Planetary reducer principle: The drive source (motor) starts the sun gear in a directly connected manner, and the sun gear will drive the planet gear combined with the planet gear carrier. The entire set of planetary gear system automatically rotates along the external gear ring, and the planetary carrier is connected to the output shaft to achieve acceleration. A higher reduction ratio needs to be accumulated by multiplying multiple sets of stage gears and planetary gears.
Structural characteristics: compact structure, good heat exchange, high precision, high transmission efficiency, strong applicability, maintenance-free for life
Application areas: mechanical deceleration devices for process equipment in many industries and fields such as metallurgy, mining, transportation, water conservancy, chemical industry, food, beverage, textile, tobacco, packaging, environmental protection, etc.
Components composition:
Planetary reducer requirements for grease:
Wear resistance: reduce wear and temperature rise to meet the life-long lubrication needs of the reducer
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, and oil leakage
High and low temperature performance: reduce low temperature starting torque and high temperature softening under high load conditions
Hecheng company’s solution for planetary gearbox:
Our company selects a unique polyurea thickener, refined synthetic oil, and added a special type of extreme pressure antiwear agent, which has good high and low temperature performance, low starting torque at low temperature, no coking at high temperature, and good shearability In the case of high temperature and extreme pressure, the structure is not easy to damage, the structure is stable, and it has good adhesion to the metal surface layer.
