Abstract
A transmission mechanism with two hydraulic pumps of a diesel engine is characterized in that the two hydraulic pumps are symmetrically arranged at two ends of a central shaft of a same gear, and rolling bearings are arranged on two sides of the gear. The size and the connection mode of the interfaces of the two hydraulic pumps are the same or different. The utility model discloses compact structure, small, the gear atress is balanced, and mechanism long service life, two hydraulic pumps can be respectively or simultaneous working, can satisfy user's multipurpose demand, are particularly useful for the supporting installation of small diesel engine.
Description
Technical field
The utility model relates to a kind of driving mechanism of diesel engine oil hydraulic pump, particularly the driving mechanism of diesel engine biliquid press pump.
Background technique
Oil hydraulic pump is used more and more widely as the executive component in the engineering machinery, and its power source generally is the heart in the engineering machinery a---internal-combustion engine.Along with supporting multipurposeization of engineering machinery and volume miniaturization, require at a kind of mechanically equipped simultaneously biliquid press pump, this proposes new problem just for internal-combustion engine manufacturer.Arrange that on bulky diesel engine biliquid press pump difficulty is less, and arrange that on the little diesel engine of volume the biliquid press pump just faces following big difficulty: in the existing hydraulic pressure installation, an oil hydraulic pump needs the set of gears driving mechanism, because the restriction of diesel-engine body length dimension arranges that the biliquid press pump just must stagger mutually on the spatial position, this not only makes the gear drive complexity, volume increases, and because the one-sided carrying of gear, discontinuity equalization influences working life of driving mechanism.
The model utility content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of compact structure, volume little, and long service life can satisfy the requirement of user's multipurpose, is particularly useful for the biliquid press pump driving mechanism of small volume diesel engine.
The technical solution of the utility model is: diesel engine biliquid press pump driving mechanism, comprise driving gear, rolling bearing and two oil hydraulic pumps, improvements are two ends that two oil hydraulic pumps are symmetricly set on the central shaft of same gear, the both sides of this gear are equipped with rolling bearing.
The interface size and the Placement of above-mentioned two oil hydraulic pumps are identical, also can be inequality; The rolling bearing of gear both sides is bearing on gear chamber, the gear chamber cover.
Above scheme, because two oil hydraulic pumps are symmetricly set on the both sides of same gear, and all there is supporting the gear both sides, not only compact structure, volume are little, and the strength of gear equilibrium, prolong the working life of mechanism.Two oil hydraulic pumps can be worked respectively or work simultaneously, can satisfy user's multipurpose demand, and this mechanism is particularly useful for the supporting installation of small volume diesel engine.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Two oil hydraulic pumps 1 and 2 are symmetricly set on the two ends of the central shaft of gear 4, and its interface size is identical with Placement, are all spline and connect.The both sides of gear 4 all have rolling bearing 3 to be bearing on the gear chamber 5.
