Abstract

The invention provides a double-bowl vibration isolator which comprises a steel pad and an upper bowl rubber pad. A supporting pipe and a lower bowl rubber pad are fixedly installed above the steel pad, the supporting pipe is connected in the lower bowl rubber pad in a sleeving manner, multiple pressure regulating grooves are evenly distributed in the outer surface of the lower bowl rubber pad along a bus, an annular pressure regulating groove is formed below the pressure regulating grooves, an upper bowl steel pad is installed above the upper bowl rubber pad, the upper bowl rubber pad is connected to the outer side of the lower bowl rubber pad in a sleeving manner, through holes used for allowing screws to penetrate are formed in the middle of the upper bowl steel pad and the middle of the steel pad, and an upper bowl pressure regulating groove is formed in the bottom of the upper bowl rubber pad. When the double-bowl vibration isolator is in a free state, a gap exists between the lower surface of the upper bowl steel pad and the supporting pipe, and the size of the gap is not smaller than the axial deformation of a lower bowl seat and an upper bowl in an assembled state. When thedouble-bowl vibration isolator is in a clamping state, the lower surface of the upper bowl steel pad is tightly attached to the supporting pipe. According to the double-bowl vibration isolator, the problems that matching of the vibration performance of rubber vibration isolators mainly depends on material characteristics, the matching difficulty is large, and the matching precision is poor are solved.

Description

technical field [0001] The invention belongs to the technical field of diesel engine electronic control, and in particular relates to a double-bowl vibration isolator. Background technique [0002] With the development of digital technology for diesel engines, the box components such as controllers and monitors continue to increase. Especially on running vehicles or diesel engines, vibration will affect the long-term reliable operation of the controller and seriously restrict the service life of the controller. Therefore, The appearance of the vibration isolator has solved the life problem to a certain extent. However, at present, the matching of the vibration performance of rubber-based vibration isolators mainly depends on the material properties, and the matching is difficult. Contents of the invention [0003] In view of this, the present invention aims to propose a double-bowl vibration isolator, which solves the problems of difficult vibration matching and poor vibr...
