Description
Technical Field
The utility model relates to a mechanical transmission field, especially an overload protection shaft coupling.
Background
The coupling is a device for connecting two shafts or a shaft and a rotating part, rotating together in the process of transmitting motion and power and not separating under normal conditions. In the industry, the linear connection of the motor and the rotating shaft is completed by the coupler at present, and the common coupler has no overload protection, so that the requirements of motor locking, overload protection and limiting in the mechanical industry cannot be met.
Disclosure of Invention
An object of the utility model is to provide an overload protection shaft coupling. The utility model discloses can be in the transmission of load inner shaft, when the motor card is dead, need overload protection and spacing, can let the pivot stop, and the motor continues at the load internal rotation.
The utility model adopts the following technical scheme to realize the purpose of the invention:
the utility model provides an overload protection shaft coupling, includes drive spindle load pivot shaft coupling sleeve, and drive spindle load pivot shaft coupling sleeve is connected with the accurate internal rotation axle of shaft coupling, and the accurate internal rotation axle of shaft coupling is stretched into in the load pivot shaft coupling sleeve, is equipped with the spring mounting hole on the load pivot shaft coupling sleeve, is equipped with the spring in the spring mounting hole.
In the overload protection coupling, a driving spindle connecting hole is formed in the coupling sleeve of the driving spindle load rotating shaft, and two driving spindle locking screw holes are formed beside the driving spindle connecting hole.
In the overload protection coupling, the precise inner rotating shaft of the coupling is connected with the coupling sleeve of the load rotating shaft through a coupling screw.
In the overload protection coupling, a gasket is arranged between the coupling screw and the coupling sleeve of the load rotating shaft.
In the overload protection coupling, one end of the load rotating shaft coupling sleeve is provided with a coupling precision inner rotating shaft precision through hole, and the other end of the load rotating shaft coupling sleeve is provided with a load rotating shaft coupling hole; and a load rotating shaft locking screw hole is formed beside the load rotating shaft connecting hole.
In the overload protection coupling, the driving spindle load rotating shaft coupling sleeve and the coupling precision inner rotating shaft are integrally arranged.
In the overload protection coupling, the driving main shaft coupling sleeve and the load rotating shaft coupling sleeve can relatively slide and asynchronously rotate when the load is too large, and the load rotating shaft coupling sleeve does not have clamping stagnation on the driving main shaft coupling sleeve.
The utility model has the advantages that: compared with the prior art, the utility model discloses during the use, when external factor or requirement and to the motor card die, transship or when spacing, the load pivot is motionless, can not harm the motor yet. The friction force of the coupler is relatively fixed under the action of the spring. In designing, the frictional force is designed to be smaller than the driving force of the driving main shaft. Thus, when the load is smaller than the friction force of the spring, the driving main shaft coupling sleeve and the load rotating shaft coupling are synchronously rotated, and the load is a real load: when the load is greater than the friction force of the spring, the load rotating shaft coupling sleeve and the rotating shaft in the coupler precision device can slide relatively, the driving main shaft coupling sleeve and the load rotating shaft coupling sleeve rotate asynchronously, the load teaching rotating shaft is stuck, the driving main shaft rotates normally, the real load is equal to the friction force of the spring and is less than the load, and therefore the motor is protected.

Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention. The structures which are not particularly noted are all the prior art in the field.
Examples are given. An overload protection coupling is shown in figures 1-2 and comprises a driving spindle load rotating shaft coupling sleeve 1, wherein the driving spindle load rotating shaft coupling sleeve 1 is connected with a coupling precision inner rotating shaft 2, the coupling precision inner rotating shaft 2 extends into a load rotating shaft coupling sleeve 3, a spring mounting hole 4 is formed in the load rotating shaft coupling sleeve 3, and a spring 5 is arranged in the spring mounting hole 4.
And a driving main shaft connecting hole 6 is formed in the driving main shaft load rotating shaft coupling sleeve 1, and two driving main shaft locking screw holes 7 are formed beside the driving main shaft connecting hole 6.
The precise inner rotating shaft 2 of the coupler is connected with the load rotating shaft coupling sleeve 3 through a coupling screw 8.
A gasket 9 is arranged between the connecting screw 8 and the load rotating shaft coupling sleeve 3.
One end of the load rotating shaft coupling sleeve 3 is provided with a coupling precision inner rotating shaft precision through hole 10, and the other end is provided with a load rotating shaft connecting hole 11; and a load rotating shaft locking screw hole 12 is arranged beside the load rotating shaft connecting hole 11.
The driving main shaft load rotating shaft coupling sleeve 1 and the coupling precision inner rotating shaft 2 are arranged integrally.
The utility model discloses a use method and theory of operation: the utility model discloses during the use, fix the output shaft of motor in drive spindle connecting hole 6, fix the pivot in load pivot hookup hole 11. When the motor outputs power, the driving main shaft load rotating shaft coupling sleeve 1 is driven to rotate, the friction force generated by the pressure of the spring 5 in a compressed state drives the load rotating shaft coupling sleeve 3 to rotate, and the load rotating shaft coupling sleeve 3 drives the rotating shaft to rotate. When the motor is locked, overloaded or limited by external factors or requirements, the rotating shaft is not moved, and the friction force generated by the spring 5 at most by the outside is reacted to the motor, namely the external load is larger, and the real load of the motor is equal to the friction force generated by the spring 5 at most. Therefore, the motor continues to rotate because of no large real load, and the motor is protected.
