Description

Technical Field

[0001] The utility model relates to the technical field of main reducers, in particular to a novel practical fast gear inspection tool for a main reducer housing. Background Art

[0002] The final drive housing provides mounting support for the differential assembly and the driving and driven spiral bevel gear assemblies, securing these critical components. These components generate significant forces and vibrations during vehicle operation, and the housing must be able to withstand and stably secure them to ensure proper operation of the drivetrain. The final drive housing also plays a role in transmitting power within the drivetrain. Engine power is transmitted to the final drive via the drive shaft. As a load-bearing component, the housing must be able to withstand and effectively transmit this power, distributing it to the wheels and propelling the vehicle forward.

[0003] The final reducer housing is a crucial component of the automotive chassis, serving both as a fixed position and supporting element for the differential assembly and the driving and driven spiral bevel gear assemblies. This component is complex and requires high precision. To prevent gear interference during later assembly, a tool for rapid inspection is required. To address this issue, a new, practical, and rapid gear inspection tool for final reducer housings was developed. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides a novel practical and rapid gear inspection tool for a main reducer housing, aiming to improve the problem of gear interference in the prior art.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A new practical and rapid gear inspection tool for a main reducer housing includes a positioning unit, characterized in that: the top end of the positioning unit is rotatably connected to a transmission unit, the outside of the transmission unit is fixedly connected to an inspection unit, and the outside of the transmission unit is fixedly connected to a limit assembly;

[0007] As a further description of the above technical solution:

[0008] The limiting assembly includes a limiting block, the interior of which is fixedly connected to the exterior of the transmission unit;

[0009] As a further description of the above technical solution:

[0010] The transmission unit is made of high-strength aluminum alloy.

[0011] The utility model has the following beneficial effects:

[0012] 1. In the present invention, the transmission unit drives the inspection unit to rotate on the top of the positioning unit. Through the rotation, the tool actually simulates the motion trajectory of the gear, which can effectively inspect the inner cavity of the workpiece blank and prevent defective parts from flowing out, thereby avoiding gear interference problems in the actual assembly later.

[0013] 2. In the present invention, the inspection unit, the transmission unit and the limit block can be quickly assembled and disassembled, and the operation is convenient. This convenient assembly and disassembly operation method greatly saves operation time and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
