Abstract
The utility model relates to a component, in particular to a top roller bearing with double strokes. The top roller bearing comprises a bearing 1 and roller sleeves 2, wherein the bearing 1 is provided with two bearing heads and a holding retainer 3; and the roller sleeves 2 are respectively sleeved on the two bearing heads. The top roller bearing is characterized in that the length of the holdingretainer 3 is 20-30mm; the cylindrical journal surface of the holding retainer 3 is provided with knurling overlapping curves or annular groove markings. The top roller bearing has the advantages that after being used for some time, the top roller bearing can be reused after axial displacement, the unilateral yarn stroke is displaced, changing from one to two, the service life is doubled, the axial stability is realized, and the reliability is good.
Description
Technical field
The utility model relates to a kind of textile machine parts, particularly a kind of top-roller leather roller bearing that has two traverses.
Background technology
The spinning machine top-roller leather roller bearing is to be used to a kind of roller bearing of spinning on the spinning machine.During work, yarn, is finished the spinning process of rove to spun yarn to another roller from a roller.Top-roller leather roller bearing is made up of bearing and roller cover, and the roller cover is sheathed on the outside of bearing.Top-roller leather roller bearing is that twin shaft is taken the lead, and also is two roller bearings.The connection axle journal at two bearing heads middle part is called and grips shelves, and it grips shelves length L and is generally 16mm, and the axle journal that grips shelves is smooth axle journal.During work, top-roller leather roller bearing is gripped by the gripping of the reel cage on spinning machine bayonet socket and is fixed.The width that general reel cage grips bayonet socket equates with the width that the roller bearing grips shelves, is 16mm, to keep the axial stability of roller bearing.
When yarn was passed by roller, the amplitude of oscillation of teeter was called the yarn traverse on its roller.Two side bearings of top-roller leather roller bearing spin an one thread respectively only, also, only have a yarn traverse a on the roller of both sides respectively, and lay respectively at the middle part of both sides roller, see Fig. 5.After using a period of time, will wear and tear and bad in the position of the yarn traverse on its roller.Yarn traverse a is generally 8-10mm, and the length of one-sided roller is 23mm, and all the other all are wasted.In a single day roller 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 top-roller leather roller bearing that has two traverses is provided, and the utility model is compared with the top-roller leather roller bearing of routine, has double service life.
Technical solution of the present utility model is, comprise bearing 1 and roller cover 2, bearing is provided with two bearing heads and gripping shelves 3, be with roller cover 2 on two bearing heads respectively, it is characterized in that: the length L that grips shelves 3 is 20-30mm, and the cylindrical journal surface that grips shelves 3 is provided with annular knurl reticulate pattern or cannelure line.
The length L that grips shelves 3 is 26.5mm.
The advantage that the utility model is compared with prior art possessed is: after using a period of time, can will re-use after the utility model axial displacement, make one-sided yarn traverse transposition, become two by original one, double service life, and axially stable, good reliability.

Number in the figure: 1-bearing, 2-roller cover, 3-grip shelves, and 4-grips card a-yarn traverse, and " the yarn traverse, L-grips shelves length for a '-yarn traverse, a.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
The utility model comprises bearing 1 and roller cover 2, and bearing 1 is provided with on two bearing heads and 3, two bearing heads of gripping shelves and is with roller cover 2 respectively.The length L that grips shelves 3 is 20-30mm, and present embodiment is 26.5mm.The cylindrical journal surface that grips shelves 3 is provided with annular knurl reticulate pattern or cannelure line, sees Fig. 1, Fig. 2.
During work, the utility model is that support card is held on the gripping card 4 of spinning machine reel cage to grip shelves 3.
When bringing into use, gripping card 4 can be gripped on a side axial end that grips shelves 3, right side axial end as shown in Figure 3, this moment, yarn traverse a ' was partial to the right side of roller cover 2.After using a period of time, when roller cover 2 wearing and tearing that yarn traverse a ' locates can not be used, the utility model can be carried out displacement, make and grip the opposite side axial end that card 4 is gripped on gripping shelves 3, left side axial end as shown in Figure 4, " relatively roller overlaps 2 left side to yarn traverse a, thereby makes the one-sided yarn traverse of bearing become two by one, and be doubled service life at this moment.
The utility model grips shelves lip-deep annular knurl reticulate pattern of 3 cylindrical journal or cannelure line, can increase the frictional force that grips card 4 and grip 3 of shelves, make bearing 1 when work, can not produce axial float, thereby have axial stability preferably with long gripping shelves 3.
Claims (2)
