Description
Technical Field
The utility model relates to a centrifugal fan accessory field, in particular to sealed effectual a bearing frame end cover for centrifugal fan.
Background
The bearing frame is that many mechanical equipment are used for fixedly, support and supply the rotatory part of pivot commonly used, and centrifugal fan is in order to solve the lubricated problem of bearing, generally all installs the bearing frame end cover on the bearing frame, plays the effect of location, dustproof and protection, but current bearing frame end cover when using, because the sealed effect of end cover is relatively poor, leads to the lubricating oil in the bearing frame to leak, influences the life of bearing frame.
Therefore, a new bearing seat end cover with good sealing effect for the centrifugal fan is needed to be provided.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a sealed effectual bearing frame end cover for centrifugal fan can improve sealed effect, reduces the leakage of lubricating oil in the bearing frame.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a sealed effectual bearing frame end cover for centrifugal fan, its includes the main part, evenly distributed is in a plurality of bolt holes of main part periphery, setting are in dead eye, evenly distributed in the main part a plurality of oil return holes of dead eye periphery, setting are in barrier ring, setting in the main part are in first sealing ring and second sealing ring in the main part.
Specifically, a filter screen is arranged on the oil return hole.
Specifically, the number of the bolt holes is equal to the number of the oil return holes, and the oil return holes correspond to the bolt holes.
Specifically, the blocking rings are distributed in the main body in sequence.
Specifically, the stop ring is communicated with the oil return hole.
Specifically, the first sealing ring and the second sealing ring are made of rubber.
The utility model relates to a sealed effectual bearing frame end cover for centrifugal fan's beneficial effect is, through first sealing washer and the cooperation of second sealing washer, can effectually prevent that the lubricating oil in the bearing frame from leaking from the gap between bearing frame end cover and the bearing frame, has improved sealed effect, in addition, through the cooperation of barrier ring and oil gallery, can stop and guide the backward flow to the bearing frame in owing to the bearing rotates and the lubricating oil of being taken out, reduces the leakage volume of lubricating oil in the bearing frame.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-3, a bearing seat end cover for a centrifugal fan with good sealing effect comprises a main body 1, a plurality of bolt holes 3 uniformly distributed on the periphery of the main body 1, a bearing hole 2 arranged on the main body 1, a plurality of oil return holes 4 uniformly distributed on the periphery of the bearing hole 2, a stop ring 6 arranged in the main body 1, and a first sealing ring 7 and a second sealing ring 8 arranged on the main body 1.
Specifically, a filter screen 5 is arranged on the oil return hole 4. Filter screen 5 can filter the lubricating oil that flows back to in the bearing frame from oil gallery 4, prevents that external dust from getting into the bearing frame, reduces the wear rate of bearing frame, prolongs the life of bearing frame.
Specifically, the number of the bolt holes 3 is equal to the number of the oil return holes 4, and the oil return holes 4 correspond to the bolt holes 3. The oil return holes 4 correspond to the bolt holes 3, so that workers can install the bearing seat end cover to the bearing seat without adjusting the bearing seat end cover to enable the oil return holes 4 to be located at the lowest part, the bearing seat is convenient to assemble by the workers, and the assembling efficiency is improved.
Specifically, the blocking rings 6 are distributed in the main body 1 in sequence. The plurality of blocking rings 6 can block and collect the lubricating oil on the bearing for a plurality of times, thereby further reducing the leakage amount of the lubricating oil.
Specifically, the stop ring 6 is communicated with the oil return hole 4.
Specifically, the material for manufacturing the first seal ring 7 and the material for manufacturing the second seal ring 8 are both rubber. The deformability of rubber is better, and when the bearing frame was assembled with the bearing frame end cover, first sealing ring 7 and second sealing ring 8 received extrusion deformation for form twice between bearing frame and the bearing frame end cover and block, thereby reduce the leakage of lubricating oil, improve sealed effect.
This sealed effectual theory of operation that is used for centrifugal fan's bearing frame end cover: main part 1 is fixed with the bearing frame through bolt hole 3, and first sealing ring 7 and second sealing ring 8 seal the gap between main part 1 and the bearing frame twice, improve sealed effect, and the bearing passes main part 1 through dead eye 2, and when the bearing rotated, stop ring 6 can stop remaining lubricating oil on the bearing and guide to oil gallery 4 in, lubricating oil passes through oil gallery 4 and flows back to in the bearing frame to reduce the outer volume of leaking of lubricating oil, improve sealed effect.
Compared with the prior art, this sealed effectual a bearing frame end cover for centrifugal fan, through first sealing washer and the cooperation of second sealing washer, can effectually prevent that the lubricating oil in the bearing frame from leaking from the gap between bearing frame end cover and the bearing frame, improved sealed effect, in addition, through the cooperation of barrier ring 6 and oil gallery 4, can stop and guide the backward flow to the bearing frame in owing to the bearing rotates and the lubricating oil of being taken out, reduce the leakage volume of lubricating oil in the bearing frame.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
