NMRV Aluminum Worm Gear Box

Product Overview

NMRV series aluminum worm gearbox (NMRV Aluminum Worm Gear Box) adopts lightweight aluminum alloy casting process and precision worm-bronze worm gear meshing technology, with a rated output torque of 1.3N·m879N·m, suitable for 0.06kW-15kW motor power. This series of Aluminum Worm Gear Box takes right-angle transmission and efficient heat dissipation as its core advantages. It is designed for food machinery, automated assembly lines, medical equipment and other space-constrained and frequently started and stopped scenes. It has an IP55 protection level and can operate stably in -15℃80℃ environment.

Product Features

Lightweight aluminum alloy structure

The weight of the chassis is 40% lighter than that of cast iron, the heat dissipation efficiency is increased by 25%, and the surface is anodized for corrosion resistance.

Precision worm gear pair design

The surface carburizing and quenching hardness of the worm reaches HRC50±2, and the worm wheel uses SNB8 tin bronze, with a transmission efficiency of ≥85%.

Compact right-angle output

The modular design saves 60% of the installation space, and the right-angle tolerance of the input/output shaft is ±0.1°.

Lifetime maintenance-free lubrication

Pre-filled with high-grade lithium-based grease (ISO VG220), oil seal life ≥ 20,000 hours.

Silent and low vibration

Gear meshing accuracy reaches ISO grade 8 standard, operating noise ≤ 58dB (tested at a distance of 1 meter).

Product advantages

Medical equipment: CT scanning bed lifting mechanism, blood separator transmission

Environmental protection field: intelligent garbage sorting device, sewage treatment valve control system

FAQ Technical Questions and Answers

Q1: Does the aluminum alloy box affect the load capacity?

Through topological optimization design, the compressive strength reaches 180MPa, which can withstand 3 times the instantaneous overload impact.

Q2: How to extend the service life of the worm gear?

Avoid long-term full-load operation (recommended load rate ≤ 80%), and clean the heat sink dust every six months.

Q3: Does it support direct connection of servo motor?

Provide IEC 100L-4 flange interface version, matching 0.75kW servo motor (flexible coupling required).

Q4: Grease replacement cycle and operation method?

Lifetime maintenance-free design, it is recommended to add grease every 5 years under extreme working conditions (original SN-C320 grease must be used).
