YYC Taiwan Rack and Pinion

Providing high-quality, low-cost herringbone and flat teeth. Supports ultra-high precision and low-cost high-frequency/carburizing hardening. Herringbone rack twist angle: 19°31'42".

- Delivery time: Limited quantity, approximately 4 to 5 weeks!! - Price range: From 20,000 yen / 1,000mm Module 3 / High grade → Quality grade 6 (Cumulative pitch error: 36μm/1000mm) - Manufactured by Taiwan's YYC company - Rack and pinion capable of high-precision positioning Unlike ball screws, it allows for designs without length limitations - Combination of high-precision planetary gear reducer (backlash of 1 minute) and high-precision ground rack & pinion handled by Tomita achieves a maximum cumulative pitch error of 12μm/1000m - For even higher precision positioning, using a pinion-integrated high-precision planetary gear reducer in tandem allows for further reduction in backlash. - Low noise - When using helical gears, the load-carrying capacity increases by about 20% compared to spur gears. ⇒ Becomes one size more compact than conventional modules ⇒ Significant cost benefits - Proposal for long racks Variations of 500, 1000, 1500, 2000mm per unit ⇒ Recommendations for connection numbers ⇒ Improvement of positioning errors

Non-backlash rack and pinion "TCG Series"

The unique mechanism that enables rolling contact achieves high-precision positioning without backlash, agile motion performance, and low wear and low noise.

The "TCG (Trochoidal Cam Gear) Series" is a drive component characterized by non-backlash. We offer a lineup of TCG runners for rack and pinion and TCG rings for ring gear and pinion. This product employs a trochoidal curve in its tooth shape, allowing the pinion teeth that mesh with the gear to rotate freely on rollers, achieving motion transmission through complete rolling. As a result, it enables high-precision positioning with non-backlash characteristics, as well as smooth rotational-linear and rotational-rotational motion, making it a new motion transmission mechanism with low wear that has been successfully used in clean rooms. 【Features】 ■ Non-backlash ■ High-precision positioning ■ Low noise, low vibration, low wear, low dust generation ■ Achieves long lengths and high speeds (TCG runner) ■ Achieves split rings and large diameters (TCG ring) Additionally, as TCG-related products, we offer: - TCG runner in stainless steel specifications 'CRS&CPS' - TCG lubrication supply system 'TLS' that realizes maintenance-free lubrication - Precision ball reducer with roller pinion 'SFP-P' - Precision differential reducer with roller pinion 'NSP'

[Case Study] Improvement of Production Efficiency through High-Speed Conveyance (Gantry Loader)

An example where the improvement in the loader's positioning accuracy led to the prevention of issues such as defects caused by problems with the stopping position.

We would like to introduce a case study of our "TCG Runner." We wanted to improve production efficiency by increasing the transport speed of a gantry loader that uses a rack and pinion on the drive axis. However, we were searching for alternatives because increasing the speed significantly reduced the lifespan of the rack and pinion and also increased noise levels. After implementation, we were able to increase the transport speed while maintaining lifespan and low noise levels. Additionally, wear on the rack and roller pinion was extremely minimal, and even after long-term use, there was no decline in stopping accuracy. Furthermore, the positioning accuracy of the loader improved, which helped prevent issues such as defects caused by problems with stopping positions. 【Features】 ■ Low wear and high durability even at high-speed operation ■ Rolling contact between the rack tooth surface and roller pin prevents noise generation ■ Non-backlash enables high-precision positioning *For more details, please refer to the related links or feel free to contact us.

Non-backlash rack and pinion "TCG"

High-precision positioning with non-backlash; rack and pinion suitable for clean environments with low dust generation and low wear.

The Rack and Pinion "TCG Series" is a mechanical component that achieves high-precision positioning through non-backlash design. Additionally, since the rollers rotate independently, preloading can be applied, allowing for smooth operation even in a backlash-free state. 【Features】 ■ High feed accuracy and high-precision positioning accuracy ■ Low noise, low dust generation, and low wear due to rolling contact ■ No lubrication work required thanks to the TCG lubrication supply system "TLS" ■ Long lengths can be accommodated by connecting racks using extension jigs ■ Capable of high-speed operation of over 180m/min ■ Large diameter, hollow rings of several tens of meters in size can be used *Technical explanations of the product and documents detailing the product lineup can be viewed from the "PDF Download" section. Please feel free to contact us with any inquiries.
