Abstract

The utility model relates to a textile machinery component, in particular to a top roller bearing of a spinning machine, which can be turned over for use and is an integrated component. The top roller bearing comprises two bearing heads 1 and a holding block 2; wherein, the two bearing heads 1 are symmetrically arranged in the axial direction; and the axial center a of the holding block 2 is arranged eccentrically opposite to the axial centers b of the two bearing heads. The utility model has the advantage that when the yarn stroke on the bearing heads is worn and can no longer be used, the top roller bearing can be removed, overturned and reassembled for use, so that the yarn stroke can be moved and the yarn stroke at the single side is transformed into two yarn strokes. And therefore, the service life is doubled.

Description

A kind of spinning machine upper roller bearing of turning use

Technical field

The utility model relates to a kind of spinning machine upper roller bearing of textile machine parts, particularly a kind of turning use.

Background technology

The spinning machine upper roller bearing is to be used to a kind of top roller bearing of spinning on the spinning machine.During work, yarn, is finished the spinning process of rove to spun yarn to another rubber roll from a rubber roll.Its top roller bearing is made up of bearing and rubber roll cover, and the rubber roll cover is sheathed on the outside of bearing.Upper roller bearing is that twin shaft is taken the lead, and also is two top roller bearings.The connection axle journal at two bearing head middle parts is called the gripping shelves, and it grips shelves length L and is generally 16mm.When yarn was passed by rubber roll, the amplitude of oscillation of teeter was called the yarn traverse on its rubber roll.Upper roller bearing is the slub two-yarn line simultaneously, and the yarn traverse of a side is A, and the yarn traverse of opposite side is B.

At present, upper roller bearing is symmetry axially, and promptly twin shaft is taken the lead and all is symmetrical arranged with the axial centre that grips the relative upper roller bearing of shelves.Only have yarn traverse A, a B on the rubber roll of both sides respectively, and lay respectively at the middle part of both sides rubber roll.After using a period of time, will wear and tear and bad in the position of yarn traverse A, B on its rubber roll.Yarn traverse A, B are generally 8-10mm, and the length of one-sided rubber roll is 23mm, and all the other all are wasted.In a single day rubber roll is worn, and just must change again, so its service life is low, waste is serious.

Summary of the invention

Technical barrier to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of spinning machine upper roller bearing of turning use is provided.

Technical solution of the present utility model is, is provided with two bearing heads and one and grips shelves, and two bearing heads axially are symmetrical arranged, and it is characterized in that: the eccentric setting of axial centre that grips relative two bearing heads of axial centre of shelves.

The eccentric distance d of the axial centre of relative two bearing heads of axial centre of gripping shelves is 4-7mm.

The advantage that the utility model is compared with prior art possessed is: can reverse end for end to overturn and use, one-sided traverse becomes two by one, and double service life.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is rubber roll and the traverse position view behind the utility model assembly glue roller shell;

Fig. 3 for Fig. 3 overturn the tune after rubber roll and traverse position view;

Fig. 4 is the rubber roll structural representation of background technology.

Number in the figure: 1-bearing head, 2-grip shelves, A-yarn traverse, and B-yarn traverse, d-eccentric distance, L-grip shelves length, and a-grips the axial centre of shelves, the axial centre of two bearing heads of b-.

The specific embodiment

Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:

The as a whole assembly of the utility model, it is provided with two bearing heads 1 and 2, two bearing heads 1 of gripping shelves axially are symmetrical arranged, and grips the eccentric setting of axial centre b of relative two bearing heads of axial centre a of shelves, and its eccentric distance d is 4-7mm.

During work, the utility model is that support card is held on the spinning machine to grip shelves 2, and it grips the shelves length L and is generally 16mm.After work a period of time, as the yarn traverse A on the bearing head 1, when the wearing and tearing of B place can not be used, the utility model can be taken off to refill after upset is reversed end for end and join use, make yarn traverse A, B displacement, thereby make bearing one-sided yarn traverse A, B become two by one, be doubled service life.

Claims

1, a kind of spinning machine upper roller bearing of turning use is provided with two bearing heads and gripping shelves, and two bearing heads axially are symmetrical arranged, and it is characterized in that: the eccentric setting of axial centre that grips relative two bearing heads of axial centre of shelves.

2, the spinning machine upper roller bearing of a kind of turning use as claimed in claim 1 is characterized in that: the eccentric distance d of the axial centre of relative two bearing heads of axial centre of gripping shelves is 4-7mm.
