Product Overview of Sprockets

■ Sprockets is a solid or spoked gear that engages with a roller chain to transfer motion or power.
Application of Sprockets: It is widely used in mechanical transmission in chemical industry, textile machinery, food processing, instrumentation,and petroleum
■ Only Sprockets and chains of the same specifications can be used in combination.
This series is ISO 10B Sprockets, and can be used in combination with MISUMI 40B series chain.
■ Do not use it with ISO 10A series chain, which may cause the chain Sprockets mechanism to fail to function properly!
■ Due to process reasons, it is impossible to guarantee the coincidence of the tooth tops of multiple Sprockets. If you need to use the tooth tops in an overlapping manner, please contact us.

Actual Product

Product Feature of Sprockets

■ Compared with gear drive and belt drive, Sprockets chain drive has the following characteristics:
1. Sprockets, Multi-tooth load-bearing, safe and reliable;
2. Sprockets, Flexible transmission, absorbing shock and vibration;
3. Sprockets, Large center distance range, low manufacturing and installation accuracy requirements;
4. Sprockets, Compared with belt transmission, the transmission ratio is more accurate and the transmission efficiency is higher. It is suitable for the harsh environment of high temperature, dust and humidity.

■ Sprockets, chain selection
Misumi’s Sprockets and chain product selection supports the principle of “Nominal Numbering”

Usage Method of Sprockets

How to mount the Sprockets
(A) Axis configuration
■ 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 chain is stretched, the disengagement between the Sprockets 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 chain is stretched, slack as shown in (5) will occur, and
when a small Sprockets 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 Sprockets 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 chain to provide initial tension in advance, it will eliminate vibration and reduce noise during operation.

Example Use of Sprockets

Used for driving power A mechanism that can convert motor power into roller rotation by combining multiple Sprockets and chains

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

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

Precautions of Sprockets

■ Sprockets maintenance
1. Sprockets tightness should be suitable. If it is too tight, it will increase power consumption, and bearing is easy to wear; if it is too loose, the Sprockets is easy to runout and fall off the chain.
The degree of tightness of the Sprockets is: if lifted up or pressed down from the middle of the Sprockets, the center distance between the two Sprockets is about 2%-3%.

2. The Sprockets shall be installed on shaft without swing and skew.
The end faces of the two Sprockets in the same transmission assembly should be in the same plane. When the center distance of the Sprockets is less than 0.5 meters, the deviation can be 1 mm.
When the center distance of the Sprockets is more than 0.5 meters, the deviation can be 2 mm. But there shall be no friction on Sprockets tooth side. Integral offset.
If the offset is too large, chain is prone to fall off and wear is likely to accelerate. When replacing the Sprockets, you must pay attention to check and adjust the offset

3. After the Sprockets is severely worn, the new Sprockets and the new chain should be replaced at the same time to ensure good meshing.
You cannot replace new Sprockets separately. Otherwise, it will cause bad engagement and accelerate the wear of new Sprockets.
If the tooth surface of the Sprockets is worn to a certain degree, it should be turned over in time (the Sprockets used with adjustable surface) to extend the life time.

4. If the new Sprockets is too long or elongated after use, and difficult to adjust, the links can be removed by the case, but the number of the links must be even.
The link should pass through the back of the Sprockets with the lock piece being inserted outside, and the opening of the lock piece should be in the opposite direction of the turning.

5. Lubricating oil should be timely filled when Sprockets are working. Lubricating oil must enter the matching clearance between the roller and the inner sleeve to improve working conditions and reduce wear.

6. The old Sprockets cannot be mixed with some of the new Sprockets, and should be replaced as a complete set, otherwise it is easy to produce impact in the transmission. Separate replacement of Sprockets will increase wear.

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 sprocket 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. After the sprocket is severely worn, the new sprocket and the new chain should be replaced at the same time to ensure good meshing.
Question: I need to use two overlapped sprockets, I want the tooth top direction to be consistent, is it possible?: Answer: Due to process reasons, it is impossible to guarantee the overlapping of the tooth tops of several sprockets. If the tooth tops are required to be overlapped, please contact our company or indicate on the order (the tooth tops need to be overlapped)
Question: The engraving on the sprocket does not match the packaged model, is it shipped wrongly?: Answer: The product model is subject to the label on the shipping bag and the actual size. The engraving is only the factory management number of the sprocket product during processing, and is not directly associated with the product model.
