Constant force springs are specialized springs that are used to provide a constant force over a range of motion. This makes them ideal for use in a variety of applications, such as automotive or robotic systems.under we will take a closer look at what constant force springs are and how they can be used. What are constant force springs? A constant force spring is a type of spring that produces a constant force over its entire range of deflection. This type of spring is often used in applications where a stable force is required, such as in the actuation of a valve. Constant force springs don’t have much in common, either in form or function, with standard helically wound springs. For starters, constant force springs are formed from pre-tensioned metal strips, rather than wire. At their most basic level, however, constant force springs do exactly what other springs do. That is, they conform to Hooke’s Law. Hooke’s Law essentially states...

Two aspects to be considered in designing constant force spring
Two aspects to be considered in designing constant force spring
The constant force spring is made of stainless steel strip. The high strength steel strip is shaped by specific spring production equipment. When the external force is straightened, the hair strip will naturally roll back and produce elastic force. However, to achieve our goal, we can return to the designated starting point after displacement.     Constant force spring has the characteristics of maintaining constant force in a long stroke. Its function can be applied to the adjustment of lifting doors and windows, computer monitors and fans, shopping mall display shelves or motor carbon brush motors and other products that require linear motion such as round trip, sliding, stretching, homing, balance or force saving. So how to design the constant force spring in line with product performance ? We generally need to consider from two aspects :     1.

Design and manufacturing method of constant force spring
Design and manufacturing method of constant force spring
 Design and manufacture a complete set of constant force springs for a variety of applications in almost all industries, from medical care to aerospace and general household products. The constant force spring is different from the traditional spiral wound spring. They are made of pre tensioned high-yield metal strips (usually stainless steel) rather than wires. Constant force springs are classified as "tension springs". When winding, the metal strip resists uncoiling with nearly constant resistance. When extended, the internal stress of the metal resists any load force at a nearly constant rate. Once the spring extends to a length of 1.25 times its diameter, it reaches full load and produces a nearly constant force. According to the size of the spring and the load it supports, the fatigue life cycle of the constant force spring is between 2500 and 1000000 times.     Constant force springs are commonly used in automotive engineering, aerospace engineering, medical and retail. Some common applications are:...
Constant Force Springs
Constant Force Springs
The extension type of Constant Force Spring represents the most basic, yet most versatile, type of constant force spring. It is a pre-stressed flat strip of spring material which is formed into virtually constant radius coils around itself or on a drum. When the strip is extended (deflected) the inherent stress resists the loading force, the same as a common extension spring, but at a nearly constant (zero) rate. A constant torque is obtained when the outer end of the spring is attached to another spool and caused to wind in either the reverse or same direction as it is originally wound. The full rated load of the spring is reached after being deflected to a length equal to 1.25 times its diameter. Thereafter, it maintains a relatively constant force regardless of extension length. The load is basically determined by the thickness and width of the material and the diameter of the coil. Qianye Spring  offers a stock of constant force springs in a variety of...
Design of constant force springs
Design of constant force springs
 A constant force spring is a spring that exerts a constant force over its range of motion. That is, it does not obey Hooke's law. Typically, a constant force spring is constructed as a coiled band of spring steel so that the spring relaxes when fully coiled. When it is unrolled, the restoring force comes mainly from the portion of the belt that is close to the roll. Since the geometry of this region remains nearly constant as the spring unfolds, the resultant force is nearly constant.       By creating a spring with a variable pitch, you can make a push-shape spring with a constant velocity. Placing a larger pitch in a larger outer diameter coil and a smaller pitch in a smaller outer diameter coil will force the single spring to fold all coils at the same rate when compressed.       Design of Constant Force Springs: A constant force spring is a coil of prestressed...

