Conical shaft coupler

Abstract

The utility discloses a conical shaft coupler. The conical shaft coupler comprises a connection pipe and shaft heads located at the two ends of the connection pipe; the two ends of the connection pipeare provided with shaft sleeves used for installing the shaft heads and provided with inner cone holes; positioning sleeves used for being installed between the shaft sleeves and the shaft heads arefurther included; the connection ends of the shaft heads are arranged into frustum structures with the diameter gradually increased from the root portion of the shaft heads to the outward portions; each positioning sleeve is composed of two structures opened in opposite directions; each positioning sleeve is provided with an inner hole matched with the outer surface of the frustum of the corresponding shaft head, and an outer conical face matched with the inner cone hole of the corresponding shaft sleeve; and the connection ends of the shaft heads are installed on the shaft sleeves after beingsleeved with the positioning sleeves. After the above structure is adopted, installing is convenient, after installing, the connection ends of the shaft heads are made to be limited in the positioning sleeves, the problem that the shaft heads disengage from the connection pipe is completely and effectively prevented, locking becomes more reliable along with disengaging, and the self-locking effect is achieved.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to a tapered shaft coupling. Background technique [0002] A shaft coupling is a device used to connect components to achieve torque transmission. The existing couplings generally include connecting pipes and joints installed at both ends of the connecting pipe. The joints are fixed and installed through the connecting sleeve and the connecting pipe. Some structures are commonly used and widely used, but due to their simple structural design, although they can achieve reliable transmission of power, they are generally installed by hitting with a hammer during installation, which is troublesome to install, and it is more difficult to disassemble when they need to be replaced after installation. For inconvenience, in addition, after the connection, the problem that the shaft head and the connecting pipe are often disengaged makes the use reliability poor.
