Innovative Rotor Casing And Leveling Apron For Combined Tillage Machine, A.A. Akhmetov, L.B. Muratov
Innovative Rotor Casing And Leveling Apron For Combined Tillage Machine, A.A. Akhmetov, L.B. Muratov
Irrigation and Melioration
Investigations of the design of a combined machine equipped with an innovative casing and a leveler apron are presented, and the parameters of the leveler apron are substantiated. It was experimentally established that when the height of the drawing prism is exceeded by more than 200 mm, due to the falling of the crumbling part of the soil onto the rotor, the soil is thrown forward in the direction of the machine. Therefore, to eliminate soil waste, it is necessary either to reduce the height of the drag prism, or to increase the distance between the rotor and the leveling …

The parameters of the ridge former and apron-leveler of this machine have been substantiated. The rational values of the parameters of the comb-former are: length 600 mm, width of the entrance edge 680 mm, height of the blade 160 mm, length of the side edge of the blade 178 mm. The rational values of the working length and height of the leveling apron are 220 mm and 200 …
Asynchronous Phase Rotor Generators For Power Planes Operating Parallel With A Network, Sharafiddin Kamaliddinovich Alimhodzhaev, Odil Umirzakovich Zakhidov, Mirzohid Hurramovich Taniev
Asynchronous Phase Rotor Generators For Power Planes Operating Parallel With A Network, Sharafiddin Kamaliddinovich Alimhodzhaev, Odil Umirzakovich Zakhidov, Mirzohid Hurramovich Taniev
Journal of Tashkent Institute of Railway Engineers
The article presents the results of studies of asynchronous generators of wind power plants and small hydroelectric power stations operating in parallel with the electric network. The parameters of the equivalent circuit are specified, on the basis of which the analytical dependence of the electromagnetic moment of the generator is found. It is proposed to take into account the revealed features of the mechanical characteristics of the generators that differ from the characteristics determined by the generally accepted analytical method
Comparative Analysis Of Functional Diagnostic Methods Of Traction Asynchronous Motors, Zhavkharbek Sulton Ugli Fayzullaev
Comparative Analysis Of Functional Diagnostic Methods Of Traction Asynchronous Motors, Zhavkharbek Sulton Ugli Fayzullaev
Journal of Tashkent Institute of Railway Engineers
The article provides a comparative analysis of the methods of functional diagnostics of traction induction motors and justifies that of them the most promising are thermal, electric, vibroacoustic and magnetic methods. To obtain the most reliable information in diagnosing the technical condition of traction induction motors, it is recommended that the methods considered be used in conjunction with the simultaneous improvement of their technical means.

Analysis Of Methods For Determining The Resistance Of Differential Scattering Of Synchronous Machines, Taking Into Account The Saturation Of The Magnetic Circuit, А.K. Halbutaeva
Journal of Tashkent Institute of Railway Engineers
The article presents the results of the analysis of published scientific papers, in which one or another method of calculating the resistance of differential scattering of synchronous machines, taking into account the non-linearity of saturation of the magnetic core, is adopted. It is noted that most of these works are performed using the superposition method, intended only for linear systems.
