Abstract
The utility model discloses a novel box-type vibration exciter lubricated by thin oil. The vibration exciter comprises a cover plate, a ventilating plug screw, an oil drain plug, shaft-end pressing plates, eccentric blocks, balancing weights, elastic cylindrical pins, spacer bushes, shaft sleeves, oil slingers, a case, a long shaft, labyrinth covers, through-hole covers, bearings, bevel wheels and a short shaft. The cover plate is installed above the case to prevent the lubricating oil from leaking. The ventilating plug screw can reduce the temperature rise of the box-type vibration exciter. The oil can flow out by unscrewing the oil drain plug when needing draining. The shaft-end pressing plates are installed at the two ends of the long shaft and the two ends of the short shaft to press the eccentric blocks. The balancing weights are fixed to the eccentric blocks through the elastic cylindrical pins to adjust the exciting force of the vibration exciter. The long shaft and the short shaft penetrate through center holes of the parts such as the bevel wheels, the bearings, the oil slingers, the shaft sleeves, the labyrinth covers, the spacer sleeves and the eccentric blocks. The through-hole covers are fixed to the case through bolts, and are matched with the labyrinth covers so that labyrinth grooves can be formed. The through-hole covers are provided with felt, breathability is good, dust will not enter the vibration exciter easily, the service life of the bearings is prolonged, and installation and maintenance are facilitated.

The utility model is that the technical scheme that technical solution problem is taked is:
A kind of novel box type thin oil lubrication type vibrator, comprise cover plate, ventilative plug screw, bleeder plug, shaft end pressure plate, eccentric block, balancing weight, elastic cylindrical pin, spacer, axle sleeve, disc, casing, major axis, labyrinth lid, through hole lid, bearing, helical gear, minor axis, the top that described cover plate is arranged on casing prevents that lubricating oil from leaking outside, described ventilative plug screw can reduce the temperature rise of box vibrator, when described bleeder plug is drained the oil, this bleeder plug is turned on oil is flowed out, described shaft end pressure plate compresses eccentric block at the two ends of major axis and minor axis, described balancing weight is fixed on the size of adjusting exciting force of exciter on eccentric block by elastic cylindrical pin, described major axis and minor axis run through respectively helical gear, bearing disc, axle sleeve, labyrinth lid, spacer, the centre bore of each parts such as eccentric block, described through hole cover bolt be fixed on casing and with labyrinth lid between coordinates generation maze trough.
Described through hole covers and is provided with felt, good permeability and being difficult for into dust.
On described casing, be provided with spill port, the oil that described disc throws away flows back in casing again by spill port.
Described ventilative plug screw can reduce the temperature rise of box vibrator, when described bleeder plug is drained the oil, this ventilative plug screw is turned on oil is flowed out.
The utility model arranges at the two ends of major axis and minor axis the shaft end pressure plate that is used for compressing eccentric block, balancing weight is fixed on eccentric block by elastic cylindrical pin, eccentric block connection for transmission bearing and axle sleeve by major axis two ends connect motor, realize the normal operation to vibratory sieve.Whole vibratory sieve joined two box vibrators of the present utility model, can make vibratory sieve produce raw rectilinear motion; If the rotating speed of vibratory sieve needs to adjust, on bearing block and motor, belt pulley is installed, can adjust the rotating speed of vibrator.
Positive beneficial effect of the present utility model is as follows:
1, sealing means: by through hole cover with labyrinth lid between coordinates generation maze trough, and cover and be provided with felt at through hole, need not add oil sealing, and good permeability, be difficult for into dust, extended the service life of bearing.
2, thin oil lubricant: thin oil lubricant temperature rise is low, and filling cycle is long.
3, lubricating system: casing is provided with spill port, through hole covers and is also provided with oil groove, and thin oil can have been got rid of and by through hole, covered oil groove after oil and again flow back in casing to spill port by disc.
4, the kind of drive: motor drives the major axis of vibrator by bearing block joint transmission axle, helical gear is equipped with in vibrator inside, and noise is low, stable drive.
5, the utility model volume is little, compact conformation, and balancing weight is bolted on the size of adjusting exciting force of exciter on eccentric block, can under rugged environment, work, and is difficult for into dust, good permeability; And be convenient to installation and maintenance.
