Introduction of National Standard Sprocket

100B finished bore sprocket ANSI
  1. Overview of GB sprocket GB sprocket is an important element in mechanical transmission, mainly used for transmitting power and torque, composed of sprocket teeth, chain link and chain plate, cooperating with chain to realize transmission. Its standard size parameters are crucial for mechanical design and application.
  2. Sprocket type Ordinary sprocket: used for general transmission. Variable speed sprocket: suitable for speed regulation. Special sprocket: such as serrated sprocket, guide sprocket, etc.
  3. Basic Parameters Number of teeth (Z): affects transmission ratio and speed. Center distance (C): the distance between the centers of sprockets, affecting the design. Diameter of sprocket (D): outer diameter, depending on the number of teeth and chain specifications. Hole diameter (d): diameter of the center hole, used for installation.
  4. Tooth shape and pitch Tooth shape: Generally arc teeth, to ensure good meshing. Pitch (p): distance between neighboring links, sprocket tooth pitch should be matched with the chain.
  5. Material and surface treatment Material: usually carbon steel, stainless steel or alloy steel, depending on the environment. Surface treatment: such as heat treatment and coating to improve wear resistance and corrosion resistance.
  6. Standard and specification Based on GB/T 1243, the standard covers size, material and process requirements. Selection considerations Load capacity: Selection of appropriate number of teeth and materials. Working environment: temperature, humidity, corrosion, etc. Installation method: choose the installation method according to specific needs.
  7. Types National standard sprocket types include: Single-tooth sprocket: suitable for single-stage or simple transmission. Double-tooth sprocket: suitable for multi-stage or medium complexity transmission. Three-tooth sprocket: for complex transmission. Multi-tooth sprocket: suitable for high precision and high torque drives. Eccentric sprocket: for variable speed or variable pitch transmission. Gear sprocket: Combination of sprocket and gear, high precision transmission. Pulley sprocket: used to change the direction of transmission, suitable for a variety of mechanical transmission.
