Design principles of spherical roller bearing
Clicks:13920 Date:11-14
Design principle of roll body
1) material selection principle of roller: stable, practical and convenient. The selection of roller body can be cast stone, steel, ceramics, plastics, composites and so on a wide range of. Different working conditions and different location advantages can also be used for selecting materials nearby. In Jiangxi can be used in Tangshan ceramics, ceramics, such as the selection of steel pipe; a bearing seat of ceramic roller design is good, otherwise the roller beating is too large, on the stability of transport would be bad.
2) roller design, processing principle of roll surface runout, concentric bearing seats at both ends of the mounting section is in line with national standards, should pay attention to the static balance of roll body, in a static state to be able to stop at any position, can stay still good.
3) the roller can be produced in batches and qualified.
Two, axis design principle: according to the market supply, choose Q235 cold drawn round steel, tolerance standard is H6 (no need to use js6 or K6). If using hot rolled round bar. The short axis must use biparietal needle processing (long axis can only use the U-turn car), H6 (the standard is not necessary to use js6 or K6).
Three. Design principle of bearing pedestal
1) material selection principle: practical and convenient. Material selection can be cast iron, plastic, composite materials, steel stamping, a wide range.
2) design, processing principle: bearing and seal installation section of the H6 tolerance or tight point (not too tight, because the roller speed itself is not high, and the bending roll and shaft), and roll body with a tolerance of h6. Bearing and sealing installation segment and roll body matching section should have coaxiality requirements.
