What is a duplex gear, what are its application characteristics and how to process it?

XNUMX. Duplex gear:

Duplex gears are two coaxially rotatinggear(Generally the modulus is the same) It is made into one-piece type, generally used for gear shaping. According to the accuracy requirements, choose fine rolling or gear grinding. It is generally used to change the rotation speed or speed of the output shaft. It is used for the transmission mechanism to make the mechanism compact.This product is called a slip gear in the gear train (transmission).

Duplex gears are generally divided into two parts: ring gear and wheel body. According to the structural shape of the product wheel body, it is divided into disc gears. There are two ring gears. There are splines.

Gear transmission is widely used in modern machinery and equipment, and its function is to transmit movement and power according to a prescribed speed ratio.In the gearbox, there is only one rotation speed or speed without slip gears, and multiple rotation speeds or speeds if there are.

XNUMX. Application characteristics of double gears:

Double gear is a gearbox of some mechanical equipment, through the combination of operating mechanism, sliding gear, so as to achieve speed change, mainly used in automobile gearbox, machine tool reducer headstock and other mechanical equipment fields.

XNUMX. Duplex gear processing:

Gear processingIt is necessary to ensure the regularity of shape, coaxiality, dimensional accuracy and shape and position accuracy, etc. Processing process (for reference): Forging, normalizing-rough turning outer circle and end face-drawn spline hole-deburring-outside fine turning Round and end face-inspection-gear hobbing-gear shaping-chamfering-deburring-gear shaving-high-frequency hardening of the tooth-pushing hole-honing-general inspection.
