Constant force spring for realizing smooth movement of CT scanning table

Hora:2022-9-14

We are familiar with CT scanner. Now when we go to the hospital for examination, we often hear the doctor say "take a film first". This film generally refers to CT. Doing CT is not only for the safety of patients, but also for the safety of doctors. CT is much clearer than X-ray film. At the same time, there are many diseases that cannot be seen on B-ultrasound and can be diagnosed by CT. At present, CT is the most widely used imaging examination under medical treatment and the most valuable examination for clinical information. When you go to take CT, you lie down on the scanning table, and the scanning table will automatically move smoothly and accurately locate the position. Have you ever thought about this problem because you want to relieve tension? The CT scanner table can move smoothly and accurately because of the role of the constant force spring in it. Some little friends may not know what the constant force spring is. When it comes to the spring, everyone must think it is the traditional linear spring. In fact, it is not. Constant force spring is made of stainless steel strip. The high-strength steel strip is shaped through specific spring production equipment. When it is straightened by external force, the spring will naturally roll back and produce elastic force, However, to achieve our goal, we can return to our designated starting point after the shift. The constant force spring can achieve extremely high elastic output in a very small device space. Its function can be applied to products requiring linear motion such...

 Constant Force Springs Design Guide
Constant Force Springs Design Guide

Hora:2022-9-14

There are many mechanical components to choose from for your device or application. If your device requires a spring, consider constant force springs. These are a type of extension spring. They do not obey Hooke’s law, so their force remains constant, even when deflected. Because of their flat force curve, constant force springs are suitable for applications that require a smooth range of motion and a constant load. Learn more about this type of spring to see if it could work in your device or application. Constant Force Spring Benefits There are many benefits of constant force springs that make them suitable for a number of applications: Have small space requirements Provide a smooth range of motion Have no inertia to overcome Mount to existing hardware Produce a counterbalance effect For these reasons, constant force springs are versatile enough to work for a number of applications in which a constant load is required to counterbalance, tension, retract or dispense. This is why they’re frequently used to enhance surgical devices, deploy and retract doors on aircrafts, and counterbalance windows.   Design Considerations If you decide that constant force springs are ideal for your application, here are some considerations to think about in the design phase of your project. Load Conditions Constant force springs produce a force as the material is extended. Constant force springs are rated at a maximum operating length. This means that the maximum travel must be lower than the difference between the spring’s unextended length and maximum safe operating length. Material Another important design consideration is material. 301 stainless steel is commonly used for standard-issue...
 Application of constant force spring in lifting window
Application of constant force spring in lifting window

Hora:2022-9-14

The lifting window is different from the traditional internal opening, external opening and ordinary push-pull mode, but adopts the opening mode of lifting up and down. Because it is mainly popular in North America, it is also called American lifting window. It is one of the two major door and window categories in the world. The lifting window is more compact than the left and right lifting windows, which is determined by the structure of the window. The traditional lifting window is a sash frame structure, that is, when the window sash is opened left and right, it is realized by sliding the lower pulley on the sliding rail of the window frame. However, there is a gap between the pulley and the slide rail, and the smoothness of the opening must be taken into account, which will inevitably lead to the decline of the sealing performance. The lifting window is a frame-encased sash structure. The sash is wrapped in the window frame and runs vertically up and down. Through the multiple seals of high-quality siliconized tops, the sash frame is tightly fitted around it, and the sealing performance is significantly better than that of the left and right lifting windows, second only to Fixed and casement windows.       The advantages of the sliding doors and windows are: 1. The characteristics of large ventilation, the lifting windows can be opened by 2/1, and the air entering the room can be convected. The European-style lifting windows and casement windows basically cannot open more than half of the area. Second, there can be different...
 Do you know what springs are used as stop mechanisms?
Do you know what springs are used as stop mechanisms?

Hora:2022-9-14

We often find that the spring we make is wrongly used as a stop mechanism in the design. This design defect can occur in all types of springs, including constant force spring, constant torque spring and power spring. For example, consider a simple cable extension product in which the spring retracts the cable into the housing. If the spring is completely wound before the cable is fully deployed, the spring will be used as a stop mechanism. This action will damage the function of the spring and components and should be avoided at all costs. Here are some useful tips when considering the stop mechanism. Constant Force Spring Application:  Initial designs often show the inner end of a Constant Force Spring attached to its’ spool. This is not necessary.  If the spool is larger than the natural spring diameter, the spring will automatically fit tightly on the spool.  In the case when a screw is attached to the spool, additional concerns arise.  If the spring is pulled tight on the screw,  a hump will result that will not only make the retraction difficult but will cause a fracture point and reduce life cycles. To avoid this, we recommend that the spool maintain 1-1/2 wraps of spring material at the furthest extension.  If these additional wraps are not practical in the design, another method of stopping the rotation is required. Constant Torque Spring Applications:   This type of motor spring is commonly used to retract a cable or to keep a constant torque rotational force on a spool.  It is extremely important not...

The reason why the world we live in is so orderly is that there are precise links between large and small objects. So many things in life are crucial. Whether they are large or small, they are indispensable to our life, but some small parts in life are unknown, but there are tens of thousands of them. The spring I know is also one of them. It always exists in a position that people can't see and does their own thing silently. Moreover, he exists everywhere in life, even if we don't know it. Today, I will explain the functions of these small springs. Spring is a kind of mechanical part that uses elasticity to work. Generally made of spring steel. Although the spring is small, as a general basic part, it has large quantity, wide range and complex varieties. It is used to control the movement of mechanical parts, mitigate impact or vibration, store energy, measure the size of force, etc. it is widely used in machines and instruments. The application field involves almost all fields of the national economy. Spring plays a big or small role in all articles in our life. It also has different shapes and structures because of different force values. However, according to the force value, people still divide it into three categories: constant force spring, power spring and variable force spring. Its working principle is to use one of its characteristics. It deforms it by applying force and will also try to return to its original state. Let me show you how springs...
