一.深沟球轴承简介

A brief introduction, deep groove ball bearing

深沟球轴承是滚动轴承中最为普通的一种类型.基本型的深沟球轴承由一个外圈,一个内圈.一组钢球和一组保持架构成.深沟球轴承类型有单列和双列两种,单列深沟球轴承类型代号为6,双列深沟球轴承代号为4.其结构简单,使用方便,是生产最普遍,应用最广泛的一类轴承.

Deep groove ball bearing is the most common type of rolling bearing. The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a steel ball and a group of cage. There are two kinds of single and double row deep groove ball bearing type, single row deep groove ball bearing type code is 6, double row deep groove ball bearing code 4. Its structure is simple, easy to use, is the most common production, the most widely used class of bearings.

二.工作原理

Two, working principle

深沟球轴承主要承受径向载荷,也可同时承受径向载荷和轴向载荷.当其仅承受径向载荷时,接触角为零.当深沟球轴承具有较大的径向游隙时,具有角接触轴承的性能,可承受较大的轴向载荷.深沟球轴承的摩擦系数很小,极限转速也很高, 特别是在轴向载荷很大的高速运转工况下,深沟球轴承比推力球轴承更有优越性

Deep groove ball bearings mainly bear radial load, also can bear radial load and axial load. When the radial load is only the contact angle is zero. When the deep groove ball bearings with a larger radial clearance, with angular contact bearing performance, can bear large axial load. Deep groove ball bearing friction coefficient is small, the limit speed is very high, especially under the axial load a lot of high speed operation, deep groove ball bearing thrust ball bearings are more advantages than

三.轴承构造

Three, bearing structure

深沟球轴承结构简单,与别的类型相比易于达到较高的制造精度,所以便于成系列大批量生产,制造成本也较低, 使用极为普遍.深沟球轴承除基本型外, 还有各种变型结构,如:带防尘盖的深沟球轴承,带橡胶密封圈的深沟球轴承,有止动槽的深沟球轴承,有装球缺口的大载荷容量的深沟球轴承,双列深沟球轴承.

Deep groove ball bearing has the advantages of simple structure, and other types of more easily than to high manufacturing precision, so easy to become series of mass production, the manufacturing cost is low, the use is very common. Deep groove ball bearings in addition to the basic type, there are a variety of variant structure, such as: deep groove ball bearings with dust cover, with a rubber sealing ring of deep groove ball bearing, stop deep groove ball bearings, ball gap large load capacity of deep groove ball bearing is installed, double row deep groove ball bearings.
