Abstract
The invention discloses a double open type axial clearance compensation high pressure gear pump. An ordinary three-piece gear pump body is insufficient in bearing strength and sealing property. The gear pump comprises a front cover, a pump body, a pair of floating side plates, an E-shaped seal ring, a driving gear, a driven gear and a pair of sliding bearings; the sliding bearings are arranged in the middle of the driving gear and the middle of the driven gear respectively, and the driving gear is in meshing transmission with the driven gear. The floating side plates and the E-shaped seal ring adopt split-type design and are in floating connection with the sliding bearings. The sliding bearings are installed to be higher than a bearing base hole plane. The pump body and a rear cover are integrally designed, and oil leakage points of the ordinary three-piece gear pump body are reduced. By means of the floating side plates and the E-shaped seal ring, the stress conditions of the gears and the floating side plates are optimized. When the gear pump operates at high pressure, the pump body has enough bearing capacity, the stress environment of the parts such as the gears, the floating side plates and the sliding bearings is greatly improved, and the volume efficiency and the overall efficiency are guaranteed.
Description
Technical field
The present invention relates to a kind of two-opening type gear pump, be the gear pump of conjoined structure particularly to a kind of pump housing bonnet.
Background technology
Conventional gear pumps is all based on three-chip type at present, mainly it is made up of protecgulum, the pump housing, bonnet, for preventing three part faying face leakage of oils, exterior seal ring is all used to seal between protecgulum and bonnet and the pump housing, this just precision to big of part, and the quality of sealing member is proposed higher requirement, additionally, owing to the pump housing is individually to bear pressure, so intensity to the pump housing self it is also proposed higher requirement.
Summary of the invention
For the deficiencies in the prior art, the two-opening type axial clearance compensation high-pressure gear pump that the present invention provides a kind of pump housing bonnet to be conjoined structure, with the problem solving common three-chip type gear pump body bearing strength, sealing is not enough, while improving gear pump operating pressure, in turn ensure that volumetric efficiency and aggregate efficiency.
To achieve these goals, the present invention adopts the following technical scheme that
A kind of two-opening type axial clearance compensation high-pressure gear pump, include protecgulum, the pump housing, a pair floating side plate, E RunddichtringO, driving gear, driven gear, pair of sliding bearing, said two sliding bearing is separately positioned in the middle part of driving gear, driven gear, described driving gear, driven gear engaged transmission；Described floating side plate and E RunddichtringO use split-type design, and with sliding bearing floating connection；Described sliding bearing exceeds bearing saddle bore Plane Installation.
The pump housing of the present invention and the integral design of bonnet, decrease the leakage of oil point of common three-chip type.Two floating side plates and split type E RunddichtringO, optimize the stressing conditions of gear and floating side plate.Gear pump is when high-voltage operation, and not only the pump housing has enough bearing capacitys, and the force environment of the parts such as gear, floating side plate and sliding bearing has greatly improvement.While improving gear pump operating pressure, in turn ensure that volumetric efficiency and aggregate efficiency.

Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is further described.
As shown in Figure 1-2, the present invention includes protecgulum 3, the pump housing 10, a pair floating side plate 6, E RunddichtringO 13, driving gear 7, driven gear 8, pair of sliding bearing, sliding bearing uses DU bearing 9, two sliding bearings are separately positioned in the middle part of driving gear 7, driven gear 8, driving gear 7, driven gear 8 engaged transmission.Floating side plate 6 and E RunddichtringO 13 use split-type design, and with sliding bearing floating connection.Sliding bearing exceeds bearing saddle bore Plane Installation.
The pump housing 10 of the present invention is one piece casting part with bonnet, and the fabricated part after processing with the main distinction of other structures is, decreases common three-chip type leakage of oil point.Two floating side plates 6 use split type with E RunddichtringO 13, not only increase floating side plate 6 intensity, and can avoid because of need to milling seal groove brings bottom the pump housing difficulty of processing.
Two sliding bearings exceed bearing saddle bore Plane Installation, not only ensure that the effective bearing area of sliding bearing, gear pair two ends rigid support spacing can be shortened simultaneously, reduce gear deflection deformation under high pressure operating mode, make the bearing capacity of gear pump main parts size be improved.While improving gear pump operating pressure, in turn ensure that volumetric efficiency and aggregate efficiency.Owing to this pumpage is relatively big, its work rated pressure reaches 16MPa, and maximum pressure reaches 20MPa.
