Abstract
The utility model discloses a novel shaft coupling used for transmission. Two shaft coupling devices, two transmission devices, and a connecting device are organically combined to form the novel shaft coupling used for transmission. Two connecting shaft sleeves are tightly fixed on the outer ends of the two transmission devices by bolts. The two transmission devices are connected through a shaft. The novel shaft coupling used for transmission has the advantages of simple structure, simple structure, easy processing and fabrication, stable transmission, safe work, long service life, etc.; the novel shaft coupling used for transmission can realize large flexing quantity within short spacing. The allowable inclination angle of the novel shaft coupling used for transmission is about 10 DEG, and the allowable torque of the novel shaft coupling used for transmission can be enhanced more than 50%. The novel shaft coupling used for transmission can conveniently substitute gear shaft couplings with various forms and cross shaft type universal shaft couplings on the basis that the original connecting form and the original connecting dimension are not changed.

The purpose of this utility model can realize by following measure:
Coupling is by two connection axle sleeves, two cover transmission devices and axle are formed, two connection axle sleeves are by the outer end of bolton at two cover transmission devices, connect by axle between the two cover transmission devices, every cover transmission device all is by the internal axle sleeve that has two or more open-minded hole slots on the end face circumference with dividing equally, correspondingly on circumference, be provided with the external axle sleeve of two or more gudgeons with internal axle sleeve, roller, the shelves lid, rubber parts is formed, roller is contained in respectively on the gudgeon of external axle sleeve, the combination of roller and external axle sleeve is packed in internal axle sleeve and the open-minded hole slot thereof, the outside is closed with the shelves cap seal, the rubber parts sealing, bolton.
The purpose of this utility model can also realize by following measure:
Coupling is made up of two cover transmission devices, and two cover transmission devices connect by bolton, and the structure of every cover transmission device as mentioned above.
The purpose of this utility model can also realize by following measure:
Coupling correspondingly is provided with two or more gudgeons by an internal axle sleeve that has two or more grooves in circumference, with internal axle sleeve on circumference external axle sleeve, roller, shelves lid, rubber parts are formed, and other are constructed as mentioned above.
The purpose of this utility model can also realize by following measure:
Open-minded hole slot and groove are cuboid shape or cylindrical.
Roller both can pass through rolling bearing, also can be contained on the gudgeon by sliding bearing.
Roller can be a cylindrical body, also can be spheroid.
Transmission device connects with axle, both can be to be fixedly connected, and also can be the connection that is slidingly matched of lead key and splined shaft.
