Abstract

A kind of drier oil rolling bearing structure improvement of installing for pump shaft of the utility model design, comprise bearing support, bearing, pump shaft, it is characterized in that: offer screw thread on the top of pump shaft, pump shaft front end is provided with bearing, the pump shaft of bearing outer side surface is set with thrust bush, the screw thread on the pump shaft top outside thrust bush is twisted and is connected to little round nut.The inner side surface of thrust bush is relative with the bearing outer side surface that pump shaft front end is installed.Described bearing is N309E roller bearing.The utility model has the advantages that new structure comparatively original structure, use the bearing of reduced size instead, can reduce purchase cost, bearing support size also can change little further, has saved material, and meanwhile, water pump outward appearance is more exquisite, attractive in appearance, more competitive; In addition, thrust bush size thickeies 8 millimeters, and intensity is strengthened, and the axial displacement of bearing reduces, and vibrations must weaken, and the reliability of water pump increases.Water pump safe operation is provided safeguard.

Description

A kind of novel drier oil rolling bearing structure improves
Technical field
The utility model relates to a kind of novel drier oil rolling bearing structure to be improved.
Background technique
Middle low-pressure boiler feed water pump (such as: DG85-45*9) uses 45 type drier oil roller bearing components, select this type roller bearing 10 of NU310E meeting GB/T 283-1994 standard, within it and a thrust shaft bearing sleeve 12 (as figure mono-) is housed between axle 11, the little round nut 13 of right-hand member is locked.This design improves purchase cost, has selected the bearing of larger number, has been unfavorable for reducing costs.Meanwhile, thrust shaft bearing sleeve is too thin, insufficient strength, and the water pump operation time one is long, easily shakes.Therefore urgently its mounting connection structure is improved.
Summary of the invention
The purpose of this utility model solves middle low-pressure boiler feed water pump in prior art to adopt thrust shaft bearing sleeve and the problems referred to above existing for roundlet nut check pump shaft, provides a kind of novel drier oil rolling bearing structure to improve.A kind of drier oil rolling bearing structure improvement of installing for pump shaft of the utility model design, comprise bearing support, bearing, pump shaft, it is characterized in that: offer screw thread on the top of pump shaft, pump shaft front end is provided with bearing, the pump shaft of bearing outer side surface is set with thrust bush, the screw thread on the pump shaft top outside thrust bush is twisted and is connected to little round nut.The inner side surface of thrust bush is relative with the bearing outer side surface that pump shaft front end is installed.Described bearing is N309E roller bearing.The utility model has the advantages that new structure comparatively original structure, use the bearing of reduced size instead, can reduce purchase cost, bearing support size also can change little further, has saved material, and meanwhile, water pump outward appearance is more exquisite, attractive in appearance, more competitive; In addition, thrust bush size thickeies 8 millimeters, and intensity is strengthened, and the axial displacement of bearing reduces, and vibrations must weaken, and the reliability of water pump increases.Water pump safe operation is provided safeguard.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the utility model is elaborated.
Accompanying drawing 1 is existing structure schematic diagram; Accompanying drawing 2 is structural representation of the present utility model.
Embodiment
A kind of drier oil rolling bearing structure improvement of installing for pump shaft in figure, comprise bearing support 1, bearing 2, pump shaft 3, it is characterized in that: offer screw thread on the top of pump shaft, pump shaft front end is provided with bearing, the pump shaft of bearing outer side surface is set with thrust bush 4, the screw thread on the pump shaft top outside thrust bush is twisted and is connected to little round nut 5.The inner side surface of thrust bush is relative with the bearing outer side surface that pump shaft front end is installed.Described bearing is N309E roller bearing.
Be for present case, the utility model is improved appropriately, to solve the problem.Through strength check, determine this type roller bearing of the N309E meeting GB/T 283-1994 standard of selection of small, on the right side of it, use thrust bush instead, right-hand member roundlet nut check.New structure is original structure comparatively, uses the bearing of reduced size instead, can reduce purchase cost, and bearing support size also can change little further, has saved material, and meanwhile, water pump outward appearance is more exquisite, attractive in appearance, more competitive; In addition, thrust bush size thickeies 8 millimeters, and intensity is strengthened, and the axial displacement of bearing reduces, and vibrations must weaken, and the reliability of water pump increases.Water pump safe operation is provided safeguard.
