Product Description:

Integral Brake Motors are suitable for various industrial application like Textile, Machine
Tools, Hoists, Cranes, Lifts etc., where instantaneous stopping of the driven equipment is
demanded.

Motors are fitted with Electro Mgnetic Normally on brakes.

The electro-magnetic DC brake is mounted on the non-driving end of the motor. The cooling
fan is mounted after the brake for better thermal dissipation and cooling of the brake also.

Motor connection leads and brake coil leads are terminated in a single terminal box for
easy connection, Rectifiers are supplied in loose condition and Manual release is provided

Versatile Mounting and Design

The NMRV 40 Gear Box can be universally mounted with either foot or flange options, offering flexibility for various layouts and machinery types. Its compact and robust aluminum body resists corrosion, while the hardened steel gears deliver consistent torque. Precision machining ensures a long service life and minimal maintenance.

High Performance and Efficiency

Engineered for demanding applications, this worm gearbox achieves efficiency up to 85% and maintains output torque of up to 21 Nm. The gear ratios ranging from 7.5:1 to 100:1 allow you to select the perfect configuration for speed and torque requirements, increasing productivity and reliability in conveyance or packaging systems.

Operational Reliability in Diverse Environments

Operating smoothly within -15C to +40C, and protected with IP55 (when connected to a suitable motor), the gearbox endures dust, moisture, and temperature variations. Synthetic oil lubrication reduces wear, ensuring quieter operation at just 60 dB and extending maintenance intervals in rugged settings.

FAQ's of NMRV 40 Gear Box:

Q: How do I select the appropriate gear ratio for my application using the NMRV 40 Gear Box?

A: To choose the right gear ratio, consider the required output speed and torque for your machinery. The NMRV 40 supports ratios from 7.5:1 to 100:1, allowing you to control the output speed between 14 and 186 rpm. Match the ratio to your application's speed and torque requirements for optimal performance.

Q: What mounting positions are available for the NMRV 40, and how do I install it?

A: The NMRV 40 supports universal mounting, which means you can use either foot or flange mounting as needed. Installation involves securing the gearbox with bolts through the designated holes on the flange or foot, attaching it to your machinery's frame or surface.

Q: When should I perform maintenance on the NMRV 40 Gear Box, and what does it involve?

A: Regular checks are recommended, especially on lubrication levels and gear performance. Since the gear box is lubricated with synthetic oil, periodic inspection is essential for continuous smooth operation. Maintenance intervals may extend due to efficient lubrication and robust construction.

Q: Where is the NMRV 40 Gear Box commonly used?

A: This gearbox is commonly utilized in conveyors, packaging equipment, mining operations, and agricultural machinery, thanks to its versatile mounting, reliable torque delivery, and protective features.

Q: What benefits does the NMRV 40 Gear Box offer over traditional gearboxes?

A: It provides multiple mounting positions, high efficiency (up to 85%), quieter operation at 60 dB, reversible direction, and reliable operation in a wide temperature range. Its precise machining and synthetic lubrication result in lower maintenance and longer service life.

Q: How does the IP55 protection class benefit my application when using the NMRV 40?

A: With a compatible motor, the IP55 rated gearbox resists dust and water ingress, ensuring reliable performance even in challenging environments such as agricultural or mining sites.

Q: What process should I follow to couple the NMRV 40 Gear Box with a motor?

A: Choose a motor with compatible shaft sizes (input 11mm), suitable rated power (0.18-0.37 kW), and appropriate voltage (220V/380V). Securely attach the gearbox to the motor flange, ensuring precise alignment to maximize efficiency and reduce vibrations.
