Detailed Description

In order to make the technical field personnel understand the utility model discloses the scheme, will combine the drawing in the embodiment of the utility model below, to the technical scheme in the embodiment of the utility model carries out clear, complete description.

As shown in fig. 1-4, a long-life bearing comprises an inner ring 10 and an outer ring 11, a first retainer 14 and a second retainer 15 are arranged between the inner ring 10 and the outer ring 11, at least two balls 13 are arranged between the first retainer 14 and the second retainer 15, two dust covers 12 are further arranged between the inner ring 10 and the outer ring 11, and the two dust covers 12 are located on one side of the balls 13 far away from the central point of the inner ring 10.

In this embodiment, the first holder 13 is composed of at least two semicircular sections and at least two connecting sections, the connecting section is disposed between two adjacent semicircular sections, and the semicircular sections and the connecting sections are integrally formed;

the second retainer 15 is composed of at least two arc-shaped sections and at least two clamping sections, and each arc-shaped section is continuously connected with the first retainer 14 through the two clamping sections;

furthermore, the number of the semicircular sections of the first retainer 14 is equal to that of the arc-shaped sections of the second retainer 15, the number of the clamping sections of the second retainer 15 is twice of that of the arc-shaped sections, and the ball 13 is positioned in a space defined by each semicircular section of the first retainer 14 and the arc-shaped section of the second retainer 15;

through the setting of 14 semicircle sections of first holder and 15 segmental arcs of second holder, carry on spacingly with ball 13, make ball 13 stably arrange between inner circle 10 and outer lane 11, secondly two joint sections of second holder 15 can be dismantled and set up on first holder 13, when being convenient for follow-up bearing washs, maintains, ball 13 dismantles work.

A first groove 16 is formed in the end face, facing the ball 13, of each arc-shaped section of the second retainer 15, a second groove 18 is formed in the ball 13, the inner wall, away from the first groove 16, of one side of the second groove 18 is semicircular, a rotating shaft 17 is arranged in the first groove 16, and a butting plate 19 extending into the second groove is arranged on the rotating shaft 17 through a torsion spring sleeve;
