Abstract
The utility model relates to a kind of gear pump combined type bearing, comprise bearing body, this bearing body comprises bearing inner race, bearing outer ring and rolling element, described rolling element is arranged on retainer, rolling element is arranged between bearing outer ring and bearing inner race by retainer, the outer surface of the bearing outer ring of described bearing body is provided with gear, the shaft hole inner wall of described gear is fixedly connected with bearing outer ring, described gear external frame is provided with the gear teeth, be provided with teeth groove between described adjacent teeth, described Gear center is provided with axis hole.The utility model, by bearing and gear being wholely set, is installed simple and convenient, and in the working procedure of planetary gear pump, driving gear accelerates instantaneously and moment impact disengages large torsion to drive multiple driven gear.
Description
Technical field
The utility model relates to gear pump part field, and refer in particular to a kind of combined type bearing on gear pump, this bearing and gear link together jointly.
Background technique
Gear pump is a kind of is the device of hydraulic energy by changes mechanical energy, and it provides the liquid with certain pressure and flow for hydraulic system, is the important component part of hydraulic system.Gear pump relies on the swept volume formed between pumping cylinder and engaging gear to change and the mobile rotary pump carried liquid or make it supercharging, it forms two enclosed spaces by two gears, the pump housing and front and rear covers, when pinion rotation, the volume in space of side of being out of gear is large from little change, form vacuum, sucked by liquid, liquid from diminishing greatly, and is clamp-oned in pipeline and is gone by the volume in the space of gears meshing side.
When gear pump works, run up between driving gear and driven gear, need to use bearing, but current bearing and gear arrange separately, for planetary gear pump, driving gear rotates and then drives other multiple driven gears, so just makes gear be difficult to rotate together, sometimes even can damage drive motor.
Model utility content
The utility model, in order to overcome deficiency of the prior art, provides a kind of gear pump combined type bearing, improves the using effect of bearing and gear.
The utility model is achieved through the following technical solutions:
A kind of gear pump combined type bearing, comprise bearing body, this bearing body comprises bearing inner race, bearing outer ring and rolling element, described rolling element is arranged on retainer, rolling element is arranged between bearing outer ring and bearing inner race by retainer, the outer surface of the bearing outer ring of described bearing body is provided with gear, and the shaft hole inner wall of described gear is fixedly connected with bearing outer ring.
As optimal technical scheme of the present utility model, described gear external frame is provided with the gear teeth, is provided with teeth groove between described adjacent teeth, and described Gear center is provided with axis hole.
As optimal technical scheme of the present utility model, described bearing body is roller bearing.
As optimal technical scheme of the present utility model, described gear is spur gear.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by being wholely set bearing and gear, install simple and convenient, in the working procedure of planetary gear pump, driving gear accelerates instantaneously and moment impact disengages large torsion to drive multiple driven gear.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-bearing body; 2-bearing inner race; 3-bearing outer ring; 4-rolling element; 5-gear; The 6-gear teeth; 7-teeth groove.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of gear pump combined type bearing, comprise bearing body 1, this bearing body 1 comprises bearing inner race 2, bearing outer ring 3 and rolling element 4, described rolling element 4 is arranged on retainer, rolling element 4 is arranged between bearing outer ring 3 and bearing inner race 2 by retainer, the outer surface of the bearing outer ring 3 of described bearing body 1 is provided with gear 5, the shaft hole inner wall of described gear 5 is fixedly connected with bearing outer ring 3, described gear 5 external frame is provided with the gear teeth 6, be provided with teeth groove 7 between described adjacent teeth 6, described gear 5 center is provided with axis hole.By bearing and gear being wholely set, install simple and convenient, in the working procedure of planetary gear pump, driving gear accelerates instantaneously and moment impact disengages large torsion to drive multiple driven gear.
In the present embodiment, described bearing body 1 is roller bearing, and described gear 5 is spur gear.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
