(1), the utility model structure is simple, easy to process, and assembling is with easy to maintenance.
(2), the utility model is simple, convenient, quick, improves manufacturing efficiency.
(3), the utility model has overload protection function, can available protecting driving device and load, avoids producing and destroys.
(4) the utility model is separated rapid, safety, applied widely; And can also reset easily after isolation, can reuse, save material and user cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure: the coupling with overload protection in embodiment is primarily of compositions such as adjustable collar 2, spring 3, axle sleeve 4, drive pin 5 and follower pin 6.
As shown in Figure 1, described adjustable collar 2 is arranged on input shaft 1, and described spring 3 is enclosed within input shaft 1, and spring 3 rear end connects adjustable collar 2, spring 3 front end connecting bushing 4; Described axle sleeve 4 second half section is enclosed within input shaft 1 end and offsets with spring 3, and axle sleeve 4 second half section is provided with a L shape cotter way 4a, and L shape cotter way 4a comprises the axial groove and transverse groove that are connected; Be provided with a drive pin 5 in described L shape cotter way 4a, this drive pin 5 is connected on input shaft 1; Described axle sleeve 4 first half section is enclosed within output shaft 7 end, and axle sleeve 4 front end is provided with a V-notch 4b, and the degree of depth of this V-notch 4b is less than the degree of depth of axial groove in L shape cotter way 4a; Described output shaft 7 is installed with a follower pin 6, described follower pin 6 contacts with each other with axle sleeve 4 front end and coordinates, when follower pin 6 correspondence to embed in described V-notch 4b and when being withstood by spring 3, output shaft 7 and input shaft 1 form an entirety, transmitting torque and power can be used for.
As shown in Figure 1, in the utility model embodiment, described adjustable collar 2 is threaded connection and is arranged on input shaft 1, and adjustable collar 2 can move axially the elastic force that fine setting adjusts spring 3, thus can preset load rating force value.And described adjustable collar 2 is provided with scale.What accurately can control adjustable collar 2 like this moves axially distance, improves control accuracy.
During installation, first adjustable collar 2 and spring 3 are contained on input shaft 1 in turn, then axle sleeve 4 are contained on input shaft 1, then drive pin 5 is contained in the fixed pin holes of input shaft 1 through L shape cotter way 4a; Again axle sleeve 4 is enclosed within output shaft 7, output shaft 7 inserts follower pin 6, rotate and regulate axle sleeve 4, follower pin 6 correspondence is made to embed in the V-notch 4b of axle sleeve 4 front end, under spring 3 acts on, output shaft 7 just forms an entirety with input shaft 1, can be used for transmitting torque and power.
Working principle of the present utility model is as follows:
When there is overload fault (moment of torsion exceedes setting value), follower pin 6 can skid off from the V-notch 4b of axle sleeve 4 front end and promote the active force that axle sleeve 4 overcomes spring 3 and move right, and spring 3 is compressed; Due to the existence of torque on axle, axle sleeve 4 also can rotate while movement, and such drive pin 5 will enter in transverse groove from the axial groove of L shape cotter way 4a, and at this moment follower pin 6 and the contact position of axle sleeve 44 change, and follower pin 6 leaves v-notch; The degree of depth of V-notch 4b is less than the degree of depth of axial groove; the axial displacement that such L shape cotter way 4a place drive pin 5 produces when being entered transverse groove by axial groove can be greater than the relative displacement between follower pin 6 and axle sleeve 4; follower pin 6 to be thrown off with axle sleeve 4 and contacted; input shaft 1 and output shaft 7 can throw off connection, so just play the effect of overload protection.
Regulate axle sleeve 4 that follower pin 6 can also be made again to embed v-notch by rotating, spring 3 is resetted, coupling can be in again can the state of transmitting torque and power.
