“…According to the complicated and heavy geometrical models required during the establishing process of the tooth surface, Maksat developed a novel mathematical model with non-linear equations that were reduced more than those used for the conventional method, making the tooth contact analysis much easier [15,16]. Shaabidov and Xiao investigated the dynamic performance and reliability of a gearbox with time-varying velocity, and variations in the material, strength and size of the abrasive particles, obtaining the mapping rules of the gear pair [17,18]. Jasem and Xie focused on the gear mesh stiffness to validate their proposed gear dynamic model, indicating that the wave face kinematic reducer does not require fulfillment of the conditions for the equality of the center distances [19,20].…”

An atypical face gear pair with complex transmission motion can be used in intermittent reciprocating mechanisms with more precise transmission and a much higher capacity than conventional mechanisms, such as cams and linkages. In this study, we derive a mathematical equation for the complex tooth surface of this gear pair. We indicate the change in root cutting, top sharpening and the effective width of the tooth surface with different parameters. Additionally, we derive the governing equation for the kinematical characteristics of this eccentric curve-face gear pair with a rigid–flexible coupling system, revealing the continuous intermittent contact principle of this gear type with different parameters. Boundary conditions for the gear pair are proposed, demonstrating that the vibration of the gear pair is more obvious, even at a low velocity. In addition, the critical velocity, which mostly ranges from 300 rpm to 400 rpm, is affected by the stiffness of the frames and the parameters of the tooth surfaces. The interval space and interval time of the intermittent contact system are Δd≤0.3 mm and Δt≤5.6×10−4 s, with visible surface sliding on the contact area. It is shown that the contact points are firstly concentrated at the outer part of the tooth surface and that the meshing will break off at the first tooth with the minimum inner radius RGi−min. These theoretical results, which have been verified experimentally, provide theoretical support for further analysis and the better application of this unconventional gear pair.

The work is devoted to increasing the operating life of parts of weaving equipment. The method of accelerated wear tests is considered. Technological approaches for applying a wear-resistant coating to parts of weaving equipment are identified. Coatings from powder materials PG-10N-01 are promising for hardening the friction surfaces of parts of weaving equipment. The operating life of parts with coatings according to the wear resistance criterion is increased up to 15 times concerning the parts with coatings made of TSP-6. Under existing operating conditions, emergency situations due to delamination of the coating are excluded.
