Abstract
The utility model discloses a through type crowned teeth coupling, which comprises a driving end, a driven end and a castellated shaft. The castellated shaft perforates the whole driving end consisting of a crowned teeth shaft housing of the driving end and an inner toothed sleeve of the driving end which is meshed with the crowned teeth shaft housing of the driving end and the highly precious centering sphere supporting arranged between the crowned teeth shaft housing of the driving end and the inner toothed sleeve of the driving end. A centering supporting device is arranged on the castellated shaft close to the driven end. When in application, the inner toothed sleeve of the driving end can be assembled along the two opposite axial directions of the castellated shaft according to demand. Aiming at the deficiencies that the original crowned teeth coupling is with a fixed length, and the device takes up larger space, which is without convenient maintenance and dismounting, and is difficult to meet the demands of high speed and over loading, the utility model provides a crowned teeth coupling.
Description
Technical field
The utility model relates to a kind of crown gear coupling.
Background technique
Crown gear coupling is required main transmission auxiliary equipments such as high-speed rod, bar, heat, cold continuous rolling plate mill, uses also very extensive in forging and pressing, mine, lifting, transportation, oil, chemical industry and other heavy machineries.All kinds of crown gear couplings that existing NBS is announced and traditional crown gear coupling of various widespread usage, its drive end and driven end all are the two ends that are positioned at spline pair, the length of this crown gear coupling immobilizes, in application, strengthened the bulk of the equipment that uses this coupling, equipment takes up space bigger, repair demolition inconvenience, such as rolling at milling train in the rod operation process, because the variation of roll spacing and change the needs of rod, the driven end of shaft joint need move axially, its amount of movement maximum can reach more than the 700mm, and traditional shaft joint is difficult to dismounting because extending amount is little, and when coupling itself needs repairing, its drive end position is difficult to move, and also brings very big inconvenience to maintenance, and cost of equipment maintenance is improved greatly, reduced working efficiency, increased cost of production, in production line was produced, the loss that stops production was very big.And along with the development of technology, traditional crown gear coupling also is difficult to satisfy high speed, wire rod, bar and the sheet material steel rolling equipment of heavy duty and the needs of other machinery main transmissions.
Summary of the invention
The purpose of this utility model is to immobilize at the length that existing crown gear coupling exists, equipment takes up space bigger, repair demolition inconvenience, with the deficiency that is difficult to satisfy high speed, heavily loaded needs, providing a kind of can stretch significantly, in the use repair demolition convenient, reduce equipment occupation space, the bearing capacity height, the crown gear coupling that operates steadily.
The purpose of this utility model is achieved in that a kind of through crown gear coupling, comprise drive end, driven end and splined shaft, its drive end comprises the drive end internal tooth casing, drive end crowned teeth axle sleeve, between drive end internal tooth casing and drive end crowned teeth axle sleeve, be provided with the high precision fixed core spherical bearing, the drive end internal tooth casing is by crowned teeth and the engagement of drive end crowned teeth axle sleeve, drive end crowned teeth axle sleeve is connected by its internal spline and splined shaft, splined shaft runs through whole drive end, thereby splined shaft can be moved freely in drive end crowned teeth axle sleeve vertically.Driven end comprises driven end internal tooth casing, driven end crowned teeth axle sleeve, and the position near driven end on splined shaft is provided with the centering bearing device, and the driven end internal tooth casing is by crowned teeth and the engagement of driven end crowned teeth axle sleeve, and driven end crowned teeth axle sleeve and splined shaft are affixed.In the use, the drive end internal tooth casing links to each other with the driving shaft of transmission system, and the internal spline and the splined shaft of drive end crowned teeth axle sleeve are connected, motion and power pass to driven end internal tooth casing and driven end crowned teeth axle sleeve by splined shaft, driven end crowned teeth axle sleeve is connected with driven shaft, makes motion and transmission of power give driven shaft.As required can be in application with the drive end internal tooth casing along two axial opposite direction assemblings of splined shaft.
Because the splined shaft of coupling can move freely vertically, make the drive end of coupling and the distance of driven end to regulate, coupling can stretch significantly, is beneficial to parts and service equipments such as dismounting maintenance and quick replacing roll, reduce maintenance cost, reduced the loss that stops production.Owing to adopt high precision fixed core spherical bearing and driven end centering bearing device, be beneficial to and operate steadily, drive end and driven end distance reduces in addition, not only make coupling be applicable to high speed, wire rod, bar and the sheet material steel rolling equipment of heavy duty and the needs of other machinery main transmissions, and strengthened the accommodation at coupling axis inclination angle, after using it on the equipment such as vertical mill, not only can make the equipment driven system compact structure, and obviously reduce device height and take up room the saving place.Because the drive end internal tooth casing can make coupling can be suitable for multi-form matching requirements such as plain-barreled roll, vertical miller along two axial opposite direction assemblings of splined shaft.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done detailed description:
Fig. 1 is that drive end internal tooth casing of the present utility model is just assembling cut-away view.
Fig. 2 is the anti-cut-away view that assembles of drive end internal tooth casing of the present utility model.
Embodiment
