Principle of planetary£♣¥ reducer: The driving source (motor) s>λπ♦tarts the sun gear in♦✘ a direct connection, and t> he sun gear drives the p☆ lanetary gears assembled on ¶ the planetary gear carrier. The entirσ↑e planetary gear system au✔"tomatically rotates along the outer geσ>↓δar ring, and the planetary carr®←₩✔ier connects the output ±¶©<shaft to achieve the purpose of accel•&eration. Higher reduction ratγ↔ios require multiple s♥£γets of stage gears anσ÷d planetary gears to be multip ∞lied and accumulated.
Structural features: compacΩΩt structure, good heat exc ✘↔≥hange, high precision, hig↔✔☆h transmission efficienc$♦↑©y, strong applicability, lifelong m✔$δ₹aintenance-free
Application areas: Mechanical reductio✘≠∞φn devices for process equipment in↑ ₩β many industries and fields such as meσ±tallurgy, mining, transportation, ♣∞water conservancy, chemical i∑↕αndustry, food, beverage, texti≥∏∏♥le, tobacco, packaging, and environment↑σπφal protection.
Component composition:
Planetary reducer requirements ★αfor grease:
Wear resistance: Reduce wear ±←$₽and temperature rise, meet the ne÷&☆eds of lifelong lubrication of reduce& ↓rs
Noise reduction: Improve product com♣↑fort
Adhesion performance: M☆→πaintain a uniform oil film ♣♥♥on the metal surface, reduce wear a←∞nd noise
Mechanical stability: Pre¥vent grease from softenin★♠g after shearing, resu☆σ©®lting in oil seepage and leakage
High and low temperature performance:βσ↔↕ Reduce low-temperature starting✘≤ torque and high-tem✘λεperature softening under high loδ∞ad conditions
Company’s solution for plan€∑etary gearboxes:
Our company uses unique polyurea thicke↓±πner, refined synthetic ★¥ oil, and special extreme pressure an∏∞&ti-wear agent, which has good←>≠ high and low temperature pφ'≥erformance, small star∏∞ting torque at low temp↕¥erature, no coking at high temperature,'₹§± and good shearing performance. U±β¥≠nder high temperature and extreme press↓σ∏ure conditions, the structure is not ea♣Ωsy to be damaged, the"¥>™ structure is stable, and γ↑∏ it has good adhesion to the meta₹£l surface.
