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).

LUBRICATION

 

■Reducer using lubricating oil: Molywhite RE-00 or VIGO- grease REO other similar grade precision reducer special grease

■The lubrication grease is not filled before gearbox leave factory. Please fill in the suggested lubrication grease during assembly, the amount is roughly 90% of the gearbox inside cavity volume

■Lubricating grease standard replacement time is 20000 hours. When the grease is contaminated or is used in harsh environment, it is necessary to check the condition of aging and pollution, and to change the time
