AR28688 | RTD Reduction Gear Box, 1:1.86 Ratio Drive

AR AR28688 RTD Reduction Gearbox – 1:1.86 Ratio

Overview

The AR AR28688 RTD Reduction Gearbox (1:1.86) is a heavy-duty, precision-engineered
drive component from Annovi Reverberi. It delivers smooth torque conversion, efficient power
transmission, and long-term reliability in continuous-duty industrial and commercial pump systems.

• Reduces high input RPM to optimal pump speed.
• Increases output torque for stronger pump performance.
• Engineered for continuous-duty wash, agricultural, and hydraulic systems.
• Designed for quiet, low-vibration operation.

1:1.86 Reduction Ratio & Performance

The 1:1.86 ratio is selected to balance engine/motor speed with pump requirements.

• Allows high-RPM engines (e.g., ~3400 RPM) to drive pumps at ideal operating speed.
• Increases torque at the pump shaft, improving startup and load handling.
• Reduces risk of over-speeding, cavitation, and excess wear on the pump.
• Supports consistent flow and pressure across varying system loads.

Housing & Structural Design

The AR28688 gearbox housing is built for strength, alignment, and heat control.

• High-strength cast aluminum or steel alloy body for rigidity and long life.
• Excellent corrosion resistance for outdoor and industrial environments.
• Engineered to resist deformation under high torque loads.
• Smooth, contoured case promotes heat dissipation during long duty cycles.

Hardened Helical Gear Set

Internally, the gearbox uses helical gearing for smooth, efficient torque transfer.

• Hardened, precision-ground helical gears for high torque capacity.
• Gradual tooth engagement minimizes shock, vibration, and noise.
• Even load distribution across gear teeth reduces wear and extends service life.
• Improves overall energy efficiency compared with straight-cut gears.

Sealed Oil-Bath Lubrication

A sealed lubrication system protects the gearing and bearings.

• Continuous oil bath lubrication reduces friction and heat build-up.
• Sealed housing keeps out dust, water, and chemicals.
• Oil sight glass allows quick visual level checks.
• Vented fill cap and drain plug simplify scheduled oil changes.

Bearings & Shaft Sealing

Heavy-duty bearing and seal systems maintain alignment and prevent leaks.

• Robust bearings support input and output shafts under dynamic loads.
• Precision seating for low friction and smooth rotation.
• Advanced synthetic shaft seals withstand pressure, temperature, and chemical exposure.
• Stable, leak-free performance even in continuous-use service.

Mounting, Shafts & Integration

The gearbox is built for easy coupling to engines and AR pumps.

• Precision-machined input and output shafts for accurate coupling.
• Direct-mount flanges minimize adapters and simplify installation.
• Compact, balanced design fits both stationary skids and mobile rigs.
• Direct-drive configuration reduces vibration and power loss.

Typical Applications

• High-pressure cleaning rigs and industrial wash plants.
• Agricultural spraying and equipment washdown systems.
• Hydraulic power units requiring speed reduction and torque boost.
• Continuous-duty pump systems where smooth, quiet operation is critical.

Maintenance & Service

The AR28688 is designed for simple, low-frequency maintenance.

• Periodic oil checks via sight glass and scheduled oil changes.
• Sealed case limits contamination, reducing service needs.
• Corrosion-resistant materials and finishes withstand harsh environments.
• Only occasional inspection of seals, fasteners, and oil level is typically required.

Quality & Reliability

• Each unit tested for dimensional accuracy, noise level, and torque efficiency.
• Built to Annovi Reverberi’s industrial-grade standards for professional equipment.
• Italian-engineered for precision, durability, and repeatable performance.

Summary

The AR AR28688 RTD Reduction Gearbox – 1:1.86 ratio combines hardened helical gears,
a rigid cast housing, sealed oil-bath lubrication, and precision-balanced bearings to deliver
optimal torque control and quiet, vibration-free performance. Ideal for pressure washing,
agricultural, and hydraulic drive systems, it improves pump efficiency, protects critical
components, and provides years of dependable service in demanding industrial conditions.
