          Reverse design of automotive transmission shaft

          Automotive drive shaft reverse design case

          The automotive drive shaft can transmit power between two shafts of different axes, even between two shafts whose relative positions are constantly changing during operation. A circular object that can be moved or rotated by attaching or assembling various accessories is an important safety part of the car.

          Practical problems

          1. The accuracy of the hole position of the drive shaft (the relative position of the hole and the hole) should be guaranteed, not exceeding 0.05mm.

          2. The wall thickness and reinforcing structure of the force transmission part of the automobile transmission shaft are the key points of the design, and the design result directly affects the service life of the product.

          3. The data density collected by the traditional measurement method is not enough (the data volume is insufficient) and the surface of the automobile transmission shaft cannot be measured, and the secondary design cannot be performed in the later stage.

          Automotive drive shaft scanning site

          For the problems faced by customers, Hualang 3D engineers proposed solutions: Handheld 3D scanner HL-3DH-3M (quickly obtain high-precision 3D data of automotive transmission shaft) + Reverse design software Geomagic Studio (Automobile drive shaft) Cloud data is converted into triangular mesh surface data) +Pro/E, UG and other mainstream design software for post-processing, speeding up the secondary design of the car drive shaft.

          1. Preparation in the early stage:

          Spraying the developer: Improve the background color contrast of the sample surface for better scan data.

          Paste mark points: Make the acquired data be positioned and stitched in the scanning software.

          2. 3D scanning:

          Hualang 3D engineers use the handheld 3D scanner HL-3DH-3M to quickly obtain high-precision 3D data of the car's drive shaft. The three-dimensional scanner has the characteristics of small size, light weight, simple operation, fast scanning, and no external AC power supply. Fast 3D scanning of the car's drive shaft for high-density point cloud data. It takes only 10 minutes to get 3D data of the car's drive shaft with an accuracy of 0.05mm. The three-dimensional data of the automobile drive shaft is imported into the mainstream reverse software such as Pro/E and UG for post-processing, speeding up the secondary design of the truck top cover, providing reliable parameters to other relevant departments, ensuring that the design results fully meet the production requirements and speeding up. Production of automotive transmission shafts.
