Assembled with all-steel construction, thicker sidewalls, and a rotor shaft
with solid steel discs, the RTI grinders are equipped with CNC-machined, scalloped rotor knives that are six times index-able.
The last airworthiness directive is applicable to certain Airbus A300-600 series aircraft and requires modification of certain electrical looms of the nose and main landing gear and modification of the rotor shaft
attachment of the nose and main landing gear tachometers.
The capacitance between the motor stator and the rotor induces a stray voltage on the VFD rotor shaft
Rotor Connection: Star, Insulation Class F/F, Enclosure: Tefc Sr, Frame: Ks 180L2, Rating: S4, 60 Percent, Amb: 47 Degree C, Double Extended Rotor Shaft
, De Bearing: 6310Zz, Nd Bearing: 6310Zz, Ref: Is: 325/1996, Ref: Bs En 60034/1995.
The plug-in mechanism is said to enable quick cleaning of the rotor shaft
As a result, brush seals were developed to accommodate the radial movements of the dynamic rotor shaft
due to the flexibility of their bristles.
Distinctive features of the RTI vertical rotary grinders include the rotor shaft
that incorporates strategically keyed 1[3/4]-inch x 11-inch solid steel discs, each pocketed to accept three knife holders.
The rotor shaft
is an AISI 4340 forging quenched and tempered to a specified brinell hardness.
This axial force overcomes the return force of the brake spring, moving the rotor shaft
and brake disc in an axial direction.
In addition, it is constructed of heavy-duty aluminum and stainless steel for durability and is available with a choice of an 18-, 24- or 31-in, graphite rotor shaft
with a 6 x 6-in, graphite rotor.
In a turbine meter, life expectancy is related to the load and speed of the main rotor shaft
bearings, where a rotor may turn at speeds up to 10,000 rpm.
