Description
Technical field
A kind of transmission group is the utility model is related to, particularly a kind of stepless adjustable frictional drive group.
Background technology
In automatic conveying equipment, there is a kind of mode of movement to be referred to as " stacking roller ", this roller-way can both realize work
The purpose that part freely transmits on roller-way, it conveying roller can be stalled in the case where workpiece is blocked again, avoid wearing workpiece
Contact surface.
A critical component in this roller-way structure is exactly frictional drive group, and conveying power is needed by frictional drive group
Roller is passed to, to ensure that roller can both have enough conveying power, can be stalled again in the case of being hampered.Its key is exactly
Frictional force（That is driving force）Regulation it is appropriate, this requires frictional drive group can subtly regulating friction force, and requiring
It is lockable after easy to adjust, regulation.
The structure that conventional frictional drive group has is coarse and crude, is not easy to adjust, some regulation steppings（4-6 shelves）, cause
Frictional force regulation is not fine enough, can not often meet the needs of under a certain particular case.
The content of the invention
The purpose of this utility model be to provide it is a kind of it is simple in construction, easy to operate, compact-sized, cost is cheap, regulation is simple
Single and lockable stepless adjustable frictional drive group, overcome the deficiencies in the prior art.
Stepless adjustable frictional drive group of the present utility model, including power transmission shaft, outside is fixed with power transmission shaft and is processed
There is the trapezoidal swivel nut of trapezoidal thread, trapezoidal nut is connected with trapezoidal swivel nut by trapezoidal thread, and trapezoidal nut is located in adjusting set
And spline is provided between adjusting set endoporus, groups of springs is provided between inner side and the termination of trapezoidal nut in one end of adjusting set,
External friction disk is fixed with power transmission shaft, driving gear is set with external friction disk, is provided between driving gear and adjusting set interior
Frictional disk, driving gear are clamped between external friction disk and internal friction disc, pass through conjunction gear between external friction disk and internal friction disc
Connection, connected between internal friction disc and the end face of adjusting set by neck on clamp and internal friction disc end face, driven gear with
Driving gear is intermeshed.
Stepless adjustable frictional drive group of the present utility model, trapezoidal swivel nut are fixed on power transmission shaft, trapezoidal nut and ladder
Shape swivel nut engages, and adjustment seat passes through chute with trapezoidal nut outer wall（Spline）Connection, trapezoidal nut can be in adjustment seats axially
It is mobile, and trapezoidal nut end is provided with groups of springs, and spring press against adjustment seat, and adjustment seat press against internal friction disc and pass frictional force
Driving gear is passed, driving gear delivers torque to driven gear again, and driven gear is arranged on the end axle of roller-way, so as to reach
The purpose rotated to driven roller.Here the regulation of frictional force is realized by trapezoidal thread group, and operating personnel hold
Firmly adjustment seat, along drive axis direction, pull, make in the clamp disengaging of adjustment seat termination to the direction away from driving gear
The neck of frictional disk, then rotates adjustment seat, you can adjusts the size of spring force.After regulation, adjustment seat is discharged, makes its heavy
Newly it is connected with internal friction disc, regulation finishes.It is easy to adjust quick, manipulate simply, without using other instruments.It is compact-sized, zero
Part uses die casting, greatly reduces manufacturing cost.Take trapezoidal thread to be adjusted, there is stepless adjustable performance, can
To adjust out more accurate careful power output, the scope of application is wider.All structural members nonmetallic materials can be used to make, whole
Body weight is very light, and operation is flexible, noise is low, long lifespan.
Brief description of the drawings
Fig. 1 is the utility model embodiment structural representation.
Embodiment
As shown in Figure 1：Stepless adjustable frictional drive group of the present utility model, including the power transmission shaft to connect with drive mechanism
1, on power transmission shaft 1 being fixed with outside by trapezoidal swivel nut steady pin is machined with the trapezoidal swivel nut 3 of trapezoidal thread, trapezoidal nut 5
It is connected with trapezoidal swivel nut 3 by trapezoidal thread.
Trapezoidal nut 5 is located in adjusting set 7 and spline 4 is provided between the endoporus of adjusting set 7（Sliding groove structure）, adjusting set 7
One end on the inside of and the termination of trapezoidal nut 5 between be provided with multigroup groups of springs 6, each group groups of springs is circumferentially uniformly distributed.
External friction disk 10 is fixed with by external friction disk steady pin 11 on power transmission shaft 1, master is set with external friction disk 10
Moving gear 13, is provided with internal friction disc 9 between driving gear 13 and adjusting set 7, driving gear 13 is clamped in external friction disk 10 and interior
Between frictional disk 9.
Connected between external friction disk 10 and internal friction disc 9 by conjunction gear 12, the end face of internal friction disc 9 and adjusting set 7 it
Between connection, driven gear 14 and driving tooth be mutually inserted by the neck on the clamp 8 and internal friction disc end face of the end face of adjusting set 7
The intermeshing of wheel 13, driven gear 14 are arranged on the spindle nose 15 of transfer roller termination.
Stepless adjustable frictional drive group of the present utility model, trapezoidal swivel nut 3 are fixed on power transmission shaft 1, trapezoidal nut 5 with
