The gantry has a speed of 4 m/s and achieves acceleration rates of 50 m/sA over the entire working area thanks to a clever design that connects both toothed belt
axes to the cross member with a single rotating toothed belt
around the drive shaft.
Taking into account that in the loading mechanism there is the external force acting on the vertical rack 12 of each of four test stations, the reduced moment of resistance forces can be expressed by the following relation: [M.sub.r] = ([F.sub.r] + [F.sub.f])[v.sub.car]/[[eta].sub.red][[eta].sub.belt][[eta].sub.bear][omega], where [F.sub.r] is the total effective resistance force on electromechanical axis' slide 15 from four stations; Ff is the maximum no-load resistance to shifting of axis 7 (***, 2010); [[eta].sub.red][[eta].sub.belt][[eta].sub.bear], are the efficiencys of the gear unit (***, 2009), of the toothed belt
drive, and of the rolling-contact bearing couple.
Unlike conventional toothed belt
axes, which feature a full-length profile, the ELGR axis is only supported at either end, and relies on the rigidity of the steel bearing guides to ensure straight carriage movement.
It was also said to have been among the first industrial engines to use a toothed belt
as camshaft drive.
* Gear trains or toothed belt
assemblies incorporated into designs to accommodate rotary shaft encoders
A toothed belt
is used for good torque transmission, mid pulley ratios are available to run up to 15,500 rpm at 60Hz.
The shaft movements are synchronized by a toothed belt
outside the center plate.
In the case of a toothed belt
, stick-slip can cause the teeth to snap off, increasing belt slippage, generating friction and heat, leading to catastrophic belt failure.
The system consists of toothed belts
arranged in a roller to roller fashion, and toothed belt
from drive to motor.
By integrating the load cell into the toothed belt
system of the BL A420 CW, it is able to check each carton's weight and verify carton position at all times.
The C evolution is equipped with a drivetrain swing arm with liquid-cooled permanent magnet synchronous motor via a toothed belt
and ring gearing.
The leading international supplier of automation equipment, Festo, has launched a new cost-effective electric toothed belt
axis with high feed forces and flexible motor attachments.
