# How do you calculate worm gear torque?

## How do you calculate worm gear torque?

Twg = L * r

- Where Twg is the Worm Gear Torque (N-m)
- L is the load of the meshing point (N)
- r is the radius of the pitch circle (m)

## Are worm gears good for torque?

Worm gearboxes are low cost solutions for producing high torque from relatively small electric motors. Their output shaft is at a 90 degree angle to the motor input shaft and higher reduction ratios are obtained compared to conventional gearbox designs.

**How do you calculate the torque of a gear motor?**

Gear Reducer Torque = 9550 * Motor power / Rated Power motor’s input revolution*Ratio* gear reducer efficiency. The above calculation is the torque equation. Motor power = torque ÷ 9550 × Rated power’s motor input speed /Ratio /service factor.

**How is worm gear calculated?**

1) Fine-pitch worms and worm gears are generally used to transmit motion (linear or rotary) as opposed to power or torque….Worm Gear Formula Table.

To Find | Rule | Formula |
---|---|---|

Worm Lead | Divide 3.1416 by Diametral Pitch and Multiply by Number of Threads in Worm | Worm Lead = 3.1416 x Number of Threads in WormDiametral Pitch |

### How do you calculate rpm torque?

- Torque (lb.in) = 63,025 x Power (HP) / Speed (RPM)
- Power (HP) = Torque (lb.in) x Speed (RPM) / 63,025.
- Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)
- Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.

### Why does a worm gear increase torque?

Worm gear reducers are perennial champions as far as returning torque for the buck. Why? Because they provide more input shaft rotations per output shaft rotations.

**When should I use worm gears?**

Worm gears are power-transmission components primarily used as high-ratio reductions to change the direction of shaft rotation and to decrease speed and increase torque between non-parallel rotating shafts. They are used on shafts with non-intersecting, perpendicular axes.

**Do gears multiply torque?**

The associated torque is quantified by multiplying the circumferential component by the radius; larger gears experience a greater amount of torque, whereas smaller gears experience less torque. Similarly, the torque ratio is equal to the ratio of the gears’ radii.

## How do you calculate the speed of a worm wheel?

The speed transmission ratio of a worm and worm gear set is obtained by dividing the number of teeth of the worm gear by the number of threads of the worm.

## How do you count teeth on a worm gear?

Generally, the mesh has a 90° shaft angle. The number of threads in the worm is equivalent to the number of teeth in a gear of a screw type gear mesh. Thus, a one-thread worm is equivalent to a one-tooth gear; and two-threads equivalent to two-teeth, etc.
