Figure 7-5 shows two meshing gears contacting at point K 1 and K 2. Hardware, Metric, ISO
Tangential Forces on Spur Gear Teeth The tangential force between spur gear pairs is the force that is tangential to the pitch line. Power is completely transmitted with this force. Input the gear's tooth count, pitch (or module), and pressure angle to calculate the pitch diameter, root diameter, and outer diameter. c The fillet radius of the basic rack should not exceed 0.235/P for a 20-degree pressure angle rack or 0.270/P for a 25-degree pressure angle rack for a clearance of 0.157/P. Good app - it really lets you see what you are doing when pairing your gears. When teeth mesh, the load is delivered to the teeth with some degree of impact. Should you genuinely need to adopt a non-standard diametric pitch for your pinion-gear assembly that results in an unacceptable tooth profile, it may be possible to correct any shape peculiarities by altering the addendum and/or dedendum factors (F and F respectively). Whether you're looking to design a new transmission from scratch, reverse engineer a broken gear, set up small scale manufacturing, or refurbish and upgrade a machine. The world of gears is very interesting to me because of the rich history they have, their interesting complexities, their apparent simplicity, and how a new gear train feels when processed and meshed just right.
