  1. MICE Installation and Commissioning meeting RAL, 13 June 2007 Diffuser - Gear design. Joe Tacon - Oxford University

  2. Gear Box Speeds and ratios:Gear Box 1: Gear Box 1: Finger Main Rotation: Input Speed: 200 RPM Input Torque: 3 Nm Output Speed: 0.33 RPM (1 turn every 3 minutes) Total gear ratio: 200 / 0.33 = 600:1 Output torque: 600 x 3 = 1800Nm Gear ratio of the drive gears: Gear A (Central Gear Drive) = 17 teeth. Gear B (Central Gear Rotation) = 51 teeth. Gear ratio: 51 / 17 = 3:1 Gear box ratio needed: 600 / 3 = 200:1 A B

  3. Gear Box Speeds and ratios:Gear Box 2: Gear Box 2: Bayonet Gear Drive: Input Speed: 200 RPM Input Torque: 3 Nm Output Speed: 0.5 RPM (10 seconds to rotate 30 degrease) Total gear ratio: 200 / 0.5 = 400:1 Output torque: 400 x 3 = 1200Nm Gear ratio of the drive gears: Gear A (Central Gear Bayonet Drive) = 10 teeth. Gear B (Central Gear Ring Internal) = 95 teeth. Gear C (Central Gear Ring External) = 110 teeth. Gear D (Bayonet Gear) = 90 teeth. A to B = 95 / 10 = 9.5:1 C to D = 90 / 110 = 0.818181818:1 Total ratio = 0.818181818 x 9.5 = 7.772727273:1 Gear box ratio needed: 400 / 7.772727273 = 51.4619883:1 (51:1) A B C D

  4. Gear Box Speeds and ratios:Gear Box 3: Disk Carrier Movement: Thread pitch = 6mm 4 Start Thread = 6 x 4 = 24mm Distance moved in 1 min = input RPM x Pitch = 25 x 24 = 600mm per min Gear Box 2: Bayonet Gear Drive: Input Speed: 200 RPM Input Torque: 3 Nm Output Speed: 25 RPM Total gear ratio: 200 / 25 = 8:1 Output torque: 8 x 3 = 24Nm Gear ratio of the drive gears: Gear A (Diffuser Drive Gear) = 45 teeth. Gear B (Diffuser Idler Gear) = 145 teeth. Gear C (Cylinder Gear) = 129 teeth. A to B = 145 / 45 = 3.222222222:1 B to C = 122 / 145 = 0.84137931:1 Total ratio = 0.84137931 x 3.222222222 = 2.711111111:1 Gear box ratio needed: 8 / 2.711111111 = 2.950819672 (3:1) A B C

  5. Epicyclic Gear Arrangement: Output Input For 1 rotation of shaft L shaft S rotates: ( 1 + NA / NS ) Gear Ratio: (1+42/14) = 4:1 with shaft S as the input.
