Abstract
The utility model relates to a shaft type vibrator of a vibrating screen, belonging to the field of vibrating screening machines and aiming at solving the problems of leakage, high bearing temperature rise and difficult maintenance and disassembling of the current vibrator. The shaft type vibrator is composed of a bearing seat, a bearing, an eccentric shaft, an eccentric block, a shaft housing and the like; wherein a cylindrical roller bearing is installed at one end of a vibrator shaft, and a double-row self-aligning roller bearing is installed at the other end of the vibrator shaft; a round rubber sealing ring is installed at a gap position formed by a chamfering edge and a bearing cover, and the chamfering edge is intersected at the outer end face of the bearing seat and an inner hole; an oil hole for enabling communication of the inner cavity and the outer cavity of the bearing is processed on the bearing seat; a decompression oil thrower with an L-shaped cross section is sleeved at a part on a journal in contact with the bearing cover; an oil throwing surface of the oil thrower close to one end of the bearing is conical; and an oil throwing gap is kept between the oil throwing surface and an inner conical surface on the bearing cover, and the other end of the bearing and the bearing cover are sealed by using a lip-type sealing ring. The shaft type vibrator of the vibrating screen has the characteristics of stable running, good sealing, low bearing temperature rise and convenience for installation and maintenance and can be applied to the vibrating screens of various shaft type vibrators.
Description
Technical field
The utility model belongs to the vibration screening machinery field, and the nothing that mainly relates to use on the vibratory sieve is leaked, temperature rise is low and well behaved vibratory sieve shaft type vibrator.
Background technology
The shaft type vibrator of using on the vibratory sieve mainly is made up of bearing block, bearing, eccentric shaft, eccentric block and axle vestlet etc.Eccentric shaft is installed in through bearing and bearing block on the side plate of screen box, and described bearing generally is to adopt two double-row self-aligning roller bearings.The sealing of vibrator also is to adopt conventional encapsulating method.Because the working environment of vibratory sieve is relatively abominable, and the position of bearings at both ends is distant.Service time of a specified duration the expansion that leakage of oil, axle take place easily of its sealing position the temperature rise of bearing is increased, and have the problem of maintenance and dismounting difficulty.The leakage of vibrator not only influences production, also environment is polluted simultaneously.
Summary of the invention
The purpose of the utility model provides a kind of vibratory sieve shaft type vibrator, and this vibrator operates steadily, good seal, bearing temperature rise are low, and easy to installation and maintenance.
The utility model is realized through following measure.Mainly be made up of bearing block, bearing, eccentric shaft, eccentric block and axle cover, it is characterized in that: the end at vibrator shaft is equipped with cylinder roller bearing, and the other end is equipped with double-row self-aligning roller bearing; At the chamfering place of bearing block outer face and endoporus handing-over, the round rubber sealing ring is housed with the formed interstitial site of bearing cap; Be processed with the oil through that bearing cavity and exocoel are communicated on the bearing block at two ends, the quantity of oil through is 2-10 on each bearing block; The position that on axle journal, contacts with bearing cap is set with the L-shaped decompression disc of cross section; Disc is conical near the pasta that gets rid of of bearing one end, and and bearing cap on internal conical surface between leave and get rid of oil-gap, getting rid of oil-gap is the 3-4 millimeter, adopts the lip-type packing sealing between the other end and the bearing cap; The coning angle that taper shape gets rid of pasta is 70-90 °; The axle journal in the bearing cap outside is provided with labyrinth ring, forms labyrinth sealing with bearing cap.Described shaft type vibrator is the vibrator that eccentric shaft vibrator, piece eccentric type vibrator or eccentric shaft and piece off-centre are used simultaneously.
The beneficial effect of the utility model is that employing cylinder roller bearing and double-row self-aligning roller bearing supporting on vibrator shaft is keeped in repair mounting or dismounting conveniently, can compensate the expansion of eccentric shaft in operation process, the minimizing bearing heating.Round rubber sealing ring between bearing block and the bearing cap can axially with radially seal it simultaneously, prevents to reveal.L shaped decompression disc has alleviated the pressure of oil pressure to lip-type packing in the rigid bearing inner ring.The effect that prevents oil leakage has all been played in oil through on the bearing block and the labyrinth sealing on the bearing cap etc. preferably simultaneously.So this shaft type vibrator have operate steadily, the temperature rise of good seal, bearing is low and installation and maintenance characteristics easily, can be applicable on the vibratory sieve of various shaft type vibrators.
