How to calculate the output force of gear

1.

"Mechanical design" textbooks are used in the "grip line" rule: "left spiral with left, right spiral with right hand. Holding the axis of the driving wheel, except for the thumb, the other four fingers represent the direction of rotation. The thumb points to the direction of the driving wheel axis to the force, and the direction of the force from the driving wheel axis is opposite to that of the driving wheel axis, and the size is equal to that of the driving wheel axis. This rule only applies to driving wheels

let's see whether it's a left-handed or a right-handed gear, left-handed, right-handed, four fingers circling in the same direction as the gear rotation, with the thumb straight. If it is a driving wheel, the axial force is the same as that of the thumb; if it is a driven wheel, the axial force is opposite to that of the thumb

axial force example

the axial force is inertial force. When an object rotates, it will proce a centripetal acceleration e to the existence of angular velocity. Generally, when an object rotates, it has an instantaneous axis, so it can be regarded as rotating around the instantaneous axis, So the centripetal acceleration points to the instantaneous axis. The direction of inertial force is just opposite to that of centripetal acceleration, which is called axial force

generally, the magnitude of inertial force is related to the angular velocity, mass, shape, and centroid of an object, which can not be solved by a simple formula. When a particle rotates around a fixed axis, the centripetal force F = m * W ^ 2 * r. m is the mass of the particle, W is the angular velocity of rotation, and R is the radius of rotation. If a rigid body rotates on its fixed axis, it will proce inertial force, which belongs to static balance and dynamic balance

2. "The inner diameter of a gear with a pitch diameter of 80 is 16". Why not increase the gear diameter and shaft diameter, and use key connection to transfer power
"axial pressure greater than 100kg is required to fit into the shaft." With such a large pressing force, the shaft with diameter of 16 is easy to bend.

3. Gear transmission changes the speed and torque, and the meshing force is the relationship between the force and the reaction force

4. 100 Newton, 0.5 m and 0.25 m
small torsion force at least 200 n

5. I don't know... But I remember the teacher said that it is related to the angle of meshing of two gears

6. The interaction forces between gears include circumferential force, radial force and axial force.

1. The load a on the left side of the pulley will be balanced by the wire rope on the right side of the pulley, that is, the wire rope on the right side will have a downward force equal to a

2, and there is a downward force a on the left side of the big gear d, then: there is also a force equal to a on the right side of the big gear, and the direction is opposite

3, (C / 2 is the radius of the pinion)

4. So: make the pinion proce torque M, that is, the force we must apply to the pinion. A

5. To sum up, such a mechanism does not save labor, only the moving pulley can save labor (as mentioned in Middle School Physics)

6. The torque of the gear M = the force acting on the gear indexing circle × Radius of gear indexing circle

7. In this problem, the torque of pinion M1 = (C / 2) × A

8. Torque of big gear M2 = (D / 2) × A

I hope the above can help you

The output torque of gear recer should be calculated by the following formula:

output torque = input torque * transmission ratio * transmission efficiency

When the power is fixed, the engine torque is inversely proportional to the engine speed. The faster the speed is, the smaller the torque is, and vice versa. It reflects the load capacity of the vehicle in a certain range

extended data

the transmission ratio of component A and component B is I= ω a/ ω B = Na / Nb, where ω A and ω B is the angular velocity (radians per second) of components a and B respectively, Na and Nb are the rotational speed (revolutions per minute) of components a and B respectively

When the angular velocity is instantaneous, the transmission ratio is instantaneous. When the angular velocity in the formula is the average value, the transmission ratio obtained is the average transmission ratio

10. 1. "Use one big and one small gear to build a gear train. Which gear turns faster? Drawing instructions. "
answer: if the big gear is the driving gear and the small gear is the driven gear, the rotation speed of the small gear will be faster
the formula is: Z1 * R1 = Z2 * R3, of course, the premise is that the gear molus is equal! That is to say, the two basic dimensions should be able to mesh
2. "If you add a middle gear and use three gears in total, will the rotation direction of the last gear change? Draw a picture. You can use the text diagram
"
A: the direction of rotation of the last gear is the same as that of the first gear
3. "Add more gears. When you drive the driving wheel, what's the rotation direction of each gear? Draw a picture. You can use a text map. "
A: I don't need to answer the following questions after answering the above two questions, and so on!
