Abstract
The utility model belongs to the technical field of rock drill equipment is sealed, especially, relate to a sealed spacer sleeve for rock drill swing drives cover, its characterized in that has two sealed spacer sleeves through the fix with screw respectively at the both ends of rock drill swing drives cover, and every sealed spacer sleeve inner edge and bearing inner race lean on together, follow outward with the distolateral chamfer department of rock drill swing drives cover aligns. The utility model discloses it increases sealed spacer sleeve to sheathe in at rock drill swing drives, but makes the continuous operation of rock drill swing drives cover reach 400 hours, can reach 800 hours even, and maintenance period gear box faying face oil -proof has prolonged swing drives cover life -time dilatation and more than 2 times, has practiced thrift the spare parts cost, makes rock drill pre -installation work load reduce, and post maintenance work volume reduces, is fit for extensively promoting in the same trade.
Description
Technical field
The utility model belongs to rock drill equipment technical field of sealing technology, especially relates to a kind of sealed spacer cover for rock drill revolution driving casing.
Background technique
Rock drill is produced in perforation process at iron ore, because rock drill is at high load, and thump and operation under vibrating large state, rate of fault is relatively high:
(1) rock drill design relative complex, assembling maintenance is more difficult, and repair rate is high;
Rock drill forms by impacting, cushioning and turn round three parts.Its major failure is exactly leakage of oil.Its front end, the leakage of oil at any position, rear end all need decompose dismounting between service work, has ressembled.Hydraulic oil is revealed general inspection and is changed the component that may wear to limit, changes corresponding seal element etc.But sometimes, the rock drill continuous operation of ressembling leakage of oil once more in tens hours, after dismounting component, seal element, without apparent damage, seems very thorny.When long-term maintenance rock drill finds to let out in hydraulic oil and reaches a certain amount of, enter the sealing station of butter envelope along the spatial position of rotary motor oil transmission shaft, thus enter gear-box, mix with the yellow drier oil of its inside, in gear-box front/rear end generation leakage of oil.Even if when hydraulic oil mixes with yellow drier oil the service time reaching regulation, gear-box butter envelope is not damaged yet, but function is lost, butter seals the sealing position combined with rotary drive shaft cover and weares and teares, when forming groove mark (phenomenon that so-called buffing is hard) maintaining, even if replacing grease seal, wear phenomenon also can aggravate, do not have grease proofing effect, once certain position hydraulic oil again leaks and will invade gear-box, cause groove mark more and more heavier (general 2 service cycles, continuous operation 800 hours) now to turn round driving casing to be just done for;
(2) imported components is expensive, and cost pressure is large, and part relative shortage, changes not in time, is also one of reason that repair rate is high;
(3) driving casing unit price is turned round expensive;
(4) rock drill prepackage workload is large, and post maintenance workload increases.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, and the sealed spacer cover for rock drill revolution driving casing easy to use, increases the working life of rock drill revolution driving casing, reduce oil leakage phenomenon, reduce maintenance workload, reduce the spare parts cost in mine.
The purpose of this utility model is realized by following technical proposals:
Sealed spacer cover for rock drill revolution driving casing of the present utility model, it is characterized in that being fixed with two sealed spacer covers at the two ends of rock drill revolution driving casing respectively by screw, edge and bearing inner race snap in each sealed spacer cover, align in the chamfering place that outer and described rock drill turn round driving casing side.
Anaerobic adhesive is scribbled between described rock drill revolution driving casing and sealed spacer cover.
Advantage of the present utility model:
The utility model by increasing sealed spacer cover on rock drill revolution driving casing, make rock drill turn round driving casing and continuous operation can reach 400 hours, even can reach 800 hours, maintenance period gear-box junction plane is oil-proof, extend revolution driving casing life more than 2 times, save spare parts cost, make rock drill pre-install workload and reduce, post maintenance workload reduces, and is adapted at extensively promoting in the same industry.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, sealed spacer cover for rock drill revolution driving casing of the present utility model, it is characterized in that being fixed with two sealed spacer covers 1 at the two ends of rock drill revolution driving casing respectively by screw 2, each sealed spacer overlaps 1 li of edge and bearing inner race snap, aligns in the chamfering place that outer and described rock drill turn round driving casing side.
Anaerobic adhesive is scribbled between described rock drill revolution driving casing and sealed spacer cover 1.
The utility model increases sealed spacer cover 1 on rock drill revolution driving casing, and installation process is as follows:
(1) because sealed spacer cover 1 is outer processing spare part, first check with hermaphrodite caliper and vernier calliper whether the endoporus of the sealed spacer cover 1 of both sides meets standard (transition fit allows a small amount of gap) with coordinating of former revolution driving casing;
(2) with auxiliary mold indentation sealing spacer sleeve 1, making it inner edge and bearing inner race snap, aligns with the chamfering place of the both sides of driving casing in outer.Need before press-in to smear a small amount of anaerobic adhesive, Here it is add the wearing and tearing of sealing station after be easy to the sealed spacer cover 1 changed and kept former revolution driving casing, be equivalent to the lining of individual belt wear many.After every two service cycles, just must change it, keep this expensive items of former revolution driving casing;
(3) after passed examination, be screwed into the screw 2 of location, both sides, screw 2 does not spill its sealed spacer cover surface.
Again after 24 hours, carry out the parts assembling of speed reducer.
The utility model by increasing sealed spacer cover 1 on rock drill revolution driving casing, make rock drill turn round driving casing and continuous operation can reach 400 hours, even can reach 800 hours, maintenance period gear-box junction plane is oil-proof, extend revolution driving casing life more than 2 times, save spare parts cost, make rock drill pre-install workload and reduce, post maintenance workload reduces, and is adapted at extensively promoting in the same industry.
Claims (2)
1. the sealed spacer cover for rock drill revolution driving casing, it is characterized in that being fixed with two sealed spacer covers at the two ends of rock drill revolution driving casing respectively by screw, edge and bearing inner race snap in each sealed spacer cover, align in the chamfering place that outer and described rock drill turn round driving casing side.
2. the sealed spacer cover for rock drill revolution driving casing according to claim 1, is characterized in that scribbling anaerobic adhesive between described rock drill revolution driving casing and sealed spacer cover.
