Embodiment

Please refer to Fig. 1 to shown in Figure 6, the concrete structure that it has demonstrated the preferred embodiment of the utility model includes flexible bearing 10, end cap 20, cam 30, crosshead shoe 40, coupling 50 and jump ring 60.

Wherein, this end cap 20 is tabular ringwise, and this end cap 20 is butted on the interior edge face of circle 11 within flexible bearing 10; This cam 30 is suitable and be installed in the inner ring 11 of flexible bearing 10 and form the ripple hair device with the inner ring 11 of flexible bearing 10; This crosshead shoe 40 be butted within this flexible bearing 10 on the exterior edge face of circle 11 and with cam 30 engagement connections; This coupling 50 pass successively crosshead shoe 40, cam 30 and end cap 20 and with crosshead shoe 40 engagement connections; This jump ring 60 is snapped in the inner of coupling 50 and props up on the interior edge face of end cap 20.

In the present embodiment, the exterior edge face of this cam 30 is concaved with two first chutes 31, the interior edge face of this crosshead shoe 40 convexes with two first fixture blocks 41 accordingly, and this two first fixture block 41 axially is sticked in the first corresponding chute 31, so realizes crosshead shoe 40 and cam 30 engagement connections.And, be provided with two second chutes 51 on this coupling 50, the exterior edge face of this crosshead shoe 40 convexes with two second fixture blocks 42 accordingly, and this two second fixture block 42 axially is sticked in the second corresponding chute 51, so realizes coupling 50 and crosshead shoe 40 engagement connections.
