Abstract
The utility model belongs to a negative pressure type combination copper coin sealing for mangler shafts and bearings in building machinery field, in particular to a negative pressure type combination copper coin sealing for the mangler shaft and the bearing of an extruder.According to the sealing structure of the utility model, a large shaft seal mud sleeve is sleeved on a main shaft for sealing a rear bearing.A large shaft seal cover for the large shaft seal mud sleeve is clamped to the main shaft.The large shaft seal cover is connected with a large shaft bearing box into one piece.A copper coin sealing member is adopted to seal the front bearing.The copper coin sealing member is fixed to the main shaft via a spring, a spring seat and a large shaft sealing box.The combination sealing of the utility model has the advantages of no air leakage during the usage process, reasonable and compact structure, longer usage period, improved operating efficiency, lowered maintenance time and cost and reasonable design.The normal usage period of the combination sealing is up to two years.
Description
Technical field
The utility model belongs to particularly building material machinery technical field of machinery manufacturing technology field.
Background technique
Packing seal is adopted in the big shaft sealing of tradition extruder, will have compressibility and flexible filler such as asbestos rope and put into Stuffing box, with its axial pressure, makes filler produce radially elasto plastic deformation with gland, stops up the gap, realizes sealing.Subject matter is poor sealing performance, consumes greatly, and macro-axis is easy to wear, and filler is changed frequent, causes inefficiency, and labor intensity increases, and causes the extruder difficult forming, and green body quality is inferior, can not adapt to real using effect.
Summary of the invention
The utility model purpose provides a kind of negative pressure type combination copper coin sealing that is used for extruder mangler shaft and bearing, by complete sealing configuration combination, it is air tight that it is sealed in practical process, rational in infrastructure, life cycle prolongs, increase work efficiency, reduce engineering time and expense, improve the quality of products.
Specifically, the negative pressure type of mangler shaft and bearing combination copper coin seals, and has to be enclosed within the macro-axis sealing clay cover that on the main shaft rear bearing is sealed, and the macro-axis sealing clay is applied mechanically big gland retainer plate and is clamped on the main shaft, and big gland retainer plate and macro-axis bearing box connect as one; Adopt the copper coin Sealing that fore bearing is implemented sealing simultaneously, the copper coin Sealing adopts spring, spring seat and macro-axis sealing case to be fixed on the main shaft.
Combination seal of the present utility model, in the using process sealing air tight, rational in infrastructure, life cycle prolongs, and increases work efficiency, it is reasonable to reduce engineering time and fee structure compact design, never gas leakage, normal life cycle can reach 2 years.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is installed in schematic representation on the extruder for the utility model.
Embodiment
As shown in Figure 2, be used for the negative pressure type combination copper coin sealing of extruder mangler shaft and bearing, have the macro-axis sealing clay cover 3 that is enclosed within on the main shaft 1 rear bearing 11 sealings, macro-axis sealing clay cover (3) is clamped on the main shaft 1 with big gland retainer plate 4, and big gland retainer plate 4 and macro-axis bearing box 5 connect as one; Adopt 6 pairs of fore bearings of copper coin Sealing 10 to implement sealing simultaneously, copper coin Sealing 6 adopts spring 7, spring seat 8 and macro-axis sealing case 9 to be fixed on the main shaft 1.The tank filler sleeve of big gland retainer plate 4 seals with seal ring 2 with the hole simultaneously.
The utility model negative pressure type combination seal is that extruder main shaft and mud cylinder cooperatively interact and finish extruding and form negative pressure of vacuum and extrude the main structure constituent element of base substrate, be the strong point be again seal point, on main shaft 1, assemble fore bearing 10 during assembling, rear bearing 11, refill and join macro-axis bearing box 5, assemble macro-axis sealing case 9 then, with copper coin sealing plate 6, by spring 7, spring seat 8 compresses finishes the copper coin hermetic unit, macro-axis stuffing box gland 3 and big gland retainer plate 4 are being installed, and equipped hole seal ring 2, all assemblings are finished, form the intact mangler shaft of a cover, the sealing of bearing negative pressure type copper coin.The utility model is installed on the extruder as A place among Fig. 1, and Fig. 2 is an A place structure for amplifying among Fig. 1.
Claims (2)
1. be used for the negative pressure type combination copper coin sealing of extruder mangler shaft and bearing, it is characterized in that having and be enclosed within main shaft (1) and go up macro-axis sealing clay cover (3) rear bearing (11) sealing, macro-axis sealing clay cover (3) is clamped on the main shaft (1) with big gland retainer plate (4), and big gland retainer plate (4) connects as one with macro-axis bearing box (5); Adopt copper coin Sealing (6) that fore bearing (10) is implemented sealing simultaneously, copper coin Sealing (6) adopts spring (7), spring seat (8) and macro-axis sealing case (9) to be fixed on the main shaft (1).
2. the negative pressure type combination copper coin sealing that is used for extruder mangler shaft and bearing according to claim 1 is characterized in that sealing with seal ring (2) with the hole simultaneously at the tank filler sleeve of big gland retainer plate (4).
