EP-NMRV Worm Gear Reducer with Output Flange \u2014 Flange Series, Models 030\u2013150<\/h2>\n
\n
\n

The EP-NMRV \u0e40\u0e01\u0e35\u0e22\u0e23\u0e4c\u0e17\u0e14\u0e23\u0e2d\u0e1a\u0e41\u0e1a\u0e1a\u0e2b\u0e19\u0e2d\u0e19<\/strong> with output flange is a compact aluminium alloy speed reduction unit available in nine standard centre distances from EP-NMRV030 to EP-NMRV150. The output flange configuration \u2014 suffix F or FA in the model code \u2014 adds a machined flange face on the output side, enabling direct bolting to rotating components such as conveyor drums, agitator paddles, rotary tables, and indexing discs without a separate hub or coupling adapter.<\/p>\n

For OEM machine designers, the value of the output flange lies in alignment precision: the flange is bored and faced on the same machining fixture as the output shaft bearing seat, so flange face perpendicularity to the output shaft axis is maintained within tight tolerances. Any component bolted to this flange is therefore centred and square to the shaft without requiring a secondary alignment procedure during assembly. This simplifies machine assembly on the production floor and reduces alignment-related failures in the field.<\/p>\n

The same EP-NMRV housing is available in standard (no flange), VS double input shaft, and AS single output shaft configurations \u2014 allowing the design engineer to specify the exact output geometry required from a common frame, simplifying BOM management across different machine variants in the same product family.<\/p>\n<\/div>\n

Application Industries for the Output Flange Configuration<\/h2>\n

The output flange version of this \u0e40\u0e01\u0e35\u0e22\u0e23\u0e4c\u0e17\u0e14\u0e23\u0e2d\u0e1a\u0e41\u0e1a\u0e1a\u0e2b\u0e19\u0e2d\u0e19<\/strong> is most commonly specified in three types of applications where a direct flange face is preferable to a keyed shaft.<\/p>\n

\u25b8 Food Processing \u2014 Rotary Filling and Dosing Heads<\/h3>\n

\"EP-NMRV<\/p>\n

Rotary filling and dosing head assemblies bolt directly to the gearbox output flange. Centring is guaranteed by the register diameter machined into the flange face, so the filling head spins concentrically without requiring run-out checks at each machine service. The EP-NMRV050 to EP-NMRV075 range covers the typical torque and speed requirements (output torque 20\u2013160 Nm, output speed 10\u201350 rpm) for filling heads in dairy, beverage, and sauce filling lines.<\/p>\n

\u25b8 Packaging Machinery \u2014 Rotary Table and Carousel Drives<\/h3>\n

\"EP-NMRV<\/p>\n

Carousel-type packaging machines \u2014 where a rotating platform carries multiple product stations past a series of fill, seal, and label heads \u2014 require a stable, precisely-centred turntable drive. The output flange provides the large-diameter pilot diameter that centres the turntable plate, while the worm gear self-locking prevents coasting when the machine stops. EP-NMRV063 or EP-NMRV075 at 20:1\u201340:1 is the most common specification in this application.<\/p>\n

\u25b8 Automation \u2014 Rotary Indexing and Cam Follower Tables<\/h3>\n

In precision rotary indexing tables for automatic assembly and inspection machines, a flat, square output flange simplifies the mechanical connection between the gearbox and the indexing plate. A servo motor driving an EP-NMRV with output flange through a close ratio (7.5:1\u201315:1) gives the combination of positioning speed and positional stiffness needed for workpiece indexing in seconds. The \u0e40\u0e01\u0e32\u0e2b\u0e25\u0e35 \u0e40\u0e2d\u0e40\u0e27\u0e2d\u0e23\u0e4c\u0e1e\u0e32\u0e27\u0e40\u0e27\u0e2d\u0e23\u0e4c<\/a> product range includes matching shaft couplings and motor flange adapters for common servo motor frame sizes.<\/p>\n

Design Advantages from an OEM Engineer’s Perspective<\/h2>\n
\n
\n

\u2726 Flange Face Perpendicularity Guaranteed<\/strong><\/p>\n

The output flange is machined on the same CNC fixture that bores the output shaft bearing seat, so flange face perpendicularity to the output shaft axis is maintained within 0.02 mm \u2014 equivalent to a precision-machined adapter plate but without the additional component and alignment step.<\/p>\n<\/div>\n

\n

\u2726 Viton Seals Standard \u2014 Temperature & Chemical Resistant<\/strong><\/p>\n

Viton (FKM) oil seals are standard on this series, not an upgrade. The Viton material resists oil degradation, is rated for continuous oil contact at up to 200\u00b0C, and withstands incidental exposure to common cleaning agents better than NBR rubber seals.<\/p>\n<\/div>\n

\n

\u2726 Multiple Housing Colour Options<\/strong><\/p>\n

Blue, black, and grey are standard; custom RAL colours are available on request for OEMs specifying a consistent machine aesthetic across their product line. The powder coat finish is applied after final assembly and dimensional inspection.<\/p>\n<\/div>\n

\n

\u2726 Full Range from One Supplier<\/strong><\/p>\n

EP-NMRV030 through EP-NMRV150 share the same dimensional scaling and documentation standards. A machine designer specifying this family across an entire product line gets a single datasheet format, single spare parts system, and single technical support contact for all frame sizes.<\/p>\n<\/div>\n

\n

\u2726 ISO 9001:2015 Production Quality<\/strong><\/p>\n

Korea Ever-Power manufactures under ISO 9001:2015. Every batch is accompanied by inspection records that include bore dimension checks, noise test results at rated input speed, and oil volume confirmation \u2014 reducing incoming inspection workload for OEM quality teams.<\/p>\n<\/div>\n

