Ball bearings must it be to determine the distinct approach of repair, which has long been Ball bearings the total advantage of your near destruction of particular judgments appear .

Why the Ball Bearing working so noisy?In our country, the manufacturing technology of large vibrating screen is not dominant, so some vibration sieve equipment or give priority to in order to import, this has brought some problems, mainly reflected in the following aspects: replacement parts to repair, equipment, the equipment utilization rate is low, failed to give full play to the equipment efficiency, affect the further development of enterprises.

1 raceway sound

The sound is due to roller bearing swivel raceway when rolling in the rolling and stimulate a smooth and continuous noise, or tone only if its sound pressure level when aroused great attention. In fact, inspired by the sound of roller acoustic energy is limited, as in normal circumstances, high-quality sound for the 6203 roller bearing 25 ~ 27dB. This noise is to load single row deep groove radial ball bearings for the most typical, it has the following characteristics:

a. noise, vibration is random;

b. vibration frequency at 1kHz or more;

c. Whether the changes in speed, noise, sound pressure level of the main frequency is almost constant and increases with the speed increase;

d. When the radial clearance increases, the sound pressure level increased dramatically;

e. bearing rigidity increases, the total sound pressure level is lower, even if the speed increases, the total sound pressure level has also increased little;

f. lubricant viscosity, the higher the sound pressure level is lower, but for grease lubrication, the viscosity, the shape of soap fiber noise can affect the size of the value. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery ,like jaw breaker, Henan Hongxing is always doing the best in products and service.

Something someone new to an office might not know, but definitely should know: NEVER open two filing cabinet drawers at the same time. Personally, I would not have known this. Most of the newer filing cabinets actually will not let you open more than one drawer at a time. Why is this? Because if you open two at once like one of the girls who used to work in my office did… you will quickly find yourself laying on the ground underneath a tipped over filing cabinet with all of its contents spilling out all over you. Do not worry though, she was fine, but she did learn a valuable lesson to pass on to future employees who found themselves in an office for the first time. (Although I imagine it also made her want to avoid the filing cabinet for the first month following the incident, at least it would have had it been me).

Keeping this possible fatality in mind, filing cabinets can be useful for storage. The drawer slides they employ make it so that the drawer will catch right at the end, making it impossible for the drawers to come all the way out.
