  Key points for installation and maintenance of slewing bearing

  Slewing bearing is a kind of large-scale bearing which can withstand the comprehensive load of axial load, radial load and overturning moment at the same time, and the special structure of supporting, rotating, transmission, fixing and so on. Therefore, in the installation of slewing bearing must do a good job of the relevant inspection, or installation needs to pay attention to the matter, for this large-scale bearings, we must do a good job of maintenance, storage and so on, so as to avoid the slewing bearing of the following damage, resulting in normal use.

  1, slewing support bearing installation

  Slewing bearing before the installation, the first to the installation of the host to check, the support should have sufficient strength, the connection surface should be machined, surface roughness and burr. For the machine can not be machined to achieve the required flatness, it is possible to use a special injection strength plastic filler, to ensure the accuracy of the installation plane and to reduce vibration. The ring of slewing bearing has a hardening soft zone, which is labeled "s" on the end of the ring, and should be placed in a Seizikon or non load area (always located at the soft belt).

  When installing slewing bearing, the advanced behavior should be positioned, the bolt should be tightened and the slewing condition of the bearing should be checked. Tighten the bolts should be sufficient preload force, the preload should be the bolt material yield limit of 70%. The mounting bolts shall be fitted with a leveling washer and the spring washer is strictly prohibited.

  2. Maintenance of slewing bearing

  Installed and put into operation slewing bearing in continuous operation after 100 hours, should be fully checked the installation of the preload of the bolts of the moment to meet the requirements of each successive operation 500 hours repeat the above-mentioned inspection once. Slewing bearing bearings should be filled with the right amount of grease, and should be filled with rotating bearings to make the grease evenly distributed. Slewing Bearing in the work after a period of time, will inevitably lose part of the grease, so the normal operation of the slewing bearing 50-100 hours after each interval should be added to the grease.

  3. Transport and storage of slewing bearings

  Bearing in the transport process, should be placed in the level of transport, should prevent sliding and vibration prevention measures, if necessary, auxiliary support.
