Abstract
The utility model discloses a crowned teeth coupling with an improved structure, which comprises an inner tooth ring and a crowned toothed sleeve. Based on a use direction, the inner tooth ring is sleeved on the outer side of the circumference of the crowned toothed sleeve, crowned teeth which are meshed with the inner side of the inner tooth ring are arranged on the outer side wall of the circumference of the crowned toothed sleeve, and the crowned toothed sleeve extends out of the outer side position of the inner tooth ring and axially extends to form a connection shaft. In the utility model, through connecting a tension plate with a connector, gaps and axial displacement in flat key connection are effectively overcome, the intensity of a shaft sleeve is enhanced, the diameter of the connection shaft is not directly limited, and the disadvantage that a small-size coupling can not be used owing to a large shaft diameter is overcome. The coupling is more convenient to install, the structure of the coupling is more compact, the carrying capacity of the coupling is higher, the coupling is more economic and practical, the stability and the safety of coupling work are fully guaranteed, therefore, production efficiency is increased, and maintenance time and maintenance cost are reduced.
Description
Technical field
The utility model relates to a kind of coupling, particularly a kind of structure improved crown gear coupling.
Background technique
Crown gear coupling is to connect two coaxial line transmissions, allow two between centers have bigger axially, angle, radial displacement, and the important transmission basic part of transmitting movement and moment of torsion.Crown gear coupling is widely used in the transmission shaft part of heavy duty at a high speed such as rolling machinery, papermaking equipment, crane gear, wind-powered electricity generation transmission as transmitting motive basic part.In recent years, because the fast development of production technology, transmitting torque ability and stationarity to coupling require to improve constantly, and installing space is restricted, therefore when satisfying installation requirement, must improve the structure of its core part as much as possible, bind mode, to improve the structure stability and the bearing capacity of coupling, the crown gear coupling connection form all adopts axis hole to add flat key connection or Desing of Interference Joint mode at present, axis hole adds the intensity that the flat key bind mode has not only weakened the external tooth axle sleeve, and the keyway gap is difficult to control, in the middle of operation, can produce noise, Desing of Interference Joint mode shaft hole diameter not only is restricted, and magnitude of interference too conference cause deformation of tooth surface, give to manufacture and on-the-spot practical application brings inconvenience.
The model utility content
In order to remedy above deficiency, the utility model provides a kind of structure improved crown gear coupling, and this structure improved crown gear coupling is simple in structure, motion is steady, transmitting torque is big, convenient disassembly, safe and reliable.
The utility model for the technological scheme that solves its technical problem and adopt is: a kind of structure improved crown gear coupling, comprise ring gear and crowned teeth cover, to use direction to be benchmark, described ring gear stuffing box gland is located at crowned teeth cover periphery, crowned teeth cover periphery wall is provided with the crowned teeth with the ring gear inner mesh, described crowned teeth cover stretches out the ring gear outer fix and extends axially the formation coupling shaft, like this, the crowned teeth of crown gear coupling puts the axle that direct formation is connected with link, can directly fixedly connected by tension disk with link, the form that need not to connect by interference fit or key again is connected with link, linkage structure is stable, convenient disassembly.
As further improvement of the utility model, the coupling shaft that described crowned teeth puts is the multidiameter shaft that contracts in the diameter, and this structure is convenient to be connected and the location, connects and stablizes, and transmitting torque is big.
Useful technique effect of the present utility model is: crowned teeth of the present utility model puts the coupling shaft that is provided with axial protrusion, it can connect by tension disk and link, gap and axial float when flat key connects have effectively been overcome, strengthened the intensity of axle sleeve again, and there is not the diameter constraint to connecting the diameter of axle, overcome the situation that to select the small dimension coupling because of the diameter of axle greatly for use, its installation is more convenient, more compact structure, bearing capacity is higher, more economical practicality, the stability and the safety type of coupling work have fully been guaranteed, thereby improved manufacturing efficiency, reduced engineering time and maintenance expenses.
