Abstract
The utility model proposes a kind of bearing dustproof device, comprise: polylith bearing dust-proof cover, wherein, one end of each block bearing dust-proof cover is provided with nylon adherent buckle, be bonded on the main shaft of unit, the other end of each block bearing dust-proof cover is provided with magnetic clasp, is adsorbed in the Bearing outer of unit, is bonded between every two pieces of bearing dust-proof cover by nylon adherent buckle; When overhauling unit, utilizing bearing dustproof device to carry out proofing dust and protecting to the bearing of unit, if when overhauling certain part of bearing, overhauling by opening one or more bearing dust-proof cover corresponding.Bearing dustproof device of the present utility model, can solve the dust-proof problem of bearing during unit maintenance effectively, improves the efficiency of service work.
Description
Technical field
The utility model belongs to Hydropower Unit maintenance field, espespecially a kind of bearing dustproof device.
Background technique
Staff, usually after hydro-generating Unit runs a period of time, can carry out the maintenance of A/B/C level according to operating states of the units to it.In maintenance process, as required to bearing Disintegration overhaul, in bearing maintenance process, need to install or debugging efforts bearing shell, Automation Elements etc.
At present in bearing maintenance process, bearing cap all can not return more greatly because of weight and structure at every turn and put into row sealing, generally adopts calico or Polypropylence Sheet capping.
But utilize and adopt calico or Polypropylence Sheet bearing covering can be made incomplete around main shaft is fixing; because bearing is circular; and diameter is greater than the width of calico or Polypropylence Sheet; portion can not cover; and cover insufficient strength; easy breakage, causes foreign matter to enter bearing, does not reach the object of capping protection.
And if use former bearing cap to protect, when carrying out work at every turn, need to bearing cap carry out decomposition remove, cause work to repeat, waste a large amount of manpowers and operating time, inefficiency; Under lead region, due to narrow space, remove bearing cap difficulty, also can affect normal work.
Model utility content
In the prior art, realize the dust-proof problem solved that needs of bearing to have: bearing dust-proof cover should have enough intensity, and light, exclusion seal excellent effect; Bearing dust-proof cover with low cost, easy to utilize; Bearing dust cover structure is simple, is easy to installation and removal.
For the problems referred to above, the utility model proposes a kind of bearing dustproof device, comprise: polylith bearing dust-proof cover, wherein, one end of each block bearing dust-proof cover is provided with nylon adherent buckle, is bonded on the main shaft of unit, and the other end of each block bearing dust-proof cover is provided with magnetic clasp, be adsorbed in the outside of bearing, bonded by nylon adherent buckle between every two pieces of bearing dust-proof cover; When overhauling unit, utilizing bearing dustproof device to carry out proofing dust and protecting to the bearing of unit, if when overhauling certain part of bearing, overhauling by opening one or more bearing dust-proof cover corresponding.
Further, bearing dustproof device comprises six pieces of bearing dust-proof cover.
Further, bearing dust-proof cover is made up of Tarpauling.
Bearing dustproof device of the present utility model, can solve the dust-proof problem of bearing during unit maintenance effectively, improves the efficiency of service work.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms a application's part, does not form restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the plan structure schematic diagram of the bearing dustproof device of the utility model one embodiment.
Part-structure schematic diagram when Fig. 2 is the bearing dustproof device side-looking of the utility model one embodiment.
Embodiment
Below coordinating preferred embodiment graphic and of the present utility model, setting forth the technological means that the utility model is taked for reaching predetermined model utility object further.
Shown in composition graphs 1 and Fig. 2, this bearing dustproof device comprises: polylith bearing dust-proof cover 1; Wherein,
One end of each block bearing dust-proof cover 1 is provided with nylon adherent buckle 2, is bonded on the main shaft 3 of unit, has certain stretchability, and the inner ring for bearing dust-proof cover 1 is fixed;
The other end of each block bearing dust-proof cover 1 is provided with magnetic clasp 4, is adsorbed in the outside (that is, the outside of bearing groove) of bearing 5, fixes for the outer ring of bearing dust-proof cover 1;
Bonded by nylon adherent buckle 2 between every two pieces of bearing dust-proof cover 1; When overhauling unit, the bearing 5 of bearing dustproof device to unit is utilized to carry out proofing dust and protecting, if during certain part of maintenance bearing 5, overhauled with by one or more bearing dust-proof cover 1 of a certain partial response overhauled by opening.
In one embodiment, as shown in Figure 1, bearing dustproof device comprises six pieces of bearing dust-proof cover 1.
In actual applications, the size (or known dimensions) of bearing can be measured before unit maintenance, make a set of bearing dustproof device according to the size of bearing; wherein; bearing dust-proof cover is made up of Tarpauling, at the scene under compressor emergency shutdown state, can carry out installation optimization again according to actual conditions.
Bearing dustproof device of the present utility model, can solve the dust-proof problem of bearing during unit maintenance effectively, improves the efficiency of service work.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; and be not used in restriction protection domain of the present utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
