[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.
[0022] As Figures 1-6 shown, a silica gel for bearing dust prevention includes a silica gel pad 1. A shaft hole 2 penetrating the silica gel pad 1 is provided at the center of the silica gel pad 1. Three mounting holes 3 penetrating the silica gel pad 1 in a circular array are provided at the edge of the silica gel pad 1. A sunk groove 7 is provided in the middle of the back of the silica gel pad 1, and the sunk groove 7 is located outside the silica gel pad 1. Ring grooves 10 are provided at the edge of the back of the silica gel pad 1 and at the position of the back of the silica gel pad 1 close to the sunk groove 7. The materials of the silica gel pad 1, the convex ring 4 and the arc strip 5 are silica gel.
[0023] This structure adopts silica gel material to better cooperate between the silica gel and the motor bearing, protect the bearing at the connection between the motor and the shaft, and prevent dust and other foreign matters from entering and affecting the normal operation of the motor.
[0024] As Figure 2 , Figure 4 and Figure 5As shown, sealing rings 8 are bonded to the inner walls of both annular grooves 10.
[0025] By using the function of the annular groove 10, the sealing ring 8 is installed at an appropriate position on the silicone pad 1, so that one side of the silicone can cooperate with the mounting piece on the motor, enabling the silicone to be better installed on the outer wall of the shaft.
[0026] Such as Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, double-track grooves 9 are provided at the edges of the front surface of the silicone pad 1, and the double-track grooves 9 are located outside the mounting holes 3. Double-track rubber ring pads 6 are bonded to the inner walls of the double-track grooves 9.
[0027] By using the function of the double-track grooves 9, the double-track rubber ring pads 6 can be installed on the silicone pad 1, so as to cooperate with the positions where the silicone pad 1 and the motor are to be installed, for better sealing and reducing the entry of foreign matters such as dust.
[0028] Such as Figure 5 and Figure 6 As shown, a slope one with a higher inner part and a lower outer part is provided at the center of the front surface of the silicone pad 1, and the slope one is located outside the shaft hole 2.
[0029] By using the function of the slope one, the front surface of the silicone can better fit with the position where the motor is to be installed.
[0030] Such as Figures 4-6 As shown, a slope two with a higher inner part and a lower outer part is provided at the edge of the back surface of the silicone pad 1, and the slope two is located outside the sink groove 7.
