ハースカップリングとカービックカップリングの違い

ハースカップリングとカービックカップリングはどう違う？

「ハースカップリング」の歯形は直線歯形で直線あるいは内側に行くにつれ細くなっていくテーパ形状です。その為、歯当りが小さく面圧は大きくなる場合もあり、半面歯当りのコントロールなどは難しいです。「カービックカップリング」の歯形はコンベックス歯（凸歯）とコンケーブ歯（凹歯）が用いられ結合されます。特徴として、カップリングの中でも締結剛性・割出精度がある事です。「ハースカップリング」よりも高い求心性を持つのが特徴です。高精度に加工するためには専用機が必要ですが工作機械や、専用機・航空機などは、より高精度な位置決め精度が必要な為、多くの工作機械メーカーで用いられております。特に私たちオージックで製造しているカービックカップリングは、工作機械での実績を多く持っておりお客様から大変好評を得ております。ハースカップリングからカービックカップリングへの設計変更案件なども対応しておりますので、ぜひお気軽にお問い合わせください！

Custom Gear Manufacturing Case Study: Production of Standard Carbide Couplings

At Ojik, we can produce standard carbyc couplings that have been discontinued by other companies!

We received a request from a customer to produce a standard Karvic coupling that has been discontinued by another company. After receiving information about the product that the customer was turned down for, we designed and manufactured a product similar to the desired standard item. As a result, we are now able to respond similarly to requests for the production of standard Karvic couplings from other customers as well.

Custom Gear Manufacturing Case Study: Improving the Precision of Mechanisms Using Curvic Couplings

We propose design changes to reduce your assembly labor hours!

The customer has consulted us regarding the coupling they are using in a indexing mechanism for industrial machinery, stating that they are not achieving the desired precision after assembly. At that time, they were using a standard cubic coupling from another company along with other components, but they were having difficulty achieving the necessary assembly precision with those components, leading to issues with rigidity. Therefore, we proposed the integration of the cubic coupling with the other components, made design changes, and successfully achieved the integration. By making it a single unit, we were able to improve rigidity and reduce assembly labor.

Custom Gear Manufacturing Case Study: Turbine Fastening Carbide Coupling

We can process heat-resistant alloys that are difficult to machine, as well as uniquely shaped turbine workpieces!

This is a Karvik coupling used for fastening turbines. It is a heat-resistant alloy that is difficult to process, and due to the turbine's unique irregular shape, chucking was challenging. Additionally, since the turbine operates at a rotational speed of 70,000 to 80,000 RPM, the weight balance between the parts connected via the Karvik coupling is crucial, and the machining was very focused on the pitch accuracy of the teeth. Furthermore, due to the centrifugal force from high speeds, the material deforms, resulting in a special tooth contact for the coupling. In terms of coupling strength, achieving high precision in the machining of the coupling, such as the radius at the tooth base and the runout after coupling connection, was quite difficult. In this case, there were no issues such as tooth surface burning with the difficult-to-machine material during the coupling processing, and we were able to maintain machining accuracy, allowing for smooth delivery without quality control problems. Moreover, we have many examples of Karvik couplings at our company, and we can handle the machining of Karvik couplings located at the edges of impellers and discs. Additionally, we can select optimal tools and set processing conditions for heat-resistant alloys such as titanium and Inconel, so if you have any questions regarding gears, please feel free to contact us from the design stage.

Custom Gear Production Example [Carbide Coupling for Machine Tools]

In the Karvik coupling, we provide custom-made solutions tailored to the shapes designed by our customers!

This is a curvic coupling used in horizontal machining center tables and turret tool holders of lathes. More specifically, it is a product example that is in high demand for index tables. The positioning of the rotation direction and the runout of the end face of the index table are determined by this curvic coupling, making it a component that directly contributes to the machining quality of horizontal machining centers. For such curvic couplings, we provide custom-made solutions tailored to the shapes designed by our customers. Considering that there may be cases where replacement is needed during maintenance, we measure the master coupling owned by the customer, reproduce the same tooth profile, and manufacture it. We first borrow the customer's master coupling and conduct 3D measurements. From there, we create machine settings, perform reproduction and trial machining, and proceed with production. We have also achieved high precision in pitch accuracy while ensuring proper engagement with the master coupling.
