Wheel teeth (teeth) -end the raised part of the gear for meshing. Generally speaking, these raised parts are arranged in radiation. The pairing gears are in contact with each other, causing the continuous meshing of the gear.
Agex — space between the two adjacent wheels on the gear.
End surface -the plane perpendicular to the gear or snail axis on the cylindrical gear or cylindrical worm.
Faluni -On the gear, the French surface refers to the plane vertically on the wheel tooth line.
The top of the teeth -the circle at the top of the tooth.
Round of teeth -the circle at the bottom of the groove.
The base circle -forming a ranging line formed on it as a pure rolling circle.
Summary circle -Calculate the reference circle of geometric size in the end surface. For the straight gear, the modulus number and the pressure angle of the division circle are standard values.
The tooth surface -the surface of the wheel tooth is located on the side surface between the cylindrical surface and the cylindrical surface of the tooth.
Teeth profile ─ The dental surface is cut off by a specified curved surface (to the cylindrical gear).
Teeth lines -the intersection of the tooth surface and the cylindrical surface.
The end surface tooth distance PT -the length of the arc length between the neighbor's two teeth at the end of the teeth of the teeth.
Modulus m – the quotient of the tooth pitch divided by pi π, in millimeters.
The countdown of the diameter P─ -Model is in the inch.
Teeth thickness S ─ The length of the arc length between the tooth outline on the ends on the end surface.
Glot width E ─ ─ The score arc length between the tooth profiles on both sides of the altitude on the end surface.
The radial distance between the top height of the tooth top and the division circle.
The radial distance between the teeth height HF ─ ─ The radial distance between the division circle and the round of the teeth.
The radial distance between the whole teeth height H ─The teeton peak and the root circle.
Teeth width B -The size of the wheel tooth is axial.
The end surface pressure angle ─ ─ ─ The radial line of the intersection of the interlaced point of the end surface and the division round is the sharp angle of the tooth cut line of that point.
Standard Rack: Only the size of the base, the tooth shape, the height of the whole teeth, the high tooth crown, and the thickness of the tooth thickness are aligned with the standard positive gear specifications. Called as the benchmark graphics.
Standard Pitch Circle: It is used to determine the size of each part of the gear.
Standard Pitch Line: A specific section line on the rack or the thick tooth thickness measured along this line is one -half of the distance.
Action Pitch Circle: When a pair of positive gear bite, each has one other rolling circle.
Standard Pitch: Select the standard for the standard for the benchmark, and equal to the benchmark graphics.
Pitch Circle: The two gear connecting the lines on the line of contact point is left on each gear of each gear.
Pitch Diameter: Diamond diameter.
Working depth: A pair of positive gear tooth crowns high. Also known as working tooth height.
Grand Crown: Board of Top Glutter and the Railial Railway.
Backlash: During the two teeth, the gap between the teeth and the tooth surface.
Cleaarence: During the two teeth, the gap between the top of the gear tooth and the bottom of the gear.
Node (Pitch Point): a pair of gear bite and the cutting point of the ball.
Pitch: A relative point arc distance between the adjacent teeth.
Normal Pitch: Gradual gear along the same vertical line of the same section on the same section of the gear.
Transmission ratio (): The ratio of the speed of the two gears, the speed of the gear is inversely proportional to the number of teeth, and generally use N1 and N2 to indicate the speed of the two mesh to teeth
