Description

Technical Field

[0001] The utility model relates to the field of rotor offline dynamic balance correction, in particular to a universal rotor positioning sleeve. Background Art

[0002] Long-term operation of rotating equipment such as dust removal fans, compressors, and water pumps often results in increased vibration due to impeller wear and corrosion, which is detrimental to safe production. Current solutions include on-site and offline dynamic balancing. These rotors typically have a shaft diameter of less than 150mm on the opposite side and low rotational speeds.

[0003] When performing offline dynamic balancing of the rotor, the rotor needs to be reliably connected to the universal joint flange of the dynamic balancing machine. During this process, it is necessary to ensure that the center of rotation of the rotor coincides with the center of the universal joint flange to ensure the accuracy of the dynamic balancing calibration. Utility Model Content

[0004] The utility model provides a universal rotor positioning sleeve to ensure that the rotor rotation center coincides with the center of the universal joint flange.

[0005] In order to solve the above problems, the utility model provides a universal rotor positioning sleeve adopting the following technical solutions:

[0006] A universal rotor positioning sleeve includes a sleeve, with the axis of the sleeve as the left and right direction. At least three positioning plates are provided in the sleeve, and the positioning plates are evenly arranged along the circumferential direction of the axis of the sleeve. The cross-section of the positioning plates on the vertical plane gradually decreases from left to right to form a placement space for the rotor in the sleeve. The size of the placement space gradually decreases from left to right to accommodate rotors of different sizes.

[0007] The beneficial effect is that when the universal rotor positioning sleeve of the utility model is used, the rotor is positioned by the positioning plate. After the rotor is inserted into the placement space, the rotor is continuously pushed forward until the rotor can no longer move to the right, at which point the rotor axis automatically coincides with the axis of the sleeve. When the universal rotor positioning sleeve of the utility model is used, the positioning plate ensures that the rotor axis is coaxial with the sleeve axis after the rotor is pressed against the positioning plate, thereby facilitating the coaxiality of the rotor and the flange.

[0008] Furthermore, four positioning plates are provided.

[0009] Furthermore, the positioning plates are triangular plates, and four positioning plates form a quadrangular pyramid structure.

[0010] Beneficial effects: simple structure, easy to install and manufacture.

[0011] Furthermore, a connecting plate is provided on the right end face of the sleeve, and a plurality of flange holes are opened on the connecting plate. The flange holes are evenly distributed along the circumferential direction of the sleeve and are adapted to the flange to connect the sleeve and the flange.

[0012] Beneficial effects: simple structure and easy to connect with flange.

[0013] Furthermore, at least three positioning holes are evenly distributed in the circumferential direction of the left end of the sleeve, and a positioning rod is passed through each positioning hole to tighten the rotor.

[0014] Beneficial effect: Used to push the rotor in and prevent it from loosening during operation.

[0015] Furthermore, four positioning holes are provided, and the four positioning holes are evenly distributed along the circumference of the sleeve.

[0016] Furthermore, the positioning hole is a threaded hole, the positioning rod is a threaded rod, and the positioning rod is threadedly connected in the corresponding positioning hole.

[0017] Beneficial effects: simple structure, easy to install and adjust. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0026] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0027] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0029] like Figure 1 、 Figure 2 and Figure 3 As shown, a universal rotor positioning sleeve of the present invention includes a sleeve 1, a positioning rod and a positioning plate 2, with the axis of the sleeve 1 as the left and right direction.

[0030] A connecting plate 3 is provided on the right end face of the sleeve 1. A plurality of flange holes 4 are formed on the connecting plate 3. The flange holes 4 are evenly distributed along the circumference of the sleeve 1 and are adapted to the flange to connect the sleeve 1 to the flange.

[0031] Four positioning holes 5 are evenly distributed in the circumferential direction of the left end of the sleeve 1, and each positioning hole 5 is a threaded hole.

[0032] The positioning rod is a threaded rod, which is threadedly connected to the corresponding positioning hole 5.

[0033] There are four positioning plates 2 , all of which are triangular plates. Adjacent side surfaces of any two adjacent positioning plates 2 are welded together to form a quadrangular pyramid structure.

[0034] The cross section of the positioning plate 2 on the vertical plane gradually decreases from left to right to form a placement space for placing the rotor in the sleeve 1. The size of the placement space gradually decreases from left to right to accommodate rotors of different sizes.

[0035] When in use, the universal rotor positioning sleeve of the utility model positions the rotor through the positioning plate. After the rotor is inserted into the placement space, the rotor continues to push forward until the rotor can no longer move to the right. At this time, the axis of the rotor automatically coincides with the axis of the sleeve, and then the positioning rod is rotated to fix the rotor.

[0036] When the universal rotor positioning sleeve of the utility model is in use, the positioning plate ensures that the rotor axis can be coaxial with the sleeve axis after the rotor is pressed against the positioning plate, thereby facilitating the coaxiality of the rotor and the flange.

[0041] The main difference between it and embodiment 1 is that: in embodiment 1, at least three positioning holes are evenly distributed in the circumferential direction of the left end of the sleeve, and a positioning rod is passed through each positioning hole to tighten the rotor.

[0042] In this embodiment, no positioning holes and positioning rods are provided.
