Abstract
The utility model discloses a spherical drum-shaped gear coupler. The spherical drum-shaped gear coupler comprises a spherical outer gear sleeve and a flange inner gear sleeve, wherein the outer circle of the spherical outer gear sleeve is a drum-shaped gear, and the spherical outer gear sleeve is arranged in the flange inner gear sleeve through the drum-shaped gear. An inner bearing ring and an outer bearing ring are arranged on the spherical surfaces of the two ends of the spherical outer gear sleeve respectively, and the outer bearing ring, the inner bearing ring and the contact surface of the outer bearing ring and the spherical outer gear sleeve are spherical surfaces. The inner bearing ring and the outer bearing ring are fixedly arranged at the two ends of the flange inner gear sleeve through an inner pressing cover and an outer pressing cover respectively. An adjusting shim is arranged between the outer pressing cover and the end surface of the flange inner gear sleeve, and an oil injection hole is formed in the end surface of the outer pressing cover. The spherical drum-shaped gear coupler can bear large radial loads and transmit large torque, and is convenient to install and easy to maintain.
Description
Technical field
The utility model relates to a kind of coupling, more particularly relates to a kind of sphere drum-shaped tooth type shaft coupling, belongs to the transmission device technical field.
Background technique
Drum-shaped tooth type shaft coupling is a kind of novel flexible coupling, be mainly used in the reducer output shaft of lifting mechanism in crane gear and connecting of cable drum, also be applicable to other similarly not only transmitting torque but also machinery of bearing radial load, but can not be as the transmission that need bear thrust load.And general gear coupling centering precision in the running is not high, offset can aggravate the wearing and tearing of the flank of tooth, directly affects the working life of coupling.
Summary of the invention
The purpose of this utility model is to provide a kind of sphere drum-shaped tooth type shaft coupling, can prevent bias and the coupling of the flank of tooth that weares and teares.
The utility model is achieved by the following technical programs:
A kind of sphere drum-shaped tooth type shaft coupling, comprise sphere external tooth cover, flange internal tooth casing that cylindrical is crowned teeth, the sphere external tooth cover is arranged in the flange internal tooth casing by its crowned teeth, also be respectively equipped with interior load-carrying ring, outer load-carrying ring on the two ends sphere of sphere external tooth cover, the surface of contact of interior load-carrying ring, outer load-carrying ring and sphere external tooth cover is sphere, interior load-carrying ring, outer load-carrying ring are fixedly installed on respectively the two ends of flange internal tooth casing by internal gland, outer press cover, the end face of outer press cover also is provided with an oil hole.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid a kind of sphere drum-shaped tooth type shaft coupling, the end face of sphere external tooth cover also is provided with teeth directional location wearing and tearing pointer.
Aforesaid a kind of sphere drum-shaped tooth type shaft coupling, the gap between internal gland, outer press cover and sphere external tooth cover is provided with seal ring.
Aforesaid a kind of sphere drum-shaped tooth type shaft coupling, be provided with the adjustment pad between the end face of outer press cover and flange internal tooth casing.
The utility model, by the interior load-carrying ring that is arranged on sphere external tooth cover two ends, outer load-carrying ring, can effectively prevent sphere external tooth cover generation eccentric phenomena, can effectively protect the tooth of sphere external tooth cover; After not producing eccentric phenomena, can improve the stress equalization ability of coupling, can bear very large radial load and transmit larger torque, working stability is reliable; The sphere external tooth cover also is provided with teeth directional location wearing and tearing pointer, as early warning, safe and reliable; After eccentric or wearing and tearing occur the sphere external tooth cover, can, by adjusting the pad adjusting play, guarantee the normal operation of coupling; The utility model installation, easy to adjust, safeguard simple.
Advantage and disadvantage of the present utility model, will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiments, only provide as an example with reference to accompanying drawing.
