Abstract
The utility model discloses a combined sealing end lid which is composed of an outer end lid and an inner end lid. Sealing grooves are processed on the inner holes of the outer end lid and the inner end lid; a sealing material and a regulating slice are arranged in the inner holes corresponding to the sealing grooves; the inner and the outer end lids are fixed by a bolt. The combined sealing end lid overcomes the defects that an existing end lid can not press the sealing material which needs to be installed beforehand; the sealing material and a shaft are made to be combined tightly through pressing the both ends of the two end lids to achieve no leakage. The utility model has the advantages of simple structure, convenient maintenance, low cost, and good sealing effect.
Description
The utility model relates to a kind of sealing arrangement, particularly a kind of combination sealing end cap.
Various for a long time combustion engines, turbo-machine, automotive gas turbine, electrical motor, electrical generator, reductor, variable-speed motor, oil pump, water pump and Oil, Water, Gas seal case leak serious, cause the oil plant waste, contaminated environment has been aggravated the wearing and tearing of parts sometimes because of oil starvation, increased service expenditure.Its reason is that hermetically-sealed construction is unreasonable, and existing end cap all is a single-piece, is processed with seal groove at the internal diameter of end cap, and built-in leakproofing material is inserted in the diameter of axle again, fastening end cap.Because the leakproofing material and the diameter of axle are not easy coupling, be easy to generate leakage like this.Chinese patent cn2093271 has introduced a kind of anti-leak housing, is processing groove on the end cap cylindrical of housing or in conjunction with the plane, and rubber strip is packed in the groove, compresses then.Can increase certain leakage prevention capability although it is so, but the matching problem of its former leakproofing material that pre-exists and the diameter of axle does not solve.
The purpose of this utility model provides a kind of combination sealing end cap that can make the leakproofing material and the diameter of axle mate and combine closely.
The purpose of this utility model can reach by the following technical programs: the utility model combination sealing end cap is made up of outer end cap and inner end cap, endoporus in outer end cap and inner end cap processes seal groove, built-in and the corresponding leakproofing material of seal groove and levelling sheet, be processed with screw on outer end cap, the inner end cap, utilize bolt that interior outer end cap is fastening.
The beneficial effects of the utility model are: because end cap is divided into two, seal groove respectively accounts for half at interior outer end cap, and the coupling of the leakproofing material and the diameter of axle will be carried out easily with adjustment, keep in repair also very convenient.By bolt interior outer end cap fastening the time, is also pushed leakproofing material in addition, the leakproofing material and the diameter of axle are combined closely, reach no leak.The utility model is simple in structure, and is easy to maintenance and expense is few, and good sealing effect is used very extensive.
