Abstract
The utility model discloses a long-life gear oil pump with a simple and reasonable structure, a high operating efficiency, a low failure rate and a long service life. The gear oil pump comprises a pump casing, a main drive gear shaft, and a driven gear shaft, wherein the main drive gear shaft and the driven gear shaft are arranged in the pump casing through corresponding bearings; the pump casing comprises a main casing and a rear cover; the main casing is an integral main casing comprising a front cover and the pump casing body between the front cover and the rear cover.
Description
Technical field
The utility model relates to a kind of long lifetime gear oil pump for engineering machinery.
Background technique
The gear oil pump that existing loader hydraulic work system master joins is to press gear in the three-body type
OilPump, this kind gear
OilAdvantages such as that although pump has is simple in structure, low cost of manufactures, its rate of fault is relatively high, and failure cause is common to be that the trisome assembly precision is low, and the bearing contamination resistance is low, and discharge was large, fragile in pump used after a period of time.
The model utility content
The purpose of this utility model is the deficiency that exists for prior art, and a kind of long lifetime gear oil pump is provided.This long lifetime gear oil pump is simple and reasonable for structure, high working efficiency, failure rate is low, long service life.
The utility model long lifetime technological scheme of gear oil pump comprises pump case, be located at driving gear shaft and driven gear shaft in the described pump case by corresponding bearing respectively, described pump case comprises main casing and bonnet, and described main casing is one to comprise the integral type main casing of protecgulum and the pump case body between protecgulum and bonnet thereof.
The bearing corresponding with described driving gear shaft and driven gear shaft is the DU bearing respectively.
Described driving gear shaft is Spielpassung with corresponding driving gear shaft DU bearing.
Described driving gear shaft is provided with a block bearing by an end that is provided with spline.
The utility model long lifetime its pump case of gear oil pump divides body component few, and seal point quantity is few, and equipment is simple, the corresponding assembly precision that improved, pollute little, noise is low, energy-conservation, durable.
Description of drawings
Fig. 1 is the utility model long lifetime gear oil pump one example structure schematic representation.
Embodiment
Now by embodiment and accompanying drawing the utility model long lifetime gear oil pump is further specified.
As shown in Figure 1, the pump case of the long lifetime gear oil pump of present embodiment only is made of integral type main casing 1 and bonnet 5, integral type main casing 1 is made an integral body by protecgulum and the pump case body between front/rear cover and is consisted of, driving gear 2 and driven gear 3 are located in the integral type main casing 1 by corresponding DU bearing 6 by corresponding driving gear shaft 2a and driven gear shaft 3a respectively, and driving gear shaft 2a is Spielpassung with the DU bearing 6 of corresponding driven gear shaft 3a; Driving gear shaft 2a by establishing a block bearing 4, the factor of beating of bringing to reduce corresponding transmission unit branch, the rated pressure and the working life that are conducive to improve gear pump between the end that is provided with spline and the integral type main casing 1.
Other modified products based on the technological scheme of this long lifetime gear oil pump all belong to protection domain of the present utility model; Above-described embodiment is not the exhaustive of embodiment of the present utility model.
