Gear unit The following table shows the temperature range for the standard oil supplied with each gear unit. Alternate oils are available per the lubricant table ( 111). Gear unit Standard Lubricant Temperature range R F K..7 CLP VG0-15 C to +40 C K..9 CLP PG VG460-0 C to +60 C S CLP VG680 0 C to +40 C W CLP PG (SEW) VG460-0 C to +40 C The rated data of the gearmotors specified in this catalog refer to an ambient temperature of +5 C (77 F). With proper project planning, gearmotors from SEW-EURODRIVE can operate from -40 C to +60 C (-40 F to +140 F). Project planning must consider special operating conditions and use appropriate lubricants and seals. It is especially important for the following gear units: R, K, F gear units > size 87 with small ratios due to oil churning heat All S gear units (helical-worm), due to sliding friction especially with large ratios or low input speeds. SEW-EURODRIVE will perform this project planning for you.

Product description Product features Motors The motors of the DRS..and DRN.. series are designed for use in a temperature range from -0 C to +40 C (-4 F to 104 F). This expands the standard temperature range required by IEC Using the motors outside the above temperature range is possible with some special adjustments. Please contact SEW-EURODRIVE for available options. INFORMATION If the motor is controlled by a frequency inverter, you must also consider the project planning notes for the inverter and take into account the thermal effects of inverter operation..1. Altitude Error! Due to the low air density at high installation altitudes, heat dissipation decreases on the surface of motors and gear units. The rated data listed in the catalog applies to a maximum installation altitude of 380 feet above sea level. Proper project planning must be considered for higher altitudes to ensure proper cooling ( 57)..1.3 Power and torque The power and torque ratings refer to mounting position M1 and similar mounting positions in which the input stage is not completely submerged in oil. In addition, the gearmotors are assumed to be standard versions with standard lubrication and under normal ambient conditions..1.4 Speeds The output speeds shown are based upon the rated motor speed and the gear unit ratio. Please note that the actual output speed depends on the motor load and the line voltage conditions..1.5 Noise Error! The noise levels of all SEW-EURODRIVE gear units, motors and gearmotors are well within the maximum permitted noise levels set forth in the VDI guideline 159 for gear units and IEC/EN for motors..1.6 Reduced backlash Helical (R-series), the Snuggler helical (F-series) and helical-bevel (K..7 series) gear units with reduced backlash are available in gear size 37 and larger. K..9 helical-bevel gear units are not available with reduced backlash /EN-US 04/018 The rotational clearance (backlash) of these gear units is considerably less than that of the standard designs; therefore, positioning tasks can be solved with great precision. The rotational clearance is specified in angular minutes and is shown in the "Possible combinations" section within each gear unit chapter ( 160). The rotational clearance for the output shaft is specified without load (max. 1% of the rated output torque) with the gear unit input end blocked. Catalog DRS/DRN.. Gearmotors 13

The distance is necessary for air circulation/heat dissipation, and for maintenance of the brake or MOVIMOT inverter, if installed Weights Please note that all weight specifications in the catalogs apply to gear units and gearmotors without lubricant. The weights vary according to gear unit design and size. The lubricant volume depends on the mounting position. Suggested values for lubricant fill quantities based on the mounting position are provided in the chapter "Oil fill quantities" ( 113). The exact weight is shown on the order confirmation Compound gearmotors Particularly low output speeds are possible by using compound (multi-stage) gear units (ex: K87R57). These units contain an additional helical gear unit on the input in order to achieve much higher ratios than those in a single gear unit. However, it may be necessary to limit the motor power or to provide torque overload protection in order to ensure that the maximum permissible output torque of the gear unit is not exceeded..1.1 Shaft diameters All gear units are available with either an inch or a metric diameter output shaft. In addition, several diameters are available for each output shaft at no extra charge. See Output shaft sizes at the end of each dimension section /EN-US 04/ Catalog DRS/DRN.. Gearmotors

4 Product description Product features.1.13 RM gearmotors RM gearmotors are a special type of helical gear unit with an extended output bearing hub. They are designed especially for agitating applications to allow for high overhung loads, axial loads, and bending moments. You can find special project planning notes for RM gearmotors ( 60) SPIROPLAN gearmotors SPIROPLAN (W-series) are robust right-angle gear units with either single or two stage gearing. Unlike the helical-worm gear units (S-series) that use both bronze and metal gears with sliding friction, the SPIROPLAN units use only steel gears with a special meshing pattern that incorporates both sliding and rolling friction for greater efficiency. In addition, the housing is aluminum. Therefore, SPIROPLAN gearmotors are wear-free, lightweight, and compact. The wear-free gearing and the life-long lubrication provide a long period of maintenance-free operation. For maximum mounting versatility, the spacing of the holes on the feet is the same on all three sides. In addition, the shaft height remains the same regardless of the side upon which the unit is mounted. Also, two different flange diameters are available for each unit. As an option, SPIROPLAN gearmotors can be equipped with a torque arm Brakemotors Error! B ookmark not d efined.error! Boo kmark not defin ed. Motors and gearmotors can be supplied with an optional integrated mechanical brake. The SEW-EURODRIVE brake is an electromagnetic disk brake with a DC coil that releases electrically. Braking occurs via a combination of adjustable spring forces. Due to its operating principle, the brake is automatically applied during a power failure, meeting basic safety requirements. The brake can be released mechanically if equipped with manual brake release that is available as either an adjustable setscrew or as a hand lever with automatic reset. The brake is controlled via a rectifier that is installed in either the motor conduit box or inside the control cabinet. The brake bearing endshield is a part of both the motor and the brake, yielding an integral design and a very compact brakemotor Motor adapters Error! Bookmark not defined.error!

Product description Oil aging monitor: DUO10A INFORMATION To prevent the VCI anti-corrosion agent from evaporating, the gear units with "extended storage" must remain tightly sealed until startup. The gear units come with the oil fill according to the specified mounting position (M1 M6). Always check the oil level before placing the gear unit into operation..4 Oil aging monitor: DUO10A The oil condition monitoring option consists of a temperature sensor and the evaluation unit. Service life curves for oils supplied by SEW-EURODRIVE are stored in the evaluation unit. In addition, SEW-EURODRIVE can customize any other oil grade in the diagnostic unit. During operation, the evaluation unit uses the oil temperature to continuously calculate the remaining service life in days until the next oil change. The remaining life is displayed directly on the evaluation unit. When the service life is expired, a binary signal can be sent to a higher-level system and evaluated. Using the DUO10A diagnostic unit, the system operator no longer has to replace the oil within predefined intervals, but can adapt the replacement interval individually to the actual load. The benefits are reduced maintenance costs and increased uptime. For more information, ( 157)..5 Oil expansion tank The oil expansion tank allows the lubricant or air space of the gear unit to expand. This means no lubricant can escape the breather valve at high operating temperatures. SEW-EURODRIVE recommends using an oil expansion tank for gear units and gearmotors in M4 mounting position and for input speeds > 000 rpm. The following figure shows the oil expansion tank of a gearmotor /EN-US 04/ The oil expansion tank is delivered as assembly kit for mounting onto the gearmotor. In case of limited space or of gear units without motor, the oil expansion tank can also be mounted to nearby machine parts. Catalog DRS/DRN.. Gearmotors 1
