Abstract
The utility model provides a vertical spindle type mechanical base seal device. According to the technical scheme, a vertical spindle type mechanical base seal device comprises oil seals, an upper seal cover, a wool felt, a guard ring, a felt gland, a lower seal cover and a rib sheet, wherein the upper seal cover is fixedly connected with a vertical spindle type mechanical spindle and a rack through a flat key, the lower seal cover is fixedly connected with a vertical spindle type mechanical base through a screw, a group of labyrinths are arranged between end surfaces of the upper seal cover and the lower seal cover, grease is filled in gaps among the labyrinths, the guard ring is arranged on an outer periphery of the upper seal cover, the rib sheet is arranged on an outer periphery of the guard ring, one oil seal is respectively arranged at two ends of an inner hole of the lower seal cover, the wool felt is arranged at the position of the gap between an inner periphery of the upper seal cover and an outer periphery of the lower seal cover and compressed by the felt gland, and the felt gland is fixedly connected with a lower end surface of the upper seal cover through a screw. The vertical spindle type mechanical base seal device has the advantages that a plurality of structural forms are combined for seal, the seal is very reliable, and the defect that seal of the vertical spindle type mechanical base is prone to be damaged is thoroughly eradicated.
Description
Technical field
The utility model relates to a kind of vertical shaft type mechanical pedestal seal arrangement, belongs to machinery lubrication and seal technical field.
Background technique
The much vertical shaft type machinery such as sand cutting machine, edge runner of casting, mineral processing; when design, neglect the significance that ensures base reliable sealing; generally only have single track or double sealing; but the base of this class machinery is in dirt accumulation or even constantly washes away lower running at water and mixtures of materials; its base seal device very easily damages; cause the inner foreign matter of base to be invaded; rolling bearing burns out kills; this class machinery is generally heavier; maintenance base must tear greatly that unload greatly can not open; therefore, base seal damages and causes frequent shutdown to cause very large economic loss.
Summary of the invention
The purpose of this utility model is just to provide a kind of vertical shaft type mechanical pedestal seal arrangement, for addressing the above problem.
The technical solution of the utility model is: a kind of vertical shaft type mechanical pedestal seal arrangement, comprise oil sealing, top cover labyrinth, wool felt, guard ring, felt gland, lower sealing cover and muscle sheet, top cover labyrinth is affixed with flat key connecting mode and vertical shaft type mechanical main shaft and frame, lower sealing cover is affixed with screw attachment mode and vertical shaft type mechanical pedestal, between top cover labyrinth and lower sealing cover end face, be provided with one group of labyrinth, and in labyrinth clearance, fill grease, the excircle of top cover labyrinth is provided with guard ring, the excircle of guard ring is provided with muscle sheet, the endoporus two ends of lower sealing cover are respectively provided with an oil sealing, the excircle gap location of the inner circumference of top cover labyrinth and lower sealing cover is provided with wool felt, and compressed by felt gland, felt gland is affixed with screw attachment mode and top cover labyrinth lower end surface.
The beneficial effects of the utility model are: various structures form combination seal, seal very reliably, and thoroughly effect a radical cure the drawback of vertical shaft type mechanical pedestal sealing sensitive for damages.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, known with reference to accompanying drawing 1, a kind of vertical shaft type mechanical pedestal seal arrangement, comprise oil sealing 3, top cover labyrinth 4, wool felt 5, guard ring 6, felt gland 7, lower sealing cover 8 and muscle sheet 9, top cover labyrinth 4 is affixed with flat key connecting mode and vertical shaft type mechanical main shaft 1 and frame 2, lower sealing cover 8 is affixed with screw attachment mode and vertical shaft type mechanical pedestal 14, between top cover labyrinth 4 and lower sealing cover 8 end faces, be provided with one group of labyrinth, and in labyrinth clearance, fill grease, the excircle of top cover labyrinth 4 is provided with guard ring 6, the excircle of guard ring 6 is provided with muscle sheet 9, the endoporus two ends of lower sealing cover 8 are respectively provided with an oil sealing 3, the excircle gap location of the inner circumference of top cover labyrinth 4 and lower sealing cover 8 is provided with wool felt 5, and compressed by felt gland 7, felt gland 7 is affixed with screw attachment mode and top cover labyrinth 4 lower end surfaces.Working principle of the present utility model is as follows: this seal arrangement divides the combination of three-decker various ways, on the excircle of the top cover labyrinth 4 rotating with main shaft 1, set up a guard ring 6, effect is first to block the direct friction of thick and stiff particle to rotation and gap, static position, prevent that these particles from invading in selfaligning bearing 10 and two-sided thrust ball bearing 11 active chambers, be fixed in the muscle sheet 9 on guard ring 6 cylindricals, can in rotation process, remove again the dirt being attached to around base in time, do not allow it pile up gradually and base is sealed, gap location between top cover labyrinth 4 and lower sealing cover 8 arranges wool felt 5 and adds gland 7 again and seal, effect is to stop the fine grit that enters guard ring 6 to be invaded, its end face is designed to one group of labyrinth seal, in gap, fill grease, it is the core position of whole sealing mechanism herein, under machine normal operation, grit and other medium cannot pass through this group labyrinth seal substantially, the effect of two oil sealings 3 is: one is when with pressure filling seal grease above, avoid entering base 14 inner chambers with the grease of dirt, one is to stop base 14 internal works to adopt the machinery oil of bath lubrication below, excessive under main shaft 1 rotation, in addition, the axially mounting of main shaft 1 adopts upper spherical bearing 12 and lower peripheral surface to support 13 so secondary sphere-contacts, object is to make vertical shaft type machinery under the operating mode of low-speed heave-load, upper beam vibration and even while rocking, can in base 14, obtain micro-aligning, thereby the stable and sealing of guarantee base 14 is reliable.
