High-Performance Elevator Gearbox

Reducer with mineral oil, the transmission efficiency is 87%; if with synthetic oil, the transmission efficiency is 92%.
Blending the most advanced design concept from home and abroad, fluid simulation was carried out on the shell, the structure is optiomized to the utmost.
The special circular structure makes the heat dissipation better.
Using the structure of inhead type. High speed shaft and main shaft oil seal lip were higher than the oil level line. Avoid oil spilling. No oil spill risk.
Using high precision worm gear transmission, the characteristics of damping performance is excellent.
Running with the 43% duty of the rated load (2T cage & 2T load), the temperature rise of the reducer is 45K.
The fever of High speed spindle bearing is the most serious. Torindrive use special high precision ball bearings instead of the commonly used roller bearing and unique internal circulation cooling lubrication system, the cooling effect of reducer is better.

Make full use element analysis (FEA) to analyze the mechanical load, the stress the deformation of the reducer parts. Thus, the reducer structure is designed reasonably, the safety factor is greatly increased and the design life is ensured to more than 8 years.
