Abstract

In vibration control equipment (1) constituted by inserting the outer tube (20) of a pair of damping rubbers (2A, 2B) into the opening (30) of a bracket member (3), clamping the pair of damping rubbers (2A, 2B) by means of plate members (4A, 4B), tightening a fastening member (5) for coupling the plate members (4A, 4B), and then compressing the rubber elastic bodies (22) of the damping rubbers (2A, 2B) in the axial direction, outside diameter of the outer tube (20) before tightening the fastening member (5) is smaller than the inside diameter of the fixing hole (30), the rubber elastic bodies(22) are compression deformed by tightening the fastening member (5) and thus a bracket member (3) is clamped by means of upper and lower flanges (23), at least one of the rubber elastic bodies (22) is provided with mold cavity portions (26A, 26B) and at least one of the pair of outer tubes (20) is provided with a portion (24) for determining the circumferential position of the pair of damping rubbers (2A, 2B) relative to the bracket member (3). According to the invention, assembling work is facilitated by arranging the mold cavity portions in accordance with the direction of vibration and the production cost can be reduced.

Description

technical field

[0001] The present invention relates to an anti-vibration device used as a cabin support, engine support, etc. of agricultural machinery and construction machinery.

[0002] this application claims priority based on Japanese Patent Application No. 2007-095292 for which it applied in Japan on March 30, 2007, The content is used here. Background technique

[0003] Generally, when a vibration generating body such as an engine is mounted on a vibration receiving body such as a body, a vibration isolator for preventing or suppressing transmission of vibration from the vibration generating body to the vibration receiving body is installed between the vibration generating body and the vibration receiving body. As this anti-vibration device, there is a sandwich type anti-vibration device constituted by a structure in which a pair of anti-vibration rubbers are sandwiched from both sides by plate members. The anti-vibration rubber is composed of a substantially cylind...
