Abstract
The utility model discloses a servo motor equipped with a shaft coupling. The servo motor comprises a shaft coupling through which a motor output shaft (5) is connected with an operating part input shaft (1). The shaft coupling is an elastic shaft coupling (2). A half of the elastic shaft coupling (2) is connected with the operating part input shaft (1), while the other half of the elastic shaft coupling (2) is connected with the motor output shaft (5). With such structure, a circular truncated cone protruding outwardly is disposed on a half of the elastic shaft coupling. In other words, a taper is provided. In addition, a taper hole matched with the circular truncated cone is disposed on the motor output shaft and the elastic shaft coupling and the motor output shaft are connected together through a bolt. Therefore, the length of the motor output shaft extended out of the housing of the motor is greatly shortened such that the rigidity of the motor output shaft is enhanced in order to prevent a fracture phenomenon.
Description
Technical field
The utility model relates to technical field of motors, is specifically a kind of servomotor with shaft coupling.
Background technology
Servomotor, has been widely applied to all trades and professions, and the output motor axle in servomotor is connected with parts such as oil pumps by shaft coupling conventionally.In shaft coupling of the prior art, normally motor output shaft is connected by spline fitted with power input shaft, therefore, motor output shaft will stretch in shaft coupling, like this, the length that motor output shaft stretches out casing is longer, the rigidity of the motor output shaft of this junction is just poor, easily occurs the phenomenon of motor output shaft fracture.
Utility model content
Technical problem to be solved in the utility model is, a kind of length that reduces motor output shaft is provided, thereby increases motor output shaft rigidity, avoids occurring the servomotor with shaft coupling of phenomenon of rupture.
For solving the problems of the technologies described above, the servomotor with shaft coupling that the utility model provides, comprises the shaft coupling that connects motor output shaft and workpiece power shaft; Described shaft coupling is spring coupling, and half in spring coupling is connected with workpiece power shaft, and second half is connected with motor output shaft.
The end of the described semi-flexible coupling being connected with motor output shaft has the round platform of past evagination, and the center of this semi-flexible coupling has axial stepped hole; On corresponding motor output shaft, there is the bellmouth matching with round platform, and bottom, the hole of bellmouth has the screwed hole extending internally; Between spring coupling and motor output shaft, be bolted.
Adopt after above structure, the utility model compared with prior art, have the following advantages: owing to being provided with the round platform toward evagination on half spring coupling therein, in other words, many one pushes away and pulls out, and on motor output shaft, be provided with the bellmouth matching with round platform, recycling bolt links together spring coupling and motor follower, therefore, can greatly shorten the length dimension that motor output shaft stretches out motor case, thereby increased the rigidity of motor output shaft, avoided occurring phenomenon of rupture.
Accompanying drawing explanation
Fig. 1 is the novel structural representation with the servomotor of shaft coupling of the utility model.
Wherein: 1, workpiece power shaft; 2, spring coupling; 3, bolt; 4, round platform; 5, motor output shaft; 6, stepped hole; 7, bellmouth; 8, screwed hole.
