How do you calculate planetary gear?
How do you calculate planetary gear?
To make calculating planetary gear ratios as simple as possible, note the number of teeth on the sun and ring gears. Next, add the two numbers together: The sum of the two gears’ teeth equals the number of teeth on the planetary gears connected to the carrier.
How is gear train calculated?
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).
What is planetary gear ratio?
The planet gears (blue) turn in a ratio determined by the number of teeth in each gear. Here, the ratio is −24/16, or −3/2; each planet gear turns at 3/2 the rate of the sun gear, in the opposite direction.
How is gear train torque calculated?
How to Calculate Gear Ratios and Torque
- Multiply the force acting on the first gear by the first gear’s radius.
- Divide the second gear’s radius by the first gear’s.
- Multiply the gear ratio by the input torque that you calculated in Step 1: 2 x 600 = 1,200 newton-meters.
Is Train value and gear ratio same?
It is the ratio of the speed of driven gears to the speed of the driver gears is known as the train value.
What is train value of gear train?
Train Value: It is the ratio of the speed of driven gears to the speed of the driver gears is known as the train value.
How is a 1 1 ratio achieved using a planetary gear set?
If both sun gears turn in the same direction, the planet gears lockup because they can only spin in opposite directions. This locks the ring gear to the planets and causes everything to spin as a unit, producing a 1:1 ratio.
How to calculate planetary gear ratio?
Planetary Gear System Components. Planetary gears sets have 4 major components: sun,planet (s),ring and the carrier or arm.
How to calculate the gear train?
Step-1 : GR (1-2) = 30/40 = 0.75
What is velocity ratio in simple gear train?
When there is only one gear fitted on each shaft, then this type of gearing system named Simple gear trains. Speed Ratio or You can say Velocity Ratio: It is the ratio of the speed of the driver gears to the speed of the driven gears . The ratio speed of any pair of gear is the inverse of the teeth.
How do you calculate gear ratio?
Gear ratio can be calculated by dividing the diameter of both gears or their number of teeth. If gear ratio > 1 then it’s speed reduction, if smaller then it’s for system to speed up, if equal one it’s just for transmitting power with same speed to transmit it just to another location depending on geometry of design.
