How do I choose a gearbox motor?

How to Select a Gearbox

  1. Speed and horsepower of the input.
  2. Desired output speed or desired output torque (will determine ratio)
  3. Characteristics of use; hours per day, nature of shock or vibration in the system.
  4. Degree of overhung load.
  5. Unit configuration, shaft input or hollow bore input, shaft output or hollow bore output.

How do you calculate gearbox size?

The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).

Does a gearbox increase power?

It is impossible to increase power in a gearbox. Power is rate at which work is done or energy used and has units of Joules/second. A gearbox can only lose power to bearing drag, gear meshing loss, oil churn and windage. The power output from a gearbox is always less than power input.

Does gearbox increase speed?

But while gearboxes multiply torque, they reduce speed. (This is why they’re sometimes referred to as “gear reducers” or “speed reducers.”) In other words, when a gearbox is attached to a motor, the motor must turn faster — by a factor equal to the gear ratio — to deliver the target speed to the load.

How is motor conveyor rating calculated?

Divide your linear speed you desire for the belt in m/s by the circumference of your drive drum in metres to get revolutions per second. For example, 0.3m/s / 0.45m = 0.66′. Multiply this number by 60 to get RPM. 0.66*60 = 40 RPM.

What are the selection factors for the gearbox?

Which motor is suitable for conveyor belt?

AC induction motors are ideal for conveyor systems that operate continuously in one direction. For conveyor systems where the load must be held in place or for vertical applications, there are a wide range of AC motors with power-off activated electromagnetic brake.

What is a DC gear motor?

A Direct Current (DC) motor is a rotating electrical device that converts direct current, of electrical energy, into mechanical energy. … Inside the motor is an iron shaft, wrapped in a coil of wire.

How do you check a gearbox on a motor?

Methods for Inspecting a Gearbox

  1. Visual walkaround.
  2. Visual inspection through inspection ports.
  3. Borescope inspection.
  4. Measure temperature. Thermometers. Resistance temperature detector (RTD) probes. Thermography.
  5. Measure oil pressure.
  6. Measure sound and vibration.
  7. Inspect filter elements.

How do you test a gear motor?

The most basic level of motor or gearmotor testing that is performed is a Speed/Torque Test. This test is performed by coupling the test motor to a dynamometer. The test starts with zero torque load on the motor shaft and the rotational speed is measured at increasing torque loads until a curve is generated.

What are the types of gearbox?

Different Types of Gearbox

  • Helical gearbox.
  • Coaxial helical inline gearbox.
  • Bevel helical gearbox.
  • Skew bevel helical gearbox.
  • Worm reduction gearboxes.
  • Planetary gearbox.


How many gears does a gearbox have?

Contemporary manual transmissions for cars typically use five or six forward gears ratios and one reverse gear, however, transmissions with between two and seven gears have been produced at times.
