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.

Pengaturcaraan Dengan Gandingan
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.
Sambungan mekanikal antara dua aci
Terdapat banyak cara untuk mencapai sambungan mekanikal antara dua aci, termasuk penggunaan gandingan. Satu jenis yang biasa ialah gandingan rasuk, yang juga dikenali sebagai gandingan heliks. Ia digunakan untuk penghantaran tork antara dua aci. Sambungan jenis ini menampung ketidaksejajaran paksi, selari dan sudut.
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.
Penggunaan gandingan adalah perkara biasa dalam jentera dan peralatan. Ia membantu menghantar kuasa dari satu aci pemacu ke aci pemacu yang lain, sambil menambah fleksibiliti mekanikal. Ia juga berguna untuk mengurangkan impak dan getaran yang disebabkan oleh ketidaksejajaran. Ia juga melindungi komponen aci pemacu daripada haus dan lusuh.
Gandingan cangkuk berganda boleh digunakan untuk memberikan halaju sudut seragam pada aci yang dipacu. Satu lagi contoh ialah gandingan bersambung berganda. Gandingan bersambung berganda boleh digunakan untuk menyambungkan aci yang tidak bersilang secara langsung. Kuk bersambung berganda boleh digunakan untuk tujuan yang sama.
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.
Fungsi yang mengawal aliran fungsi lain
Salah satu binaan pengaturcaraan paling mudah ialah fungsi yang mengawal aliran fungsi lain. Fungsi boleh mengambil argumen dan mengembalikan nilai yang berbeza, tetapi ia mesti bersedia untuk mengembalikan sebelum ia boleh menghantar nilai tersebut kepada fungsi lain. Untuk melakukan ini, anda boleh menggunakan pernyataan goto dan pernyataan if. Satu lagi cara untuk mengawal aliran adalah dengan menggunakan pernyataan bersyarat.
Kriteria untuk memilih gandingan
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.
Gandingan fleksibel kilasan juga penting untuk dipertimbangkan. Reka bentuknya harus mampu menahan tork yang diperlukan semasa operasi, serta kelajuan yang diperlukan. Gandingan juga harus mempunyai tahap kekakuan kilasan yang tinggi, serta redaman. Tambahan pula, gandingan redaman dapat mengurangkan tenaga yang dibazirkan melalui getaran.
Saiz gandingan juga ditentukan oleh tork. Ramai jurutera menggunakan tork untuk memilih saiz gandingan yang betul, tetapi mereka juga mengambil kira fleksibiliti kilasan dan kekakuan kilasan. Contohnya, aci mungkin boleh mengendalikan tork yang besar tanpa merosakkan gandingan, manakala cakera mungkin tidak boleh mengendalikan tork yang besar.
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.
Terdapat banyak jenis gandingan yang berbeza. Ada yang memerlukan pelinciran tambahan sepanjang hayatnya, manakala yang lain 100% bebas pelinciran. Satu contoh gandingan bebas pelinciran 100% ialah gandingan fleksibel RBI daripada CZPT. Gandingan jenis ini boleh mengurangkan jumlah kos pemilikan anda dengan ketara.
Selain daripada faedah yang dinyatakan di atas, gandingan elastomer adalah berkos rendah dan memerlukan sedikit penyelenggaraan. Walaupun ia selalunya lebih murah daripada gandingan logam, ia juga mempunyai sifat penyerapan hentakan dan peredam getaran yang sangat baik. Walau bagaimanapun, ia mudah terdedah kepada suhu tinggi. Selain itu, ia sukar untuk diseimbangkan sebagai pemasangan, dan mempunyai kapasiti tork beban lampau yang terhad.
