Embodiment Construction
[0015] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0016] Such as Figure 1 to Figure 2 As shown, the present invention will hex screw 1 (see image 3 ) on one end of the external threaded end 1-1 is fixed on the motor end cover 5, and the motor speed encoder 3 is locked and fixed in the internal threaded hole 1-2 at the other end of the hexagonal screw 1 through the mounting hole and fasteners, so as to provide Fixed tachometer encoders provide mounting support points. At the end of the motor shaft, the mounting surface of the flange 4 is locked on the threaded hole reserved on the motor shaft through bolts, so that the flange 4 is synchronized with the motor shaft, that is, the speed of the flange 4 is the speed of the motor shaft ,Such as Figure 4 , Figure 5 The size of the shaft head 4-1 of the shown flange 4 is matched according to the size of the installation inner hole of the ...

The invention discloses a mounting structure of a motor speed test encoder. The outer thread end at one end of a hexagonal lead screw is fixed to a motor end cover; a motor speed test encoder is fixedly locked to an inner thread hole at the other end of the hexagonal lead screw through a mounting hole and a fastening piece; a flange is locked to a thread hole reserved on a motor rotary shaft through a bolt at the end part of the motor rotary shaft; and the size of a shaft head of the flange is made corresponding to that of an mounting inner hole of the speed test encoder, and the shaft head of the flange extends in the mounting inner hole of the speed test encoder in mounting process. The speed test encoder and the motor rotary shaft are connected into an integrated body by the flange through a mounting stop surface and a bolt, so that the rotary speed of the motor rotary shaft is effectively transmitted to the test speed encoder; the speed test encoder has a reliable mounting supporting point due to the application of a double thread screw, so that the speed test encoder can be effectively mounted; and a protection cover structure also brings effective protection to the encoder for preventing the encoder being damaged accidently so as to avoid unnecessary economic loss.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to the installation structure of motor speed measuring encoders. Background technique [0002] In ordinary Z series medium and large motors, a speed measuring encoder is often used to measure the actual speed of the motor. However, the installation structure of the existing speed measuring encoder is relatively complicated, resulting in difficult installation and inaccurate speed measurement. Contents of the invention [0003] In view of the disadvantages of the above-mentioned existing speed measuring encoder installation structure being relatively complicated, the applicant provides a motor speed measuring encoder installation structure, which is easy to operate, simple and reliable in structure, and effectively solves the installation problem of the motor speed measuring encoder. [0004] The technical scheme adopted in the present invention is as follows: [0005] A motor spee...
