Abstract
The utility model relates to a goat technical field especially relates to a goat duplex bearing supports radial piston pump, including the pump body, pump cover, connector, cylinder body, preceding support bearing, back support bearing, flow distribution shaft, plunger, stator and bearing seal, preceding support bearing installs between cylinder body, connector and the flow distribution shaft, back support bearing installs the cylinder body with between the flow distribution shaft, flow distribution shaft and stator are installed in the pump body, the plunger is installed in the cylinder body, connector and cylinder body are through intersect cross head realization flexible coupling separately. The utility model discloses in start working when rotatory as radial piston pump, owing to the eccentric reason of stator can produce pressure differential in the cylinder body, pressure differential is born by two support bearing the effort of cylinder body is direct, has avoided cylinder body and flow distribution shaft to contact, the cylinder body can not produce wearing and tearing, the effectual life -span of improving radial piston pump.
Description
Technical field
This utility model relates to goat technical field, particularly relates to a kind of goat duplex bearing and supports radial plunger pump.
Background technology
At present, the radial plunger pump used in electrohydraulic switch machine, its cylinder body directly supports by pintle, when radial plunger pump starts to rotate, pressure reduction can be produced in cylinder body, the active force that high pressure side produces makes low-pressure side cylinder inner bore and pintle friction, if things go on like this can aggravate the partial wear of cylinder inner bore, increases leakage rate, reduce the volumetric efficiency of radial plunger pump, meanwhile, the break flour that abrasion produces can aggravate the abrasion of other moving components in the pump housing, reduces the service life of radial plunger pump.
Utility model content
The purpose of this utility model is in that to overcome the deficiency of above-mentioned technology, and provides a kind of goat duplex bearing to support radial plunger pump, overcomes the impact that cylinder body brings with pintle abrasion.
This utility model is for achieving the above object, by the following technical solutions: a kind of goat duplex bearing supports radial plunger pump, it is characterized in that: include the pump housing, pump cover, connector, cylinder body, front support bearing, rear support bearing, pintle, plunger, stator and axle envelope, described front support bearing is arranged on described cylinder body, between connector and pintle, described rear support bearing is arranged between described cylinder body and described pintle, described pintle and stator are arranged in the pump housing, described plunger is arranged in cylinder body, described connector realizes being flexible coupling by respective cross head with cylinder body. the cylinder body rotated is arranged on pintle by two spring bearings, it is to avoid cylinder body contacts with pintle, and cylinder body will not produce to wear and tear.
Described axle envelope is arranged in pump cover, and described pump cover is connected with the described pump housing.
The beneficial effects of the utility model are: in this utility model when radial plunger pump starts working rotation, owing to stator bias reason can produce pressure reduction in cylinder body, the active force of cylinder body is directly born by pressure reduction by two spring bearings, avoid cylinder body to contact with pintle, cylinder body will not produce abrasion, effectively raises the life-span of radial plunger pump.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Detailed description of the invention of the present utility model is described in detail below in conjunction with accompanying drawing and preferred embodiment. As shown in Figure 1, a kind of goat duplex bearing supports radial plunger pump, 9 are sealed including the pump housing 1, pump cover 2, connector 3, cylinder body 4, front support bearing 10, rear support bearing 5, pintle 6, plunger 7, stator 8 and axle, described front support bearing is arranged between described cylinder body, connector and pintle, described rear support bearing is arranged between described cylinder body and described pintle, described pintle and stator are arranged in the pump housing, described plunger is arranged in cylinder body, and described connector realizes being flexible coupling by respective cross head with cylinder body. Described axle envelope is arranged in pump cover, and described pump cover is connected with the described pump housing.
In this utility model when radial plunger pump starts working rotation, owing to stator bias reason can produce pressure reduction in cylinder body, the active force of cylinder body is directly born by pressure reduction by two spring bearings, avoid cylinder body to contact with pintle, cylinder body will not produce abrasion, effectively raises the life-span of radial plunger pump.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, under the premise without departing from this utility model principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
