Abstract
The utility model belongs to the pack roller special bearing of mulch film plastic film mulch equipment, particularly a kind of film spreading machine pack roller sealed bearing structure, with coordinating in the bearing hole of the circular shaft bearing of adpting flange, bearing with spherical outside surface is installed, coordinate in the concave station in the bearing block bearing hole on the right side of bearing with spherical outside surface and inner frame oil sealing and outer-frame oil seal are installed, wherein the endoporus of inner frame oil sealing matches with the inner ring external diameter of bearing with spherical outside surface, and the endoporus of outer-frame oil seal matches with the roll shaft external diameter being positioned at bearing support axis hole.The utility model compact structure, good seal performance, can improve lubricating condition, improves the working life of bearing, reduces the workload of maintenance.
Description
Technical field
The utility model belongs to the pack roller special bearing of mulch film plastic film mulch equipment, particularly a kind of film spreading machine pack roller sealed bearing structure.
Background technique
At present, film spreading machine is mainly used in the work of mulch film plastic film mulch, in equipment, the design of pack roller rotary support position is at two ends, rotary support position adopts rolling bearing units, the operation because agricultural machinery is main in the open, in many dirt, humidity and filthy environment, relatively badly, to there is bearing short for working life always for domestic this kind of farm machinery at present for Environmental Conditions, change frequent situation, seriously constrain the utilization efficiency of agricultural machinery and the high problem of maintenance cost.
Summary of the invention
The purpose of this utility model is to provide a kind of film spreading machine pack roller sealed bearing structure, its compact structure, and good seal performance, can improve lubricating condition, improves the working life of bearing, reduces the workload of maintenance.
The purpose of this utility model is achieved in that a kind of film spreading machine pack roller sealed bearing structure, with coordinating in the bearing hole of the circular shaft bearing of adpting flange, bearing with spherical outside surface is installed, coordinate in the concave station in the bearing block bearing hole on the right side of bearing with spherical outside surface and inner frame oil sealing and outer-frame oil seal are installed, wherein the endoporus of inner frame oil sealing matches with the inner ring external diameter of bearing with spherical outside surface, and the endoporus of outer-frame oil seal matches with the roll shaft external diameter being positioned at bearing support axis hole.
The utility model, in order to ensure the working life of special bearing, have employed novel sealing structure and protects it, double-deck skeleton-type oil seal is housed outside bearing to strengthen overall sealing effect; Outermost outside framework oil seal is arranged on bearing support inside, and endoporus contacts with the major axis through bearing hole and ensures to seal, and another outside framework oil seal endoporus and axle become inner ring external diameter surface to contact, and enhance bearing seal performance.
Skeleton-type oil seal, because oil sealing internal diameter size is less than axle journal, have certain magnitude of interference, oil sealing is contained in after on axle, and the pressure of its cutting edge and the contractile force of self-tightening spring produce certain radial enclasping force to seal shaft, and gap is revealed in blocking, reaches the object of sealing.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 bearing with spherical outside surface bottom surface, serves seal action to bearing.Ensure the inner oil sealing life-span.This class bearing is specially adapted to work under severe conditions, greatly can improve the working life of bearing.
Improve lubricating structure, lubricant oil arrives bearing with spherical outside surface side by oil nozzle, oil hole, directly can enter bearing working region, improve lubricating condition, improves bearing working life.
The utility model compact structure, good seal performance, improves the lubricating condition of bearing, improves the working life of bearing, decreases the workload of maintenance.
Accompanying drawing explanation
Do further statement below in conjunction with accompanying drawing to the utility model, Fig. 1 is main TV structure schematic diagram of the present utility model, and Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
Embodiment
A kind of film spreading machine pack roller sealed bearing structure, as shown in Figure 1 and Figure 2, with coordinating in the bearing hole of the circular shaft bearing 3 of adpting flange, bearing with spherical outside surface 4 is installed, coordinate in the concave station in the bearing block bearing hole on the right side of bearing with spherical outside surface 4 and inner frame oil sealing 2 and outer-frame oil seal 1 are installed, wherein the endoporus of inner frame oil sealing 2 matches with the inner ring external diameter of bearing with spherical outside surface 4, and the endoporus of outer-frame oil seal 1 matches with the roll shaft external diameter being positioned at bearing support axis hole.End face between the inner ring and outer ring of bearing with spherical outside surface 4 left end coordinates seal ring 5 is installed.Bearing support 3 arranges the oilhole being communicated with bearing with spherical outside surface 4 outer ring interior edge face oil pocket, oilhole is installed with Pressure oil nipple 6.
The utility model is particularly suitable for working under severe conditions.
