Description
Technical Field
The utility model belongs to the hydroelectric generating set field of overhauing indicates a bearing dust keeper especially.
Background
A staff usually carries out A/B/C class maintenance on the hydroelectric generating set after the hydroelectric generating set operates for a period of time according to the operating state of the hydroelectric generating set. In the process of maintenance, the bearing is disassembled and maintained according to needs, and in the process of maintenance, the bearing bush, the automatic element and the like need to be installed or debugged.
At present, in the bearing maintenance process, a bearing cover cannot be installed back to be sealed every time due to large weight and structure, and the bearing cover is generally sealed by white cloth or plastic cloth.
However, the use of white cloth or plastic cloth to fix around the main shaft can make the bearing not completely cover, because the bearing is circular, and the diameter is greater than the width of the white cloth or plastic cloth, partial position can not be covered, and the cover is not strong enough, easy to be damaged, cause the foreign matter to enter the bearing, can not reach the purpose of sealing cover protection.
If the original bearing cover is used for protection, the bearing cover needs to be decomposed and dismantled each time the bearing cover works, so that the work is repeated, a large amount of manpower and working time are wasted, and the efficiency is low; in a lower guide area, due to the narrow space, the bearing cover is difficult to remove, and the normal work is also influenced.
SUMMERY OF THE UTILITY MODEL
In the prior art, the problem that needs to be solved to realize bearing dustproof has: the bearing dust cover has enough strength, is light and convenient, and has excellent protection and sealing effects; the bearing dust cover has low cost and is convenient to popularize and apply; the bearing dust cover is simple in structure and easy to install and detach.
To the above problem, the utility model provides a bearing dust keeper, include: the bearing dust cover comprises a plurality of bearing dust covers, wherein one end of each bearing dust cover is provided with a nylon thread gluing which is adhered to a main shaft of the unit, the other end of each bearing dust cover is provided with a magnetic buckle which is adhered to the outside of the bearing, and every two bearing dust covers are adhered through the nylon thread gluing; when overhauing the unit, utilize bearing dust keeper to carry out dustproof protection to the bearing of unit, if overhaul a certain part of bearing, overhaul through opening corresponding one or polylith bearing dust cover.
Further, the bearing dust-proof device comprises six bearing dust-proof covers.
Further, the bearing dust cover is made of a tarpaulin.
The utility model discloses a bearing dust keeper can solve the dustproof problem of bearing when the unit overhauls effectively, improves the efficiency of maintenance work.
Drawings
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the principles of the invention. In the drawings:
fig. 1 is a schematic top view of a bearing dust-proof device according to an embodiment of the present invention.
Fig. 2 is a schematic view of a part of a bearing dustproof apparatus according to an embodiment of the present invention.
Detailed Description
The following description of the preferred embodiments of the present invention will be made in conjunction with the drawings and the accompanying drawings to further illustrate the technical means adopted to achieve the objects of the present invention.
As shown in fig. 1 and 2, the bearing dust-proof device includes: a plurality of bearing dust covers 1; wherein,
one end of each bearing dust cover 1 is provided with a nylon thread gluing 2 which is adhered on a main shaft 3 of the unit, has certain flexibility and is used for fixing the inner ring of the bearing dust cover 1;
the other end of each bearing dust cover 1 is provided with a magnetic buckle 4 which is adsorbed outside the bearing 5 (namely outside the bearing groove) and used for fixing the outer ring of the bearing dust cover 1;
every two bearing dust covers 1 are bonded through nylon thread gluing 2; when overhauing the unit, utilize bearing dust keeper to carry out dustproof protection to the bearing 5 of unit, if overhaul a certain part of bearing 5, the accessible is opened and is overhauld with the corresponding one or polylith bearing dust cover 1 of a certain part of overhauing.
In a specific embodiment, as shown in fig. 1, the bearing dust-proof device comprises six pieces of bearing dust-proof covers 1.
In practical application, the size (or known size) of the bearing can be measured before the unit is overhauled, a set of bearing dustproof device is manufactured according to the size of the bearing, wherein the bearing dustproof cover is made of waterproof canvas, and device optimization can be carried out according to practical conditions under the shutdown state of the unit on site.
The utility model discloses a bearing dust keeper can solve the dustproof problem of bearing when the unit overhauls effectively, improves the efficiency of maintenance work.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
Claims (3)
