The principle of harmonic gear
Time:2020-06-11 From:admin Hits: 344
The principle of reducer: the process of meshing the flexible gear teeth and the rigid gear teeth at the pitch circle is like two pure rolling (non-slip) rings. At any instant, the arc length on the pitch circle must be equal. Because the flex wheel has two pitches less than the rigid wheel in the pitch circle length, the flex wheel must rotate through the two tooth pitch angular displacements relative to the rigid wheel during the meshing process. This angular displacement is the rotation of the output shaft of the reducer , So as to achieve the purpose of deceleration.
Structural features: small size, light weight, large transmission ratio, high precision, stable transmission and high efficiency
Application fields: light industrial robots/manipulators, precision measuring devices, precision transmission systems that require volume
Components:
Harmonic reducer lubrication requirements
Extreme pressure abrasion resistance:
The harmonic reducer needs to start and stop frequently and reciprocate frequently, which is easy to produce wear and lead to reduced accuracy. Therefore, the grease must have excellent extreme pressure anti-wear performance.
Thermal stability:
The joint structure of industrial robots is compact, and the heat dissipation is poor. Continuous working for a long time causes the joint temperature to be high. The grease is required to have good thermal stability and oxidation stability.
long life:
Harmonic reducers need to be frequently started and reciprocated in a small space to withstand high-speed and high-load operation, which requires grease to have long-life lubrication, no carbon deposition, no color change, and no oil separation.
Noise reduction:
Harmonic reducer will generate strong noise due to friction, vibration and collision of transmission gears. The grease must have extremely strong oil film thickness and adhesion to effectively reduce noise.
Comparison of grease wear scar diameter
DRSLSK-1A grease uses synthetic oil as the base oil, which has better low temperature performance and lubricating performance; organic molybdenum compound additives have excellent anti-wear extreme pressure performance, and will not corrode metals, which can effectively improve harmonic gears The service life of the box.
