venkatagopal,

Please give more technical details of your project if you want an answer.

Dear Mr. Venkatagopal,

What type of drive base you want to design? Specify the type of equipment for which drive base is designed for. Give complete details

I guess the basics may include:

Alignment of equipment (fit for service)

Strength (suitable strength)

Criteria, may include suitably designed to maintain alignment for transportation, consideration of abnormal prime mover conditions, some allowance for the force associated with simple harmonic motion of the drive base if it has a low speed coupling and the final TIR is “so so” (though shouldn’t be significant - probably should address the TIR rather than beef up the base), vibration analysis to ensure the natural frequency is no where near the frequencies generated by the drive during normal running.

Hopefully the rest is just mechanics.

Regards,

Lyle

The drive base may be designed to support motor, high speed couplings, flywheel and its pedestals, brakes, holdbacks and reducer.

Flywheels can be set between motor and reducer or on an extension of high speed shaft with parallel configuration.

Holdbacks can be integral with brakes (not a good idea) and mounted on high or low speed shaft with the necessary supports.

There are fixed drive bases for parallel and right angle reducers.

There are floating or swing base supports for right angle drives which support the above.

There are criteria for swing-base designs to cancel the shaft bending stress in two horizontal planes at a given load on the belt.

Which of the above apply?

Hi there..

Mount all Drive equipment on common baseframe for shaft mounting.

Support the drive unit on a single torque arm along the centre-line of the drive and directly under the motor output shaft.

Calculate reaction forces, and determine the deflections produced.

These must be sufficiently small so that the drive alignment will stay within the requied tolerances for all operating condotions.

Mount the drive on the drive pulley shaft end with the usual rigid flange low-speed coupling.
