Abstract
The invention provides a hydraulic plunger pump sliding bearing and a machining method of the hydraulic plunger pump sliding bearing, belonging to the technical field of the machining of a bearing. The bearing comprises a bearing neck and a bearing pad cooperatively installed with the bearing neck, wherein the bearing pad takes a corrosion-resistant alloy as a base body (1), and the inner surface of the base body (1) is injected with corrosion-resistant engineering plastics (2); at least one radial hole (1.1) is formed in the base body (1), and the side face of the base body (1) is provided with a ring-shaped groove (1.2); and the middle of the corrosion-resistant engineering plastics (2) which is injected at the inner surface is provided with a ring-shaped water through groove (2.2) which is convenient for water to pass and is used for lubricating and cooling the bearing, and the internal periphery is evenly provided with at least one axial water through groove (2.1). According to the hydraulic plunger pump sliding bearing and the machining method of the hydraulic plunger pump sliding bearing provided by the invention, the structure of a hydraulic pump can be simplified, so that the hydraulic pump is longer in service life.
Description
Technical field
The present invention relates to a kind of water pressure plunger pump sliding bearing and processing method thereof, belong to technical field of bearing processing.
Background technique
Water Hydraulic Pump is the core drive element in the water hydraulic system.Every country is all being made great efforts exploitation sea water and fresh water hydraulic element now, and the Water Hydraulic Pump of having researched and developed mainly contains the structural types such as gear type, blade type and plunger type.Because the engagement of the line higher pair of gear pump makes the contact gear ratio merit very large, vane pump is more responsive to the damage ratio of medium, structure also more complicated and sealing effect poor; Plunger pump has that compact structure, quality are light, the working pressure high, and the ratio merit of vital part is little more a lot of than the pump of other types under identical operating conditions.So the structural type of plunger type is applicable in oil hydraulic pump take sea water and fresh water as working medium, the seawater hydraulic pump developed of domestic and international many units has all adopted plunger-type structure at present.Can be divided into inclined disc type and the large class of clino-axis type two by the structural type plunger pump.General inclined shaft pump adopts connecting rod to stir the plunger actuation movement of cylinder block and completes flow work, impact so all will bear the very high bar that changes of frequency at the time inner plunger in every one week of rotation of cylinder body and connecting rod, this impact is not only very unfavorable to the abrasion condition of trunk piston set but also have a very large operational noise.Comparatively speaking, the swash plate pump Comparision is steady, and noise ratio is lower.
Swash plate pump is rotated cylinder body, is critical component to the spring bearing of cylinder body, and the bearing in the mineral oil pump generally adopts the oil lubrication roller bearing.In water pump, have and also use roller bearing in high-pressure water pump, in pump inside with water and oil pocket separately, complicated structure.Fully water lubricating bearing directly water guarantees the normal use of bearing, and is simple in structure, easy to use.
Summary of the invention
The object of the present invention is to provide a kind of sliding bearing and processing method thereof of suitable water hydraulic plunger pump, make processing cost low, simple in structure.
A kind of sliding bearing of suitable water hydraulic plunger pump comprises that axle journal and axle journal coordinate the bearing shell of installing, and described bearing shell adopts corrosion resisting alloy to do matrix 1, at matrix 1 internal surface injection moulding Wear-resistant engineering plastic 2; Have more than one radial hole 1.1 on matrix 1, the side has annular groove 1.2; Have at the middle part of the Wear-resistant engineering plastic 2 of internal surface injection moulding and be convenient to the lubricated and annular water-flowing trough 2.2 that dispels the heat that water flowing is used for bearing, be evenly equipped with more than one axial water-flowing trough 2.1 in inside circumference.
the processing method of the sliding bearing of described a kind of suitable water hydraulic plunger pump, axle journal roughing is by Overheating Treatment, make hardness meet the requirements of hardness, the correct grinding axle journal, according to journal size, matching gap, the Rational Thickness of the engineering plastic bed of material, determine the bearing shell size, adopt corrosion resisting alloy to do matrix 1, at matrix 1 internal surface injection moulding Wear-resistant engineering plastic 2, have some radial holes 1.1 on the matrix 1 of bearing shell, the side has annular groove 1.2, bearing shell processes more than one annular water-flowing trough 2.2 at the middle part after injection moulding, be processed with more than one axial water-flowing trough 2.1 inside circumference is uniform, be convenient to the lubricated and heat radiation that water flowing is used for bearing.
This a kind of water pressure plunger pump sliding bearing of the present invention and processing method thereof can be simplified the water hydraulic pump structure, make Water Hydraulic Pump can have more can be high working life.
