Abstract

The utility model provides a novel lubricating bearing, and belongs to the technical field of machinery. The novel lubricating bearing is structured into two types; the novel lubricating bearing in type of a flat plate comprises an upper steel plate, a lower steel plate, a copper alloy plate, and an outer coating manufactured by a galvanizing steel plate; a concentric axle hole is formed; oil storing grooves with arc shaped or rectangular cross sections are processed on two planes of the copper alloy plate; the oil grooves integrally form a continuous regular and symmetric geometric figure in shape of a curved line or a cone or a rectangle or staggered ovals and the like; pock shaped oil storing pits are supplemented in blank parts on the planes of the copper alloy plate in order to form an oil storing lubricating plane in combination of points and lines; two to six through round holes are symmetrically distributed beside the oil grooves on two sides of the concentric axle hole; annular bosses are formed on one surfaces, contacted with the copper alloy plate, of the two steel plates along the side edges; the inside diameter of the bosses is the same as the outside diameter of the copper alloy plate, and the bosses and the copper alloy plate are in clearance fit; and the novel lubricating bearing in type of a bearing pad is formed in the way that the oil storing grooves and the oil storing pits are processed on the surface, and two to six through round holes are symmetrically distributed close to two end parts. The novel lubricating bearing has the characteristics of being good in lubricating effect and long in service life.

Description

A kind of Novel sliding bearing

Technical field

Belong to field of mechanical technique, relate to a kind of Novel sliding bearing.

Background technique

As the bearing of one of important accessory of machinery, its purposes wide, consumption is big, well-known more than the pattern kind.Traditional bearing mainly contains rolling bearing and sliding bearing, and tapered roller bearing, roller bearing, ball bearing, needle bearing, aligning series bearing, thrust series bearing, damping series bearing, self oiling bearing etc. are arranged in the rolling bearing.The characteristics of rolling bearing are that friction factor is low, and linear velocity is high, has realized standardization, and kind is many, can obtain less friction torque in larger parameter area.The sliding bearing kind is also a lot, can be divided into radially (centripetal) sliding bearing and thrust (axially) sliding bearing two classes by direction that can bearing load, and its structure is mainly bearing shell formula, flat and linear type.Sliding bearing has the bearing capacity height, and shock resistance is good, and stable working is reliable, the characteristics such as noise is little, and the life-span is long can obtain the function that rolling bearing can't be realized, the occasion that is suitable for high speed, heavy duty, impact, wearing and tearing, precision requirement height, long service life is used, and cost is low.Field and other industrial bearings such as it is widely used in that water power such as dam work arc door prop up that hinge holds and water turbine, accident door-hinge hold, metallurgical equipment and mining machinery, internal-combustion engine, rolling mill, section press bed, engineering machinery, conveyor track, automotive industry such as automobile chassis, large-size machine and instrument, radar, astronomical telescope.The plain bearing that uses at present exists the lubricant oil memory space of bearing lubrication face few, and service time is short, needs frequent charging-up lubricant oil, the shortcoming that wastes time and energy.Summary of the invention

The purpose of this utility model can be used time saving and energy saving sliding bearing after providing lubricant oil of a kind of filling for a long time.

The technological scheme that the utility model addresses the above problem is to comprise two kinds of structural types.

The first structural type is flat sliding bearing, and the overcoat of being made by two blocks of circular steel plates up and down, a middle circular copper alloy plate and galvanized steel plain sheet forms, and there is a concentric axis hole at their center.Have on two planes of certain thickness copper alloy plate, be processed into the oil storage tank that the transverse section is arc or rectangle, the integral body of oil groove forms one take curvilinerar figure or taper or rectangle or the staggered plane geometric figures as leading such as ellipse of continuous regular symmetry, be aided with pit shape store oil pit in the plane of copper alloy plate blank space, the store oil that formation point, toe-in close, lubricated face; By the oil groove of copper alloy plate planar central both sides, be distributed with symmetrically the circular hole of 2-6 two-sided perforation, so that the lubricant oil on copper alloy plate two sides replenishes mutually, keep balance.Two one sides that circular steel plate contacts with copper alloy plate, outer rim are processed into a circular boss, and the internal diameter of boss is identical with the external diameter of copper alloy plate, therebetween Spielpassung.The overcoat that they are made with a galvanized sheet metal carries out packaging protection.

The second structural type is bearing shell formula sliding bearing, be that surperficial or inside and outside surface Machining becomes the same oil storage tank of global shape and section configuration and flat sliding bearing and pit shape store oil pit within it, be symmetrically distributed with equally respectively the circular hole of 2-6 inside and outside perforation at the bearing shell that inside and outside two lubricated faces are arranged near the place of two ends.

Through using proof, the utlity model has the characteristics of high lubricating effect, long service life, the lubricant oil of annotating one time, under equal service condition, oiling can improve more than 2 times blanking time, and double above the working life of bearing.

Fig. 1 is oil groove on the copper alloy plate of the present utility model plane and pockmark shape, arrange schematic representation;

Fig. 2 is structural representation of the present utility model;

1-copper alloy plate, 11-oil storage tank, 12-pockmark, 13-through hole, the circular steel plate of 2-, 3-galvanized sheet metal among the figure.

Below in conjunction with embodiment and accompanying drawing the utility model is further described.

Embodiment 1

The copper alloy plate 1 of a thick 5-12mm is processed into circle, at circular axis hole of center portion processing, the diameter of axis hole is with identical with its supporting diameter of axle, two sides at copper alloy plate 1, being processed into respectively global shape is end to end polygon oil storage tank 11, the outside of taper oil storage tank 11 and ring-type oil storage tank 11 connect, the transverse section of oil storage tank 11 is circular arc, blank space in oil storage tank 11 both sides, irregular some separate pit shape semicircular recess 12 that distributing in the outside or the inboard of oil storage tank 11, are symmetrically distributed with two manhole 13(as shown in Figure 1), in order to the lubricant oil on copper alloy plate 1 two sides is replenished mutually, profit and loss keep balance.

Be that steel plate about 4mm is processed into circle with two thickness, circular axis hole (as shown in Figure 2) is processed at the center of steel plate 2, its diameter is greater than the diameter of copper alloy plate 1 axis hole, steel plate 2 is processed into a boss with the outer rim of copper alloy plate 1 contacted one side, the height 2-4mm of boss, the thickness of boss is 2-3mm, and the internal diameter of boss is identical with the external diameter of copper alloy plate 1, is Spielpassung between copper alloy plate 1 and the steel plate 2.Before the installation, the two sides of copper alloy plate 1 is coated with full lubricant grease, then is assemblied in one with two block plates 2, they are encapsulated in the protecting jacket that galvanized sheet metal 3 makes again, a cover sliding bearing namely assembles to be finished.
