Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces FZ/T 93069-2010 "Rotor Bearings for Rotor Spinning Machines". Compared with FZ/T 93069-2010, the main technology
The changes are as follows.
---The indirect type is removed from the scope (see Chapter 1, Chapter 1 of the.2010 edition)
---Adjust the format of some parameters (see Table 1, Table 1 of the.2010 edition);
---Adjust the heat treatment requirements of the outer ring of the rotor bearing and the mandrel (see 4.1.1, 4.1.1 of the.2010 edition);
---Adjust the requirements for the rolling elements of rotor bearings (see 4.1.2, 4.1.2 of the.2010 edition);
---Improved the requirements for bearing vibration acceleration (see 4.2.1, 4.2.1 of the.2010 edition);
--- Increase the requirements for bearing vibration (see 4.2.2);
---Adjust the requirements of the radial clearance of the rotor bearing (see 4.2.5, 4.2.4 of the.2010 edition);
---Adjust the requirements for the service life of rotor bearings (see 4.2.13, 4.2.12 of the.2010 edition);
---Adjust the measurement method of the temperature rise of the rotor bearing (see 5.9, 5.8 in the.2010 edition);
---Adjusted the sampling method and determination rules (see 6.3,.2010 edition of 6.3).
