SPIRAL BEVEL GEARBOXES RANGE “POWERGEAR”
3. Manufacturer’s Designated Use
POWERGEAR gearboxes are components for installation in machinery and plant and are designed
exclusively for the deflection and multiplication of torques within a speed range up to 6000 rpm. They
are compliant with machinery directives (EN 292) and EMC directives, where applicable.
Use other than or over and above that described above is contrary to the manufacturer's designated
use. The manufacturer refuses to accept liability for damage or injury resulting from such other use.
The user is the sole bearer of risk. POWERGEAR gearboxes can be used in many different
applications so responsibility for a specific application passes to the user as of when usage
commences.
4. Transportation and Storage
Damage discovered after delivery must be reported forthwith to the freight forwarder and adequate
steps to prevent initial operation must be adopted, if applicable.
Use handling gear of adequate load-bearing strength (rope slings, for example), if necessary.
Store gearboxes in dry, dust-free, low vibration environments (bearings prone to lay-up damage) at
temperatures in the range from -25 to +50°C.
5. Modifications and Alterations
Attempt no design- or safety-related modifications to POWERGEAR gearboxes without the prior,
written consent of the manufacturer.
Unauthorized alteration of any nature whatsoever voids the manufacturer's guarantee and warranty
and excludes all liability on the part of the manufacturer.
6. Installation and Assembly
When installing or assembling, make sure that
- the support on which the gearbox rests is level, adequately damped to prevent vibration, and
torsionally rigid
- the input and output drive elements (belt pulleys, couplings, universal shafts, etc.)
• are balanced
• are always installed and removed with the aid of suitable equipment
• are secured axially, even if shrink-fitted
• clamping elements, if used, must be of suitable design and tightened to
specified torque
• are fitted with guards to prevent accidental contact
• belts, if fitted, are tensioned correctly in compliance with manufacturer’s
specifications, and shearing forces do not exceed the limits permissible
for the gears
- alignment is correct in direct-drive layouts in compliance with manufacturer’s specification
- the drive assembly is free of strain in layouts with combination flange/insertion
connections
- operation is smooth and free of strain.
