Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

As shown in fig. 1-2, the utility model relates to a multifunctional bearing dismounting puller, which comprises a screw rod 2, the top of the screw rod 2 is provided with an external thread, the top of the screw rod 2 is provided with a rotating handle 1, the inside of the rotating handle 1 is provided with an internal thread, the external thread of the screw rod 2 is matched with the internal thread of the rotating handle 1, so that the rotating handle 1 and the screw rod 2 are relatively fixed, the bottom of the screw rod 2 is conical, which is convenient to be pressed against a bearing device, the middle part of the screw rod 2 is provided with a screw disk 3, the screw disk 3 is in threaded connection with the screw rod 2, the bottom of the screw rod 2 is provided with an iron plate 6 and a semicircular iron plate 7, the iron plate 6 and the semicircular iron plate 7 are in threaded connection with the screw disk 3 through a screw rod 4, the middle part of the iron plate 7 is provided with a first semicircular clamping groove 5, the middle part of the semicircular iron plate 7, the arc can be used as a bearing sleeve and sleeved on bearing equipment, two parallel slide ways 9 are arranged on the top surface of the iron plate 6, and the semicircular iron plate 7 is movably installed with the iron plate 6 through a connecting piece.
