Description

Technical Field

[0001] The utility model belongs to the technical field of vibrating screens, and in particular relates to a double-set bearing seat for a vibrating screen which is easy to maintain. Background Art

[0002] The vibrating screen works by utilizing the reciprocating vibration generated by the vibrator excitation. The upper rotating counterweight of the vibrator causes the screen surface to produce planar gyratory vibration, while the lower rotating counterweight causes the screen surface to produce conical gyratory vibration. The combined effect causes the screen surface to produce complex gyratory vibration. Its vibration trajectory is a complex spatial curve, which is projected as a circle on the horizontal plane and an ellipse on the vertical plane.

[0003] In the prior art, there is a double-assembly-supported vibrating screen with application number: 201620062462.0, which includes a first assembly-supported vibrating screen and a second assembly-supported vibrating screen. The first assembly-supported vibrating screen and the second assembly-supported vibrating screen have the same structure and are connected in parallel. The first assembly-supported vibrating screen includes a triangular connector, a bearing seat, a main shaft, and an external connector. The bearing seat is sleeved in the middle of the main shaft. Two bearings are provided in the bearing seat, and a bearing spacer is provided between the two bearings.

[0004] In the above, the triangular connector and the external connector are connected to the two ends of the bearing, which basically achieves relative stability during bearing rotation. However, after reading the technical solution, it is learned that the component that ensures the close fit between the bearing and the main shaft is the bearing spacer. This spacer will deform under long-term use and the pull of centrifugal force, resulting in different sealing effects at both ends of the main shaft. Furthermore, during the subsequent maintenance of the main shaft, the deformed spacer needs to be cleaned, which seriously affects the maintenance efficiency of the bearing and the main shaft.

DETAILED DESCRIPTION

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0023] The present invention provides a double-set bearing seat for a vibrating screen that is easy to maintain, including an external mechanism 100; for example, Figure 1-Figure 3 shown.

[0024] The external mechanism 100 includes an eccentric shaft 103, and the eccentric shaft 103 is equipped with a locking mechanism 200 and a disassembly mechanism 300. The disassembly mechanism 300 includes a steel sleeve 301 sleeved on the top outer surface of the eccentric shaft 103, and a labyrinth plate 302 is placed on the top of the steel sleeve 301. The outer side surface of the eccentric shaft 103 is equipped with a bearing 304, and the outer surface of the bearing 304 is provided with a bearing cover 303.

[0025] A counterweight 306 is provided on the upper surface of the labyrinth plate 302 . The counterweight 306 is an integrally formed double-ring block. A synchronous wheel 307 is provided on the end surface of the eccentric shaft 103 .

[0026] The surface of the steel sleeve 301 is sleeved with a sleeve 101 , and the end surface of the sleeve 101 is provided with a triangular rib 102 , and the upper surface of the triangular rib 102 is matched with the end cover 305 .

[0027] Specifically, by coordinating the external mechanism 100 with the locking mechanism 200 and the disassembly mechanism 300, one end of the eccentric shaft 103 can still be sealed and secure when the other end is being repaired, thereby indirectly improving the maintenance efficiency of the eccentric shaft 103. The sleeve of the steel sleeve 301 and the eccentric shaft 103 can prevent the eccentric shaft 103 from excessively shifting during movement, thereby ensuring that the eccentric shaft 103 can continue to rotate within a normal range. The coordinating arrangement of the labyrinth plate 302, the bearing 304 and the bearing cover 303 ensures that the surface of the eccentric shaft 103 is always sealed and supported, and will not fall or deviate during maintenance, thereby improving the maintenance efficiency of the eccentric shaft 103. The safety of the bearing cover 303 during maintenance is improved. The setting of the counterweight body 306 can improve the rotation accuracy of the eccentric shaft 103 by increasing the weight, reduce the excessive displacement of the eccentric shaft 103 during disassembly and maintenance, and the bearing cover 303 will not have obvious position offset. The matching setting of the synchronous wheel 307 allows the eccentric shaft 103 to obtain rotational power. Furthermore, the matching setting of the sleeve 101 and the triangular rib 102 strengthens the surface stability of the steel sleeve 301, thereby ensuring that the eccentric shaft 103 always moves in the inner cavity of the sleeve 101, indirectly reducing the difficulty of maintaining the bearing cover 303.

[0028] The side of the bearing cover 303 is provided with an end cover 305; for example, Figure 2-Figure 4 shown.

[0029] The inner cavity of the end cover 305 cooperates with the labyrinth plate 302 , and the inner side of the labyrinth plate 302 is sleeved with the eccentric shaft 103 .

[0030] The center of the labyrinth plate 302 is kept coincident with the center of the synchronous wheel 307 , and a locking disk 201 is placed at the bottom of the bearing cover 303 .

[0031] The surface of the locking disc 201 is provided with an alignment seat 202 , and the lower surface of the alignment seat 202 is provided with a pulley 203 . The inner cavity of the pulley 203 is adapted to be installed with the eccentric shaft 103 .

[0032] Specifically, through the cooperation between the end cover 305 and the labyrinth plate 302, after the bearing cover 303 is squeezed by centrifugal force, the deformation generated is quickly offset by the end cover 305 and the labyrinth plate 302, reducing the structural damage of the bearing cover 303. Through the cooperation between the locking plate 201 and the alignment seat 202, the outer surface of the eccentric shaft 103 is firmly supported. At the same time, the adaptive installation of the pulley 203 allows the eccentric shaft 103 to rotate evenly.

[0033] The number of the triangular ribs 102 is two; for example, Figure 3-Figure 5 shown.

[0034] The two triangular ribs 102 are symmetrically arranged on the sleeve 101 .

[0035] The outer surface of the synchronous wheel 307 is provided with adapting protruding teeth, and the multiple adapting protruding teeth are arranged in a ring array.

[0036] Specifically, the symmetrical arrangement of the triangular ribs 102 prevents the sleeve 101 from being over-extruded, thereby ensuring the structural integrity of the sleeve 101 , further adapting to the annular array arrangement of the convex teeth, and improving the transmission accuracy of the synchronous wheel 307 .

[0037] Working principle: After braking the vibrating screen device, first rotate the sleeve 101 to make it unscrew from the top of the locking plate 201, thereby exposing the internal eccentric shaft 103. Then rotate the steel sleeve 301 and the labyrinth plate 302, so that the bearing cover 303 and the bearing 304 placed at the bottom of the labyrinth plate 302 rotate synchronously.

[0038] When the bearing cover 303 needs maintenance, it is necessary to install a counterweight 306 on the end face of the eccentric shaft 103, and install a locking disk 201 and a positioning seat 202 on the other end to keep the two ends of the eccentric shaft 103 relatively balanced. Then remove the external bearing cover 303, and then install a new bearing cover 303 according to the wear condition of the internal bearing 304. Then, re-install the bearing 304 and the eccentric shaft 103, and fix the end cover 305 and the outer surface of the bearing cover 303 for secondary tightening of the bearing cover 303. Finally, install the pulley 203 and the synchronous wheel 307 on the connecting port of the eccentric shaft 103 respectively, so that the eccentric shaft 103 with the new bearing cover 303 can rotate smoothly, completing the process of vibrating the material.
