The connecting rod bearing removing tool is used when removing the bush or removing the bearing from the bearing seat when the machine is being repaired. On the base plane at both ends are respectively and vertically welded with a column, at the top of the two columns welded with a cross beam, beam and the base plane in parallel; two upright posts are welded between the plate and the base plate, on the plane parallel plate; in the middle there is a round hole. The diameter of the round through hole is slightly larger than the outer diameter of the bush. The bearing plate and the bearing seat which need disassembly are placed on the flat surface; the bearing plate is opposite to the round through hole of the flat plate; the upper end face of the bearing bush is provided with a circular backing plate; the outer diameter of the shim plate is slightly smaller than the outer diameter of the bush. A jack is fixed between the shim plate and the upper cross beam, and the jacking rod of the jack is positioned on the upper plane of the shim plate. Operate the jack so that the ejector rod protrudes and the Bush is pushed into the round through hole of the plate. The effect is that the bush can be removed from the bearing seat and suitable for maintenance. The utility model has the advantages of simple structure and low cost.
【技术实现步骤摘要】
本技术涉及机械维修
,特别涉及一种从轴承座内拆卸轴瓦或拆卸轴 承的专用工具。
技术介绍
连杆轴瓦作为滑动轴承的一种,轴瓦在轴承座内,轴瓦和轴承座二者之间采用的 是过盈配合。在维修更换轴瓦时需要将轴瓦从轴承座上拆卸下来。目前,依靠简单的人工方 法几乎无法将其从轴承座中直接取出轴瓦,通常采用液氮冷却或专用液压设备予以拆除, 但有些工作现场不具备条件。只能将轴瓦和轴承座送到专业维修地点拆除,延长了设备维 修时间。
技术实现思路
本技术的目的是提供一种连杆轴瓦拆卸工具,利用千斤顶的推力,能方便地 使轴瓦与轴承座分离。提高维修工作效率。本技术采用的技术方案是连杆轴瓦拆卸工具,主要由底座、立柱、平板、垫 板、千斤顶和上横梁组成,其特征在于在底座的上平面两端分别垂直焊接有一根立柱,在 两根立柱的顶端焊接有一根上横梁,上横梁与底座的上平面平行;在两根立柱之间焊接有 平板,平板与底座上平面平行;在平板的中部有一个圆形通孔。圆形通孔的直径略大于轴瓦 外径。将需要拆卸的轴瓦和轴承座放到平板上平面,轴瓦与平板的圆形通孔相对;圆形垫板 垫在轴瓦的上端面上,垫板的外径略小于轴瓦外径。在垫板与上横梁之间固定有一个千斤 顶,千斤顶的顶杆顶在垫板的上平面。操作千斤顶使顶杆伸出,轴瓦被顶入平板的圆形通孔 内。为了加强平板的抗压能力,在平板与底座之间垂直焊接有支撑柱,支撑柱在平板 圆形通孔的两侧。为了加强上横梁的抗弯能力,在上横梁与两侧的立柱之间分别焊接有斜拉杆。本技术的有益效果本技术连杆轴瓦拆卸工具,能将轴瓦从轴承座中取 出,适合维修现场使用。结构简单,成本低。附图说明图1是本技术连杆轴瓦拆 ...
