Description

一种三级减速双齿形内齿圈
技术领域
本实用新型涉及液压设备零部件技术领域,特别涉及一种三级变速双齿形内齿圈。
背景技术
内齿圈是液压行走装置与行走装备的连接部件,是轮缘上有齿能连续啮合传递运动和动力的机械元件,是多级减速的重要结构支撑部件,广泛应用于冶金、矿山、起重运输、轻化、船舶、农业机械、航空多种领域的设备减速机构中。目前,在国内市场的大型液压行走装置的三级减速内齿圈都是分体的,造成加工与安装的精度降低,制造成本也相对较高。
实用新型内容
本实用新型为了弥补现有技术的不足,提供了一种结构合理、制造成本低、加工精度高的三级减速双齿形内齿圈。
为实现上述目的,本实用新型采用下述技术方案:一种三级减速双齿形内齿圈,包括一体成型的壳体,所述壳体内设有一级齿圈和二级齿圈,所述一级齿圈的内径小于二级齿圈的内径,所述一级齿圈和二级齿圈之间设有一过渡段,所述壳体的两个端面设有安装孔,所述壳体的一级齿圈侧连接行走装置的端盖,所述壳体的二级齿圈侧连接行走机构的内齿圈座。
所述一级齿圈的宽度为96mm,所述二级齿圈的宽度为94mm。
本实用新型的有益效果是:本实用新型在现有分体内齿圈的基础上,将其整合为一体,在铸造方面省工省料,在机加工与插齿方面即省工又能保证较高的加工精度,结构紧凑,体积小,重量轻。
附图说明
图1是本实用新型结构示意图;
图2是图1的左视图,
图3是图1的右视图。
其中1.壳体,2.一级齿圈,3.二级齿圈,4.安装孔,5.过渡段,6、端盖。
具体实施方式
为了更清楚地说明本实用新型实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本实用新型的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动性的前提下,还可以根据这些附图获得其他的附图。
如图1到图3所示的一种三级减速双齿形内齿圈,包括一体成型的壳体1,壳体内设有一级齿圈2和二级齿圈3,一级齿圈2的宽度为96mm,二级齿圈2的宽度为94mm;一级齿圈2的内径小于二级齿圈3的内径,一级齿圈2和二级齿圈3之间设有一过渡段5,壳体1的两个端面设有安装孔4,壳体1的一级齿圈2侧连接行走装置的端盖6,壳体1的二级齿圈3侧连接行走机构的内齿圈座。
上述虽然结合附图对本实用新型的具体实施方式进行了描述,但并非对本实用新型保护范围的限制,所属领域技术人员应该明白,在本实用新型的技术方案的基础上,本领域技术人员不需要付出创造性劳动即可做出的各种修改或变形仍在本实用新型的保护范围以内。
