Vibration reduction fastener of abrasion-free limiting device
The invention relates to a vibration reduction fastener of a non-abrasion limiting device. The vibration reduction fastener comprises an upper base plate (2), a lower base plate (3), a fastening bolt (4), a bolt bush (5) and a vibration reduction pad (14). Kidney-shaped holes (21) are formed in the two ends of the upper base plate (2), and corresponding kidney-shaped grooves (31) and screw holes (32) in the kidney-shaped grooves (31) are formed in the two ends of the lower base plate (3). The bolt bush (5) comprises an inner-layer bush (5a), a rubber spring (5b) and an outer-layer bush (5c), and the outer-layer bush is in a hollow column shape matched with the kidney-shaped hole; a flange (5c ') is formed on the upper end face of the bolt bushing, the inner-layer bushing is arranged in the outer-layer bushing in a sleeved mode, a through hole is formed in the upper surface of the inner-layer bushing, the rubber spring is arranged in a gap between the inner-layer bushing and the outer-layer bushing, and the fastening bolt is used for fixing the upper base plate and the lower base plate together and exerting pre-tightening force on the bolt bushing to enable the bolt bushing to be pre-deformed.
本发明涉及一种无磨耗限位装置的减振扣件，包括上垫板(2)、下垫板(3)、紧固螺栓(4)、螺栓衬套(5)以及减振垫(14)。上垫板(2)的两端形成有腰型孔(21)，下垫板(3)的两端形成有相应的腰型槽(31)以及在腰型槽(31)中的螺孔(32)；螺栓衬套(5)包括内层衬套(5a)、橡胶弹簧(5b)以及外层衬套(5c)，外层衬套形成为具有与腰型孔配合的中空柱形，并且在上端面形成有凸缘(5c’)，内层衬套套设在外层衬套之中，在内层衬套的上表面上形成有通孔，橡胶弹簧设置在内层衬套与外层衬套之间的间隙中；紧固螺栓用于将上垫板和下垫板固定在一起，并且对螺栓衬套施加预紧力使之预变形。
