Drawing Spur Gear Diagram
The involute profiles were calculated using the 2 cubic bézier approximation.
Drawing spur gear diagram. Calculate and draw the pitch circle. Begin by laying out the pitch root and outside circles of the 36 tooth gear. Then from each part unwrap a cord drawing a line with a pencil.
Figure 7 below shows how to draw a diagram of this gear system which has a 15 tooth driver gear and a 30 tooth driven gear. In addition it let you compose full gear layouts with connetcted gears to design multiple gears system with control of the input output ratio and rotation speed. Internal gears or ring gears may be drawn with similar efficiency.
The diameter of the pitch circle is calculated below. Tooth shape is often described as a specification in drawing of a spur gear as indicated by the height of teeth. In this example we will draw the 36 tooth 24 pitch spur gear.
Looking generally the involute shape is the most wide spread gear tooth form due to among other reasons the ability to absorb small center distance errors easily made production tools simplify manufacturing thick roots of the teeth make it strong etc. Start by drawing a horizontal centre line for both gears. Gear generator is a tool for creating involute spur gears and download them in svg format.
Gears can be animated with various speed to demonstrate working mechanism. Look at the meshing gears in figure 6 on the previous page. When an intermediary gear set or idler gear is introduced between the two gears the drive gear gear 1 and the last gear gear 3 will rotate in the same direction.
Gear design spur gea. P n d 1 5. Using this example you will be able to draw a spur gear having any number of teeth and pitch.
So if you had a 8 18t pinion gear you d want a 13t pinion gear. First divide a cylinder into eight equal parts. Diagram of a spur ge.
How to draw meshing gear systems. Let us try to make a simple drawing of an eight toothed gear. That is after all why people pay engineers.
Cogs and gears drawing. Backlash of 0 2 mm was added by increasing the center. Internal gear drawing example.
After you have completed eight lines do the same manual work from the opposite side. The diagram thus drawn is the involute tooth profile. 6 shows an internal gear and pinion with module value of 5 mm.
Play with the numbers and you realize you can go with a 10t pinion and a 17t spur gear that comes pretty close to what you want that being said you need to come up with your own solution or provide more details on your needs. Steampunk gears and cogs drawing. 6 3 1 6 illustration of center to center distance of gears in mesh.
