Abstract
The utility model relates to a land preparation machine, and belongs to an improved bearing structure of the land preparation machine, particularly to an external spherical sealing bearing with a block for a soil shredder and a jolt-squeeze device of the land preparation machine. The external spherical sealing bearing is mounted in a bearing block in a matching manner; the outer spherical wall of a bearing outer ring is matched with an inner spherical wall of a block hole of the bearing block; a dual-layer framework type oil seal is mounted in the block hole of the bearing block outside the bearing; a first-layer framework type oil seal is mounted on the outer cylindrical surface outside the bearing inner ring in a matching manner; a second-layer framework type oil seal is mounted in the shaft diameter of a long shaft in an interference fit manner; an oil nipple is mounted in a through hole of a bearing block casing in a clearance between the outer end face of the bearing outer ring and the inner end face of the first-layer framework type oil seal; a side cover is arranged between the outer ring and the inner ring at the inner end of the bearing; the end face on the excircle of the side cover is fixedly connected with the outer ring of the bearing; and the end face on the inner circle of the side cover is movably matched with the inner ring of the bearing. The utility model has the advantages of reasonable and compact structure, convenience in installation, favorable sealing property, function of automatically aligning and long service life; and the external spherical sealing bearing with the block is especially suitable for agricultural machines which have great windability due to long shaft and can work in severe conditions.
Description
Technical field
The utility model relates to scarification equipment, belongs to the improvement of scarification equipment bearing structure, the particularly a kind of soil preparation machine clod-crusher and the device outer spherical surface stuffing box bearing of usheing to seat that jolt-squeezes.
Background technique
At present, the soil preparation machine clod-crusher and the device that jolt-squeezes be mainly used in after the ploughing hack pacifically, the soil preparation machine clod-crusher and the device rotary supporting part position design of jolt-squeezing are at two ends, sprue base+deep groove ball bearing structure is adopted in the rotary supporting part position.Because the agricultural machinery clod-crusher and the device that jolt-squeezes are mainly used in whole ground, use on the level land, in the open, in many dirt, humidity and the filthy environment or underwater work, Environmental Conditions is more abominable, domestic this kind farm machinery exists bearing short working life always at present, change frequent situation, seriously restricted the utilization efficiency and the high problem of maintenance cost of agricultural machinery.
Bear about shaft length 1.7-1.8m in the middle of the clod-crusher and the device that jolt-squeezes,,, produce unbalance loading and cause damage of bearings because original structure radial bearing aligning angle is very little owing to can produce bending at work.
Summary of the invention
The purpose of this utility model is to provide a kind of soil preparation machine clod-crusher and jolt-squeezes the device outer spherical surface stuffing box bearing of usheing to seat, it is rational in infrastructure, compact, easy for installation, good seal performance has the function of self-aligning, long service life, be particularly suitable for because axial length and winding degree is big, the farm machinery of working under mal-condition.
The purpose of this utility model is achieved in that a kind of soil preparation machine clod-crusher and jolt-squeezes the device outer spherical surface stuffing box bearing of usheing to seat, in bearing support, cooperate the bearing with spherical outside surface of usheing to seat is installed, the sphere outer wall of bearing outer ring matches with the sphere inwall in bearing support seat hole, in the seat hole of the bearing support outside bearing double-deck skeleton oil sealing is housed, wherein: on the external cylindrical surface in the bearing inner race outside, cooperate the skeleton oil sealing of first layer is installed, interference fit is installed with the skeleton oil sealing of the second layer on the major axis diameter of axle, on the through hole of the bearing support housing in gap between bearing outer ring exterior edge face and the skeleton oil sealing interior edge face of first layer, pump nozzle is installed, between the outer ring of bearing the inner and inner ring, side cover is being set, wherein side cover cylindrical end face is fixed on the bearing outer ring, and the interior nose circle face of side cover and the inner ring of bearing are movingly.
The utility model adopts the bearing with spherical outside surface of usheing to seat, and has self-aligning, easy for installation.In order to guarantee the working life of special bearing, adopted novel sealing structure that it is protected, double-deck skeleton oil sealing is housed to strengthen whole sealing effect in the bearing outside; The outermost outside framework oil seal is installed in bearing support inside, and endoporus contacts with major axis and guarantees sealing, in order to improve intensity, is specifically designed as special web frame oil sealing, and inner steel plate requires to adopt and adds Plate Steel to improve the outside framework oil seal integral rigidity.Another outside framework oil seal endoporus contacts with the bearing inner race external diameter surface, utilizes the high characteristics of bearing inner race machining accuracy and roughness, has strengthened the bearing seal performance.Skeleton oil sealing because the oil sealing internal diameter size is littler than axle journal, has certain magnitude of interference, and oil sealing is contained in after axle goes up, and the contractile force of the pressure of its cutting edge and self-tightening spring produces certain power of radially holding tightly to seal shaft, and the gap is revealed in blocking, reaches the purpose of sealing.The oil sealing mounting point is little simultaneously, axial dimension is little, compact structure, good seal performance, long service life.
Seal ring has been installed in the bearing with spherical outside surface bottom surface, and bearing has been played seal action.Guarantee the inner oil sealing life-span.This class bearing is specially adapted to work under mal-condition, can improve the working life of bearing greatly.
Therefore, the utility model is rational in infrastructure, and compactness is easy for installation, and good seal performance has the function of self-aligning, and long service life is particularly suitable for because axial length and winding degree is big, the farm machinery of working under mal-condition.
