Custom Gear Production Example [Spar Gear for Aircraft]

Custom Gear Production Example [Spar Gear for Aircraft]

We can also manufacture gears for aircraft with high demand specifications.

This is a product example of drive gears (spur gears) used in aircraft AGBs. Our company also manufactures gears for power transmission in transport vehicles such as airplanes and drones, and this particular request had high requirements. In terms of quality control, there are high precision demands unique to aircraft, including issues like tooth surface burning, surface roughness, root radius, and tooth profile correction. We maintain thorough management from processing equipment to inspection devices, including specially calibrated gear measuring machines and surface roughness measuring instruments. Additionally, we carry out work in accordance with customer requirements and JIS standards, including quality records, visual inspection capabilities, and handling of materials. Furthermore, since the management system for aircraft machined parts is also scrutinized, we have obtained JIS Q 9100 certification. By establishing such a rigorous management system, we are confident that we can perform grinding processes that meet the quality criteria requested by our customers. If you are facing issues with high-quality gears, tooth surface accuracy, or machining precision, please contact OJIC, which has a wealth of manufacturing experience.

Custom Gear Production Case Study: Prototype Spur Gear for Drone Drive Unit

Custom Gear Production Case Study: Prototype Spur Gear for Drone Drive Unit

Our company has a specialized team skilled in thin-walled processing.

This is an example of a spur gear used in the drive unit of a drone. It was a case where we were commissioned to manufacture gears as a prototype development product. Since the gears are used in drones, they required a small module and a lightweight blank shape. Additionally, due to the active research and development in the industry, there was a request for short lead times for processing at the time of the order. Our company has a specialized team skilled in thin-walled processing, and we carried out the blank processing in that department. Since these are aircraft-related parts, we requested a cooperating company capable of special handling for heat treatment. Furthermore, due to the complexity of the blank shape, process design was challenging, and we took measures to minimize deformation of the blank shape by setting excess material. As a result, we were able to achieve the thin-walled shape requested at the time of the order, and we managed the special processes such as heat treatment without any issues. Additionally, while chamfering is necessary at each corner for stress dispersion, manual chamfering was required for the tooth parts. To suppress variations in quality from such manual work, we continuously conducted shape measurements and quality checks during processing.

Custom Gear Manufacturing Case Study: Drive Spur Gear Used in Air Conditioning Equipment

Custom Gear Manufacturing Case Study: Drive Spur Gear Used in Air Conditioning Equipment

Proposing changes in heat treatment and material can significantly improve quality management! It also enables the reduction of noise and vibration.

This is a product case of spur gears used as the drive component for air conditioning equipment. Specifically, it was a part of air conditioning equipment used for commercial purposes, such as in offices and restaurants. Since it was equipment used by various companies, minimizing noise was a significant focus in this case. To reduce noise, the machining accuracy of the gears and the fitting accuracy of the shaft were extremely important. By repeatedly discussing the process design, we were able to manufacture the product in the shortest possible time. We performed tooth shape corrections suitable for the operating conditions requested by the customer and designed it to accommodate changes in operating posture. We made various proposals, including changes in heat treatment and material, which ultimately led to a significant improvement in quality management. In fact, we received feedback that noise and vibration were reduced compared to previous suppliers, resulting in long-term adoption of our product.

Custom Gear Manufacturing Case Study: Spur Gear for Precision Reducer for Robots

Custom Gear Manufacturing Case Study: Spur Gear for Precision Reducer for Robots

Ultra-high precision processing is carried out using a gear grinding machine uniquely tuned by OJIC.

This is a spur gear used in precision reducers for robots. The size is φ100, the material is SCM, and it has undergone carburizing and quenching as heat treatment. This case was a request for a prototype. As mentioned earlier, since it is a gear used in precision reducers, the requirements were 1. lightweight, 2. quiet operation, and 3. low vibration. Additionally, the customer desired a high-precision tooth profile correction of ±1 micron. To meet these requirements, technology and know-how to control machine vibrations and temperatures are necessary. Therefore, Oujic performed ultra-high-precision processing using a uniquely tuned gear grinding machine. The high-precision processing, which is difficult for other companies with the same machinery, was supplemented by the skills of our operators. As a result, we were able to manufacture gears that met all of the customer's requirements within a short delivery time. Since this was a project that other companies could not handle, the customer was very satisfied with our technical capabilities. As in this case, our company has many skilled operators with high technical capabilities, making it possible to produce high-precision gears. Please feel free to consult us regarding anything related to gears.

Custom Gear Production Example [Spur Gears for Machine Tools]

Custom Gear Production Example [Spur Gears for Machine Tools]

Utilizing the LNS (Low Noise Shift Grinding) manufactured by Ricehower, we produce tooth surface profiles suitable for high-speed rotation.

This is a spur gear for machine tools. The size is φ150, the material is SCM, and it has undergone carburizing hardening as a heat treatment. This product is used in the spindle of machine tools, with a maximum rotational speed of 20,000 rpm. By utilizing the LNS (Low Noise Shift Grinding) from Reishauer, we manufacture tooth surface profiles that can handle high-speed rotation. Furthermore, by continuously processing the tooth surface with a screw-shaped grinding wheel, we achieve ultra-high precision machining with pitch accuracy of several micrometers. Typically, the verification of surface profile effects is conducted by the end users, but this can sometimes take a considerable amount of time. At Oujic, we possess the latest gear measuring machines and analysis software capable of measuring the surface profile of our products. By measuring the surface profile in the processing area, we can shorten the prototype period.
