Abstract
The utility model relates to a hydraulic motor and is used to eliminate inefficiency of prior products. The hydraulic motor of the utility model comprises a rotator consisting of a main casing and an end cover, an output shaft connected with the rotator, a main shaft, a wheel, an output shaft, a protection cover and an isolation and spacing part and so on. When high pressure liquid is imported from an outlet, high pressure liquid flows to a groove on the wheel through an inlet and a hydrojet port, and flows into a gap between wheel ring face on the first side of the isolation and the spacing part and inner wall of a chamber. High pressure liquid drives the rotator, the wheel and the output shaft to turn in phase by impacting inner wall of the chamber. The main shaft remains stationary; liquid with pressure released enters a returning chamber through a guide groove on a wheel on the second side of the isolation and spacing groove, and then flows out through a returning port and the outlet. The hydraulic motor is characterized in high energy conversion efficiency and high rotation rate driven by low pressure liquid.
Description
Technical field
The utility model relates to oil hydraulic motor, more particularly, relates to a kind of efficient height, can export the oil hydraulic motor of higher rotation speed under the liquid driven of lower pressure.
Background technique
In order to realize energy transfer, need drive the object rotation with highly pressurised liquid usually, also just produced oil hydraulic motor.The middle oil hydraulic motor of prior art mainly contains sliding-vane motor and piston motor.Though they have the structure of rotation, the motion mode of its displacement-variable device remains the straight line translation, perhaps should claim to be superimposed on the straight line translation of rotation.Both transfiguration principles are different.Sliding-vane motor is that utilization blade of radial expansion in executing rotor is cut apart the volume generating period variation that eccentric relatively cavity volume causes sector region between blade.Piston motor then is to utilize the radially translation of plunger in rotor rotated to cause radially translation in the little cavity volume to cause the volume-variation of little cavity volume, and the latter also needs accurate cylinder or end face flow structure come cooperating.
Though this two classes machinery is simple in structure, the inertia dynamical reaction is also less, and it is self-regulation that its blade and plunger all have power, needs dependence to add restraining force and comes balance.The common feature of mechanism's friction of two class machineries is: the restraining force that generates frictional force all is maximized.Therefore, the Billy of the interior mechanical loss of these two kinds of machineries is too high, and they also all depend on lubricated consumingly.
There is efficiency bottle neck too in second kind of transfiguration mode---the rotary volume-variable mode of prior art.The rotary volume-variable mode can be subdivided into three classes: spiral motion mode, gear engagement motion mode and eccentric wheel rotation mode.Say that on the whole it is self-regulation that the motion of rotary volume-variable mode has power, this helps reducing mechanism's friction loss greatly.But the another kind of interior mechanical loss of rotary volume-variable motion has become outstanding problem again, and under the individual cases, its volume loss also may be excessive.
Except above-mentioned efficiency bottle neck, another problem of existing fluid machinery is the monotony of target and product.Monotony is exactly not general, and a kind of product can only be used for a purpose, and can only be under using under a kind of condition of setting.
