Description
Известны конструкции щеткодержателей, в которых нажим на щетку осуществл етс с немощью давлени воздуха через поршень и жестко св занный с ним шток. Однако в известных конструкци х даже при тщательной подгонке поршн в цилиндре не исключена утечка воздуха через зазор между стенкой цилиндра и поршнем и, кроме того, .из-за попадани щеточной пыли в цилиндр возможны заедани поршн .Designs of brush holders are known in which pressure on the brush is carried out with the infirmity of the air pressure through the piston and the rod rigidly connected with it. However, in well-known structures, even with careful adjustment of the piston in the cylinder, air leakage through the gap between the cylinder wall and the piston does not exclude, and, moreover, due to ingress of brush dust into the cylinder, piston can jam.
В предложенном устройстве дл создани давлени на шток применен расположенный внутри цилиндра резиновый мех или баллон, соединенный с резервуаром с жидкостью.In the proposed device for creating pressure on the rod, a rubber fur or a balloon connected inside the cylinder is connected to the reservoir with a liquid.
На фиг. 1 изображено предлагаемое устройство в продольном разрезе; на фиг. 2 - резиновый баллон.FIG. 1 shows the proposed device in longitudinal section; in fig. 2 - rubber bottle.
Устройство состоит из цилиндра /, резинового баллона 2, штока -i, сочлененного с буфером 4, и щетки 5.The device consists of a cylinder /, a rubber cylinder 2, a stem -i articulated with buffer 4, and a brush 5.
Рабоча среда, например жидкость, из резервуара (на чертеже не показан) по трубке 6 подаетс в резиновый баллон под необходимы.м давлением. Давление рабочей среды через буфер , шток 3 и изолирующую прокл;щку 7 передаетс на щетку 5.The working medium, e.g. liquid, from the reservoir (not shown in the drawing) through pipe 6 is supplied to the rubber container under the necessary pressure. The pressure of the working medium through the buffer, the rod 3 and the insulating section; the jaw 7 is transferred to the brush 5.
Предмет изобретени Subject invention
Устройство дл нажима на щетки электрических машин, выполненное в виде цилиндра с подвижным штоком, передающим давление на щетку, отличающеес - тем, что дл создани давлени на шток применен расположенный внутри цилиндра резиновый мех или баллон, соединенный с резервуаром с жидкостью.A device for pressing the brushes of electric machines, made in the form of a cylinder with a movable rod, transmitting pressure to the brush, characterized in that a rubber fur or cylinder connected to the fluid reservoir is used inside the cylinder to create pressure on the rod.
