Embodiment 1

[0038] refer to figure 1 -5, a tensioning sleeve according to the embodiment of the present invention, including an outer sleeve 100 and an inner sleeve coaxially socketed, the outer sleeve 100 is used to be closely attached to the outer structural member; and the outer sleeve 100 has a first hollow inner cavity for sleeve It is located outside the inner sleeve; the inner sleeve has a second hollow inner cavity for tightly holding the inner structural member; the outer sleeve 100 and the inner sleeve are connected through a connecting component to connect the inner structural member and the outer structural member coaxially.

[0039] In the transmission of rotational kinetic energy, whether the coaxial connection structure of the power output structure and the power transmission structure can maintain good coaxiality directly affects the accuracy and efficiency of power transmission.

[0040] Wherein, both the outer casing 100 and the inner casing are of a structure of revolut...

Embodiment 2

[0061] An embodiment of the present invention provides an electric motor, which includes a rotor, a stator, and a power output shaft, wherein the rotor is rotatably arranged in the stator, and the rotor and the power output shaft are coaxial through any tension sleeve provided in Embodiment 1. connect.

[0062] Among them, the specific structure of the tensioning sleeve has been introduced in detail above, and will not be repeated here.

[0063] In the electric motor, the power transmission between the power output shaft and the rotor is very critical, which directly affects the normal operation and performance of the electric motor. It can be seen that the rotor of the motor is connected to the power output shaft through the above tension sleeve, which can achieve all the beneficial effects that the above tension sleeve can achieve, improves the coaxiality and stability of the rotor and the power output shaft, and effectively prevents the motor from Instability and even swin...

Abstract

The invention relates to the technical field of mechanical equipment, in particular to a tensioning sleeve and a motor. The tensioning sleeve comprises an outer sleeve body and an inner sleeve body, wherein the outer sleeve body coaxially sleeves the inner sleeve body; the outer sleeve body is used for being tightly attached to the inner portion of an outer structural par and is provided with a first hollow inner cavity, and the first hollow inner cavity is used for sleeving the inner sleeve body; the inner sleeve body is provided with a second hollow inner cavity, and the second hollow innercavity is used for holding an inner structural part tightly; and the outer sleeve body and the inner sleeve body are connected through a connecting assembly so as to enable the inner structural part and the outer structural part to be coaxially connected. The tensioning sleeve has the advantages of being simple in structure and convenient to use, the coaxial connection structure of the inner structural part and the outer structural part can be ensured, the structure that the inner structural part is arranged in the outer structural part in a sleeved mode is stable, and safe and stable operation of equipment can be ensured.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a tensioner sleeve and a motor. Background technique [0002] In the field of mechanical equipment, power transmission structures are often involved, especially rotational kinetic energy transmission. In the transmission of this rotational kinetic energy, the power output structure and the power transmission structure are generally connected coaxially to ensure the accuracy and efficiency of power transmission, especially in the motor, the power transmission between the power output shaft and the rotor It is very critical and directly affects the normal operation and performance of the motor. [0003] However, in the existing equipment, the connection between the power output structure and the power transmission structure is simply sleeved together, the coaxiality is low, and the stability after installation is poor. [0004] The information disclosed in this Backg...
