Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a modification of a bearing for a spinning rotor in an open-end spinning machine. For example, West German Patent No. 2 (33555
It is known to store lubricating oil in a tank separate from the bearing and to communicate this oil by means of a hose with a nozzle inserted into the bearing housing. In this case, a wick that reaches the i-tank passes through the hose, and oil drips onto the shaft from the tip of the wick that is 4 times smaller than the nozzle, supplying oil to both WaV end bearings. This/) J11&, The refueling kidney of the a receiver is the core 7) Cross-sectional area.

Determined by the head difference between the tank and the shaft. Structure of D bearing with lubrication device and 1! Preparation is expensive and troublesome, and requires space for a tank outside the bearing-housing D.

Similarly, in the spinning rotor bearing known from West German Patent Publication No. 2840657, two rollers are held axially in a bearing pool with nine bearings, and the bearing bush is surrounded by a bearing housing while maintaining an annular space. A special intermediate sleeve is inserted into the annular space, a wheel bearing bushing is placed in the intermediate sleeve, and the intermediate sleeve is held in the bearing housing by elastic supports disposed at both axial ends. The intermediate pukue, which is made longer in the axial direction than the bearing pukue and rests on the bearing bush on both ends, stores lubricating oil and mixes the oil mist into the air circulation R, which occurs during operation, to lubricate the rolling bearing. This means that when inserting the intermediate sleeve between the bearing bush and the bearing housing, the diameter of the bearing opening must be increased, and the bearing housing must be inserted into the holder of a standardized machine. will no longer be possible.

This invention was developed for the purpose of storing lubricating oil so that rolling bearings can be refueled during long operating hours without any additional external installation and without increasing the outer diameter of the bearing housing. There are nine.

This problem can be solved by the invention set forth in claim <1). That is, by closing the annular wall between the bearing bushing and the bearing housing in the axial direction with the end wall.
This is used as a storage chamber for lubricating oil, thereby avoiding the external KvlJk of the bearing and keeping the diameter of the bearing bushing and bearing nozzle constant. Oil can be constantly supplied to the grease in the rolling bearing through the hole in the bearing bushing, and depending on the shape and position of this hole, there is also a means for guiding the oil (core, porous body, etc.) that reaches the grease in the rolling bearing through this hole. Therefore, it is possible to control the supply of oil to the rolling bearings.

Spinning rotor bearing 21 West German Patent Publication No. 211390 in which the two rollers are paper bearings and the space between both bearings in the bearing housing that holds the rotor shaft is filled by inserting an intermediate punch to fill the space.
It is known as No. 5. In this case, an annular space is formed between the outer periphery of the bushing and the inner periphery of the bearing housing, and between the inner periphery of the bearing bush and the outer periphery of the shaft. The force on the outside of the housing's oil filler port is
Grease is pushed into the annular space with both axial ends closed, and when the outer annular space is full, the radial passage force 1 in the intermediate bushing is applied to the inner annular space, and four colors of grease are applied to both axial ends. Oil is supplied to the bearing on both rollers through a narrow annular gap between a certain bushing and the shaft. In this case, the round grease in the inner annular space is simultaneously sprayed in the form of a jet due to the force of the gap between the two rings 911 in the axial direction.
\ru. Applying force 1 and lubricating the bearing to the rollers, 1. If you push the grease out and 6. in that way, it will just happen, and even if there is grease in the annular space, it will not be pushed in by external force. Since paddy is not oiled, it is different from the present invention in which oiling is always carried out.

Claim (2), f) By performing 41K, the rollers lubricated with grease can appropriately control and adjust the supply of oil to the paper bearing.

Nishi l! In 41 Publication No. 293,403, the derivative is divided into bearings and supplied with oil to the grease, which is saturated with greasy oil and maintains a completely lubricating property at all times. As stated in claim (3) above, by arranging the S conductor in the enclosing space, a. The oil can be returned from the bearing pukuyu to the oil storage body in the storage chamber.

The volume of the storage chamber/)1 annular space/)The length in the Jl11 direction can be determined by the arrangement of the end walls. The elastic support that holds the bearing in the bearing housing can be used as a closed end wall at both ends of the annular space, and it can also be used as a storage chamber for lubricating oil along the entire axial length of the annular space. be. However, even if it is formed from a part of the annular space like a storage room,
It is possible to store enough oil to operate the bearing for a considerable period of time without relubrication. Therefore, if implemented as stated in claim (4).

By simply arranging an additional end*, a storage chamber can be formed as a part of the annular space, and this end wall can be colored.Claim <5)
K If arranged as described above, the part of the round annular space that is not a storage chamber will be assigned to the rolling bearing on the rotor side and the backing D will be placed outside 1-? .

An advantage arises in that the flywheel side rollers can be used as a part of the bypass path to maintain the same pressure as the outside of the backing assigned to the paper bearing.

The present invention will be described below with reference to an illustrated embodiment.

In Fig. 1, l indicates the holder of the open two-rotor spinning machine, into which the bearing extruder, including the bearing for the spinning rotor, can be inserted and removed. It is fixed to . Two annular supports J and II made of elastic material are fitted into both ends of the bearing housing, and the bearing pin is fixed between the inner peripheries of the two supports.

Bearings 6 and 7, which have both rollers, are lubricated with grease, and this grease is always in an oil-saturated state, that is, in a state of high oil lubricity, by the oil (equivalent to Grease D base oil) supplied from the storage chamber/41. It is maintained. Oil 4 to both rollers bearing 6.7
I: Inside the enclosed space 1, a shaft t4I: a tubular enclosing means, 7) a lubricating oil derivative, is fixedly inserted between the grease coda and λdaD as an oil guide means. *As can be seen in Figure 3, the kit conductor is a strip material, preferably a metal strip, made of two or more turns in a spiral shape, and the outer turn K is a plug.
There is a hole facing the inside, but there is no hole on the inside. Therefore, between the inner and outer windings, a long sword is opened radially outward and Kl is inserted between both ends of the derivative. There is a spiral-shaped capillary gap that extends. The m conductor n is elastic and has a diameter such that it comes into close contact with the inner surface of the bearing. In the nine drawings shown here, they are separated by a large distance to make it easier to read, but the actual drawings are slightly different from this. - Hole 2 from t&gt; in the capillary gap of the conductor
