2. Product Features
1. Lightweight and high strength coexist: Aviation-grade aluminum alloy is selected, and the density is only one-third of that of steel, which effectively reduces the overall weight of medical equipment and facilitates the movement and installation of equipment. At the same time, through special heat treatment process, it has excellent tensile strength and fatigue resistance, and can maintain stable performance in long-term high-frequency operation to meet the continuous working needs of medical equipment.
2. High-precision transmission: Using advanced processing technologies such as CNC milling and wire cutting, the pulley tooth profile accuracy reaches ISO 5 standard, the pitch error is controlled within ±0.02mm, and it is tightly meshed with the synchronous belt. There is no slip during the transmission process and the transmission ratio is constant. Ensure that medical equipment such as the movement of the mechanical arm of the CT scanner and the operation of the components of the ventilator are accurate and correct, and improve the reliability and safety of the operation of medical equipment.
3. Good corrosion resistance: The surface of the aluminum alloy is anodized to form a dense oxide film, which has excellent corrosion resistance and can effectively resist the erosion of common disinfectants, body fluids and other substances in the medical environment, avoiding corrosion damage to parts that affect the operation of the equipment and extending the service life of the equipment.

4. Low-noise operation: The unique structural design and precision manufacturing process make the noise of the pulley less than 45 decibels when running at high speed, creating a quiet atmosphere for the medical environment, without interfering with the diagnosis of medical staff and the rest of patients, and is especially suitable for medical scenarios that are sensitive to noise.

III. Product details
1. Material and processing technology: The main body is made of 6061-T6 or 7075-T6 aluminum alloy. 6061-T6 aluminum alloy has good comprehensive performance, medium strength, good corrosion resistance and weldability, and is suitable for most medical equipment transmission parts; 7075-T6 aluminum alloy has higher strength and is often used in high-end medical equipment with strict mechanical properties. After the pulley is formed, the material strength and hardness are improved through solid solution treatment and artificial aging treatment; the surface anodizing treatment not only enhances corrosion resistance, but also can be customized in different colors according to needs, which is convenient for the distinction and management of medical equipment.
2. Manufacturing process: Use a five-axis linkage machining center for high-precision cutting to ensure the precise size of each part of the pulley. Laser cutting technology is used to process the tooth shape to ensure accurate tooth profile shape and uniform tooth pitch. During the production process, the key dimensions and form and position tolerances of the pulleys are fully inspected by a three-coordinate measuring instrument to strictly control product quality and ensure that each pulley meets the high-precision use requirements of medical equipment.
3. Application areas: In medical imaging equipment, it is used to drive the movement of the examination bed and the rotation of the detector of CT and MRI equipment to ensure accurate positioning during the inspection process; in rehabilitation equipment, it provides stable power transmission for electric rehabilitation training equipment to assist patients in rehabilitation training; in intelligent surgical robots, as a key transmission component, it realizes the precise control of the robotic arm and improves the accuracy and safety of surgical operations.