\n

\u2726 Worm Shaft 20CrMnTi \u2014 Extended Service Life<\/strong><\/p>\n

The worm shaft alloy steel 20CrMnTi undergoes carburising and quenching before precision grinding. The case-hardened surface layer resists the micro-pitting that leads to early worm gear failures in continuous-duty food processing and packaging applications running multiple shifts daily.<\/p>\n<\/div>\n<\/div>\n

A complete worm drive system includes three components beyond the gearbox housing. The worm wheel, worm shaft, and output shaft coupling each affect transmission longevity and performance. All three are available from Korea Ever-Power \u2014 combined ordering lets us verify dimensional compatibility across the full drive train before shipment.<\/p>\n

The flange output variant bolts the driven component directly to the gearbox face \u2014 no output coupling is needed in most cases. For applications using the NRV solid-shaft input or where a flexible coupling is required between output shaft and load shaft, contact us with shaft diameters and torque for a specific recommendation.<\/p>\n<\/div>\n<\/div>\n

What is the difference between the F1 and FA output flange designations?<\/strong><\/p>\n

\u2192 F1 and FA both refer to an output flange configuration but differ in the flange bolt circle diameter and register diameter. F1 uses a smaller bolt circle matched to the standard NMRV series flange template. FA is a larger alternative flange face used when the downstream component requires a wider bolt pattern or larger register. Confirm which flange type your driven component requires against the output flange mounting dimension drawing above before specifying.<\/p>\n

\n

Can the EP-NMRV150 handle 15 kW continuous duty input?<\/strong><\/p>\n

\u2192 The 15 kW figure is the upper bound of the rated power range \u2014 it corresponds to a large motor at a low ratio (e.g. 7.5:1) where both input speed and output torque are within the housing’s mechanical and thermal limits. At higher ratios and lower output speeds, the thermal power limit is the binding constraint. Confirm your specific combination against the thermal power table for the EP-NMRV150 before specifying 15 kW at ratios above 20:1 in continuous duty.<\/p>\n

\n

What IEC motor flange codes are available for the EP-NMRV063?<\/strong><\/p>\n

\u2192 The EP-NMRV063 accepts IEC flanges 71B14, 80B14, and 80B5 as standard options. The B14 face type (small flange, 4-bolt) is the most common for AC motor coupling. The B5 face type (large flange, 4-bolt through the flange body) is used for larger motor frames where the flange registers into the motor body. Specify the full motor IEC designation on your order to confirm compatibility.<\/p>\n

\n

How is the worm shaft tail extension (VS configuration) used?<\/strong><\/p>\n

\u2192 The VS configuration extends the worm shaft out of both ends of the housing. One end connects to the motor; the other end can accept a hand wheel for manual override, a position sensor or encoder, or a chain sprocket for mechanical synchronisation with another drive. It is frequently used on multi-axis systems where a common driveshaft passes through a series of gearboxes in a tandem arrangement.<\/p>\n

\n

Is the output shaft chromium steel (45#) suitable for a food contact environment?<\/strong><\/p>\n

\u2192 The standard output shaft is chromium steel 45#, which is not stainless. In a food zone, the shaft must be covered by the machine structure or fitted with a guard to prevent direct food contact. For environments where the output shaft is directly exposed to food, water, or cleaning chemicals, specify a stainless steel output shaft at time of order \u2014 this is available as a non-standard option on the EP-NMRV series.<\/p>\n

\n

What is the maximum output torque of the EP-NMRV090 at a 50:1 ratio?<\/strong><\/p>\n

\u2192 The maximum output torque for the EP-NMRV090 depends on the rated input power at your operating speed. At a 50:1 ratio with a 0.75 kW motor at 1,400 rpm input, output torque is approximately 380\u2013420 Nm accounting for worm gear efficiency at that ratio. The exact value is confirmed in the EP-NMRV090 performance table for the 50:1 ratio row. We supply per-model performance tables with each order confirmation for customer engineering records.<\/p>\n

Son Min-jun<\/strong>, Machine Design Engineer, Seoul Packaging OEM (2024)<\/p>\n

“Specified EP-NMRV063-F1 for a new carousel packaging machine. The flange register centred the turntable without any shimming \u2014 first assembly ran within spec. Model code system is logical once you learn it; ordering was straightforward. 15 machines built with this configuration so far.”<\/p>\n

Kim Ji-eun<\/strong>, Automation Engineer, Gyeonggi-do Electronics OEM (2025)<\/p>\n

“Using EP-NMRV040-FA with servo motor for a rotary indexing table. The Viton seals are holding up well after 14 months of 2-shift operation. No oil weeping and the output flange run-out is within 0.03 mm after 14 months, which is better than our previous supplier.”<\/p>\n

\n

Lim Seung-chul<\/strong>, R&D Engineer, Busan Industrial Equipment OEM (late 2024)<\/p>\n

“The model code system made BOM management much cleaner for our product line. Every variant is a unique code rather than a freetext description. DWG drawings came with the samples \u2014 integration into our CAD model took one afternoon.”<\/p>\n

\n

Choi Yeon-soo<\/strong>, Maintenance Engineer, Daegu Beverage Production Line (Q1 2025)<\/p>\n

“First oil change at 500 hours showed clean oil on both EP-NMRV075 units on our filling carousel. The Viton seals make a visible difference \u2014 the previous NBR-sealed units from another supplier started to sweat oil at around 400 hours in our high-temperature filling area.”<\/p>\n

Lee Jong-kwon<\/strong>, Plant Manager, Ulsan Automation Systems (2024)<\/p>\n

“12 units running on automated assembly tables for 16 months. Zero mechanical failures. The dimensional drawing in the documentation was accurate to the actual unit \u2014 no surprises at first installation. Good product.”<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
