The specific implementation mode is as follows:

the invention will now be further described with reference to specific embodiments, with reference to fig. 1:

the utility model provides a flange wheel, includes installation axle 1, gyro wheel 2, the axial is provided with installation shaft hole 3 in the gyro wheel 2, and install the upper end of axle 1 and insert and establish in installation shaft hole 3, and install axle 1 and rotate with gyro wheel 2 through first bearing 4, the second bearing 5 that sets up of interval from top to bottom respectively and be connected, and gyro wheel 2 is connected with installation axle 1 through first bearing 4, second bearing 5, rotates in a flexible way.

During the installation, the utility model discloses an installation axle 1 sets up along vertical direction, and installs the lower extreme of axle 1 and insert and establish in the frame of conveyer, generally need insert and establish two, is located the both sides of conveyer belt respectively, blocks the conveyer belt, prevents the off tracking, also has certain effect of rectifying simultaneously.

Specifically, the upper end of the mounting shaft 1 is provided with a reducing portion 6, the upper end of the corresponding mounting shaft hole 3 is provided with a first reducing portion 7, a first shoulder 8 is formed between the reducing portion 6 and the mounting shaft 1, a second shoulder 9 is formed between the first reducing portion 7 and the mounting shaft hole 3, and the lower end of the first bearing 4 is limited on the first shoulder 8 and the second shoulder 9.
