2. Intersecting Axes / Miter Gear, Straight Bevel Gear, Spiral Bevel Gear.
3. Nonparallel, Nonintersecting Axes / Screw Gear, Worm, Worm Gear (Worm Wheel)
How do bevel gears work?
Bevel gears are power transmission components primarily used 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 intersecting axes and in special cases on shafts whose axes do not intersect.
How do you create gears in CAD?
1. Start AutoCAD.
2. Make 2 circles.

4. Trim the circles side ways.
5. Now enter “bo” command. It will show the boundary creation dialogue. …
6. Click inside the region and then press enter.
7. Now we have the polyline created. …
8. Make a circle of 50mm radius.
How do you draw meshing gears?
1. Step 1: Start by drawing a horizontal centre line for both gears.
2. Step 2: Draw a vertical centre line for the driver gear on the left.
3. Step 3: Calculate the pitch centre distance.
4. Step 4: Measure the centre of the driven gear from the centre of the driver gear.
How do you make a sprocket in Freecad?
1. Go to the menu Part Design → Sprocket.
2. Set the DataNumber Of Teeth and the DataSprocket Reference.
3. Click OK.
4. If the sprocket gear is created outside of the active body, drag and drop it into a body for the application of further features like padding.
How do you make a keyway in AutoCAD?
What is the angle of helical gear?
For single helical gears, the helix angle is generally 12°–20°.
How do you make a helical?
1. In a part, do one of the following: Open a sketch and sketch a circle. Select a sketch that contains a circle.
2. Click Helix and Spiral (Curves toolbar) or Insert > Curve > Helix/Spiral .
3. Set values in the Helix/Spiral PropertyManager.
4. Click .
How is helical gear calculated?
The displacement of the helical rack, l, for one rotation of the mating gear is the product of the radial pitch, pt, and number of teeth. According to the equations of Table 6-7, let radial pitch pt = 8 mm and displacement> l = 160 mm.
Which type of gear is most common?
Spur gears
What are the 5 types of gears?
1. Spur Gear. Spur gears transmit power through shafts that are parallel.
2. Helical Gear. Helical gears have teeth that are oriented at an angle to the shaft, unlike spur gears which are parallel.
3. Double Helical Gear.
4. Herringbone Gear.
5. Bevel Gear.
6. Worm Gear.
7. Hypoid Gear.
