3.1 General description
The FLENDER
®
gear unit (referred to below simply as "gear unit") described in these operating
instructions has been developed to drive a wide range of machines in general machinery
construction.
The gear unit is available as one, two, three, four, five or six-stage helical or bevel helical gear
unit. These are designed for horizontal mounting. The gear unit is also available for other
mounting positions on request.
When required, standard gear units can be equipped with a motor bell housing, motor swing
base, torque arm, oil cooler and backstop.
It can essentially be operated in both directions of rotation. Gear units equipped with backstop
or overrunning clutch are the exceptions in this case. Flender must be consulted if, for these
versions, the direction of rotation is to be reversed.
Designs
Various shaft arrangements (designs and directions of rotation) are possible. Additional
information and a detailed illustrated description can be found in the dimension drawing in the
complete gear unit documentation.
NOTICE
Destruction of the gear unit or parts of the gear unit due to incorrect direction of rotation is
possible.
Depending on the specific contract, the gear unit can have one direction of rotation if it is
equipped with a backstop or overrunning clutch.
