ServoFoxx® Gearhead Technical Data
Steps for Reducer Selection
- Determine output torque requirements
of the gearbox. General formulas include:
- For long term continuous operation: T2 CONT = input torque
x ratio
- For long term cyclic operation: T2 CONT = input torque x ratio
x cycle factor
- Verify the input speed, cycle,
and mounting position for proper lubrication option.
- Select the appropriate backlash
value for the application.
- Determine if there are any
radial or axial loads.
- Verify motor shaft diameter
and length for bore capabilities.
- Determine if torque overload
protection is required.
Input Speed
The input speed capacity of
these gearheads is a function of size, cycle times, backlash,
bearing loads, and gear ratio.
Continuous input speeds of
3000 RPM are generally acceptable for the reducers in this category,
with the exception of some low ratio single stage models and
certain SKP2FS series ratios. Cycle speeds of up to 8000 RPM
are possible in some applications. Consult your DieQua representative
for the maximum speed possible of the gearhead selected.
Backlash
Two levels of backlash are
offered. When selecting the appropriate backlash value for a
given application, the speed and cycle times must be considered.
Continuous high speed at the lowest backlash setting may create
excessive noise and heat.
Radial Load Capacities
Radial load capacities are
based on ratio, torque, speed, and cycles. Higher speeds or more
cycles result in lower ratings. For series FS and PL2FS, consult
the product selection chart for the approximate radial load capacity.
For series PSK2FS and SKP2FS, consult your DieQua representative.
Lubrication
The operational life of any
gearbox depends greatly on proper lubrication. The correct oil
or grease applied to the gears and bearings acts as both a lubricant
and as a coolant. Speed, torque, cycle times, and gearhead mounting
position are the primary considerations in determining the correct
lubrication option.
Because of the wide variety
of models and configurations offered, different lubrication types
are incorporated. Some are oil filled, some are grease filled,
and some two and three stage designs have a combination of oil
and grease in the different stages. Generally, all models are
lubricated for the rated life of the unit and don't require lubrication
changes.
When mounting any shaft in
a vertical orientation, special considerations may be necessary.
Please contact your
DieQua representative for these proper lubrication options.
