Helical Plastic Gear with Internal Threads
This is a helical plastic gear featuring internal threads. Precision-molded from engineering plastic, it combines a helical gear profile on the outside with an integrated threaded hole on the inside, serving as a composite structural transmission component.
1. External Helical Gear Structure: Helical gear meshing ensures smooth, low-noise transmission; capable of withstanding continuous alternating torque with high transmission precision.
2. Integrated Internal Threaded Hole: The gear and threaded structure are combined into a single part, eliminating the need for a separate nut. It enables axial movement, lifting/lowering adjustment, and locking/positioning through direct threaded engagement, converting rotary motion into linear motion.
3. Integrated Injection Molding: The complex composite structure is formed in a single molding process, reducing part counts and simplifying customer assembly; ideal for mass production.
4. Self-Lubricating Plastic: The gear surfaces provide inherent lubrication during operation, resulting in low noise and wear resistance; suitable for medium-load applications.
Driven by a motor, the gear utilizes its internal threaded interface to convert rotary motion into axial linear displacement, enabling functions such as lifting, pushing, adjusting, and locking.
• Automotive Industry: Headlight height adjustment motors, seat lift mechanisms, rearview mirror adjustment, and air damper actuators; utilizing threads for displacement adjustment.
• Home Appliances: Coffee machines, food processors, range hoods, projector lens lift modules, and robot vacuum lift mechanisms.
• Office Equipment: Lift and adjustment components for printers and scanners.
• Smart Equipment: Security camera focusing mechanisms, as well as lift and push actuators for small-scale equipment.
This helical plastic gear with internal threads combines smooth, low-noise helical transmission with integrated threading for rotary-to-linear motion conversion. Produced via integrated injection molding, it is used in various micro-actuators for adjustment and lifting, serving the automotive, home appliance, and smart office equipment sectors.
