Abstract

The utility model discloses a kind of hydraulic pump lateral plate structure, including plate body, plate body is symmetrical above and below to be provided with two axis holes, plate body or so end face middle part is respectively equipped with left oil-out, right oil-out, plate body upper and lower end face is plane, and the outer wall between plate body upper and lower end face and left oil-out, right oil-out is arcwall face;Left compensating groove, right compensating groove are interval with plate body between left oil-out, right oil-out.The utility model novel in structural design, can reduce frictionally damage, improve the mechanical strength of side plate, it is ensured that pump continually and steadily works.

Description

A kind of hydraulic pump lateral plate structure
Technical field:
The utility model is related to hydraulic pump to manufacture field, more particularly to a kind of hydraulic pump lateral plate structure.
Background technology:
Hydraulic pump provides a kind of Hydraulic Elements of fluid under pressure for hydraulic drive, is one kind of pump.Its function is dynamic The mechanical energy of power machine (such as motor and internal combustion engine) is converted into the pressure energy of liquid.Influence the service life factor of hydraulic pump very It is many, except pump itself design, manufacture factor are outer and some used with pump related elements (such as shaft coupling, oil filter) selection, Operation during trial run and run etc. also has relation.
The side plate of hydraulic pump is used in the inner side of end cap, is set on main shaft, and side plate upper and lower end face is in hydraulic pump works process In easily there is frictional dissipation, additionally, impulsive force is larger in unloading process, easily there is metaboly, continuous firing in side plate After a period of time, the service behaviour of hydraulic pump is influenceed.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of hydraulic pump lateral plate structure, structure Modern design, can reduce frictionally damage, improve the mechanical strength of side plate, it is ensured that pump continually and steadily works.
The technical solution of the utility model is as follows:
Hydraulic pump lateral plate structure, it is characterised in that including plate body, plate body is symmetrical above and below to be provided with two axis holes, and plate body is left Right side middle part is respectively equipped with left oil-out, right oil-out, and plate body upper and lower end face is plane, and plate body upper and lower end face is fuel-displaced with a left side Outer wall between mouth, right oil-out is arcwall face;
Left compensating groove, right compensating groove are interval with plate body between described left oil-out, right oil-out.
Described hydraulic pump lateral plate structure, it is characterised in that described left oil-out, right oil-out are symmetrical arranged, it is left Oil-out, right oil-out are semicircular breach.
Described hydraulic pump lateral plate structure, it is characterised in that described left compensating groove is the waist through hole through plate body.
Described hydraulic pump lateral plate structure, it is characterised in that described right compensating groove is the blind slot of kidney-shaped, blind slot middle part The unloading hole of biasing is provided with, unloading hole runs through plate body.
The utility model has the advantages that:
The utility model novel in structural design, can reduce frictionally damage, improve the mechanical strength of side plate, it is ensured that pump is lasting Steady operation.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Specific embodiment:
Referring to accompanying drawing:
Hydraulic pump lateral plate structure, including plate body 1, plate body 1 is symmetrical above and below to be provided with two axis holes 2, in the end face of plate body 1 or so Portion is respectively equipped with left oil-out 3, right oil-out 4, and the upper and lower end face of plate body 1 is plane 5, the upper and lower end face of plate body 1 and left oil-out 3, Outer wall between right oil-out 4 is arcwall face 6;
Left compensating groove 7, right compensating groove 8 are interval with plate body between left oil-out 3, right oil-out 4.
Left oil-out 3, right oil-out 4 are symmetrical arranged, and left oil-out 3, right oil-out 4 are semicircular breach.
Left compensating groove 7 is the waist through hole through plate body.
Right compensating groove 8 is the blind slot of kidney-shaped, and blind slot middle part is provided with the unloading hole 9 of biasing, and unloading hole 9 runs through plate body 1.
