Description

ГR

Изобретение относитс  к машиностроению и может быть использовано дл  охлаждени  подшигагака , установленного на вращающемс  валу, в шпиндельных узлах металлорежущих станков, в роторах турбин и электрических мащин и т.д.The invention relates to mechanical engineering and can be used for cooling a knuckle mounted on a rotating shaft, in spindle assemblies of machine tools, in rotors of turbines and electric machines, etc.

Известно устройство дл  охлаждени  подщинника , установленного на вращающемс  валу. Оно СОСТОИТ из приспособлени  дл  ввода охлаждающего агента, неподвижной питающей трубки с уплотнени ми, отдел ющими ее от вращающегос  вала, системы извилистых каналов внутри вала, по которым прокачиваетс  охлаждающий агент, и распределительного устройства, обеспечивающего циркул щ1ю охлаждающего агента по внутренним каналам.A device for cooling a pad mounted on a rotatable shaft is known. It consists of a device for introducing a cooling agent, a fixed feed tube with seals separating it from the rotating shaft, a system of winding channels inside the shaft through which the cooling agent is pumped, and a switchgear that circulates the cooling agent through the internal channels.

Однако ЭТО устройство конструктивно сложно дл  массового производства, практически невозможно ВЫПОЛНИТЬ его, не вызвав дебаланс вала, и, ХОТЯ ЭТОТ дебаланс в некоторых случа х можно устранить специальной балансировкой, нельз  обеспечить течение охлаждающего агента по ИЗВИЛИСТЫМ каналам по периферии вала так, чтобы балансировка не нарушалась, что исключает ВОЗМОЖНОСТЬ применени  этого устройства вHowever, an IT device is structurally difficult for mass production, it is almost impossible to EXECUTE it without causing an unbalance of the shaft, and, although this unbalance can be eliminated by special balancing in some cases, it is impossible to ensure the flow of cooling agent along the IZILISTY channels along the shaft periphery so that the balancing is not disturbed. , which eliminates the possibility of using this device in

Скоростных прецизионных узлах вращени . Кроме ТОГО, конструкци  требует наличи  уплотнений как на входе, так и на выходе охлаждающего агента. В ней охлаждающа  жидкость вводитс  по специальной питающей трубке с торца вала в центральное отверстие вдоль оси вала, проходит по системе извилистых каналов, расположенных внутри вала и выходит с того же торца вала.High-speed precision knots. In addition to this, the design requires seals both at the inlet and at the outlet of the cooling agent. In it, the cooling fluid is introduced through a special feeding tube from the shaft end into the central hole along the shaft axis, passes through a system of tortuous channels located inside the shaft and exits from the same shaft end.

Цель изобретени  - повыщение эффективности охлаждени  при высоких скорост х вращени  вала.The purpose of the invention is to increase the cooling efficiency at high shaft rotation speeds.

Это достигаетс  тем, что в предлагаемом устройстве узел ввода охлаждающего агента выполнен в виде сопла, а охлаждаемые полости вала выполнены в виде центрального глухого отверсти , проход щего -по оси вала, на дне которого выполнен отражатель, при этом сопло размещено по центру глухого отверсти  вала.This is achieved by the fact that in the proposed device the coolant injection unit is designed as a nozzle, and the cooled cavities of the shaft are designed as a central blind hole passing along the axis of the shaft at the bottom of which a reflector is made, while the nozzle is located at the center of the blind hole of the shaft .

На чертеже представлено предлагаемое устройство , общий вид, разрез.The drawing shows the proposed device, General view, the cut.

Вдоль оси вала 1 выполнено центральное глухое отверстие 2, причем зто отверстие может быть и коническим, расщир ющимс  кAlong the axis of the shaft 1, a central blind hole 2 is made, and this hole may be conical, extending to
