Background
The principle of the planetary reduction gear is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of a motor to a desired number of revolutions and obtain a large torque. The gear with less teeth on the transmission shaft of the planetary reducer is meshed with the big gear on the output shaft to achieve the purpose of speed reduction. The common speed reducer also has several pairs of gears meshed with the same principle to achieve ideal speed reducing effect, and the ratio of the number of teeth of the big gear and the small gear is the transmission ratio. The planetary reducer is an industrial product with wide application, the performance of the planetary reducer can be compared with that of other military grade speed reducer products, but the planetary reducer has the price of the industrial grade product, and the planetary reducer is applied to wide industrial occasions. The P-series planetary reducer has the reduction ratio of 25-4000 r/min (the P-series planetary reducer can achieve a larger speed ratio by combining with R, K series), the output torque is as high as 2600000Nm, the motor power is 0.4-12934kW, the product installation forms comprise foot installation, flange installation, torsion arm installation, shaft output modes such as a solid shaft, an involute spline solid shaft and the like, and the planetary reducer is widely applied to a slewing mechanism, a roller press, a bucket wheel machine, a baffle plate conveyor belt machine, a separator, an aerator, a traveling drive reducer, a steel belt rotating grinding mill, a rotary kiln and the like.
