Abstract
The invention discloses a structurally improved drum gear coupling, which comprises an internally toothed annulus and a drum toothed sleeve. According to the use direction as the reference, the internally toothed annulus is hermetically sleeved on the circumferential outside of the drum toothed sleeve, the outer circumferential sidewall of the drum toothed sleeve is provided with drum teeth which are engaged with the inner side of the internally toothed annulus, and the drum toothed sleeve is axially extended out of the internally toothed annulus to form a connecting shaft. The structurally improved drum gear coupling can be connected with connected parts through tensioning disks, effectively overcomes the problems of a clearance and axial endplay in flat key coupling, also enhances the strength of a shaft sleeve, does not constrain the diameter of a coupling shaft, overcomes the circumstance that a small-specification coupling cannot be used due to large shaft diameter, is more convenient to mount, has a more compact structure and higher bearing capability, and is more economic and practical, the stability and safety of the operation of the coupling are sufficiently guaranteed, consequently, the production efficiency is increased, the maintenance time is shortened, and the maintenance cost is reduced.
Description
Technical field
The present invention 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 high-speed overloads 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, requirement improves constantly with stationarity to the transmitting torque ability of coupling; And installing space is restricted, and therefore when satisfying installation requirement, must improve structure, the bind mode of its core part as much as possible; 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, and 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.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of structure improved crown gear coupling, this structure improved crown gear coupling is simple in structure, motion is steady, transmitting torque is big, convenient disassembly, safe and reliable.
The present invention 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, be benchmark to use direction, said 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; Said crowned teeth cover stretches out the ring gear outer fix and extends axially the formation coupling shaft, and like this, the crowned teeth of crown gear coupling puts the axle that direct formation is connected with link; Can directly be fixedly connected through tension disk with link; The form that need not to connect through interference fit or key again is connected with link, and linkage structure is stable, convenient disassembly.
As further improvement of the present invention, the coupling shaft that said 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 invention is: crowned teeth of the present invention puts the coupling shaft that is provided with axial protrusion; It can connect through tension disk and link; Effectively overcome gap and axial float when flat key connects, strengthened the intensity of axle sleeve again and do not had the diameter constraint, overcome the situation that to select the small dimension coupling because of the diameter of axle greatly for use connecting the diameter of axle; Its installation is more convenient, more compact structure, higher, the more economical practicality of bearing capacity; Fully guarantee the stability and the safety type of coupling work, thereby improved manufacturing efficiency, reduced engineering time and maintenance expenses.

Embodiment
Embodiment: a kind of structure improved crown gear coupling, comprise ring gear 1 and crowned teeth cover 2, be benchmark to use direction; Said ring gear 1 stuffing box gland is located at crowned teeth and is overlapped 2 periphery, and crowned teeth is overlapped 2 periphery walls and is provided with the crowned teeth with ring gear 1 inner mesh, and said crowned teeth cover 2 stretches out ring gear 1 outer fix and extends axially and form coupling shaft 21; Like this; Directly form the axle that is connected with link on the crowned teeth cover 2 of crown gear coupling, can directly be fixedly connected with link through tension disk 3, the form that need not to connect through interference fit or key again is connected with link; Linkage structure is stable, convenient disassembly.
