    The invention relates to the combination of a radial bearing (38, 39) and a seal (42, 45, 46) which both make use of elastomeric bushings (42, 45) having a smooth cylindrical surface supporting a shaft (36) provided with helical grooves conveying the lubricating liquid said helical grooves conveying in the same or opposite directions, said combination of radial bearing and seal further can be combined with an axial bearing 40 having grooves in a disc 53 which rotates with the shaft (36) and which is in engagement with stationary discs 54, 55 of elastomeric material.

    专利说明:

    The invention relates to mechanical engineering and can be used, for example, in a dredger. A bearing assembly is known, which contains a shaft with a spiral groove, extending in opposite directions from the center of the assembly, two radial sliding bearings in the form of stationary cylindrical bushings, .Htie axially located on the shaft from the ends of the bearing bearings and lubricant supply located at the center of the assembly 13 However, the known bearing assembly does not work well in a polluted environment, since it does not have any design features for the removal of soil particles from the zone of friction. The aim of the invention is to increase the durability of the bearing assembly by eliminating contaminants from the zone of friction. The goal is achieved by the fact that a bearing assembly containing a shaft with a spiral groove extending to different directions from the center of the assembly, two radial sliding pads in the form of stationary cylindrical sleeves axially located on the shaft from the ends of the seal bearings and lubricant delivery means located in the center of the assembly , additionally provided with a stop disc with radial grooves / one jfS of the KOTOptox side surfaces is located at an acute angle to the working surface, and interacting with it installed in The pads have working pads whose working surfaces are covered with elastomeric material and the seals are made in the form of elastomer bushings having a h-shaped axial section, with smooth internal surfaces in contact with the spiral groove of the shaft having one lateral surface located at an acute angle to shaft axis. The drawing shows the bearing assembly of the pump, the cross section. In case 1, there is a blade 2 mounted on shaft 3. In case i of bearing assembly 4, the shaft is supported by two radial bearings in the form of bushings 5 and b and thrust bearing 7. mechanical seals 8 and 9. Lubrication from reservoir 10 by means of pump 11 through filters 12, designed to remove small contaminants, is fed into the cavity formed between the housing and the thrust bearing consisting of a disk 13 rigidly mounted on the shaft, interacting with the disks 14 and 15, rigidly fixed in the housing of the bearing assembly 4 and having smooth working surfaces facing the disk. Spiral grooves are made on the working surfaces of the disk. The lubricant then goes to the radial bearings and seals, through which it is driven through the interaction of the shaft with the grooves with the elastic sleeves. If the working medium does not contain abasive particles and is suitable for washing and cooling bearings and seals, then it can be supplied through HOD 16.
