The basic structure of Section Rolling To develop the basis of bearing rolling bearing, and its working principle is based on rolling friction instead of sliding friction, generally by two rings, a set of rolling elements and cage consisting of a highly general, standardization, serialization is the degree high mechanical basic parts. A variety of machinery have different working conditions, on the load bearing capacity, structure and performance, etc. have put forward different requirements. To this end, bearing the need for a wide range of structures. However, the basic structure is the inner ring, outer ring, rolling elements and cage formed. Bearing in various parts in the role are: For radial bearings, inner ring is usually a tight fit with the shaft and running along with the shaft, usually bearing outer ring or shell holes into the transition with the machine, play supporting role. However, in some situations, there are outer operation, the inner fixed play supporting role or inner and outer rings are also functioning. For thrust bearings, and shaft tight and together with the movement of said shaft washer, and bearing or mechanical shell holes into the transition and play supporting role with the said seat. Rolling body (ball, roller or needle) with the bearing cage is usually arranged evenly between the two rings as a rolling motion, its shape, size and number of direct impact on the load bearing capacity and performance. In addition to be able to roll cage separated evenly outside the body, but also from the guide rollers bearing internal rotation and improve the lubricity and so on. Classification Section Rolling 1. Classification by type of bearing structure (1) can bear the load bearing their direction or different nominal contact angle, divided into: 1) ---- bearings are mainly used to bear radial load bearing, its nominal contact angle from 0 to 45. Nominal contact angle according to the different, and divided into: radial contact bearings ---- nominal contact angle of 0 to bearings: Angular contact bearings ---- nominal contact angle greater than 0 to 45 in the bearings. 2) ---- thrust bearing is mainly used for axial load bearing, its nominal contact angle greater than 45 to 90. At different nominal contact angle is divided into: axial contact bearings ---- nominal contact angle 90 of the thrust bearings: Angular contact thrust bearings ---- nominal contact angle greater than 45 but less than 90 of the thrust bearing. (2) The rolling bearing according to the type, divided into: 1) ---- rolling ball bearings for the ball: 2) ---- rolling roller bearings for the roller. Roller bearings roller press type, and divided into: cylindrical roller bearings ---- rolling body is cylindrical roller bearings, cylindrical roller length and the diameter is less than or equal to 3; needle roller bearings --- - rolling body is a needle roller bearings, needle length and diameter ratio greater than 3, but the diameter is less than or equal to 5mm; tapered roller bearings ---- rolling body is tapered roller bearings; self-aligning roller one by one rolling bearing is a spherical roller bearings. (3) bearing aligning their work can be divided into: 1) self-aligning roller bearing is a spherical shape ----, and can adapt to the two roller angular deviation between the axis line and the angular motion of the bearing; 2) non-self-aligning bearing (rigid roller bearing )---- can impedance angle of offset between the axis line of bearings. (4) rolling bearing according to the number of columns, divided into: 1) ---- with a single row bearings rolling bearings; 2) double row bearings ---- rolling with two bearings; 3) multi-row bearings ---- with more than two rolling bearings, such as three, four-row bearings. (5) whether the separation of bearing their part, divided into: 1) ---- separable bearing bearings with separable parts; 2) can not be separated in the final package bearing ---- bearings, the ring can not be separated from any free bearings. (6) bearing their structure and shape (if not filled tank, with or without inner and outer rings and the ring shape, wall structure, or even whether the cage, etc.) can also be divided into a variety of structural types. 2. By rolling bearings according to their diameter size category size, divided into: (1) miniature bearings ---- nominal diameter size range of 26mm below the bearing; (2) Small bearing ---- nominal diameter size range of 28-55mm bearings; (3) small and medium sized bearing ---- nominal diameter size range of 60-115mm bearings; (4) ---- large bearing nominal diameter size range of bearings for the 120-190mm (5) ---- large bearing nominal diameter size range of 200-430mm bearings; (6) ---- large bearing nominal diameter size range of 440mm or more bearings.
