Abstract
The utility model relates to an internally-threaded oil lubrication rod end joint bearing with a larger swinging angle. The internally-threaded oil lubrication rod end joint bearing with the larger swinging angle is provided with an oil and grease dual-lubrication system, has the larger swinging angle, and is higher in impact resistance and long in service life. The joint bearing comprises a bearing rod end body and a bearing rod, wherein an inner circle and an outer circle of the joint bearing are arranged in the bearing rod end body. A structural key point is that the inner circle has an outer spherical surface; the outer circle has an inner spherical surface; the inner and outer circles are integrally assembled at a swinging angle of more than 15 degrees; an inner circle inner oil groove, an inner circle outer oil groove and an inner circle oil hole for connecting the inner circle inner oil groove with the inner circle outer oil groove are formed in the inner circle; an outer circle oil hole and an outer circle oil groove are formed in the outer circle; the inner circle oil hole is communicated with the outer circle oil hole; an oil nipple communicated with the working surfaces of the inner and outer circles is also formed in the bearing rod end body; a threaded hole is formed in the bearing rod.
Description
Technical field
The utility model relates to a kind of internal thread oil lubrication spherical plain bearing rod end for cylinder, oil cylinder, lathe, steamer, space equipment, especially more big swing angle internal thread oil lubrication spherical plain bearing rod end.
Background technique
Oil lubrication spherical plain bearing rod end pivot angle is in the market conventionally all below 14 degree, and aperture at its pivot angle majority of spherical plain bearing rod end of the above heavy load of 30mm all within the scope of 7 degree, limit to a great extent and needed the more user demand of big swing angle manufacturer, their product specification manufacture is restricted.Oil lubrication spherical plain bearing rod end outer ring is commonly metal natural hardness, because production technology and assembly method problem can not heat-treat, so that Wear Resistance, impact resistance are very poor.Due to the restriction of manufacturing technique method, the height of Internal and external cycle, can not do greatly, in having limited pendulum angle, has more limited load-carrying properties.Because spherical plain bearing rod end does not have lubrication system, easily wear and tear, affect product working life.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of and has oil, fat double-lubrication system, can realize big swing angle, the more big swing angle internal thread oil lubrication spherical plain bearing rod end of more shock-resistant, long service life.
For achieving the above object, the utility model adopts following scheme, the utility model comprises bearing rod end body, bearing rod, inner ring and the outer ring of joint shaft bearing are set in bearing rod end body, its structure outline is that inner ring has outer spherical surface, outer ring has inner ball surface, both are pendulum angle and are greater than 15 degree assembling one, on inner ring, be provided with inner ring inner oil sump, inner ring outer oil sump, connect the inner ring oilhole of inner ring inner oil sump and inner ring outer oil sump, on outer ring, be provided with outer ring oilhole, outer ring oil groove, inner ring oilhole communicates with outer ring oilhole, on bearing rod end body, be also provided with and inner ring, the oil nozzle that outer ring working surface communicates, in bearing rod, be provided with tapped hole.
model utility beneficial effect
The utility model adopts the inner ring of joint shaft bearing larger than outer ring height, make joint shaft bearing there is larger swing ratio, can produce larger pendulum angle, thereby make product there is larger pivot angle than existing product, overcome common product and can not carry out the large difficulty of producing than design that swings, make all product pivot angles all be greater than 15 degree, maximum pivot angle can reach 22 degree; On the inner ring of spherical plain bearing rod end, outer ring, all put oil groove, oilhole, realize joint shaft bearing oil lubrication by oilhole to lubricating oil filling in oil groove; Injecting grease by oil nozzle reaches working surface and realizes grease lubrication; Adopt lubricant oil, the dual lubricated wearing and tearing that can greatly reduce joint shaft bearing of lubricant grease, wear resistance improves more than 50% than existing product, has extended the working life of product.The slip surface of inner ring, outer ring has all carried out phosphatization processing, and slip surface is produced as spongiform phosphating coat, energy adsorpting lubrication grease, thus further improve life of product.The design of increasing of outer ring height dimension is applied with quenching technical, in increasing product load-carrying properties, has improved greatly the impact resistance of product, has generally solved the not impact-resistant problem of existing product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the I place partial enlarged drawing of Fig. 1.
embodiment
As shown in the figure, the utility model comprises bearing rod end body 1, bearing rod 4, be arranged on inner ring 6 and the outer ring 7 of the joint shaft bearing 3 in bearing rod end body 1, inner ring 6 has outer spherical surface, outer ring 7 has inner ball surface, both are pendulum angle and are greater than 15 degree assembling one, in inner ring 6, outer surface is respectively arranged with inner ring inner oil sump 9, inner ring outer oil sump 11, connect the inner ring oilhole 10 of inner ring inner oil sump 9 and inner ring outer oil sump 11, on outer ring 7, be provided with outer ring oilhole 12, outer ring oil groove 13, inner ring oilhole 10 communicates with outer ring oilhole 12, on bearing rod end body 1, be also provided with and inner ring 6, the oil nozzle 8 that outer ring 7 working surfaces communicate, in bearing rod 4, be provided with tapped hole 5.
Maximum pendulum angle α of the present utility model is 22 degree.Also be provided with seal ring 2 at inner ring 6 near the outer of outer ring 7, prevent that lubricant oil, grease from leaking and the carrying out of dust.Seal ring 2 can be matched according to bearing, has further improved anti-dust performance.The inside and outside surface of inner ring 6 and outer ring 7 be through phosphatization processing, make their surfaces have one deck meagre as spongiform phosphatization nethike embrane, can adsorpting lubrication oil, put forward greasy property, increase the service life.Bearing rod end body 1 and bearing rod 4 adopt material to forge or casting, therefore have higher utilization ratio and manufacturing efficiency, forge and make product have good mechanical property, and the more existing same model product of impact resistance improves more than 2 to 6 times.Bearing rod end body 1 and bearing rod 4 are electroplated, are sprayed paint etc. and refill and join inner ring outer ring 3 after surface treatment, and surface-treated layer has rust inhibition, has improved product aesthetic measure simultaneously.
