20 Degree Pressure Angle
Posted by Joe Johnson.   [PICTURE: SAME | NEW | HELP]
Engineer on team #47, Chief Delphi, from Pontiac Central High School and Delphi Automotive Systems. Posted on 7/13/2000 8:49 AM MST In Reply to: Re: Fisher price motor gear specs posted by Amy on 7/12/2000 6:45 PM MST: The gears are all standard, full depth, 20 degree pressure angle, English pitch gears. The gears are slightly modified to help them with strength & mfg. issues, but it is my understanding that the modifications are not too signifcant (they will all run fine with standard steel gears). A tip for getting the Diametral Pitch of full depth gears: DP = (Number of teeth + 2) / (Outside Diameter of the Gear) I have not looked at the gears in a while, but I recall that the pitches are 32 at the motor pinion and 20 at the output gear. I suppose that the intermediat gears are 24 pitch as that is the only common English D.P. in between 20 and 32. Good luck. Joe J. |
