Product Introduction

Reliance 352066-CA is a dual-stage reduction drive unit specifically designed for screw conveyors, under the brand of Baldor-Reliance. It belongs to the SCXT225A series of drive units and is compatible with shaft-mounted reducers for screw conveyors. It is mainly used in industrial heavy-load and continuous operation scenarios. The original factory has discontinued production, and now it is mostly circulated as refurbished or second-hand spare parts.

Interface and communication configuration

Power interface: Standard motor flange interface, compatible with corresponding power three-phase motor.

Output interface: Hollow shaft output, with key slot, matching the conveyor main shaft.

Auxiliary interface: Reserved position for speed sensor installation, oil level observation window, oil drain port.

Communication configuration: No built-in communication interface, pure mechanical transmission unit, can be externally connected with speed sensor for secondary instrument monitoring.

Core functions

Two-stage reduction: High reduction ratio design, output large torque, suitable for conveyor's low-speed heavy-load requirements.

Stable transmission: Precise gear meshing, smooth operation, low noise, reducing material conveying fluctuations.

Heavy-duty durability: Cast iron housing + reinforced gears, shock-resistant, wear-resistant, suitable for 24-hour continuous operation.

Maintenance-free design: Long-lasting lubrication system, sealed structure prevents oil leakage and dust intrusion.

Simple installation: Shaft-mounted structure, no need for complex base, align the main shaft to fix. Applicable scenarios

Bulk material transportation: driven by screw conveyors for grains, cement, chemical powder, ore powder, etc.

Light industry / construction materials industry: material transportation lines for mixing stations, feed mills, chemical plants, and cement plants.

Heavy-duty continuous operation: industrial conveyor equipment that needs to operate 24 hours a day and has high torque output.

Equipment retrofit: replace the old series of outdated drive units and adapt to the existing installation dimensions of the conveyors.

Operation and maintenance instructions

Installation: Clean the main shaft and hollow shaft before fixation, apply anti-clogging agent; align the key slots and evenly tighten the flange bolts to avoid uneven loading.

Lubrication: Replace the gear oil after the first 200 hours of operation; replace it every 3000 hours or every half a year under normal conditions, keep the oil level at the center line of the observation window.

Operation inspection: Check for abnormal sounds, oil leakage, and abnormal vibrations daily; tighten the bolts monthly and inspect the wear of the sealing components.

Maintenance prohibitions: Do not operate with insufficient oil, do not start under overload, do not open the cover for inspection during operation.

Safety regulations: Before maintenance, cut off the power supply of the upstream motor, wait for the gears to completely stop before operating; regularly check the integrity of the coupling and protective devices.
