Processing Method for Deviation of Gear Reducer?
When using some plane double enveloping gear reducer equipment, we often encounter some gear deviation phenomena. Today we will talk about the single gear pitch deviation: on the end plane of the screw elevator, on a circle close to the middle of the tooth, which is concentric with the axes of the gear reducer, the algebraic difference between the actual pitch and the theoretical pitch.
Cumulative deviation of gear reducer pitch: the algebraic difference between the actual and theoretical arc lengths of any K pitches. In theory, it is equal to the algebraic sum of each single pitch deviation of the K pitches. The pitch number K is given by the design.
Total accumulated pitch deviation: The maximum accumulated pitch deviation in any arc section of the same side tooth surface of gear reducer (K=1 to K=Zc, Zc is the number of teeth of cycloidal gears). It represents the total amplitude of the cumulative deviation curve of pitch.
Gear profile deviation: In a complete tooth profile on the end plane, the actual tooth profile deviates from the normal calculation value of the designed tooth profile. The complete tooth profile refers to the tooth profile corresponding to a theoretical tooth tiger angle between any two adjacent tooth roots of cycloidal gears. The designed tooth profile refers to the tooth profile that conforms to the design requirements.
Gear Tooth Direction Deviation: On a cylindrical surface close to the middle part of the tooth and the coaxial axis of the gear, in the working part of the tooth width, the distance between the two theoretical tooth orientation lines containing the actual tooth orientation line is included.
Root pitch deviation of gear top: The difference between the actual distance and the theoretical distance between the tooth top of any gear tooth and one of its roots at the relative 180 degree center angle. For cycloidal gears with even number of teeth, the difference between the actual diameter of the top circle or the root circle and the theoretical diameter is obtained.
Gear profile radial circular runout: In the range of gear rotation, the probe contacts with the tooth profile in the alveolar on both sides near the middle part of the tooth, and the maximum variation of the probe position relative to the gear axis.
General deviation of gear cross section: On the end plane, the distance between two equidistant lines is designed for the joint containing all the actual tooth profiles.
Comprehensive deviation of gear-tooth cross-section: The comprehensive deviation of the cross-section within any pitch angle of the gear.
Single pitch deviation of needle wheel: On the end plane, the algebraic difference between the actual arc length and the theoretical arc length of the center circle of the needle tooth between any two adjacent homologous tooth profiles.
Cumulative deviation of pinwheel pitch: The algebraic difference between the actual arc length of any K pitches and the theoretical arc length on the center circle of pin teeth. It is equal to the algebraic sum of the individual pitch deviations of the K pitches. The pitch number K is given by the design.
Cumulative total deviation of needle gear pitch: On the center circle of the needle tooth, the maximum deviation of the same side of the needle tooth profile at any arc. It represents the total amplitude of the cumulative deviation curve of pitch.
