Abstract
The utility model discloses a kind of thin oil lubricant nitrogen-sealed bearing support, it is characterized in that, comprise aluminum seal, deep groove ball bearing and bearing support, described aluminum seal internal installation shaft bearing, described bearing support inside is provided with deep groove ball bearing, described bearing support inwall is provided with skewed dentate stripe, runs through described bearing support and aluminum seal is provided with nitrogen inlet hole.The utility model nitrogen enters the seal clearance between dentate stripe and deep groove ball bearing by inlet hole, nitrogen air film is formed between seal clearance, pressure, higher than the pressure of internal gas, makes gas from the clearance leakage between sealing and axle, can not reach the effect of sealing.
Description
Technical field
The utility model relates to a kind of thin oil lubricant nitrogen-sealed bearing support.
Background technique
Multistage centrifugal blower is widely used in environmental protection industry (epi), and lubrication and the sealing of this kind of blower generally adopt sliding bearing and mechanical seal, and bearing block structure is more complicated, and take up room large, thoroughly can not stop gas leakage, seal arrangement is complicated.But the blower of small flow can adopt the simpler roller bearings of structure and nitrogen-sealed, without the need to petrol station and complicated seal arrangement, and save space.
Model utility content
To achieve these goals, the utility model proposes a kind of thin oil lubricant nitrogen-sealed bearing support, solve conventional multi-level centrifugal blower bearing support seal structure complex, the problem such as take up room large, wherein eliminate petrol station and complicated sealing configuration, reduce cost, improve benefit.
The technical solution of the utility model is achieved in that
A kind of thin oil lubricant nitrogen-sealed bearing support, comprise aluminum seal, deep groove ball bearing and bearing support, described aluminum seal internal installation shaft bearing, described bearing support inside is provided with deep groove ball bearing, described bearing support inwall is provided with skewed dentate stripe, runs through described bearing support and aluminum seal is provided with nitrogen inlet hole.
Further, described dentate stripe is at least 1, and arranges at equal intervals.
Further, nitrogen inlet hole is communicated to the bearing support inside at place, dentate stripe position.
The beneficial effect that the utility model produces is: the utility model nitrogen enters the seal clearance between dentate stripe and deep groove ball bearing by inlet hole, nitrogen air film is formed between seal clearance, pressure is higher than the pressure of internal gas, make gas from the clearance leakage between sealing and axle, the effect of sealing can not be reached.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of thin oil lubricant nitrogen-sealed bearing support, comprise aluminum seal 1, deep groove ball bearing 5 and bearing support 2, described aluminum seal 1 internal installation shaft bearing 2, described bearing support 2 inside is provided with deep groove ball bearing 5, described bearing support 2 inwall is provided with skewed dentate stripe 3, runs through described bearing support 2 and aluminum seal 1 is provided with nitrogen inlet hole 4.In this structure, dentate stripe 3 is at least 1, and arranges at equal intervals, and the bearing support that nitrogen inlet hole 4 is communicated to place, dentate stripe position is inner.
The utility model in actual use, main shaft is arranged on deep groove ball bearing 5, it is inner that lubricant oil is in aluminum seal 1, nitrogen is poured by nitrogen inlet hole 4, nitrogen enters into the seal clearance of dentate stripe 3 position, in bearing rotation process, skewed dentate stripe 3 rotates thereupon, nitrogen forms air film at seal clearance, and give the thrust on dentate stripe 3 true dip direction, namely the active force of air film is towards high pressure side, barrier gas drains to low pressure side by high pressure side, play sealing effect, bearing rotating speed is faster, and radiating effect is better.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (3)
