Abstract
Drum Support is one of the critical components in a tire building machine, functioning to support the drum load so that the rotation of the mainshaft bearing is not disturbed by uneven load distribution. The tire building machine is a key machine in the tire manufacturing process, responsible for assembling tire components before the curing process. The mainshaft bearing serves as the rotating shaft of the building drum. The RTB-A2 tire building machine recorded the highest downtime and spare part consumption, reaching 18,319 minutes in 2025. The high downtime was caused by mainshaft bearing failures due to seizure, which occurred because the drum support was not optimal in supporting the drum load. Under normal conditions, the mainshaft bearing is replaced once a year; however, during the period of August 2025–September 2025, three bearing replacements were required, resulting in a total downtime of 6,887 minutes. Therefore, a modification was carried out by redesigning the drum support to improve its load-bearing capability and reduce the workload on the mainshaft bearing. The modification focused on the working principle of the drum support in supporting the load. The previous design utilized a bolt-bushing cross-section, while the modified design employed an arm system to support the drum load during rotation. Finite Element Analysis (FEA) was used as a numerical analysis method to obtain approximate solutions to engineering problems. The drum support modification was designed using the finite element approach with SolidWorks software. Additionally, weld joint and bolt strength calculations were performed to ensure that the modified design was safe for implementation. After the drum support modification, the machine downtime during the October 2025–December 2025 period decreased to 846 minutes, representing a reduction of approximately 87.71%. As a result, spare part costs for the machine were significantly reduced. Keywords: Modification, Drum Support, Finite Element Analysis, Mainshaft Bearing Drum Support merupakan salah satu komponen penting pada mesin tire building yang berfungsi menopang beban drum agar putaran bearing mainshaft tidak terganggu akibat distribusi beban drum yang tidak merata. Mesin tire building adalah salah satu mesin dalam tahapan proses pembuatan ban yang berfungsi merakit material penyusun ban sebelum proses curing. Bearing mainshaft berfungsi sebagai poros putar drum building. Mesin tire building RTB-A2 merupakan mesin dengan down time dan pemakaian sparepart tertinggi yaitu 18.319 menit pada tahun 2025. Tingginya waktu downtime tersebut diakibatkan oleh kerusakan bearing mainshaft yang macet dikarenakan fungsi dari drum support yang tidak maksimal dalam menahan beban drum. Normalnya penggantian bearing mainshaft dilakukan satu tahun sekali, akan tetapi aktualnya selama periode Agustus-September 2025 terjadi tiga kali pergantian bearing mainshaft dengan downtime sebesar 6.887 menit . Maka dilakukan modifikasi dengan mengubah desain drum support agar mampu menahan beban drum lebih baik sehingga memperingan kerja dari bearing mainshaft. Modifikasi dilakukan pada prinsip kerja drum support dalam menahan beban, dimana desain terdahulu menggunakan penampang berupa bolt bushing. Sedangkan pada modifikasi kali ini penampang yang digunakan diubah menggunakan sistem arm dalam menahan beban drum saat berputar. Metode Finite Element Analysis (FEA) merupakan teknik analisis numerik yang digunakan untuk mendapatkan solusi pendekatan dari berbagai permasalahan teknik. Perancangan modifikasi drum support menggunakan pendekatan metode elemen hingga dengan software yang digunakan adalah Solidworks. Kemudian perhitungan sambungan las dan baut dilakukan untuk mengetahui bahwa modifikasi tersebut aman untuk diterapkan. Setelah dilakukan modifikasi pada drum support didapatkan hasil bahwa nilai downtime mesin menurun pada periode Oktober-Desember 2025 dengan total downtime sebesar 846 menit atau menurun sekitar 87,71 % . Sehingga mengurangi biaya pemakaian spare part pada mesin. Kata Kunci : Modifikasi, Drum support, Finite Element Analysis, Bearing Mainshaf
