Description
Известные устройства дл измерени вертикальных нагрузок на катки гусеничных машин имеют значительные погрешности, так как измер ема нагрузка передаетс на тензометрическую ось неточно из-за непосто нства изгибаюшего момента на тензометрической оси.The known devices for measuring vertical loads on rollers of tracked machines have significant errors, since the measured load is transmitted to the strain gauge axis inaccurately due to the inadequacy of the bending moment on the strain gauge axis.
Предлагаемое усгройство отличаетс тем, что наружна поверхность втулки, предназначенной дл передачи нагрузки от катка к тензометрической оси, образована двум коническими поверхност ми, сопр женными большими основани ми, создаюшими на поверхности втулки гребень, выступаюш;ий над беговой дорожкой гусеницы.The proposed arrangement is characterized in that the outer surface of the sleeve, designed to transfer the load from the roller to the strain gauge axis, is formed by two conical surfaces, conjugated with large bases, creating a ridge on the surface of the sleeve, extending above the track treadmill.
Это позвол ет повысить точность измерени .This allows for improved measurement accuracy.
На чертеже изображена конструктивна схема предлагаемого устройства.The drawing shows a structural diagram of the proposed device.
Устройство состоит из съемной тензометрической оси /, на параллельных лысках которой размеш,ены тензодатчики сопротивлени 2 и втулки 3 дл воспри ти нагрузки и передачи ее от катка 4 гусеницы на тензометрическую ось. Последн выполнена в виде двухопорной балки равного изгибающего момента .The device consists of a removable strain gauge axis /, on parallel flats which is stirred, enens resistance strain gauges 2 and a sleeve 3 to receive the load and transfer it from the track 4 track to the strain gauge axis. The latter is made in the form of a two-support beam of equal bending moment.
на наружной поверхности втулки гребень. Выступаюшими концами тензометрическа ось устанавливаетс в проушины трака гусеницы 5 таким образом, чтобы гребень втулки выступал над уровнем беговой дорожки гусеницы . Благодар конической вершине втулки нагрузка от катка 4 прилагаетс посредине между опорами втулки, что позвол ет повысить точность измерени . Поворачивание осиon the outer surface of the sleeve comb. Protruding ends of the strain gauge axis is installed in the lugs of the track of the caterpillar 5 so that the ridge of the sleeve protrudes above the level of the track of the caterpillar. Due to the conical top of the sleeve, the load from the roller 4 is applied midway between the supports of the sleeve, which allows for improved measurement accuracy. Turning axis
