Pivot type movable point rail frog antifriction device
The invention provides a pivot type movable point rail frog antifriction device which is characterized in that pivot spacer iron is fixedly arranged between a long point rail and a short point rail, the pivot spacer iron is downwards and fixedly provided with a bearing device, and the bearing device is composed of a bearing seat and a rotating shaft rotationally connected with the bearing seat; a positioning table corresponding to the bearing device is fixedly arranged on the base plate, a positioning key is fixedly arranged on the inner side of the positioning table, and a positioning groove matched with the positioning key is formed in the side face of the bearing device; after the antifriction device is installed, the bearing device is embedded into the positioning table, and the positioning key is embedded into the positioning groove. Sliding friction generated when the long and short point rail assemblies are moved is changed into rolling friction of the bearings through the bearing devices, the switching resistance is reduced, the structure is simple, installation is convenient, and the rigid requirement of the pivot movable point frog can be met.
本发明提供一种枢轴式可动心轨辙叉减摩装置，长心轨与短心轨之间固定设置有枢轴间隔铁，所述枢轴间隔铁向下固定设置有轴承装置，所述轴承装置由轴承座以及与所述轴承座转动连接的转动轴构成；垫板对应所述轴承装置固定设置有定位台，定位台内侧固定设置有定位键，所述轴承装置侧面设置有与所述定位键匹配的定位槽；减摩装置安装完毕后，所述轴承装置嵌入所述定位台，所述定位键嵌入所述定位槽。本发明通过轴承装置将长短心轨组件搬动时的滑动摩擦变为轴承的滚动摩擦，降低了切换阻力，结构简单、安装方便，能够适用于枢轴可动心辙叉的苛刻要求。
