Abstract

本实用新型公开了一种圆柱滚子轴承，由内滚道、外滚道、圆柱滚子和保持架组成，保持架为空心圆柱体，且空心圆柱体中心空心为圆形；保持架外壁加工有环形凹槽，且环形凹槽底部加工有矩形通孔；矩形通孔长度与圆柱滚子长度相同，宽度与圆柱滚子直径相同；矩形通孔数量与圆柱滚子数量相同；对常规的保持架做了改进，由原先的两体式变为一体式，将两体架改为无铆钉式一体架结构，便于抗冲击，这样能使轴承运转的更加平稳。

Description

一种圆柱滚子轴承
技术领域
本实用新型涉及一种圆柱滚子轴承，特别涉及一种保持架为一体式设计的圆柱滚子轴承。 
背景技术
结合冶金矿山主机用户对轴承使用寿命的要求，矿山机械振动较大，常规圆柱轴承结构（分座与盖，并带铆钉的），工作时常常发生铆钉松动、断裂等现象，需要研制出能够在使用过程中，具有较大额定载荷，较小噪声和较长使用寿命的一种圆柱滚子轴承。 
发明内容
本实用新型针对以上问题上述技术方案的缺陷，本实用新型提供一种具有较大额定载荷，较小噪声和较长使用寿命的一种圆柱滚子轴承。 
为达到以上目的，通过以下技术方案实现的： 
一种圆柱滚子轴承，由内滚道、外滚道、圆柱滚子和保持架组成，保持架为空心圆柱体，且空心圆柱体中心空心为圆形；保持架外壁加工有环形凹槽，且环形凹槽底部加工有矩形通孔；矩形通孔长度与圆柱滚子长度相同，宽度与圆柱滚子直径相同；矩形通孔数量与圆柱滚子数量相同； 
采用上述技术方案的本实用新型，对常规的保持架做了改进，由原先的两体式变为一体式，将两体架改为无铆钉式一体架结构，便于抗冲击，这样能使轴承运转的更加平稳。 
上述说明仅是本实用新型技术方案的概述，为了能够更清楚了解本实用新型的技术手段，而可依照说明书的内容予以实施，并且为了让本实用新型的上述和其他目的、特征和优点能够更明显易懂，以下特举较佳实施例，并配合附图，详细说明如下。 
附图说明
图1为本实用新型剖面结构示意图。 
图2为本实用新型保持架主视结构示意图。 
图3为本实用新型保持架局部剖面示意图。 
具体实施方式
如图1和图2所示的一种圆柱滚子轴承，由内滚道1、外滚道2、圆柱滚子3和保持架4组成；保持架4为空心圆柱体，且空心圆柱体中心空心为圆形；保持架4外壁加工有环形凹槽5，且环形凹槽5底部加工有矩形通孔6如图3所示；矩形通孔6长度与圆柱滚子3长度相同，宽度与圆柱滚子3直径相同；矩形通孔6数量与圆柱滚子3数量相同；圆柱滚子3放置于于矩形通孔6内； 
采用上述结构的本实用新型将保持架4加工为一体式，进而将两体架改为无铆钉式一体架结构，便于抗冲击，这样能使轴承运转的更加平稳。 
以上所述，仅是本实用新型的较佳实施例而已，并非对本实用新型作任何形式上的限制，虽然本实用新型已以较佳实施例揭露如上，然而并非用以限定本实用新型，任何熟悉本专业的技术人员在不脱离本实用新型技术方案范围内，当可利用上诉揭示的技术内容做出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本实用新型技术方案的内容，依据本实用新型的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本实用新型技术方案的范围内。
