Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, this utility model is a kind of high class gear for automobile engine,
Including gear 1, the gear teeth 2, teeth groove 3, arc angling 4, bearing 5, centrifugal self-locking device 6, axis hole 7, radiating groove 8, louvre
9, screw 10, it is characterised in that: the outer wall of described gear 1 is uniform-distribution with the gear teeth 2, has one between adjacent two gear teeth 2
Teeth groove 3, described teeth groove 3 bottom land both sides are provided with arc angling 4, and the inwall of described axis hole 7 is installed with bearing 5, and described bearing 5 wraps
Including outer ring 51, inner ring 52, retainer 54, rolling element 53, described rolling element 53 is fixed on outer ring 51 and inner ring by retainer 54
Between 52, described outer ring 51 is fixing with axis hole 7 inwall to be connected, and is provided with centrifugal self-locking device 6 between described inner ring 52 and outer ring 51,
Described centrifugal self-locking device 6 includes that projection 61, described projection 61 are installed on inner ring 52 outer wall, and described projection 61 is relative to interior
The other end that circle 52 connects is provided with groove 63, is provided with the slide block 62 that can slide in groove 63, described groove in described groove 63
Be provided with back-moving spring 64 between 63 diapires and slide block 62, described outer ring 51 inwall be provided with can with the draw-in groove 65 of slide block 62 clamping,
