Description

Technical Field

[0001] The utility model relates to the technical field of slewing bearings, in particular to a flange type slewing bearing. Background Art

[0002] Slewing bearings are widely used in real industry and are called "machine joints". They are important transmission components required for machines that perform relative rotation between two objects and simultaneously bear axial force, radial force, and tipping moment. With the rapid development of the machinery industry, slewing bearings have been widely used in ship equipment, engineering machinery, light industrial machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.

[0003] As an important transmission component, the slewing bearing covers a wide range of fields. However, there are the following problems in the single-row ball slewing bearing:

[0004] First, the outer ring and inner ring of the slewing bearing are responsible for rotation and fixation respectively, but both the fixed part and the rotating part are directly fastened with bolts, and the fixing angle and method are very single, which is difficult to meet the needs of different customers;

[0005] In addition, the isolation blocks and balls in the slewing bearing need to be distributed in sequence between the outer ring and the inner ring. The conventional assembly method is to place them in the outer ring manually in advance. However, due to the small size of the slot, this feeding method is prone to the separation blocks and balls falling off, which increases the difficulty of assembly and prolongs the assembly time. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a flange type slewing bearing, which overcomes the deficiencies of the prior art and effectively solves the problems of single fixing angle and method and long assembly time.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A flange type slewing bearing, comprising an outer ring, the inner wall of the outer ring is rotatably connected to the inner ring, and the outer wall of the top of the inner ring is screwed with a fastening plate, the inner wall of the fastening plate is welded with a column, and the outer wall of the top of the column is welded with a top flange, the outer wall of the column is welded with a connecting sleeve, and the outer wall of the connecting sleeve is welded with side columns distributed at equal distances, and the outer wall of one end of the side column is welded with a side flange;

[0009] A feeding trough is provided on the inner wall of the inner ring, and a sealing block is connected to the inner wall of the feeding trough.

[0010] Preferably, an oil filling pipe is fixedly connected to the outer wall of the top of the outer ring, and a sealing plug is threadedly connected to the outer wall of one end of the oil filling pipe.

[0011] Preferably, the outer wall of the outer ring is provided with gear teeth distributed at equal distances.

[0012] Preferably, an inner groove is formed on the outer wall of the inner ring, and the inner wall of the feeding trough is connected to the inner wall of the inner groove.

[0013] Preferably, the outer ring and the inner ring are slidably connected with isolating blocks and balls which are equidistantly distributed.

[0014] Preferably, an outer groove is formed on the inner wall of the outer ring, and the isolation block and the ball are slidably connected to the inner wall of the outer groove.

[0015] The beneficial effects of the utility model are:

[0016] 1. The inner ring of the flange type slewing bearing of this design is used to fix the column by connecting the fastening plate. Since the top flange and the side flanges on multiple side columns are installed on the column, the top flange and the side flanges provide fixing points, and the fixing angles of the two parts are different. The flange type slewing bearing is adopted, which increases the fixing method and fixing angle of the slewing bearing, and effectively meets the use requirements of different customers;

[0017] 2. The flange type slewing bearing of this design has a feeding trough on the inner wall of the inner ring. The feeding trough is connected to the inner groove at an inclined angle. When assembling the isolation block and the ball, the operator can put them into the inner groove from the feeding trough in sequence, and seal them with a sealing block to prevent the isolation block and the ball from falling off, thereby reducing the difficulty of assembly and reducing the assembly time.
