Abstract
The invention provides a roll shaft lubricating structure which comprises a roll shaft and a pair of roll shaft supports pivoted at two ends of the roll shaft, wherein a pair of flexible enclosed rings is used for sealing a ring-shaped space between shaft holes, accommodating the roll shaft, of the roll shaft supports and the roll shaft, and the ring-shaped space is full of water; and semiconductor refrigeration films or refrigeration pieces are arranged on the inner walls of the shaft holes. The roll shaft lubricating structure has the advantages that the water in the ring-shaped space ices through the semiconductor refrigeration films or the refrigeration pieces, and the roll shaft can slide on a sliding plane formed by the ice; and as the water in the ring-shaped space can be supplemented, the ice layer in the ring-shaped space is always formed, and accordingly, the shaft holes avoid wear.
Description
Technical field
The present invention relates to the textile manufacturing machine apparatus field, especially, is a kind of wear-resistant roll shaft lubricating structure.
Background technique
Comprise a large amount of component that rotate in the conventional machinery, such as rotor of various transmission shafts, main shaft, motor and steam turbine etc., be referred to as solid of rotation.The pressure that bearing is produced is the same when not rotating solid of rotation when rotation in ideal conditions, and such solid of rotation is the solid of rotation of balance.But the various solid of rotation in the engineering, because the error that produces in the inhomogeneous or blank defective of material, processing and the assembling, even when design just have the many factors such as asymmetrical geometrical shape so that solid of rotation is when rotated, the centrifugal inertia force of each small particle generation can not be cancelled out each other it on, centrifugal inertia force is applied on machinery and the basis thereof by bearing, cause vibration, produced noise, accelerate bearing wear, shorten mechanical life, can damage incidents when serious.Any rotor is around its axis rotation the time, owing to the non-uniform mass with respect to axis produces centrifugal force.This uneven centrifugal action can cause vibration on rotor bearing, produce noise and accelerate bearing wear, so that have a strong impact on performance and the life-span of product.Particularly in the textile manufacturing machine that is widely used the solid of rotation bearing, the dynamic equilibrium problems that bearing wear causes is perplexing the raising of textile quality always.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of roll shaft lubricating structure, this roll shaft lubricating structure can keep roll shaft to remain at the central position of roller support.
The technical solution adopted for the present invention to solve the technical problems is:
This roll shaft lubricating structure comprises the pair of rolls shaft stool at roll shaft and the described roll shaft of hub setting two ends, axis hole and the annular space between the described roll shaft that described roller support holds described roll shaft are sealed by the pair of flexible closed loop, be full of water in the described annular space, be provided with semiconductor refrigerating sheet on the inwall of described axis hole, the two ends of described roll shaft are provided with the taper registration holes, the vertex of a cone of described taper registration holes is arranged on the axle center of described roll shaft, be provided with the contraposition cone that adapts with described taper registration holes on the described roller support, described contraposition cone is controlled with separating by a telescoping member with the combination of described taper registration holes.
As preferably, the axial wall of described roll shaft and the inwall of described axis hole distance are between 0.2mm to 1mm.
As preferably, be provided with the moisturizing passage to described annular space supplementing water in the described axis hole.
As preferably, described roll shaft is positioned on the axial wall at two ends of described axis hole and all is coated with heat insulating coat.
As preferably, be provided with the radiating structure of the described semiconductor refrigerating sheet heat dispersing surface of contact in the described roller support.
The invention has the advantages that: this roll shaft lubricating structure utilizes described semiconductor refrigeration film or refrigerating sheet to make to be full of the ice that water is formed in the described annular space, the slip surface that utilizes ice to form, described roll shaft is slided, because the water of described annular space can replenish, therefore, ice sheet in the described annular space can form all the time again, makes described axis hole never wornout.
