Description

Technical Field

[0001] The utility model relates to the technical field of wet grinders, in particular to a bearing seat device for an ultrafine grinding wet grinder. Background Art

[0002] Traditional structure (CN201120058975.1-Ultrafine grinding wet mill): The output shaft of the reducer is connected by a coupling with bolts. This structure has a large load on the reducer. The reducer not only needs to provide the rotational force required for the rotation of the stirring shaft, but also because the stirring shaft is long and has a certain weight, and the stirring material is a slurry, the reducer needs to bear the upper and lower axial forces and radial forces generated during work, so the force situation of the reducer is very complicated. Conventional right-angle shaft gearbox reducers are not suitable for this working condition at all. The gearbox can only be customized or the model of the gearbox can be greatly increased. However, from the perspective of force analysis, the structure is still not reasonable. Therefore, the failure rate of the reducer with this structure is high and the life is short. Because the gearbox is customized or increased, the cost of the gearbox is also high. At the same time, if the reducer fails, the stirring shaft must be lifted out and disassembled together, which is troublesome to repair. Summary of the invention

[0003] The utility model aims to overcome the deficiencies of the prior art and provide a bearing seat device for an ultrafine grinding wet grinder.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A bearing seat device for an ultrafine grinding wet grinder comprises a main shaft, a bearing seat and a stirring shaft, wherein the bearing seat is fixedly connected to the top of the wet grinder; the main shaft is rotatably sleeved in the bearing seat, the main shaft is a hollow shaft, and the output shaft of the reducer is transmission sleeved in the shaft hole of the main shaft and drives the main shaft to rotate; the lower end of the main shaft is fixed to the upper end of the stirring shaft by bolts.

[0006] Furthermore, the lower end of the main shaft and the upper end of the stirring shaft are positioned by a concave-convex structure.

[0007] Furthermore, a positioning groove is provided at the lower end of the main shaft, and a positioning boss matched with the positioning groove is provided at the upper end of the stirring shaft.

[0008] Furthermore, the output shaft of the reducer is connected to the main shaft via a flat key.

[0009] Furthermore, two bearings are arranged in an upper and lower interval inside the bearing seat.

[0010] The utility model adopts the above technical solution, and has the following beneficial effects:

[0011] 1. The lower end of the main shaft is connected to the agitator shaft by bolts, and the agitator shaft is stressed by the main shaft. The main shaft is a hollow shaft, and the output shaft of the reducer is inserted into the hollow shaft, and a flat key is used for transmission. The reducer of this structure only provides rotational force, which greatly simplifies the stress of the reducer. If the reducer fails, the reducer can be disassembled alone without removing the agitator shaft;

[0012] 2. A bearing is arranged at the top and bottom of the bearing seat so that it can withstand both axial force and radial force. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention is further described in detail below with reference to the accompanying drawings and specific implementations:

[0014] Figure 1 It is a cross-sectional view of the utility model;

[0015] Figure 2 for Figure 1 Enlarged view of point A in . DETAILED DESCRIPTION

[0016] like Figure 1-2 As shown, the utility model is a bearing seat device for an ultrafine grinding wet mill, comprising a main shaft 1, a bearing seat 2 and a stirring shaft 3, wherein the bearing seat 2 is fixedly connected to the top of the wet mill by bolt connection. The main shaft 1 is rotatably sleeved in the bearing seat 2, the main shaft 1 is a hollow shaft, and the output shaft of the reducer 5 is transmission sleeved in the shaft hole of the main shaft 1 and drives the main shaft 1 to rotate. The lower end of the main shaft 1 is fixedly connected to the upper end of the stirring shaft 3 by bolt connection.

[0017] The lower end of the main shaft 1 and the upper end of the stirring shaft 3 are positioned by a concave-convex structure. Specifically, the lower end of the main shaft 1 is provided with a positioning groove 11, and the upper end of the stirring shaft 3 is provided with a positioning boss 31 adapted to the positioning groove 11. Through the above positioning structure, a reliable connection between the main shaft 1 and the stirring shaft 3 can be achieved.

[0018] The output shaft of the reducer 5 is connected to the main shaft 1 via a flat key, which is convenient for disassembly and assembly.

[0019] In the utility model, two bearings 4 are arranged at intervals in the upper and lower parts of the main shaft 1 bearing seat, and a bearing 4 is arranged in the upper and lower parts of the bearing seat 2, so that it can bear both axial force and radial force. The lower end of the shaft is connected to the stirring shaft 3 by bolts, and the stirring shaft 3 is subjected to force on the main shaft 1. The main shaft 1 is a hollow shaft, and the output shaft of the reducer 5 is inserted into the hollow shaft, and a flat key is used for transmission. In this structure, the reducer 5 only provides a rotational force, which greatly simplifies the force situation of the reducer 5. If the reducer 5 fails, the reducer 5 can be disassembled alone without disassembling the stirring shaft 3.

[0020] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications are all within the scope of protection of the present invention.
