Gear ratio. i = If the rotor inertia and the gear ratio are unknown, the acceleration torque will be calculated with an inertia ratio of 5:1 (see the motor selection tips that will appear on the result window for the detail). Positioning distance. L = in mm . Positioning time. …
To use the chart, find the point where 2 hp and 15:1 ratio intersect. In this case, that indicates a size 726 gearbox. According to one manufacturer's product-number system, size 726 defines a gearbox that has a 2.62 center distance. Such charts also work in reverse, to let engineers confirm the torque or speed of a given gearbox size.
Belt conveyors used to transport minerals are to be found all around the world in a large number of surface and underground mining operations. The idea of using the conveyor belt is not new, indeed, the first bell conveyors were introduced at the end of the nineteenth century; the basic principles of operation have not changed.
Answer: To calculate the speed of conveyor belts,we must know the circumference of drive roller and revolutions per minute. The product of the perimeter of the roller and revolutions per minute gives us the speed of the conveyor belts. If suppose we have a motor speed as 1440 rpm, and having g...
ERotating direction of the belt is the same as motor rotating direction when gear ratio is 25 or less, and the opposite when gear ratio is 30 or more. EFor connection diagram and inverter details, see P.1091~. EFor Flat Belt details, see w P.1097.

BELT = weight of belt or roller (oz.) J MOTOR = motor inertia (oz-in-sec2) r = radius of roller, screw, gear or pulley (in.) E = gearmotor gear efficiency (contact factory) ϕ = angle of screw or belt from horizontal (degrees) n = number of rollers R = gearmotor gear ratio t a = time to accelerate (sec.) N = speed (RPM) V
Gear Reduction Formula. The following equation is used to calculate the output values of a gear reduction. OT = IT * GR. ORPM = IRPM * GR. Where OT is the output torque. IT is the input torque. GR is the gear reduction ratio. ORPM is the output RPM. IRPM is the input RPM.

The drive unit for a screw conveyor is typically designed with a gear reducer and motor. The drive unit for a screw conveyor is not 100-percent efficient. There are frictional losses in the gear reducer and belt/chain reduction. Drive efficiency (e) is typically between 85 and 95-percent.
Answer (1 of 3): Thanks for A2A.. Conveyor belt is used power plant industries a well as in any assembly line . Huge load is driven by the conveyor belt so the motor needs very high starting torque greater than their running torque . Actually DC series motor operated with very high starting torq...
The gear ratio is the ratio of the number of turns the output shaft makes when the input shaft turns once. In other words, the Gear ratio is the ratio between the number of teeth on two gears that are meshed together, or two sprockets connected with a common roller chain, or the circumferences of two pulleys connected with a drive belt.
