The work deals with the problem of using flat belts in internal transport systems. There are many modern solutions for such belts, but to use them in demanding logistics systems, it is necessary to analyze the basic problems associated with coupling in a belt transmission. Then fast movement and transport problems can be solved. All these parameters contribute to the new approach to the belt-pulley coupling model, which was proposed in this paper.

“…For this reason, there is a need for improving or create novelty of the techniques of pulleys production, such as, e.g., additive methods as alternative techniques of producing non-circular pulleys-toothed wheels. The selection of the appropriate manufacturing technique has a significant impact on the geometrical parameters of the wheels as well as the durability and wear of the traction gear [ 5 , 6 ]. As well as in and load transfer technology, transport and control, it’s important to minimize the other errors such as, e.g., roundness error of the pulleys during the manufacturing stage for drive operation.…”

The paper presents the procedure of generating geometrical features on the contours of non-circular pulleys through the selection of materials and technological parameters for easy and efficient production of these parts. Based on the models designed in the computer aided design (CAD) system, several prototype non-standard pulleys were made, which were assessed for functional characteristics and correct operation of non-linear gears. The effect of additive technology on the geometric specification of non-circular pulleys was also assessed. The results showed that thanks to the use of additive methods, the need for costly manufacturing of such wheels with subtractive methods was eliminated. Additionally, it is not necessary to design specialized cutting tools or to use conventional or numerically controlled machine tools to manufacture these wheels. The test results showed that in case of selective laser sintering (SLS) the highest accuracy of mapping (0.01 mm) of geometrical features of the surface was obtained. This result is confirmed by the assessment of the morphology of the surface of the teeth of gears made with this technique, characterized by a uniform structure of the working surface of the wheel while maintaining a high tolerance of the outer profile of gear for selective laser sintering at the level of ±0.03 mm. Research has shown that most of the additive methods used to manufacture non-circular pulleys meet the required geometrical features and due to the short production time of these pulleys, these methods also facilitate quick verification of the designed pulley geometry.

“…While many studies, e.g., [5][6][7][8], on geometric measurement have succeeded in enhancing the accuracy of geometric specification, gear manufacturing, or wear evaluation, it is still inevitable to admit the existence of geometric errors in gears induced by diverse uncertain factors. Uncertainty quantification (UQ) measures the possible uncertainties and estimates their relations with one another or the effects on the entire system.…”

Statistical Analysis for Transmission Error of Gear System with Mechanical and Thermal Deformation Uncertainties

We establish a robust algorithm to analyze the influence of system uncertainties on the transmission error of a spur gear pair under 2D simplification. The algorithm provides a way of generating smooth cutter profiles with machining uncertainties and measuring the thermal deformation through the uncertainties in material properties. Then, it produces realizations of gear tooth profiles based on the analytical method for accuracy and computational efficiency. Numerical investigations show the statistical analysis on the tooth contact analysis by comparing steel and plastic gears. It is worthwhile remarking that the plastic gear is susceptible to the geometric error caused by thermal deformation. Moreover, although the impact of thermal deformation on steel gear may seem slim, it can have a noticeable influence when it exists with mechanical uncertainties together.
