High torsion-resistance connecting device capable of quickly connecting with engine to rotate

Abstract

The invention discloses a high torsion-resistance connecting device capable of quickly connecting with an engine to rotate. The device comprises a connecting shaft, a shaft sleeve, a lock plate, a spring, a spring positioning shaft, a connecting disk, a connector, a middle shaft and a middle shaft permanent seat, wherein the left part of the connecting shaft is provided with a spline, and four bosses are evenly distributed on the right part of the connecting shaft; the right end of the connecting shaft is provided with a spring spacing hole; the spring is distributed between the connecting shaft and the spring positioning shaft; the spring positioning shaft is connected with the connecting disk; the middle shaft permanent seat is connected with the middle shaft; and the lock plate, the shaft sleeve, the connecting disk, a connector and the middle shaft are connected in sequence. By use of the device, the engine and a dynamometer can guarantee to be quickly connected, meanwhile, the accuracy of measurement data can be guaranteed, and production efficiency is obviously improved.

Description

technical field [0001] The invention relates to the field of engine detection, in particular to a highly torsion-resistant connecting device that can quickly connect the engine to rotate. Background technique [0002] At present, when the engine is installed on the assembly line, it is necessary to start the engine and connect it to a dynamometer to measure various performances. Now the connecting shaft of the dynamometer is directly connected to the engine or connected through an intermediate shaft, and a dynamometer is required for connection. Only when the connecting shaft is accurately matched with the engine can it be connected smoothly, which makes it impossible to connect quickly and the measurement speed is slow, resulting in low installation efficiency of the entire assembly line. At the same time, the method of directly connecting with the dynamometer has no buffer during measurement and can be used for a long time In the end, it will cause damage to the dynamomete...

Problems solved by technology

[0004] The present invention aims at the difficulty of connecting the engine and the dynamometer when using the dynamometer to measure various performances of the engine, and it takes too long to measure an engine. The dynamometer will be damaged after time use, causing the difficult problem of excessive measurement data error, providing a high torsion resistance connection device that can quickly connect the engine rotation

The device can be quickly connected to the engine, and also has high torsion resistance and buffer performance, which solves the difficulty in connecting the dynamometer to the engine, slow measurement and damage to the dynamometer after long-term use, resulting in excessive errors in measurement data big problem
