Torque unit (pic. 8) consists of two function units:
·
torque disk (pic. 8)
·
torque unit (pic. 9) with locking mechanism (82)
Torque disk (pic. 8) is connected to torque
shaft (45) discharged from force trans-mission
(pic.2). The torque disk turn angle is proportional to
torque of output shaft (3) of elec-tric actuator. Its
magnitude is adjustable by set up of segments (17)
and by shifting of back-stops (18). Achieved torque
value is from torque disk transferred to torque unit
(pic.9) via tor-que lever (42).
Remark:
The marks on the scales determine the range of turn-off torque (min. and max. value for given
make), within which can the torque magnitude be adjusted, the value of turn-off torque is not implicitly
stated, during set up serve only for more accurate orientation about its magnitude without testing
device for torque measurement.
Torque unit (pic.9) is created by a console with switches
S1 (20) and S2 (21). On the shaft (23) are located turn-off
levers (24), which by the spring force keep switches
contacted until the moment when the shaft from torque
turn-off drive will be turned.
Locking mechanism (82) (pic.3, 9) provides locking of
torque turn-off usually at 1 or 2 revolu-tions after reversing
of electric actuator. Torque unit will gain its original
function after elap-sing of set up revolutions.
Pic. 9
Heating resistor
The electric actuator is provided by heating resistor (16) (pic. 3 respectively 4) with total output
20 W. The connection of heating resistor is dependent on working environment (see art. 1.5.1).
Electric connection
Electric connection can be performed via terminal board (58) (pic.3, 4) or connector.
