NMRV-VS Dual Input Worm Gearbox with IEC Motor Flange
Deskripsi Produk
- Quick stop function
For a general gear reducer, it takes 5 to 10 seconds for the stop time, but for the NRV series, the stop state could be reached in only 2 to 5 seconds. - High safety
The NRV worm gearbox adopts a different way compared with the traditional 1 in that it doesn’t need the sprocket and pulley. What’s more, the transmission structure is not exposed so that injuries to the operator could be reduced. - Good protection
Grade IP55 is adopted which has good isolation for dust and moisture. - Excellent thermal conductivity
The NRV worm gear is equipped with cooling CHINAMFG so that the body has excellent thermal conductivity and low temperature-rising. - Long service life
The worm gearbox operates smoothly with low noise which is suitable for long-term contact work in harsh environments.

Penggunaan Gearbox NMRV pada Aplikasi Beban Tinggi
Gearbox NMRV dapat digunakan dalam aplikasi beban sedang hingga tinggi, tetapi kapasitas bebannya umumnya terbatas dibandingkan dengan beberapa jenis gearbox lainnya. Gearbox ini paling cocok untuk aplikasi dengan beban ringan hingga sedang, seperti sistem konveyor, peralatan pengemasan, dan mesin kecil. Penting untuk mempertimbangkan persyaratan beban spesifik dan berkonsultasi dengan produsen atau insinyur gearbox untuk memastikan gearbox NMRV yang dipilih dapat menangani tuntutan beban aplikasi yang dimaksud.
Pelumasan untuk Kotak Gigi NMRV
Pelumasan sangat penting untuk fungsi yang tepat dan umur pakai yang panjang dari gearbox NMRV. Jenis dan jumlah pelumas yang dibutuhkan dapat bervariasi tergantung pada model dan pabrikan gearbox. Berikut adalah praktik pelumasan umum:
- Pelumas yang Direkomendasikan: Gunakan pelumas yang ditentukan oleh pabrikan gearbox. Biasanya, oli gearbox berkualitas tinggi dengan viskositas dan aditif yang sesuai direkomendasikan.
- Pengisian Awal: Sebelum pengoperasian pertama gearbox, pastikan gearbox terisi dengan pelumas yang direkomendasikan hingga level yang tepat. Ikuti panduan pabrikan untuk jumlah yang tepat.
- Penggantian Pelumas: Ganti pelumas secara teratur sesuai dengan interval yang direkomendasikan oleh pabrikan. Seiring waktu, pelumas dapat mengalami degradasi akibat panas dan kontaminasi, yang dapat memengaruhi kinerja gearbox.
- Pertimbangan Suhu: Kotak roda gigi yang beroperasi pada suhu ekstrem mungkin memerlukan pelumas dengan rentang suhu spesifik untuk memastikan viskositas dan perlindungan yang tepat.
- Memeriksa Level: Periksa secara berkala level pelumas di dalam gearbox untuk memastikan berada dalam kisaran yang ditentukan. Hal ini dapat mencegah kerusakan yang disebabkan oleh pelumasan yang tidak memadai.
- Analisis Oli: Beberapa sistem transmisi mendapat manfaat dari analisis oli secara berkala untuk memantau kondisi pelumas dan mengidentifikasi potensi masalah sebelum menyebabkan kerusakan yang signifikan.
Praktik pelumasan yang tepat berkontribusi pada pengurangan gesekan, keausan, dan pembangkitan panas di dalam gearbox NMRV, sehingga meningkatkan efisiensi dan memperpanjang umur pakai.
Working Principle of an NMRV Gearbox
An NMRV gearbox, also known as a worm gear reducer, operates based on a worm and worm wheel mechanism. Here’s how it works:
The gearbox consists of two main components: the worm (a screw-like shaft) and the worm wheel (a toothed wheel). The worm is driven by the input power source, while the worm wheel is connected to the output shaft.
As the worm rotates, its threaded shaft engages with the teeth of the worm wheel. The helical shape of the worm causes the teeth of the worm wheel to push against each other, resulting in a smooth and gradual transfer of motion. This mechanism provides the speed reduction and torque multiplication required for various applications.
One key characteristic of NMRV gearboxes is that the worm can turn the worm wheel, but the reverse is not possible due to the high friction generated by the helical threads. This feature prevents the output shaft from back-driving the input shaft, providing mechanical locking and enhancing safety and stability in applications.
The NMRV gearbox’s operation is continuous, and its simple design contributes to its reliability and efficiency. It is important to ensure proper lubrication to minimize wear and heat generation during operation.