 Motor brush spring and wind turbine maintenance
Motor brush spring and wind turbine maintenance

Time:2022-9-14

Research shows that to get the greatest return from turbines, whether onshore or offshore, the bigger the turbine, the better. Wind turbines have proven to produce reliable and pollution-free energy, and as technology innovates, the cost of developing and manufacturing them will only become more affordable.  Motor Brush Materials and Wind Turbine Maintenance     Motor brushes are consumables, which means there is significant wear and tear over time and will need to be replaced. While proper wind turbine operation and maintenance requires moderate wear, excessive wear can create carbon dust in the slip ring cabinet, reducing internal isolation.      Also, a useful tip to keep in mind is that motor brushes that are evenly worn indicate good performance. Since reliability is critical in wind applications that generate electricity for industrial tasks and homes, businesses and schools, it is important to work closely with your engineers and parts manufacturers to determine the best motor brush materials. Two common options include: Copper carbon brushes are very common and affordable. They can be used for up to two years, but due to the high amount of carbon dust, they need a lot of maintenance. On the other hand, silver motor brushes are more expensive, but cleaner, can withstand harsh weather, and can be used for up to five years. Slip ring compatibility and design is another component to consider. Although there is wear, your motor brush must maintain a stable surface finish to avoid overtime affecting the performance of the brush. Due to the high cost of repair or replacement of wind...
 What are Torsion Springs and How Do They Work
What are Torsion Springs and How Do They Work

Time:2023-3-6

Torsion springs are mechanical components that store and release rotational energy. They are used in a wide range of applications, from simple door hinges to complex machinery. Torsion springs work by twisting or rotating around their center axis, generating torque or rotational force.   The basic design of a torsion spring consists of a helical coil of wire with arms extending from each end. The ends of the arms are attached to other components, such as a shaft or a hinge, which creates a rotational force when the spring is twisted. When the torsion spring is rotated, the coils wind up, storing potential energy. The stored energy is then released as the spring unwinds, generating torque in the opposite direction.     The amount of torque generated by a torsion spring depends on several factors, including the wire diameter, coil diameter, number of coils, and the type of material used. Thicker wire diameters and smaller coil diameters will produce stronger torsion springs, while a larger number of coils will produce a weaker torsion spring. Materials commonly used for torsion springs include high-carbon steel, stainless steel, and music wire.   Torsion springs are used in many different industries and applications. They can be found in everything from automotive suspensions and aerospace systems to garage door hinges and mousetraps. Torsion springs are often used in applications where space is limited, as they can generate significant torque in a compact package.   Overall, torsion springs are an essential component in many mechanical systems, providing rotational force and energy storage capabilities. They come in...

Torsion springs: where are they used and why did you choose to utilize them?

Time:2022-12-1

There are many types of springs, but the most common are torsion springs. The design of torsion springs is optimized to maintain maximum rotational pressure between two surfaces, these helical or helical springs are usually adhered to the coils at both suspended ends. These ends are connected to external components, which are then rotated to apply bending stress. Unlike other springs, torsion springs are ideally balanced and able to withstand twisting, giving them a place in many industries. Made of various coated metals such as stainless steel, carbon, titanium, nickel or copper alloys, torsion springs are usually wound around a shaft to further increase its stability. The basic principle of a torsion spring is to retain energy as the spring assembly twists. When this is applied, torque is applied in the opposite direction to the deformation angle. This allows energy to be stored and released when necessary, and the torsion spring also secures the mechanism when necessary.       Torsion springs are used in many applications; especially those using pop-up styles. They are used in various clamps and specific door mechanisms such as those found in CD players. One of the most obvious uses of torsion springs is undoubtedly in a mousetrap, which relies entirely on a centrally located torsion spring. They also sit in the center of traditional clothing clips. They are also used in heavier cases such as garage door balancers or car trunk opening mechanisms. Even in ancient times, primitive torsion springs were used as part of the giant catapults (or trebuchets) that were later used...

Car covers are commonly used automotive protective articles, but the folding and storage of car covers is a troublesome thing. In order to solve this problem, invention lovers have done a lot of useful exploration and put forward many solutions. One kind of scheme is to use power to drive the reel to directly roll up the car cover cloth. Using the reel to directly roll up the car cover cloth can achieve the purpose of rapid retraction of the car cover, but there are the following problems in actual use: first, the winding and friction of the reel when directly rolling up the car cover cloth wear the car cover cloth greatly; second, in order to adapt to the width of the car cover cloth, the width of the car cover retracting device must be close to the width of the car cover cloth. If it is too narrow, it will increase the winding of the car cover cloth, so the shape of the car cover retracting device is larger, It reduces the convenience of use: Third, it may not be able to completely stow the hood cloth.
