[0025] Furthermore, the first flange cover 5 and the second flange cover 6 are respectively formed with an inner edge portion, a limiting portion and an outer edge portion from the center to the outside, and the inner edge portion, the limiting portion and the outer edge portion are integrally arranged; the limiting portions of the first flange cover 5 and the second flange cover 6 are combined to form a cavity for accommodating the assembly portion 8.1 of the deep groove ball bearing and the tension wheel flange, and the limiting portions of the first flange cover 5 and the second flange cover 6 are formed with a stepped surface on the inner side surface close to the deep groove ball bearing, which is assembled with the two side end faces of the tension wheel flange assembly portion through the stepped surface.

[0026] Furthermore, the inner edges of the first flange cover 5 and the second flange cover 6 are located on the inner side of the deep groove ball bearing inner ring 2 , and the inner edges of the first flange cover 5 and the second flange cover 6 are attached to each other and fixed by bolts 3 .

[0027] Furthermore, the outer edges of the first flange cover 5 and the second flange cover 6 match the inner diameter side of the support portion 8.2 of the tension wheel flange.

[0028] Furthermore, in order to axially limit the bearing, inner ring limiting ring grooves 2.1 are provided on both axial sides of the inner diameter surface of the inner ring 2, and the first flange cover and the second flange cover are matched and positioned through the inner ring limiting ring grooves.

[0029] Furthermore, the curvature value of the raceway of the outer ring 1 on which the rolling body is assembled is 0.525, and the curvature value of the raceway of the inner ring 2 on which the rolling body is assembled is 0.515.

The first flange cover 5, the second flange cover 6 and the tension wheel flange 8 are matched with the bearing to form an axial limit to the left and right directions of the bearing. Figure 1 shown.

[0032] Due to the high speed of the tension wheel and the tangential forces in multiple directions, the outer ring 1 and the inner ring 2 of the deep groove ball bearing may be displaced, and the rolling element 4 may not run at the center of the raceway. By designing axial limit ring grooves 1.1 and 2.1 on the outer diameter and end face of the outer ring 1 of the bearing, the inner diameter and end face of the inner ring 2, and the first flange cover 5, the second flange cover 6, and the tension wheel flange 8 to fit tightly, the rolling element 4 of the deep groove ball bearing can rotate steadily on the inner and outer ring raceways, withstand radial forces and run at high speed.

This design can greatly increase the limit speed of the bearing. In addition, the retainer 7 adopts a stamping and riveting retainer, and the number of rolling elements can be increased compared with other retainers, which improves the rated dynamic and static loads of the bearing, and the bearing and the tension wheel can withstand greater cutting forces. The new design of deep groove ball bearings can keep the tension wheel in the gang saw machine continuously tensioned and run smoothly, which increases the service life of the bearing. The tension wheels can also be densely arranged to ensure the cutting capacity of the equipment.
