Common types of gear units 1) the main features of worm reducer is a reverse self-locking function, GCWS400 worm reducer, can have a greater reduction ratio, the input shaft and output shaft are not on the same axis, not in the same plane on. But generally larger, the transmission efficiency is not high, accuracy is not high. 2) Harmonic reducer harmonic drive is controlled using a flexible element is elastically deformed to pass the motion and power, small size, high accuracy, but the downside is limited flexible wheel life, the impact of intolerance, GCWS500 worm gear inferior to machines, rigidity and metal. Input speed is not too high. 3) the advantage of planetary gear structure is compact, small backlash, high precision, long life, rated output torque can do great. But the price is slightly more expensive. Reducer: in short, the general power of the machine is designed and manufactured, its rated power does not change, then, the greater the speed, the torque (or torque) is smaller; the smaller the speed, worm reducer, the torque increases. WPA cast iron worm gear performance characteristics: 1, box structure as a whole, GCWS450 worm reducer, elegant appearance, good rigidity. 2, box type as the basic type (box for the vertical or horizontal structure with two bottom foot) and the universal type (box is rectangular, multi-faceted with a fixed screw hole without a bottom foot or install another end foot and other structural type) 3, the input shaft is coupled manner basic type (single input shaft and dual input shaft), with motor flange two kinds. 4, the output shaft structure of the basic type (single output shaft and double output shaft) and two hollow output shaft. 5, the output, position and direction of the input shaft input shaft and the next; the output axis and down; input axis and down. 6, can be 2 or 3 sets composed of multi-stage gear reducer, in order to get a great ratio. Two, WPA cast iron worm reducer working conditions: 1, a worm reducer worm speed can not exceed 1500r / min. 2, the working environment temperature -40 ℃ - + 40 ℃, when the working environment temperature below 0 ℃, before starting the oil must be heated to above 0 ℃, when the working temperature is higher than 40 ℃, cooling measures must be taken. 3, worm gear reducer can be positive and negative rotation of the shaft. Third, cast iron worm reducer WPA Note: 1, the worm shaft must not make use of the input shaft. 2, matching motor (ie power) can not exceed the values ??specified label.
