Abstract
The invention belongs to the technical field of self-aligning roller bearings for roller presses and specifically relates to a self-aligning roller bearing for a retainer compound guiding large cement roller press. The self-aligning roller bearing is characterized by a compound guiding form of using two retainers for a roller and an inner ring, wherein inner and outer diameters of each retainer both are designed into a structure with a large inclination angle and each end face of the retainer is designed with a slope; a pocket crescent slot is formed in an inner surface of a pocket of each retainer and inner diameter crescent slots are evenly distributed at an inner diameter lug boss of the retainer; and the retainers are made of nodular cast iron. The self-aligning roller bearing for the retainer compound guiding large cement roller press has the advantages that the defects such as non-smooth lubrication, high friction and the like of the bearing are improved from multiple angles, the weight of each retainer is reduced from structure and material, and therefore, the friction is reduced and the service life of the bearing is prolonged.
Description
Technical field
The invention belongs to large-scale cement roll squeezer selfaligning roller bearing technical field, be specifically related to retainer compound guiding large-scale cement roll squeezer selfaligning roller bearing.
Background technique
Roll squeezer carries out roll-in crushed work mainly for large-scale ore, be the first-class operation of cement processing, and the Assembly And Disassembly of large-scale roller press is very difficult, and bearing quality directly affects the roll squeezer operation cycle, thus affects the processing of subsequent handling.
Current middle-size and small-size roll squeezer bearing generally adopts grease lubrication mode, retainer is that inner ring guides, the part break flour of wearing and tearing mixes mutually with lubricating grease and causes oiling agent actual effect very fast, large-scale roller press bearing then have employed circulating oil lubrication, and retainer weares and teares, the break flour dropped can assemble clogged oil line gradually with fluid.In addition, large size bearing weight issue has also increased the weight of the wearing and tearing of retainer.
Summary of the invention
Object of the present invention overcomes above-mentioned deficiency exactly, provides a kind of retainer compound guiding large-scale cement roll squeezer selfaligning roller bearing.
The technical solution adopted for the present invention to solve the technical problems is: retainer compound guiding large-scale cement roll squeezer selfaligning roller bearing, comprise outer ring 1, retainer 2, rolling element 3 and inner ring 4, it is characterized in that, two panels retainer 2 is adopted to be rolling element 3 and inner ring 4 compound guiding form, retainer 2 internal-and external diameter all adopts large tilt angle structure, retainer 2 end face adopts slope design, be provided with pocket hole crescent 5 at the pocket internal surface of hole of each retainer 2, at retainer 2 internal diameter boss, place is provided with equally distributed internal diameter crescent 6.
Retainer 2 adopts spheroidal graphite cast iron, and with self-lubricating property, material density is little, and quality is light.Retainer 2 internal-and external diameter all adopts large tilt angle structure, increases the area of contact with rolling element 3, increases stress surface.Adopt the mode of rolling element 3 and inner ring 4 compound guiding, take into account rolling element 3 and transship the problem that viscous motion and retainer 2 wear and tear.Be that rolling element 3 guides when bringing into use, consider the factor such as to wear and tear in rolling element 3 and pocket hole, guide along with use gradually becomes inner ring 4.
The invention has the beneficial effects as follows, two panels retainer is adopted to be rolling element and inner ring compound guiding form, improve in multiple angle that lubrication is smooth, rub the shortcoming such as large, select spheroidal graphite cast iron Raw material processing, and reduce retainer total quality from structure, thus reduce friction, improve the working life of bearing.
Below in conjunction with drawings and Examples, the invention will be further described.

Embodiment
See Fig. 1-4, the retainer compound guiding large-scale cement roll squeezer selfaligning roller bearing that the present invention proposes, comprise outer ring 1, retainer 2, rolling element 3 and inner ring 4, it is characterized in that, adopt two panels retainer 2 to be rolling element 3 and inner ring 4 compound guiding form, retainer 2 internal-and external diameter all adopts large tilt angle structure, and retainer 2 end face adopts slope design, be provided with pocket hole crescent 5 at the pocket internal surface of hole of each retainer 2, at retainer 2 internal diameter boss, place is provided with equally distributed internal diameter crescent 6.
Working procedure of the present invention:
During this bearing initial operation, retainer 2 guides for rolling element 3, by retainer 2 internal-and external diameter large tilt angle γ and β, increases rolling element 3 and the area of contact of retainer 2, alleviates the load of single rolling element 3.In bearing operation process, because retainer 2 adopts ductile cast iron material, material itself is with self lubricity, and lubrication strengthened by the large slope α and the pocket hole crescent 5 that add holder 2 end face, reduces rolling element 3 and the wearing and tearing of retainer 2 and the overload viscous motion of rolling element 3.Pocket hole crescent 5 can also play the effect storing oiling agent and get rid of abrasive dust.
When after bearing long time running, rub between retainer 2 and rolling element 3 and distortion acquires a certain degree time, retainer 2 deflection strengthens, its internal diameter boss and inner ring 4 centre rib gap reduce, the state of retainer 2 gradually becomes rolling element 3 and jointly guides (or inner ring 4 guides) with inner ring 4, by the internal diameter crescent 6 at internal diameter boss place, stable lubricant film is formed between inner ring 4 centre rib and retainer 2 internal surface, reduce inner ring 4 and the friction of retainer 2, ensure the pivotal stability of bearing.
The present invention controls retainer 2 and the wear extent of rolling element 3 from structural design, protects the life cycle of the major part such as retainer 2 and rolling element 3 in Material selec-tion and lubricating condition largely, thus extends the working life of bearing.
