“…profiling or lace cutting. Nowadays, in cylindrical worms used in worm gears, except helical straight or cone-shaped surfaces, there are also used concave surfaces with an arched nominal profile of the thread or with an arched nominal profile of the tool for tooth machining [1,2].At the same time, due to technological reasons, the arched nominal profile can be tangential to the main cylinder of the worm in the normal or axial cross-section.Also in the worms used in polymer processing machines, a very important issue is the shape of the profile of the side surfaces of the threads, which affects the quality of mixing and homogenization of plastic components [3,4].…”

Despite the fact that worm gears have been known for millennia, they are still used and they are constantly improved and developed. The goal is to obtain a gear that is not wearing out under the assumed operating conditions. That is why such an important issue is the ability to make worms with a defined profile as well as with a certain accuracy. This directly affects the durability of the worm gear. Comparing worm gears with concave-convex surfaces with conventional cooperation surfaces worm gears, they are characterized by: more favorable change in the distribution of Hertz pressure, change in the course of the contact line between the cooperating surfaces and an increase in the thickness of the worm wheel tooth at the base. In this way, improved power transmission and lubrication properties can be expected, what consequently results in less energy loss and less wear. The article presents the method of forming helical surfaces with a circular concave axial profile by the point method and the developed code generation program for controlling a universal multi-axis CNC machine tool.

“…The use of V-belts in belt transmissions dates back to the beginning of the 20th century, however, in the last dozen or so years, thanks to intensive development of the chemical industry, many new materials used in the production of drive and transport belts have been developed [1][2][3]. The development of belt transmissions concerns new materials [4][5][6][7], geometric forms of belts [8][9], pulleys and intermediary drive transmission elements [10][11][12][13][14][15]. The source of incorrect operation of belt transmissions can be inaccuracies in the assembly of machines and devices [16,17], unbalance and shape of elements in rotary motion [18][19][20][21], wear and tear of elements, change of belt transmission temperature [22,23].…”

The continuous increase in the use of the transmissions with V-belt, the introduction of new materials for the production of belts and the development of new manufacturing techniques have become the reason for undertaking research works on the possibilities of increasing the load capacity and durability of belts as well as reducing their influence on the environment. It is important to know the latest mechanical and rheological characteristics of the belts in terms of their strength characteristics and fulfilment of the conditions for the correct operation of the transmission. The results of these works will make it possible to determine the scope of applicability of these belts in propulsion and transport technology as well as to develop new geometrical forms of pulleys and V-belts.

“…The aim is to achieve a suitable combination of the required rheological and physical-mechanical properties of rubber compounds and vulcanizates in order to ensure the correct function and the necessary operating life of a particular product in connection with its application. The current development of polymeric systems is intensively focused on the application of various types of alternative fillers, especially in connection with the greening and economization of the production of various polymeric components [4][5][6]. The emphasis is placed on the possibility of using wastes from other industries as alternative fillers, in properties of the final products for their specific industrial applications.…”

order to obtain an elastomeric material with specific properties. The addition of an alternative filler to the rubber compound results in a completely new type of composite elastomeric material, in which an improvement in several important quality parameters can be observed simultaneously. The resulting products containing alternative fillers show, e.g. a positive increase in the values of rebound resilience and a decrease in the values of rolling resistance, while maintaining the optimal values of hardness [6][7][8].The continuous improvement of the final product quality with the simultaneous elimination of waste from the technological process and the reduction of production costs are in the best interests of producers [9]. Such a suitable combination of specific properties is usually difficult to achieve using only conventional types of fillers such as carbon black or silica. A specific combination of quality parameters can be achieved using the new types of alternative additives based on selected kinds of waste from industrial productions. Especially by application procedures of suitable inorganic materials into organic polymers, a significant improvement of physical and mechanical properties of elastomers can be achieved, specifically of hardness, tensile straight, modulus, but also rebound resilience and rolling resistance, which are very important parameters for industrial applications [10]. Composite materials with polymeric matrix prepared this way show generally better properties than pure and homogeneous materials. The positive changes have been observed at low concentrations of the inorganic components in polymers [10,11].This work is focused on the development and study of new types of elastomeric systems using alternative fillers based on selected industrial wastes, in order to achieve the required
