The external cause of gear noise in horizontal band saw gear grinding machine
 
 
 
 
For the same gear pair of a horizontal band saw, the noise in the working state is different from that in the test state. If the part related to the working state of the gear has unreasonable design or manufacturing and assembly, even if many noise reduction measures are taken for the gear itself, There is still a lot of noise. Therefore, to reduce the gear noise of the horizontal band saw, attention should be paid to controlling the external reasons. The main thing is to ensure that the drive shaft has sufficient rigidity to ensure the accuracy of the box hole and make the box have enough For important high-speed gears, the stiffness z should be reduced to eliminate the clearance between the shaft hole and the key side.
 
The noise of the horizontal band saw holder comes from the impact between the holder and the vibrating broken work when the bearing rotates. This noise mainly occurs on the ball bearing and the tapered night bearing. The radial clearance is too large and the lubrication performance is poor. This kind of noise can be generated under the conditions of transmission of torsion fluctuation on the shaft, etc., to prevent the noise or vibration of the cage, use a good lubricant; reduce the radial clearance or reduce the bearing installation error and improve the manufacturing accuracy of the cage.
 
Dehumidification, vacuum, microwave, and advanced dry weather all use clean electricity as energy, and they have characteristics. Their applications have been increasing. Although solar energy is a renewable clean energy, due to the weakness of intermittent heating and gas supply, It is estimated that there will be no significant growth in the application of solar drying technology in the short term. Take Japan as an example. Japan had approximately 1,648 drying rooms from 1991 to 1995, of which steam drying, dehumidification drying, vacuum drying, solar drying and other drying accounted for 81.3%, 9.2%, 5,3%, 1% and 3.2%, 2 The results of the drying and suffocation statistics of the Japan Wood Drying Association on the 2830 question in only one year, the proportions of the above-mentioned drying methods have changed respectively It is 64, 5%, 26%, 2,7%, 0, 8% and 6%. According to the statistics of Japan, the growth of dehumidification and drying is relatively obvious, but the temperature of dehumidification and drying is low, and it is generally used for pre-drying. The steam drying chamber generally has a large capacity. If calculated according to the drying capacity, steam drying in Japan accounted for about 70% in 2∞0. On the surface, vacuum drying in Japan seems to have a downward trend. In fact, in recent years, Japan’s High-frequency-vacuum, microwave-vacuum combined drying has increased, and this combined drying is included in other items in the statistics.
