Problems solved by technology

At present, the lower bearing of the mixing bucket bearing seat is equipped with a gland with a trapezoidal groove, and the cow felt is inserted into the trapezoidal groove for sealing, so it is difficult to replace the cow felt. Slurry enters the bearing and aggravates the wear of the bearing, resulting in frequent shutdowns for maintenance

Embodiment 1

[0014] Such as figure 1 As shown, this embodiment provides a sealing device with a rubber layer for a mixing bucket bearing, including an end cover 2, a cover 3, and a double-layer skeleton oil seal. The end cover 2 is installed on the outer end side of the bearing 1, and the end cover 2 is close to the A rubber layer 6 is arranged on the end surface of the bearing, and a sealing groove 4 is arranged on the end cover 2 far away from the middle of the bearing end surface.

[0015] Further, the rubber layer 6 is bonded on the end surface of the end cover 2 close to the bearing end by vacuum suction. The rubber layer is placed between the bearing and the end cover with a thickness of 3mm to buffer the pressure generated by installing the end cover through bolt fastening and prevent dust from entering.

[0016] Still further, the cover 3 is provided with a through hole, the end cover 2 is provided with a threaded hole, and the cover 3 is screwed to the end cover 2 through a screw...

Abstract

The invention relates to a sealing device with a rubber layer for an agitation barrel bearing. The sealing device is characterized by comprising an end cover, a sealing cover and a dual-layer framework oil seal. The end cover is installed on the side of the outer end of the bearing. The rubber layer is arranged on the end face, close to the bearing end, of the end cover. The thickness of the rubber layer is 3 mm, a sealing groove is formed in the middle position of the end face, away from the bearing end, of the end cover, the sealing cover is installed on the end face, away from the bearing end, of the end cover, and the dual-layer framework oil seal is installed inside the sealing groove. By arranging the dual-layer framework oil seal inside the sealing groove, slurry is effectively prevented from entering the bearing, the service life of the bearing is prolonged, and the halt overhauling frequency is decreased. According to the sealing device, the framework oil seal can be replacedby disassembling and assembling the sealing cover, and overhauling is convenient.

Description

technical field [0001] The invention relates to the technical field of mixing buckets, in particular to a sealing device with a rubber layer for a mixing bucket bearing. Background technique [0002] The mixing tank needs to work continuously for a period of time to mix the slurry in the tank evenly. The lower bearing of the mixing bucket bearing seat is near the slurry and needs to be sealed to prevent the slurry from entering the bearing, so as to prevent the bearing from being worn out and shutting down for maintenance. At present, the lower bearing of the mixing bucket bearing seat is equipped with a gland with a trapezoidal groove, and the cow felt is inserted into the trapezoidal groove for sealing, so it is difficult to replace the cow felt. The slurry enters the bearing, aggravating the wear of the bearing, resulting in frequent shutdown for maintenance. Contents of the invention [0003] The object of the present invention is to provide a sealing device with a r...
