Product Overview of Chains

■The Chains is a flexible component composed of inner Chains plates, sleeves, rollers, pins, outer Chains plates and other matched combination parts. All Chains used on machinery, mechanisms and machines are referred to as industrial Chains. The roller part of the Chains meshes with the tooth part of the sprocket and transmits power as tension.

■Only sprockets and Chains with the same specifications can be used in combination.
This series is ISO Standard 20B roller Chains, and can be used in combination with our 20B series sprocket. Do not use it with American Standard or Japanese Standard 20A series sprocket, which may cause the chain sprocket mechanism to fail to function properly!

Specifications Overview of Chains

■ Sprocket, Chains selection
This series is ISO Standard 20B roller Chains, and can be used in combination with our 20B series sprocket. Do not use it with Japanese Standard or American Standard sprocket, which may cause the Chains sprocket mechanism to fail to function properly!

Chain 20B Specifications Overview

Product Feature of Chains

■Sprocket Chains drive has the following features compared with gear drive and belt drive:
1. Multi-tooth load bearing, safe and reliable;
2. Flexible transmission, absorbing shock and vibration;
3. Large center distance range, low manufacturing and mounting accuracy requirements;
4. Compared with belt drive, the transmission ratio is accurate and the transmission efficiency is higher, suitable for high temperature.

■Two main purposes of the Chains:
1. Connect the motor for transmission 2. Place the workpiece directly or indirectly on the Chains for transfer

Example Use of Chains

Used for driving power of Chains
A mechanism that can convert motor power into roller rotation by combining multiple sprockets and Chains

Used for transporting workpieces of Chains
A chain conveyor frame with high versatility using flat profiles and Chains guides

Used for transporting workpieces of Chains
A mechanism used to mount accessories on the Chains, and extract and transport workpieces

Precautions of Chains

This series is ISO Standard 20B roller chain, and can be used in combination with our 20B series sprocket. Do not use it with American Standard or Japanese Standard 20A series sprocket, which may cause the Chains sprocket mechanism to fail to function properly!

If you need to cut the chain by yourself, please confirm whether the Chains link to be cut is an inner link or an outer link. If it is a single section after being cut off, it may need to be used with an offset link head.

Usage Method of Chains

How to mount the roller Chains

(A) Axis configuration of Chains
■Horizontal
Even when the two axes are arranged horizontally, the rotation direction of the axis must be considered.
The examples (2) and (3) in the figure show that when the Chains is stretched, the disengagement between the sprocket teeth and the chain is not smooth and may bite.
In particular, the upper and lower chains in (3) will contact each other, so an idler is required.

■Vertical
If the Chains is stretched, slack as shown in (5) will occur, and
when a small sprocket is used on the lower side, the chain may fall off. Therefore, please use it at an angle of 60 or less as shown in (4).
When it is necessary to use it vertically due to the mechanism or space, it is recommended to put the large sprocket on the lower side, and
use the idler on the outside or inside as shown in (6).

(B) Deflection
Deflection is generally about 4% of the shaft spacing, and about 2% in the following cases.
a. Vertical transmission or close to vertical transmission
b. Shaft spacing is more than 1m
c. When frequent heavy load starting and stopping are required
d. When reverse rotation is required

(C)When the load changes
If a tension adjuster is mounted on the tension side or slack side of the Chains to provide initial tension in advance, it will eliminate vibration and reduce noise during operation.
