Detailed Description
The drawings are for illustrative purposes only and are not to be construed as limiting the invention; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The positional relationships depicted in the drawings are for illustrative purposes only and are not to be construed as limiting the invention.
Example 1
As shown in FIGS. 1-2, the present embodiment provides a ventilator impeller 2 dismounting device, which comprises a base 4, a mandril 5, a shaft head protective sleeve 3 and a fastening bolt 6. The base body 4 is of an integral structure, a round hole is formed in the bottom of the base body 4, and the size of the round hole is equal to that of an inner hole of the impeller 2. The spindle head protective cover is arranged at the position of the round hole, the outer diameter of the spindle head protective cover 3 is slightly smaller than that of the round hole, the spindle head protective cover can freely penetrate through the round hole, and the impeller 2 can be conveniently and smoothly pulled out. The shaft head protective sleeve 3 is provided with an internal thread which is screwed with the shaft head of the transmission shaft 1 of the ventilator impeller 2. Waist-shaped holes are formed in two sides of the round hole, fastening bolts 6 are mounted on the waist-shaped holes, the assembling of different center distances of the process holes in the impeller 2 is met, and in the embodiment, the fastening bolts 6 are inner hexagonal cylindrical head bolts. In order to prevent looseness, a flat washer 8 and a spring washer 7 are arranged on the inner hexagonal socket head bolt.
