I. Product Overview
The RV series is a compact worm‑gear reducer with an aluminum alloy housing, featuring a worm‑and‑wormwheel transmission design. It offers self‑locking capability, low noise, and high transmission efficiency, making it widely used in industrial automation, material handling equipment, packaging machinery, and other applications—making it a classic gear‑reduction solution for small and medium‑sized equipment.
II. Core Structure and Characteristics
1. Structure and Material
- Shell : Aluminum alloy die-cast housing—lightweight, excellent heat dissipation, and corrosion-resistant, making it suitable for humid or light‑industrial environments.
- Transmission components The worm is made of 20CrMnTi steel, case‑hardened and quenched to a surface hardness of 56–62 HRC; the worm wheel is crafted from tin bronze, offering excellent wear resistance, smooth transmission, and low noise.
- Installation type : Supports multiple mounting options, including flange-type input/output and base‑mounting, to accommodate diverse equipment installation requirements.
2. Performance Characteristics
- Self-locking function : Worm gear drives feature reverse self-locking, preventing the load from rotating in the opposite direction and enhancing equipment safety.
- Efficiency and Noise : Optimized tooth profile design, high transmission efficiency, low operating noise, and suitable for continuous long-term operation.
- Protection rating : Standard IP54 protection, dust‑ and splash‑proof, suitable for dusty and humid workshop conditions.

Exploded View of the Part
The core components include the worm, worm gear, bearings, end covers, oil seals, adjusting shims, and the housing, featuring a compact structure and convenient maintenance.
IV. Selection and Application
1. Selection Guide
- Power and torque matching : The selection shall be based on the load power, speed, and torque requirements, in conjunction with the service factor (Fs), according to the following formula:
P₁ ≥ P₂ × Fs(P₁ is the input power of the reducer, and P₂ is the load power.) - Operating Condition Factor Adjustment : Select the service factor based on the load type (uniform / moderate / impact) and the daily operating duration (2 h / 8 h / 16 h / 24 h); for impact loads, the service factor should be appropriately increased.
- Rotational speed limit Standard input speed ≤ 1500 rpm; the output speed decreases as the reduction ratio increases, with higher reduction ratios yielding greater output torque and lower output speed.
2. Typical Application Scenarios
- Industrial Automation: Conveyor Systems, Packaging Machinery, Food Processing Equipment
- General-purpose equipment: small machine tools, water pumps, fans, and mixers.
- Light industrial equipment: textile machinery, printing equipment, and auxiliary power for automated production lines.
V. Supplementary Notes
The RV series gear reducers support a variety of surface finishes—standard RAL 5010 blue or white—and can also be customized to meet specific customer requirements for mounting interfaces, shaft diameters, and reduction ratios, thereby accommodating a wide range of equipment needs.
