JB/T 10236-2014Rolling bearings - Specifications of vibration (velocity) for tapered roller bearings (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces JB/T 10236-2001 "Rolling bearings - Specifications of vibration (velocity) for tapered roller bearings". Compared with JB/T 10236-2001, the main technical changes are as follows:

- MODIFY the scope of application of the standard (see Chapter 1; Chapter 1 of the 2001 edition);

- MODIFY the division method of vibration (speed) limits (see Table 1; Table 1 of the 2001 edition);

- MODIFY the vibration (speed) limits of small-size tapered roller bearings (see Table 1; Table 1 of the 2001 edition);

- ADD the vibration (speed) limits for large-size tapered roller bearings (see Table 1);

- MODIFY the vibration (speed) measurement method of tapered roller bearings (see Chapter 6; Chapter 5 of the 2001 edition);

- ADD the vibration (speed) limits for large taper angle tapered roller bearings (see Appendix A).

1 Scope

This standard specifies the technical conditions for vibration (speed) of single-row tapered roller bearings, which have a nominal outer diameter of 30 mm ~ 200 mm.

Group V specified in this standard is the basic requirement for vibration (speed) of general bearings. Group V1, Group V2, Group V3 are suitable for bearings which have higher requirements for vibration (speed).

This standard applies to production inspection and user acceptance of tapered roller bearings.
