Abstract
The invention relates to a key bar type pneumatic shaft. The key bar type pneumatic shaft has a cylindrical body, the body is provided with a mesopore penetrating through two ends of the body along the shaft axis direction of the body, the outer peripheral surface of the body is movably provided with a plurality of uniformly-arrayed key bars, and the key bars can protrude along the radial direction of the body when a tank gas in the mesopore is pressurized. The key bar type pneumatic shaft has a simple structure, can cooperate with a shaft sleeve to realize the application to stripping, printing, re-reeling, coating, applying, bag making, papermaking or other relevant reeling and sending machines having high torques and high bearing weights.
Description
Technical field
The present invention relates to a kind of key-strip type airpressure axle.
Background technique
The rolling of roll product and unreel the normally used mechanical type clamp shaft that has, the common axis body of this axle is larger, and weight is heavier, operating efficiency is low.For this reason, in the urgent need to a kind of not fragile, use extensively the airpressure axle of low cost of manufacture.
Summary of the invention
The object of the invention provides a kind of key-strip type airpressure axle.
For achieving the above object, the technical solution used in the present invention is:
A kind of key-strip type airpressure axle, it has a columniform body, offer the mesopore that runs through two ends along its direction of axis line on the described body, be movably set with several key bars arranged in a uniform on the outer circumferential face of described body, described key bar can the radial direction along described body be given prominence to when described mesopore tank gas pressurized.
Preferably, the material of described body is No. 45 steel.
Preferably, the material of described body is aluminum alloy.
Further preferably, when the length of described body during less than 1500mm, the material of described body is aluminum alloy.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
The present invention is simple in structure, and the fitted shaft sleeve can be applicable to that the higher itemize of torsion and load capacity, printing, rewinding, coating, applying, bag, papermaking or other are relevant to be batched and send machinery and be used in conjunction with.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.
Wherein: 1, body 2, mesopore 3, key bar.
Embodiment
The invention will be further described below in conjunction with drawings and Examples:
A kind of key-strip type airpressure axle as shown in the figure, it has a columniform body 1.Wherein: offer the mesopore 2 that runs through two ends along its direction of axis line on body 1, be movably set with several key bars 3 arranged in a uniform on the outer circumferential face of body 1, key bar 3 can the radial direction along body 1 be given prominence to when mesopore 2 tank gas pressurized.
In general, the material of body is No. 45 steel, and when the length of body 1 during less than 1500mm, the material of body 1 is that aluminum alloy is more suitable.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
