What is a gear rack?

Gear rack is a particular gear whose teeth are distributed about the strip.
1. The basic concept:
The rack can be split into a rack and a rack, which are paired with a spur gear and a helical gear, respectively; the tooth account of the rack is normally a What is a gear rack? rack and pinionstraight line instead of an involute (planar for the tooth surface) , equivalent to the indexing circle radius is definitely infinite cylindrical gear.
2. The main features:
(1) Since the tooth profile of the rack is direct, each point in the tooth profile has the same pressure position and is equal to the inclination position of the tooth profile. This angle is called the tooth position and the Planetary Gear box typical value is 20°.
(2) The same pitch and modulus are provided on any of the straight lines parallel to the very best line.
(3) A range parallel to the very best type of the tooth and having a tooth thickness add up to the width of the tooth groove is called a dividing collection (middle line), which is a reference series for calculating how big is the rack.
3. The main parameters:
Groove width, high tooth tip, high root elevation, tooth elevation, tooth thickness, root radius, etc.
4. The decision of parameters:
(1) Whether the gear is beating, the entire tooth depth, the normal normal line, the tooth path is qualified, the tooth pitch is poor, and the circumferential section mistake has gone out of tolerance.
(2) If the installation distance following the and racks are installed is suitable.
(3) The rack and gear meshing clearance ought to be 0.25* modulus.
(4) Whether the full tooth depth, runout, and common normal type of the rack are skilled.
5. Processing methods:
Gear rack and pinion machining method:
(1) hobbing
(2) gear shaping
(3) shaving
(4) grinding teeth
(5) molars
