Bonfiglioli EVOX platform CP coaxial helical gear reduction motor

​General Fundamentals and Environmental Constraints

1.1 Environmental working conditions

temperature

Gearbox: Standard environment -25 ℃~+50 ℃; Contact technology is required for temperatures below -25 ℃ or above+50 ℃; Start with partial load at -25~-10 ℃ to avoid gear damage from cold start impact.

EVOX motor standard operating temperature -15 ℃~+40 ℃; Power derating at temperatures above 40 ℃: 97% at 45 ℃, 94% at 50 ℃, 90% at 55 ℃, and 86% at 60 ℃.

elevation

Reference condition altitude<1000m; output power derating for altitude>1000m;

If the altitude change is greater than 1000m, and the factory pre fills the oil, it is necessary to open the oil drain plug to balance the pressure inside and outside the housing to prevent oil leakage caused by abnormal internal pressure.

Noise and vibration: The noise test of the gearbox is based on UNI ISO 3746; The motor complies with CEI EN 60034-9; The noise of the gearbox is usually lower than that of the matching motor.

Storage requirements

Prohibit outdoor storage in damp conditions, and elevate equipment off the ground;

Apply rust inhibitor to the processing surface (flange, shaft extension); Long term storage requires oil injection and replacement of ventilation plugs with closed plugs; Restart and add the correct grade of lubricating oil.

Efficiency: Coaxial helical gears have an efficiency of approximately 0.98 per stage, with 2nd stage ≈ 0.96 and 3rd stage ≈ 0.94.

1.2 Complete selection input parameter table

Before selection, a complete set of operating conditions must be collected for calculation and verification. Key parameters include output power (P_ {r2}), output torque (M {r2}), and input/output speed (n1/n2); Input/output shaft radial load \ (R_ {c1}/R_ {c2} \), load action distance \ (x_1/x_2 \); Axial load \ (A_ {c1}/A_ {c2} \); Load inertia \ (J-c \); Environmental temperature and altitude; Work schedule S1-S9; Hourly startup frequency \ (Z_r \); Motor voltage, brake torque, protection level, insulation level.

1.3 Service Factor Calculation

The service coefficient depends on three factors: load shock level K, number of starts per hour (Z_r), and daily operating hours

K1 uniform load \ (K \ le0.25 \);

K2 moderate impact (0.25<K \ le3 \);

K3 strong impact (3<K \ le10 \);

K＞10， It is necessary to contact the manufacturer for evaluation and not directly apply charts.

Calculate the torque \ (M2=M2 × SF \), select the gearbox to ensure the rated output torque \ (M2 \ ge M2 \).

Work system correction: S2 short-term and S3 intermittent cycle work system, with a default cycle of 10 minutes, using \ (f_m \) power amplification factor.

1.4 Selection verification items

Mechanical capacity verification;

Thermal capacity verification: When the altitude is less than 3000m and the environment is less than 50 ℃, thermal power generally does not become a bottleneck; Beyond this range, thermal verification must be conducted;

External load verification of the shaft (radial load, axial load).

1.5 Radial Load Calculation Formula and Position Correction

\(R {c}=\ frac {2000 \ cdot M {a} \ cdot K {r} {d} \) Sample allowable radial load reference condition: the load application point is at the midpoint of the axis extension. The load is offset towards the axis end, requiring geometric conversion \ (R_a=R_ {max} \ frac {l1} {l2+x} \), and the converted \ (R_a \) must be greater than the actual calculated load \ (R_c \).

Simultaneously bearing radial and axial composite loads, it is necessary to submit a Bangfeili technical evaluation.
