Motorcycle chain tightener detection device

Abstract

The invention discloses a motorcycle chain tightener detection device comprising a base, a column, a variable frequency motor and a decelerator which is connected with the main shaft of the variable frequency motor. The motorcycle chain tightener detection device is characterized by further comprising a fixedly arranged micro-range torque sensor. One end shaft of the micro-range torque sensor is connected with the output shaft of the decelerator, and the other end shaft of the micro-range torque sensor is connected with a connecting shaft. A key poking sheet is connected on the connecting shaft. The column is fixedly provided with a load guide plate, a detection installing plate and a workpiece installing plate which are arranged from the top to the bottom in turn. A longitudinal pressing rod slidably penetrates through the load guide plate. A counterweight and a pressing disc are fixedly arranged on the pressing rod. A dial indicator is arranged on the detection installing plate. The pressing disc is arranged above the measuring head of the dial indicator. A longitudinal through hole is arranged on the workpiece installing plate. The key poking sheet penetrates through the through hole and is arranged above the workpiece installing plate. Whether the torque value of the plane volute spiral spring meets the requirements can be accurately detected so that the performance of the tightener can be guaranteed, the judgment mode is simple and visual and the detection efficiency can be enhanced.

Description

technical field [0001] The invention relates to a detection device for a motorcycle chain tensioner. Background technique [0002] The camshaft overhead valve mechanism of a motorcycle engine generally uses a chain drive because the center of the camshaft is far from the center of the crankshaft. In order to prevent the chain from slack, vibration and noise when the engine is running at high speed, middle and high-end motorcycles are generally equipped with a chain tensioner in the middle of the chain to ensure that the chain has a certain tension when the engine is working, and can Adjust according to chain elongation and wear at any time. Commonly used chain tensioners such as figure 1 As shown, it includes a base 41, a special stud 42 threaded with the base 41, a sleeve 43 threaded with the special stud 42, a key hole 45 is provided on the base 41, and a plane scroll spring 44 One end is fixed in the groove on the special stud 42, and the other end is fixed on the slee...

AI Technical Summary

Problems solved by technology

On the motorcycle, the top of the sleeve 43 is in contact with the motorcycle chain; when the chain is too loose, the energy stored in the planar scroll spring 44 drives the sleeve 43 to rotate, thereby tensioning the motorcycle chain; by the above work It can be seen from the principle that the performance of the flat scroll spring 44 in the tensioner determines the accuracy of the tensioner, so the torque value of the flat scroll spring 44 becomes a key parameter to determine the performance and accuracy of the motorcycle chain tensioner ; but currently there is no corresponding device for the tensioner of this structure to detect the torque of the plane scroll spring, and the performance of the tensioner cannot be guaranteed
