Problems solved by technology

As it is a welded part, the material is Q235 with good welding performance. However, in the actual use process, the bearing seat and the bearing often wear and loosen. Because it affects the normal operation of the equipment, it can only be shut down for maintenance. During maintenance, the entire bearing seat must be disassembled. In this case, replace the spare parts of the bearing seat prepared in advance, which will increase the replacement cost and cause unnecessary waste

Embodiment

[0026] A kind of split type drawing roller bearing seat, such as Figure 1-2 , the bearing seat includes a bolt-connected bearing main seat 1 and a bearing sub-seat 2, the bearing main seat 1 is welded on the installation base plate, and the bearing 20 is installed in the bearing sub-seat 2. The material of the bearing sub-seat 2 is 40Cr steel or quenched and tempered 45# steel, and the high-strength material is beneficial to prolong the service life of the bearing seat.

[0027] The main bearing base 1 is provided with 6 bolt holes 12 . The bearing sub-seat 2 is provided with bolt through holes 22 matching the position and quantity of the bolt holes 12 . The bearing main seat 1 and the bearing sub-seat 2 are connected by six symmetrically arranged bolts 3 . A spring washer 31 is arranged between the bolt 3 and the bearing sub-seat 2, which can reduce the wear effect of the bolt 3 on the bearing sub-seat 2.

[0028] A circular groove 11 is provided on the bearing main seat ...

Abstract

The invention relates to a split paper drawing roller bearing seat. The bearing seat comprises a bearing main seat (1) and a bearing sub-seat (2) which are connected through bolts. The bearing main seat (1) is welded on a mounting bottom plate, and a bearing (20) is mounted in the bearing sub-seat (2). Multiple bolt holes (12) are formed in the bearing main seat (1). Bolt through holes (22) matched with the bolt holes (12) in position and number are formed in the bearing sub-seat (2). Compared with the prior art, the split paper drawing roller bearing seat has the advantages of convenience indisassembly, stable structure and the like.

Description

technical field [0001] The invention relates to the field of paper towel processing machines, in particular to a split-type paper pulling roller bearing seat. Background technique [0002] At present, the paper machine drawing roll bearing housings are all welded, which is composed of a cylindrical bearing housing and a rectangular mounting base plate welded together. As it is a welded part, the material is Q235 with good welding performance. However, in the actual use process, the bearing seat and the bearing often wear and loosen. Because it affects the normal operation of the equipment, it can only be shut down for maintenance. During maintenance, the entire bearing seat must be disassembled. Under the circumstances, replace the spare parts of the bearing seat prepared in advance, which will increase the replacement cost and cause unnecessary waste. Contents of the invention [0003] The object of the present invention is to provide a split-type drawing roller bearing ...
