Torsion springs: where are they used and why did you choose to utilize them?
Torsion springs: where are they used and why did you choose to utilize them?
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.      ...
Analysis on the causes of carbon brush fault of generator set
Analysis on the causes of carbon brush fault of generator set
In recent years, several safety briefings have successively reported shutdown accidents caused by carbon brush or rotor collector ring failure of large generator units, resulting in great economic losses to the enterprise.Carbon brushes are motor brushes. Improper maintenance and use of the carbon brush of the generator set during operation will cause accident load reduction or even shutdown.        Factors leading to carbon brush fault      Electromagnetic factors : when reactive or excitation current is adjusted, the spark of carbon brush has obvious change. When the exciter commutates, the contact between the carbon brush and the commutator is not good, and the contact resistance is too large ; the uneven thickness of the oxide film of the rectifier or slip ring causes the unbalanced distribution of carbon brush current ; or sudden change of load and sudden short circuit lead to abnormal voltage distribution between commutators ; unit overload and imbalance ; carbon brush selection is unreasonable, carbon brush spacing...

Power spring in the design of the car covers
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,...

 Different types of springs and their applications
Different types of springs and their applications

Time:2023-2-6

A spring is a very important mechanical component used in many products to affect motion, improve shock absorption, etc. In other words, rapid prototyping services such as 3D printing and CNC machining can create different types of springs that can be used to influence and manufacture products such as watches and mobile phones. Some of the most widely used products incorporate springs into their designs. This requires knowledge and selection, which requires an understanding of springs and their applications. Therefore, this article discusses springs, their advantages and disadvantages, as well as the different types of springs and their applications. Let's start with spring. A spring is a device that stores energy when a force (from a load) is applied and releases energy when the load is removed. Under normal conditions, regardless of the type of spring used in the product, the spring returns to its original shape when the load is removed. The use of springs in any product is based on Hooke's law. Hooke's Law simply states the relationship between the "force" applied to a spring and its elasticity. Simply put, Hooke's Law states that the force required to compress and stretch a spring is proportional to the displacement of the spring. Different types of springs and their applications Springs are made of different materials, shapes, functions, etc. and thus require a wide variety of applications. Spring is divided into three main classes, each of which has different subclasses. 1. Torsion spring The two ends of the torsion spring are connected to two different components. This separates the two...

 The unique quality of constant force spring makes it a perfect balance for heavy moving parts. If your equipment requires springs, consider constant force springs. This is a kind of tension spring. They do not obey Hooke's law, so their force remains unchanged, even when deflected. Constant force spring can be used in almost all kinds of products. Some of the largest consumers are medical device manufacturers. Machines, dental X-ray equipment - and almost any articulated and heavy equipment - are equipped with constant force springs. Smaller constant force springs for medical devices are also part of syringes and drug injectors. We can also find a large number of constant force springs in daily necessities, such as retractable key chain, retractable dog rope, vacuum cleaner, thread winder, safety belt, window balance system, indoor shutter and monitor lifting and so on. Due to the flat force curve of constant force spring, constant force spring is suitable for applications requiring stable motion range and constant load.

Garage doors use high cycle torsion springs for lifetime use It is important to ensure that the garage doors are in proper working order. Improving the cycle life of garage door torsion springs is an effective way to ensure a longer garage door life. A standard torsion spring has a service life of approximately 10,000 cycles, which equates to approximately 7 years of daily use. Increasing the cycle life of your torsion spring will not only reduce the chance of damage or damage, it will also prevent you from having to replace it sooner than expected. Correct Garage Door Torsion Spring Specifications for Protecting Doors Replacing the torsion spring with the proper size, too big or too small, will balance the door and make it secure again. The door lifts effortlessly and stays securely in place. A garage door opener may also need to be replaced if it is damaged by an oversized or undersized spring. How do I know what size torsion spring I need? This is a question we often hear from our clients, and fortunately, the answer is easy to find. You can use the correct existing spring to size your torsion spring in four easy steps: Find out if the wind from the spring is blowing to the left or to the right.
