Preferably, described locking element is nut, and the outer ring of bearing body is provided with the outside thread being positioned at spacing flange front, and nut spinning is on outside thread, and resilient pad fastens through nut and spacing banjo clip.Under this structural design, adopt the direct spinning of nut on the outer ring of bearing body, thus resilient pad is fixedly clamped by the cooperation realizing nut and spacing flange, have structure simple, the dismounting of resilient pad is more convenient, and nut is to the reliable lock of resilient pad.
Preferably, the endoporus of described resilient pad and the outer ring outer peripheral surface Spielpassung of bearing body.Under this structural design, be convenient to the installation of resilient pad on the one hand, on the other hand, be convenient to the distortion aligning of resilient pad.
Preferably, described nut outer peripheral surface is provided with anti-skidding breach, and the outer peripheral surface of spacing flange is also provided with anti-skidding breach.Under this structural design, be convenient to the operation of dismounting nut, namely facilitate the installation and removal of resilient pad.
Preferably, described distortion groove is the arc strip extended along the endoporus of resilient pad.
Described distortion groove is hollow slots.
Described distortion slot length correspondence 1/1 to two/3rd circular arc is long.
The length direction two ends of described distortion groove are the reaming that aperture becomes large.
Under this structural design, the structural design of distortion groove, the distortion for resilient pad has good guiding function, is convenient to the distortion aligning of resilient pad.
Preferably, described resilient pad connects through arc tangent plane away from housing coupling part side, and it is broadside, opposite side narrow limit structure that resilient pad forms corresponding housing joint side through arc tangent plane.Under this structural design, the material of resilient pad reduces, and reduces costs.
Below in conjunction with accompanying drawing, the utility model is further described.
