Product Overview of Idlers

■Sprocket Idlers is a sprocket with a built-in bearing. Its main function is to change the rotating direction of the driven wheel, tension the chain, adjust the pressure angle and so on.
The Idlers is a part of the gear train that plays a transitional role. It does not change the transmission relationship. It is to make the force of the gear train more reasonable or to adapt to the layout of the entire transmission system.

■Only Idlers sprockets and chains with the same specifications can be used in combination.
This series is ISO standard 06C/ 08A/ (ANSI specifications 35B/40B) sprocket Idlers.
Do not use them with 06B/ 08B series sprockets and chains, which may cause the chain sprocket mechanism to fail to operate normally!

Product Feature of Idlers

■Idlers Sprocket chain drive has the following features compared with gear drive and belt drive:
1. Idlers 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 chain:
1. Connect the motor for transmission 2. Place the workpiece directly or indirectly on the chain for transfer

Example Use of Idlers

Used for driving power of Idlers
A mechanism that can convert motor power into roller rotation by combining multiple Idlers sprockets and chains
Motor roller for chain drive
Used for transporting workpieces of Idlers
A chain conveyor frame with high versatility using flat profiles and chain guides
Chain conveyor
Used for transporting workpieces of Idlers
A mechanism used to mount accessories on the chain, and extract and transport workpieces
Accessory chain transfer

Usage Method of Idlers

How to mount the roller chain
(A) Axis configuration
■Horizontal Idlers
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 chain is stretched, the disengagement between the Idlers 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.
Chain mounting method-horizontal
■Vertical Idlers
If the chain is stretched, slack as shown in (5) will occur, and
when a small Idlers 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 Idlers on the outside or inside as shown in (6).
Chain mounting method-vertical
(B) Deflection Idlers
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
Chain deflection
(C)When the load changes Idlers
If a tension adjuster is mounted on the tension side or slack side of the chain to provide initial tension in advance, it will eliminate vibration and reduce noise during operation.

Frequently asked question (FAQ)

Question: I bought MISUMI chains, but why can't I use them on my original sprocket?
Answer: Please confirm the specifications of the original sprocket and chain. Specification series number may not match. In addition, there are two specifications: A series and B series in China. The two specifications of sprocket chain are not universal.
Question: Does the chain need routine maintenance after installation and use?
Answer: The chain needs regular maintenance after installation and use. These include daily lubricant application, confirmation of chain slack. The quality of lubrication will affect the life of the chain. Especially in recent years, high-speed use has been increasing, so it is necessary to take efficient lubrication methods.
Question: In chain drive, where is the tensioning wheel usually installed?
Answer: Install the tensioning wheel on the inside of the loose edge of the belt close to the large pulley. It is often used when the center distance is not adjustable.
The tensioning wheel is automatically pressed on the outside of the loose side of the belt close to the small wheel by using the suspending weight. It is used for applications where the transmission ratio is large and the center distance is small.
Question: How to use the carrier chain?
Answer: The carrier chain can only be used for transmission, not for scenarios with large load and high positioning accuracy, please be careful!
Question: Can the chain be cut off when it is extended?
Answer: It can be cut off. Our company has simple chain cutter available for selection.
