Chain Coupling

TransDrive Chain Couplings are constructed using two precision-machined sprockets and a high-quality double-strand roller chain, forming a compact yet powerful coupling solution. Their simple design provides excellent flexibility and a higher torque transmission capacity compared to other couplings of similar size.

These couplings are ideal for applications requiring easy assembly and disassembly, as they allow for quick connection and removal without disturbing surrounding equipment. When used with a protective housing, TransDrive chain couplings offer enhanced safety by containing the moving parts, while also extending service life by shielding the components from dust and debris.

Robust, efficient, and easy to maintain, TransDrive Chain Couplings are a reliable choice for a wide range of industrial power transmission applications.

We supply couplings that are tested for ISO standard.

Components

Straight Bore Sprockets & Duplex Roller Chains

The coupling includes a pair of sprockets, one for each shaft being connected. Chain couplings also include Duplex Roller Chains, which are used to connect the two sprockets.

Lubricated Method			C

Be sure to use the casing with the coupling in the case of lubricant type C. For detail of lubrication types A and B, refer to “Lubrication” section.

Lubrication

There are three methods to lubricate:

Greasing Monthly
Greasing Weekly or fill grease in the attached casing
Fill grease in the attached casing.

Note

When attaching the casing, use high-quality grease because the grease is pressed to the inside wall of the casing due to centrifugal force, deteriorating lubricating ability of the grease. It is recommended to change the grease periodically to maintain high performance and durability of the coupling.

Grease change intervals (with casing attached)
Operating Conditions	First Change	2nd and later changes
Operating at 1/2 max speed or higher	1000 hours	2000 hours
Operating at 1/2 max speed or Lower	2000 Hours	4000 Hours

Allowable errors

x = 2% or less of pitch of roller chain used

n = 1 or less

In case of high speed operation, shaft deviation and misalignment must be 1/2 allowable errors.
