Abstract
Description
technical field
[0001] The invention relates to a dust removal device, in particular to a gap reversing sheave mechanism for a single-suction dust removal unit, and belongs to the technical field of dust removal devices. Background technique
[0002] The gap reversing sheave mechanism in the single-suction dust removal unit is mainly used to realize the gap reversing of the suction port. In the design of the sheave gap mechanism, when the crank wheel center distance a and the number of grooves Z are determined, the outer diameter R of the sheave is Fixed value, the gap between the limit wheel and the lever on the crank wheel enters and exits the arc groove and U-shaped groove of the sheave in turn. When the limit wheel is about to leave the arc groove of the sheave, the lever has not yet entered the U-shaped groove. At this time, there is a free zone between the crank wheel and the sheave, and mechanical interference between the crank wheel lever and the U-shaped notch of th...

Embodiment Construction
[0026] see Figure 1~Figure 4 , a gap reversing sheave mechanism of the present invention, which includes a cooperating sheave 1 and a crank wheel 2, the crank wheel 2 is provided with a limit wheel 2.1 and a lever 2.2, and the outer circle of the sheave 1 is stepped shape, the radius R of the small circle of the sheave 1 remains unchanged, and the radius of the major circle of the sheave 1 increases to the center distance a of the crank wheel 2 .
