In mechanical design, the reference system (Basis System) is an important principle to determine the coordination relationship of parts, which directly affects the assembly accuracy, processing cost and the convenience of subsequent maintenance. Usually, the design engineer needs to make decisions b

H / js class:For easy disassembly, with additional locking force,The eccentricity of the centering parts does not cause vibration;It can replace the class H sliding fit when requiring a high centering accuracy.apply:Used for frequent disassembly and low coaxial requirements,When the matching surface

Grinding and hard cutting, two technologies that control key dimensions, each have advantages in terms of accuracy and efficiency. So which kind of processing method should we choose? This issue, let's talk about this topic:Grinding overviewGrinding is the cornerstone of precision machining and is k

In the gear transmission design, the pressure angle (Pressure Angle, α) is a key parameter, which directly affects the gear contact stress, transmission stability and bearing capacity. ISO 53 The standard specifies the commonly used pressure angle values, where 20 and 25 are the two most common pres
