returns a combination of two gears

Description

This function creates single stage gear. The function contains spur gears, internal gears, bevel gears and crownwheels. The smaller gear is defined with 14 teeth to avoid undercuts due to gear motion.

Syntax

[SGgp,SGg1,SGg2]=SGgearpair([A,i,sigma,h,di,type])

Input Parameter

A: Shaft center distance as sum of the two radii, default is 20 [mm]; Give positive value for spur gear pair and negative value for gear pair with one internal gear
i: Gear ratio, default is 2.5 []; Has to be divisible by 0.5! Negative value defines a combination of spur gear and gear rack
sigma: Angle between the axis, default is 0 [°]; A value of -90 defines a crownwheel
h: Heigth of the gears, default is 3 [mm]
di: Diameter of an inner bore hole, default is 0 [mm]
type: Flag for the design of helical ('h') or herring bone ('v') teeth, default is '' ['string]

Output Parameter

SGgp: Pair of gears for the gear stage [SGT]
SGg1: First gear of the pair as single SGT [SGT]
SGg2: Second gear of the pair as single SGT [SGT]

SGgearpair(-20,2.5,0,3,0,'') %internal gear stage
SGgearpair(20,2.5,90,5,2,'v') %bevel gear stage
SGgearpair(20,2.5,-90) %gear stage with crown wheel
SGgearpair(20,-1.5,0,3,0,'h') %gear rack with spur gear
