The worm geared motors contain worm gear reducer and motor (Including three phrese AC motor, single phase AC motor, DC servo motor and DC PM motor). During the process, many advanced technologies are adopted. So it has compact structure, good appearance and excellent heatsink when runing. This series worm drive motor has the following characteristics: smooth running, low noise, large transmission ratio and strange load capacity and it may match with different kinds of motors for realizing speed adjustment.

* NRV075: Single Solid Shaft Worm Gearbox.

NRV worm gearbox is generally with a single input shaft, and there are also double input shaft forms, suitable for various transmission needs. The output forms include hollow hole output and flange output. 

* NRV075-F: Single Solid Shaft Input with Square Flange Output.

NRV-F worm gearbox is a worm gear reducer with shaft input and square flange output. Different models of RV worm reducers have different flanges, which can be docked with matching flange-type shaft holes. The standard output flange is a short output flange (FA), and a long output flange (FB) is also available.

* NRV075-VS: Dual Solid Shafts Input Worm Gearbox with Flange Output.

NRV-VS worm gearbox is an RV worm gear reducer that has the input solid shaft with extension, a double input form. The main function is to facilitate the use of additional accessories such as hand-cranking devices and encoder speed measurements for customers, and it can also realize the combination of multiple reducers.

* NMRV075: Worm Gearbox with Flange Output.

NMRV Aluminum Worm Gearbox with Output Flange. NMRV worm gearbox is equipped with high-quality aluminum alloy casting and it adopts the advanced square box structure which is small in size, light in weight, and beautiful in appearance. The worm gear reducer could be matched with other gearboxes to reach a large ratio and torque. What's more, due to the small size of the gearbox, it is easy to install and maintain.

* NMRV075-F: Worm Gearbox with IEC Motor Flange.

NMRV…F worm gearbox is extremely convenient to connect with ordinary motors, continuously variable transmissions, and flanged electromagnetic clutch brakes and does not require couplings to connect. It can be installed in all directions, and the output method is flange output, which can be connected to the shaft hole of the matching flange type. The output flange standard is a short output flange ( FA), and a long output flange (FB) is also available.

* NMRV075-VS: Dual Input Worm Gearbox with IEC Motor Flange.

NMRV-VS worm gearbox is a dual-input mode, one side can be connected with an ordinary motor, stepper motor, stepless speed changer, or flanged electromagnetic clutch brake group, no coupling is needed to connect, and the other side can be connected with a coupling or shaft hole, which can achieve more than 2 sets of equipment synchronization job. NMRV-VS worm gearbox is a hollow shaft output type, which can be directly connected to the solid shaft of the equipment or the output shaft with accessories.

* NMRV-NMRV: High Torque Double Stage Worm Gear With IEC Motor Adaptor.

NMRV and NMRV gearbox that can be equipped with various input and output forms and is also available to customize according to the actual installation requirements like the flange installation size, the length or size of the output shaft and other specifications. Double worm gear reducer can increase torque more through two worm gears. Double reduction worm gearbox has the characteristics of transmission balance, low-temperature rise, low noise, high efficiency, and long service life due to the precision machining of the worm gear and strict gear transmission test.

* NRV-NMRV: Double Stage Worm Gear With Input Shaft.

An NMRV/NRV worm gearbox motor reducer offers a cost-effective solution and lightweight. The NMRV/NRV worm gear reducer is compatible with both NEMA and IEC motor flanges. The NMRV worm gear motor reducer offers low lifting speed and high torque while being available in a variety of models.

* PC-NMRV: Worm Gearbox with Pre-stage Helical Gear Unit.

PC means the helical Pre-stage unit. The PC+NMRV worm gearbox adopts an advanced square box structure, and the shell is made of high-quality aluminum alloy die casting, and it has lightweight and has no rust. What's more, it has good heat exchange performance and fast heat dissipation, which guarantee the high efficiency and long service life of the worm gear motor. Besides, it could mount with a square flange and round flange to match various types of motors.
