Abstract
A large gear ring sealing device is arranged between a large gear ring and a gear ring outer cover. The sealing device comprises an oil blocking ring arranged on the side face of the large gear ring, a sealing connecting plate, a pressing plate and a rubber plate. One side of the oil blocking ring is connected to the side face of the large gear ring. The upper portion of the sealing connecting plate is connected with the outer side of the gear ring outer cover. The lower portion of the sealing connecting plate is a rotating groove body. The rotating free end of the rotating groove body and the lower end of the rubber plate are fixedly connected with the pressing plate through connecting pieces. The upper end of the rubber plate is connected with the oil blocking ring in an abutting mode. The large gear ring sealing device is simple in structure, the large gear ring is sealed in a sealed space, during a using process, surplus lubricating oil on the face of a pool is blocked and is guided to flow to the oil pool through the rotating groove body in the sealing connecting plate, lubricating oil leakage is effectively avoided, pollution to external environment is lowered, gear ring abrasion is lowered, service life is prolonged, and maintaining cost is lowered.
Description
Technical field
The utility model relates to a kind of bull gear seal arrangement that the main equipment such as rotary kiln uses that is applied to, and belongs to the mechanical seal field.
Background technique
Now a lot of huge revolving equipment is all used bull gear, for example rotary kiln.Big gear ring of rotary kiln in use, easily makes lubricant oil leak after housing distortion or sealing felt collar wearing and tearing, the severe contamination surrounding working environment, and external dust easily enters the inner oil sump pollution lubricating of gear ring oil, reduces oil, accelerates tooth surface abrasion.Thereby increased the rotary kiln running maintenance cost.
The model utility content
The utility model is for the deficiency existed in background technique, and a kind of bull gear seal arrangement that can play to the lubricant oil on bull gear seal action is provided.
The technical solution adopted in the utility model is: a kind of bull gear seal arrangement, and the sealing device is arranged between bull gear and gear ring outer cover, and described seal arrangement comprises the flinger ring that is arranged on the bull gear side, the plate that is tightly connected, pressing plate and rubber plate; Wherein flinger ring one side is connected with the side of bull gear; The top of the described plate that is tightly connected is connected with the gear ring outer cover outside, and the bottom of the plate that is tightly connected is the revolution cell body, and its revolution free end is fixedly connected with pressing plate with link with the lower end of rubber plate, the upper end of described rubber plate and flinger ring apical grafting.
The outside of flinger ring is included in the revolving structure inside of the plate that is tightly connected.
Rubber plate is the man type rubber plate, and the free end of the lower end of this rubber plate and the plate that is tightly connected fits tightly, and pressing plate is separately positioned on the rubber plate lower end and the free-ended both sides of plate that are tightly connected, and is connected by link.
The gear ring outer cover is arranged on the top of flinger ring near a side of bull gear, and forms labyrinth seal structure with flinger ring and the plate that is tightly connected.
Flinger ring in the sealing device and the plate that is tightly connected are the round structure be complementary with bull gear and gear ring outer cover.
This sealing device structure disclosed in the utility model is simple, bull gear is sealed in airtight space, in using process, make the unnecessary lubricant oil of Chi Mianshang be stopped and be guided to oil sump by the revolution cell body on the plate that is tightly connected, effectively prevent that lubricant oil from leaking, the pollution of minimizing to external environment condition, reduce the gear ring wearing and tearing, increase the service life, reduce maintenance cost.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is bull gear overall structure schematic diagram.
In figure: bull gear 1, flinger ring 2, gear ring outer cover 3, the plate 4 that is tightly connected, support 5, rubber plate 6, pressing plate 7.
Embodiment
Below in conjunction with drawings and Examples to this novel being described further.
Referring to accompanying drawing 1-2, wherein Fig. 1 is also that the A-A of Fig. 2 is to sectional drawing.Gear ring outer cover 3 is sleeved on the outside of bull gear 1, and gear ring outer cover 3 is fixed on support 5.Along the axial direction of bull gear, this novel described seal arrangement is arranged between both sides, bull gear and the gear ring outer cover 3 of bull gear, and the seal arrangement of bull gear both sides is symmetrical arranged.
Flinger ring 2 is arranged on the both sides of bull gear, and a side of flinger ring is fixedly connected with the outer side surface of bull gear.The be tightly connected upper end of plate 4 is fixed on the outside of gear ring outer cover 3, and the bottom of the plate 4 that is tightly connected is the revolution cell body, and this revolution cell body has formed the guiding gutter of lubricant oil, turns round cell body and is connected with the oil groove that is arranged on the bull gear bottom.The revolution free end of revolution cell body is positioned at the below of flinger ring, and the lower end of this free end and rubber plate 6 fits tightly, and is arranged between two pressing plates 7, by links such as connecting bolts, is connected and fixed.Rubber plate 6 is the man type rubber plate, and its lower end is the monomer end, and upper end is the split end.The upper end of rubber plate and flinger ring lower surface apical grafting.
The lower edge of gear ring outer cover 3 is arranged on the flinger ring top, and it and flinger ring form labyrinth seal structure with the plate that is tightly connected, and lubricant oil is leaked and plays inhibition.
Between man type rubber plate and flinger ring, be along bull gear radial elastic rubbing contact.Rubber plate, the plate bottom that is tightly connected, the half new sealing configuration of the outside formation one of flinger ring, flinger ring, gear ring outer cover bottom, the plate that is tightly connected are by forming half sealing structure of rock, and the two combines and forms maze type sealing configuration.
