The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1 to Figure 3, it is the cross section structure scheme drawing of the utility model embodiment, the utility model embodiment provides a kind of slip gear 10, comprise one 1, and be socketed on the belt wheel 2 of axle on 1, and and at least one roller 3 of these belt wheel 2 adjacency and at least one transmitting device 4 of driving pulley 2 rotations, the side closed contact that one side of this roller 3 and belt wheel 2 are relative, and an end of belt wheel 2 is provided with one first end face 21, roller 3 is provided with second end face 34 with these first end face, 22 closed contacts, promptly form friction face 8, thereby belt wheel 2 and roller 3 produce end-face friction on the friction face 8 that forms between first end face 22 and second end face 34.
On the bearing of trend of axle 1, described roller 3 inside are provided with the gap 35 of a hollow, be provided with springing 5 in this gap 35, originally be among the embodiment, this springing 5 is a spring, certainly also can be other rubber-like parts, that is: this slip gear 10 is connected on the roller 3 at the bearing of trend of axle 1, and force roller 3 to the close springing 5 of belt wheel 2, this springing 5 can be one, also can be a plurality of, as long as can realize that roller 3 is close to belt wheel 2, force belt wheel 2 and roller 3 on the friction face 8 that forms between first end face 22 and second end face 34, to produce end-face friction, promptly on the end face between belt wheel 2 and the common friction face 8 that roller 3 contact because of the generation end-face friction that rubs.
The described slip gear 10 of the utility model embodiment is by axle 1 is fixing, belt wheel 2 and roller 3 are enclosed within on the fixing axle 1, elastic force by springing 5 makes roller 3 and belt wheel 2 closed contacts again, when transmitting device 4 drives belt wheel 2 rotations, belt wheel 2 rotates always, second end face 34 of roller 3 is to be attached on first end face 22 of belt wheel 2, by producing 3 rotations of end-face friction driving rolls between first end face 22 and second end face 34.
Part clamp (figure does not show) is placed on the roller 3, then roller 3 rotating drive part clamps motion, when part clamp is stopped on automation transmission production line sense of motion when stopping, produce friction force between part clamp and the roller 3, this friction force is greater than the end-face friction between belt wheel 2 and the roller 3, consequently part clamp and roller 3 stop motion together, and belt wheel 2 is rotated further under the driving of transmitting device 4, formed the friction force when rotating between belt wheel 2 and the roller 3, by contrast, the friction force of this moment has reduced a lot, frictional loss has reduced a lot, the described slip gear 10 of the utility model embodiment has also improved the service life of structure when reducing frictional loss.
The utility model embodiment end-face friction idler wheel mechanism 10, its friction face 8 is at the end face of belt wheel 2 with roller 3, and the contact surface of roller 3 and belt wheel 2 and axle 1, because belt wheel 2 and roller 3 show mainly that with the frictional loss of axle 1 internal diameter of belt wheel 2 and roller 3 becomes big, and the top of axle 1 wearing and tearing, but such variation can not influence belt wheel 2 and the normal rotation of roller 3 on axle 1, therefore under situation about not being destroyed, service life is by unlimited lengthening in theory, and being the end face that belt wheel 2 contacts with roller 3, the result that the end-face friction between belt wheel 2 and the roller 3 causes all produces wearing and tearing, and when not needing product clamper to stop, belt wheel 2 and roller 3 are rotating drive product clamper transmission together, between have friction, but this frictional loss is very little.
On the other hand, when the needs product clamper stops, belt wheel 2 is rotated further under the drive of transmitting device, 3 on roller stops with product clamper, at this moment produced the friction between belt wheel 2 and the roller 3, but the time of Ting Liuing is not long like this, therefore the actual frictional loss that produces does not have much, after producing wearing and tearing after the long-time use, be the end face of belt wheel 2 and the end wear of roller 3, that is to say that the gap between belt wheel 2 and the roller 3 becomes big, be close on the belt wheel 2 but remain, just end wear at the effect bottom roller 3 of spring 5.Belt wheel 2 rotates under the driving of transmitting device 4, wearing and tearing rear roller 3 still can by and belt wheel 2 between friction force rotation, so just can guarantee that roller 3 can use for a long time, increase its service life.
As shown in Figures 2 and 3, the described belt wheel 2 of the utility model embodiment is provided with groove 21, transmitting device 4 is arranged in this groove 21 and can moves along this groove 21, thereby makes transmitting device 4 more stable in rotating process, and transmission processing parts and anchor clamps location are more accurate.
As shown in Figures 2 and 3, the described roller 3 of the utility model embodiment comprises end 31 and afterbody 32, and the diameter of this afterbody 32 is less than end 31, thereby is convenient to place on afterbody 32 part, anchor clamps etc.The described roller of the utility model embodiment 3 ends 31 are formed with a platform 33 that is lower than end 31, and the roller 3 and the contact surface of belt wheel 2 are reduced greatly, can reduce the end-face friction between roller 3 and the belt wheel 2.
Shown in Fig. 1-5, the arranged outside of described roller 3 of the utility model embodiment and belt wheel 2 has block piece 6.This block piece 6 can stop roller 3 to produce displacement in rotation process, it is more accurate to make roller 3 transmit part etc. in rotation process, and an end of springing 5 is connected on this block piece 6, the other end is connected on the end face in described gap 35, thereby springing 5 can be fixed in the roller 6; Described block piece 6 outsides also are provided with elasticity gripping mechanism 7 simultaneously, and belt wheel 2, roller 3 and block piece 6 etc. are fixed together.The utility model can also include an end with described axle, the diameter of this end is greater than remainder, during use, belt wheel 2, roller 3 can be sheathed on the axle 1 from the little end of diameter, add block piece 6 again in roller 3 outsides, at the flexible gripping mechanism 7 of block piece 6 arranged outside, this structure can also add a block piece 9 in the big side of axle 1 diameter, this block piece can be selected mother Luo or pad etc., plays better barrier effect.
The described slip gear 10 of the utility model embodiment, its described transmitting device 4 is belt, chain or carrier bar, especially be good with round belt and flat belt, it can reduce the friction force of itself and groove 21 in the transmission of rotation process, improves the service life of belt.
The described roller 3 of the utility model embodiment can be a plurality of, only need the afterbody 22 of lengthening belt wheel 2 to get final product, again a plurality of rollers 3 are placed on the belt wheel afterbody 22, add block piece 6 in roller 3 one sides in the outside again, at the flexible gripping mechanism 7 of block piece 6 arranged outside, thereby a plurality of rollers 3 can carry more anchor clamps etc., increase work efficiency.
