Description
Technical field
The utility model relates to tractor part applied technical field, is specifically related to a kind of sealing configuration for tractor gear pump.
Background technique
Tractor is a kind of for drawing and driving Work machine to complete the self-propelled motor machine of every mobile operation, also can fix operation power, its by motor, transmission, walk, turn to, the system such as hydraulic suspension, Power output, electrical instrumentation, riding manipulation and traction or device form; Engine power passes to driving wheel through transmission system, and tractor is travelled, and in actual life, common is all the medium transmitted using balata belt as power, divides the tractors such as agricultural, industry and specific use by function and purposes; Wheeled, crawler, boat tractor and self propelled chassis etc. are divided by structure type.
According to statistics, within 2010, operate steadily in China's tractor market, present many new features, total industrial output value and income from sales reach 348.13 hundred million yuan and 400.23 hundred million yuan respectively, meanwhile, outlet delivery value continues to keep strong growth, and the domestic large and middle tractor market demand continues run at high level, but amplification eases up, demand continues to extend to high-power direction, continue to continue to rise with double-digit amplitude in little market of dragging, and on the other hand, the regional market demand is unbalanced, brand competition is growing more intense, the market concentration improves further, but, be far from reaching demand saturation degree compared with the agriculture developed countries and regions such as America and Europe, in addition, product structure performance backwardness is the ubiquitous problem of China's Tractor Products, technical merit need to improve, due to tractor work under bad environment (sleet, high temperature, moist etc.), so require higher for the component of its composition, as the end cover structure of the gear pump for tractor, end cover structure is by gear pump and the extraneous a kind of design of part carrying out sealing, traditional, end cover structure is complicated and the consumption of production Raw is large, easily there is distortion after Long-Time Service simultaneously, fracture, sealing effect is poor, this have impact on the working efficiency of tractor greatly and there is great potential safety hazard.
Therefore, based on the problems referred to above, the utility model provides a kind of sealing configuration for tractor gear pump.
Model utility content
Model utility object: the purpose of this utility model provides a kind of sealing configuration for tractor gear pump, solve existing gear pump cover complex structure and to produce Raw consumption large, easily there is the problem of being out of shape, rupturing, by project organization, the saving raw materials of advantages of simple, and improve assembling after sealing tightness, stop security hidden trouble, be convenient to simultaneously install and demolition and maintenance.
Technological scheme: a kind of sealing configuration for tractor gear pump; comprise gear pump body; and the many groups positioning hole be arranged on gear pump body; and be arranged on the intrinsic circular groove of gear pump; and be symmetricly set on circular groove both sides positioning groove, and be arranged on the attachment hole between many group positioning holes, and be arranged on gear pump body interior and connect protection case by attachment hole; wherein, safety cover shell structure and circular groove structure match.
The technical program, described gear pump body is irregular cycle.
The technical program, described gear pump body, organize positioning hole, circular groove, positioning groove and attachment hole more and to be formed in one structure.
The technical program, the described sealing configuration for tractor gear pump also comprise be arranged on gear pump body and for connect gear pump body, protection case spacing hole.
Compared with prior art, the beneficial effect of a kind of sealing configuration for tractor gear pump of the present utility model is: 1, its rational in infrastructure simple, be convenient to install and safeguard, save raw materials; Utilize gear pump body to be connected with protection case when 2, using and seal protection is carried out to gear pump; assembled fast by the positioning hole on gear pump body, circular groove and positioning groove during installation; the gear pump cover agent structure that this structural integrity is shaping, be convenient to production and processing, not yielding and fracture and with protection case be combined good airproof performance.Simultaneously the utility model cost of production low, easily promote.
Accompanying drawing explanation
Fig. 1 is a kind of sealing configuration plan view for tractor gear pump of the present utility model;
Fig. 2 is a kind of sealing configuration sectional view for tractor gear pump of the present utility model;
Fig. 3 is a kind of sealing configuration worm's eye view for tractor gear pump of the present utility model;
Wherein, in figure, sequence number is as follows: 1-gear pump body, 2-many groups positioning hole, 3-circular groove, 4-positioning groove, 5-attachment hole, 6-protect case, 7-spacing hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
A kind of sealing configuration for tractor gear pump as shown in figures 1 and 3; comprise gear pump body 1; and the many groups positioning hole 2 be arranged on gear pump body 1; and the circular groove 3 be arranged in gear pump body 1; and be symmetricly set on circular groove 3 both sides positioning groove 4, and be arranged on the attachment hole 5 between many group positioning holes 2, and be arranged on gear pump body 1 inside and connect protection case 6 by attachment hole 5; wherein, case 6 structure and circular groove 3 structure is protected to match.
Have preferred further, gear pump body 1 is irregular cycle, and itself and tractor gear pump are installed fixing-assembly structure and matched; Gear pump body 1, many group positioning hole 2, circular groove 3, positioning groove 4 and attachment hole 5 are formed in one structure, are convenient to processing and not yielding, wear-resisting; Also comprising for the sealing configuration of tractor gear pump as shown in Figure 2 and be arranged on gear pump body 1 and spacing hole 7 for connecting gear pump body 1, protection case 6, being bolted location for strengthening gear pump body 1 and protection case 6 connective stability.
Embodiment
Further as shown in Figure 1, first gear pump body 1 is connected by attachment hole 5 with protection case 6 during assembling, undertaken further fastening by spacing hole 7 again, then the sealing configuration after assembling is connected with gear pump scaffold fixed structure, located by positioning groove 4, tighten finally by the positioning hole 2 on gear pump body 1; This sealing configuration, it is easy to assembly, rational in infrastructure, reduce production and processing raw material consumption and without distortion, phenomenon of rupture appearance, effectively seal protection is carried out to gear pump, improves the working efficiency of tractor, reduce the maintenance cost of user.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
