Abstract
The utility model relates to a single engagement type coupling, which belongs to the technical field of an engaging tooth type coupling. The single engagement type coupling is used for solving the defect of poor operational reliability of the coupling in the adverse industrial-mineral environment, and is composed of a shaft sleeve with a flange, shaft sleeves with an outer gear and an inner tooth ring with a flange, wherein the two shaft sleeves are used for being connected with two butted shafts, and the inner teeth arranged on the inner gear is engaged with the outer teeth arranged on the shaft sleeve; the flange arranged on the inner tooth ring is connected with the flange arranged on the shaft sleeve through a screw bolt. After improved, the inner and the outer teeth are rectangular teeth, and the rectangular inner teeth are arranged on the flange of the inner tooth ring. The rectangular outer teeth are arranged on one end of the shaft sleeve. The number of the rectangular inner teeth and the rectangular outer teeth is three to six. The utility model has the obvious advantages of small sliding friction, low requirement of lubricated condition, convenient observation for adding lubricant grease, large tooth shape, high carrying capacity, reliable operation, long service life, etc. and is suitable for being used in the adverse environment of operating conditions, such as the metallurgy, the mining area, the electric power, etc., particularly in the conveying roller way of an outlet of a heating furnace of a steel rolling production line.
Description
Technical field
The utility model relates to the engagement gear coupling in the packaged type rigid coupling, and especially single engagement type coupling belongs to engagement gear coupling technical field.
Background technique
The engagement gear coupling is most widely used a kind of in the packaged type rigid coupling, has the bearing capacity height, and reliable operation compensates advantages such as the diaxon relative displacement is good, and shortcoming is to make difficulty, needs good lubricating in the work.The branch that single engagement type (CLZ type) and two engagement type (CL type) arranged on the structural type.Single engagement type axle sleeve and flanged (FLGD) ring gear by flanged (FLGD) axle sleeve, band external gear formed, the diaxon cover is used for linking with two abutment shafts, internal tooth on the ring gear is meshed with external tooth on the band external gear axle sleeve, and the flange on flange on the ring gear and the flanged axle sleeve passes through Bolt Connection.Inside and outside tooth is an involute tooth, and contact points is positioned at the intermediate portion of ring gear.The engagement type coupling of this kind list, the contact points position is hidden, is inconvenient to pour into a mould lubricant grease, is difficult for keeping good lubricating; Simultaneously, be subjected to the restriction of ring gear radial structure size, the modulus of involute tooth is unsuitable excessive, and the number of teeth generally is no less than 30, and little, the single tooth bearing capacity of profile of tooth is lower, and when poor lubrication, the fast easy-rupturing of tooth surface abrasion is difficult to adapt to bad working environment.When being used for high temperature with high dust and adding the metallurgical steel rolling production-line that cooling water splashes, functional reliability and working life greatly reduce, and therefore make the maintenance load multiplication., must improve for this reason, make it overcome above-mentioned disadvantage the engagement type coupling of existing list.
Summary of the invention
Technical problem to be solved in the utility model is to improve the functional reliability of single engagement type coupling under abominable industrial and mineral environment, thereby makes the usage requirement of industries such as its satisfied metallurgy.
The alleged problem of the utility model realizes with following technological scheme:
The engagement type coupling of a kind of list, axle sleeve 2 and flanged (FLGD) ring gear 3 by flanged (FLGD) axle sleeve 1, band external gear are formed, axle sleeve 1,2 is used for being connected with two abutment shafts, internal tooth on the ring gear is meshed with external tooth on the axle sleeve 2, and the flange on the ring gear connects by bolt 4 with flange on the axle sleeve 1, and its improvement is, described inside and outside tooth is a rectangular teeth, rectangle internal tooth 5 is arranged on the flange of ring gear 3, and rectangle external tooth 6 is arranged on axle sleeve 2 one ends, and the number of teeth of the inside and outside tooth of rectangle is 3～6.
The engagement type coupling of above-mentioned list, the inside and outside tooth of described rectangle is 4.
Inside and outside tooth in the utility model adopt rectangular teeth and little number of teeth structure and be arranged on the ring gear flange and axle sleeve one end after have following characteristics:
1. the sliding friction when having reduced the engagement of the inside and outside tooth of former little modulus involute, when having reduced work to the requirement of lubricating condition;
2. contact points moves to the end flange place by hidden ring gear inside, outside contact points is exposed to, has made things convenient for the interpolation of lubricant grease and the observation of lubrication circumstances;
3. after contact points moves to the end flange place,, the little number of teeth, the design of heavy in section rectangular teeth can be adopted, the bearing capacity of inside and outside tooth can be improved owing to have bigger radial space;
4. the existing relatively involute tooth of rectangular teeth is easier to processing, and fabricating cost is low;
The utlity model has remarkable advantages such as lubricating requirement is low, bearing capacity is high, use Q-percentile life is long, solved the problem that the engagement type coupling of existing list is difficult to reliable operation in the high temperature with high dust rugged environment, suited in abominable industrial and mineral environment such as metallurgy, mine, electric power, especially use in the steel rolling production-line furnace outlet rollgang.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A sectional drawing of Fig. 1.
The component label is in the accompanying drawing: the flanged (FLGD) ring gear of axle sleeve, 3-, the 4-bolt of the flanged (FLGD) axle sleeve of 1-, 2-band external gear, 5-rectangle internal tooth, 6-rectangle external tooth.
Embodiment
In the illustrated embodiment, the number of teeth of the inside and outside tooth of rectangle is 4,4 rectangle external tooths 6 on the axle sleeve 2 are the cross convex, four rectangle internal tooths 5 on the ring gear flange are the cross recess shape, the facewidth of rectangle internal tooth 5 is a bit larger tham the facewidth of rectangle external tooth 6, can make the corresponding reduction of machining accuracy conveniently to be combined.
