Description
Technical field
The utility model relates to agriculture scarification equipment, belongs to the rake selfaligning bearing seat assembly on blade formula combined working soil machinery.
Background technique
Along with the raising of agrotechnical level, tend to large plot Planting Crops, so more be conducive to unified management, more effectively utilize land resources, along with the requirement of agricultural planting large size, the power of its tillage machinery is also large-scale rapidly, high pass filter, the farmland operation power of 200-350 horsepower has spread to each multi-form agriculture operation area, but in the equalization system of land for growing field crops, ploughing of farm machinery, whole, kind, results all maximize accordingly, this must be to mechanical job requirements, the requirement manufacturing and designing of facility has been launched to a brand-new problem, the design strength and the structure that are the desired workpiece of large farm machinery cannot be continued to use in the past less facility pattern again, this just needs innovation to be applicable to the agricultural machinery and implement of large-sized power mechanical work.
Although blade fixed bearing block used on existing blade formula combined soil preparing machine is through improving several times, but fundamentally do not solve yet the function of the comprehensive aligning of bearing energy, in the time raking the soil level, bearing support contacts with soil, if bearing can not aligning, just cannot just really accomplish the sealing to bearing, existing model utility a kind of harrows and solved the unreliable of bearing seal, really this difficult problem of aligning with selfaligning bearing seat assembly.
Model utility content
The purpose of this utility model is to provide a kind of rake to use selfaligning bearing seat assembly, and it is rational in infrastructure, can increase the aligning scope of bearing, adapts to the need of work of the combined soil preparing machine of large field operation, bearing seal reliable performance, long service life.
The purpose of this utility model is achieved in that a kind of rake selfaligning bearing seat assembly, be included between the length with ladder platform on pipe, coordinate be successively installed with outer spherical surface selfaligning bearing and short between pipe, ladder platform by pipe between length and short between the interior edge face of pipe by the inner ring location of outer spherical surface selfaligning bearing, being positioned at jump ring that between the length of short pipe outer end, pipe is installed by draw-in groove will short manage and locks, the cooperation of outer spherical surface selfaligning bearing is arranged in the bearing support with interior concave spherical surface, be positioned between the length of outer spherical surface selfaligning bearing both sides pipe and short between two symmetrical aligning guide pin bushings are installed respectively on pipe, the outer spherical surface diameter of two aligning guide pin bushings equates with the spherical diameter of outer spherical surface self-aligning bearing outer ring, its sphere being integrally formed matches with the sphere of bearing support inwall indent, bearing support is fixed on blade bearing spider by bolt.
Between length of the present utility model, pipe, short pipe therebetween are pinned an outer spherical surface selfaligning bearing, lock by jump ring, become an entirety, and like this, a pipe just becomes one to rotate entirety with the interior steel bowl-type of outer spherical surface selfaligning bearing; Comprise by boss inner ball surface cartridge housing and concave station inner ball surface cartridge housing equippedly, the inner ball surface of two spherical bearing block half shells matched, and match in the outer spherical surface of spherical self-aligning bearing, between realization pipe assembly can be in cartridge housing comprehensive aligning; Be included in spherical bearing both sides installings aligning guide pin bushing, the inner ball surface of the sphere of aligning guide pin bushing and left and right half shell of inner ball surface bearing support is slidably matched, the endoporus of aligning guide pin bushing with grow between manage, short between ligament coordinate, and with butter as lubricant medium; Because aligning guide pin bushing is retrained by protruding, recessed inner ball surface bearing support shell, can only synchronize with spherical self-aligning bearing and do around a rotation around aligning central point; Can be with bearing synchronous aligning thereby realize aligning guide pin bushing, aligning guide pin bushing coordinates with the cylinder surface of revolution formation concentric gap on a pipe simultaneously, and in a pipe and outer spherical surface selfaligning bearing, steel bowl can only rotate around its central shaft; Between having realized, pipe, bearing, when self rotates, do around the heart and rotate with aligning center, realize aligning function; Be provided with interior oil seal water wing and outer dust-proof seal ring at the endoporus place of aligning guide pin bushing; to increase lubricating grease pressure in chamber; and isolated extraneous dust impouring; and oiling is set on aligning guide pin bushing chews and while being convenient to maintain, inject lubricating grease; ensure that each moving element forms oil film protection, is fixed on blade bearing spider by fixing bolt.
The utility model is rational in infrastructure, has increased the aligning scope of bearing, has adapted to the combined soil preparing machine requirements of one's work of large field operation, and bearing seal performance is good, long service life.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is main TV structure schematic diagram of the present utility model, the A-A sectional structure schematic diagram that Fig. 2 is Fig. 1.
