Description

Technical Field

[0001] The utility model relates to the technical field of encoder installation structures, in particular to an installation structure of a self-fan-cooled vertical variable frequency motor encoder. Background Art

[0002] With the development of variable frequency speed regulation technology, especially the increasing maturity of motor-inverter-encoder speed closed-loop control technology, the control accuracy requirements of equipment in related fields are becoming more and more important. Due to the need to achieve precise speed control, traditional self-fan-cooled vertical variable frequency motors also need to be equipped with encoders.

[0003] The existing motor encoder installation method involves securing the encoder to the outside of the fan cover with a tie rod, connecting the encoder to the motor shaft via a connecting shaft, and then installing an encoder protective cover. This installation method leaves a large gap between the fan cover and the motor end cap, preventing coaxiality with the encoder and providing rain protection. Frequent jerking of the motor can damage the connecting shaft or encoder, affecting motor speed feedback, preventing precise control, and potentially causing equipment failure. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a mounting structure for a self-fan-cooled vertical variable frequency motor encoder which ensures accuracy, is easy to assemble and maintain, and is rainproof and has good heat dissipation effect.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides an installation structure for a self-fan-cooled vertical variable-frequency motor encoder, comprising a motor non-axial end cover, a fan cover, a rainproof cap, an encoder, a motor shaft and a fan, wherein the fan cover is arranged on the motor non-axial end cover, the motor shaft is supported and mounted on the motor non-axial end cover through a bearing assembly and rotates to extend outside the fan cover, the fan is fixed on the motor shaft and is located between the motor non-axial end cover and the fan cover, the encoder is fixed on the fan cover, the motor shaft is connected to the small shaft of the encoder through a connecting shaft, the motor shaft, the connecting shaft and the small shaft of the encoder are concentrically arranged, and the rainproof cap is fixed on the fan cover and the cover is arranged outside the encoder.

[0006] The motor non-shaft extension end cover and the fan cover are positioned by a stopper and fixedly connected by bolts.

[0007] Furthermore, a screw is welded on the fan cover, and the rainproof cap is fixed on the screw.

[0008] Furthermore, a fixing nut is fixed on the fan cover, a stud is connected to the fixing nut via a thread, a connecting piece is provided on the encoder, and the encoder is fixed to the stud via the connecting piece.

[0009] Furthermore, the fan cover is provided with reinforcing ribs.

[0010] Furthermore, a heat dissipation net is provided on the fan cover.

[0011] Furthermore, the size of the rainproof cap is larger than the size of the fan cover.

[0012] Furthermore, the fan cover is made of steel and has a thickness of 3 mm.

[0013] The beneficial effects achieved by the utility model using the above structure are as follows: in this solution, the fan cover is installed on the non-axial end cover of the motor by using a stopper, and is reinforced with ribs, and is made of 3mm thick steel plate, which can not only ensure the strength of the fan cover, but also ensure that the fan cover as a whole is not easily deformed, thereby ensuring the coaxiality of the small shaft of the encoder fixed on the fan cover and the motor shaft, protecting the encoder from damage; in this solution, the fan cover and the rain cap are installed separately by means of screws welded on the fan cover, which has a simple structure and is easy to adjust the position of the rain cap. A heat dissipation net is provided on the fan cover to facilitate heat dissipation. At the same time, the size of the rain cap is larger than the size of the fan cover, so it does not affect the air path, and can achieve the effect of ventilation, cooling and rain protection; this solution has a simple structure and is easy to install, which greatly saves material usage, while ensuring its strength, ensuring that it is not easily damaged during use, and improving motor performance.
