Изобретение относитс к области машиностроени и может быть использовано дл многократной сборки точных узлов, собираеAthix с зазором, а также в приспособлени х дл линейных и угловых измерений.The invention relates to the field of mechanical engineering and can be used for the repeated assembly of precise assemblies, assembling Axix with a gap, as well as in devices for linear and angular measurements.
Известно устройство дл установки и креплени детали типа втулки на валу, содержащее фиксатор, вход ишй в сквозное отверстие втулки и взаимодействующий с валомA device is known for mounting and fastening a sleeve-type part on a shaft, comprising a retainer, an entrance into the through-hole of the sleeve and cooperating with the shaft.
1 Такое устройство не обеспечивает высокой точности базировани по параллельности образующих базовых поверхностей.1 Such a device does not provide high accuracy of the base on the parallelism of the forming base surfaces.
Дл повыщени точности установки втулки по параллельности образующих базовых поверхностей в предлагаемом устройстве втулка выполнена с выемкой, расположенной по всей ее дли.не на внутренней поверхности с диаметрально противоположной стороны от отверсти под фиксатор, ширина и радиус которой наход тс в следующей зависимости от диаметра вала;To increase the accuracy of the installation of the sleeve in parallel with the forming base surfaces in the proposed device, the sleeve is made with a recess located along its entire length on the inner surface with the diametrically opposite side of the retainer hole, the width and radius of which are in the following dependence on the shaft diameter;
,3D- (0,4-0,45)Z),, 3D- (0.4-0.45) Z),
где D - диаметр вала.where D is the diameter of the shaft.
На фиг. 1 изображено предлагаемое устройство , продольный разрез; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 shows section A-A in FIG. one.
Узел состоит из вала 1, на который надеваетс втулка 2, винта 3, прижимающего через сухарь 4 втулку 2 к валу 1. На внутренней поверхности втулки 2 выполнена на всю длину выемка а, щирина которой определ етс по формуле:The assembly consists of the shaft 1, on which the sleeve 2 is put on, the screw 3, which presses the sleeve 2 to the shaft 1 through the cracker 4. On the inner surface of the sleeve 2, there is a recess a full length, the width of which is determined by the formula:
/ 0,3),/ 0,3),
где D - диаметр внутреннего базового отверсти .where D is the diameter of the inner base hole.
Радиус выемки выполн етс в зависимости:The excavation radius is dependent on:
(0,4-0,45) D. (0.4-0.45) D.
Дл сборки узла на вал 1 надевают втулку 2 и винтом 3 креп т ее. При разборке отпускают винт 3. Исход из конкретных условий , во врем сборки возможно как надева-пие втулки 2 на вал 1, так и продевание вала 1 через отверстие втулки 2.To assemble the assembly onto the shaft 1, put the sleeve 2 and fasten it with the screw 3. When disassembling, release the screw 3. Based on the specific conditions, during assembly, it is possible both the sleeve 2 is put on and the shaft 1 is threaded through the hole of the sleeve 2.
Наличие выемки а обеспечивает точное базирование по параллельности образующих базовых поверхностей.The presence of the notch and provides an accurate basis for the parallelism of the forming base surfaces.
