Torsion spring design - prototyping - moment calculation - lifespan calculation

We will redesign the improved version of the spring with insufficient strength.

The spring in the photo is a torsion spring designed and prototyped by our company. We received the actual spring because it was reported to be deformed during use. After discussing the situation and calculating its lifespan, we found that its strength was insufficient for the stress (load) during use, so we proceeded with redesigning and prototyping. The material used is "Piano Wire Type A, SWP-A." We selected specifications to improve durability without changing the force (moment) when twisted. (Surface treatment has been applied for storage as a sample.) Our company handles the design and prototyping of torsion springs. If you provide us with general conditions such as the space for the spring and the desired force, we will propose the optimal specifications and create a prototype. Our technical staff will respond carefully, so please feel free to consult us. Tsuruoka Spring Co., Ltd.

Torsion spring design - prototyping - load calculation - lifespan calculation

If you provide us with your desired design specifications, we will design and prototype the torsion spring.

The photo shows a torsion spring designed and prototyped by our company. The material is "spring stainless steel wire, SUS304-WPB," with a wire diameter of Φ0.35. We selected specifications that meet the design conditions specified by the customer: 1) coil inner diameter, 2) load at the maximum angle during installation, and 3) a durability of over 100,000 cycles. Our company handles the design and prototyping of torsion springs. If you provide us with your desired design conditions (even if they are rough), we will propose the optimal specifications. We encourage first-time customers to consult with us without hesitation. In fact, most of our customers who reach out to us have not had any previous transactions with us. We look forward to your inquiries. Tsuruoka Spring Co., Ltd. Technical Contact: Ujiie Phone: 0235-22-0407 FAX: 0235-22-0546 Email: web@tohj.com We also support web conferencing.

Tension spring design - prototype - hook strength calculation - lifespan calculation

When calculating the lifespan of a tension spring, we evaluate not only the strength of the body but also that of the hook.

The tension spring in the photo was designed and prototyped by our company at the request of the customer. The design conditions were the coil outer diameter (+0) and the load from installation to maximum. Additionally, we have ensured that the specification meets the durability requirement of over 1 million cycles. When calculating the lifespan of the tension spring, we evaluate not only the body but also the strength of the hooks at both ends. We chose a "round hook" shape, which is resistant to breakage and deformation. Our company accepts design and prototyping of tension springs. If you provide us with the general specifications (design conditions), we will propose and produce the optimal specifications and prototypes. Please feel free to leave the lifespan calculations to us. If you have any concerns, please do not hesitate to consult us. Tsurugaoka Spring Co., Ltd.
