Abstract
The utility model belongs to hydraulic element, in particular to a kind of bicircular arcs compensating groove structure gear pump pump housing, the pump housing (1) is respectively equipped with driving gear seat ring (1-1), driven gear seat ring (1-2), high pressure side (1-4), low voltage side (1-5), in deflection, low voltage side (1-5) place is provided with compensating groove (1-3), be partial to high pressure side (1-4) at compensating groove (1-5) and be provided with circular arc relief grooves one (1-6) near the position at driving gear seat ring (1-1) place, be partial to high pressure side (1-4) at compensating groove (1-3) and be provided with circular arc relief grooves two (1-7) near the position at driven gear seat ring (1-2) place, the bicircular arcs compensating groove structure gear pump pump housing is owing to having circular arc relief grooves in the high pressure side of compensating groove near driving gear seat ring place and driven gear seat ring place, effectively can solve the entrap phenomenon of gears meshing, the vibration produced when decreasing gears meshing, thus reduce the noise of gear pump.
Description
Technical field
The utility model belongs to hydraulic element, particularly a kind of bicircular arcs compensating groove structure gear pump pump housing.
Background technique
Along with the develop rapidly of advanced manufacturing technology, people are also improving constantly the requirement of gear pump low noise, hydraulic gear pump is a kind of positive displacement liquid pump, its kind is divided into internal messing formula gear pump and outer gearing formula gear pump, and outer gearing formula gear oil pump has the advantages such as structure is simple, good from absorption, anti-pollution ability is strong, the life-span is long by means of it, enjoy concern and the favor of people, its deficiency be export flow pulsation, pressure pulsation and noise larger.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of structure simple, can reduce vibration, reduce the bicircular arcs compensating groove structure gear pump pump housing of noise.
The technological scheme that the utility model technical solution problem adopts is: the bicircular arcs compensating groove structure gear pump pump housing comprises the pump housing, be characterized in the pump housing being respectively equipped with driving gear seat ring, driven gear seat ring, high pressure side, low voltage side, in deflection, low voltage side place is provided with compensating groove, also be provided with circular arc relief grooves one near the position at driving gear seat ring place in compensating groove deflection high pressure side, be also provided with circular arc relief grooves two near the position at driven gear seat ring place in compensating groove deflection high pressure side.
The beneficial effects of the utility model are: the bicircular arcs compensating groove structure gear pump pump housing is owing to having circular arc relief grooves in the high pressure side of compensating groove near driving gear seat ring place and driven gear seat ring place, effectively can solve the entrap phenomenon of gears meshing, the vibration produced when decreasing gears meshing, thus the noise reducing gear pump.
