Introduction to two common gear processing principles

The gear processing process roughly goes through the stages of blank heat treatment, gear blank processing, tooth profile processing, tooth edge processing, tooth surface heat treatment, fine datum correction and gear profile finishing. There are two common gear processing principles. It is a modeling process, a model research process and a model analysis process. The gear processing process roughly goes through the stages of blank heat treatment, gear blank processing, tooth profile processing, tooth edge processing, tooth surface heat treatment, fine datum correction and gear profile finishing.

Introduction to the tooth profile of precision gear and the shape classification of gear

Precision gears can be classified according to tooth shape, gear structure shape, tooth line shape, tooth surface and manufacturing technology.

High strength cylindrical gear with helical tooth line

The tooth line of helical gear is wound along the cylinder, which is a kind of cylindrical gear. Classified by gear shaft, helical gear belongs to parallel shaft gear.

Heat treatment forming process of gear casting

For forging process, general forming process can be used, and normal requirements can be considered; As for steel casting gears, such as driven gear, gear and idler gear, the molding process of quartz sand is a better choice. Since most of the positions of gears must be produced and processed, you do not need to apply higher forging technology; In addition, for medium and large section steel castings, gear processing plants basically select and apply the molding process of quartz sand.

What are the main failure modes of gear machining

Tooth surface damage: for the open transmission gear or the closed transmission gear with unclean grease, due to the relative drag between the meshing tooth surfaces, some hard abrasive particles enter the friction surface, which changes the tooth profile and increases the side clearance, resulting in excessive thinning of the transmission gear and tooth fracture. Under normal conditions, only when the lubricating grease is mixed with abrasive particles can the tooth surface abrasive particles be damaged in operation.

Causes of piston rod overheating

(1) When the piston rod and stuffing box are assembled, there is deflection, which causes local friction, so it should be adjusted in time;
