- Special flange interface (F1 type): Optimize flange size and bolt hole position, adapt to servo motors, stepper motors and general asynchronous motors, and reduce the need for installation adapters.
- Modular expansion: Supports multi-stage series or parallel configuration, and flexibly expands transmission ratio and output torque.
- Lubrication design: Built-in long-lasting grease (optional food-grade lubricant), suitable for clean environments.
Industrial automation: Robotic arm joint drive, automated assembly line, precision positioning platform.
- New energy equipment: Photovoltaic tracking bracket adjustment, wind power generation variable pitch system.
- Medical equipment: CT machine rotation mechanism, surgical robot transmission module.
- Food processing: Aseptic filling machine, mixing tank drive, packaging machinery power transmission.
- Railway transportation: Platform safety door drive, carriage ventilation system adjustment.
1. High-precision transmission
- The meshing clearance of the worm gear is adjustable (≤0.05mm), suitable for precision positioning control.
2. Enhanced sealing performance
- Double lip oil seal + labyrinth seal structure to prevent grease leakage and external contaminants from intruding.
3. High temperature resistant design
- The housing is made of ADC12 aluminum alloy die-casting, with excellent heat dissipation performance and supports short-term high-temperature operation.
4. Low backlash and high rigidity
- The output shaft is quenched and tempered, and the radial load capacity is increased by 20%, which is suitable for heavy-load swing scenarios.
5. Intelligent compatibility
- Optional encoder interface or brake module can be used to meet the closed-loop control requirements of the servo system.
6. Green and energy-saving
- Optimized tooth design reduces friction loss, and the comprehensive energy efficiency ratio is increased to more than 90%.
7. Safety redundancy
- Double self-locking function (mechanical self-locking + optional electromagnetic brake) to ensure the safe parking of vertical loads.
The technical process of worm gear reducer integrates the three core advantages of high-strength materials, precision processing, and modular design. Through carburizing and quenching, CNC gear grinding, double seal structure and other innovative processes, it achieves a balance between high precision, high reliability and environmental adaptability. Its process cost is relatively high, but it is suitable for industrial scenarios with strict performance requirements, such as automation, new energy and medical equipment.

The company's products are sold well throughout the country and exported to Europe, America, the Middle East, South Asia and Australia. After years of rapid development, the company has become a backbone enterprise of Hangzhou's "Hometown of Reducers", specializing in the research and development, production and sales of NRV-VS-F1 worm gear speed reducers.
1. Core technical advantages of NRV-VS-F1 worm gear reducer
This product uses high-quality aluminum alloy shell, which has the characteristics of beautiful, lightweight, and never rusting. It is widely used in light industry, chemical industry, food, packaging, glass machinery, ceramics, pharmaceuticals and other industries, as well as various production automation lines, conveyor lines, assembly lines, etc. that require speed regulation.
2. Transmission efficiency optimization design
Precise meshing of worm and gear: high-precision grinding technology is used to ensure close meshing between the worm and the worm wheel, reduce friction loss, and improve transmission efficiency (usually up to 90% or more).
Low backlash design: optimize the matching of gear pairs, reduce the return clearance, and is suitable for automation equipment with high-precision positioning requirements.
Lubrication technology: high-performance grease or oil bath lubrication is used to reduce operating temperature rise and extend service life.
3. Self-locking characteristics and their applications
One-way self-locking function: the special helix angle design of the worm and gear enables the worm to drive the worm wheel, but the worm wheel cannot reversely drive the worm, which is suitable for anti-reversal scenarios (such as elevators, conveyor belts, etc.).
Safe and reliable: in the event of power failure or emergency shutdown, the self-locking function can prevent the load from sliding down and improve the safety of the equipment.
Applicable industries: food packaging machinery, automated assembly lines, glass production lines, etc., where precise positioning + anti-retraction is required.
