Tsubaki Advantage
Tsubaki Pin Gear Drive Unit Replaces Gear Rack Systems
Tsubaki manufactures the perfect substitute to gear rack systems. The pin gear drive unit is a combination of a pin-structure wheel/rack and a gear with special tooth profile that allows greater freedom when designing rotating and linear drive units.
Configurations. A pin gear drive unit is a set consisting of pin gear and pin wheel or pin rack. There are two configurations available: Rotational Drive and Linear Drive. The Rotational Drive consists of a pin wheel and pin gear; the pin wheel diameter can be chosen freely. The Linear Drive, on the other hand, consists of a pin rack and pin gear; the pin rack length can also be chosen freely in accordance to customer requirement.
Structure. The pin gear on these drive units feature specially designed teeth with a unique profile that engage continuously and smoothly with the rollers. The teeth are hardened to improve strength and wear resistance. The tooth profile is based on an approximate involute to ensure smooth engagement with the pin wheel or rack, and employs a unique design that further increase strength.
Model. The standard series is made of steel; the S Series, made of stainless steel is also available. The structure for both models are similar. Here are some features and advantages of these pin gear drive units:
- Easy Installation – The units employs a separable segment design for easy installation. It can even be used with rough installation precision.
- Large transmission torque – The pin gear is designed in forgiving modules and good pin wheel or rack balance provides large transmission toque.
- Can be used in large-scale equipment – By increasing the number of segments, the wheel type units can be used in large drive units compatible with large-scale equipment.
- Wide applications – The pin gear drive units are available in steel, stainless steel, and surface-coated models.
Application Examples:
- Environmental sanitation equipment
- Welding Roll over
- Railroad turntable
- Revolving door mechanism
- Casting line
- Rotary kiln
- Drive for large transporter
- Solar tracking system
- Pallet changer for machine tool
- Handling robot
- Pallet pool for machine tool

Pin Gear Drive Selection Procedure
1. Pre-select the pitch circle diameter of the pin gear drive unit
Rotational Operation
- Pre-select the pitch circle diameter of the pin wheel that suits the size of the equipment.
- Find out the reduction gear ratio required, then pre-select the pitch circle diameter of the pin gear.
Linear Operation
Pre-select the pitch circle diameter of the pin gear based on the equipment layout
2. Calculate the correct tangential load (Fw)
Calculate the applied tangential load (Fw) that will act on the pin wheel or rack based on load conditions.
3. Calculate the corrected tangential load (Ft)
To calculate the corrected tangential load (Ft), obtain the service factor (KS, see Table 1) based on operating conditions. Obtain speed factor (KV, see Table 2) based on the tangential speed, and then multiply the product thereof by the applied tangential load (Fw).
Ft = KS x KV x Fw

4. Select the frame number of the pin gear drive unit
Using the allowable tangential load (Fp) of each pin wheel/pin rack frame number and the corrected tangential load (Ft), select the appropriate pin gear drive unit that satisfies the following condition:
Allowable tangential load (Fp) > Corrected tangential load (Ft)
5. Select the model number
Pin Wheels
From the selected frame number and pre-selected pin wheel pitch circle diameter, choose the quantity of rollers of the pin wheel closest to the pitch circle diameter.
Pin Racks
From the selected frame number and total running distance (or total movement distance), calculate the quantity of rack rollers.
Pin Gears
From the selected frame number and pre-selected pin gear pitch circle diameter, choose the model number of the pin gear with the number of teeth closest to the pitch circle diameter.
Note: There are limits to the extent to which numbers of gear teeth can be used. If a gear does not have enough teeth, select a gear with larger number of teeth.
Lubrication
Before operation, coat all peripheral roller surfaces with extreme pressure grease. The interior of pin wheel and pin rack rollers are pre-coated with lubricating grease. Contact Tsubaki if using environments where lubricating grease cannot be used, such as under water, or if using at temperature if 130 degrees Celsius or higher.
