TERMS AND DEFINITIONS
GB/T10107.1 the basic planetary transmission terms of cycloidal-pin wheel and JB/T10419 cycloidal-pin wheel planetary transmission, cycloid gear, pin wheel, and accuracy terms all suitable for this standard.
■Hysteresis Curve
The fixed input gear is applied to the output to obtain the corresponding relationship between the torque and the torsion angle, and the hysteresis curve is drawn. (Figure 1)
■Transmission Accuracy
Transmission accuracy (θ): refers to the input with arbitrary rotation angle when the theory of rotation angle (θin) and the actual output rotation angle (θout) between poor and formula: θ=θin/k-θout (k—Ratio values).
■Backlash
The intermediate point of the hysteresis curve of the nominal torque of 3%. (Figure 1)
■Backlash
Torsion angle at the rated torque of zero. (Figure 1)
■Torsional Stiffness
Torsional stiffness = B/A. (Figure 1)
•Figure 1 — Hysteresis curve Unit: (Nm/arc min)
■New Main Bearing Rigid Definition:
Moment rigidity
When subjected to an external load moment, the output shaft is tilted in proportion to the load moment, resulting in an angle 0 (N'm/arc.min).
θ=(W1︱1-W2︱3)/(Mt X 103) Mt is the bending stiffness (As shown).
Bending stiffness represents the stiffness of the main bearing, expressed in terms of the load torque required for a unit angle of inclination (1 arc.min).
