Abstract

The utility model belongs to hydraulic elements, and particularly relates to a gear pump with a cover for a high-pressure body. The gear pump comprises a front cover (1), a locating pin (2), a side plate (4), a base plate (5), a steel-backed bearing (6), a drive gear (7), a driven gear (8), an antifriction bearing (11), an inner seal barrier strip (9), an outer seal barrier strip (10), a reinforced seal (12) and a clamp spring (13) for a hole, wherein a pump body and a rear cover are combined into a conjoined pump cover (3), the gear pump with the cover for the high-pressure body combines the rear cover with the pump body into a whole body so that the processing is more convenient, the sealing between the pump body and the rear cover is omitted, leakage points are reduced, the gear pump is not easy to leak, the whole strength is increased, the pass percent is improved, and the service life is prolonged.

Description

The high pressure body even covers gear pump

Technical field

The utility model belongs to hydraulic element, and particularly a kind of high pressure body even covers gear pump.

Background technique

Existing gear pump generally all is three body structures, and just gear pump is made up of protecgulum, the pump housing, bonnet, and the gear pump manufacturing procedure of this three body structures is many, and leakage point is many, and difficulty of processing is big, and bulk strength is low, and the sealing level is many, and up-to-standard rate is low, and processing cost is high.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned technical deficiency, provides a kind of bonnet and the pump housing to be combined as a whole, and is easy to process, and the high pressure body that is difficult for revealing even covers gear pump.

The technological scheme that the utility model technical solution problem adopts is: the high pressure body connects and covers gear pump and comprise that protecgulum, locating stud, side plate, backing plate, steel-backed bearing, driving gear, driven gear, rolling bearing, interior sealing blend stop, external sealed blend stop, reinforced seal, hole use jump ring, is characterized in the pump housing and bonnet are combined into disjunctor pump housing pump cover.

The beneficial effect of the utility model is: the high pressure body even covers gear pump the bonnet and the pump housing is combined as a whole, and makes processing more convenient, has saved the sealing between the pump housing and the bonnet; Reduced the leak point, be difficult for revealing, bulk strength increases; Up-to-standard rate improves, and increases working life.

Description of drawings

Specify with embodiment below in conjunction with accompanying drawing.

Fig. 1 is that the high pressure body even covers the gear pump structure sectional view.

Among the figure, the 1-protecgulum; The 2-locating stud; 3-disjunctor pump housing pump cover; The 4-side plate; The 5-backing plate; The 6-steel-backed bearing; The 7-driving gear; The 8-driven gear; Sealing blend stop in the 9-; 10-external sealed blend stop; The 11-rolling bearing; The 12-reinforced seal; 13-uses jump ring in the hole.

Embodiment

Embodiment; With reference to accompanying drawing 1; It is that the bonnet and the pump housing are combined into disjunctor pump housing pump cover 3 that the high pressure body even covers gear pump, insert one cover needle bearing 11, following insert one cover steel-backed bearing 6 above protecgulum 1 right-hand member, upper and lower each insert one cover steel-backed bearing 6 in the disjunctor pump housing pump cover 3.Install driving gear 7 in the needle bearing 11 of insert and in the steel-backed bearing 6 of disjunctor pump housing pump cover 3 interior top inserts in the protecgulum 1; Install driven gear 8 in two of the insert cover steel-backed bearings 6 below in protecgulum 1 and the disjunctor pump housing pump cover 3, driving gear 7 is connected by meshing transmission with driven gear 8.Driving gear 7 and driven gear 8 both sides suit side plates 4; Side plate 4 outsides are set with backing plate 5, and sealing blend stop 9 and external sealed blend stop 10 connect with bolt between protecgulum 1 and this pump cover of disjunctor 3 in loading between side plate 4 and the backing plate 5; With locating stud 2 location; With interior sealing blend stop 9 and 10 sealings of external sealed blend stop,, spacing with jump ring 13 between protecgulum 1 and the driving gear 7 with the hole with reinforced seal 12 sealings.
