Described elongated hole mate, and with described elongated hole matched in clearance.This design, can be fully on the premise of ensureing this fricting strip activeness
Retrain the deformation direction of this fricting strip, make this fricting strip only along the direction radial enlarging of described differential slip ring inner surface, reduce described
The transmission loss rate of rubber pneumatic bag the blowing pressure.
Further, the fricting strip material used by above-mentioned slip shaft is the Corii Bovis seu Bubali that coefficient of friction is bigger.Increasing rubbing surface
Amass and in the case of material friction coefficient, the winding tension that above-mentioned slip shaft can be provided by is under original structure and material context
220%.
Further, the differential slip ring of above-mentioned slip shaft includes internal ring and outer shroud；This internal ring is placed in this outer shroud matchingly
In ring cavity, and its outer surface is provided with multiple eccentric grove；This outer shroud is equipped with conical through-hole corresponding to the position of each eccentric grove, and
This conical through-hole collar extension diameter is less than its internal orifice diameter；It is provided with rolling in the cavity that above-mentioned eccentric grove and above-mentioned conical through-hole are formed
Pearl, and this ball diameter is more than conical through-hole collar extension diameter；Above-mentioned ball relatively rotating along eccentric with described internal ring and outer shroud
The bottom land of groove rolls around, and the conical through-hole from above-mentioned outer shroud is prominent outward or in retraction eccentric grove, reaches compel folder and put
The purpose of pine rolling material material pipe.
Further, above-mentioned slip shaft main shaft is nested with for multiple differential slip rings；This differential slip ring be nested with quantity according to institute
The on-demand increase and decrease of width of rolling material, the demand of flexible adaptation different in width rolling material.
This utility model also proposes a kind of cutting and rewinding device for above-mentioned technical problem, including slippage as above
Axle.
In sum, the slip shaft that the utility model proposes and cutting and rewinding device, some materials can be met to big rolling
Tension requirements, and simple in construction, convenient maintenance and maintenance, use cost is low.
