Abstract
The utility model relates to a seal device, more particularly suiting for seal used for a feeder or between a rotary shaft and an endplate for a quenching and tempering device. The utility model is characterized in adopting double seal structure and comprising a rotary shaft, a bearing and a bearing seat; the rotary shaft is provided with an endplate, a sealing part, a press cover, a bearing seat and a bearing in turn. The sealing part is used for sealing between the rotary shaft and the endplate and is pressed into the branch port of the endplate, meeting the purpose of the first layer sealing; a filler 9 is used on the rotary shaft between the press cover and the endplate; a gland box 8 is sleeved outside the filler 9; the press cover 5 and the gland box 8 are fixedly connected through the bolt 7, the nut 14, 116; when the bolt and the nut are screwed tightly, the press cover 5 presses the filler inside the gland box, meeting the purpose of the second layer sealing. The utility model has the advantages of having simple structure, low production cost, good sealing result, long life span for the filler, simple replacing the filler, no needing to replace seal parts because the filler can be used for long time, very conveniently replacing the seal parts and lowering labor strength for workers.
Description
Affiliated technical field
The utility model relates to a kind of seal arrangement, particularly the seal arrangement used of feeder or quality-adjusting device.
Background technique
Generally adopt common seal arrangement at present between the axle head (being running shaft and end plate) of feeder or quality-adjusting device, seal as seal ring, this sealing means exists some defectives, as poorly sealed, it is more serious to scurry material leakage vapour phenomenon, and production environment has been caused very big influence; Moreover seal ring will often change, and is cumbersome.Now along with the client to the improving constantly of product needed, people more and more pay attention to the environment and the sanitary condition of manufacturing shop, so people are seeking a kind of structural type that better axle head is sealed, and scurry material and leak the vapour phenomenon and taken on a new look completely thereby make.
Summary of the invention
The purpose of this utility model provides a kind of novel seal arrangement, scurries material with thorough solution and leaks the vapour phenomenon.
For achieving the above object, adopt following technological scheme: the sealing device adopts double sealing structure, the sealing device mainly comprises running shaft, bearing, bearing support, and end plate, Sealing, gland, bearing support and the bearing of feeder (or quality-adjusting device) is housed on the running shaft successively.By the Sealing sealing, Sealing preferably adopts seal ring between the end plate of running shaft and feeder (or quality-adjusting device), and seal ring preferably adopts the thick nylon sheet material of 8-12mm, and Sealing is compressed into a mouth of end plate, plays the first layer seal action; Filler 9 is housed on the running shaft between gland and the end plate, the filler 9 outer Stuffing boxes 8 that are set with, gland 5 fixes up by bolt 7, nut I4, nut II6 with Stuffing box 8, when tight a bolt, during nut, the gland 5 just filler in the compacting Stuffing box plays second layer seal action.
The beneficial effects of the utility model are: the utility model is simple in structure, and cost of production is low, owing to adopted the scheme of double seal, so shaft end seal is effective, has reached to prevent to seal to scurry the purpose that material leaks vapour between running shaft and the end plate; Simultaneously because the adjusting of bolt, nut, when filler during because of running shaft fretting wear attenuation, can by tight a bolt, nut makes the filler in the Stuffing box be compacted, thereby still can reach desirable sealing effect after making the filler attenuation, and prolonged the working life of filler, can not greatly reduce cost just by subscription rate after wearing and tearing; When filler has not had enough thickness compacting Stuffing boxes through long-time wearing and tearing, can turn on nut simultaneously, take off gland, urgent again again nut behind the replacing filler, it is very laborsaving, easy to change filler like this; Because can using for a long time of filler, so not often replacing of Sealing are also very convenient even if replacing is got up, and have reduced working strength of workers.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. bearing, 2. hold axle bed, 3. running shaft, 4. nut I, 5. gland, 6. nut II, 7. bolt, 8. Stuffing box, 9. filler, 10. seal ring, 11. feeders (or quality-adjusting device), 12. end plates.
Embodiment
Embodiment is: seal arrangement of the present utility model mainly comprises running shaft 3, bearing 1, bearing support 2, and end plate 12, seal ring 10, gland 5, bearing support and the bearing of feeder (or quality-adjusting device) 11 is housed on the running shaft 3 successively.Seal by seal ring 10 between the end plate 12 of running shaft 3 and feeder (or quality-adjusting device) 11.Filler 9 is housed on the running shaft between gland and the end plate 3, the filler 9 outer Stuffing boxes 8 that are set with, gland 5 is tightened by bolt 7, nut I4, II6 with Stuffing box 8, and nut I4 can use high nut, nut II6 thin nut.Seal ring 10 adopts the thick nylon sheet material of 10mm.
Claims (3)
1, a kind of seal arrangement, mainly comprise running shaft, bearing, bearing support, feeder (or quality-adjusting device) end plate, seal ring, gland, bearing support and bearing are housed on the running shaft successively, seal by Sealing between running shaft and the end plate, it is characterized in that on the running shaft between gland and the end plate (3), being equipped with filler (9), the outer Stuffing box (8) that is set with of filler (9), gland (5) is affixed by bolt (7), nut I, II (4,6) with Stuffing box (8).
2, seal arrangement according to claim 1 is characterized in that: the Sealing between running shaft (3) and the end plate is seal ring (10).
