Изобретение относитс к бурению скважин , а именно к устройствам дл измерени крут щего момента при свинчивании труб.The invention relates to the drilling of wells, namely to devices for measuring the torque moment when screwing pipes.
Известен измеритель осевого усили , преимущественно дл измерени крут щего момента в механизме свинчивани труб с приводом от черв чного вала, который содержит корпус и измерительный блок с чувствительным элементом.An axial force meter is known, advantageously for measuring the torque in a screwing mechanism driven by a worm shaft, which comprises a housing and a measuring unit with a sensing element.
Недостатком устройства вл етс воз- О можность измерени крут щего момента только при свинчивании труб, что не позвол ет определить крут щий момент, возникающий при развинчивании труб.The drawback of the device is the possibility of measuring the torque only when screwing the pipes, which does not allow to determine the torque that occurs when unscrewing the pipes.
Наиболее близким к предлагаемому потехнической сущности вл етс измеритель осевого усили , включающий корпус и измерительный блок с чувствительным элементом в виде диска, жестко соединенного с корпусом.Closest to the proposed technical entity is an axial force meter, comprising a housing and a measuring unit with a sensing element in the form of a disk rigidly connected to the housing.
Недостатком механизма вл етс то, что 20 он не обеспечивает необходимую точность измерений, что не позвол ет использовать его при замере больших крут щих моментов .The disadvantage of the mechanism is that 20 it does not provide the necessary accuracy of measurements, which does not allow using it when measuring large torques.
Цель изобретени - повышение диапазона измерений.The purpose of the invention is to increase the measurement range.
Указанна цель достигаетс тем, что диск чувствительного элемента выполнен со ступицей , жестко св занной с черв чным валом,This goal is achieved by the fact that the sensitive element disk is made with a hub rigidly connected to a worm shaft,
Такое выполнение устройства упрощает конструкцию и повышает точность измерений .This embodiment of the device simplifies the design and improves the accuracy of measurements.
На чертеже изображено устройство, общий вид.The drawing shows the device, the overall appearance.
Устройство состоит из корпуса 1, в котором размещены трубозажимное устройство 2 и черв чна пара, состо ща из черв чного вала 3 и черв чного колеса 4, с которым жестко св зано водило 5. Опорный узел черв ка 3 включает радиальный подшипник 6 и двойной упорный подшипник 7, который размещен в ступице диска 8, вл ющегос чувствительным элементом. Упорный подшипник 7 св зан с черв чным валом 3 и диском 8 упорными гайками 9 и 10. Диск 8, на котором размешена тензодатчики 11, укреплен на фланце 12 корпуса 1. Измерительный блок закрыт крыщкой 13.The device consists of a housing 1, in which a pipe clamping device 2 and a worm gear, consisting of a worm shaft 3 and a worm gear 4, with which the carrier 5 is rigidly connected, are placed. The worm 3 support assembly includes a radial bearing 6 bearing 7, which is located in the hub of the disk 8, which is a sensitive element. The thrust bearing 7 is associated with a worm shaft 3 and a disk 8 with thrust nuts 9 and 10. A disk 8, on which strain gages 11 are placed, is fixed on the flange 12 of the housing 1. The measuring unit is covered by a lid 13.
