A pouring structure of the end cover of a support wheel

The utility model discloses a pouring structure of an end cover of a supporting wheel. The pouring structure is a symmetrical structure on a sand box. The pouring structure consists of a straight runner, a straight runner is located at the center of the pouring structure, and the lower part of the runner is symmetrically set up with a cast-in-place road one, one end of the cast-in-place road is connected with the straight runner, and the other one is one of the runner. The end symmetry setting has a runner two, the runner two is vertical to the runner, and the runner two is set with a riser. The lower part of the riser is arranged with an inner runner. The straight runner is connected by the runner one, the runner two, the riser and the inner runner, and the inner runner is connected to the ear plate with the bolt hole on the end cover and the shaft end cover one end. The hole passes through the core molding; the runner, the runner one, the runner two, the riser, the inner runner and the end cover and the sand box are arranged with grooves, and the covered sand is filled in the grooves. The utility model adopts a casting structure of the end cover of the supporting wheel, which can solve the problems of casting defects such as shrinkage cavity and shrinkage.

一种支重轮端盖的浇注结构
本技术涉及支重轮端盖的铸造
,尤其是涉及一种支重轮端盖的浇注结构。
技术介绍
支重轮用来支撑挖掘机的重量,同时在履带的导轨或履带板面上滚动,还用来限制履带,防止履带横向滑脱,挖掘机转向时,支重轮迫使履带在地面上滑移。支重轮包括轮体、轮轴、轴套、密封圈、油封和端盖,轮体通过轴套安装在轮轴上,油封装配在封槽内,并在油封另一侧与轮轴之间设置端盖,端盖与轮轴固定,并由密封圈密封。端盖具有支撑轮轴的作用,端盖的一端设置有耳板,耳板上设置有装配用的螺栓孔。端盖采用铸造的方式生产,螺栓孔由后续的机加工制成,因端盖的耳板较厚所以在铸造过程中易产生热节,在耳板内部产生缩孔、缩松等铸造缺陷。
