Problems solved by technology

However if figure 1 As shown, the transmission structure is basically an axisymmetric structure, but in practical applications, the transmission structure of the transmission belt is mostly an asymmetric structure. The asymmetric structure makes the force on the transmission belt on both sides of the driving wheel uneven, and its maximum tangential Force F u It cannot be directly corrected by the coefficient 1 / 2
Therefore, for the transmission structure of the transmission belt in practical applications, if the traditional load calculation method is still used for calculation, a large calculation deviation will be formed, which will affect the detection accuracy of the service strength of the transmission belt based on the fatigue load

Abstract

The embodiment of the invention provides a force calculation method and device for a driving belt in a driving component with an asymmetrical structure. The force calculation method includes the following steps that actual pre-tightening force of the driving belt is detected; according to the maximum tangential force and actual pre-tightening force of the driving belt and a correction coefficientdetermined through finite element simulation analysis, the actual loose edge force and / or the actual tight edge force of the driving belt are / is calculated. According to the method and the device, thedriving-belt load calculation is corrected, the fatigue load of the driving belt can be more accurately calculated, a belt pulley support structure in a fan is thus more accurately evaluated, and themethod and the device have certain referential significance in the strength evaluation of a similar belt driving structure in the engineering practice.

Description

technical field [0001] The invention relates to the field of belt drive fatigue analysis, in particular to a force calculation method and device for a drive belt in an asymmetric structure drive assembly. Background technique [0002] The traditional calculation method of belt load is based on such as figure 1 Theoretical formulas are derived for the belt drive structure shown. The traditional theoretical formula F zt =F v +F u / 2 is widely used in load analysis of various transmission structures. However if figure 1 As shown, the transmission structure is basically an axisymmetric structure, but in practical applications, the transmission structure of the transmission belt is mostly an asymmetric structure. The asymmetric structure makes the force on the transmission belt on both sides of the driving wheel uneven, and its maximum tangential Force F u It cannot be corrected directly by the coefficient 1 / 2. Therefore, for the transmission structure of the transmission...
