Connecting device for engine and dynamometer

Abstract

The invention discloses a connecting device for an engine and a dynamometer. The connecting device comprises an L-shaped bracket, a support, an engine connecting base, a plurality of nylon sleeves, a bearing and a dynamometer connecting base. A flange at one end of the support is located in an inner hole of the upper end of the L-shaped bracket in the radial direction, and a plurality of fastening pieces enable the L-shaped bracket, the support and the engine to be connected into a whole. The nylon sleeves are embedded into a flange at one end of the engine connecting base respectively, and a plurality of fastening screws penetrate through the corresponding nylon sleeves respectively and enable the engine connecting base and a fly wheel of the engine to be fixedly connected. One end of the dynamometer connecting base is connected with the other end of the engine connecting base, the other end of the support is supported at the other end of the engine connecting base and one end of the dynamometer connecting base through the bearing, and the other end of the dynamometer connecting base is fixedly connected with an input end of the dynamometer. According to the connecting device for the engine and the dynamometer, a rigid connecting structure in the prior art is replaced by an elastic connecting structure for the engine and the dynamometer, the connecting device is good in centering performance, and the engine 1 and the dynamometer 3 are quite convenient to connect and dismantle.

Description

technical field [0001] The invention relates to a connecting tool for engine power testing, in particular to a connecting device between an engine and a dynamometer that is easy to install and has good neutrality, and belongs to the technical field of mechanical transmission. Background technique [0002] The power of the engine directly reflects the pros and cons of the power performance of the engine. Before the engine is used for the first time, it is often necessary to detect its power in order to determine the technical condition of the engine. Usually, the output end of the engine is connected to the input end of the dynamometer through a connecting device. When the engine is running, the dynamometer connected to it can measure the speed and torque data of the engine. like figure 1 As shown, the existing two-stroke gasoline engine 1 for brush cutters is connected to the dynamometer 3 through the connecting seat 2, and the bottom of the engine 1 is supported on the com...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, the existing two-stroke gasoline engine 1 for the brush cutter is connected to the dynamometer 3 through the connecting seat 2, and the bottom of the engine 1 is supported on the common base plate 5 through the support frame 4. This positioning method causes the center height of the engine 1 and The center height of the dynamometer 3 is difficult to be consistent, and the alignment of the connection between the engine 1 and the dynamometer 3 is difficult to ensure, resulting in a large error in the test results. In addition, the engine 1 and the support frame 4 need to be disassembled at the same time, which is very troublesome and labor-intensive , low work efficiency
