Tsuntien precision CO.,LTD

Company Introduction

For the past 30 years ,we produce precision Cycloidal reducer only.

In 1990,Jiangsu luole transmission Co., Ltd. (Taiwan Murata Precision Co., Ltd.) ,INC. and focused on the development and manufacture roller reducer. Released the innovative revolution-rotation roller drive mechanism into reducer which is the prototype of ROLADRIVE reducer. The Roladrive reducer was applied successfully to the machine required high torque and low backlash.

In 2011,accompanied with more than 20 years experience manufactured/developed Roladrive reducer. TSUNTIEN released the new generation of product which integrated two kind of technique of planetary and roller type. The new concept reducer:TTRA-E ,TTRV-C,TTRV-E and TTRD-C have been released. It’s the pioneer in Taiwan who develop and do the mass production capacity for RV reducer.

In 2013,TSUNTIEN products successfully apply to the robotic positioner,ATC,tool magazine,tube-bending machine,chemical engineering,automation industry,electronic wafer/inspection equipment,SCARA,high precision 4 axle/6 axle robotic arm …etc.

In 2018,set up the factory in Kunshan.

TSUNTIEN Kunshan Plant has been fully put into production

TSUNTIEN set up a factory in Kunshan, Jiangsu Province in 2018. After nearly one year of preparation, the factory was fully put into production in May 2019. In the past 30 years, the market has changed a lot, but our belief in focusing on precision RV reducers will never be changed!

Recently, Mr. Yao Cuntian, founder and chairman of TSUNTIEN, personally came to the Kunshan factory for technical guidance. Mr. Yao said: “I am very pleased to witness the opening of our Kunshan plant, which will not only help us strengthen the layout of the mainland to meet the growing business needs, but also provide strong support for local customers and business partners. Looking to the future , we will continue to increase investment in the mainland market to achieve sustained and steady growth.“

Mr. Yao personally came to the Kunshan factory for technical guidance.

About Kunshan TSUNTIEN

TSUNTIEN set up a factory in Kunshan, Jiangsu Province in 2018. The process technology of the Kunshan plant was copied from Taiwan TSUNTIEN, and the core personnel were from Taiwan. At present, the supply of core parts is from the same factories with Taiwan, based on Taiwan TSUNTIEN,more advanced equipment from Germany and Japan were bought. In order to better respond to market demand,we will develop new technologies and strengthen our product lineup, improve product quality and flexibility. We adhere to our beliefs and focus on precision reducers to meet new opportunities and challenges.

Mr. Yao, founder of TSUNTIEN

What are the benefits of TSUNTIEN in Kunshan for mainland customers?

First, reduce lead time.

In the past, due to transportation reasons, the lead time was too long. Now TSUNTIEN has set up a factory in the mainland, which can effectively reduce lead time.

Second, the cost is reduced.

Taiwan TSUNTIEN reducers have been shipped from Taiwan in the past, and it is inevitable to declare customs fees and transportation costs. Setting up factories in the mainland can save customs declaration fees and transportation fees. And the saving will be returned to our customers.

Finally, the after-sales service more efficient.

The Kunshan factory will be responsible for the after-sales service, which will make it easier and faster to solve the problems encountered during the use.

Murata Taiwan reducer V.S Planetary reducer

In the usual customer visiting ,we found that most of the customers can’t distinguish.

Murata Taiwan RV reducer and planetary reducer clearly. Therefore, we make the detailed comparison between Murata Taiwan RV reducer and planetary reducer below.

The planetary reducer is operated by sun gear to drive the planet gear and the ring gear to make the speed reduced , so the planetary reducer is the coaxial operation.

The RV roller reducer is operated by internal eccentric bearing to drive the TwinRoller disc and external rollers to make the speed reduced. By the structure comparison , the roller is stronger than gear and without gear-damaged problem.

On the other hand, the shortage of planetary reducer mechanism is one or two teeth engagements which can’t bear bigger torque (gear-damaged problem). The weakness of the planetary reducer : Due to the sun gear of ratio 10 is too small , the strength is not enough and with the gear-damaged problem.

Another one is due to ratio 3 planetary will make the planet gear rotate faster than the sun gear which can cause the speed up and high gear noise.

TSUNTIEN reducer can transfer the significant higher torque , extremely high rigidity , high impact-resistance capacity and multi-teeth meshed characteristic . Due to no gear structure , the noise and gear-damaged problem are no necessary to worry about. TSUNTIEN roller reducer can build the maximum ratio 140 under one stage ( depends on specification ) and ratio 8000 under two stages. With powerful characteristic and advantage on the price and the structure / high precision / multi-teeth contact ( multi-teeth engagement / high load bearing capacity / high torque /low noise /long service life.

The planetary reducer can only build maximum ratio 10 under one stage and two stages or three stages if more than ratio 10 ( As the picture shown on the right ). The precision and the price will also be affected if more than one stage.

Q:If the customer require the reducer with ratio 100 and high torque output , how to make the appropriate selection advise ?

A:Analyse as below :

1.”TSUNTIEN ”roller gear reduction could build ratio 140 under one stage. “one stage will be enough” .

2. Planetary reducer could make ratio 10 under one stage . If customer requires ratio 100 , it have to made up to three stage. The 2 stage is not recommended because ratio 10 is the vulnerable structure ( the concern of sun gear damage ) .

3. Parallel gearbox would be make 5~ 6 stage ( axis ) under ratio 100 ( depends on the dimension ) .

Conclusion: One stage more means “cost increased ”+ ”precision decreased ”+ “efficiency decreased “ + ”space wasting”+ “weight increased”+ “inertia increased”+ “design inconvenient “.

We can summarize the advantage of Murata Taiwan RV reducer compare to planetary reducer :

- Significant higher torque

- Higher torque

- Higher axial and radial load capacity

- Load capacity increased

- Higher reliability

- No gear noise
