Math & Numbers
Calculate the ratio, driven speed and chain linear speed of a chain drive. i = z₂/z₁ = n₁/n₂, chain speed v = z₁·p·n₁/60000. Enter the pitch to compute chain speed.
Call this tool from your code in three languages.

POST https://api.elysiatools.com/en/api/tools/chain-sprocket-ratio| Name | Type | Required | Description |
|---|---|---|---|
| z1 | number | Yes | — |
| z2 | number | Yes | — |
| n1 | number | No | Optional. If provided, the driven speed is computed. |
| pitch | number | No | Optional. Combined with n₁ it yields the chain linear speed (m/s). |
