InactiveCN105156637AReduce weightIncrease thrust-to-weight ratioPortable liftingGearing elementsAviationGeometric design
The invention discloses a skew line tooth surface gear transmission pair and a tooth width geometric design method. The skew line tooth surface gear transmission pair adopts an alternating axis transmission form composed of involute spur gears and skew line tooth surface gears. Each skew line tooth surface gear is formed by spreading straight tooth involute slotting cutters in a staggered mode; the skew line tooth surface gears can only mesh with the straight tooth cylindrical gears and can not mesh with the skewed tooth cylindrical gears with helix angle; and the tooth trace is approximate to a skew line and forms an oblique angle with the radius direction, thereby being very suitable for the demands of design diversification for aviation compact space. The method illuminates the gear shaping principle of the skew line gear and skew line tooth surface gear, and deduces the tooth surface equation of the skew line tooth surface gear. The margin line of the involute slotting cutters is utilized to calculate the position of the tangent point of the internal end tooth root. The condition that the outer end tooth top tooth thickness is equal to zero is utilized to obtain the sharpening condition. The condition of avoiding secondary cutting of the tooth root is combined with determine the cutter top fillet radius, thereby finally obtaining the tooth width of the skew line tooth surface gear.
