RV30/ RV40/RV50/RV63/RV75 /90/RV110/RV130 Nmrv Worm Gear Reducer

Product Description

Product Description

       

          As a professional manufacturer of industrial precision transmission equipment, we focus on the R&D, production and customization of precision planetary gearboxes, helical planetary reducers, helical geared motors, and helical-worm gear reducers. Covering mainstream series such as PL, PX, PAIIR, S, R, and RX, our products fully serve automated equipment, intelligent machinery and industrial drive systems, solving the core pain points of low precision, loud noise, poor stability and short service life of traditional reduction equipment for global industrial customers.

     
       All series of our reducers adopt high-precision gear grinding technology and integral alloy steel heat treatment process. The core gear components feature high hardness, strong wear resistance and excellent impact resistance. The optimized helical tooth meshing structure achieves ultra-smooth transmission, effectively reducing vibration and noise during high-frequency start-stop and long-term continuous operation. Our precision planetary gearboxes support ultra-low backlash control from ≤1arcmin to ≤15arcmin, with transmission efficiency up to 88%-97%, perfectly matching servo motors and stepper motors of different specifications (60/90/110/130 servo frame, 57/86 stepper frame, 400W-1.5KW geared motors), covering full-speed-ratio and full-size application requirements.

     
     We adhere to high-standard industrial manufacturing and strict quality inspection systems. The whole machine adopts fully sealed permanent lubrication design, realizing lifetime maintenance-free operation and greatly reducing later operation and maintenance costs for customers. With IP54/IP65 high protection grade, the equipment can operate stably in complex working conditions such as high and low temperature, dust and humidity, featuring strong environmental adaptability and a standard service life of up to 20,000 hours. Modular and diversified structural design supports multiple installation methods, solid/hollow shaft output and non-standard customized development, which can perfectly adapt to robotic arms, AGV vehicles, CNC machine tools, packaging machinery, textile equipment, logistics conveying systems and various industrial automation production lines.

Packaging & Shipping

Packaging

• Each motor is wrapped with plastic film for dust and moisture protection.
• Front & rear foam cushions provide shock absorption to prevent impact damage.
• Reinforced printed export corrugated carton serves as outer packaging.
• Custom packaging options are available.

Transportation

• Sea Transport: 20ft / 40ft shipping containers for international delivery.
• Road Transport: Palletized cargo delivered by trucks for domestic & overland transport.
• Rail Transport: Motors packed in cartons, stably secured on pallets for railway shipment.

Handling Precautions

• Prevent moisture ingress to avoid rust and insulation deterioration.
• Secure all cartons and pallets to avoid displacement during transport.
• Avoid prolonged exposure to extreme temperatures.
• Adopt proper handling machinery; never hoist the motor by the shaft or terminal box.
• Observe carton stacking restrictions to avoid compression damage.
