Description
Technical field
The utility model belongs to field of internal combustion engine, is related to a kind of hydraulic pump more particularly to a kind of use for diesel engine hydraulic pump passes
Dynamic output mechanism.
Background technique
With the fast development of Tendency of Agricultural Machinery in China, the demand of tractor is increasing, and tractor power, which increases, to become
Gesture is more and more obvious, it is desirable that big-power tractor hydraulic pump pump oil amount increases therewith, to as hydraulic pump important composition component
More stringent requirements are proposed for hydraulic pump driving output mechanism.Hydraulic oil pump commonly used in the prior art is mostly three modulus hydraulic oil
Pump, three modulus hydraulic oil pump pump oil amounts are difficult to meet the needs of big-power tractor.Therefore, big-power tractor needs assembly four
Modulus hydraulic oil pump.Four modulus hydraulic pump driving output mechanism of ladle type in the prior art is more complicated, cost of manufacture is higher,
Production cycle is longer, can not meet the demand of user.Therefore, new use for diesel engine hydraulic pump driving output mechanism symbol is developed
Close the hope of users.
A kind of utility model patent of State Intellectual Property Office's authorization on 09 19th, 2012: " biliquid press pump of diesel engine
Transmission mechanism ", application No. is: 201220035797.5, notification number are as follows: CN202441487U；Disclose a kind of diesel engine
The transmission mechanism of biliquid press pump, including hydraulic pump gear and hydraulic pump driving axle sleeve, the roller bearings of hydraulic pump gear exist
On housing for timing gear and gear cap；Hydraulic pump gear center have tooth form through-hole, hydraulic pump driving axle sleeve outer surface have with
The tooth form that the tooth form through-hole at hydraulic pump gear center matches, hydraulic pump driving axle sleeve inner hole both ends are equipped with scallop, the tooth
Shape hole is installed by hydraulic pump driving axle；Hydraulic pump driving axle sleeve both ends have outer jump-ring slot, and circlip is mounted in jump-ring slot；Two liquid
Press pump is symmetricly set on the center both ends of hydraulic pump driving axle sleeve.It can be seen that this Double-hydraulic pump drive output mechanism, tie
Structure is more complicated, and cost of manufacture is higher.
Utility model content
It is existing to solve the purpose of this utility model is to provide a kind of new use for diesel engine hydraulic pump driving output mechanism
The problem that hydraulic pump driving output mechanism is at high cost and the production cycle is long realizes that diesel engine hydraulic pump drive output mechanism structure is tight
It gathers, use is reliable and stable, and it is convenient to install and maintain, and reduce costs.
In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of use for diesel engine hydraulic pump driving output
Mechanism, comprising: bolt, hydraulic pump connection counter flange, first bearing, gear chamber, hydraulic pump driving gear, gear chamber cover, the
Two bearings, bearing stop flange；Hydraulic pump connection counter flange and first bearing are coupled, and first bearing is sleeved on gear chamber
On, second bearing is sleeved on gear chamber cover, and hydraulic pump driving gear one end is coupled with first bearing, hydraulic pump driving tooth
The wheel other end is coupled with second bearing, and second bearing is coupled with bearing stop flange.
It is provided with corresponding mounting hole in hydraulic pump connection counter flange and gear chamber, and installation connection is carried out by bolt；
It is provided with corresponding mounting hole on bearing stop flange and gear chamber cover, and installation connection is carried out by bolt.
The beneficial effect that the utility model obtains afterwards by adopting the above technical scheme is: hydraulic pump passes in the utility model structure
Moving gear merges gear drive and internal spline in one, reduces secondary transmission, improves transmission efficiency, compact-sized.Hydraulic pump
Transmission gear connect the reasonable cooperation of counter flange, gear chamber cover and bearing stop flange, side by two bearings with hydraulic pump
Just installation and maintenance, safe and reliable, cost of manufacture is lower.This duplex bearing support hydraulic pressure pump drive gear is compact-sized can
It leans on, efficiently solves the problems, such as that processing cost height and production cycle are long.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of use for diesel engine hydraulic pump driving output mechanism of the utility model；
In figure: 1. bolts, 2. hydraulic pumps connect counter flange, 3. first bearings, 4. gear chambers, 5. hydraulic pump drivings
Gear, 6. gear chamber covers, 7. second bearings, 8. bearing stop flanges.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and embodiments, it is to be understood that the guarantor of the utility model
Shield range is not limited by the specific implementation.
As shown in Figure 1, a kind of use for diesel engine hydraulic pump driving output mechanism, comprising: bolt 1, hydraulic pump connect transition method
Blue 2, first bearing 3, gear chamber 4, hydraulic pump driving gear 5, gear chamber cover 6, second bearing 7, bearing stop flange 8.Wherein,
Hydraulic pump connection counter flange 2 and first bearing 3 are coupled, and are provided in hydraulic pump connection counter flange 2 and first bearing 3
Mutual corresponding mounting hole connect installation with gear chamber 4 by bolt 1；Second bearing 7 and gear chamber cover 6 use bearing after cooperating
Stop flange 8 is limited, and is provided with mutual corresponding mounting hole on bearing stop flange 8 and gear chamber cover 6, and pass through bolt
1 is attached installation；5 both ends of hydraulic pump driving gear are coupled with first bearing 3 and second bearing 7.
When diesel engine works, the crankshaft toothed wheel in gear chamber 4 transmits power to liquid by idle gear and cam shaft gear
Then press pump transmission gear 5 passes through the internal spline and four modulus hydraulic pump spline fitteds of hydraulic pump driving gear 5, makes four moduluses
Hydraulic pump works normally, and meets the mating needs of big-power tractor high-volume hydraulic oil.Hydraulic pump driving can thus be passed through
Gear connects four modulus hydraulic pumps and carries out power transmission, compact-sized reliable, is easy to use maintenance, solves mating high-power drag
The bottleneck problem that machine drawing is at high cost and the production cycle is long.
Situation described in this embodiment is not limited in practical application, all do not depart from the utility model in essence content
Technical solution and improvement, should all fall into the scope of the claims of the utility model.
