The blank of precision gear is mainly determined by the factors of gear material, structure, shape, size and specification, service conditions and production batch. The commonly used gear materials are carbon steel, such as 15 steel and 45 steel; Alloy structural steel usually adopts high-speed, high force and high-precision gears.

Precision gear transmission mainly produces transmission power through the meshing of two gears. Precision gear transmission can be divided into parallel shaft spur gear transmission, cross shaft helical gear transmission and cross shaft helical gear transmission. The characteristics of precision gear transmission are compact structure, high efficiency and long service life.

 The machining surface of precision gear is divided into tooth surface and gear datum surface. The gear reference plane mainly includes a reference hole with a perforated gear, an installation end face for cutting teeth, and teeth for measuring the blank position or tooth thickness. Top cylindrical surface. The components of gear transmission usually have complex geometry and high speed and efficiency requirements, and may encounter high working temperature and harsh load, which requires the components to be more durable. Precision technology solves these problems by reducing friction, prolonging component life and improving fuel efficiency; This process can form smooth and micro textured surfaces, so as to improve oil retention and metallurgical safety.

The above is an introduction to the blanks of high-precision gears and gear transmission. Those who need high-precision gears are welcome to consult IHF Hefa gear manufacturers.
