Abstract
The utility model relates to a gear ring type hoist, which is used for overcoming technical shortcomings caused by the great weight, weak strength and low hardness of gears in the conventional hoist. Large gears connected with a winding drum flange on the conventional hoist are replaced by gear rings, and the gear rings are manufactured by adopting a forging process, and are connected with the winding drum flange through hinging bolts, so that the hoist is lightened, the service life of the gear is prolonged, the performance of the hoist is improved, and the hoist is high in appearance quality.
Description
Technical field
The utility model relates to a kind of gear ring type headstock gear.
Background technology
Former headstock gear reel, big gear wheel are cast steel, Yi Bian pass through bolted connection with the reel flange; And inner ring gear is being connected through key with rotating shaft; Gear is fixed through dual connection like this, though this can fixation stability, this has increased the overall weight of headstock gear undoubtedly; Make machine become heavy more, increase the burden of rotating shaft.
Big gear wheel adopts cast steel, be prone to exist shrinkage cavity, crackle, burning into sand etc. to influence the defective of intensity, and the defective position is changeable; Do not find during, finish turning rough turn through being everlasting; Just reveal up to tooth Profile Machining is intact, defective seriously influences the strength of gear teeth, must scrap; Again the casting processing that feeds intake has increased the process-cycle of big gear wheel, has incured loss through delay the delivery duration of headstock gear.
The utility model content
The technical matters that the utility model will solve is: overcome the deficiency of prior art, a kind of gear ring type headstock gear is provided, solve the technological deficiency that traditional headstock gear middle gear is heavy, intensity is low.
The utility model solves the technical scheme that its technical matters adopted: a kind of gear ring type headstock gear; Comprise reel, gusset and be arranged on the rotating shaft at reel two-port place; Connect fixing between described rotating shaft and the reel inwall through gusset; Be fixed with the reel flange on the described reel port outer wall, be fixedly connected with gear ring on the described reel flange.
Furtherly, described gear ring adopts forging method to process.Forging quality improves a lot than steel casting, forge the back like defectiveness, then after forging, can find during ultrasonic flaw detection, does not just check after can not arriving gear and all processing; Forging can bear big impact force action, and plasticity, toughness and otherwise mechanical property are also all high than steel casting.
Furtherly, be connected through articulation bolt between described reel flange and the gear ring fixing.Plain bolt can bear horizontal and axial load; But the horizontal load method of bearing mainly is the friction force that brings by pre-fastening moment; And the articulation hole bolt also is can bear laterally and axial load; The method of bearing of transverse load is to lean on the shear strength of bolt itself, and its lateral bearing ability is far above plain bolt.
The beneficial effect of the utility model is: the utility model provides a kind of gear ring type headstock gear, changes the big gear wheel that is connected with the reel flange in the headstock gear in the past into gear ring, has effectively alleviated the weight of gear; As cast defective before gear ring is changed in addition; The existing method of forging that adopts is processed; Gear ring after the forging can be born higher impact force; Plasticity, toughness and otherwise mechanical property are also all high than steel casting, forging gear ring processing back than the cast steel gear production process lack, simple in structure, presentation quality good.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Wherein: 1, reel, 2, gusset, 3, rotating shaft, 11, the reel flange, 12, gear ring, 13, articulation bolt.
The specific embodiment
Combine accompanying drawing that the utility model is further described now.The scheme drawing that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of gear ring type headstock gear as shown in Figure 1; Comprise reel 1, gusset 2 and be arranged on the rotating shaft 3 at reel 1 two-port place; Connect fixing through gusset 2 between rotating shaft 3 and reel 1 inwall; Be fixed with reel flange 11 on reel 1 port outer wall, reel flange 11 is connected with gear ring 12 through articulation bolt 13, and gear ring 12 adopts forging method to process.
What be connected with reel flange 11 in the headstock gear is big gear wheel in the past, and big gear wheel also is connected with rotating shaft 3, makes headstock gear integral body too heavy like this; Structure is too complicated, changes big gear wheel into gear ring 12 now, and gear ring 12 fixes with reel flange 11 through 13 of articulation bolts; Reduced a part of quality; And gear ring 12 processes through the method for forging, and as cast defective before changing through forging can bear higher impact force the gear ring 12 after the forging; Plasticity, toughness and otherwise mechanical property are also all high than steel casting, forging gear ring 12 processing backs than the cast steel gear production process lack, simple in structure, presentation quality good.
Captive joint through articulation bolt 13 between gear ring 12 and the reel flange 11; Articulation bolt 13 all has merits and demerits separately with plain bolt; Plain bolt can bear horizontal and axial load, but the horizontal load method of bearing mainly is the friction force that brings by pre-fastening moment, and articulation bolt 13 also is can bear laterally and axial load; The method of bearing of transverse load is to lean on the shear strength of bolt itself; Its lateral bearing ability can find that according to the utility model articulation bolt 13 needs bear more transverse force far above plain bolt, so select for use articulation bolt 13 effectively to prolong the time of headstock gear safe operation.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification sheets, must confirm its technical scope according to the claim scope.
