Product Introduction

parameter for 08B chain sprocket:

Pitch 12.7

Internal width 7.75

Roller 8.51

Teeth NO: 8-125

Material of 08B chain sprocket

The material shall ensure that the gear teeth have sufficient strength and wear resistance. Carbon steel and alloy steel are commonly used, and the tooth surface is subject to heat treatment. During operation, the small sprocket teeth participate in meshing more times than the large sprocket, with serious wear and impact. Therefore, the material of the small 08B chain sprocket should be good and the tooth surface hardness should be high.

In chain drive, because the chain is polygonal on the wheel and rotates with the 08B chain sprocket, the chain speed and transmission ratio change periodically with time, resulting in uneven movement and dynamic load, impact and vibration, which is the inherent characteristic of chain drive. In order to obtain a more stable chain drive, various motion parameters (pitch, number of multiple teeth, limiting the maximum speed of sprocket) shall be reasonably selected in the design.

Although the pitch of 08A sprocket and 08B chain sprocket is 12.7, there are differences between 08A sprocket and 08B sprocket, and they cannot be used in general.

1. The width of inner section is different, and the thickness of 08A (7.85mm) 08B (7.75mm) sprocket is different

2. The outer diameter of rollers is different, and the tooth type of 08A (7.92mm) 08B (8.51mm) sprocket is different

The standard of chain wheel in our country is English unit. There are 3 points, 4 points, 5 points, 6 points, etc., as well as single, double, three, four row wheels, etc. The row spacing of double row, three row and four row is made according to the national standard.

Secondly, there are sprockets with the letters A and B as models, a as chip sprockets, B as bench sprockets, and 1, 2 and 3 in b1-2-3 as single row, double row and three row sprockets respectively. The tooth thickness of sprockets with different fractions is different.

Sprocket is driven by chain, and the model unit is generally British. There are single row, double row and multi row. Suitable for low speed, heavy load and high temperature. Compared with gears, it can be used where the centers of two shafts are far away.

The center of these 08B Chain Sprockets are machined to fit the exact size of the shaft. They are machined to the listed shaft diameter size and can be machined to the maximum shaft diameter size. The teeth are sized to fit metric ISO roller chains. They are made of stainless steel and will not corrode from moisture or frequent washdowns. The extended hub makes these sprockets more stable and durable than those with flat hubs. They conform to the international standard ISO 606 (formerly DIN 8187) for dimensions and materials.
