Abstract
The utility model discloses a kind of cold extruding to stretch heavily loaded elastic caster, comprise wheel core assembly and be sleeved on the wheel rim of wheel core assembly tread periphery, described core assembly of taking turns comprises wheel hub, pair of bearings, inner sleeve, described wheel hub is two lobe sectional constructions, its both sides central hole location is outwardly shape, and pair of bearings is placed in this centre hole respectively; Described inner sleeve two ends are each passed through the bearing of both sides and two lobe Combined hubs are coaxially arranged, and two lobe joint places of described wheel hub are fixed by rivet.Taking turns core assembly in the design adopts stress to concentrate principle to process, and improves the structural strength of castor entirety, makes it better bear pressure; Optimize the fixed form of bearing, both ensure that bearing orientation problem in use, and also avoid the risk that position of bearings enters foreign material, reduce the damage of bearing secondary processing riveted joint; This castor manufacturing procedure is simple, low processing cost; While raising in-use performance, ensure that batch manufacturing efficiency, meet the demand of high-end market.
Description
Technical field
The utility model relates to the component in haulage equipment, refers to that a kind of cold extruding stretches heavily loaded elastic caster particularly.
Background technology
At present, in use, the castor especially in handling process requires himself have elasticity and can carry constant weight to industrial castor, according to performance operating needs and feature, tradition large carrying castor due to manufacturing process aging, pattern is single, morely adopts welding type hub and needs main equipment processing structure, can not meet the requirement of structural strength, moreover external form is unsightly single, production efficiency is low, and productive costs is too high, do not adapt to the development of technical application, can not meet the demand of market economy.
Summary of the invention
The purpose of this utility model is exactly to overcome the defect that existing industrial load-bearing caster exists, and provides a kind of and can improve Castor structure intensity, good looking appearance, meets in-use performance requirement, ensures that producing the cold extruding carried out smoothly stretches heavily loaded elastic caster.
For achieving the above object, cold extruding designed by the utility model stretches heavily loaded elastic caster, comprise wheel core assembly and be sleeved on the wheel rim of wheel core assembly tread periphery, its special character is: described core assembly of taking turns comprises wheel hub, pair of bearings, inner sleeve, described wheel hub is two lobe sectional constructions, its both sides central hole location is outwardly shape, and described pair of bearings is placed in this centre hole respectively; Described inner sleeve two ends are each passed through the bearing of both sides and two lobe Combined hubs are coaxially arranged, and two lobe joint places of described wheel hub are fixed by rivet.
Preferably, described wheel hub is cold extruding drawing and forming, and described wheel rim is that die casting is shaping, and described inner sleeve is cold-heading molding, and described wheel rim is adhesively fixed by adhesives and wheel hub tread.Like this, Castor structure intensity can be improved, reduce manufacturing procedure, and suitable wheel rim color and profile can be selected according to purposes.
Preferably, the corresponding bearing inner ring place, both sides of described outer wall of inside race is provided with location flange collar.Like this, can be effectively limited in castor use procedure by the cooperation of location flange collar and hub centre hole salient, the moving position of bearing, prevents bearing from deviating from, and optimizes the fixed form of bearing, avoids entering foreign material in use.
The utility model has the advantage of: take turns core assembly in the design and adopt stress to concentrate principle to process, improve the structural strength of castor entirety, make it better bear pressure; Optimize the fixed form of bearing, both ensure that bearing orientation problem in use, and also avoid the risk that position of bearings enters foreign material, reduce the damage of bearing secondary processing riveted joint; This castor manufacturing procedure is simple, low processing cost; While raising in-use performance, ensure that batch manufacturing efficiency, meet the demand of high-end market.
Accompanying drawing explanation
Fig. 1 is that the utility model cold extruding stretches the structural representation of heavily loaded elastic caster.
Fig. 2 is the structure for amplifying schematic diagram of inner sleeve in Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Cold extruding shown in Fig. 1 ~ 2 stretches heavily loaded elastic caster, comprise wheel core assembly 2 and be sleeved on the wheel rim 1 of wheel core assembly 2 tread periphery, it is characterized in that: wheel core assembly 2 comprises wheel hub 21, pair of bearings 22, inner sleeve 23, wheel hub 21 is in two lobe sectional constructions, its both sides central hole location is outwardly shape, herein by cold extruding drawing and forming, adopts mechanics to concentrate principle to process, well can bear pressure, reach the performance requriements of heavily loaded castor; Pair of bearings 22 is placed in both sides centre hole respectively; Inner sleeve 23 two ends are each passed through the bearing 22 of both sides and two lobe Combined hubs 21 are coaxially arranged, and two lobe joint places of wheel hub 21 are riveted fixing by the rivet 24 at spoke place.Wheel hub 21 is cold extruding drawing and forming, and wheel rim 1 is that die casting is shaping, and inner sleeve 23 is cold-heading molding; Wheel rim 1 is adhesively fixed by adhesives and wheel hub 21 tread, can improve Castor structure intensity, reduces manufacturing procedure, and can select suitable wheel rim 1 color and profile according to purposes; The corresponding two side bearing 22 inner ring places of inner sleeve 23 outer wall are provided with location flange collar 25, can be effectively limited in castor use procedure by the cooperation of location flange collar 25 and wheel hub 21 centre hole salient, the moving position of bearing 22, prevent bearing 22 from deviating from, optimize the fixed form of bearing 22, avoid entering foreign material in use.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all should think and belong to protection domain of the present utility model.
