Lubrication solution for planetary motor reducer

Principle of planetary reducer: The driving source (motor) starts the sun gear in a direct connection, and the sun gear drives the planetary gears assembled on the planetary gear carrier. The entire planetary gear system automatically rotates along the outer gear ring, and the planetary carrier connects the output shaft to achieve the purpose of acceleration. Higher reduction ratios require multiple sets of stage gears and planetary gears to be multiplied and accumulated.

Structural features: compact structure, good heat exchange, high precision, high transmission efficiency, strong applicability, lifelong maintenance-free

Application areas: Mechanical reduction devices for process equipment in many industries and fields such as metallurgy, mining, transportation, water conservancy, chemical industry, food, beverage, textile, tobacco, packaging, and environmental protection.

Component composition:

Planetary reducer requirements for grease:

Wear resistance: Reduce wear and temperature rise, meet the needs of lifelong lubrication of reducers

Noise reduction: Improve product comfort

Adhesion performance: Maintain a uniform oil film on the metal surface, reduce wear and noise

Mechanical stability: Prevent grease from softening after shearing, resulting in oil seepage and leakage

High and low temperature performance: Reduce low-temperature starting torque and high-temperature softening under high load conditions

Company’s solution for planetary gearboxes:

Our company uses unique polyurea thickener, refined synthetic oil, and special extreme pressure anti-wear agent, which has good high and low temperature performance, small starting torque at low temperature, no coking at high temperature, and good shearing performance. Under high temperature and extreme pressure conditions, the structure is not easy to be damaged, the structure is stable, and it has good adhesion to the metal surface.

Test products	Helical planetary reducer, spur planetary reducer (*Kai 80 type, first level)
Test equipment	Decibel meter, infrared thermometer, servo motor

Test requirements:

1. Temperature rise ≤75℃,

2. Noise ≤65Db,

3. The oil film on the tooth surface is intact

 

Test process: Reducer type: helical gear (grease amount: 25g)

Oil film condition

Reducer type: straight teeth (grease amount: 20g)

Oil film condition

 

Test results:

Judging from the test records, using grease test, the temperature rise, noise and oil film conditions of the two types of planetary reducers are good, meeting the manufacturer’s requirements.
