly fitted. This process requires continuous rotation of the drive shaft 4 to adjust the positional relationship between the spline teeth of the second male spline 41 and the spline grooves of the second female spline 221. When the rotating drive shaft 4 is aligned with the second external splines 41 and the second internal splines 221, the left side gear 22 is ideally not rotated, but under the condition of no clamping tool, the left side gear 22 is easily rotated, so that a certain failure rate exists in the installation of the drive shaft 4 into the differential assembly 2, which causes the production line to be suspended or the drive shaft 4 to be assembled in place, thereby affecting the production efficiency and increasing the production cost.
Disclosure of Invention
The utility model aims to provide an anti-rotation tool for assembling a driving shaft, which can ensure the correct assembly of the driving shaft and improve the assembly efficiency.
The anti-rotation tool for assembling the driving shaft comprises a rod body, wherein a first external spline which is correspondingly matched with a first internal spline of a right half shaft gear in a differential assembly is arranged at the end part of the rod body, an anti-rotation pin radially penetrates through the rod body, and the end part of the anti-rotation pin is abutted against a transmission shell.
Furthermore, a position of the rod body close to the first external spline is annularly provided with a limiting boss.
Compared with the prior art, the utility model has the following beneficial effects.
1. According to the utility model, the end part of the rod body is provided with the first external spline which is correspondingly matched with the first internal spline of the right half shaft gear in the differential assembly, the first external spline at the end part of the rod body is aligned and inserted into the first internal spline of the right half shaft gear during assembly, then the rod body is rotated to enable the end part of the anti-rotation pin to be abutted against the transmission shell, so that the rotation of the right half shaft gear is limited, the rotation of the planetary gear which is meshed with the right half shaft gear in the differential shell is correspondingly limited, the rotation of the left half shaft gear is further limited, the assembly of the driving shaft and the left half shaft gear is more convenient, and the assembly efficiency is improved on the premise of ensuring the correct assembly of the driving shaft.
2. The utility model has simple structure and convenient and quick operation, ensures that the first external spline is correctly matched with the first internal spline of the right half-shaft gear by annularly arranging the limiting boss at the position of the rod body close to the first external spline, and avoids the damage of the right half-shaft gear caused by overlarge insertion amount of the rod body.

FIG. 3 is one of the schematic cross-sectional views of the tool of the present invention;
fig. 4 is a second schematic cross-sectional view of the tool of the present invention.
In the figure, 1-rod body, 11-first external spline, 12-limit boss, 2-differential assembly, 21-right axle shaft gear, 211-first internal spline, 22-left axle shaft gear, 221-second internal spline, 23-planetary gear, 3-anti-rotation pin, 4-driving shaft, 41-second external spline and 5-transmission shell.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 2 to 3, the anti-rotation tool for assembling the driving shaft includes a rod body 1, a first external spline 11 correspondingly matched with a first internal spline 211 of a right half shaft gear 21 in a differential assembly 2 is arranged at an end portion of the rod body 1, an anti-rotation pin 3 radially penetrates through the rod body 1, and an end portion of the anti-rotation pin 3 abuts against a transmission housing 5.
The position ring that the body of rod 1 is close to first external spline 11 is equipped with spacing boss 12, the setting up of spacing boss 12 has guaranteed that first external spline 11 and right side shaft gear 21's first internal spline 211 correctly matches, has avoided the body of rod 1 insertion volume too big to lead to right side shaft gear 21 to damage.
During the concrete assembly, align the first external spline 11 of the body of rod 1 tip and insert right side shaft gear 21's first internal spline 211 in, then rotate the body of rod 1 and make 3 tip butt of anti-rotation pin on derailleur casing 5, compare in drive shaft 4, the body of rod 1 weight is lighter, and it is more convenient to align the regulation. The rotation of the right side gear 21 is restricted by the abutment of the rotation-preventing pin 3 with the transmission case 5, and accordingly, the rotation of the planetary gear 23 in the case engaged with the right side gear 21 is restricted, and further, the rotation of the left side gear 22 engaged with the planetary gear 23 is restricted, and then, the second external splines 41 of the drive shaft 4 are aligned with the second internal splines 221 of the left side gear 22, and the left side gear 22 can be loaded by slight circumferential rotation. Because the left side gear 22 is restricted to rotate in the assembling process, the assembly of the driving shaft 4 and the left side gear 22 is more convenient, and the assembly efficiency is improved on the premise of ensuring the correct assembly of the driving shaft.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
