Spaced reversing grooved wheel mechanism

Abstract

The invention belongs to the technical field of dust removing equipment, and relates to dust removing equipment, in particular to a spaced reversing grooved wheel mechanism for a single-suction dust removing unit. The spaced reversing grooved wheel mechanism comprises a grooved wheel (1) and a crankwheel (2), which are matched with each other. A limiting wheel (2.1) and stirring rods (2.2) are arranged on the crankwheel (2). The outer circle of the grooved wheel is step-shaped. The radius R of a small circle of the grooved wheel (1) remains unchanged, and the radius of a large circle of the grooved wheel (1) is increased to be a center distance a of the crankwheel (2).

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...

[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 groove wheel 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 break away from 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 the sheave is likely to occur due to the vibration of the equipment during operation and the imbalance of the transmission mechanism, which in turn causes the crank wheel Fracture and other failures
