Description
[technical field]
The present invention relates to the manufacturing field of metal track, specifically a kind of sealing element guard ring of metal track.
[background technology]
Along with improving constantly of industrial automatization, the application of excavating machine more and more widely.But in many enterprises of China, the service life of the used metal track of excavating machine is also lower at present.The crawler belt life-span is low, the working portion precision stability is poor, not only can influence quality, and can cause the huge waste of costs such as material, machining period, increases cost greatly and reduces production efficiency, has a strong impact on competitiveness of product.
There are some researches show: the service life of metal track is improper with heat treatment, selection is improper, unreasonable, lubricious bad, the design level difference of unreasonable structure, mechanical processing technique etc. is all multifactor relevant.According to having decreased in a large number the analytic statistics of crawler belt, in causing the various factors that crawler belt damages, heat treatment is improper to account for 35%, and selection is improper, technological problems accounts for 20%, and factors such as lubricious sealing problem, plant issue, unreasonable structure account for 45%.Therefore, in metal track design and manufacturing process, select appropriate material for use, the appropriate design structure, select rational heat treatment technology, the machining process route of each part of appropriate arrangements crawler belt, improving working conditions all helps improving the quality and the service life of crawler belt.
[summary of the invention]
The sealing element guard ring of metal track of the present invention is to design a kind of parts that are used to protect sealing member at factors such as lubrication and seal problem, plant issue, unreasonable structure.
For solving the problems of the technologies described above, the sealing element guard ring of a kind of metal track of the present invention is characterized in that sealing element guard ring is the circular metal ring, and sealing element guard ring is enclosed within outside the sealing member; The pars intermedia of bearing pin is with sleeve pipe, and casing inner diameter is greater than the external diameter of bearing pin, both free-running fits; Respectively be with interior outer link outside bearing pin and the sleeve pipe two ends, a end of outer link is enclosed within the two ends up and down of bearing pin, and the b end of inner link is enclosed within sleeve pipe two ends up and down, and a end of outer link joins with the b end of inner link, and a space is arranged between the two; Sealing member and sealing element guard ring place in the cavity of being made up of the b end and the bearing pin of a of outer link end, inner link, and the rounded seal protection ring is enclosed within outside the sealing member; The width of sealing element guard ring is greater than the width of sealing member, in the counterbore that b holds and sleeve pipe constitutes of an end of sealing element guard ring insertion by inner links.
The development of metal track mainly has benefited from it and should have good working performance and durability, reliability with using, and only in this way could greatly improve the work efficiency and the economic benefit of crawler belt.And good lubrication and seal system realizes one of method of above purpose just.The lubrication and seal systematic comparison is simple in the metal track of prior art, and sealing member directly is fitted between chain link and the sleeve pipe, and sealing member exposes to bearing pin and sleeve pipe.Lubricating oil is lubricated between chain link, sleeve pipe and bearing pin three, and sealing member has just played the effect of sealing lubricating oil here.Because can there be the gap of 1-1.5mm up and down in chain link and chain link between the sheet when press-fiting.Because excavating machine generally is operation under harsh and unforgiving environments such as earth, grit; operating environment is more abominable; the sealing system of the general metal track that uses is without any under the system protection; earth, grit are easy to enter in this gap; make sealing system suffer the corrosion and the wearing and tearing of rock grit, to such an extent as to decrease broken.This not only makes sealing member lose the leak free effect, and the cost of the damage of sealing member system in maintenance is also higher, and lubricating oil leaks and also causes cost to increase simultaneously.
The present invention is with sealing element guard ring in the outside of sealing member; sealing element guard ring just in time between sealing member, chain link and sleeve pipe three, belongs to free-running fit, neither influences the rotation of chain link and sleeve pipe; protected sealing member again, sealing element guard ring can make that also lubricating oil does not leak outside.Good sealing system not only can reduce financial cost, and helps improving the quality and service life.
The metal track that the sealing element guard ring of metal track of the present invention is housed is compared with the metal track of prior art, remedies the shortcoming of prior art on sealing system.The device that increases a protection sealing member on the sealing member of metal track has further solved sealing member occurring wear problem in use, makes oil sealing be protected, and can increase oil sealing normal service life.To solve the problem that causes crawler belt to damage to owing to lubrication and seal factor, unreasonable structure factor,, can solve many owing to sealing member damages many dysgenic problems that causes though this device is simple in structure.
