Abstract

Gear merupakan suatu komponen mekanik yang digunakan untuk mentransmisikan daya dalam bentuk putaran. Penggunaan gear dalam berbagai macam aplikasi saat ini menggunakan mechanical gear. Proses transmisi daya terjadi dengan adanya kontak antar gigi yang memiliki beberapa kerugian, di antaranya menyebabkan getaran yang besar pada mesin, kebisingan, dan membutuhkan perawatan yang sulit karena terjadi keausan pada roda gigi. Mechanical gear dapat diganti dengan magnetic gear. Salah satu jenis magnetic gear adalah tipe spur gear yang terdiri dari dua macam yaitu tipe external dan internal. Selain mode transmisi dayanya, magnetic spur gear juga dibedakan berdasarkan susunan pole pada gearnya, yaitu tipe radial dan aksial. Pada internal magnetic spur gear tipe radial dapat dihasilkan torsi yang besar, tapi assembly-nya pada gear box kurang kuat dan tidak dapat langsung dihubungkan dengan poros, sehingga daya tidak dapat ditransmisikan secara maksimal dan gear box rentan mengalami kerusakan diakibatkan besarnya torsi yang dihasilkan. Sedangkan pada internal magnetic spur gear tipe aksial, torsi yang dihasilkan lebih kecil daripada tipe radial, akan tetapi memiliki kelebihan konstruksi, yaitu dapat langsung dihubungkan dengan poros, sehingga daya dapat ditransmisikan secara maksimal. Oleh karena itu, dilakukan optimasi dimensi magnet permanen pada internal magnetic spur gear tipe aksial sehingga dihasilkan torsi yang besar sebagaimana tipe radial, dengan assembly yang lebih kuat. Penelitian ini terdiri dari proses pemodelan internal magnetic spur gear tipe aksial, kemudian dilakukan simulasi pada software berbasis finite element analysis dengan mode transient yang meliputi assembly komponen magnetic gear, pemilihan material, pengaturan region, pengaturan meshing, pengaturan boundary dan excitation, kemudian dilakukan penentuan gear yang bergerak dengan membuat band, model set up dengan mengatur gear agar berputar dengan putaran 20 rpm, validate, analysis set up, dan post-processing untuk analisa hasil. Simulasi dilakukan dengan variasi dimensi magnet permanen pada arah radial, axial, dan tangensial. Berdasarkan hasil simulasi pada internal magnetic spur gear tipe axial, ukuran dimensi arah radial mempengaruhi kenaikan torsi sebesar 11,9 % setiap bertambah 10 mm, ukuran dimensi arah aksial mempengaruhi kenaikan torsi sebesar 62,05 % setiap bertambah 10 mm, dan ukuran dimensi arah tangensial tidak mempengaruhi kenaikan torsi secara signifikan.

Gear is a mechanical component used to transmit power in the form of rotation. The use of gear in a variety of applications today uses mechanical gear. The power transmission process occurs with the presence of contact between teeth which has several disadvantages, including causing large vibrations in the engine, noise, and requiring difficult maintenance due to wear on the gears. The mechanical gears can be replaced with magnetic gears. Spur gear is a type of magnetic gear consisting of two types, namely external and internal spur gear. In addition to its power transmission mode, magnetic spur gear is also distinguished based on the pole arrangement in the gear, namely the radial and axial types. In the internal magnetic spur gear, the radial type gear can produce a large torque, but the assembly in the gear box is less strong and cannot be directly connected to the shaft, so that the power cannot be transmitted maximally and the gear box is susceptible to damage due to the large torque produced. Whereas in the axial internal magnetic spur gear, the torque produced is smaller than the radial type, but it has the advantage of construction, which can be directly connected to the shaft, so that the power can be transmitted maximally. Therefore, optimization of the permanent magnet dimensions of the axial type internal magnetic spur gear is carried out so that large torque can be produced as the radial type, with a stronger assembly. This research consist of the axial type internal magnetic spur gear modeling process, then simulate it on software based on finite element analysis with transient mode which included assembly of magnetic gear components, material selection, region settings, meshing settings, boundary and excitation settings, then moving gear determination by making bands, sets up models by setting the gear to rotate with 20 rpm rotation, validate, set up analysis, and post-processing for results analysis. Simulations are carried out with dimension variations of permanent magnets in radial, axial, and tangential. Based on the simulation results on the axial type internal magnetic spur gear, the dimensions in radial direction affect the increase in torque by 11,9 %, each increase by 10 mm. The dimensions in axial direction affect the increase in torque by 62,05 %, each increase by 10 mm, and the dimensions of tangential direction does not significantly affect the increase in torque
