Description

Novel guide bearing butt joint device

Technical Field

The utility model relates to the technical field of guide bearings, in particular to a novel guide bearing butt joint device.

Background

The guide bearing is used as an important support part of the vertical pump, and in order to ensure that the unit operates stably, the guide bearing with a larger long diameter ratio is widely used as the support part of the vertical pump, in particular to a slender long shaft pump.

Because of the production process and material characteristics of part of the lining material of the guide bearing, the length-diameter ratio of the raw material cannot meet the requirements of unit use. In the past, two or more sections of bearing lining material were loaded into the bearing substrate, and each section of lining was positioned by driving screws into the substrate at the corresponding location. However, the number of the holes punched is too large, so that the production difficulty is increased, and the rigidity of the bearing matrix is reduced; and when the holes are too many, the lining is easy to be jacked to the bulge, so that the phenomenon of non-roundness inside the bearing is caused. Aiming at the situation, technical innovation is carried out on the basis of the existing product.

In the figure: 1. a bearing substrate; 2. a barrel; 3. flanging; 4. a first liner; 5. a second liner; 6. a groove; 7. notching; 8. a pin; 9. a shaft body; 10. a jack; 11. a slot; 12. and (4) screws.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides the following technical solutions: the utility model provides a novel lead bearing butt joint device, including bearing base member 1, bearing base member 1 comprises opening barrel 2 left and turn-ups 3 that are located barrel 2, be equipped with first inside lining 4 and second inside lining 5 in the barrel 2, the left end face of first inside lining 4 and the right-hand member face of second inside lining 5 all are equipped with a recess 6, two 6 butt joints of recess form a scarce groove 7, be equipped with pin 8 in the scarce groove 7, still include axis body 9, axis body 9 is located the inside of first inside lining 4 and second inside lining 5, the surface of axis body 9 and the inner wall laminating of first inside lining 4 and second inside lining 5.

Be equipped with jack 10 on the second inside lining 5, be equipped with the slot 11 that runs through the section of thick bamboo wall on the barrel 2, the vertical central line collineation of jack 10 and slot 11, the inner wall of slot 11 and jack 10 is the helicitic texture, installs screw 12 on the barrel 2, and screw 12 passes jack 10, and the lower extreme of screw 12 is arranged in jack 10, and screw 12 links to each other with jack 10 and slot 11 screw, and the convenience is to the dismantlement of inside lining.
