изобретение относитс к устройствам, преднаначенным дл съема и передачи электрических сигналов от измерительных датчиков, например тензодатчиков, установленных на быстровращающихс детал х , на неподвижные относительно датчиков приборы.The invention relates to devices intended for the removal and transmission of electrical signals from measuring sensors, for example strain gauges mounted on rapidly rotating parts, to devices that are fixed relative to the sensors.

Известен высокооборотный ртутный токосъемник , статор которого выполнен из контактных колец, разделенных изол ционными втулками, заключенными в корпус 1. Недостатком данного устройства вл етс высока трудоемкость изготовлени статора.A high-speed mercury current collector is known, the stator of which is made of contact rings separated by insulating sleeves enclosed in housing 1. The disadvantage of this device is the high labor intensity of stator manufacturing.

Известен также ртутный токосъемник, содержащий ротор с контактными кольцами и статор, состо щий из диэлектрического корпуса, крышки, элементов ее креплени и контактного устройства, причем контакты токосъемника амальгамированы ртутью 2.A mercury current collector is also known, comprising a rotor with contact rings and a stator consisting of a dielectric body, a cover, its fastening elements and a contact device, the contacts of the current collector being amalgamated by mercury 2.

К недостаткам упом нутого токосъемника следует отнести повышенную трудоемкость изготовлени корпуса и контактного устройства статора, вследствие большого количества деталей (корпус, крышка, элементы креплени , шины, болты и т.д.).The disadvantages of the above-mentioned current collector include the increased complexity of manufacturing the housing and the stator contacting device, due to the large number of parts (housing, cover, fasteners, tires, bolts, etc.).

Целью изобретени вл етс снижение трудоемкости изготовлени токосъемника.The aim of the invention is to reduce the laboriousness of manufacturing a current collector.

Указанна цель достигаетс тем, что в высокооборотном ртутном токосъемнике, содержащем ротор с контактными кольцами и статор, контакты которых амальгамированы ртутью, а корпус статора выполнен целиком из диэлектрика, корпус статора выполнен в виде полой цилиндрической трубы, а контакты статора - в виде цилиндрических стержней, причем смежные контакты расположены диаметрально противоположно относительно друг друга против контакт10 ных колец ротора.This goal is achieved by the fact that in a high-speed mercury current collector containing a rotor with slip rings and a stator whose contacts are amalgamated by mercury, and the stator housing is made entirely of dielectric, the stator housing is made in the form of a hollow cylindrical tube, and the stator contacts are in the form of cylindrical rods, The adjacent contacts are located diametrically opposite to each other against the contact rings of the rotor.

На фиг. 1 представлен токосъемник, продольный разрез; на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 shows a current collector, a longitudinal section; in fig. 2 is a section A-A in FIG. one.

Claims

In the case of the stator 1, made in one piece from a dielectric, for example, a PCB, in the form of a hollow cylindrical tube, contacts 2, made in the form of cylindrical rods, are pressed and are diametrically opposite to each other opposite each other against each contact ring 3 of the rotor 4. Between the contacts of the stator and the rotor slip rings contain a local mercury contact 5, and the slip ring is isolated from the rotor by a gasket 6. The current collector works as follows. The electrical signals from the rotating sensors with the help of conductors fall on contact rings 3 mounted on the rotor 4 and insulated from it by a gasket 6, through a local mercury contact 5 reach the contacts 2 of the stator 1. When the rotor 4 rotates, the mercury located on the ring 3 acts centrifugal force, and due to the presence of cohesive forces of mercury with contact 2 and ring 3, shear forces appear that hold the mercury in the gap near contact 2, forming a stable local mercury contact 5. Due to the diametrically opposed You can disposed adjacent contacts 2 of the stator increases the distance between them, reducing the likelihood of closing contacts the stator. Performing the stator housing in the form of a hollow cylindrical tube, and stator contacts in the form of cylindrical rods allows a significant reduction in the labor intensity of high-speed manufacturing. mercury current collector. A high-speed mercury current collector comprising a rotor with slip rings and a stator, the contacts of which are amalgamated by mercury, and the stator housing is made entirely of dielectric, characterized in that, in order to reduce the complexity of manufacturing, the stator housing is made in the form of a hollow cylindrical tube, and the stator contacts - in the form of cylindrical rods, with the adjacent contacts being diametrically opposed relative to each other against the contact rings of the rotor.
