Description

Technical Field

[0001] This utility model relates to the field of heavy-duty truck axle technology, specifically a high-efficiency and lightweight differential bearing disassembly tooling assembly. Background Technology

[0002] The differential is an indispensable component on the axle of a heavy-duty truck. It is specifically designed to adjust the speed difference between the left and right wheels, allowing the left and right (or front and rear) drive wheels to rotate at different speeds. The differential ensures that the drive wheels on both sides undergo pure rolling motion, preventing wheel slippage. Wheel slippage not only accelerates tire wear, increases power and fuel consumption, but also makes steering difficult and reduces braking performance.

[0003] The differential bearing is one of the core components of the differential, pressed onto the differential housing. However, a persistent problem has been its difficulty in removal once it is installed. This is because the remaining annular area on the bearing inner ring, which provides leverage for disassembly, is extremely limited after the inner ring is pressed onto the housing. In reality, due to quality issues, after-sales problems, or other reasons, there are many situations where the differential bearing needs to be disassembled. Usually, workers use chisels and hammers, expending considerable effort and time to knock the bearing off, often resulting in damage to both the bearing and the differential housing. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a high-efficiency and lightweight differential bearing disassembly tooling assembly.

[0005] The technical solution provided by this utility model is: a high-efficiency and lightweight differential bearing disassembly fixture assembly, characterized in that it consists of a mounting platform, support legs, and a pressure head; the support legs are provided under the mounting platform; the mounting platform includes a loading surface, on which large and small arc cuts are respectively opened on the left and right sides, the large and small arc cuts having different diameters and located on the center line of the loading surface; a cut is made on the loading surface, the cut being tangent to both the large and small arc cuts; the cuts, the large and small arc cuts form a vertically open cut on the mounting platform, the cut having a centrally symmetrical structure; the pressure head is a solid cylindrical structure, independent of the mounting platform and support legs, and stored together.

[0006] Furthermore, two vertical ribs perpendicular to the loading surface are provided on both sides of the loading platform.

[0007] Furthermore, the number of support legs is four; the support legs are round bar structures, symmetrically installed at the four corners of the pressing table, and fixed together with the lower plane of the pressing table.

Vertical ribs are provided on both sides of the press-fitting table to ensure that the pressed bearing will not easily fall off, providing a safety protection function. Attached Figure Description

[0013] In the diagram, 1 is the loading platform, 2 is the support leg, 3 is the pressure head, 11 is the loading surface, 12 is the vertical rib, 13 is the large arc cut, 14 is the small arc cut, and 15 is the cut. Detailed Implementation

[0014] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings.

[0015] like Figure 1 , 2As shown in Figures 3 and 4, a high-efficiency and lightweight differential bearing disassembly fixture assembly consists of a mounting platform 1, support legs 2, and a pressure head 3. The mounting platform 1 is machined with a loading surface 11. Large arc cuts 13 and small arc cuts 14 of unequal diameters are machined on the loading surface 11, both located on the center line of the loading surface 11. Cuts 15 are machined on the loading surface 11, tangent to both the large arc cuts 13 and the small arc cuts 14. The cuts 15 and the large arc cuts 13 and 14 form a large arc cut on the mounting platform 1. The pressure table 1 has two open cuts, each with a different diameter, forming two arcs on the left and right sides. The cuts are tangent to the left and right ends in the middle and are centrally symmetrical. Two vertical ribs 12 with a small height are machined on both sides of the pressure table 1, perpendicular to the loading surface 11. Four support legs 2 are machined into round rod structures and symmetrically welded to the four corners of the lower plane of the pressure table 1, and fixed together with the lower plane of the pressure table 1. The pressure head 3 is machined into a solid cylindrical structure and is stored together with the pressure table 1 and support legs 2 as an independent unit.

[0016] This utility model discloses a high-efficiency and lightweight differential bearing disassembly fixture assembly. During operation, the mounting platform 1 and support legs 2 are placed on the worktable under the hydraulic press. The bearing and differential housing assembly is introduced from bottom to top into the mounting platform 1 through the large arc cut 13 on the mounting platform, so that the inner ring of the bearing is higher than the loading surface 11. Then, the bearing and differential housing assembly is translated along the axis towards the small arc cut 14. As the cut gradually decreases, a certain position between the large arc cut 13 and the small arc cut 14 can be used to support the small annular contact surface remaining after the bearing is assembled onto the differential housing. At this time, the bearing and differential housing assembly is stably placed on this fixture. The pressure head 3 is placed on the differential housing. The cross-sectional diameter of the pressure head 3 is smaller than the outer diameter of the cross-section of the differential housing at the bearing mounting position, but larger than the cross-sectional bore diameter of the differential housing at that position. The hydraulic press is used to align the pressure head 3 and press it down directly to complete the disassembly of the differential bearing.
