Abstract
The utility model belongs to the technical field of motors, and particularly relates to a structure of a shaft of a variable frequency motor with an encoder. The shaft of the variable frequency motor with the encoder comprises a large shaft and a small pillow block, wherein a central hole is formed at one end of the outer covering table of the large shaft; a connecting piece is connected to the small pillow block at the end connected with the large shaft, and comprises a screwed end, a tightening platform, and a conical surface body between the screwed end and the tightening platform; the small pillow block is connected with the tightening platform; and the small pillow block is connected the large shaft through the method that the screwed end of the connecting piece is inserted into and in threaded connection with the central hole. As the large shaft and the small pillow block are two integral bodies, when the small pillow block breaks down during a processing or transportation process, all that is needed is to replace the small pillow block with the connecting piece, so as to avoid the phenomenon that the whole large shaft is scrapped at the same time. Therefore, economical treatment is guaranteed during failure, which saves cost.
Description
Technical field
The utility model belongs to technical field of motors, is specifically related to a kind of structure of axle of the variable-frequency motor with encoder.
Background technique
Variable-frequency motor adopts the AC speed-regulating mode of " special-purpose variable frequency induction motor+frequency variator ", and mechanical automation degree and manufacturing efficiency are greatly improved, and makes device miniaturization, increases travelling comfort, is just replacing traditional mechanical speed governors and DC speed regulation scheme at present.Variable-frequency motor is in order to realize the control to motor speed; Encoder need be installed on variable-frequency motor; The motor macro-axis is the enclosing cover platform near an end of fan; Generally be the little pillow block of directly processing a φ about 6 in the enclosing cover platform back of macro-axis, then little pillow block couples together through a coupling and encoder again.But for the bigger motor of capacity, the enclosing cover platform diameter of its motor macro-axis generally all more than 100, is processed the little pillow block of φ about 6 at φ above that, and difficulty is bigger; If go wrong in processing or the medium and small pillow block of transportation process, the macro-axis of so whole motor and little pillow block will be scrapped, and are unfavorable for very much organization of production.
The model utility content
The purpose of the utility model provides a kind of axle of variable-frequency motor of band encoder of replaceable little pillow block.
The utility model adopts following technological scheme:
The axle of the variable-frequency motor of band encoder; Comprise macro-axis and little pillow block; End at the enclosing cover platform of macro-axis is provided with a center hole, and an end that is connected with macro-axis on the little pillow block is provided with link, link by threaded end, tighten platform and threaded end and the conical surface body tightened between the platform constitutes; Little pillow block with tighten platform and be connected, link inserts in center hole through its threaded end and through being threaded little pillow block and macro-axis is coupled together.
The upper and lower surfaces of tightening platform is the plane, is convenient to the operation of tightening tool.
Said center hole is a C type center hole.
The diameter of the center hole of macro-axis is M24, and the degree of depth is 50, and the diameter of link threaded end is M24.
The utility model is split up into two-part with the macro-axis and the little pillow block of original one processing; End face at the enclosing cover platform of macro-axis is provided with center hole; End that is connected with macro-axis at little pillow block is provided with link, and the threaded end of link couples together through being coated with tight glue of screw thread and center hole, prevents to become flexible; Conical surface body in the middle of the link guarantees the requirement of concentricity between macro-axis and little pillow block fixing back macro-axis and the little pillow block, and the upper and lower surfaces of tightening platform is the plane, is convenient to the operation of tightening tool.The utility model is adding man-hour; Macro-axis is as a whole, and the processing of little pillow block and link is as a whole, and the utility model is being processed or the medium and small pillow block of transportation process when going wrong like this; Only changing a little pillow block that has link gets final product; The situation of having avoided whole macro-axis to scrap simultaneously also can have economic mode to handle even guaranteed to go wrong, and has practiced thrift cost.

Fig. 1 is the macro-axis structural representation of the utility model;
Fig. 2 is the little pillow block structural representation of the utility model;
Fig. 3 is the right elevation of Fig. 2;
Fig. 4 is the assembling schematic representation of the utility model macro-axis and little pillow block.
Embodiment
Axle like the variable-frequency motor of Fig. 1,2,3, the band encoder shown in 4; Comprise macro-axis 1 and little pillow block 7, at an end of the enclosing cover platform 3 of macro-axis 1 C type center hole 2 is set, an end that is connected with macro-axis 1 on the little pillow block 7 is provided with link 5; Link 5 by threaded end 4, tighten platform 6 and threaded end 4 and the conical surface body 8 tightened between the platform 6 constitutes; Conical surface body 8 guarantees the requirement of concentricity between macro-axis and little pillow block fixing back macro-axis 1 and the little pillow block 7, and the upper and lower surfaces of tightening platform 6 is the plane, is convenient to the operation of tightening tool; Little pillow block 7 with tighten platform 6 and be connected; Link 5 inserts in the C type center hole 2 through its threaded end 4 and through being threaded little pillow block 7 is coupled together with macro-axis 1, and threaded end 4 can be coated with the tight glue of screw thread when inserting in the C type center hole 2, prevents to become flexible.Then little pillow block 7 couples together with encoder and gets final product.
If the utility model is at processing or the medium and small pillow block 7 of transportation process when going wrong like this; Only needing to change a little pillow block 7 that has link 5 gets final product; The situation of having avoided whole macro-axis 1 to scrap simultaneously; Also can there be economic mode to solve processing even guaranteed to go wrong, have practiced thrift cost.
