After exceeding this range, it is easy to damage the encoder or coupling
[0004] The utility model patent "Installation Structure of Rotary Shaft Speed Encoder for Textile Machinery" (Application No.: 201420010270.6) is connected to the end faces of the flanges of the couplings connected to the encoder shaft and the measured shaft respectively by magnets. Although this connection method avoids the adverse effects caused by the different axes or angles between the encoder shaft and the measured shaft, due to the introduction of magnets, it will cause interference on the test signal to the test component or test system. Affect the normal operation of test components or test systems

Embodiment Construction
[0020] The present invention will be further described below in conjunction with accompanying drawings and examples.
[0021] Such as Figure 2 to Figure 6 As shown, a rotary encoder installation structure is mainly composed of three parts such as a casing 2-1, a supporting shell 2-2, and a tension spring 2-3.
[0022] Tension spring 2-3 is the suitable spring of the same specification, and one end of tension spring 2-3 is connected with casing 2-1, and the other end is connected with support shell 2-2, so that support shell 2-2 basically It is in the middle of the casing 2-1. The supporting shell 2-2 is mainly used to support and support the rotary encoder 1 .
[0023] Such as figure 1 As shown, when in use, insert the rotary encoder 1 into the supporting shell 2-2 and connect and fix the end of the rotary encoder 1, so that the rotary encoder 1 and the supporting shell 2-2 are basically in the middle of the shell 2-1 And only rely on the tension spring 2-3 to connect. S...

The present invention relates to a rotary type encoder mounting structure, which consists of a cover casing, a support shell and extension springs. The support shell is arranged in the cover casing. The support shell and the cover casing are connected by a plurality of extension springs, and the support shell is generally arranged in a middle position of the cover casing. The cover casing is fixedly connected with a rack or a support of a device where a tested shaft is arranged. A rotary type encoder is installed in the support shell. A spindle of the rotary type encoder is connected to the tested shaft through a shaft coupling and is used for measuring angular displacement or rotating speed parameters of the tested shaft. The rotary type encoder mounting structure can be applied to the mounting of a common rotary type encoder at present. The mounting structure can prevent the encoder and the shaft coupling from being damaged, and the use cost is saved. At the same time, the requirement of the shaft coupling can be reduced and the quality requirement of assembly persons can be reduced.
Description
technical field [0001] The invention relates to an encoder installation structure, in particular to an installation structure used for the installation and connection between a rotary encoder and a tested shaft, which also has the functions of supporting and connecting the encoder. Background technique [0002] Rotary encoders are widely used in the testing industry and can be used to test the angular displacement and rotational speed of the measured shaft. The most common installation method for general encoders is: the encoder is installed and fixed on the bracket, and the encoder shaft and the measured shaft are connected through an elastic coupling. [0003] The invention patent "An Encoder Installation Device for Variable Frequency Motor" (application number: CN201210160487.0) is an example of installing the encoder on the bracket and connecting it through an elastic coupling. Although this installation connection is simple in structure, it has certain range requiremen...
