How do you calculate worm gear torque?

Twg = L * r

  1. Where Twg is the Worm Gear Torque (N-m)
  2. L is the load of the meshing point (N)
  3. 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?

  1. Torque ( = 63,025 x Power (HP) / Speed (RPM)
  2. Power (HP) = Torque ( x Speed (RPM) / 63,025.
  3. Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)
  4. 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.
