Tapered roller bearing force analysis

Tapered roller bearing force analysis - 2019 11 - 23 tapered roller bearing is suitable for the bear radial load, one-way axial load and radial and axial loads. Tapered roller bearing axial load capacity depends on the contact Angle & alpha; Bearings, that is, their point of view, contact Angle & alpha; Is bigger, the greater the axial load capacity. General Angle error is not permitted in tapered roller bearing, but the surface of the roller and raceway after special design can be allowed to have 2 & prime; ~ 4 '; The Angle error. Single row circular cone roller bearings can withstand axial load in one direction, and can limit shaft relative bearing the axial displacement of a direction. Even under the effect of pure radial load, tapered roller bearing internal also can produce additional axial force component, at this point, the need to have a the same amount of reverse reaction to the phase equilibrium. Usually adopts two same structure in the two bearing of single row tapered roller bearing face to face or back to back the relative bearing in order to guarantee a good running condition, tapered roller bearings, like other ball bearings and roller bearings, must exert a certain amount of minimum load, especially for high speed and high acceleration, or there are frequent changes in load direction under the conditions of work. Because, these conditions, roller and cage inertial force and friction within the lubricant to the bearing has a harmful effect on the rolling, rotating accuracy and between roller and raceway is likely to produce harmful to the bearings of the sliding motion. Tapered roller bearing the required minimum load estimation of Fmin can use the following formula: Fmin = 0. 02 C, type C in the basic dynamic load rating, in the condition of low temperature start or lubricant viscosity is very high, the minimum load may require more. Typically, bearing the weight of the thing itself with bearing on the load, has been more than the required minimum load. If have not yet reached the minimum load, the bearing must impose additional radial load, such as the bearing axial pre-tightening, to meet the requirements of minimum load. The use of each product, our most concern is the core of this type of product value and affect the core value of the various factors. For tapered roller bearing, its use efficiency under the influence of the stress distribution, so for the taper roller bearing force analysis is very important, not only is this user should master the knowledge, at the same time it also may be a merchant promotion heart way of this kind of product. To sum up, as editor of tapered roller bearing force do a simple analysis, different working conditions of the tapered roller the uniformity of its force, the characteristics of the work force and the force of scattered points are different, therefore, need professional engineer to design or customized tailored selection. （ Source: wafangdian bearing)
