Abstract
A connection device for a shaft comprises a sleeve, wherein the head portion of the sleeve is used for connecting a locking portion of a driving shaft, and the tail portion of the sleeve is used for connecting a shaft hole portion of a driven shaft. A transverse opening parallel to the axis of the sleeve and a longitudinal opening perpendicular to the axis of the sleeve are arranged on the locking portion, the middle of the longitudinal opening is communicated with the transverse opening, two ends of the longitudinal opening extend along the lateral wall of the locking portion, and the cross section of the longitudinal opening is larger than a sector surface of a half circumference. Threaded holes located on the same axis are arranged on the two lateral walls of the transverse opening, and locking screws connected with the two lateral walls of the transverse opening are installed in the threaded holes. By means of the structure, the connection device for the shaft is of an integral structure which is simple and compact. Besides, the locking screws are utilized to be matched with the opening of the locking portion so that the driving shaft and the driven shaft are connected firmly and reliably, no swinging happens, and accurate transmission of the power of a motor is guaranteed.
Description
Technical field
The utility model relates to a kind of connection set, relates in particular to a kind of axle that is used to connect two coaxial bobbins and uses connection set.
Background technique
Between the input shaft (being driven shaft) of the output shaft (being driving shaft) of motor and driving mechanism, generally be connected through coupling; And existing coupling mainly comprises respectively two half-couplings that are connected with driven shaft with driving shaft; Connect through screw again between these two half-couplings; Its structure more complicated, installation neither be very convenient; Simultaneously, the joint between two half-couplings is loosening easily, makes and rocks relatively between driving shaft and the driven shaft, influences the transmission of motor power.
Summary of the invention
Have above-mentioned deficiency in the existing technology in order to overcome, the utility model provide a kind of simple and compact for structure, easy for installation and fixation reliably axle use connection set.
The technological scheme that the utility model solves its technical problem is: use connection set for a kind of; Comprise a sleeve; The head of said sleeve is the tight lock part that is used to connect driving shaft; The afterbody of said sleeve is the axle hole that is used to connect driven shaft, and said tight lock part is provided with the transverse opening that parallels with the axis of said sleeve and one and the perpendicular longitudinal opening of axis of said sleeve, and the middle part of this longitudinal opening is connected with said transverse opening; Extend along the sidewall of said tight lock part at the two ends of this longitudinal opening; And the cross section of this longitudinal opening is the sector greater than 1/2nd circumference, offers the tapped hole that is positioned on the same axis on the two side of said transverse opening, and the lock screw of the two side that connects said transverse opening is housed in this tapped hole.
Further, be provided with counterbore with the nut touching position of said lock screw on the said tapped hole.
Further, the outer wall of said tight lock part is provided with and is used for the bearings mounted spacing shaft shoulder.
The utility model is packed driven shaft in the axle hole of sleeve into earlier, and driven shaft and axle hole is coupled together when mounted; Then driving shaft is packed in the tight lock part of sleeve; Load onto lock screw in the tapped hole on tight lock part, tighten lock screw then, be positioned at the transverse opening side walls and produce distortion; Transverse opening diminishes; Thereby make the internal diameter of tight lock part tighten to clamp the driving shaft that is positioned at tight lock part, thereby with being fixedly connected of driving shaft and tight lock part, being connected between realization driving shaft and the driven shaft.
In order to make the use that lock screw is installed does not influence the utility model afterwards, the nut touching position with lock screw on tapped hole is provided with counterbore, not only can hide the nut of lock screw, makes that also the utility model structure is simpler, uses convenient.Fixing for the ease of the utility model is provided with on the outer wall of tight lock part and is used for the bearings mounted spacing shaft shoulder, and outside the Bearing Installation tight lock part, and the inner ring of bearing is limited on the spacing shaft shoulder.
The beneficial effect of the utility model is: adopt said structure, the utility model is integral structure, and is simple and compact for structure; Simultaneously, adopt lock screw and opening on the tight lock part to cooperate, make firm and reliable connection between driving shaft and the driven shaft, can not rock the accurate transmission of assurance motor power.
Description of drawings
Fig. 1 is the structural representation of the utility model.
