Rolling bearing drawing

An overview of the shaft bearing called bearing, bearing in accordance with the different grinding quality at work, can be divided into two categories, the rolling bearing and sliding bearing. Types of rolling bearing, the tectonic pattern, size and drawing have been standardized, thus, it is a kind of standard parts. The structure of the rolling bearings of rolling bearing varieties more, but its structure is roughly same, as shown in the figure below deep groove ball bearings, cylindrical roller bearings, thrust ball bearing structure. The figure is visible, they are all made by outer ring, inner ring, rolling body and adhere to the frame of four local. Among them, the shape of the roller with common ball, cylinder and cone, etc. Usually, the rolling bearing's outer ring device is fixed in the base hole, inner ring is in a rotating shaft and the shaft, and rolling body, the outer ring raceway between rolling, rolling friction. The classification of the rolling bearing roller bearing according to the condition of stress can be divided into three categories: ( 1) The centripetal ball bearings, mainly take radial load. （ 2) Thrust bearing, the main axial load. （ 3) Angular contact bearings, can accept the radial and axial load at the same time. Code rolling bearings of rolling bearings is a group of digits represent bearing structure, type and diameter of code rule expressed in seven digits, commonly used is four digits, the last two figures show that the inner diameter of the bearing number; Said the third digit bearing diameter series, that is, in the inner phase at the same time, there are a variety of different diameter, can consult relevant specification; The fourth number said bearing type, such as: '0' said centripetal ball bearings, '8' said flat thrust ball bearings. Right up 1, 2 digits ( Inner code) 00 02, 03 04 ~ 99 01 diameter values ( mm) 10 to 12 15 to 17 code value multiplied by five is the inner diameter of the rolling bearing rules common way of rolling bearing, the symbol and logo
