Abstract
The utility model provides an integrated generator front end cap which comprises a front end cap body, and further comprises a machine oil pump and a crank shaft front oil seal, wherein the front end cap body, the machine oil pump and the crank shaft front oil seal are integrated and connected together. The integrated generator front end cap has the beneficial effects that since the front end cap body, the machine oil pump and the crank shaft front oil seal are integrated, thereby improving the production speed of generator plants, and lowering production cost. In addition, since a new seal structure and a decompression valve structure are adopted, seal is led to be firmer, and decompression is more stable.
Description
[technical field]
The utility model relates to the engine manufacturing technology field, particularly a kind of integrated engine front cover.
[background technique]
What the front cover of conventional engines mostly adopted is, the structure of front cover, oil pump and bent axle Front oil seal separated type, so not only waste the installation time of enginepiston, can't control the assembly quality of part well, the purchase cost of part also can increase simultaneously.The front cover of conventional engines adopts the gasket seal mode, and the sealing effect of this mode is also unreliable, and the phenomenon of leakage of oil takes place in the motor using process easily, influences the normal use of motor.
[model utility content]
In order to solve existing technical problem, the utility model provides a kind of integrated engine front cover, has improved the productive temp of enginepiston, has reduced cost of production.
The utility model solves existing technical problem, a kind of integrated engine front cover is provided, comprise the front end lid, this integrated engine front cover also comprises oil pump and bent axle Front oil seal, and described front end lid, described oil pump are integrated and connected with described bent axle Front oil seal and are in the same place.
The utility model further improves:
The described front end lid that links to each other with engine cylinder-body, it is provided with sealing surface or sealer in the contact position.
Described sealing surface or described sealer have 45 degree chamferings.
This integrated engine front cover comprises timing chain, is provided with anti-jump tooth baffle plate near described timing chain.
Described oil pump comprises Decompression valves, and described Decompression valves comprises two relief holes.
Described Decompression valves comprises pressure releasing valve core, and described two relief holes set up the both sides of this pressure releasing valve core separately.
Described relief hole is the enlarging type.
Described Decompression valves is provided with bolt screens mechanism.
Compared to prior art, the beneficial effects of the utility model are: owing to adopt the integral structure of front end lid, oil pump and bent axle Front oil seal, thus improved the productive temp of enginepiston, reduced cost of production.In addition, owing to adopt new sealing configuration and pressure-relief valve structure, make sealing more firm, pressure release is more steady.
[description of drawings]
Fig. 1 is the structural representation of the utility model integrated engine front cover;
Fig. 2 is the internal structure schematic representation of the described integrated engine front cover of Fig. 1;
Fig. 3 is the chamfering schematic representation of described front cover sealing surface;
Fig. 4 is the structural representation of described two relief holes.
[embodiment]
Below in conjunction with description of drawings and embodiment the utility model is further specified.
As shown in Figures 1 to 4, a kind of integrated engine front cover comprises front end lid 1, oil pump 2 and bent axle Front oil seal 3, and described front end lid 1, described oil pump 2 are integrated and connected with described bent axle Front oil seal 3 and are in the same place, and promptly adopt aluminum alloy material die casting to form.Adopt after the integral structure, save over front end lid 1, oil pump 2 and bent axle Front oil seal 3 separate type must assemble the time of assembling, and guaranteed the structure degree of adaptability.
In addition, the described front end lid 1 that links to each other with engine cylinder-body, it is provided with sealing surface or sealer 4 in the contact position, guarantee the sealability of front cover, solved existing sealing effect poor reliability, the phenomenon of leakage of oil takes place in the motor using process easily, so that influence the normal use of motor.Particularly, described sealing surface or described sealer have 45 degree chamferings, as shown in Figure 3, and to improve its sealability.
This integrated engine front cover comprises timing chain 5, is provided with anti-jump tooth baffle plate 6 near described timing chain 5, thereby improves the working stability of timing chain.
Described oil pump 2 comprises Decompression valves, described Decompression valves comprises two relief holes 7, this two relief hole 7 is different fully with existing single relief hole effect, existing single relief hole, pressure releasing valve core can be subjected to the influence of angular force during its pressure release, cause Decompression valves to be easy to wearing and tearing, thereby make the fit up gap between pressure release valve pocket and the spool increase, cause the oil pump cisco unity malfunction; After the utility model adopted two relief holes, the pressure releasing valve core both sides are stressed evenly can not to produce deflection, has reduced the occurrence probability of eccentric wear, has guaranteed the long-term proper functioning of oil pump.
Described once more relief hole is the enlarging type, as shown in Figure 4, has reduced the pressure release resistance, and it is excessively smooth-going to make that fluid flows, and can not produce recoil force, makes the oil pump pressure release remain the stable operation performance.In addition, described Decompression valves is provided with bolt screens mechanism 8, replaces jump ring screens in the past, makes structure more stable, is not easy to produce to come off, and further guarantees the machine oil pump performance.
The utility model is owing to adopt the integral structure of front end lid, oil pump and bent axle Front oil seal, thereby improved the productive temp of enginepiston, reduced cost of production.In addition, owing to adopt new sealing configuration and pressure-relief valve structure, make sealing more firm, pressure release is more steady.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
