    BALL MILL GEARBOX PROBLEM Vibration

    EVALUATE GEAR RATIOS (REVIEW FACTORING) Our Ball Mill has the following tooth counts: Pinion 18 teeth 1 x 2 x 3 x 3 Bull 226 teeth 1 x 2 x 113 (113 is prime). Thus, the factor common to both of these gears is 2 (improper set). Since we have a common factor other than one between the two gears on the ball mill we can expect to see the appearance of fractional gearmesh frequency and harmonics in

    Principle of operation bowl mill SlideShare

    03/03/2014· Principle of Operation Bowl Mill is driven by AC motor, coupled with flexible coupling to the worm shaft. The worm shaft drives worm gear, mounted on the Main Vertical Shaft. A bowl mounted on the top of the shaft rotates at a speed of 40 to 65 rpm. For a particular mill the speed is constant .Integral coolers are provided in the mill base with circulating water for removing heat from the oil

    4 Easy Ways to Determine Gear Ratio (with Pictures)

    21/05/2011· In our example, the intermediate gear ratios are 20/7 = 2.9 and 30/20 = 1.5. Note that neither of these are equal to the gear ratio for the entire train, 4.3. However, note also that (20/7) × (30/20) = 4.3. In general, the intermediate gear ratios of a gear train will multiply together to equal the overall gear ratio.

    Worm-and-gear sets are a simple and compact way to achieve a high torque, low speed gear ratio. For example, helical gears are normally limited to gear ratios of less than 10:1 while worm-and-gear sets vary from 10:1 to 500:1. A disadvantage is the potential

    Hobbing Wikipedia

    Since the gear ratio between hob and blank is fixed, the resulting gear will have the correct pitch on the pitch circle, but the tooth thickness will not be equal to the space width. Hobbing machines are characterised by the largest module or pitch diameter it can generate. For example, a 10 in (250 mm) capacity machine can generate gears with a 10 in pitch diameter and usually a maximum of a

Pepetools and Durston have gear ratios of 4:1 and Durston also has some with a 5:1 ratio. What does this mean? With a 4:1 ratio, four turns of the handle will roll the rollers one full rotation. Likewise, the 5:1 needs 5 turns for every full rotation. This gear ratio is important because

    24/05/2004· The simple fact is: the gear box ratio will be changed from 25/1 original to 20/1 (proposed). If the actual motor power demand is close to 1500 HP at 1000 rpm, changing the Gear Box Ratio will result in overload of the motor. However if the actual load of the motor is much lower than 1000 HP, it could work with the new gear box.
