When two excitation components 2 are mounted on the base 1, excitation motors are mounted at the same ends of the two rotating shafts 4, the base 1 generates an approximately linear motion track, and the vibration exciter is mounted on a vibrating screen plate which generates vibration similar to a straight line.
The oil cavity shell 5 is provided with an oil inlet and an oil outlet. And a circulating oil system can be connected between the oil inlet and the oil outlet, and the circulating oil system comprises a circulating oil pipe, a circulating oil pump and an oil tank. The addition of the circulating oil system can improve the lubrication effect on the bearing 6 and the rotating shaft 4, but it does increase the possibility of oil leakage and oil seepage, and if the circulating oil system cannot work normally, the oil interruption of the vibration exciter is caused to damage the bearing 6. In winter, the viscosity of the lubricating oil is increased, the oil cannot flow back in time when entering the oil cavity 8, and the oil surface of the lubricating oil in the oil cavity 8 rises, so that oil leakage can be caused at the rotating shaft 4 of the vibration exciter. The design structure of the vibration exciter can well lubricate the bearing 6 in the oil cavity 8 without adopting a circulating oil system, so that fault points are reduced, and the performance is stable.
The two oil cavity shells 5 are internally provided with oil throwing assemblies which are arranged on the rotating shaft 4, and the oil throwing assemblies throw lubricating oil to bearings 6 in the corresponding oil cavity shells 5 and lubricate the bearings 6. The oil slinging component can sling lubricating oil at the lower part in the oil cavity 8 of the oil cavity shell 5, the slinged lubricating oil enters the bearing 6, the lubricating effect on the bearing 6 is improved, and further, the bearing 6 can be well lubricated by keeping the lower lubricating oil level in the oil cavity 8, so that the risk of oil leakage is reduced.

The lubrication falling outside the annular hook 21 can flow into the oil return groove 17 through the outside of the annular hook 21, and the design of the conical surface 22 facilitates the flow of the lubrication into the oil return groove 17. The connection flange 20 and the annular hook 21 shield the gap between the hook-type oil slinger 14 and the end cover 13, preventing the lubricating oil from oozing out of the gap therebetween.
The inner sealing assembly 12 comprises an inner cover 27 and a sealing cover 28, the inner cover 27 comprises an annular outer connecting plate 29, the outer connecting plate 29 is fixed on the oil cavity shell 5, an annular oil groove bulge 30 is arranged on one side, close to the oil cavity 8, of the inner end of the outer connecting plate 29, the inner diameter of the oil groove bulge 30 is identical to that of the outer connecting plate 29, an annular oil groove 31 is arranged on the oil groove bulge 30, the sealing cover 28 comprises an inner annular sleeve 32, a hook bulge 33 is arranged on one side, close to the oil cavity 8, of the outer end of the inner annular sleeve 32, an annular sealing hook 34 with a hook-shaped cross section is arranged on one side, close to the outer connecting plate 29, of the outer end of the hook bulge 33, and the hook end of the sealing hook 34 stretches into the oil groove 31. The lubricating oil on the upper part of the inner cover 27 directly enters the oil groove 31 along the inner cover 27, oil drops on the upper part of the oil cavity shell 5 fall on the sealing hook 34, then enter the oil groove 31 along the sealing hook 34, the hook-shaped structure of the sealing hook 34 is just buckled in the oil groove 31, and thus the lubricating oil cannot seep to the outside of the oil cavity shell 5 along the gap between the oil groove bulge 30 and the hook bulge 33, and the oil leakage phenomenon is caused.
The inner end of the dustproof labyrinth cover 15 is provided with an inner bulge 23 extending towards the direction of the oil cavity 8, the inner bulge 23 and the inner sleeve 18 are inserted into the inner side of the end cover 13 and are in contact with each other, one side of the end cover 13, which is away from the oil cavity 8, is provided with an outer bulge 24, an annular connecting groove 25 is formed in the outer bulge 24, the dustproof labyrinth cover 15 is provided with a fixing flange 26 matched with the connecting groove 25, and the fixing flange 26 stretches into the connecting groove 25.

The first oil seal 35 is arranged on one side of the end cover 13 and is positioned among the end cover 13, the inner bulge 23 and the outer bulge 24, so that the radial size of the end cover 13 along the rotating shaft 4 can be increased, the oil level of lubricating oil in the oil cavity 8 can be further improved, the axial lubricating effect is improved, and oil leakage can be effectively prevented.

The seal 36 prevents the lubricant from oozing out along the rotating shaft 4.
An oil seal groove is formed in one side, close to the oil cavity 8, of the inner end of the hook protrusion 33, and a second oil seal 37 is arranged in the oil seal groove. The second oil seal 37 is arranged in the sealing groove on the hook protrusion 33, and by adopting the structure, the outer diameter of the sealing cover 28 can be designed smaller, so that the oil level in the oil cavity 8 can be improved, the lubrication of the bearing 6 is improved, and meanwhile, oil leakage can be effectively prevented. Because the inner sleeve 18 and the sealing cover 28 are arranged on the inner side of the oil cavity shell 5, the installation with the middle shell 3 is facilitated, meanwhile, dust can be prevented from entering the oil cavity 8, and corresponding dust prevention is not needed.
The invention can be fixedly arranged below a vibrating screen plate through the base 1, the rotating shaft 4 is longer than the width of the screen plate, and the middle shell 3 is arranged at the lower part of the screen plate. When an excitation component 2 is arranged on the base 1, the screen plate can do circular vibration along with the vibration exciter; when two excitation components 2 are arranged on the base 1, the sieve plate can do approximate linear motion along with the vibration exciter, so that the vibration amplitude is improved, and the vibration effect of the sieve plate on materials is improved. Because the exciter is fixed at the lower part of the screen surface, the length of the rotating shaft 4 is large, and if the housing is made into one housing without dividing the housing into two oil cavity housings 5 and one intermediate housing 3, the manufacturing cost of the housing is increased. Meanwhile, if the bearing 6 is lubricated by the lubricating oil, if an oil cavity 8 is adopted, the rotating shaft 4 is slightly deflected during installation and use, so that the lubricating oil in the oil cavity 8 is possibly unevenly distributed, the bearing 6 at one end of the rotating shaft 4 cannot be lubricated, and the other end of the rotating shaft can leak oil.
The beneficial effects of the invention are as follows: when the vibration exciter is installed on the vibrating screen plate, the requirement on installation precision is low, so that the installation is convenient and simple, and the installation cost is reduced; the sealing effect is good, and a higher oil level in the oil cavity can be ensured without causing oil leakage; the oil throwing component and the oil cavity are added to achieve higher oil level, so that the lubrication effect on the bearing is effectively improved, and the service life of the vibration exciter is prolonged.
The above-described embodiments are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art to the technical solution of the present invention should be included in the protection scope defined by the claims of the present invention without departing from the design concept of the present invention.
