We will introduce the benefits of utilizing our "Precision Reduction Gear RV" with real examples. One customer was experiencing frequent failures due to a weak rotation axis for the arm, making the entire device fragile and posing challenges for ensuring worker safety. In response, they directly consulted us to see if we could enhance the strength of the rotation axis with our high-rigidity product. After carefully listening to the current situation, we proposed a reduction gear suitable for the required precision. This contributed to slimming down the main body of the device and helped expand the operator's working area and improve safety. 【Case Summary】 ■ Issues - The rotation axis for the arm is weak, leading to frequent failures. - The entire device is fragile, making it difficult to ensure worker safety. ■ Results - Made significant contributions to slimming down the main body of the device. - Helped expand the operator's working area and improve safety. *For more details, please refer to the PDF document or feel free to contact us.

We will introduce the benefits of utilizing our "Precision Reduction Gear RV" with real examples. One customer was dissatisfied with the reduction gear incorporated into their machine tool equipment. Due to the low rigidity of the reduction gear, equipment malfunctions occurred frequently. As a result, maintenance was required each time a malfunction occurred, leading to an increase in the workload for the operators. Therefore, they introduced our "Gear Head RD2 Series RDS." After the introduction of this product, the frequency of failures significantly decreased, which also contributed to an improvement in the durability of the equipment itself. They successfully reduced maintenance workload drastically. [Challenges] - Frequent equipment malfunctions due to the low rigidity of the reduction gear. - Maintenance was required each time a malfunction occurred, increasing the workload for operators. - Generally, increasing the rigidity of the reduction gear would also increase the size of the reduction gear itself, but since the size of the machine tool cannot be changed, replacement of the reduction gear was not possible. *For more details, please refer to the PDF document or feel free to contact us.

We will introduce the benefits of utilizing our "Precision Reduction Gear RV" with real examples. One customer had implemented a robot travel axis that could handle multiple processing devices with a single robot, but they were struggling with the instability of the travel axis's operation, which caused variability in the robot's movement. At that time, they became interested in our product, which is a gear head product combined with the "motor connection part," and decided to adopt the "GH series." The matching with the motor they were using was smooth, and thanks to the high positioning performance, the variability in the robot's travel was greatly improved. [Challenges] ■ They had introduced a robot travel axis that could handle multiple processing devices with a single robot, but the operation of the travel axis was unstable, leading to variability in the robot's movement. ■ They were also considering replacing the reduction gear for improvement, but it was quite a challenge to investigate the matching with the motor they were using. *For more details, please refer to the PDF document or feel free to contact us.

Nabtesco is a publicly traded company on the Tokyo Stock Exchange Prime, born from two long-established manufacturers. Our strength lies in our technology called "motion control," which precisely manipulates movement. For example, we provide "automatic doors" that safely open and close, and "hydraulic equipment" that supports the operation of power shovels. In addition to our existing factories in Tsu City (Japan) and Changzhou City (China), we acquired land in Hamamatsu City in 2020. We are steadily preparing to expand our production base for precision reduction gears. To ensure we can always provide suitable precision reduction gears, we will continue to enhance our production system and product lineup. [Our Features] - A publicly traded company on the Tokyo Stock Exchange Prime, born from two long-established manufacturers - Our precision reduction gears excel in "balancing high torque and compactness" - We propose reduction gears of appropriate sizes, considering the necessary specifications for equipment - Our products are being adopted in various industries, including automotive manufacturing, logistics, and healthcare *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce how the precision control reduction gear 'Precision Reduction Gear RV' handled by Nabtesco is active in various machines and equipment. For example, in industrial robots that skillfully weld car bodies while sparking, our precision reduction gear is used in their joint parts. By adjusting the output from the motor and accurately transmitting it to the arm, our product enables the robot's intricate and powerful movements. Additionally, it is active in various scenarios such as the "wheels" of unmanned transport vehicles, the "opening and closing axis" of iron doors, and the "base" of parabolic antennas. 【Reduction Gears Active in Factories】 ■ "Arms" of automotive welding robots ■ "Drive units" of machining centers ■ "Wheels" of unmanned transport vehicles *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the features of our precision reduction gear series, "Precision Reduction Gear RV." The strength of a reduction gear varies depending on the structure of its gears. If the structure of the reduction gear is weak, it can lead to the fragility of the machines and equipment it is incorporated into. Therefore, our product employs a special gear called a trochoidal gear to enhance strength. Furthermore, by firmly supporting these gears with high-rigidity components, we have dramatically increased rigidity, resulting in a precision reduction gear that is strong against loads and impacts. [Features] ■ High Precision: Reduces the "gap" in gears, achieving smooth and accurate movement. ■ High Rigidity: Increases the number of "engaged teeth" in the gears to enhance strength. ■ High Torque & Compact: Maintains a small size while achieving high output. *For more details, please refer to the PDF materials or feel free to contact us.

A "reducer" is a device that lowers the rotational speed of a motor using gears to obtain high torque. Our company began production of the "Precision Reducer RV" in 1986. At that time, industrial robots faced various challenges, such as "gears used in joints colliding and breaking" and "excessive vibrations." These issues were affecting productivity and quality assurance in many factories. Listening to our customers' voices, we developed the precision reducer to address these challenges. After thorough consideration of how to solve these problems, we arrived at the reducer designed to move strongly and accurately. Now and in the future, Nabtesco will continue to face our customers' needs and evolve our reducer products to solve their concerns. *For more details, please refer to the PDF document or feel free to contact us.
