Embodiment Construction

[0051] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the coupling and the shaft connection structure of the present invention will be further described in detail below through embodiments and in conjunction with the drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0052] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements. The terms "vertical", "horizontal", "left", "right" and similar expressions us...

Abstract

The invention relates to the technical field of shaft transmission, in particular to a coupler. The coupler comprises a first shaft sleeve, a second shaft sleeve and an elastic limiting ring; one end of the first shaft sleeve is used for connecting with a first shaft, the other end of the first shaft sleeve is used for transmission connection with one end of the second shaft sleeve, and the other end of the second shaft sleeve is used for being connected with a second shaft; and the elastic limiting ring sleeves the connecting position of the first shaft sleeve and the second shaft sleeve, and therefore looseness of the first shaft sleeve and the second shaft sleeve is prevented. According to the coupler, the first shaft sleeve and the second shaft sleeve are used for connecting the first shaft and the second shaft correspondingly, the first shaft sleeve and the second shaft sleeve are in transmission connection, and therefore torque transmitting can be achieved through the first shaft and the second shaft; meanwhile, the elastic limiting ring sleeves the connecting position of the first shaft sleeve and the second shaft sleeve so as to prevent looseness of the first shaft sleeve and the second shaft sleeve, and therefore transmission connection of the first shaft sleeve and the second shaft sleeve is more reliable, and transmission of the first shaft and the second shaft is safer and more reliable.

Description

Technical field [0001] The invention relates to the technical field of shaft transmission, in particular to a coupling and a shaft connection structure. Background technique [0002] Couplings are commonly used in HVAC equipment to connect the motor shaft and the rotating shaft. Through the coupling, the length of the motor shaft can be reduced, the installation of the fan blades is convenient, and the transportation is convenient. [0003] The commonly used coupling is a sleeve structure, the two ends of which are respectively connected with the motor shaft and the rotating shaft, and the sleeve is provided with holes for passing screws. The motor shaft and the rotating shaft are set in a flat position, and the motor shaft and the rotating shaft are fixed by the hexagon socket screw. The screw must be tightened with a tool during installation, and the coupling and the motor shaft are not positioned, and the screw needs to be turned to a proper position to drive the screw to the fl...
