Problems solved by technology

However, these two kinds of bearings have direct contact between the bearing and the shaft. Such bearings will generate a lot of friction when the machine is running, causing a lot of energy loss; at the same time, friction will shorten the service life of the machine; moreover, the bearing The friction on the machine will also produce a lot of noise, which is harmful to the health of technicians who use this machine
[0003] The gas bearing disclosed in Chinese Patent No. CN 86104100 avoids the direct contact between the bearing and the shaft and can greatly reduce the friction loss, but the bearing cannot bear the axial thrust, and the structure is complicated, the operation is inconvenient, and the practicability is low

Abstract

A high-precision dynamic gas transmission device for corrugating machinery, which comprises a shaft and a shaft sleeve, the shaft sleeve is provided with evenly distributed ventilation holes, and a gas flow control valve is installed on each row of the ventilation holes, and the shaft shoulder is provided with a gas flow control valve. A seal is installed, and the gap between the shaft and the shaft sleeve is filled with high-pressure gas injected from the vent hole; the end of the shaft enclosed in the shaft sleeve is provided with an annular groove, and at least three displacement sensors are installed on the shaft sleeve The displacement sensors are respectively electrically connected with the PLC central processing unit through the data acquisition system, and the PLC central processing unit is connected with the gas flow control valve installed on the vent hole. The invention can effectively reduce the running friction, save more than 20% of energy, effectively reduce the noise generated by running, prolong the service life of the machine, and increase the running speed by more than 40%.

Description

technical field [0001] The invention relates to a dynamic gas transmission device, in particular to a high-precision dynamic gas transmission device for corrugated machinery. Background technique [0002] At present, the transmission system of corrugated machinery for manufacturing corrugated paper cores of packaging materials mainly adopts shaft transmission, and the bearings used for shaft transmission mainly include rolling bearings and sliding bearings. However, these two kinds of bearings have direct contact between the bearing and the shaft. Such bearings will generate a lot of friction when the machine is running, causing a lot of energy loss; at the same time, friction will shorten the service life of the machine; moreover, the bearing The friction on the machine also produces a lot of noise, which is harmful to the health of technicians who use this machine. [0003] The gas bearing disclosed in Chinese Patent No. CN 86104100 avoids the direct contact between the b...
