1. Standard rebar couplers Introduction
Standard rebar coupler belongs to Rolling technology, it is a parallel-thread mechanical splicing system used for the 16mm to 40mm reinforcing bars mechanical connections. This system is first peeling the rebar rib and then doing thread by cold rolling, this technology can meet with China standard of JGJ107-2571, USA standard of ACI318, UK standard of BS8110, VN standard of TCVN8163, and other international standards. The couplers can be divided into standard couplers with all right-hand thread, and also positional rebar coupler with 1 side left-hand thread another size right-hand thread, also it has transition couplers which 2 sides have different diameters. Also, this coupler has a competitive price over super couplers and is suitable for little lower rebar grades such as HRB400 or HRB500 rebar, it has full sizes from 16mm to 40mm.

برنامهنویسی با کوپلینگها
A coupling is a mechanical device that connects two shafts together and transmits power. Its purpose is to join rotating equipment and allows some degree of end-movement or misalignment. There are many different types of couplings. It’s important to choose the right one for your application.
اتصال مکانیکی بین دو شفت
روشهای زیادی برای اتصال مکانیکی بین دو شفت وجود دارد، از جمله استفاده از کوپلینگ. یکی از انواع رایج، کوپلینگ تیری است که به عنوان کوپلینگ مارپیچی نیز شناخته میشود. این نوع اتصال برای انتقال گشتاور بین دو شفت استفاده میشود. این نوع اتصال، ناهمترازیهای محوری، موازی و زاویهای را در بر میگیرد.
The hubs and shafts of a worm gear are connected together by a coupling. This mechanical connection allows one shaft to turn another without causing a mechanical failure. This type of coupling is made from sliding or rubbing parts to transfer torque. However, the coupling is not designed to withstand jerks, so it isn’t suitable for high-speed applications.
استفاده از کوپلینگ در ماشین آلات و تجهیزات رایج است. این وسیله به انتقال نیرو از یک محور محرک به محور دیگر کمک میکند و در عین حال انعطافپذیری مکانیکی را افزایش میدهد. همچنین برای کاهش ضربه و لرزش ناشی از ناهمراستایی مفید است. همچنین اجزای محور محرک را از سایش و پارگی محافظت میکند.
یک کوپلینگ دو قلابه میتواند برای ایجاد سرعت زاویهای یکنواخت در شفت محرک استفاده شود. مثال دیگر، کوپلینگ دو مفصله است. یک کوپلینگ دو مفصله میتواند برای اتصال شفتهایی که مستقیماً متقاطع نیستند استفاده شود. یوک دو مفصله را میتوان برای همین منظور استفاده کرد.
A shaft coupling is a device that maintains a strong mechanical connection between two shafts. It transfers motion from one shaft to another, at all loads and misalignments. Unlike a conventional linkage, a shaft coupling isn’t designed to allow relative motion between the two shafts. Couplings often serve several purposes in a machine, but their primary use is torque and power transmission.
توابعی که جریان تابع دیگری را کنترل میکنند
یکی از سادهترین ساختارهای برنامهنویسی، تابعی است که جریان یک تابع دیگر را کنترل میکند. یک تابع میتواند یک آرگومان بگیرد و مقدار متفاوتی را برگرداند، اما قبل از اینکه بتواند آن مقدار را به تابع دیگری منتقل کند، باید آماده بازگشت باشد. برای انجام این کار، میتوانید از دستور goto و دستور if استفاده کنید. راه دیگر برای کنترل جریان، استفاده از یک دستور شرطی است.
معیارهای انتخاب کوپلینگ
There are several important factors to consider when choosing the right coupling. One of the most important factors is coupling stiffness, which depends on the material used and the shape. The stiffness of a coupling determines its ability to resist elastic deformation. A stiff coupling is desirable for certain types of applications, but it’s undesirable for others. Stiffness can reduce the performance of a system if there’s too much inertia. To avoid this, ensure that the coupling you choose is within the recommended limits.
The size of a coupling is also important. Different coupling types can accommodate different shaft sizes and shapes. Some couplings have special features, such as braking and shear pin protection. When choosing a coupling, you should also consider the type of driven equipment. If you need to connect a high-torque motor, for example, you’ll want to choose a gear coupling. Likewise, a high-speed machine may require a disc coupling.
Another factor to consider when selecting a coupling is the torque rating. Despite its importance, it’s often underestimated. The torque rating is defined as the torque of the coupling divided by its OD. In some cases, torque may fluctuate during a cycle, requiring a coupling with a higher torque rating.
کوپلینگهای انعطافپذیر پیچشی نیز باید در نظر گرفته شوند. طراحی آنها باید بتواند گشتاور مورد نیاز در حین کار و همچنین سرعت مورد نیاز را تحمل کند. کوپلینگ همچنین باید از درجه بالایی از سختی پیچشی و همچنین میرایی برخوردار باشد. علاوه بر این، یک کوپلینگ میرایی میتواند انرژی تلف شده از طریق ارتعاش را کاهش دهد.
اندازه یک کوپلینگ نیز توسط گشتاور تعیین میشود. بسیاری از مهندسان از گشتاور برای انتخاب اندازه صحیح کوپلینگ استفاده میکنند، اما انعطافپذیری پیچشی و سختی پیچشی را نیز در نظر میگیرند. به عنوان مثال، یک شفت ممکن است بتواند گشتاور زیادی را بدون آسیب رساندن به کوپلینگ تحمل کند، در حالی که یک دیسک ممکن است قادر به تحمل مقادیر زیادی گشتاور نباشد.
Besides torque, another important consideration in coupling selection is the cost. While a coupling may be cheaper, it may be less reliable or easier to maintain. Couplings that are difficult to service may not last as long. They may also require frequent maintenance. If that’s the case, consider purchasing a coupling with a low service factor.
انواع مختلفی از کوپلینگها وجود دارد. برخی از آنها در طول عمر خود به روانکاری اضافی نیاز دارند، در حالی که برخی دیگر نیازی به روانکاری ندارند. نمونهای از کوپلینگهای بدون نیاز به روانکاری 100%، کوپلینگ انعطافپذیر RBI از CZPT است. این نوع کوپلینگ میتواند هزینه کل مالکیت شما را به میزان قابل توجهی کاهش دهد.
علاوه بر مزایای ذکر شده در بالا، کوپلینگهای الاستومری کمهزینه هستند و به نگهداری کمی نیاز دارند. در حالی که اغلب ارزانتر از کوپلینگهای فلزی هستند، خواص جذب ضربه و میرایی ارتعاش بسیار خوبی نیز دارند. با این حال، آنها در برابر دماهای بالا حساس هستند. همچنین، به عنوان یک مجموعه، بالانس کردن آنها دشوار است و ظرفیت گشتاور اضافه بار محدودی دارند.
