Description
Technical field
The utility model relates to a kind of gear pump, relates in particular to a kind of oil transfer gear pump mechanism.
Background technique
Gear pump is a kind of common pump housing equipment.The transmission performance of gear pump and sealability are very important two performance index.Sealing directly has influence on the sealability of gear pump, even affects its working life.Existing gear pump arranges sealing pair in drive shaft end, but because the size deviation of live axle, out of roundness, roughness etc. all can affect its sealability.And adopt screw positioning transmission seat and rotating ring, owing to being hard contact, when service time is long, between rotating ring and stationary ring, will inevitably occur leaking.If can design a kind of can effectively avoiding, leak, guarantee the sealing system of sealing reliability, can address the above problem well.
Model utility content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, can effectively avoid occur leaking and sealing reliable oil transfer gear pump mechanism.
The technological scheme that the utility model adopts is: the utility model comprises motor and the pump housing, in the described pump housing, be provided with a major axis, one end of described major axis is connected by coupling with the output shaft of described motor, on one end being connected with output shaft described motor described major axis, be arranged with sealing seat, described sealing seat comprises the throw-out collar setting gradually, rotating ring, stationary ring and be set on described major axis and be positioned at the spring of described throw-out collar front end, described spring is volute spring, described volute spring fixed cover is located on described major axis, between described throw-out collar and described rotating ring, between described stationary ring and the end cap of the described pump housing, be provided with seal ring I.
Further, the described pump housing comprises cylinder body, is arranged on driving wheel, the follower with described driving wheel engagement, the first end cap, the second end cap in described cylinder body and the minor axis that passes described follower, described major axis, through described driving wheel, is provided with seal ring II between described the first end cap, described the second end cap and described cylinder body.
Further, described seal ring I and described seal ring II by ethylene-propylene-diene monomer glue-line as body, at described the external polytetrafluoroethylene floor that is coated with.
The beneficial effects of the utility model are: because the utility model comprises motor and the pump housing, in the described pump housing, be provided with a major axis, one end of described major axis is connected by coupling with the output shaft of described motor, on one end being connected with output shaft described motor described major axis, be arranged with sealing seat, described sealing seat comprises the throw-out collar setting gradually, rotating ring, stationary ring and be set on described major axis and be positioned at the spring of described throw-out collar front end, described spring is volute spring, described volute spring fixed cover is located on described major axis, between described throw-out collar and described rotating ring, between described stationary ring and the end cap of the described pump housing, be provided with seal ring I, so the utility model has avoided original employing pin to be fixed retainer and coil component spring, and pin is in use easily loosening, thus the phenomenon of impact sealing, the utility model is located at volute spring fixed cover on major axis, and in major axis rotary course, volute spring revolves tighter and tighter, thereby stably to rotating ring, provide thrust, realize well sealing function, can effectively avoid leaking, make sealing more reliable, also make sealing configuration simpler.
Due to described seal ring I and described seal ring II by ethylene-propylene-diene monomer glue-line as body, at described the external polytetrafluoroethylene floor that is coated with, so, the utility model is by applying polytetrafluoroethylene floor at ethylene-propylene-diene monomer glue-line seal ring skin, ethylene-propylene-diene monomer glue-line has good elasticity, and polytetrafluoroethylene floor has extremely strong anticorrosive property, as the erosion of benzene etc., thereby make the sealability of seal ring better, can adapt to more severe working environment.
Accompanying drawing explanation
Fig. 1 is easy structure schematic diagram of the present utility model;
Fig. 2 is the simple and easy sectional view of described sealing seat.
Embodiment
As depicted in figs. 1 and 2, the utility model comprises motor 1 and the pump housing, in the described pump housing, be provided with a major axis 2, one end of described major axis 2 is connected by coupling with the output shaft of described motor 1, on one end that the output shaft with described motor 1 of described major axis 2 is connected, be arranged with sealing seat 3, described sealing seat 3 comprises the throw-out collar 31 setting gradually, rotating ring 32, stationary ring 33 and be set on described major axis 2 and be positioned at the spring 34 of described throw-out collar 31 front ends, described spring 34 is volute spring, described volute spring fixed cover is located on described major axis 2, between described throw-out collar 31 and described rotating ring 32, between described stationary ring 33 and the end cap of the described pump housing, be provided with seal ring I 35.
The described pump housing comprises cylinder body 4, is arranged on driving wheel 5, the follower 6 with described driving wheel 5 engagements, the first end cap 7, the second end cap 8 in described cylinder body 4 and the minor axis 9 that passes described follower 6, described major axis 2, through described driving wheel 5, is provided with seal ring II 10 between described the first end cap 7, described the second end cap 8 and described cylinder body 4.
Described seal ring I 35 and described seal ring II 10 by ethylene-propylene-diene monomer glue-line as body, at described the external polytetrafluoroethylene floor that is coated with.
The utility model is by changing the sealing configuration at the major axis place in the pump housing, change the mode of former cause pin location, directly utilized that volute spring is sheathed to be fixed on major axis, thereby made sealing pair more reliable, having prevented the generation of leaking, is the better gear pump mechanism of a kind of sealability.This mechanism, for comparatively severe working environment, still can guarantee the reliability of sealing.
The utility model can be applicable to pumping unit field.
