Abstract
The utility model discloses a rotary cultivator bearing, include by inner circle and outer lane, be equipped with the rolling element between inner circle and the outer lane, characterized by: outer lane one end an organic whole is provided with outside bellied annular flange, is equipped with a plurality of mounting holes that are used for the installation to plough the sword on the annular flange. This scheme provides a rotary cultivator bearing, through improving bearing inner race, improves the anti stiff dough impact capacity of bearing, makes the bearing whole compact, long service life.
Description
Technical field
The utility model relates to a kind of rotary cultivator bearing, belongs to field of bearings.
Background technique
Rotary cultivator is widely used in farm machinery, effectively improves ploughing capacity.Arrange the discoid cultivated cutter plowed bottom rotary cultivator, cultivated swivel moves the effect playing renovation soil.When cultivated cutter touches the hard object such as stone in the process of digging, very violent to the feedback force of bearing, testing by loading capability proposition therefore to bearing.Fixing and mounting bracket outside traditional bearing, connected by scaffold and plough cutter, therefore need the Internal and external cycle to bearing, scaffold three keeps closely cooperating preferably, difficulty of processing, life-span and impact resistance are weak.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of rotary cultivator bearing, by improving bearing outer ring, improving the anti-stiff dough impact capacity of bearing, making bearing integral compact, long service life.
For achieving the above object, the utility model provides following technological scheme: a kind of rotary cultivator bearing, comprise by inner ring and outer ring, rolling element is provided with between inner ring and outer ring, one end, described outer ring is wholely set the annular flange flange of outwardly convex, and annular flange flange is provided with some mounting holes for installing cultivated cutter.
Preferably, described outer ring outer surface is conical surface, and outer ring outer surface outwards encloses the other end by convex annular acies and shrinks.
Preferably, the end face that described outer ring is positioned at annular flange flange one end is provided with ring-shaped depression, is combined with 0 type circle in ring-shaped depression.
Preferably, described outer ring and annular flange surface distribution are coated with zinc-nickel alloy layer.
By adopting technique scheme, being used for cultivated cutter is installed owing to being provided with annular flange flange on outer ring, avoiding the trouble coordinating a scaffold on outer ring again, make bearing integral structure compacter, annular flange flange integrally can process with outer ring, and intensity is good, strong by load-carrying ability.Owing to decreasing parts, make the overall impact resistance grow of bearing, working life extends.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model;
Fig. 2 is side view of the present utility model.
Accompanying drawing illustrates: 1, outer ring; 2, inner ring; 3, annular flange flange; 4, mounting hole; 5, ring-shaped depression; 6,0 type circle; 7, rolling element.
Embodiment
A kind of rotary cultivator bearing, comprise by inner ring 2 and outer ring 1, be provided with rolling element 7 between inner ring 2 and outer ring 1, one end, described outer ring 1 is wholely set the annular flange flange 3 of outwardly convex, and annular flange flange 3 is provided with some mounting holes 4 for installing cultivated cutter.Be used for installing cultivated cutter owing to being provided with annular flange flange 3 on outer ring 1, avoid the trouble coordinating a scaffold on outer ring 1 again, make bearing integral structure compacter, annular flange flange 3 integrally can process with outer ring 1, and intensity is good, strong by load-carrying ability.Owing to decreasing parts, make the overall impact resistance grow of bearing, working life extends.
Wherein, outer ring 1 outer surface is conical surface, and outer ring 1 outer surface is shunk to outer ring 1 the other end by annular flange flange 3 end.Due to annular flange flange 3 installation is cultivated cutter, stressed the strongest herein, easily there is the problem of Joint failure between annular flange flange 3 and outer ring 1, or there is the dangerous situations such as crackle, therefore outer ring 1 wall thickness herein should do thick point, but due to the cooperation of outer ring 1 inwall is rolling element 7, internal surface needs to do according to standard, therefore outer ring 1 outer surface can only be made conical surface.
Wherein, the end face that outer ring 1 is positioned at annular flange flange 3 one end is provided with ring-shaped depression 5, is combined with 0 type circle 6 in ring-shaped depression 5.The dust, the weeds that arrange external world when 0 type circle 6 can avoid cultivated cutter to plow herein enter Bearing inner, play dust-proof effect.
Wherein, outer ring 1 and annular flange flange 3 surface distributed are coated with zinc-nickel alloy layer.Due to rotary cultivator bearing working circumstance complication, need to carry out effective antirust treatment to bearing outer ring 1, zinc-nickel alloy layer has excellent antirust ability.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
