Technical parameters and classification introduction of precision planetary reducer

 Technical parameters and classification introduction of precision planetary reducer: For many people, they only know the purpose of precision planetary reducer, but do not know the relevant technical parameters of this product, and how the precision planetary reducer is classified, below, small The editor will give you a detailed introduction.

Technical parameters of precision planetary reducer

Reduction ratio: the input speed is higher than the output speed.

Number of stages: the number of sets of planetary gears.Since one set of planetary gears cannot meet the larger transmission ratio, sometimes two or three sets of planetary gears are needed to meet the requirements of users for larger transmission ratios.Due to the increase in the number of planetary gears, the length of the two-stage or three-machine reduction stage will increase, and the efficiency will decrease.
Full load efficiency: Refers to the transmission efficiency of the reducer in the case of a large load (the output torque is stopped by a fault).
Average life: refers to the continuous working time of the reducer under rated load and high input speed.
Rated torque: a standard for reducers.Under this value, when the output speed is 100 rpm, the life of the reducer is the average life.Over this value, the average life of the reducer will be reduced.When the output torque exceeds twice this value, the reducer malfunctions.
Lubrication method: no lubrication is required.The reducer is fully sealed, so there is no need to add grease during the entire service life.
Noise: The unit is decibels (dB).This value is measured when the input speed is 3000 rpm, without load, and one meter away from the reducer.

Return clearance: Fix the output end and rotate the input end clockwise and counterclockwise to make the output end produce rated torque +-2% torque, there is a slight angular displacement at the input end of the reducer, and this angular displacement is the return clearance.The unit is "minutes", which is one-sixtieth of a degree.The usual return clearance value refers to the output end of the reducer.

Classification of precision planetary reducer

According to the output direction, there are two main types: linear type and right-angle type;
按级数分一般有三种：一级减速（一般为小于10：1）、二级减速（一般为大于10：1而小于等于200：1）、三级减速（有的品牌没有第三级，大减速比做到100：1，一般划分原则就是大于100：1），但微型行星减速器可做到五级，减速比大做到4592：1；
According to the purpose: military and civilian;
According to operating environment: standard environment, low temperature environment, clean room environment and vacuum environment;
According to the precision: standard precision and high precision and ultra-precision level;
According to the place of origin: domestic, imported, domestic assembly;
and many more.
Widely used in precision machinery manufacturing equipment, numerical control equipment, military systems, etc.
Almost all planetary reducers are a combination of three planetary gears and one sun gear.
The difference in various applications leads to different choices of products. The choice of which brand and product mainly depends on the actual application.
