Abstract
A novel two-section gear pump comprises a front cover, a pump body and a rear cover, wherein the front cover and the pump body are of an integral structure; and the rear cover is connected with the pump body through a screw. The structure of a gear oil pump is more compact, the overall strength of the gear oil pump is enhanced, the service life of the gear oil pump is prolonged, the fault point of the gear oil pump can be reduced, precision in machining and installation positioning is improved, the sealing performance and the working pressure of the gear pump are improved, the leakage is reduced, the component number is reduced, the machining procedure is simplified, the machining cost is reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of Hydraulic power units, specifically, relates to a kind of novel two-part gear pump.
Background technique
In the prior art, gear pump all is traditional three stage structure, i.e. protecgulum, the pump housing, bonnet.The physical dimension of this kind structure gear oil pump is bigger, and the bulk strength of gear oil pump is not high enough, and working life is short, and the fault point is many, and sealing effect is poor.
The model utility content
To above-mentioned deficiency of the prior art, the utility model provides a kind of compact structure, and the bulk strength of gear oil pump increases, a kind of novel two-part gear pump that has prolonged gear oil pump working life.
The technological scheme that the utility model is taked is:
A kind of novel two-part gear pump comprises: protecgulum, the pump housing, bonnet, the said protecgulum and the pump housing are structure as a whole.
Said bonnet is connected with the pump housing through screw.
The beneficial effect of the relative existing technology of the utility model:
The gear oil pump structure of the utility model is compact more, and the bulk strength of gear oil pump increases, and has prolonged the working life of gear oil pump; Can reduce the fault point of gear oil pump, increase the precision of processing and installing and locating, improve the sealability and the working pressure of gear pump; Reduce seepage, reduced number of spare parts, simplified manufacturing procedure; Reduce processing cost, improved manufacturing efficiency.
Description of drawings
Fig. 1 is existing gear pump structure schematic representation;
Fig. 2 is the structural representation of the utility model.
Critical piece symbol description in the accompanying drawing:
Among the figure:
