Description
Technical field
The present invention relates to a kind of Galette unit that is used for guiding and carrying the long filament in advancing by claim 1 preamble.
Background technology
Such Galette unit is known, is used for guiding and carry one filament or the long filament group in spinning equipment, so that for example extract long filament or elongate filaments for example out from spinning-nozzle.Here godet roller is equipped with independent drive unit usually, and it drives the driving shaft that is connected with the godet roller overcoat.Usually in the zone of drive shaft bearing between godet roller overcoat and power-jdriven gear, as for example by known to the DE 37 01 077.
Because the current common long filament speed of service that is much higher than 1000m/min reaches very high driving rotating speed, this big load also causes heat energy higher in the power-jdriven gear except that the bearing heating that causes being caused by bearing friction.At this moment produce such problem, promptly most of heat energy of power-jdriven gear enters in the bearing.This phenomenon causes undesirable temperature difference in the rolling bearing, make with rolling bearing that driving shaft is connected in encircle and have the temperature higher than the outer shroud that is bearing in the rolling bearing on the bearing.Cause the undesirable fluctuation of bearing pre-fastening thus.The reflection in the Galette unit of godet roller overcoat heating of this problem is stronger, because much bigger by the heat energy of driving shaft transmission.
On the machine wall of making housing of the direct processing in known godet roller middle (center) bearing hole at support.But this structure is not suitable for being used for preventing that rolling bearing is overheated.
By US4,822,972 known another kind of Galette units, wherein driving shaft is bearing in the bearing by at least one rolling bearing.Bearing has many cooling ducts, and they particularly cool off the perimeter of rolling bearing, and the heat that is sent by the rolling bearing outer shroud on the bearing by this structure medium that is cooled basically receives and discharges.But only increased the weight of the problem of the temperature difference between interior ring of rolling bearing and the outer shroud thus.
Summary of the invention
Therefore the objective of the invention is, create the Galette unit that is used for carrying and guiding at least one long filament in advancing that a kind of tape spool that starts described type holds cooling device, it is overheated that this bearing cooling device prevents on the one hand, impels the homogenising of rolling bearing internal operation temperature on the other hand.

For the heat conduction between the air ring that rotates and the fixing cooling muscle matrix, the cooling rod of many projectioies is installed on air ring and cooling muscle matrix, they are overlapped and don't hinder and rotatablely move, and cause big as far as possible heat transfer area thus.
In order to strengthen the radiating surface of cooling body on circumference, cooling body is advantageously done to such an extent that have a cooling muscle.
Breach when the cooling muscle particularly is set on the circumference of air ring on the cooling muscle causes producing the cooling blast that eddy current is arranged that helps cooling off when air ring is followed the driving shaft rotation.
Not only be confined to Galette unit by the structure of bearing cooling device of the present invention with a bearing.Particularly can reach than higher pretightning force stability by the cooling device that is equipped on rolling bearing respectively when the rolling bearing of pretightning force supports with two tape spools on the contrary at driving shaft.When rolling bearing is obliquely installed in the rolling bearing ring and outer shroud between temperature difference cause the variation of angle position, thereby the shortcoming that causes (adding) pretightning force can be avoided.Prevent change in angular position as long as directly dispel the heat on the ring in rolling bearing, axial pre tightening force remains unchanged basically so.
Do not influence each other for the cooling device that prevents rolling bearing does not produce, cooling body preferably be contained in the ring on the side outside the dead eye, especially the rolling between rolling element and interior ring contacts on the side.
Particularly can advantageously use cooling fluid towards the cooling body of drive unit one side, especially use cold air around spray, cold air produces by the cooling fluid generator on drive unit one side.This cooling fluid generator at first is used for the cooling power drive unit.But cold air or cooling fluid also can advantageously lead on the cooling body that is contained on the Galette unit projecting end by the cooling duct.
Be particularly suitable for by Galette unit of the present invention, be used for heating the long filament that outside godet roller, puts guiding.Be provided with a heater that is used for the heated godet overcoat, it is installed in the annular chamber that forms between godet roller overcoat and the driving shaft for this reason.Here advantageously directly in rolling bearing, receive on the ring and discharge to interior heat by cooling body to driving shaft output.
