The internal highlights
4
The wide range of applica-tions and application fields of the automation industryhave been considered whendesigning the ValueGear. The ValueGear consequentlycombines high quality withlow costs due to optimizedproduction.
❑ Single stage right anglegearbox in ratios 1:1 and 2:1
❑ The compact aluminiumdesign provides a smallbox size with low weight
Aluminium extruded profilewith T-grooves for universaladaptation
Optimized gear tooth contactpattern during assembly leading to uniform load distribution
❑ The gearbox is lubricated for life and under normalindustrial conditions thegearbox is maintenancefree after installation
❑ The efficiency of the gearbox, 98%, saves energy costs
Parameter optimized Gleasongearing guarantees a long lifetime and quiet operation
High quality bearings taking axial and radial load to guaranteelong operational life
Maximumusage of thebox internalvolume for gearing
Fretting free torque transferusing a shrink fit between theshaft and gearwheel

The external highlights
Solid shaft configurationShaft arrangement 1L
Shaft arrangement 13L
Hollow shaft configurationShaft arrangement 13LH
The real advantages of theValueGear design will befound in applications with the following requirements:
❑ Medium torque at medium input speeds
❑ Low weight and small box size
❑ Robust, reliable and maintenance free
❑ Universal adaptation by T-grooves and basic elements for assembly
Typical applications for the ValueGear are angulartorque transfer and torque distribution in solid shaft andhollow shaft configurations, for packing machines andtransfer lines.In non-stationary applicationswhere weight is extremely im-portant, the compact design is the ideal solution.
Our product specialists would be happy todiscuss with you your specific requirements.

Thermal per-formance limitThe gearbox performance is limited by the maximumallowable operating tempera-ture. The required effectiveperformance must not exceedthis limit for permanent usage.
For intermittent application and for raised environmental temperatures the following factors can be applied as a guide line for the thermal performance limit.
Duty cycle per hour = 100% 80% 60% 40% 20%Factor 1 1.2 1.4 1.6 1.8
