This paper addresses the issue of difficulties in servicing the brake pipe connectors for passenger cars, the service life of which exceeds 8‒10 years, which is associated with the deteriorated loosening of connectors. The existing ways to loosen the connectors of brake pipes have been investigated, especially those whose dismantling is complicated...

A method of processing the outer and inner conical surfaces.

The possibility of using conventional cutters, in which the super-hard materials Hexanit R acts as the material for the diamond knurling of shaft sections made of steel 10, has been investigated. It is recommended to use damaged replaceable tips with super-hard material as tool blanks, which requires either re-grinding or recycling. The possibility...

We have proposed a technique for obtaining outer profiled surfaces, which is characterized by affordability and low cost of equipment used. The technique is based on that a regular rotating center is fixed in a lathe’s tool holder in a special way. A basic socket head of the required profile is applied as a profile-forming matrix. A tool holder’s r...

During the theoretical calculations of the power level consumed by the mortar mixer drive when mixing constructional mortar components, it is proposed to use the movement resistance specific coefficient. The developed method and a series of researches on an experimental test bench allowed to determine its numerical values when mixing cement-sand, l...

Проведено літературний огляд сучасних джерел енергії, які можливо застосовувати для опалення приватного будинку. Зазначено їх основні переваги та недоліки в умовах енергетичної ситуації, що склалася на даний час. Запропоновано конструкцію дров’яної печі періодичного функціонування, як альтернативного джерела опалення. Із застосуванням оптичного пір...

The object of research is a differential mortar pump with a horizontal pump column, designed for pumping construction mortars of various mobility to the places of their mechanized application to the treated surfaces. To its disadvantages should be attributed insufficiently studied mechanism of formation of return leakage of the mortar, which direct...

We examined methods of manufacturing profile openings on the metal-cutting machines by the rotational broaching method. Based on the generalized results of analysis of the methods for manufacturing profile openings, we proposed a method of rotational broaching. Bits for drilling machines or screwdrivers are used as the tool. Hardness of the bit is...

The research of working pressure of one-piston pump with a combined compensator of pressure pulsations during the operating cycle is carried out. One of the basic gas law in an isothermal process, namely the law of Boyle-Marriott is employed. The law of piston motion which is driven from the crank-connecting rod mechanism (the axis of the crank sha...
