Chain with pin gear attachment
- This is a chain for Pin gear drive.
- Instead of a rack and pinion gear, it uses a chain with attachments and a special sprocket.
- Using a chain attachment, it can be wrapped around the inside and outside of the drum with bolts to secure it in place, or installed in a straight line.
- *Please use heat treated bolts for mounting.
- *Special sprocket required.
What is a chain-type pin gear?
-
- In order to achieve linear motion or large-radius rotational motion, a drive such as a chain or gear is used, passing through a reducer from the driving source (motor, etc.).
Chains require a large space, and gears require precision machining, which can lead to problems such as high costs. Pin gears are ideal for such situations.
Instead of a gear drive wheel, a chain with an attachment is wrapped around the outer circumference of the drum to form a wheel, and a specially processed sprocket is used for the pinion gear.
For linear motion, a chain with attachments is used in place of a rack, mounted in a straight line.

Pin gear drive system
There are three types of pin gear drives: linear, internal, and external.
When selecting sprocket specifications
It is necessary to select a sprocket specification that corresponds to the customer's operating environment and chain specifications.
Chains with pin gear attachments engage differently from regular chain winding transmissions, so a dedicated sprocket with a special tooth profile is required.
