Technical conditions for stamped seats of outer spherical ball bearings, 1 subject content and scope of application
JB/T6363
This standard is now established for outer spherical ball bearings with seats Technical requirements, acceptance, marking and packaging of stamping seats. This standard is applicable to the final inspection and acceptance reference standards for stamping seats manufactured according to GB7809
GB7809 Outer Spherical Ball Rail Bearing Outline Rules 10. Dimensions, shapes, weights and allowable deviations of G3708 cold-rolled steel plates and strips (B710) High-quality carbon purple knotted tree steel thin steel plates and strips GB8597 Rolling bearing packaging
ZBJ11020) Inspection rules for rolling bearings and their product parts 3 symbols
The symbols cited in this standard comply with the regulations of GB7809. Technical requirements
4.1 The material of the punch seat
The material of the punch seat is made of No. 08 or No. 10 cold-rolled steel plate, and the technology of the steel plate used The requirements should comply with the regulations of (13710), and its thickness tolerance should comply with the provisions of Class B accuracy in GB 08. 4.2 Maintenance requirements of the stamping seat
4.2.1 Under normal working conditions, the inner spherical surface of the stamping seat The diameter of the measuring tape should be i7. If there are special requirements, it can be implemented according to the drawing and the agreement between the two parties. 4.2.2 The limit deviation of the spherical center height H of the punch seat and the screw hole N should be as specified in Figure 1.

4.5 The spherical surface in the stamping seat must be smooth and without scratches. JB/T6363
4.6 The stamping seat is not allowed to have gaps, sharp angles, burrs and cracks. 4.7 In addition to complying with the above regulations, the stamping seat should also comply with the provisions of the product drawings. 5 Inspection methods and acceptance rules
5.1 Spherical diameter D of the stamping seat. , check with an instrument according to the two-point measurement method. 5.2 The spherical center height of the stamped vertical seat is H. Check with the instrument as shown in Figure 5. Figure 5
Place the stamped vertical seat on a flat surface and place the probe at the lowest point of the mating surface. Measure h reading, calculate the H value according to the formula: H
where: D. The actual measured value of the spherical diameter. | |tt |
5.4 The stamping seat should be accepted according to ZBJ11020. The acceptable quality level AQL value of the primary item is 2.5; the secondary item is 4.0. The inspection level is -
General inspection level I, and the major items and minor items are specified in the table below. If the subscriber has other requirements, it shall be determined through negotiation between the subscriber and the manufacturer. Stamping seat finished product sampling inspection items
Serial number
Main inspection items
The limit deviation of the spherical diameter D of the stamping seat
The limit deviation of the spherical center height H of the stamping vertical seat The limit deviation of the screw hole N of the stamping vertical seat
Punching round seat, The limit deviation of the side length N of the screw hole on the triangular seat and the diamond seat and the position of the axis of the screw hole. The contact width between the spherical surface in the single-piece stamping seat and the outer spherical surface of the bearing
6 Marking, packaging and storage ||tt| | Serial number | | tt | | 1 | Comply with product drawings. 6.2 The finished stamping seats that pass the final inspection should be packaged according to GB8597. 6.3 Under normal storage and transportation conditions, the product stamping seat should be guaranteed not to rust within one year. The anti-rust period is calculated from the date of shipment. Additional notes:
This standard is proposed by the National Rolling Bearing Standardization Technical Committee. This standard was issued by the Luoyang Bearing Research Institute of the Ministry of Machinery and Electronics Industry and was responsible for drafting it. The drafter of this standard is Yang Ying.
