Abstract
This utility model refers to an exciter for vibration screen, belonging to the manufacturing field of machine. The shaft of he current exciter is the eccentric shaft, with wide amplitude, thereby easily damaging the bearing and difficultly disassembling and maintaining. This utility model adopts the technical solution for solving the problem: an exciter for vibration screen, including a shaft, a bearing, a scored pulley and an eccentric block. There is one pair of the scored pulleys which is respectively mounted at two ends of the shaft. The shaft is supported by a pair of bearings. The eccentric block is fixed to the scored pulley, wherein the shaft is the straight shaft. This exciter with steady amplitude and long service life is easy to disassemble, can save the maintaining time and improve the work efficiency.
Description
Technical field
The utility model relates to a kind of vibratory sieve vibrator, belongs to mechanical manufacturing field.
Background technology
Vibratory sieve is a kind of important mines benficiation machinery, and screen cloth vibrates under the excitation of vibrator, thereby realizes the sieving and grading of ore.What vibratory sieve adopted usually is the inertia-type vibrator, mainly comprises members such as axle, bearing, sheave, eccentric block.Its axle is an eccentric shaft, bears the vibration task jointly with eccentric block, control vibrator amplitude.The axle of vibrator is rotation at a high speed by driven by motor, and the eccentric body that is installed on the main shaft also rotates thereupon and produce centrifugal intertia force, thereby forces the screen box vibration that is fixed on the vibrator.
Yet in the actual job of muck screening, this vibrator amplitude is bigger, is very easy to damage bearing.In addition, because main shaft is an eccentric shaft, the dismounting trouble, maintenance time is long, has had a strong impact on operating efficiency.
Summary of the invention
The purpose of this utility model is that a kind of amplitude is steady in order to provide, the simple inertia-type vibrator of dismounting, thereby prolongs the service life of vibrator, saves maintenance time, increases work efficiency.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of vibratory sieve vibrator, comprise axle, bearing, sheave and eccentric block, described sheave has a pair of, be installed in the two ends of axle respectively, axle is supported by pair of bearings, and described eccentric block is fixed on the sheave, by it is characterized in that described axle is a d-axis.
The utility model transform the eccentric shaft of common vibratory sieve vibrator as d-axis, and improved vibrator only depends on the high speed of eccentric block to rotate and produces Centrifugal vibration, and its amplitude is steady, and prolong service life; And improved vibrator dismounting is simple, has saved maintenance time, has improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model vibratory sieve vibrator.
The specific embodiment
As shown in Figure 1, the axle of the utility model vibratory sieve vibrator is a d-axis 1, is different from the eccentric shaft of common vibratory sieve vibrator.D-axis 1 two ends are fixed with sheave 2 respectively, have been screwed eccentric block 3 on the sheave 2.D-axis 1 two ends are supported by bearing 4 respectively, and the vibratory sieve screen box is installed on the bearing 4.Can adopt V-type band or the transmission of tire connector between motor and the vibrator.During work, the centrifugal force that the vibration of vibratory sieve vibrator relies on the high speed rotation of eccentric block 3 on the sheave 2 to be produced is realized.
Vibratory sieve vibrator amplitude provided by the utility model is steady, and d-axis 1 is not fragile with bearing 4.If main shaft 1 or bearing 4 damage, only need end slot wheel 2 is unloaded, unclamps bearing 4, axle can be extracted out from the other end, and disassemble and assemble work is simple to operation.
