Abstract
The utility model relates to a novel sealing device for electric shovel lifting mechanisms, which is characterized in that the sealing device consists of a sealing oil shield, an oil return hole, an oil storage chamber, a supporting spring, sealing copper teeth and contact-type sealing rings. Two contact-type sealing rings are arranged in the sealing oil shield of a box body; the support spring is arranged between an inner ring and an outer ring of the two contact-type sealing rings; the oil storage chamber is arranged between the two contact-type sealing rings; an oil return position on the lower part of the oil storage chamber has the oil return hole; two circles of sealing copper teeth are arranged outside the contact-type sealing rings; a layer of felt is clamped between the sealing copper teeth; and the contact-type sealing rings are made from polymer composite materials which are lubricate the self, resist wear and can not damage shafts. Operation experiments prove that the novel sealing device for electric shovel lifting mechanisms thoroughly solves the phenomena of leaking and throwing oil under sealing, and improves the intact rate and operating rate of equipment.
Description
Technical field
The utility model relates to a kind of power shovel lifting gear new type sealing device.
Background technique
At present, power shovel is one of main extractive equipment of metallurgy industry iron ore, in the equipment that tradition is used, owing to the seal arrangement at lifting speed reducer three shaft ends is the fixed seal rings of twice, because be subjected to the restriction of structure, it is bonding with fracture again to cut a fracture Cheng Huanhou of place during installation.Adorn the sealing that fashion can guarantee a period of time just, fracture abutting edge generation cracking or seal ring spring failure can not replenish wearing clearance after operation a period of time, wearing and tearing that the Long contact time of cylinder and seal ring is mutual and leaking, because poor sealing performance, leakage of oil, cause the grease waste, befouling environment causes a hidden trouble for the equipment fireproofing.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, and purpose is to leak for improving seal arrangement, reduces the grease waste, improves the plant maintenance situation, eliminates hidden trouble of equipment, and a kind of power shovel lifting gear new type sealing device is provided.
The utility model power shovel lifting gear new type sealing device content Description:
The utility model power shovel lifting gear new type sealing device, it is characterized in that: be to constitute by sealed oil catch, spill port, accumulator, supported spring, sealed copper tooth, contact seal ring, twice contact seal ring is set in the sealed oil catch of casing, between the interior ring of twice contact seal ring and outer shroud, be provided with supported spring, in twice contact seal ring is accumulator, spill port is established in accumulator bottom oil return place, the outside of contact seal ring is provided with two seals copper tooth, and the centre of sealed copper tooth accompanies one deck felt.
The polymer composite that the contact seal ring adopts self-lubricating abrasion-resistant not hinder axle is made.
The utility model power shovel lifting gear new type sealing device proves through running experiment, has thoroughly solved the sealing leakage of oil, has got rid of oily phenomenon, has improved serviceability rate, the operating rate of equipment.
Description of drawings
Fig. 1 is a power shovel lifting gear new type sealing device structural representation
Among the figure: the 1st, casing, the 2nd, sealed oil catch, the 3rd, cylinder, the 4th, spill port, the 5th, accumulator, the 6th, supported spring, the 7th, sealed copper tooth, the 8th, contact seal ring.
Embodiment
The utility model power shovel lifting gear new type sealing device is achieved in that to do below in conjunction with accompanying drawing and specifies.See Fig. 1, the utility model power shovel lifting gear new type sealing device, be to constitute by: sealed oil catch 2, spill port 4, accumulator 5, supported spring 6, sealed copper tooth 7, contact seal ring 8, twice contact seal ring 8 is set in the sealed oil catch 2 of casing 1, between the interior ring of twice contact seal ring 8 and outer shroud, be provided with supported spring 6, supported spring 6 plays good gap compensating action, the no gap that can guarantee contact seal ring 8 and cylinder 3 contacts operation, can guarantee good sealing effect.The polymer composite that contact seal ring 8 adopts self-lubricating abrasion-resistant not hinder axle is made, and is accumulator 5 in twice contact seal ring 8, is used for gathering the lubricant oil that encircles seepage under the working state of power shovel when the operating mode out-of-flatness in first road.Establish spill port 4 in accumulator 5 bottom oil returns place, under the working state of ramp, can both make the oil catch proper functioning to guarantee power shovel.Be provided with two seals copper tooth 7 in the outside of contact seal ring 8, the centre of sealed copper tooth 7 accompanies one deck felt, prevents that outside dust from entering oil catch, the normal operation of ring and pollution oil in the influence.
Claims (2)
