In the wholesale of reduction gearboxes, we need to have a clearer understanding of the working principle of the reducer and its assembly so that we can more clearly choose products suitable for ourselves.
A special device for converting a higher to a lower speed.Due to the input shaft and output shaft gear tooth gear mesh together, and the input shaft wheel tooth number is less than the output shaft of the big gear wheel gear, according to the gear ratio is inversely proportional to the revolution than, when power source, such as machine or other transmission mechanism of high-speed movement, through the input to the output shaft, gear shaft and output shaft got lower than the input shaft of low-speed movement, so as to achieve the aim of slowing down.
Assembly parts: 1. Box body and lid
The box body and the box cover are the supporting parts and the subsuming parts of the transmission parts of the reducer. The structure is complex. The box body bears pressure and requires good steel degree, vibration damping and sealing.The lid and body of the box shall be made of grey cast iron in a small batch and cast by hand.Or carbon structure steel, manual arc welding from.In mass production, gray cast iron is used and cast by machine molding.
Shaft, gear shaft and gear wheel
The shaft, gear shaft and gear wheel are important transmission parts of the reducer. The shaft rod of the shaft and gear wheel shaft is subjected to the combined action of short bending and short twisting.Gear shaft and gear tooth part of the greater contact stress and bending stress, should have good wear resistance and higher strength.When a single piece is produced, medium carbon steel (45 steel) can be formed by free forging or die forging, or by turning the round steel bar of medium carbon steel.Medium carbon steel is formed by die forging in mass production.
3. Rolling bearing
The rolling bearing in the reducer is subjected to radial and axial compressive stress, which requires higher strength and wear resistance.The rolling bearings are standard parts, the inner and outer rings are forged by GCrl5, the ball bearings are helical helical cross-rolling, and the cage is stamped by high quality carbon structural steel (08 steel).
