MRV050 Worm Gear Reducer \u2014 Extended-Power Packaging Series, 0.06\u20137.5 kW<\/h2>\n
\n
\n

\u306e MRV050 worm gear reducer<\/strong> is an upgraded variant of the standard RV050 design, engineered to extend the motor power range in both directions \u2014 down to 0.06 kW for micro-motor and light-duty packaging drives, and up to 7.5 kW for heavier continuous-duty lines. The standard RV050 typically tops out at 1.5 kW; the MRV050 covers a 125\u00d7 range from the lightest label applicator motor to a substantial filling line drive, all within the same compact 50 mm centre-distance housing footprint.<\/p>\n

The ratio range runs 5:1 through 100:1, including the non-standard 12:1 (117 rpm output) and 52:1 (27 rpm output) steps that are absent from the standard RV series catalogue. These intermediate ratios are particularly useful in packaging equipment where belt or roller surface speed is specified as a fixed line requirement and standard ratios produce outputs that are either 15\u201320% too fast or too slow \u2014 forcing the use of an inverter to compensate.<\/p>\n

Both 71B14 and 80B14 IEC flanges are standard. The housing is the same ADC12 die-cast aluminium alloy used in the RV series, maintaining dimensional compatibility with existing RV050 mounting arrangements when upgrading motor power on a machine rebuild.<\/p>\n<\/div>\n

What Makes the MRV050 Different from the Standard RV050<\/h2>\n

\"MRV050<\/p>\n

The standard RV050 was designed around a 1,400 rpm four-pole motor input with a power ceiling of approximately 1.5 kW. That boundary works well for conveyor and simple machinery drives but becomes a constraint in two directions that packaging equipment frequently hits: the need for very small fractional-kilowatt motors in label applicators and portion dispensers, and the need for higher continuous power in filling and sealing stations running multi-layer film at high speed.<\/p>\n

The MRV050 addresses both. The motor power floor drops to 0.06 kW \u2014 small enough for a label peel-and-apply mechanism or a portion dispenser dial actuator. The ceiling rises to 7.5 kW, which covers single-stage sealing heads, film tension drives on wider web machines, and heavier material handling at line entry. The housing dimensions and IEC flange patterns remain compatible with the standard RV050, so upgrading an existing machine from one to the other during a rebuild does not require bracket modifications.<\/p>\n

The worm gear design itself remains the same type \u2014 phosphor bronze wheel, 20CrMnTi case-hardened worm shaft, ADC12 die-cast aluminium housing \u2014 with the additional power handling addressed through updated bearing selection and thermal management at the higher power ratings. The oil-bath lubrication at the upper power range carries more heat away from the mesh than grease lubrication would, which is why the MRV050 specifies oil-bath as standard across the full power range.<\/p>\n

<\/p>\n

Why Packaging Engineers Specify the MRV050<\/h2>\n
\n
\n

\u2726 Power Range 0.06\u20137.5 kW in One Frame<\/strong><\/p>\n

A packaging line often has both 0.06 kW dispenser drives and 2.2 kW filling station drives on the same machine. Specifying the same 50 mm centre-distance unit across both stations simplifies maintenance, reduces spare parts inventory, and means every technician on the line is familiar with the same gearbox type.<\/p>\n<\/div>\n

\n

\u2726 Non-Standard 12:1 and 52:1 Ratios<\/strong><\/p>\n

These two ratios hit output speeds (117 rpm and 27 rpm) that fall squarely between standard ratio steps. In a packaging line where belt surface speed is derived from a fixed mechanical ratio rather than an inverter, having the right ratio in catalogue avoids under\/over-speed and the associated product presentation problems.<\/p>\n<\/div>\n

\n

\u2726 Direct Dimensional Compatibility with RV050<\/strong><\/p>\n

Same housing footprint, same IEC flange bolt patterns, same output shaft diameters as the standard RV050. Upgrading to MRV050 on an existing machine requires only a motor and gearbox swap \u2014 no mechanical redesign of the surrounding structure or guard panels.<\/p>\n<\/div>\n

\n

\u2726 Full Fr2 Load Data at Each Ratio<\/strong><\/p>\n

The permissible radial force Fr2 is published for every ratio in the table above. For packaging drives where a sprocket or timing pulley is mounted directly on the output shaft, Fr2 determines the maximum chain or belt tension the output shaft bearing can sustain without fatigue damage \u2014 a figure many competitors omit from their datasheets.<\/p>\n<\/div>\n

\n

\u2726 20:1\u4ee5\u4e0a\u306e\u6bd4\u7387\u3067\u30bb\u30eb\u30d5\u30ed\u30c3\u30af<\/strong><\/p>\n

Static self-locking at these ratios eliminates the need for a motor brake on vertical label reel lifters, vertical film feed bobbins, and similar mechanisms where the drive must hold position when power is removed. This simplifies both machine design and electrical control.<\/p>\n<\/div>\n

\n

\u2726 VFD and Servo Compatible<\/strong><\/p>\n

The IEC motor flange accommodates servo motor face plates as well as standard AC motors. Combined with a fixed mechanical ratio, servo driving via MRV050 delivers the smooth, repeatable positioning needed in dosing and portioning stations where product weight accuracy directly affects compliance.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

\u7523\u696d\u7528\u9014<\/h2>\n

\u25b8 Packaging Equipment \u2014 Filling, Sealing and Labelling Lines<\/h3>\n

\"MRV050<\/p>\n

Vertical form-fill-seal machines use multiple drives simultaneously: a film pull-down motor (0.37\u20130.75 kW), a film tension brake (0.06\u20130.12 kW), a sealing head drive (0.55\u20131.5 kW), and an indexing conveyor (0.12\u20130.37 kW). The MRV050 covers all four stations from a single catalogue entry. Label applicator peel-and-apply systems typically run at 15:1 or 20:1 (93 rpm or 70 rpm output) with a 0.09\u20130.12 kW motor \u2014 ratios and power levels where the expanded MRV050 range gives more motor selection flexibility than the standard RV050 would.<\/p>\n

\u25b8 Food Processing Machinery \u2014 Portioning and Transfer<\/h3>\n

\"MRV050<\/p>\n

Portion weighers and multi-head weighing scales use small individual drives (0.06\u20130.18 kW) on each weigh bucket agitator. The MRV050 at 20:1 or 25:1 ratio covers the typical 56\u201370 rpm bucket drive speed with motors down to 0.06 kW \u2014 a power level the standard RV series does not support. Transfer conveyors immediately downstream of the weigher typically require 0.37\u20130.75 kW at 30:1\u201340:1 (35\u201347 rpm), also well within the MRV050 range, allowing a single gearbox family to cover both functions.<\/p>\n

\u25b8 Dyeing, Textile and Chemical Processing<\/h3>\n

\"MRV050<\/p>\n

Dyeing machines use multiple slow-speed paddle and agitator drives at 10\u201330 rpm output, typically 0.25\u20130.75 kW. The MRV050 at 40:1\u2013100:1 covers this range directly. Chemical processing lines require similar torque and speed profiles for slow mixing, dosing pump drives, and valve actuators. The compact housing size is an advantage in process equipment where space inside the machine enclosure is tightly constrained and a larger WP-series cast iron unit would not fit.<\/p>\n

<\/p>\n

Motor Selection and VFD Pairing for Packaging Lines<\/h2>\n

Two approaches are common for packaging line drives using the MRV050:<\/p>\n
