FIELD: mechanical engineering; vibration isolators.
SUBSTANCE: proposed vibration isolator consists of two pneumatic or hydraulic chambers. One chamber is operating one, and the other is additional one. Chamber are separated and are placed in communication through vibration damping member. Said member is made in form of two partitions. Each partition contains ring channel accommodating bearing unit. Exhaust holes are made over circumference of outer race of each bearing unit. Nozzle is laid tangentially to each ring channel. Nozzle of one ring channel is connected with operating chamber, and exhaust holes connect said ring channel with additional chamber. Nozzle of second ring channel is connected with additional chamber, and exhaust holes connect second ring channel with operating chamber.
EFFECT: improved efficiency of vibration isolation owing to provision of optimum dynamic characteristics of vibration damping member.
