Problems solved by technology

[0003] The mechanical structure commonly used in textile machinery is composed of various rollers, rollers, guide rollers, rollers, brush rollers and other rollers. When the textile machinery is running, the rollers on these rollers or fast Or slow operation, the rotation of the roller shaft will inevitably bring wear, especially the brush roller, the brush roller will use time, and the weight of the brush on its surface will be seriously unevenly distributed, which will cause the brush roller to rotate when the brush roller rotates. Serious vibration is generated, which not only affects the effect of the products produced, but also accelerates the aging of the machinery

Abstract

The invention provides a dynamic balance adjusting device for a roll shaft. The dynamic balance adjusting device comprises a counterweight ring sleeved on the roll shaft, and a cylindrical cavity radially arranged on the counterweight ring. A rod-free piston is arranged in the cylindrical cavity, a water injection passage is arranged at one end of the cylindrical cavity, the water injection passage is communicated with the water injection port arranged on the outer surface of the counterweight ring, a water valve is arranged on the water injection port, the water injection passage side of the rod-free piston is filled with water, and the non-water-injection passage side of the rod-free piston is filled with air. Water is used as a counterweight, weight of the counterweight can be adjusted infinitely, and accordingly a dynamic balance index of the roll shaft is more accurate.

Description

technical field [0001] The invention relates to the field of dynamic balance adjustment equipment, in particular to a roller shaft dynamic balance adjustment device. Background technique [0002] Commonly used machinery contains a large number of parts for rotating motion, such as various transmission shafts, main shafts, motors and rotors of steam turbines, etc., collectively referred to as rotary bodies. Ideally, when the revolving body is rotating and not rotating, the pressure on the bearing is the same, and such a revolving body is a balanced revolving body. However, due to various factors such as uneven material or blank defects, errors in processing and assembly, and even asymmetrical geometric shapes in design, the various rotating bodies in the project make the rotating body rotate. The centrifugal inertial force generated by each tiny particle cannot cancel each other out. The centrifugal inertial force acts on the machine and its foundation through the bearing, ...
