The manufacturing site of the first examination, inspection and final inspection, sampling according to the requirements of some projects, judging the quality change trend;
found abnormal phenomenon of manufacturing, and supervise the production department to improve, eliminate the abnormal phenomenon or state.
5. FQC(Final QC)
After the manufacturing department will complete the product, stand in the customer’s position on the finished product quality verification, in order to ensure the quality of
customer expectations and needs.
6. OQC(Outgoing QC)
After the product sample inspection to determine the qualified, allowing storage, but when the finished product from the warehouse before the formal delivery of the goods, there is a check, this is called the shipment inspection.Check content:In the warehouse storage and transfer status to confirm, while confirming the delivery of the
product is a product inspection to determine the qualified products.
7. Certification.

Sifat Penguncian Otomatis pada Kotak Gigi Cacing
Ya, gearbox cacing memiliki sifat penguncian otomatis, yang dapat menguntungkan dalam aplikasi tertentu. Penguncian otomatis mengacu pada kemampuan suatu mekanisme untuk mencegah transmisi gerakan dari poros keluaran kembali ke poros masukan ketika sistem dalam keadaan diam. Gearbox cacing secara inheren memiliki sifat penguncian otomatis karena desain unik dari roda gigi cacing dan roda cacing.
Perilaku penguncian otomatis muncul dari sudut ulir pada poros cacing. Pada gearbox cacing yang dirancang dengan benar, sudut ulir cacing sedemikian rupa sehingga menciptakan keuntungan mekanis yang menahan gerakan balik. Ketika gearbox tidak digerakkan secara aktif, gesekan antara ulir cacing dan gigi roda cacing menciptakan efek penguncian.
This self-locking feature makes worm gearboxes particularly useful in applications where holding a load in position without external power is necessary. For instance, they are commonly used in situations where there’s a need to prevent a mechanism from backdriving, such as in conveyor systems, hoists, and jacks.
However, it’s important to note that while self-locking properties can be beneficial, they also introduce some challenges. The high friction between the worm gear and worm wheel during self-locking can lead to higher wear and heat generation. Additionally, the self-locking effect can reduce the efficiency of the gearbox when it’s actively transmitting motion.
When considering the use of a worm gearbox for a specific application, it’s crucial to carefully analyze the balance between self-locking capabilities and other performance factors to ensure optimal operation.
Bahan-bahan yang Digunakan untuk Roda Gigi Cacing
Roda gigi cacing diproduksi menggunakan berbagai macam material untuk memenuhi berbagai kebutuhan aplikasi. Beberapa material yang umum digunakan untuk roda gigi cacing meliputi:
- Baja: Baja merupakan pilihan populer untuk roda gigi cacing karena kekuatan, daya tahan, dan ketahanan ausnya. Baja mampu menahan beban berat dan sering digunakan dalam aplikasi industri.
- Perunggu: Perunggu menawarkan pelumasan yang baik dan umumnya digunakan untuk komponen roda gigi cacing (worm gear). Material ini memberikan ketahanan aus yang efektif dan bekerja dengan baik dalam aplikasi yang membutuhkan pengoperasian yang senyap.
- Besi cor: Cast iron is known for its high strength and durability. It’s often used for worm gears in applications where shock loads or heavy-duty conditions are expected.
- Aluminium: Roda gigi cacing aluminium ringan dan tahan korosi, sehingga cocok untuk aplikasi di mana pengurangan bobot menjadi hal penting.
- Plastik: Beberapa roda gigi cacing terbuat dari bahan plastik seperti nilon atau asetal. Bahan-bahan ini sering dipilih karena sifat pelumasannya sendiri dan pengoperasiannya yang senyap.
- Bahan Komposit: Material komposit dapat menawarkan kombinasi sifat-sifat seperti konstruksi ringan dan ketahanan terhadap korosi. Material ini dapat cocok untuk aplikasi tertentu.
The choice of material depends on factors such as the application’s load, speed, operating environment, and required performance characteristics. It’s important to consider these factors when selecting the appropriate material for worm gears to ensure optimal performance and longevity.
Mencegah Backlash pada Gearbox Cacing
Kelonggaran (backlash) pada gearbox cacing dapat menyebabkan penurunan akurasi, kesalahan posisi, dan penurunan efisiensi secara keseluruhan. Berikut adalah langkah-langkah untuk mencegah atau meminimalkan kelonggaran:
- Komponen Berkualitas Tinggi: Gunakan roda gigi cacing dan roda cacing berkualitas tinggi dengan toleransi manufaktur yang ketat. Komponen presisi akan membantu mengurangi celah (backlash).
- Penyusunan Jaringan yang Tepat: Pastikan roda gigi cacing dan roda gigi cacing sejajar dan terhubung dengan benar. Penyambungan yang tidak tepat dapat menyebabkan peningkatan celah (backlash).
- Pramuat: Memberikan sedikit beban awal pada roda gigi cacing dapat membantu mengurangi celah balik. Namun, beban awal yang berlebihan dapat meningkatkan gesekan dan keausan.
- Mekanisme Anti-Reaksi Balik: Pertimbangkan untuk menggunakan mekanisme anti-backlash, seperti sistem pegas atau shim yang dapat disetel, untuk mengkompensasi backlash yang ada.
- Pelumasan: Pelumasan yang tepat dapat mengurangi gesekan dan berperan dalam meminimalkan celah balik. Gunakan pelumas yang memberikan kekuatan lapisan film yang baik dan mengurangi keausan.
- Pemeliharaan: Lakukan inspeksi dan perawatan rutin pada gearbox untuk mengidentifikasi dan mengatasi setiap perubahan pada celah (backlash) seiring waktu.
Penting untuk mencapai keseimbangan antara mengurangi celah (backlash) dan menjaga kelancaran operasi. Berkonsultasi dengan ahli gearbox dan mengikuti panduan pabrikan akan membantu Anda mengoptimalkan kinerja gearbox cacing Anda sekaligus meminimalkan celah.
