  1. Perancangan Elemen Mesin III*KK- 042304 Lecture 1: Spur Gear1 Disiapkan oleh Dr.-Ing. Mohamad Yamin Center for Automotive Research Universitas Gunadarma

  2. Spur GearOutline • Overview • Konsep Dasar • Kinematika gear • Garis aksi (Line of action), • titik kontak • Involute profile • Terminologi Dr.-Ing. Mohamad Yamin

  3. Overview • Mentransmisikan daya (Power) secara mekanik • Mengubah (mempercepat atau memperlambat) kecepatan putar • Mengubah (menaikkan atau menurunkan) daya (power) atau torsi (torque). • Menjaga rasio kecepatan konstan Dr.-Ing. Mohamad Yamin

  4. Konsep Dasar:Kinematika gear Dr.-Ing. Mohamad Yamin

  5. Konsep Dasar:garis aksi (line of action); titik kontak Dr.-Ing. Mohamad Yamin

  6. Konsep Dasar:Involute profile Dr.-Ing. Mohamad Yamin

  7. Konsep Dasar:Terminologi • Membiasakan diri familiar dengan terminologi gear, akan memudahkan memahami gear! Dr.-Ing. Mohamad Yamin

  8. Konsep Dasar:Center Distance, cd • Center distance • Gear ratio Dr.-Ing. Mohamad Yamin

  9. Konsep Dasar:Pitch • Circular Pitch • Diametral Pitch • Circular pitch harus sama untuk pinion dan gear Dr.-Ing. Mohamad Yamin

  10. Contoh Perhitungan:Geometri spur gear • Sebuah Spur Gear memiliki jumlah gigi Ng=44 gigi, pressure angle (sudut tekan), =20°, dengan diametral pitch Pd = 12 gigi/inch • Diameter Pitch, Dg • Circular Pitch, Pc • Addendum, a Dr.-Ing. Mohamad Yamin

  11. Contoh Perhitungan:Geometri spur gear • Dedendum, b • Clearance, c • Thoot thickness (ketebalan gigi), t Dr.-Ing. Mohamad Yamin
