Pin gear drive Unit
- Proposing cost reduction for rotary and linear drives
- Pin gear drive is a new drive unit that replaces gears and racks.
- The combination of a pin-mechanical wheel/rack and a special tooth gear greatly expands the design freedom of the rotary and linear drive parts.
- *Easy installation: The split segment system makes installation easy. It can also be used with rough installation accuracy.
- *Large transmission torque: The pin gear is designed with a generous module, and the good balance with the pin wheel and rack allows for large transmission torque.
- *Can be used in large equipment: By increasing the number of segments, the wheel type can be used in large drive equipment.
- * A lineup of sizes ideal for large equipment in the steel industry, etc.: Achieves cost and tangential force that surpasses large gears.
Catalogs and Instruction Manuals
composition
Pin gear drive unit is a drive unit that comes with a pin rack (or pin wheel) that meshes with a pin gear.
Features
Easy to install and allows for rough installation.
- - All pins on the pin racks and pin wheels are Hollow Pins for installation, so installation can be easily done using these holes.
Combining segmented units can accommodate large machines.
- - In the case of racks, by aligning the joint surfaces, the pitch intervals between units can be maintained and they can be joined, enabling long linear drives.
- - Pinwheels for large machines are assembled in segments, so by combining segments, large diameter pinwheels can be accommodated.
Compared to the chain system, the transmission force is greater and the size can be reduced.
Structure
The pin gear has a special tooth profile that meshes smoothly and continuously with the roller.
The teeth are hardened to improve strength and abrasion resistance.
Pin gear dedicated tooth profile
The pin gear tooth profile is based on an approximate involute curve, which enables smooth engagement with the pin rack/wheel, while also using a Tsubaki original tooth profile for further strength.

Electroless nickel plating specifications
Electroless nickel plating provides a lineup of specifications that achieve excellent wear resistance and corrosion resistance.
This specification ensures effective coating with a uniform surface treatment.
- Examples of use: transport machinery, machine tools, etc.
- Users can select the same size as they would with the standard series since the allowable tangential loads are the same.
-This product is made to order.
Highly rust-resistant
We offer a lineup of highly rust-resistant specifications that have been enhanced by special surface treatment.
Each part is treated with appropriate rust prevention, providing strong rust prevention in harsh corrosive environments such as outdoors, near water, and in coastal areas.
- Example applications: multi-story parking lots, large transport vehicles, casting lines, water gates, etc.
- Users can select the same size as they would with the standard series since the allowable tangential loads are the same.
- This product is made to order.
Flexible Type
The lineup now includes a flexible type with a wider center distance tolerance and a wider gap between the pin rack/pin wheel and pin gear.
It is effective not only for equipment that requires strict installation precision, but also when the installation position changes during operation due to thermal expansion, etc.
- Examples of use: kiln dryers and civil engineering machinery
- Allowable tangential load is lower than standard series. Refer to the Leafletfor selection.
-This product is made to order.
Special backlash specification (different from the standard allowable tangential load)
-Large backlash specification
Increasing the backlash allows for easy installation.
-Small backlash specification
Backlash can be reduced (2/3 of the standard backlash, compatible frame numbers: PDU020 to PDU120).
Lubrication
Before operation, apply extreme pressure grease to the outer surfaces of all rollers. The inner surfaces of the rollers on the pin wheel or pin rack are pre-lubricated with grease.
Please contact us if you plan to use the product in an environment where lubricating grease cannot be used, such as underwater use, or in a high-temperature environment of 130°C or higher.
Installation Method
Pinwheel, pin rack flat type
A hollow pin is used, so the hole can be used to secure the side to the mating device with a bolt.
When installing, positioning can be done by providing a stopper or guide on the surface with the convex part.
Pin rack angle type
The angled linear rack can be fixed to the mating device using the bolt fastening holes on the leg surface.
