Description

A kind of inclined disc type hydraulic plunger motor or pump for using submerged in water
Technical field
The utility model belongs to Hydraulic Field, more particularly to a kind of inclined disc type hydraulic column Saimaa for using submerged in water Up to or pump, it is adaptable to drive water impeller(As motor)Or driven by water impeller(As pump)Device.
Background technology
Traditional inclined disc type hydraulic plunger motor or pump, its inner body is only to main shaft applying radial load, therefore bearing used Stronger to radial load bearing capacity but poor to the bearing capacity of axial force, product shaft end does not allow to apply axial force(Including drawing Power and thrust)Or only allow to apply less axial force.
Traditional hydraulic clino-axial piston motor or pump, it is internally provided with single or multiple radial thrust bearings, the axle The axial tension that group can bear towards the overhanging direction of main shaft is held, but inside axial thrust can not be born.If in clino-axis type The shaft end of piston motor or pump applies larger pulling force, and the very big axial thrust load that this pulling force is applied to main shaft with plunger is superimposed, The service life of product will be greatly reduced;If applying thrust in its shaft end, this thrust can not be more than plunger to main shaft Axial thrust load, i.e.,:When motor or relatively low pump pressure, larger axial thrust must not be applied in its shaft end, the otherwise power passes through The center-pole being hinged on main shaft compresses cylinder body and valve plate by force, is easily caused center-pole bulb and cylinder body with flow side surface Burn.
Conventional inclined disc type or hydraulic clino-axial piston motor or pump, main shaft rotating seal uses one-way bearing pressure Seal, can only bear internal pressure and can not bear external pressure.
Due to previous reasons, when conventional hydraulic piston motor or pump are used to drive water impeller or by water impeller driving During device, because impeller draining produces larger axial force, and impeller changing force direction can accordingly change axially rearward, therefore should not be by leaf Wheel to be mounted directly on the main shaft of motor or pump, and need to be separately provided impeller axle, support the axle oil-lubricated bearing or water moisten Plain besring, shaft coupling etc..No matter and using oil-lubricated bearing or water lubriucated bearing, its lubricating condition cannot all be submerged with bearing Compared in hydraulic oil, bearing needs to use bigger specification to improve the life-span.This results in apparatus structure complexity, axial dimension Greatly, manufacture and working service are relatively costly.Additionally, because shaft seal can only one-way bearing pressure, exist when being used in deep water Water pours in down a chimney the risk into hydraulic plunger motor or pump inner chamber.
If application publication number is the patent of the A of CN 105697388《Deepwater hydraulic drives water pump》, impeller is installed in pump shaft On, pump shaft is supported by water lubriucated bearing, and pump shaft is by shaft coupling and hydraulic rotating actuator(That is hydraulic motor)Output Axle is connected;Water pump is additionally provided with for water to be caused into the lubrication system that water lubriucated bearing is lubricated.
The content of the invention
The purpose of this utility model is to provide a kind of inclined disc type hydraulic plunger motor or pump for using submerged in water, its Main shaft can bear very big axial tension, can also bear very big axial thrust, for driving water impeller or by draining leaf During the device of wheel drive, water impeller can be mounted directly on its main shaft;Its main shaft rotating seal can with bidirectional bearing, even if It is immersed in deep water and uses, also can effectively separates water and hydraulic oil.
The purpose of this utility model and solve its technical problem underlying using following technical scheme and realize:One kind leaching The inclined disc type hydraulic plunger motor or pump not used in water, including main shaft, rotating seal, housing, swash plate, plunger backhaul machine Structure, plunger, cylinder body, valve plate and end cap, it is characterised in that described main shaft is at least by three coaxial mounted bearings: Bearing A, bearing B and bearing C, at least two bearings are radial thrust bearing in three bearings, and two radial thrust bearings Installation direction is opposite.
There are two bearings to be arranged close to the overhanging end of main shaft in three bearings, and in rotating seal and swash plate Between.
Described rotating seal be both sides can pressure-bearing seal, specifically skeleton-type oil seal or mechanical oil sealing or A combination of both.
Have axial hole and the radial hole connected with axial hole on described main shaft, and radial hole be arranged on rotating seal and Between the bearing A of the rotating seal.
The main shaft uses the stainless steel of seawater corrosion resistance.
The housing, end cap use the stainless steel or bronze material of seawater corrosion resistance, the streamlined design of profile.
The oblique disk structure is used determines angle swash plate or varied angle swash plate.
The plunger return mechanism is using ball pivot backhaul dish structure or determines gap return structures.
The utility model patent has clear advantage and beneficial effect compared with prior art.Can by above technical scheme Know, the utility model patent has advantages below:
1)Very big axial tension can be born on main shaft, very big axial thrust can be also born;Deep water can be immersed in Middle application
2)By setting axial hole and radial hole on main shaft, make fluid that recycle stream is formed in housing chamber using centrifugal force It is dynamic, bearing is cooled down and is rinsed, be conducive to improving bearing life;
3)During for driving water impeller or the device by water impeller driving, directly impeller can be arranged on main shaft, Without setting support shaft, bearing and shaft coupling in addition for impeller, so as to significantly simplify apparatus structure, significantly reduce its axial chi It is very little, reduce manufacturing cost and working service cost.
4)Also water and hydraulic oil can effectively be separated when the seal of bidirectional bearing may insure that product is used in deep water.
