Hydraulic gear motor, how it works

Visit hidraulicapractica com. You can see the interior of the motor, gears, body. Watch how the oil is pushed into the inlet port and through the oulet traveling between the gear teeth and the gear housing, generating the rotation of the shaft.

what is the purpose of the case drain and where it is going,, into the tank?

[camilohrueda]

@betneth In a hidraulic motor, there can be times when both ports are going to have high pressure at the same time. When this happens, the shaft seal can blow up unless the chamber behind it is connected to the tank. This allows all the internal leaks to go freely to the tank.

@camilohrueda ;; thanks for the info man,, im a hydraulic mechanic also,, specialy on earth moving machine,,,thats why i know little about hydraulic.... hehehehehe.... thanks a lot again,,,,

[camilohrueda]

@betneth NOP!

[azremyyyyyy]

which one more better,hydraulic motor or electrical motor

[camilohrueda]

@azremyyyyyy It depends on the application, and many more factors.

16 year Aircraft Hydraulic guy here... The difference between a hydraulic pump, and a hydraulic motor, is which way the energy input/output is going. It is the same component. If the fluid is turning the shaft, then it is a hydraulic motor. If the shaft is pushing the fluid, then it is a hydraulic pump.

@FordsRule351

not really, hydraulic systems don't make power, they transmit power. What makes hydraulics so helpful is that you have total control over the torque & rpm in the motor 's shaft (output) among other reasons.

@lightrose100

36cc motor, 1000RPM, 96%vol eff, 92%mech eff

22cc Pump, 1757RPM, 97% vol eff, 92% mech eff

20HP Electric Motor (1750RPM)

System pressure = 3000PSI, System Flow = 9.91GPM

Start with the motor, calculate requ. hp, flow, torque, apply to the pump, find torque and speed data and solve for engine requ. HP = GPM *PSI / 1714* eff.

creo que esto no es un motor hidraulico, es una bomba hidraulica, uno de los engranajes es accionado por un vastago unido a normalmente el arbol de levas de un motor de explosion o diesel, haciendo girar al otro eng,. y de esa manera suministra presion hidraulica al sistema de lubricacion de dicho motor. no se debe confundir, no creo que oueda trabajar como motor hidraulico.

@azremyyyyyy well i have used a lots of winches (PTO, electrics and Hydraulics, manuals) and in my opinion if you compare electric vs hydraulic, the hydraulic will beat a electric forever

[lightrose100]

@camilohrueda ..Hi .I got a question if you could help me out i'd appreciate it very much, I;m trying to get 80 foot pound of torque @ 1000 r.p.m on a hydraulic motor, what size or kind of pump do I need and what h.p electric motor do I need? thanks!

Construction design same

@betneth

Case drain is due to the relieved tolerances on the pump components so that some oil seeps through and acts as a lubricating media. After its lubrication purpose is achieved, the left over oil in the base of the pump has to be recycled and is sent back to the accumulator tank through filtering.

@iryshrovrs what the hek man ur a genius..
