[0022] 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. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Please refer to Figure 1 - Figure 2 The utility model provides an embodiment: a heavy-load spherical roller bearing for a crusher, including an outer ring 1, which is made of high-strength alloy steel and provides a stable installation and operation basis for the roller and inner ring. A tapered roller 2 is arranged inside the outer ring 1. This device is a tapered roller bearing, and a load mechanism 3 is arranged on the inner wall of the outer ring 1, and a stabilizing mechanism 4 is arranged inside the tapered roller 2.
[0024] Please refer to Figure 1 - Figure 3 The mounting assembly includes a sleeve 301, both ends of the sleeve 301 are provided with springs, the inner wall of the sleeve 301 is slidably connected to the telescopic rod 302, the end of the telescopic rod 302 away from the sleeve 301 is fixedly connected to the carrying plate 303, the carrying plate 303 moves under pressure, and the carrying plate 303 enables the telescopic rod 302 to telescope along the inside of the sleeve 301, the surface of the sleeve 301 is fixedly connected to the inner wall of the outer ring 1, and the surface of the telescopic rod 302 is provided with a spring.
[0025] Please refer to Figure 1 - Figure 3 The load mechanism 3 is composed of a mounting assembly and a load assembly. The load assembly includes a transmission rod 304. The carrier plate 303 drives the transmission rod 304 to move. The upper end of the transmission rod 304 is hinged with a push block 305. The transmission rod 304 drives the push block 305 to slide along the inner wall of the outer ring 1. The top of the push block 305 is hinged with a connecting rod 306. The push block 305 drives the connecting rod 306 to be ejected outward. The end of the connecting rod 306 away from the push block 305 is hinged with a stop block 307. The connecting rod 306 drives the stop block 307 along the inner wall of the outer ring 1. Figure 1It extends in the radial direction, and the end of the transmission rod 304 away from the pushing block 305 is rotatably connected to the carrier plate 303. The outer surface of the pushing block 305 is slidably connected to the inner wall of the outer ring 1, and the outer surface of the support block 307 is in contact with the inner wall of the outer ring 1, thereby achieving the effect of stabilizing the radial load of the roller bearing, increasing its axial load capacity, and enabling it to maintain good performance even when bearing heavy axial loads.
[0026] Please refer to Figure 4 The stabilizing mechanism 4 includes a sleeve 403, and a reducing piece 404 is provided on the surface of the sleeve 403. When the main rotating rod is inserted into the interior of the sleeve 403, the reducing piece 404 allows the main rotating rod to be smoothly inserted into the bearing through its plasticity. The sleeve 403 is connected to the inner wall of the tapered roller 2. The reducing piece 404 is a plastic piece, and a stop protrusion is provided on its surface. The stabilizing mechanism 4 also includes a fixing ring 401. The operator slides the fixing ring 401 toward the sleeve 403. The surface of the fixing ring 401 is provided with a friction strip 402, so that the fixing ring 401 and the surface of the sleeve 403 are clamped. The inner surface of the fixing ring 401 and the outer surface of the sleeve 403 contact each other, which increases the firmness between the bearing and the rotating rod, reduces the wear, vibration and noise caused by looseness, thereby reducing the failure risk of the bearing and the rotating rod, and improving the reliability and stability of the equipment.
[0027] Working principle: When the operator is installing the bearing, he inserts the rotating rod into the interior of the sleeve 403. The rotating rod can be smoothly fixed by the plastic action of the reducer 404. At the same time, the fixing ring 401 is slid toward the sleeve 403, so that the fixing ring 401 firmly clamps the sleeve 403 and the rotating rod, thereby increasing the firmness between the bearing and the rotating rod, reducing the wear, vibration and noise caused by looseness, thereby reducing the risk of failure of the bearing and the rotating rod, and improving the reliability and stability of the equipment. At the same time, when the bearing is subjected to axial load pressure, the bearing plate 303 is pressed to move, and the bearing plate 303 makes the telescopic rod 302 telescopes along the inside of the sleeve 301, playing a certain buffering role. At the same time, the carrying plate 303 drives the transmission rod 304 to move, and the transmission rod 304 drives the push block 305 to slide along the inner wall of the outer ring 1. The push block 305 drives the connecting rod 306 to be pushed outward, so that the support block 307 extends in the radial direction until it contacts and firmly resists the obstacle, achieving the effect of stabilizing the radial load of the roller bearing, increasing its axial load capacity, and being able to maintain good performance when bearing heavy axial loads, reducing production interruptions caused by equipment failure or maintenance, and helping to improve production efficiency and output.
[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
