A planetary reducer is a widely used legacy device that reduces speed.The planetary reducer mainly realizes the transmission accuracy through the cooperation between the gears.Many people do not understand the backflow clearance rate of planetary reducers.Zhuozhuang transmission technology editor will give you a short introduction.
The gap refers to the gap between the gears, and the gap between the gears is usually called the return clearance rate, also known as the return clearance rate.The lower the return gap (or return clearance rate) in the neutral energy parameter of the planetary reducer, the higher the transmission accuracy, the higher the price, and the higher the price, the higher the transmission efficiency (the unit is Arcmin, usually called high precision Types below 3, low-precision types above 15).
Backlash: Fix the input end, and rotate the output end clockwise and counterclockwise.When the output end has 2% of the rated torque of 2%, the output end of the reducer has a small angular displacement, which is called the return clearance, also known as 'Back Clearance'.The unit is 'minutes' of 'Arc', which is 1/60 of a degree.
'arc' minutes of precision for planetary reducers:
Arcmin [arcmin]: Once divided into 60 Arcmin (= 60 Arcmin = 60') If you mark the return gap as 1 Arcmin, it means that the reducer rotates one turn and the angular deviation at the output is 1/60°.In practice, this angular deviation is related to the shaft diameter, b = 2·π·r·a°/360°.That is to say, when the radius of the output end is 500mm and the precision of the gearbox is JT = 3', that is, A° = 3/60, the deviation of the reducer of the one-rotation revolution is B = 0.44mm.
The above is the basic knowledge of the backflow clearance rate of the planetary reducer.The planetary reducer produced by Zhuochuang Transmission Technology has a single-stage accuracy of no more than 2 arc minutes, and a double-stage accuracy of no more than 4 arc minutes.Generally, the accuracy is very high and the quality is good.
