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 equivalent number of teeth of helical rack?
When milling helical rack, the tool number should be selected according to the equivalent number of teeth. Do you know what is the equivalent number of teeth of helical rack? Let's introduce the gear pinion to you.
Cylindrical gear is a common type of gear
The gear has straight teeth and is parallel to the axis of the wheel. Cylindrical gear is a common type of gear. The advantages of spur gears are simple design, economical manufacture and maintenance, and no end thrust. They apply radial loads to the bearings. Gears are called slow gears. If noise is not a serious design problem, gears can be used at speed.
An effective method to improve the accuracy of gears
Grinding is a kind of precision machining technology when other metal cutting methods are not satisfied with the requirements of workpiece precision and surface roughness. The basic principle of lapping is to take part in the abrasive between the workpiece and the workpiece, or between the lapping tool and the workpiece. Under a certain pressure, the abrasive in the abrasive carries out micro cutting on the workpiece.
The method of high precision gear processing
There are still many ways to process high-precision gears. Let's not introduce them one by one. Let's simply talk about the continuous indexing generation method!
Gear transmission is a common transmission method in mechanical equipment
Gear transmission is a common transmission method in mechanical equipment, which is widely used in all walks of life.
