Problems solved by technology

[0002] In ordinary Z series and large motors, it is often necessary to measure the actual speed of the motor. The speed measuring device often chooses a speed measuring encoder. In a conventional motor, only one end is connected to the load, and the other end is connected to the encoder for speed measurement. In some special occasions, when both ends of the motor are loaded, there will be situations where the speed measuring encoder cannot be installed.

Embodiment Construction

[0014] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, when both ends of the motor are loaded, the traditional speed measuring encoder cannot be installed so that the speed of the motor cannot be accurately measured. figure 2 Give figure 1 Bring the velocity measuring device of the present invention, thereby solved figure 1 In order to solve the problem that the speed measuring encoder cannot be installed in the motor, a reliable structure is provided for accurately measuring the speed of the motor with loads at both ends. Such as figure 2 As shown, the first gear 2 is installed on the motor rotating shaft 1 through a shrink fit, and the second gear 3 is installed on the speed measuring rotating shaft 5 through a shrink fit (such as image 3 As shown), the first gear 2 and the second gear 3 are meshed to accurately transmit the rotational speed of the moto...

Abstract

The invention discloses a motor speed measuring device. The motor speed measuring device comprises a motor rotating shaft and a speed measuring rotating shaft, wherein the motor rotating shaft is hotly sleeved with a first gear; the speed measuring rotating shaft is hotly sleeved with a second gear; the first gear and the second gear are engaged by a gear; an encoder is mounted on the speed measuring rotating shaft; the speed measuring rotating shaft is mounted in a lug boss inner hole structure of an end cover by a bearing. The speed measuring device is simple and compact in structure, and reliable; the problem that the rotating speed of a motor cannot be accurately measured under the condition that double shaft extension motors have loads is solved, so that the structure guarantees for reliable speed measurement of the motors are provided.

Description

technical field [0001] The invention relates to a motor speed measuring device and belongs to the field of motors. Background technique [0002] In ordinary Z series and large motors, it is often necessary to measure the actual speed of the motor. The speed measuring device often chooses a speed measuring encoder. In a conventional motor, only one end is connected to the load, and the other end is connected to the encoder for speed measurement. In some special occasions, when both ends of the motor are loaded, the speed measuring encoder cannot be installed. Contents of the invention [0003] The purpose of the present invention is to solve the installation problem of the speed measuring encoder when both ends of the motor shaft extension are loaded, and provide a motor speed measuring device to realize the installation of the speed measuring encoder when the double shaft extension motor is loaded. [0004] Technical scheme of the present invention is as follows: [0005...
