Transit Mixer Eaton 3933 4633 5433 6433 7630 motor
CZPT Eaton concrete mixer truck motor 3933 4633 5433 6433 7630
Nominal Force: 420 bar (6000 psi) and Peak Stress 480 bar (7000 psi)
Displacement from 63.7 to 124,8 cm3/r (three,89 to 7,62 in3/r)
Eaton has the guide situation in supplying reputable and tough technique answers for transit mixers-automobiles on which downtime can mean disaster. No matter whether the truck is touring down a freeway or idling at a traffic gentle, the drum should maintain a constant rotation velocity. Which is no difficulty when Eaton is on the inside of. Eaton pump and motor provide the higher pressure and substantial circulation essential to hold drums rotating.
Superior cylinder barrel layout – permits large speed and strain.
Fastened clearance slipper hold down – on Types 39 through sixty four makes it possible for procedure at substantial pace and lowers friction. Product seventy six is a ball information device.
Pistons – have prolonged engagement with cylinder bore resulting in reduced leakage.
CZPT servo control – gives reduced energy operation with reduced manage pressure. Large servo pistons keep swash plate situation and supply damping.
Large case drain ports – reduce scenario back strain.

˜ These shaft speeds need optimum charge stress aid: 340 psi (23 bar) pump and 280 psi (19 bar) motor.
* Nominal Pressure: Max delta method stress at which ingredient fatigue does not arise (pump daily life approximated by bearing daily life).
** Peak Force: Max operation pressure which is permissible for a short period of time (t < 1 sec).
*** Greatest output torque is measured at 6000 psi (415 bar).
The motor employs the substantial stress oil circulation from the pump to generate transmission output. The higher stress oil will come to the motor through 1 of the high strain strains. It enters the motor, turns the output shaft, then returns to the pump. Eaton piston motors integrate a very hot oil shuttle and minimal pressure aid valve into the finish include. The shuttle valve and minimal pressure relief valve immediate surplus demand pump flow into the motor case. The shuttle valve is activated by substantial stress and directs excess demand pump circulation in excess of the minimal force relief valve. This flushing action allows the demand pump to supply cleanse, cool oil to the closed loop circuit.
