Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure, the anti-reverse clamping stopper bearing filling bearing cage of anti-voussoir that has in embodiment forms primarily of outer ring 1, inner ring 2, keeper body 3, steel ball 4, voussoir 5, Compress Spring 6, seal ring 7 and fixed cover 8.
As shown in Fig. 1 ~ Fig. 4, described keeper body 3 is arranged between outer ring 1 and inner ring 2, the circumferential surface of keeper body 3 is provided with the ball pocket 3a that nine circumferences are uniform, and each ball pocket 3a is built with a steel ball 4; First end face of described keeper body 3 being provided with the voussoir notch 3b that nine circumferences are uniform, in each voussoir notch 3b, a voussoir 5 being housed, is voussoir spaced-apart bosses 3c between adjacent voussoir notch 3b; Described fixed cover 8 is arranged between outer ring 1 first end and inner ring 2 first end, and fixed cover 8 is connected with keeper body 3 first end; Described each voussoir spaced-apart bosses 3c is provided with the spring groove 3d of one end open, the opening end of described spring groove 3d is communicated with the voussoir notch 3b before bearing inner race 2 one-way rotation direction, spring groove 3d is built with Compress Spring 6, described Compress Spring 6 the inner connects keeper body 3, Compress Spring 6 outer end is exposed from spring groove 3d opening end and is withstood voussoir 5, makes voussoir 5 keep fitting with outer ring 1 and inner ring 2 all the time.
As shown in Figure 1, in the embodiment of the present invention, the outside circumference of end face of described inner ring 2 second end extends to form dust cover 2a, and the outer periphery of described dust cover 2a is along the end face inner periphery with outer ring 1 second end along being sealed and matched.In order to improve sealing effect further, the outer periphery of described dust cover 2a, along the end face inner periphery with outer ring 1 second end along the dustproof groove being respectively provided with mutual corresponding matching, is provided with seal ring 7 in dustproof groove.
As shown in Fig. 1 ~ Fig. 3, in the embodiment of the present invention, nine ball pocket 3a and nine described voussoir notch 3b distribute in the circumferentially interleaved of keeper body 3.
In the embodiment of the present invention, the linkage structure of described keeper body 3 and fixed cover 8 as shown in Figure 1 and Figure 2, the voussoir spaced-apart bosses 3c of described keeper body 3 is provided with attachment hole 3e, be provided with the link suitable with attachment hole 3e bottom described fixed cover 8, fixed cover 8 is connected with keeper body 3 with the corresponding matching of attachment hole 3e by link.Described fixed cover 8 and keeper body 3 couple together guarantee voussoir 5 and Compress Spring 6 all in working position.
In the present invention, described keeper body 3 can adopt the versatile material of existing manufacture retainer to make, and preferably adopts nylon material to make.
During concrete installation, when voussoir 5 is correctly installed according to mode shown in Fig. 2, voussoir 5 can load smoothly, coordinates with outer ring 1, inner ring 2; When voussoir 5 fills according to mode shown in Fig. 3 is counter, voussoir 5 upper left corner can produce with the local of keeper body 3 interferes (see Fig. 4), thus causes voussoir 5 to load, and has directly stopped the possibility that voussoir 5 instead fills.
