WA37B-AQH80 is a high-performance right-angle gear unit produced by SEW-EURODRIVE. It adopts advanced SPIROPLAN gearing design, featuring compact structure, low running noise and excellent durability. This product is widely applied in conveyor systems, packaging machines, food processing equipment and various industrial automation facilities.

WA37B represents a SPIROPLAN right-angle gear unit in frame size 37, designed for base mounting with hollow output shaft. AQH80 indicates the input flange configuration, which is compatible with IEC frame size 80 standard motors.

All installation, commissioning and maintenance work must be carried out by qualified technicians. Disconnect the power supply completely before performing any maintenance or disassembly. Never operate the gear unit beyond its rated torque and speed limits. Protect the unit from severe impact, corrosive substances and heavy dust. This gear unit is pre-filled with long-service-life lubricant at the factory. Do not disassemble the unit arbitrarily. Ensure reliable and firm mounting to prevent abnormal vibration during operation.

This 90-degree right-angle gear unit delivers a maximum output torque of 110 Nm. The available gear ratio ranges from 3.20 to 69.05. The input flange is tailored for IEC 80 motors, and the standard output type is hollow shaft. The overall protection class is IP54.

The housing is made of cast aluminum alloy, which is lightweight and offers efficient heat dissipation. The total weight of the gear unit is approximately 12 kg. Multiple mounting options including base mounting and flange mounting are available. The operating ambient temperature ranges from -10 °C to +40 °C.

Fix the gear unit on a flat and rigid foundation. Tighten all mounting fasteners securely to avoid loosening caused by operating vibration. Select a suitable installation orientation according to the site layout. Reserve sufficient surrounding space for heat dissipation and daily inspection.

Align the IEC 80 motor with the AQH80 input flange accurately. Fasten the motor with standard fasteners and guarantee good coaxiality. Avoid applying extra radial or axial loads to the shaft end. Double-check all connections before trial operation.

Perform a no-load test run after completing installation. Keep the unit running for several minutes and check for abnormal noise, vibration or oil leakage. Apply load gradually only after confirming stable no-load operation.

Operate the gear unit strictly within the rated working range. Avoid frequent start-stop cycles under full load for extended periods. Stop operation immediately once abnormal noise, overheating or fluid leakage is detected, and conduct thorough inspection.

The gear unit is filled with lifelong lubricant during production and requires no regular oil replacement. Inspect the tightness of mounting screws and check for oil leakage every six months. Clean surface dust with a dry cloth. Do not wash the unit with high-pressure water. Contact the official service team for professional repair if internal faults occur.

Abnormal running noise is generally caused by loose mounting, poor coaxial alignment or overload operation. Oil leakage usually results from damaged sealing components. Excessive vibration may be caused by loose fasteners or unbalanced load. Shut down the equipment and resolve faults timely.
