Oil bath engine coupling device and engine test device

Abstract

This application relates to an oil-bath engine coupling device and an engine test device. The oil-bath engine coupling device includes a shaft structure and a bearing structure. The shaft structure includes a shaft body for connecting the engine to a dynamometer; the bearing structure It includes the first bearing and the second bearing respectively arranged at both ends of the shaft body, and the bearing oil bath structure. The bearing oil bath structure includes an oil collecting shell arranged under the shaft body and the bearing structure, and an oil pumping structure arranged on the shaft body , an oil inlet pipe connected between the oil collecting housing and the oil pumping structure, a first oil outlet pipe connecting the oil pumping structure and the first bearing, and a second oil outlet pipe connecting the oil pumping structure and the second bearing. The oil-bath engine coupling device provided by the invention effectively improves the heating phenomenon and lubrication effect of the first bearing and the second bearing, thereby increasing the service life of the coupling device during the engine test process.

Description

technical field [0001] The present application relates to the technical field of engine development and testing, in particular to an oil bath type engine coupling device and an engine testing device. Background technique [0002] Reliability verification is required during the engine development process. During the engine test, the engine output needs to be connected with the dynamometer to absorb and measure the engine output. In order to protect the prototype and the dynamometer during the test, it is necessary to add an overload and fault protection device between the engine output end and the dynamometer to minimize the loss in the event of a failure. During the test, the speed and load of the engine change greatly, the speed and load of the shaft and bearing are large, and the bearing is prone to abnormal damage such as heat and wear. A set of shaft systems usually cannot accompany the test until the test is completed. Therefore, a test scene requires a Long life, high...
