Abstract
The utility model relates to a quick internal and external assembled/disassembled bearing sealed device, which comprises a bearing base, a bearing, a bearing cover and a fixed bearing cover which are positioned at the inside and outside of the concrete mixer, a principal bearing and a bearing sealed device which are arranged in the concrete mixer, and a butter pipe which is arranged at the bearing sealed device. The bearing sealed device consists of a sealed cover arranged at the principal bearing and assumes two semicircles shape, more than two sealed patches which are chucked at the outer bevel of the sealed cover, two sealed patch pressed boards which are separately chucked at the two sealed patches therein and displays with two semicircles, a sealed fixed cover with a butter way which is positioned between the more than two sealed patches, and a sealed board fixed bolt which arranged to through the two sealed patches pressed board, the more than two sealed patches, the sealed fixed cover and the bearing base and make them fixed with each other. The fixed bearing cover which is arranged at the principal bearing displays with two semicircles. Using the utility model can prolong the service life of the concrete mixer device, and reduce the maintenance cost, due to a part of the units are made up of two semicircles, the utility can be removed and installed quickly.
Description
Technical field
The utility model relates to the concrete mixer that construction industry is used, the fast inside and outside reassembling type shaft sealer in particularly a kind of concrete mixer.
Background technique
The concrete mixer that is used for construction industry for a long time after use a period of time, spillage can occur at the main shaft two ends, if untimely replacing shaft sealer, will cause bearing, bearing support, main shaft to damage, can bring adverse consequences, also can influence concrete production equipment operation.If keep in repair, then must change labyrinth-type excluder, must pull down hinge wheel, bearing support or gear-box, coupling earlier, change seal arrangement then.The dismounting maintenance very bothers like this, and maintenance difficulty is big again, and every replacing once needs 24 hours, needs a couple of days sometimes, and its replacing speed is slow, and maintenance cost is higher.
Summary of the invention
Task of the present utility model provides a kind of improved fast inside and outside reassembling type shaft sealer, and it has solved the problem that existing shaft sealer dismounting maintenance bothers, replacing speed is slow, maintenance cost is high.
The technical solution of the utility model is as follows:
A kind of fast inside and outside reassembling type shaft sealer, it comprises bearing support and the bearing that is positioned at the concrete mixer inboard and the outside, axle sleeve and fixed axle sleeve, be placed in main shaft wherein, shaft sealer, and be placed in butter pipe on the shaft sealer, described shaft sealer comprises that one is installed in two the semicircular stuffing box glands that are on the main shaft, be clamped in the diaphragm seal on the outer inclined-plane of stuffing box gland more than two, two be pressed on wherein two diaphragm seal outsides respectively respectively be two semicircular diaphragm seal pressing plates, one the sealing and fixing cover that has the butter oil duct between two above diaphragm seals, and be placed through two diaphragm seal pressing plates, two above diaphragm seals, between sealing and fixing cover and the bearing support and make the sealing plate fixing bolt that they are fixed together; The described fixed axle sleeve that is installed on the main shaft is two semicircles.
Adopt fast inside and outside reassembling type shaft sealer of the present utility model, can prolong the working life of concrete mixer equipment, accelerate maintenance speed, reduce maintenance cost, satisfy users' usage requirement.
Description of drawings
Fig. 1 is a kind of structural representation that the fast inside and outside reassembling type shaft sealer of two diaphragm seals is housed of the present utility model.
Fig. 2 is a kind of structural representation that the fast inside and outside reassembling type shaft sealer of three diaphragm seals is housed of the present utility model.
Embodiment
Referring to Fig. 1 and Fig. 2, fast inside and outside reassembling type shaft sealer of the present utility model comprises bearing support 1,11 and the bearing 2 that is positioned at the concrete mixer inboard and the outside, axle sleeve 3,31 and fixed axle sleeve 4, be placed in main shaft 5 wherein, shaft sealer, and be placed in butter pipe 6 on the shaft sealer.Inner shafts bearing 11 is connected on the concrete mixer by fixing bolt 12.
Shaft sealer is equipped with stuffing box gland 7, diaphragm seal 8, diaphragm seal pressing plate 9, sealing and fixing cover 10 and sealing plate fixing bolt 13.Stuffing box gland 7 is two semicircles, is installed on the main shaft 5.Diaphragm seal 8 has two (as shown in Figure 1) or three (as shown in Figure 2).Diaphragm seal 8 is the fracture shape, is clamped in respectively on the outer inclined-plane of stuffing box gland 7.Diaphragm seal 8 is located by locating stud at incision position, with the glue gummed, is convenient to dismounting again.Diaphragm seal pressing plate 9 has two, respectively is two semicircles, is pressed on the outside of the diaphragm seal 8 that is positioned at two ends respectively.Sealing and fixing cover 10 has butter oil duct 101, and it is installed between sealed at both ends 8.Diaphragm seal in centre 8 among Fig. 2 in three diaphragm seals 8 is installed together with sealing and fixing cover 10.Sealing and fixing cover 10 can be made up of two semicircular bodies, also can be made into an integral body.One sealing plate fixing bolt 13 is set between two diaphragm seal pressing plates 9, two above diaphragm seals 8, sealing and fixing cover 10 and the bearing supports 11 and they is fixed together.
The fixed axle sleeve 4 that is installed on the main shaft 5 is two semicircles.In order to improve the working life of part, stuffing box gland 7 and diaphragm seal pressing plate 9 are made by high molecular abrasion-proof material or wear-resistant metal material, and diaphragm seal 8 is made by wear-resisting, oil resistant rubber or polyurethane.
Working procedure of the present utility model is as follows:
Stuffing box gland 7 is with main shaft 5 rotation that closely cooperates, two or three diaphragm seals 8 contact with the outer inclined-plane of stuffing box gland 7 tightly, butter enters sealing and fixing from butter pipe 6 and overlaps 10 oil ducts 101 under oil pump work, enter the oil seal chamber again, and form certain oil pressure, prevent that in the mode of oily water proof pulp-water from from inside outwards flowing.
After concrete mixer is installed fast inside and outside reassembling type shaft sealer of the present utility model, when needing maintenance as if spillage occurring at the main shaft two ends, just need not pull down hinge wheel and bearing support, just can change shaft sealer easily, because wherein part is made up of two semicircular bodies, be convenient to the fast assembling-disassembling maintenance.
