The top of plunger is acted on, continues input hydraulic pressure oil and generates hydraulic energy promotion plunger motion, existing oil distribution casing is to pass through spring
For spring compression in seat in rotor on oily end face, spring is elastomeric element, therefore can be existed by spring compression oil distribution casing
Oil distribution casing and rotor is set to be bonded and can match to rotor by spring because of the phenomenon separated with oily end face of oil distribution casing and rotor, and only
The machining accuracy of oily end face and oil distribution casing is higher, causes that the production cost increases.
Summary of the invention
Oil distribution casing and matching reliably with oily end face can be improved the technical problem to be solved by the utility model is to provide a kind of
Property, reduce the hydraulic motor oil distribution mechanism of food tray machining accuracy.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of hydraulic motor oil distribution mechanism, packet
Shell and logical food tray are included, the shell and the logical food tray sealing are fixed, and rotor are provided in the shell, described turns
The front end of son and the housing seal cooperate, and the rotor passes through the shell and protrudes into the interior of the logical food tray
Portion, the integral middle of the rotor are provided with plunger case, radially uniform distribution of the plunger case along the rotor, institute
It is provided with plunger in the plunger case stated, the rear end face of the plunger case is provided with a point oilhole, the described oilhole and described of dividing
Cavity in plunger case is connected, and is provided with oil distribution casing between the rotor and the logical food tray, on the oil distribution casing
It is provided with distributor port, the distributor port is provided in the radially uniform distribution of oil distribution casing, the logical food tray matches with described
The corresponding fixation hole of oilhole, and the fixation hole embeds and is cased with hollow fixing seat, the fixing seat is matched with described
Oilhole is connected, and oil-through-hole is provided on the logical food tray, the oil-through-hole is connected with the fixation hole, described
Oil distribution casing back-end sealing is fixed with capping, and the shell, logical food tray, rotor and oil distribution casing are coaxially disposed.
Preferably, the front end of the rotor is mutually fixed by bearing with the shell, and the rear end of the rotor is logical
Bearing is crossed mutually to fix with the logical food tray.
Preferably, the both ends of the fixing seat are provided with groove, and sealing ring is provided in groove.
Preferably, being provided between the rotor and the capping prevents the movable washer of the rotor axial.
Compared with prior art, the utility model has the advantages that being provided with fixation hole on logical food tray, fixation hole is embedded to be cased with
Fixing seat, fixing seat offset with oil distribution casing, fit closely oil distribution casing with rotor, reduce oil distribution casing machining accuracy reduce at
This, the washer being arranged between capping and rotor can reduce the axial activity of rotor, further ensure between rotor and oil distribution casing
Fit closely degree, and then make between the plunger case of hydraulic motor with oil more balancing.
