Abstract

Изобретение относитс  к машиностроению и может быть использовано в соединени х, например вал-ступица, работающих в услови х динамического нагружени . Цель изобретени  - повышение ресурса работы в услови х динамического нагружени . Шпонка состоит из двух продольных брусков пр моугольного поперечного сечени , соединенных дугообразными упругими участками, концы которых установлены в пазах, выполненных на торцах продольных брусков. При передаче крут щего момента дугообразные участки 3,4 деформируютс . Бруски 1,2 сход тс  . За счет этого предотвращаетс  мгновенность передачи крут щего момента от вала к установленной на нем детали, тем самым повышаетс  ресурс работы шпонки. 1 з.п. ф-лы, 4 ил.The invention relates to mechanical engineering and can be used in joints, such as shaft hub, operating under dynamic loading conditions. The purpose of the invention is to increase the service life under dynamic loading conditions. The key consists of two longitudinal bars of rectangular cross section connected by arcuate elastic sections, the ends of which are installed in grooves made on the ends of the longitudinal bars. When transmitting torque, the arcuate portions 3,4 are deformed. Bars 1,2 descent vehicle. Due to this, the instantaneous transmission of torque from the shaft to the part mounted on it is prevented, thereby increasing the life of the key. 1 hp f-ly, 4 ill.
