Description

Technical Field

[0001] This utility model relates to the field of bearing ring processing technology, specifically a lightweight new energy vehicle motor bearing structure. Background Technology

[0002] In the field of new energy, motor and bearing technologies are core components for achieving efficient energy conversion and reliable operation. Modern motors use high-density permanent magnet materials, optimized electromagnetic design, and advanced cooling technology to significantly improve power density and efficiency. Meanwhile, bearing technology, through ceramic hybrid materials, intelligent lubrication systems, and precision manufacturing processes, effectively reduces friction loss and extends service life. These technological innovations provide highly reliable and low-energy-consumption solutions for applications such as new energy vehicles and wind power generation, driving the new energy industry towards a more efficient and environmentally friendly direction.

[0003] However, it still has some drawbacks. For example, the motors and bearings of new energy vehicles mostly use solid metal structures, which are heavy and lead to increased energy consumption of the whole vehicle. Although the solid design of traditional ball bearings and shells can ensure strength, the material utilization rate is low and there is a lack of optimized stress distribution design. Existing lightweight solutions are often achieved by simply reducing the material thickness, which can easily lead to a decrease in load-bearing capacity or a shortened fatigue life.

[0004] To address the aforementioned issues, this application proposes a lightweight bearing structure for electric motors in new energy vehicles. Utility Model Content

[0005] The purpose of this utility model is to provide a lightweight bearing structure for new energy vehicle motors to solve the problem of insufficient lightweight design of new energy vehicle motors and bearings mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a lightweight new energy vehicle motor bearing structure, including a motor front panel, a motor housing fixedly connected to one side of the motor front panel, a honeycomb-shaped outer shell layer installed on the four sides of the motor housing, and four sets of the honeycomb-shaped outer shell layer, a lightweight bearing movable inside the motor front panel, and honeycomb-shaped ball bearings installed inside the lightweight bearing. The honeycomb-shaped outer shell layer and the honeycomb-shaped ball bearings facilitate the reduction of the weight of the motor and bearing. This biomimetic structure can reduce the amount of material used while ensuring mechanical strength, thus achieving a lighter weight. The honeycomb-shaped outer shell layer and the honeycomb-shaped ball bearings, through the force distribution of the honeycomb shape, maintain good load-bearing performance while reducing weight. The lightweight design not only improves the lightweight capability of the equipment, but also ensures operational stability.

[0009] Preferably, the inclined panels are provided in multiple sets and installed in a cross pattern, and the straight panels are fixedly connected inside the multiple sets of inclined panels. A honeycomb groove is formed between the multiple sets of inclined panels and the straight panels, which serves to reduce weight by hollowing out the panels.

[0010] Preferably, the lightweight bearing has a raceway inside, and honeycomb balls are installed inside the raceway. Multiple sets of honeycomb balls are provided, and the surface of the honeycomb balls is composed of a honeycomb-shaped porous shape, which helps to reduce weight.

[0011] Preferably, the lightweight bearing has a bearing hole on its inner wall, and a movable shaft is installed inside the bearing hole. The shaft is installed inside the motor housing, and an armature core is installed on the surface of the shaft. A ring-shaped magnetic flux is installed on the surface of the armature core. The honeycomb outer shell layer and honeycomb balls are based on biomimetic design and material mechanics optimization. The honeycomb outer shell layer achieves efficient material distribution through the honeycomb groove structure formed by the intersection of inclined and straight panels. Its polygonal unit structure, like a honeycomb in nature, has an excellent strength-to-weight ratio, can evenly distribute external loads and reduce stress concentration. The honeycomb balls adopt a porous honeycomb surface design, reducing mass through internal hollowing while retaining the contact area between the honeycomb balls and the raceway, ensuring the stability of load transmission. Both utilize the geometric characteristics of the honeycomb structure to form a multi-directional support network under axial and radial forces, reducing weight while maintaining the original load-bearing stiffness through structural compensation, meeting the dual requirements of lightweight and high reliability for new energy vehicle motors.
