Browse our primary high-precision helical gears, plastic planetary gearboxes, and micro DC motor assemblies engineered for smart consumer appliances and industrial automation.
In mechanical transmission design, helical gears are preferred over traditional spur gears due to their continuous, gradual meshing teeth geometry. Unlike spur gears, where teeth engage all at once, helical gear teeth engage progressively. This reduces impact loading, minimizes vibration, and provides a quiet operation essential for modern micro-drive applications.
Kineto Motor brings twenty years of industrial experience to design and export customized micro helical gear systems. Modern smart devices require small components that do not compromise torque density or noise control. In applications like smart door locks, medical instruments, pop-up cameras, and robotic drive trains, plastic and metal micro-helical gears run smoothly under tight design limits.
Our commitment to modern engineering is visible throughout our product life cycle, from tool steel mold design and micro-molding plastic selections to coordinate measurement systems. We balance cost, volume consistency, and high quality to deliver transmission components that meet strict performance requirements.
Understanding chemical properties and structural engineering parameters when selecting materials for micro helical gears.
Polyoxymethylene offers high stiffness, low friction, and excellent dimensional stability. POM gears resist wear, absorb minimal moisture, and perform consistently in diverse environments. This makes them ideal for micro-gears in high-efficiency smart appliances.
Nylon 66 provides exceptional mechanical strength and impact resistance. It absorbs vibrations and handles shock loads without structural failure. Fiber-reinforced nylon compounds (e.g., glass-filled PA66) are used in high-torque gear racks and drive mechanisms.
For high-temperature and chemically corrosive environments, we formulate custom polymer blends. Polycarbonate (PC) provides impact strength, while Polyether ether ketone (PEEK) is used in challenging automotive and medical applications.
