“…It is well known that the ball hinge clearance can affect the robot and parallel mechanism accuracy [14]. In the movement process, the direction and value of the clearance have a large randomness, and thus there has been no appropriate method to compensate for the ball hinge clearance error until now.…”

“…Pfister developed a novel fibre optic laser Doppler position sensor for single-blade tip clearance measurements [13]. There are other scholars who developed a monitoring system in accordance with the clearance value and the angle of rotation of the lever-hinge mechanism by using capacitive sensors [14]. The vast majority of research is mainly directed at the effect of a joint with clearance and establishing dynamic models based on clearance.…”

Precision ball hinges are widely applied in parallel mechanisms, robotics, and other areas, but their rotation orientation and angle cannot be obtained during passive motion. The simultaneous clearance error in a precision ball hinge’s motion also can not be determined. In this paper we propose an intelligent ball hinge (IBH) that can detect the rotation angle and moving clearance, based on our previous research results. The measurement model was optimized to promote measurement accuracy and resolution, and an optimal design for the IBH’s structure was determined. The experimental data showed that the measurement accuracy and resolution of the modified scheme were improved. Within ±10° and ± 20°, the average errors of the uniaxial measurements were 0.29° and 0.42°, respectively. The resolution of the measurements was 15″. The source of the measurement errors was analyzed through theory and experimental data and several key error sources were determined. A point capacitance model for measuring the clearance error is proposed, which is useful not only in compensating for the angle measurement error but also in realizing the motion clearance of an IBH in real-time.

Abstract.In the article results of researches of brake devices of lifting machines UD of joint-stock company "ArcelorMittal Temirtau" are resulted. Defects were revealed as a result of the examination. A method and device for the unconditional control of defects and technical condition of the hinged joints of brake devices is developed in terms of the gap size and the angle of rotation between the links of the kinematic pairs "Widget-finger". For the monitoring of gaps, capacitive sensors are installed, mounted on hinged joints. It is substantiated that with the use of capacitive sensors it is possible to control the gaps in the hinged joints in real time. A device has been developed that makes it possible to estimate the magnitude of the gap at several points of the kinematic chain of the mechanism simultaneously.

“…These washing machines are quite energy-intensive and metalconsuming, which implies high operating costs for the food industry. For this reason, the design and launch of innovative and highly efficient washing machines in the canning industry is a sufficient reserve that allows to sufficiently reduce energy and material costs, as well as the cost of the canning process [6][7][8][9].…”

Nowadays industry uses special washing machines to wash the outer surface of cans, which can be jet, submersible and combined-type. These washing machines are quite energy-intensive and metal-consuming. A washing machine was designed in Mari State University, in which the objects cleaned gain eccentric motion and bubbling is created from the side of cylindrical cans. In order to identify the dependence of the cleaning quality on liquid activation using the air bubbling method, a number of factor-at-a-time experiments with a three-fold repeatability were performed at the outside of the washed objects. Special theoretical calculations were carried out to identify the limits of the drive wheel speed values aimed at studying kinematic parameters. The type of hyperbolic dependence of the wheel diameter on its rotation frequency is also determined.
