Description

Изобретение относитс  к машиностроению . Известно устройство дл  индикации усили  зат жки резьбового элемента , содержащее пружину и втулку , надетые на резьбовой стержень и зат нутые гайкой. Усилие зат жки определ етс  жесткостью пружины и в сотой втулки 1. Недостатками данного известного устройства  вл ютс  необходимость применени  втулки определенных размеров дл  каждого заданного момента и невозможность визуального Контрол  величины усили  зат жки. Известно также устройство дл  ин дикации усили  зат жки резьбового элемента, например винта, содержащее втулку, имеющую боковую и донну стенки и свободно обхватывающую головку резьбового элемента, и пружину , расположенную между головкой ви та и зсоедин емой. деталью 2 . Уси лие зат жки определ етс  жесткостью пружины и величиной ее деформации, выраженной степенью осевого смещени  головки винта относительно втул ки. Недостатком  вл етс  неудобство его эксплуатации, так как опора пружины на соедин емую деталь несколько затрудн ет монтаж винта и снижает точность индикации, завис щей в какой-то мере от степени обработки и твердости соедин емой детали и поэтому требует проведени  дополнительной тарировки при каждом соединении новых деталей. Дл  повышени  удобства эксплуатации и точности индикации пружина расположена между опорным торцом резьбового элемента и донной стенкой соосной втулки и на боковой поверхности резьбового элемента нанесена шкала усили  зат жки. Кроме того, на наружной опорной поверхности донной стенки втулки выполнена насечка, исключающа  проворачивание втулки относительно соедин емой детали при монтаже. На чертеже изображено предлагаемое устройство. Оно состоит из втулки 1, имеющей донную стенку 2 и боковую стенку 3, свободно обхватывающуюкорпус резьбового элемента, например гайки 4. одорным торцом резьбового элемента . (гайки) 4 и донной стенкой 2 втулки 1 расположена пружина 5, результаты Тарировки которой нанесены в виде шкалы 6 на боковой стенке резьбового элемента (гайки).The invention relates to mechanical engineering. A device for indicating the tightening force of a threaded member is known, which comprises a spring and a sleeve, mounted on a threaded rod and tightened with a nut. The tightening force is determined by the stiffness of the spring and in the hundredth sleeve 1. The disadvantages of this known device are the need to use a sleeve of certain sizes for each given moment and the impossibility of visual control of the amount of tightening force. It is also known a device for indicating the tightening force of a threaded element, for example, a screw, comprising a sleeve having side and bottom walls and a free engaging head of the threaded element, and a spring located between the head of the screw and the coupling. detail 2. The tightening force is determined by the spring stiffness and the magnitude of its deformation, expressed by the degree of axial displacement of the screw head relative to the sleeve. The disadvantage is the inconvenience of its operation, since the spring support on the part being connected makes it difficult to mount the screw and reduces the accuracy of the display, depending in some measure on the degree of processing and the hardness of the part being connected and therefore requires additional calibration details. To increase the convenience of operation and the accuracy of the indication, the spring is located between the supporting end of the threaded element and the bottom wall of the coaxial sleeve and a pulling force scale is applied on the side surface of the threaded element. In addition, a notch is made on the outer bearing surface of the bottom wall of the sleeve, eliminating the turning of the sleeve relative to the part being joined during installation. The drawing shows the proposed device. It consists of a sleeve 1, having a bottom wall 2 and a side wall 3, loosely enclosing the body of the threaded element, for example, the nut 4. with an odd face of the threaded element. (nuts) 4 and the bottom wall 2 of the sleeve 1 is a spring 5, the results of the calibration of which are applied in the form of a scale 6 on the side wall of the threaded element (nut).
