When using some hard-tooth surface reducer equipment, we often encounter some hard-tooth surface reducer gear deviation phenomena. The following describes how to deal with the occurrence of hard-tooth surface reducer gear deviation.
The comprehensive total deviation of the gear section of the hard-toothed 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.
Cumulative total deviation of pin wheel pitch of hardened gear reducer: on the center circle of the pin tooth, the maximum pitch deviation of any arc segment of the tooth profile on the same side of the pin tooth.It is expressed as the total amplitude of the pitch cumulative deviation curve.
The comprehensive deviation of the gear tooth section of the hardened reducer: the comprehensive deviation of the section within any pitch angle of the gear.
The cumulative total deviation of the gear pitch of the hardened gear reducer: the maximum cumulative deviation of the tooth pitch in any arc segment of the tooth surface on the same side 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 pitch cumulative deviation curve.
Single tooth pitch deviation of the pin wheel of hard tooth surface 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 the pin wheel pitch of the hard-tooth surface reducer: on the center circle of the pin tooth, the algebraic difference between the actual arc length and the theoretical arc length of any K pitches.It is equal to the algebraic sum of the individual tooth pitch deviations of the K tooth pitches.The tooth pitch number K is given by the design.
The accumulative deviation of the gear pitch of the hardened gear reducer: the algebraic difference between the actual arc length and the theoretical arc length of any K tooth pitches.In theory it is equal to the algebraic sum of the individual pitch deviations of the K pitches.The tooth pitch number K is given by the design.
Gear tooth profile deviation of hard tooth surface reducer: In a complete tooth profile on the end plane, the actual tooth profile deviates from the design tooth profile, which is calculated in the normal direction of the design 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 the cycloidal gear, and the designed tooth profile refers to the tooth profile that meets the design requirements.
Gear tooth deviation of hard tooth surface reducer: On a cylindrical surface close to the middle of the tooth high and coaxial with the gear axis, in the working part of the tooth width, the end surface distance between the two theoretical tooth lines that contain the actual tooth line.Gear top-to-root distance deviation: the difference between the actual distance and the theoretical distance between the tooth top of any gear tooth and a tooth root at a relative 180-degree central angle.For a cycloidal gear with an even number of teeth, it is the difference between the actual diameter and the theoretical diameter of the addendum circle or dedendum circle.
Radial circular runout of the gear tooth profile of a hardened gear reducer: within the range of one revolution of the gear, the probe contacts the tooth profile in the tooth groove on both sides near the high center of the tooth, and the maximum variation of the probe position relative to the gear axis.
