轴承基本知识大全

                      Basic Knowledge of Bearing

 

机械类的知识复杂繁多,小小的一个零件都会有很大的功能和很多的分类。比如,轴承。对常接触机械的人们来说,都知道轴承的作用是不可小觑的。可是对于不了解轴承的人来说,关于轴承的有关知识和功用,依旧是一头雾水。下面小编就简单的为大家介绍一下轴承的基本知识信息吧。

The knowledge of mechanism is complex, and many small parts will have a great function and a lot of classification. For example, bearings. For people contacting machinery usually, the role of bearings is not to be underestimated. But for those who do not understand the bearings, the knowledge and function of bearings, is still confusing. In the following, I will introduce you the basic knowledge of bearing.

什么是轴承

What is bearing

相对于大机械而言,轴承是一个很小的零部件,但是却起到了举足轻重的作用。

而它主要是在机械传动过程中起固定和减少载荷摩擦系数的零部件。当其它机件在轴上彼此产生相对运动时,轴承可以用来降低动力传递过程中的摩擦系数和保持轴中心位置的固定。按运动元件摩擦性质的不同,轴承可分为滚动轴承和滑动轴承。

The bearing is a small part comparing with a larger machine, but it plays a decisive role.

And it is mainly used in the mechanical transmission process to reduce the friction coefficient of the load components. Bearings can be used to reduce the coefficient of friction during power transmission and maintain the centering of the shaft as other parts move relative to each other on the shaft. According to the different friction properties of moving parts, the bearings can be divided into rolling bearings and sliding bearings.

 

轴承的类型

Types of Bearing

根据轴承的功能、设计和作用的不同,轴承的类型很多,大体包括:滚针轴承、调心球轴承、深沟球轴承、 调心滚子轴承、推力轴承、带座轴承、关节轴承、组合轴承、轧机轴承等。不同的轴承都有不同的功用,在不同的机械设备中都起到了不可小觑的作用。

According to the function, design, and role of bearings, the types of bearings generally include: needle roller bearings, self-aligning ball bearings, deep groove ball bearings, spherical roller bearings, thrust bearings, with bearings, bearings, combination Bearings, mill bearings and so on. Different bearings have different functions, and play significant roles in different machinery and equipment.

轴承的代号

Bearing code

一个完整的轴承代号是由基本代号加上一个或多个补充代号组成。基本代号是用来表示轴承的类型、轴承的基本设计、轴承的外形尺寸。补充代号是指轴承的部件、与基本设计有不同结构或有其它特性的变型。

0 双列角接触球轴承 

1 调心球轴承

2 调心滚子轴承、推力调心滚子轴承

3 圆锥滚子轴承

4 双列深沟球轴承

5 推力球轴承

6 深沟球轴承

7 角接触球轴承

A complete bearing code is composed of the basic code plus one or more supplementary codes. The basic code is used to indicate the type of bearing, bearing the basic design, bearing dimensions. Supplementary code refers to the bearing components, and the basic design has a different structure or other characteristics of the variant.
