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;
What is the meaning of piston rod outer diameter tolerance and analysis of problems
The piston rod of the oil cylinder is 40, the cylinder diameter is 50, and the stroke of the oil cylinder is 1480?
Introduction of stainless steel piston rod
Stainless steel piston rod is mainly used for piston rod of hydraulic and pneumatic, engineering machinery, automobile manufacturing, guide pillar of plastic machinery, roller of packaging machinery and printing machinery, axis of textile machinery and conveying machinery, and linear optical axis of linear motion.
