What are the technical parameters of RF87-NA45-Y112-D340 reducer

The core technical parameters of RF87-NA45-Y112-D340 reducer are as follows:

1、 Model meaning disassembly

RF87: R series helical gear hard tooth surface reducer, F=flange installation, 87=machine base number (medium size)

NA45: Hollow shaft output, shaft diameter φ 45mm (with locking disc/expansion sleeve)

Y112: Compatible with IEC standard Y series motors, frame number 112 (commonly 4-pole, power approximately 4kW)

D340: Center distance/installation distance 340mm (or flange installation size code)

2、 Core Performance Parameters (RF87 Series Universal+Model Corresponding)

Suitable motor: Y112 base, 4P (1450r/min), approximately 4kW standard three-phase asynchronous, can be equipped with variable frequency/brake/explosion-proof

Reduction ratio range: single machine: 1.39-246.54; Commonly used: 3.33/5.3/7.13/13.33/27.84/47.58/93.38 two-stage/three-stage transmission, which can be combined with larger speed ratios

Output speed: approximately 5.9-1045r/min (input at 1450r/min). The higher the speed ratio, the lower the speed and the greater the torque

Output torque: approximately 500-1550N · m (RF87 series) with hard tooth surface (HRC58-62), strong load-bearing capacity and impact resistance

Transmission efficiency: two-stage ≈ 96%, three-stage ≈ 94%. The helical gear mesh has low energy consumption and minimal heat generation

Installation form: flange installation (F), compact horizontal/vertical universal structure, saves space

Output shaft: Hollow shaft NA45 (φ 45mm), with locking disc shaft installation, directly fitted onto the working shaft, easy to disassemble and assemble

Center distance/installation distance: D340 (340mm) determines the installation space and axis extension fit size

Protection level: IP55 (standard) dustproof, splash proof, suitable for industrial environments

Noise: 65-75dB (A) Precision grinding, smooth operation, low noise

Lubrication: VG220/320 industrial gear oil for lifelong lubrication or regular replacement, easy maintenance

Material: Box body: HT250/ductile iron; Gear: 20CrMnMo (carburized and quenched); Axis: 42CrMo High strength, wear-resistant, long life
