HELICAL Couplings from the United States

Spiral's Mechanized Spring is a type of component that processes materials into flexible spiral structures. The key to the widespread use of Mechanized Spring lies in HELI-CAL Flexure, a flexible spiral concept applied in the manufacturing of Spiral Mechanized Spring. Due to the fact that Spiral's springs are machined as a whole according to special design requirements (unlike traditional ones, which assemble several components with different functions centered around the spring together), it provides clearer applications, characteristics, and functions compared to other traditional forms of springs.

In situations where the spring and other components are required to be integrated, special connection methods are required. In situations where the space for using the components is limited, high precision is required. In situations where the spring has a long service life, it is required that the spring does not bend or shift radially during stretching or compression. In situations where the spring does not produce noise during operation, it is required that the spring does not twist during compression. In situations where rapid assembly is required, the spring has a high compression capacity. In situations where the spring has a special appearance or material, it is required that the spring acts as a vibration isolator. In situations where the spring can operate smoothly, it is required that the spring only transmits bending moments, In situations where torque is not transmitted, springs are required to have high safety during use. In situations where overall product costs are reduced, maintenance or frequent replacement is not necessary

Flexible universal jointAs a mechanical connection between two intersecting rotating axes on different straight lines, a universal joint can transmit torque and motion. Hailico's flexible universal joint, as a more advanced and unique universal joint, greatly surpasses the performance of traditional universal joints. For example, in specific situations, it can adapt to a 90 ° angle deviation and compensate for radial and angular deviations. The most commonly used application of the Hailico flexible universal joint is to replace the 90 ° gear steering gear (gear commutator). Due to the high cost of gears and the need for regular lubrication and maintenance, replacing them with Hailico's flexible universal joints can save a lot of costs in procurement and maintenance. 

HELI-CAL A model aluminum alloy material 

Spiral, with over 50 years of design and manufacturing experience, has a wide range of applications for its flexible couplings, from encoders to aerospace fields. Spiral's products are not only economical but also widely used.

It is a fully integrated metal coupling with a spiral shaped slit on a cylindrical material, with no back clearance and zero tolerance, allowing for an eccentricity of 0.25mm and a deviation angle of 5 °. High strength aluminum alloy is used, and the surface treatment is aluminum oxidation treatment, which has good corrosion resistance. Regarding the installation method on the shaft, there are two options: the positioning screw method (ARM model) or the friction based clamping plate method (ACRM model).

HELI-CAL H model stainless steel material

It is a fully integrated metal coupling with a spiral shaped slit on a cylindrical material, with no back clearance and zero tolerance, allowing for an eccentricity of 0.25mm and a deviation angle of 5 °. Using stainless steel, it is not limited by the working atmosphere gas. Regarding the installation method on the shaft, there are two options: the positioning screw method (HRM) or the friction clamp method (HCRM).

HELI-CAL DS model aluminum alloy material

It is a fully integrated metal coupling with two spiral slits on a cylindrical material, which significantly increases the torsional stiffness compared to the HELI-CAL A model with one spiral slit. As it is an integrated structure, there is no zero backlash, and an eccentricity of 0.15mm and a deviation angle of 3 ° are allowed. High strength aluminum alloy is used, and the surface treatment is aluminum oxidation treatment, which has good corrosion resistance. Regarding the installation method on the shaft, two options are available: the positioning screw method (DSR model) or the friction based clamping plate method (DSCR model).
