Problems solved by technology

[0002] The tachometer is one of the necessary instruments in the mechanical industry. It is used to measure the rotational speed, linear speed or frequency of the motor. It is used in the manufacturing industries such as motors, electric fans, and papermaking. Mechanical speed and cumulative use time, now many tachometer indicators generally use a mixture of graphics and graphics numbers, but this kind of reading accuracy is low, the structure is more complicated, and the scope of application is small

Abstract

The invention discloses an indicator for an electric tachometer. The indicator comprises a shell having a hollow structure; the shell comprises a cylinder part and a vertical plate part, the inner part of one end of the cylinder part of the shell is connected with a shell mounting part also having a hollow structure, the end part, arranged at one end in the shell, of the shell mounting part is connected with a supporting device, a horizontal bar is connected to the inner part of the shell mounting part, one end of the horizontal bar is connected with one end of the supporting device and provided with a pointer mounting part, a dial, an indicating sub-component and a damper from left to right, a transparent cover is arranged at the other end close to the horizontal bar, the other end of the supporting device is connected with a motor component, a plug is inserted into the shell and the vertical plate part, and the plug and the motor component are connected with each other by wires. The indicator of the invention has the advantages of simple structure and accurate reading.

Description

Technical field: [0001] The invention relates to an indicator, in particular to an indicator of an electric tachometer. Background technique: [0002] The tachometer is one of the necessary instruments in the mechanical industry. It is used to measure the rotational speed, linear speed or frequency of the motor. It is used in the manufacturing industries such as motors, electric fans, and papermaking. For the mechanical speed and cumulative use time, many tachometer indicators now generally use a mixture of graphics and graphics and numbers, but this kind of reading accuracy is low, the structure is more complicated, and the scope of application is small. Invention content: [0003] The object of the present invention is to overcome the above disadvantages and provide an indicator of an electric tachometer that has a simple structure, accurate readings, and can be used in the range of -20°C to +50°C. [0004] The purpose of the present invention is achieved through the fo...
