How To Properly Install And Rotate The Support
- Mar 02, 2017 -
Rotary support in the factory has been coated with anti-rust oil, and wrapped with a film, this package is generally valid for 3-6 months rust. Its storage temperature should be 20 ± 10 ℃, and the relative humidity of not more than 60%, more than the validity period, should be timely maintenance. Rotary support inventory should be filled with grease after one year and check the flexibility of its rotation.

Install the bearing mounting surface rough rotation support roughness is not greater than Ra = 12.5,6.3μm, the installation plane of the flatness of the error to detect the circumferential error and radial error. The circumferential tolerance value corresponds to the standard value range with the size of the slewing ring diameter (see the relevant standard, the radial error is based on the actual width of the flange, and the radial plane tolerance is half of the circumferential tolerance) The

It is important to properly adjust the gear backlash when installing the slewing ring. Can be adjusted at the highest point of the radial runout of the gear with a measure of the ruler, or by pressing the lead wire or other suitable method. If the backlash is not within the value, the movable pinion changes the center distance. Set the rotation after the rotation at least turn a full circle to confirm that there is no other teeth high point, the final support in the rotation after the end of a check back blank gap. The highest point of the radial runout of the gear is marked with green paint in the tooth groove.
