Description
Technical field
The utility model relates to a kind of bearing means, in particular, relates to a kind of self-aligning robot anti-friction bearing.
Background technique
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor.When other parts produce relative movement each other on axle, bearing is used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position, its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.Bearing is the important foundation component of all kinds of mechanized equipment, and its precision, performance, life and reliability play conclusive effect to the precision of main frame, performance, life and reliability.
Common rolling bearing, at confined space, moist and unlubricated, high-mechanic, under the specific work environments of HI high impact, common steel sleeve gets rusty easily, and can not work under unlubricated condition.If in use lubrication oil supply is not enough, bearing running hot can be caused, kill and even scrap, affect the working life of machine.
Model utility content
The utility model for the deficiency of existing product, and provide a kind of rational in infrastructure, practical, not easily get rusty while there is a kind of self-aligning robot anti-friction bearing of high tenacity.
A kind of self-aligning robot of the present utility model anti-friction bearing, described anti-friction bearing comprises outer ring, inner ring, retainer and roller, inside, described outer ring is provided with inner ring, described inner ring is provided with two row's raceways, arrange raceway edge at inner ring two and be provided with three protruding ribs, protruding rib two sides described in centre is respectively provided with an oil storage tank, respectively there is an oil storage tank inner side of the protruding rib described in both sides, arc ball mouth is provided with near the end of described inner ring, retainer is provided with between inner ring and outer ring, described roller is arranged in retainer pocket hole, described outer peripheral surface is inlaid with wear-resisting graphite alloy particle, described outer ring offers multiple oilhole, the mounting point of the corresponding oil storage tank of described oilhole.
Preferably, described outer ring adopts the one in middle-carbon steel, high carbon steel or chromansil steel to make.
Preferably, described outer ring is made up of steel for carburizing, and Carburization Treatment is carried out on surface, and surface hardness is 68HRC ~ 70HRC, and inner hardness is 50HRC ~ 58HRC.
Preferably, the surface spraying of described inner ring has curing molybdenum layer.
Preferably, the ring solid forging that described inner ring and outer ring are cut into by numerical control plasma cutting machine forms.
The beneficial effects of the utility model are: 1, adopt steel for carburizing manufacture, Carburization Treatment is carried out on surface, makes bearing heart portion softer, and surface is comparatively hard, therefore has stronger shock-resistant ability, and has higher wear resistance; 2, solid forging is compared common cast bearing wear resistance and is improved 1 times, fracture toughness improves more than 2 times, can meet compared with usage requirement under rugged environment and stressed complicated state, and cost of material is increased less than 30%, face checking situation is prevented while there is toughness, avoid and cast the stress point that causes and concentrate situation, effectively improve bearing intensity and rigidity; 3, molybdenum disulfide spraying is adopted to form.The object of lubricating layer is the greasy property strengthening sleeve lining further, axle sleeve and axle effectively can be lubricated in running-in period, can not damage raceway.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: outer ring 1, inner ring 2, retainer 3, roller 4, oilhole 5, protruding rib 6, oil storage tank 7, arc ball mouth 8.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
Embodiment 1
In the drawings, a kind of self-aligning robot of the present utility model anti-friction bearing forms primarily of outer ring 1, inner ring 2, retainer 3, roller 4, oilhole 5, protruding rib 6, oil storage tank 7, arc ball mouth 8.
Described anti-friction bearing comprises outer ring 1, inner ring 2, retainer 3 and roller 4, inside, described outer ring 1 is provided with inner ring 2, described inner ring 2 is provided with two row's raceways, three protruding ribs 6 are provided with at inner ring 2 liang row raceway edge, protruding rib 6 two sides described in centre is respectively provided with an oil storage tank 7, respectively there is an oil storage tank 7 inner side of the protruding rib 6 described in both sides, arc ball mouth 8 is provided with near the end of described inner ring 2, retainer 3 is provided with between inner ring 2 and outer ring 1, described roller 4 is arranged in retainer 3 pocket hole, described outer ring 1 surface inserting has wear-resisting graphite alloy particle, described outer ring 1 offers multiple oilhole 5, the mounting point of the corresponding oil storage tank 7 of described oilhole 5.
Embodiment 2
With embodiment 1 unlike; Described outer ring 1 adopts the one in middle-carbon steel, high carbon steel or chromansil steel to make.Described outer ring 1 is made up of steel for carburizing, and Carburization Treatment is carried out on surface, and surface hardness is 68HRC ~ 70HRC, and inner hardness is 50HRC ~ 58HRC.Employing steel for carburizing manufactures, and Carburization Treatment is carried out on surface, makes bearing heart portion softer, and surface is comparatively hard, therefore has stronger shock-resistant ability, and has higher wear resistance.
