Tapered Roller bearings are
radial thrust rolling bearings with tapered roller. There are two kinds of cone
angle and big cone angle .Small cone angle mainly bear radial direction load
primarily radial and axial loads, often used in pairs, reverse installation,
inner and outer ring can be installed separately, in installation using radial
and axial clearance can be adjusted; Big cone angle mainly bear axial load
primarily of axial and radial load, is generally not used to bear alone the
pure axial load, as to the pair (end with the same relative installation) can
be used to carry pure radial load.
Tapered roller bearings are
widely used in automobile, rolling mill, mining, metallurgy, plastic machinery
and other industries.

The reducer is an independent closed mechanical transmission between the prime mover and the working machine. It is used to reduce the prime mover speed or increase the torque to meet the needs of the working machine. Under the premise of meeting the needs, the reducer design should pursue a small volume. Optimized targets such as small size, light weight, low cost and convenient lubrication. In order to choose the correct optimization method, it should be understood which factors are related to the volume and size of the reducer, which are the main factors, and what are the characteristics of the relationship between them.
2 The size and size of the reducer The size and size of the reducer usually refers to its external volume and size. Its size is mainly determined by the space occupied by its internal gear system. Therefore, when optimizing the design, the peripheral volume of the gear system can be optimized. And size instead of the size and size of the reducer, see the calculation diagram.
The dimensions of the three directions in the periphery of the gear system are respectively //, ', 圪, the total transmission ratio, the idle speed ratio, the low speed ratio, and the transmission ratio are 1 "1, 142, meaning, respectively. Simple, the tooth width coefficient of the idle speed and the low speed grade is equal to the low speed active gear tooth number Z3 is equal to the high speed active gear tooth number Zl, and the constant 4 is ignored, then the 2.2 volume index is set to the gear system peripheral volume parameter F, and take 2.3 The comprehensive index takes the sum of the peripheral volume and size of the gear system as the comprehensive index of the reducer, and is expressed by /, then 3 main constraints 3.1 The allowable indexing circle diameter of the strength conditional pinion, see the calculation method.
