Another kind is to adopt single stuffing box bearing, its seal lubrication structure as shown in Figure 1, sprocket wheel 1 rotates the upper end portion that is assemblied in the transmission shaft 2 that an above-below direction extends by being assemblied in single stuffing box bearing 3 in the sprocket wheel 1 central shaft bearing hole, the sealed end of single stuffing box bearing 3 is downward, the open end upwards, pass at transmission shaft 2 on the upper end of sprocket wheel 1 and be coated with the sealing gland 5 that is used to seal single stuffing box bearing 3 open ends, the upper end that is positioned at sealing gland 5 on transmission shaft 2 is provided with the set screw nut 6 of fixing seal gland 5, the upper end that transmission shaft 2 passes sprocket wheel 1 is provided with lubricating cup 4, offers the lubrication channel in the oiling agent feeding bearing that makes in the lubricating cup 4 in transmission shaft.Though this seal lubrication structure is simple, the lubrication channel of offering in the transmission shaft has reduced the intensity of transmission shaft, has shortened the working life of transmission shaft; When the sprocket wheel on the corn harvester adopted this seal lubrication device, the end of transmission shaft was also twined corn stem and broken leaf easily.
Summary of the invention
The purpose of this utility model is to provide a kind of seal lubrication structure of sprocket wheel inner bearing, causes transmission shaft short technical problem in working life to solve prior art owing to offer lubrication channel in transmission shaft.
For achieving the above object, the utility model adopts following technological scheme: the seal lubrication structure of sprocket wheel inner bearing, comprise the sprocket wheel that is used for rotating the transmission shaft upper end portion that is assemblied in vertical setting by single stuffing box bearing, single stuffing box bearing is installed in the bearing saddle bore that centre of sprocket offers, be provided with lower limit retaining edge, single stuffing box bearing outer ring in this bearing saddle bore, be provided with end cover at a sprocket wheel end up with single stuffing box bearing open end and transmission shaft end seal, the lubricating cup that is used for injecting lubricant oil in single stuffing box bearing is installed on the sealing end cap, the lower end surface of end cover outer rim cooperates with the bearing outer ring block, be equiped with hole jump ring in the bearing saddle bore, be provided with the oil duct that is communicated with lubricating cup and single stuffing box bearing between end cover and the single stuffing box bearing the upper-end surface axial limiting of end cover outer rim.
Described lubricating cup is arranged on the central position of end cover.
Described retaining is along being wholely set with sprocket wheel.
The seal lubrication structure of sprocket wheel inner bearing, comprise the sprocket wheel that is used for rotating the transmission shaft upper end portion that is assemblied in vertical setting by single stuffing box bearing, single stuffing box bearing is installed in the bearing saddle bore that centre of sprocket offers, be provided with in this bearing saddle bore the hole with jump ring to single stuffing box bearing outer ring to lower limit, be provided with end cover at a sprocket wheel end up with single stuffing box bearing open end and transmission shaft end seal, the lubricating cup that is used for injecting lubricant oil in single stuffing box bearing is installed on the sealing end cap, be provided with the tapped hole section of spiral connection end cover on the sprocket wheel in the upper end of bearing saddle bore, the edge of end cover lower end surface cooperates with the bearing outer ring block, is provided with the oil duct that is communicated with lubricating cup and single stuffing box bearing between end cover and the single stuffing box bearing.
Described lubricating cup is arranged on the central position of end cover.
The utility model uses end cover that sealing is realized in the open end of single stuffing box bearing, can prevent that impurity such as dust from entering bearing, the lubricating cup that is provided with on the end cover can make lubricant oil be injected in single stuffing box bearing, and oil duct is arranged on to need not to make between end cover and the single stuffing box bearing offers lubrication channel in the transmission shaft; The end of transmission shaft is arranged on and can prevents in the end cover that corn stem and broken leaf are wrapped in the transmission shaft end.
