Abstract
The utility model discloses a main shaft bearing sealing mechanism for a horizontal vibrating centrifuge, and solves the technical problem that a main shaft bearing seal of the conventional horizontal vibrating centrifugal dewatering machine causes oil leakage easily. The main shaft bearing sealing mechanism for the horizontal vibrating centrifuge comprises a horizontal vibrating centrifuge machine seat (1), wherein a main shaft (4) and a bearing seat (12) are arranged in the horizontal vibrating centrifuge machine seat (1); a bowl-shaped inner sealing ring (3) is arranged outside a tapered roller bearing (5); the right side surface of the bowl-shaped inner sealing ring (3) is fixedly connected with the bearing seat (12); an O-shaped sealing ring (6) is arranged between the inner hole wall of the bowl-shaped inner sealing ring (3) and the shaft shin of the main shaft (4); a dual-annular groove (8) is formed in the left side surface of the bowl-shaped inner sealing ring; a bowl-shaped outer sealing ring (2) is fixedly connected with the right side surface of the shaft end (9) of the main shaft (4); a dual-annular bump (7) is formed on the right end surface of the bowl-shaped outer sealing ring (2); the dual-annular bump (7) is movably arranged in the dual-annular groove (8). The sealing performance of a bearing is improved, and the main shaft bearing sealing mechanism for the horizontal vibrating centrifuge has the characteristics of convenience in disassembling and assembling.
Description
Technical field
The utility model relates to a kind of seal arrangement of bearing, particularly a kind of bearing sealing device of horizontal vibrating centrifuge main shaft.
Background technique
The main shaft bearing sealing of horizontal vibration de-watering centrifuge is all the emphasis of artificer's overriding concern all the time, because vibration frequency is high, Oscillation Amplitude is large, and the lubricant oil in bearing is easily revealed, the dust of outside easily enters in bearing, and shortened the working life of bearing.The conventional seals method of existing product is the inner ring of bowl in sealing back-to-back to be installed to two O shape circles in bearing, has oil leakage phenomenon.
Summary of the invention
The utility model provides a kind of horizontal vibrating centrifuge main shaft bearing sealing mechanism, and the main shaft bearing that has solved existing horizontal vibration de-watering centrifuge seals the technical problem of easy leakage of oil.
The utility model is to solve by the following technical programs above technical problem:
A kind of horizontal vibrating centrifuge main shaft bearing sealing mechanism, comprise horizontal vibrating centrifuge support, in horizontal vibrating centrifuge support, be provided with main shaft, left side at horizontal vibrating centrifuge support is provided with bearing support, between bearing support and main shaft, be provided with tapered roller bearing, arranged outside at tapered roller bearing has bowl seal inner ring, right flank and the bearing support of bowl seal inner ring are fixed together, between the inner hole wall of bowl seal inner ring and the axle shin of main shaft, be provided with O-ring seals, on the left surface of bowl seal inner ring, be provided with dual torus groove, on the right flank of the axle head of main shaft, be fixedly connected with bowl seal outer ring, on the right side of bowl seal outer ring, be provided with dual torus projection, dual torus projection is movably arranged in dual torus groove.
Dual torus projection is 1 millimeter with the gap between dual torus groove, is provided with external sealed O shape and encloses between the right flank of bowl seal inner ring and bearing support, at the right-hand member of main shaft, is provided with large belt wheel.
The utility model, when large belt wheel drives main shaft rotating operation, has greatly improved lubrication effect, has increased lubricated area, has greatly improved the sealing of bearing, and has had the feature easily of installing and removing simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
A kind of horizontal vibrating centrifuge main shaft bearing sealing mechanism, comprise horizontal vibrating centrifuge support 1, in horizontal vibrating centrifuge support 1, be provided with main shaft 4, in the left side of horizontal vibrating centrifuge support 1, be provided with bearing support 12, between bearing support 12 and main shaft 4, be provided with tapered roller bearing 5, arranged outside at tapered roller bearing 5 has bowl seal inner ring 3, the right flank of bowl seal inner ring 3 and bearing support 12 are fixed together, between the inner hole wall of bowl seal inner ring 3 and the axle shin of main shaft 4, be provided with O-ring seals 6, on the left surface of bowl seal inner ring 3, be provided with dual torus groove 8, on the right flank of the axle head 9 of main shaft 4, be fixedly connected with bowl seal outer ring 2, on the right side of bowl seal outer ring 2, be provided with dual torus projection 7, dual torus projection 7 is movably arranged in dual torus groove 8.
Dual torus projection 7 is 1 millimeter with the gap between dual torus groove 8, is provided with external sealed O shape and encloses 10 between the right flank of bowl seal inner ring 3 and bearing support 12, at the right-hand member of main shaft 4, is provided with large belt wheel 11.When system motor drives large belt wheel 11 rotations, large belt wheel 11 drives again main shaft 4 and 2 rotations of bowl seal outer ring, bowl seal inner ring 3 is fixed on bearing support 12, rotation in the dual torus groove 8 that the dual torus projection 7 arranging on the right side of bowl seal outer ring 2 arranges on the left surface of bowl seal inner ring 3, this cooperation makes the oil in bearing be not easy to leak, relative movement face designing requirement between them is the gap of 1 millimeter, betwixt between gap by the self oil feeder high temperature-resistant grease of annotating, reach effect lubricated and sealing.
