Description

Step motor cover plate capable of smoothly rotating

Technical Field

The utility model relates to a step motor field especially relates to a step motor apron smooth and easy to rotate.

Background

Stepping motor is very extensive in purpose, like the fan field, this type of stepping motor has some drawbacks at present, and the axis of rotation passes the apron and drives, at this in-process and apron friction fit to produce certain noise, and influence pivoted smoothness nature, still can wear and tear so for a long time.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, the present technical solution provides a step motor cover plate that rotates smoothly.

In order to achieve the purpose, the technical scheme is as follows:

the utility model provides a rotate smooth and easy step motor apron, includes the apron body, the motor shaft of apron body passes the department and is equipped with a plurality of and passes through baffle divided cavity, the inboard extension of cavity has separation portion be equipped with spring and promotion portion in proper order in the cavity, the other end of promotion portion is equipped with the ball.

In some embodiments, the pushing portion is of U-shaped design and mates with the ball.

In some embodiments, the pushing portion has extensions extending from lower ends of both sides, and pulleys are disposed below the extensions.

In some embodiments, the inner wall surface of the pushing part is provided with a plurality of through holes, and the outer side of the pushing part is coated with sound absorption cotton.

In some embodiments, the cover plate body is provided with mounting portions on two sides and a positioning portion on one side.

The beneficial effect of this application does:

this application passes the department at the through-hole of apron and is provided with can pivoted gyro wheel, when the drive shaft rotates, can let the gyro wheel also rotate thereupon simultaneously to can not produce the noise, and can be more smooth and easy under the frictionless power.

Detailed Description

In order to make the technical problem, technical solution and advantageous effects solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to further explain the present invention in detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-5, a step motor cover plate capable of smoothly rotating includes a cover plate body 1, a plurality of chambers 3 partitioned by a partition plate 2 are disposed at a position where a motor rotating shaft of the cover plate body 1 passes through, a blocking portion 4 extends from an inner side of the chambers 3, a spring 5 and a pushing portion 6 are sequentially disposed in the chambers 3, and balls 7 are disposed at the other end of the pushing portion 6.

At first separate a plurality of cavity through the baffle, be provided with the ball in the cavity, the ball is spacing by baffle and separation portion to make the ball rotation in the confined area, and some extends the cavity, and after the seat of rotating passed, the axis body outer wall all contacted with the ball, so that when it was rotatory, drove the ball and rotate thereupon.

Further, the inner wall of cavity is provided with the spring, and the spring is connected with promotion portion, and the U-shaped opening and the ball butt of promotion portion can force the ball to the side movement of spring when error or threaded axis of rotation appear in the processing to the axis of rotation to make the spring compression, not only can guarantee ball and axis of rotation butt, can also avoid axis of rotation and ball rigid fit through the spring, produce the effort of a buffering, can also adapt not unidimensional axis of rotation.

In the present exemplary embodiment, the pushing element 6 is of U-shaped design and is matched to the ball 7.

In this embodiment, the lower ends of the pushing portions 6 on both sides extend to form extending portions 8, and pulleys 9 are disposed below the extending portions 8, so that when the balls move toward the spring side, the pulleys can have good sliding capability, the moving smoothness is improved, and noise is reduced.

In this embodiment, the inner wall surface of the pushing part 6 is provided with a plurality of through holes 10, the outer side of the pushing part 6 is coated with sound absorbing cotton 11, and noise generated in the cavity is transmitted to the sound absorbing cotton through the through holes to be absorbed, so that the noise is further reduced.

In this embodiment, the cover plate body 1 is provided with mounting portions 12 on both sides thereof and a positioning portion 13 on one side thereof.

The above description is only for the purpose of illustrating the preferred embodiments of the present application and is not intended to limit the scope of the present application, which is within the scope of the present application, except that the same or similar principles and basic structures as the present application may be used.
