Description
Technical field
The utility model is about engine art, especially with regard to a kind of mounting structure of helical teeth wheel drive oil pump.
Background technique
Available engine is to realize that bigger oil pump sprays pressure, using gear driving injection pump rotation, while using helical teeth
Wheel construction is to realize that gear engages more smooth realization noise reduction purpose.Oil pump drive shaft 11 uses the axis of rolling when fixing on the pump housing
It holds 13 and is used to support fixation.
As shown in Fig. 2, existing oil pump is fixed on engine, perfect condition oil pump drive shaft keep water when operating
Flat, real work situation is due to helical gear stress and bearing has and will appear the incomplete centering of drive shaft in certain interval operation process
Situation.The incomplete centering of drive shaft, driving axial bearing applies the component along drive shaft axial direction, axis in rotary course
Holding fixed form is to be packed into oil sealing disk 12 for interference fit, and when the component of drive shaft overcomes interference power, bearing both can be from oil sealing disk
Abjection causes bearing to fall apart to break pump body without being supported and fixed on the change of team of oil pump inward turning after bearing abjection.
The information disclosed in the background technology section is intended only to increase the understanding to the general background of the utility model, and
It is not construed as recognizing or implying in any form that information composition is already known to those of ordinary skill in the art existing
Technology.
Utility model content
The purpose of this utility model is to provide a kind of mounting structures of simple and reasonable helical teeth wheel drive oil pump, should
The mounting structure of helical teeth wheel drive oil pump increases thrust chip architecture between bearing and the pump housing, and thrust plate plays protection after shaft strength
Effect prevents bearing from continuing to be detached from oil sealing disk, to prevent the unstable fragmentation risk of bearing operation.
To achieve the above object, the utility model provides a kind of mounting structure of helical teeth wheel drive oil pump, comprising: pump
Body, two sides offer drive shaft perforation, and drive shaft perforation is used as bearing block；Bearing is two, and one is directly laid
In the drive shaft perforation of pump housing side, another is laid in the drive shaft perforation of the pump housing other side by oil sealing disk；Driving
Axis, both ends pass through two bearing supports in the drive shaft perforation of the pump housing respectively；Helical gear is laid in the drive shaft
One end；And thrust plate, it is laid between the bearing and the pump housing, prevents bearing to be detached from oil sealing disk from inside.
In a preferred embodiment, bearing and oil sealing disk are interference fitted.
In a preferred embodiment, bearing is rolling bearing.
Compared with prior art, the mounting structure of helical teeth wheel drive oil pump according to the present utility model has following beneficial to effect
Fruit: in a kind of helical teeth wheel drive oil pump structure oil pump internal bearings rotary course of existing scheme due to drive shaft operation in can not be complete
Full centering causes a part of component to loosen bearing from oil sealing disk, and existing scheme increases thrust chip architecture between bearing and the pump housing,
Thrust plate plays a protective role after shaft strength, prevents bearing from continuing to be detached from oil sealing disk, to prevent bearing operation unstable broken
Split risk.
Detailed description of the invention
Fig. 1 is the schematic diagram according to the mounting structure of the helical teeth wheel drive oil pump of the utility model first embodiment.
Fig. 2 is the schematic diagram of the mounting structure of existing helical teeth wheel drive oil pump.
Specific embodiment
With reference to the accompanying drawing, specific embodiment of the present utility model is described in detail, it is to be understood that this is practical
Novel protection scope is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
As shown in Figure 1, according to the specific packet of the mounting structure of the helical teeth wheel drive oil pump of the preferred embodiment in the utility model
It includes: drive shaft 1, oil sealing disk 2, bearing 3, thrust plate 4, the pump housing 5 and helical gear 6.Wherein, helical gear 6 is laid in the one of drive shaft 1
End, drive shaft 1 are fixed when fixing on the pump housing 5 using the support of bearing 3.The fixed form of bearing 3 is that interference fit is packed into oil sealing
Disk 2, and increase thrust plate 4 between bearing and the pump housing, thrust plate plays a protective role after shaft strength, prevents bearing from continuing to take off
From oil sealing disk, to prevent the unstable fragmentation risk of bearing operation.
Specifically, the lower part two sides of the pump housing 5 offer drive shaft perforation, and drive shaft perforation is used as bearing block, uses
In passing through bearing 3, drive shaft 1 is set.
Bearing 3 is two, and one is directly laid in the drive shaft perforation of 5 side of the pump housing, another passes through 2 cloth of oil sealing disk
It is located in the drive shaft perforation of 5 other side of the pump housing.
Preferably, bearing 3 and oil sealing disk 2 are interference fitted.
Preferably, bearing 3 is rolling bearing.
The both ends of drive shaft 1 pass through two bearings 3 respectively and are supported in the 5 drive shaft perforation of the pump housing.
Helical gear 6 is laid in one end of drive shaft 1, can be realized bigger oil pump using gear driving injection pump rotation and sprays
Pressure, while gear can be realized using helical teeth wheel construction and engage more smooth realization noise reduction purpose.But oil pump, which is fixed on, to be started
On machine, perfect condition oil pump drive shaft keep horizontal when operating, real work situation is due to helical gear stress and bearing has
It will appear the incomplete centering situation of drive shaft in certain interval operation process.Drive shaft incomplete centering drives in rotary course
Axial bearing applies the component along drive shaft axial direction.
Thrust plate 4 is laid between bearing 3 and the pump housing 5, i.e., thrust plate 4 is laid in the 5 drive shaft perforation of the pump housing, from
Inside prevents bearing from continuing to be detached from oil sealing disk, plays a protective role.
To sum up, the mounting structure of the helical teeth wheel drive oil pump increases thrust chip architecture, shaft strength between bearing and the pump housing
Thrust plate plays a protective role afterwards, prevents bearing from continuing to be detached from oil sealing disk, to prevent the unstable fragmentation risk of bearing operation.
