Horizontal Screw Centrifuge Outer Gear Ring

Overview

 

The outer gear ring of the centrifuge is mainly used to transmit the rotational torque of the centrifuge rotor. Its selection is directly related to the safe operation and life of the equipment. The centrifuge uses the principle of centrifugal force to accelerate the sedimentation speed of particles in the liquid through the strong centrifugal force generated by the high-speed rotation of the rotor, thereby achieving the separation of different substances.

 

Material selection

 

The material selection of the centrifuge outer gear ring is crucial to its performance and service life. Common materials include cast steel, stainless steel, alloy steel, etc. These materials have high strength, hardness and wear resistance, and can meet the use requirements of the centrifuge under high-speed rotation and heavy load conditions. In addition, with the advancement of technology and the development of materials science, some new materials such as composite materials and special alloys are gradually being used in the manufacture of centrifuge outer gear rings to improve their comprehensive performance and service life.

 

Introduction to structural features

 

The structural design of the centrifuge outer gear ring usually considers the following aspects:

• Tooth shape design: The design of the tooth shape directly affects the transmission efficiency and stability. Common tooth shapes include straight teeth, helical teeth, arc teeth, etc. Among them, the arc tooth end face gear has higher tooth surface contact strength and tooth root bending strength characteristics, which can more easily meet the performance requirements of high-power drive systems for connecting end teeth. Straight tooth end teeth have the characteristics of large torque transmission, good rigidity, and high assembly efficiency.
• Heat treatment: In order to improve the hardness and wear resistance of the outer gear ring, heat treatment processes such as quenching and tempering are usually performed.
• Surface treatment: In order to further improve the corrosion resistance and service life of the outer gear ring, surface treatment such as carburizing and shot peening can also be performed.
