The article considers the ratio of forces in belt drives, proposes a calculation scheme for the forces of a flat-belt transmission [FBR], and calculates and analyzes the effect of changing the engagement angle and load on the friction coefficient. Belt drives refer to mechanical friction transmissions with a flexible connection and are used if it is necessary to transfer the load between shafts located at considerable distances. The influence of a change in the coefficient of friction of the belt on the power parameters of the transmission is considered.
The load is given in the form of a torque, which is transmitted to the belts by the circumferential force, the tension of the leading branch increases the circumferential force, and that of the driven branch decreases. Power graphs were built, and the analysis shows that the growth of α hurts the friction coefficient f. The curves have their own regularity with the value of the approximation R2. The influence of the change in the angle of engagement a on the coefficient of friction f with a change in load in the form of belt tensions F1 and F2 or F1 − F2 = Ft is considered. Combining these components, it will be possible to calculate and select rational parameters of belt drives; the maximum increase in the friction coefficient, considering the loads on the shaft and supports, allows transmitting torque with a relatively smaller angle α.
