Hard tooth surface reducer gear pitch cumulative deviation: the algebraic difference between the actual arc length and the theoretical arc length of any K tooth pitch. In theory, it is equal to the algebraic sum of the individual pitch deviations of these K tooth pitches. The tooth pitch number K is given by design.
Hard tooth surface reducer gear tooth pitch cumulative total deviation: The maximum tooth pitch cumulative deviation within any arc segment of the same side tooth surface of the gear reducer (K=1 to K=Zc, Zc is the number of teeth of the cycloid gear). It is expressed as the total amplitude of the cumulative deviation curve of the tooth pitch.
Gear tooth profile deviation of hardened gear reducer: In a complete tooth profile on the end plane, the actual tooth profile deviates from the designed tooth profile by the amount calculated in the normal direction of the designed tooth profile. The complete tooth profile refers to the tooth profile corresponding to a theoretical tooth tiger angle between the tooth roots of any two adjacent gears of the cycloid gear, and the designed tooth profile refers to the tooth profile that meets the design requirements.
Tooth direction deviation of hard-tooth surface reducer gear: On a cylindrical surface close to the middle of the tooth height and coaxial with the gear axis, in the tooth width working part, the end surface distance between the two theoretical tooth trajectory lines containing the actual tooth trajectory line.
Gear tip root distance deviation: the difference between the actual distance and the theoretical distance between the tooth tip of any tooth of the gear and the tooth root on the relative 180 degree central angle. For cycloidal gears with an even number of teeth, it is the difference between the actual diameter of the addendum circle or the root circle and the theoretical diameter.
Radial circle runout of gear tooth profile of hardened gear reducer: Within the range of one revolution of the gear, the probe is in contact with the tooth profile on both sides of the tooth profile near the middle of the tooth height, and the probe position is the maximum amount of change relative to the gear axis.
The comprehensive total deviation of the gear cross-section of the hardened gear reducer: On the end plane, the distance between the two equidistant lines of the design tooth profile trace that contains all the actual tooth profile traces.
The comprehensive deviation of one-tooth section of the hardened gear reducer: The comprehensive deviation of the section within any pitch angle of the gear.
Pin wheel pitch deviation of hardened gear reducer: On the end plane, the algebraic difference between the actual arc length and the theoretical arc length of the pin tooth center circle between any two adjacent tooth profiles on the same side.
Cumulative deviation of pin wheel tooth pitch of hard tooth AC Gear Motors Factory: The algebraic difference between the actual arc length of any K tooth pitch and the theoretical arc length on the center circle of the pin tooth. It is equal to the algebraic sum of the individual pitch deviations of these K tooth pitches. The tooth pitch number K is given by design.
Cumulative total deviation of pin wheel tooth pitch of hard tooth surface reducer: The maximum tooth pitch deviation of any arc segment on the same side of the pin tooth on the center circle of the pin tooth. It is expressed as the total amplitude of the cumulative deviation curve of the tooth pitch.
