Ametek Hunter Springs – Constant Force Springs
Basic and most versatile constant force extension spring.
Torque spring motor is a prestressed strip of spring material which is formed into a coil and is stored on a small storage drum.
The NEG’ATOR constant torque spring motor is a prestressed strip of spring material which is formed into a coil and is stored on a small storage drum.
The free end is then fastened and backwound onto a larger output drum; this is the “winding” portion of the constant torque spring’s cycle.
When the output drum is released, the spring will return to the storage drum to assume its natural curvature thus rotating the output drum and providing virtually constant torque.
The Material
Hunter Spring constant torque springs are made of type 301 high-yield stainless steel and are supplied in coils for mounting on motor drums.
