Description

Technical Field

[0001] The utility model relates to the field of tools for heat exchange station maintenance, and particularly relates to a bearing extractor. Background Art

[0002] The existing technologies are currently rather messy and lack strong pertinence. Some pullers are too heavy, making them not very practical in actual operation. The chucks are not firm, prone to falling off, or unable to extract the bearing due to the small gap between the bearing and the motor rotor, resulting in low maintenance efficiency.

[0003] The existing triangular pulley pullers or bearing pullers have chucks that are not firm, prone to falling off, or unable to extract the bearing due to the small gap between the bearing and the motor rotor, resulting in low maintenance efficiency. Summary of the Utility Model

[0004] An object of the utility model is to provide a bearing extractor that can at least solve any one of the above technical problems.

[0005] A further object of the utility model is to avoid the chuck being not firm and low maintenance efficiency.

[0006] Another further object of the utility model is to improve the maintenance effect and make the bearing firmly fixed and not prone to falling off.

[0007] In particular, the utility model provides a bearing extractor, which includes symmetrically arranged bearing clamping plates, and orientation nuts are arranged at both ends of the bearing clamping plates;

[0008] Orientation bolts, and the orientation bolts pass through the orientation nuts arranged at both ends of the bearing clamping plates;

[0009] Support pull rods, and one end of the support pull rods is fixedly connected to the middle of the orientation bolts;

[0010] Ejector rods, and the ejector rods are arranged at the other ends of the support pull rods.

[0011] Further, at least two orientation nuts are provided.

[0012] Further, at least one orientation nut is arranged at both ends of the orientation bolts.

[0013] Further, opposite clamping bases are arranged on the bearing clamping plates, and the clamping bases are slidably connected to the bearing clamping plates.

[0014] The technical effects and advantages of the utility model:

[0015] In this application, by setting two symmetric bearing clamping plates, the bottom of the bearing is fixed by the clamping plates. At the same time, two sets of orientation nuts are provided at both ends of the bearing clamping plates and used in combination with orientation bolts. During use, according to bearings of different sizes, the distance between the two bearing clamping plates can be adjusted to fit. When the bearing clamping plates abut against the bearing, a hydraulic device is used to press against the main shaft of the circulating pump above the bearing. By the lifting of the hydraulic device, the entire bearing clamping plate is pulled outwards, so as to remove the bearing fixed on the main shaft. It is convenient to use and easy to disassemble, greatly improving the maintenance and repair efficiency of the circulating pump in the heat exchange station. Brief Description of the Drawings
