Product Description
Series K right angle drives helical bevel geared motors offer ratios from 8:1 to 160:1 in three stages or up to 10000:1 in five stages.
Motors are available up to 90kw and output torque capacity up to 12,300 Nm.
The Series K geared motor is designed with integral cast feet base or end mounting and can be offered with single or double-extended output shafts.
Units are also available shaft-mounted or with output flanges and are available for mounting horizontally or vertically.
The units can also be offered with a bolt-on torque reaction bracket and all variants are available either motorized or with an input shaft assembly.
Design Features Include:
Patented standard motor connection (IEC) Ability to ft double oil seals, on output shaft or reducer input shaft as required. All units are dimensionally interchangeable with other major European manufacturers Braked geared motors are available as standard Units are manufactured and assembled from a family of modular kits for distributor friendliness minimizing inventory and maximizing availability Motorised units can be fitted with a backstop module and reducer units can be fitted with a backstop and fan.
As improvements in design are being made continually this specification is not to be regarded as binding in detail and drawings and capacities are subject to alteration without notice. Certified drawings will be sent on request. Gear unit selection is made by comparing actual loads with catalog ratings. Catalog ratings are based on a standard set of loading conditions, whereas actual load conditions vary according to the type of application. Service Factors are therefore used to calculate an equivalent load to compare with catalog ratings. i.e.
Equivalent Load = Actual Load x Service Factor
Mechanical Ratings and Service Factors Fm and Fs:
Mechanical ratings measure capacity in terms of life and/or strength, assuming 10 hr/day of continuous running under uniform load conditions.
Catalog ratings allow 100% overload at starting, breaking, or momentarily during operation for up to 10 hours per day. The unit selected must therefore have a catalog rating at least equal to half maximum overload. Mechanical Service Factor Fm (Table 1) is used to modify the actual load according to daily operating time, and type of loading.
Load characteristics for a wide range of applications are detailed in Table 3 opposite, which are used in deciding the appropriate Service Factor Fm from Table 1. If overloads can be calculated, or accurately assessed, actual loads should be used instead of Fm.
For units subjected to frequent stop/starts overloads in excess of 10 times/day multiply factor Fm x Factor Fs (table 2). For applications where units are to operate in extremely dusty or moist/humid atmospheres unit selection should be referred to application engineering.
