The utility model in order to solve the problem, thus provides the double suction pump shaft seal parts that a kind of uniform force, difficulty of processing are low, maintenance cost is low.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of double suction pump shaft seal parts, described shaft seal parts comprise clutch shaft bearing body and the second bearing support, described clutch shaft bearing body and the second bearing support are symmetrical arranged, described clutch shaft bearing body is positioned on tail end bearing part, described second bearing support is positioned on drive end bearing parts, described clutch shaft bearing body one end coordinates with the pump housing and pump cover seam, the other end is connected with end cap, described second bearing support one end coordinates with the pump housing and pump cover seam, the other end is connected with bearing gland, and described clutch shaft bearing body and the second bearing support are respectively equipped with oil drainage hole.
In a preferred embodiment of the present utility model, described clutch shaft bearing body and the second bearing support are made up of the spring bearing of two symmetrical smaller part round shape respectively.
In a preferred embodiment of the present utility model, described clutch shaft bearing body and be all respectively equipped with outside framework oil seal between the second bearing support and pump shaft.
In a preferred embodiment of the present utility model, described clutch shaft bearing body and be all respectively equipped with water retaining ring assembly between the second bearing support and pump shaft.
By technique scheme, the beneficial effects of the utility model are:
The utility model good positioning effect, uniform force, not easily produce vibration, improve the working life of bearing and reduce maintenance cost.
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 be existing shaft seal parts with tail end bearing part coordinate schematic diagram;
Fig. 2 be existing shaft seal parts with drive end bearing parts coordinate schematic diagram;
Fig. 3 be clutch shaft bearing body with tail end bearing part coordinate schematic diagram;
Fig. 4 be the second bearing support with tail end bearing part coordinate schematic diagram.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 3 and Fig. 4, a kind of double suction pump shaft seal parts that the utility model provides, it comprises clutch shaft bearing body 200 and the second bearing support 300.
Clutch shaft bearing body 200 and the second bearing support 300 are symmetricly set on the left and right sides of the pump housing 400 respectively, and clutch shaft bearing body 200 is positioned on tail end bearing part, and the second bearing support 300 is positioned on drive end bearing parts.
Clutch shaft bearing body 200 and the second bearing support 300 are made up of the spring bearing of two symmetrical smaller part round shape respectively;
One end of clutch shaft bearing body 200 coordinates with the pump housing 400 and pump cover 410 seam, and the other end is supported on the bearing gland 430 of end cap 420, and such clutch shaft bearing body 200 is just supported between the pump housing 400 and tail end bearing 600.
Because clutch shaft bearing body 200 coordinates with the pump housing 400 and pump cover 410 seam, and connected by bolt 500, which enhance locating effect, and clutch shaft bearing body 200 is made up of the spring bearing of two symmetrical smaller part round shape, such uniform force, not easily shakes.
Between clutch shaft bearing body 200 and tail end bearing 600, be also provided with bearing gasket 610, prevent clutch shaft bearing body 200 from damaging tail end bearing 600 by pressure like this.
Clutch shaft bearing body 200 is also provided with oil drainage hole 210, is convenient to the waste oil in tail end bearing 600 to discharge like this.
In addition, between clutch shaft bearing body 200 and pump shaft 440, be also provided with outside framework oil seal 450, replace existing felt circle by outside framework oil seal 450, substantially increase sealing.
Moreover, between clutch shaft bearing body 200 and pump shaft 440, be also provided with water retaining ring assembly 460, can further improve sealing.
Second bearing support 300, its one end coordinates with the pump housing 400 and pump cover 410 seam, and the other end is supported on the bearing gland 710 of driving bearing 700, and such second bearing support 300 is just supported between the pump housing 400 and driving bearing 700.
Because the second bearing support 300 coordinates with the pump housing 400 and pump cover 410 seam, and connected by bolt 510, which enhance locating effect, and the second bearing support 300 is made up of the spring bearing of two symmetrical smaller part round shape, such uniform force, not easily shakes.
Second bearing support 300 is also provided with oil drainage hole 310, is convenient to the waste oil in driving bearing 700 to discharge like this.
In addition, between the second bearing support 300 and pump shaft 440, be also provided with outside framework oil seal 720, replace existing felt circle by outside framework oil seal 720, substantially increase sealing.
Moreover, between the second bearing support 300 and pump shaft 440, be also provided with water retaining ring assembly 730, can further improve sealing.
Like this, because clutch shaft bearing body 200 and the second bearing support 300 lay respectively between the pump housing 400 and tail end bearing 600 and between the pump housing 400 and driving bearing 700, do not need to arrange at the pump housing 400 two ends and protrude semicircle positioning supports parts, this reduces the axial length of pump shaft 440, thus reduce difficulty of processing, improve machining accuracy.
In addition, because the utility model have changed sealed member, improve sealing, thus reduce the possibility of bearing water inlet, improve the working life of bearing.
Moreover the utility model eliminates seal, seal chamber part and bearing bore body are divided and merges into a single whole, reduce managed inventory cost.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
