Description
Technical field
The present invention relates to a kind of engine lubrication system parts, particularly to the lubricating oil pump of a kind of band idle gear.
Background technology
Existing huge discharge lubricating oil pump is typically mounted in the machine oil shell below engine crankcase, passes through engine crankshaft
On gear drive transmission gear of engine oil pump, owing to engine crankcase is very big, the centre-to-centre spacing ratio of lubricating oil pump power transmission shaft and bent axle
Relatively big, on the premise of gear ratio determines, if simple relying on increases transmission gear of engine oil pump and the gear diameter on bent axle
Mate centre-to-centre spacing, the gear on bent axle certainly will be caused excessive with transmission gear of engine oil pump, so can increase cost, additionally start
Machine does not has the gear that enough space placement diameter are the biggest yet.So must increase between transmission gear of engine oil pump and crankshaft toothed wheel
Add an idle gear could be delivered on transmission gear of engine oil pump by the gear driving force on bent axle, the most both can reduce cost,
Also engine structure can be made compacter, but following weak point can be produced again simultaneously: huge discharge lubricating oil pump operationally load
Very big, need the machine oil of circulation be lubricated and dispel the heat between idle gear axis hole and idler shaft, idle gear axis hole and idler shaft it
Between without good lubrication and heat radiation, the fault such as idle gear axis hole and idler shaft can be caused to burn to death, seize, electromotor works
Time lubrication, heat radiation use machine oil be all lubricating oil pump conveying, once idle gear can not work, and lubricating oil pump also can stop work
Making, whole electromotor is not as have oil lubricating, heat radiation and the phenomenon of scuffing of cylinder bore, bearing liner burnout occurs.
Summary of the invention
The technical problem to be solved in the present invention is to provide the machine of a kind of band idle gear that can guarantee that idle gear functional reliability
Oil pump.
In order to solve above-mentioned technical problem, the present invention adopts the following technical scheme that the lubricating oil pump of a kind of band idle gear, including
Pump cover assembly, pump assembly, travelling gear, idle gear, idler shaft, described pump assembly is provided with oil road and idler shaft is installed
Hole, the hole wall of described idler shaft installing hole is provided with lubrication oil leak hole, the other end of this lubrication oil leak hole and described oil road phase
Logical；Described idle gear is provided with axis hole, equipped with lining in described axis hole；Described idler shaft is multidiameter, including thrust button, big axle
Section, little shaft part and threaded shaft section, the biggest shaft part is provided with lubrication groove, and little shaft part is provided with annular oil groove, and described idler shaft also sets
There are connection lubrication groove and the idler shaft oil leak hole of annular oil groove；The big shaft part of described idler shaft is through the lining axle in idle gear
Hole, little shaft part passes through nut screwing clamping through the idler shaft installing hole on pump assembly, threaded shaft section, makes idle gear be fixed on the pump housing
On assembly, described idler shaft oil leak hole is connected with the lubrication oil leak hole on pump assembly by annular oil groove.
In technique scheme, due in the axis hole of idle gear equipped with lining, so rely on lining axis hole big with idler shaft
Shaft part contacts, and owing to the bronze powder in lagging material has good self-lubricating function, can improve the wearability of axis hole；Oil road
In hydraulic oil by lubrication oil leak hole, hydraulic oil is delivered in the annular oil groove of idler shaft, annular oil groove is further through idle pulley
Hydraulic oil is delivered to the lubrication groove on the big shaft part of idler shaft by axle oil leak hole, is full of the hydraulic oil from oil road in lubrication groove,
Hydraulic oil continues to walk toward idle gear pillow block two ends by the gap between idler shaft and lining axis hole, both can lubricate axis hole with lazy
The big shaft part of wheel shaft, can make again machine oil out return to, machine oil shell, be achieved in that lazy tooth from idle gear two pillow block face leakage
Oil circulation circulation between axle hole and idler shaft such that it is able to the continual idle gear rotating big load provides profit
Sliding, heat radiation, it is to avoid the faults such as idle gear axis hole burns to death with idler shaft, seize.
The further technical scheme of the present invention is: be equipped with drain pan in the pillow block both ends of the surface of described idle gear.
Preferably, the pillow block both ends of the surface of described idle gear are respectively provided with four uniform drain pans.
Owing to idle gear shaft you face is provided with drain pan, machine oil between axis hole and the big shaft part of idler shaft so can be accelerated
Flow velocity, make lubrication, radiating effect more preferable.Decrease idle gear shaft you face and idler shaft thrust button and pump assembly simultaneously
Contact area, reduce frictional force, when frictional force reduces the biggest load, produced heat can be less, and flows out from drain pan
Come hydraulic oil can also lubricate the rubbing surface between idle gear shaft you face and idler shaft thrust button and and pump assembly between
Rubbing surface, this makes it possible to preferably improve idle gear maintainability, reduce because idle gear fault cause lubricating oil pump
Cisco unity malfunction causes engine lubrication, heat radiation is not enough and the phenomenon of scuffing of cylinder bore, bearing liner burnout occurs.
Preferably, described idler shaft oil leak hole is the inclined hole that angle of inclination is identical, described idler shaft with lubrication oil leak hole
Oil leak hole is located along the same line after connecting with lubrication oil leak hole.So can allow hydraulic oil circulation swimmingly.
Preferably, described lubrication groove is annular.
Preferably, described idler shaft is provided with loss of weight counterbore.
