Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1:
A kind of idler wheel shaft assembly having sudden-stop function, for being mounted in roller-way bracket 1.As shown in Figure 1, roller shaft group
Part includes roller shaft 2, and roller shaft 2 passes through band retaining ring bearing 3 and connect with roller-way bracket 1.Between roller-way bracket in roller shaft 2
It is fixed with the idler wheel 4 of transmitting workpiece.Fixed reliable between roller shaft and idler wheel in order to make, idler wheel 4 passes through spring catch 5 and roller shaft
2 is fixed.Sprocket wheel 6 is provided in roller shaft 2, sprocket wheel 6 is located at the side of roller-way bracket 1, and sprocket wheel 6 is dynamic by chain 14 and outside
The output axis connection of power equipment.It include a bushing 7 between sprocket wheel 6 and roller shaft 2.In the present embodiment, bushing 7 uses copper alloy material
Matter.It is reliable in order to make to connect between bushing and roller shaft, keyway, roller shaft 2 and lining are provided in roller shaft 2 and bushing 7
Set 7 is connected by key 8.Friction plate is provided in sprocket wheel two sides roller shaft 2.9 both ends of the surface of friction plate on the left of sprocket wheel
It is abutted respectively with roller shaft 2 and sprocket wheel 6,10 end face of friction plate on the right side of sprocket wheel is abutted with sprocket wheel 6.In order to guarantee to rub
Connect more reliable between piece and roller shaft, the friction plate 10 on the right side of sprocket wheel is connect with key 8.Spring is arranged in roller shaft 2
11, one end of spring 11 is pressed on 10 end face of friction plate on the right side of sprocket wheel.In order to facilitate the elastic force of adjustment spring, roller shaft
2 end is provided with adjusting nut 12, and 12 side of adjusting nut is provided with washer 13, and one end of spring 11 is abutted with washer 13.
By adjusting adjusting nut, carry out adjustment spring to the extruding force of friction plate, so that the maximum static friction between friction plate and sprocket wheel
Power is less than the force of sliding friction between workpiece and idler wheel, and the force of rolling friction being greater than between workpiece and idler wheel.In the present embodiment,
Friction plate uses nylon material.
Before the device, first according to the force of sliding friction between workpiece to be transmitted and idler wheel come the elastic force of adjustment spring.
By adjusting nut come the decrement of adjustment spring, and then change spring and power compressed to friction plate, need to guarantee friction plate with
Maximum static friction force between sprocket wheel is less than the force of sliding friction between workpiece and idler wheel, and the rolling being greater than between workpiece and idler wheel
Kinetic force of friction, i.e. workpiece have force of rolling friction in transmission process between workpiece and idler wheel, force of rolling friction is less than friction plate
Maximum static friction force between sprocket wheel, therefore after sprocket wheel rotation, sprocket wheel drives roller shaft to rotate by friction plate, roller shaft
Idler wheel rotation is driven, and then realizes the transmission of workpiece above idler wheel；When workpiece reaches aiming station, workpiece is by aiming station
Stop, the rolling friction between workpiece and idler wheel is changed into sliding friction, since the force of sliding friction between workpiece and idler wheel is big
Maximum static friction force between friction plate and sprocket wheel, therefore, although sprocket wheel continues to rotate, friction plate and roller shaft stop
Rotation, and then idler wheel stops operating, to reduce the abrasion between idler wheel and workpiece.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
