An anti-vibration adjustment support

Abstract

An anti-vibration adjustment support, the adjustment support, from top to bottom, are arranged in sequence: a bowl-shaped gasket, a screw sleeve, a fixed nut, a nut seat, a positioning pin, and a fixed plate; the bowl-shaped gasket cover On the top of the screw sleeve; the screw sleeve is tubular, the inner wall of the tube is provided with a right-handed internal thread, the outer wall of the tube is divided into two sections, the lower section is circular, with a left-handed external thread, and the upper section is hexagonal; The pitch of the right-handed internal thread and the left-handed external thread is the same; the fixed nut is a left-handed internal thread, connected with the left-handed external thread of the screw sleeve; the fixed nut is fixedly connected on the nut seat; the nut seat is fixedly connected on the fixed plate. The invention utilizes the adjustment and support function of the adjustment support to meet the needs of the four mounting feet when the diesel engine is installed. Vibration creates looseness.

Description

technical field [0001] The invention relates to a support, in particular to an anti-vibration adjustment support for a marine diesel engine on a test bench, and belongs to the technical field of diesel engine production technology. Background technique [0002] Before leaving the factory, marine diesel engines need to be run-in, debugged and other test items. Therefore, it is necessary to install the diesel engine on the test bench, that is, elastically connect the diesel engine and the load device through an elastic coupling, and then fix the diesel engine mounting feet on the fixed support of the test bench. As we all know, the diesel engine has four independent rigid mounting feet, which are rigidly connected with the diesel engine. In theory, in the height direction, the height of the bottom plane of each mounting foot to the centerline of the crankshaft of the diesel engine is consistent, that is, the four mounting feet The bottom plane of the feet is theoretically on ...

Problems solved by technology

As we all know, the diesel engine has four independent rigid mounting feet, which are rigidly connected with the diesel engine. In theory, in the height direction, the height of the bottom plane of each mounting foot to the centerline of the crankshaft of the diesel engine is the same, that is, the four mounting feet The bottom plane of the feet is theoretically on the same plane. In fact, due to manufacturing errors, positioning errors, assembly errors, etc., the bottom planes of the four mounting feet are not a plane, but there is a slight error, although it does not affect the diesel engine and the load device. connection accuracy, but the diesel engine usually has only three mounting feet supported on the fixed support, and the other foot is suspended in the air, thus causing the center of gravity of the diesel engine to be unstable. During the test run of the diesel engine, vibration and noise will be generated. In severe cases, it will cause The mounting feet are broken. In order to ensure that the four mounting feet of the diesel engine can be effectively supported at the same time, gaskets are usually added under the suspended mounting feet. Since the mounting feet of each diesel engine have different suspended heights and the thickness of the gasket is limited, therefore, This method is difficult to completely eliminate the gap between the mounting feet and the fixed support, so it cannot completely overcome the vibration and noise caused by the installation of the diesel engine
