Planetary gears, also known as epicyclic gears, are a type of gear system that consists of a central sun gear, planet gears, and an outer ring gear. This configuration allows for compact, efficient, and versatile power transmission.
Main process: turning, hobbing, shaving, carburization heating, shot blasting and grinding
Turning: using Mazark CNC turning machine, get a specific dimension and fine surface.
Gear hobbing: is a gear manufacturing method to cut teeth into the blank with a hob, all of our hobbing and shaving are automatic, make sure high accuracy of teeth profile and lead.
Gear shaving: removes small amounts of metal from the working surfaces of gear teeth. correct errors in index, helical angle, tooth profile. teeth shaving process can also improve tooth surface finish. Shaving provides for form modifications that reduce gear noise. These modifications can also increase the gear’s safety and life.
Gear heating: our Ipsen furnace through carburizing to get high wear-resistance and hardness, keep the gear have more stable fine metal structure.
Gear grinding: the process of finish grinding gear teeth, and is a critical step when manufacturing high precision gear.
Material: 20CrMnTi, 20CrNiMo(AISI 8620) or other alloy steel
Module: 0.8-8 mm Hardness: 58-62HRC Case depth: 0.8-1.2 mm
Features of Planetary Gears
- Compact Design: Planetary gears have a high power density, meaning they can transmit significant torque in a small space. This makes them ideal for applications where space is limited.
- High Efficiency: Due to the distribution of load across multiple planet gears, planetary systems experience less friction and energy loss, resulting in high efficiency (often above 95%).
- Load Distribution: The load is shared among multiple planet gears, reducing stress on individual components and increasing the system’s durability and lifespan.
- High Torque Transmission: Planetary gears can handle high torque loads due to the even distribution of forces across the gears.
- Versatility in Speed and Torque: By fixing different components (sun gear, ring gear, or carrier), planetary gears can achieve various speed and torque ratios, making them highly adaptable.
- Smooth Operation: The multiple contact points between the gears result in smoother and quieter operation compared to traditional gear systems.
