[0024] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1 to Figure 5 The bearing seat with dustproof function shown in the figure includes a mounting base 1 and a mounting top seat 2, and the mounting top seat 2 is fixedly mounted on the top of the mounting base 1 by bolts. A containing chamber is formed between the mounting base 1 and the mounting top seat 2, and a rotating shaft 3 is rotatably penetrated inside the containing chamber, and a ball bearing is arranged inside the containing chamber. Positioning rings 4 are arranged on both sides of the mounting base 1, and the positioning rings 4 are fixedly connected to the rotating shaft 3. The outer ring of the positioning ring 4 is fixedly connected to the fan blade 5, and the fan blade 5 is arranged in plurality, and the plurality of fan blades 5 are evenly distributed around the positioning ring 4, and the inclination directions of the fan blades 5 on both sides of the mounting base 1 are opposite.

[0026] When the rotating shaft 3 rotates following an external motor or other driving device, it will drive the positioning ring 4 to rotate, thereby causing the fan blades 5 to rotate. Since the inclination directions of the fan blades 5 on both sides are opposite, the gas flows from the mounting top seat 2 to both sides, sucking away the dust to achieve the dust-proof function. At the same time, it can also absorb the heat generated during the operation of the bearing seat to achieve the heat dissipation function.

[0027] By providing the positioning ring 4 and the fan blades 5 and installing the fan blades 5 on both sides of the base 1 with opposite inclination directions, the functions of dust prevention and heat dissipation are achieved at the same time, thereby improving the use efficiency of the bearing seat.

[0028] The positioning ring 4 and the fan blades 5 rotate along with the rotating shaft 3, thereby achieving the purpose of energy saving.

[0029] In the specific configuration, the positioning ring 4 includes a first half ring 11 and a second half ring 12. The first half ring 11 and the second half ring 12 are plugged together end to end and fastened by screws 13, so that the positioning ring 4 is fixedly installed on the rotating shaft 3 and is easy to disassemble and assemble.

[0030] In order to protect the fan blades 5 and other structures, circular sleeves 7 are provided on both sides of the mounting base 1 . The circular sleeves 7 surround the outer side of the rotating shaft 3 and also surround the outer sides of the positioning ring 4 and the fan blades 5 .

[0031] In the specific configuration, the circular sleeve 7 includes a first half sleeve 8 and a second half sleeve 9, wherein the first half sleeve 8 is fixedly connected to the mounting base 1, and the second half sleeve 9 is fixedly connected to the mounting top seat 2. When the mounting base 1 and the mounting top seat 2 are connected and assembled, the first half sleeve 8 and the second half sleeve 9 can be butt-jointed and installed synchronously.

[0032] A circular hole 6 is formed through the side wall of the circular sleeve 7, and the circular hole 6 is located between the corresponding positioning ring 4 and the mounting base 1. There are multiple circular holes 6, and the multiple circular holes 6 are evenly distributed. When the rotating shaft 3 rotates with the driving device such as an external motor, the positioning ring 4 is driven to rotate, thereby causing the fan blades 5 to rotate, and the external air enters the circular sleeve 7 through the circular hole 6 and is discharged from the end of the circular sleeve 7 away from the mounting base 1. At the same time, the connection between the rotating shaft 3 and the mounting base 1 and the mounting top seat 2 can be sucked.

[0033] A filter screen can be arranged at the circular hole 6 to filter the dust in the air.

[0034] The outer side of the circular sleeve 7 is provided with a slip ring 10, and the width of the slip ring 10 is greater than the inner diameter of the circular hole 6. When the rotating shaft 3 is in a non-rotating state, the slip ring 10 can be slid toward the circular hole 6 to close the circular hole 6, so as to achieve the effect of preventing dust from connecting the rotating shaft 3 with the mounting base 1 and the mounting top seat 2.

[0035] The top of the mounting top seat 2 is penetrated with an oil inlet groove 14, and the inner thread of the oil inlet groove 14 is connected with a sealing plug 15. When in use, the sealing plug 15 is opened, and lubricating oil can be added into the bearing seat through the oil inlet groove 14.
