Abstract
The invention relates to a top-roller leather roller bearing with an axial displacement holding stop, which is widely applied to draft nips of various spinning frames, in particular to draft nips of compact spinning frames, and belongs to the field of manufacture of textile special parts. A holding clip on a rocker bracket can be used for axially holding in an interval on a spindle; a plurality of holding grooves are formed on the spindle; clearance fit is formed between the width of the holding grooves and the single-side thickness of the holding clip on the rocker bracket; and the holding clip on the rocker bracket can be clamped into at least two of the plurality of holding grooves. The top-roller leather roller bearing has the advantages of improving the rubber roller utilization rate, holding stably, having a simple structure, and saving cost, and the like.
Description
Technical field
But the present invention relates to a kind of top-roller leather roller bearing of axial displacement holding stop, be widely used in being particularly useful for closely spinning the drawing-off jaw of fine spining machine in the drawing-off jaw of various fine spining machines, belong to the special part of weaving and make the field.
Background technology
The domestic and international at present top-roller leather roller bearing of producing, its holding stop length all is slightly larger than the about 0.3mm of width of the gripping card of fine spining machine reel cage, thereby when the gripping card of reel cage snapped in the holding stop of bearing, the axial location of top-roller leather roller bearing promptly was fixed on the reel cage, can't realize axial displacement.Depressing reel cage is pressed on the roller shaft rubber roll on the top-roller leather roller bearing and the drawing-off jaw that forms spinning.Owing in the drafting process of spinning, exist the amplitude of oscillation traverse of yarn, and this amplitude of oscillation traverse generally is set on 6～8mm, and effective active length of whole rubber roll reaches 24mm, that is to say the actual operating position that has only utilized 6～8mm length on effective active length of rubber roll 24mm, the utilization rate of its rubber roll has only 30%.Compact spinning technique constantly promotes the use in China in recent years, and closely the spinning amplitude of oscillation traverse of spinning process generally only is set in about 3mm, and as seen the utilization rate of its rubber roll is lower.Therefore textile industry urgently wishes to have the top-roller leather roller bearing appearance that a kind of utilization rate that can make rubber roll significantly rises.
Summary of the invention
The deficiency that on the too low problem of rubber roll utilization rate, exists at present top-roller leather roller bearing, but the present invention proposes the top-roller leather roller bearing of kind of axial displacement holding stop.
The present invention implements by the following technical solutions, and gripping card, gripping groove, rubber roll constitute down by gripping card, reel cage making leaf spring, reel cage on shell, mandrel, the reel cage for it.It is characterized in that described mandrel is provided with many gripping grooves; It is matched in clearance that described gripping groove width and reel cage grip between the monolateral thickness that blocks; Have at least two grooves to be snapped in described many gripping grooves by the gripping card of reel cage.
The present invention have improve the rubber roll utilization rate, grip firm, simple in structure, save advantage such as cost.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
In accompanying drawing 1: grip on 1 shell, 2 mandrels, 3 reel cages and grip card, 6 gripping grooves, 7 rubber rolls under card, 4 reel cage making leaf springs, 5 reel cages.
The specific embodiment
As shown in Figure 1,, grip card 3, reel cage on the width of gripping groove 6 and the reel cage and grip down between the monolateral thickness of card 5 and cooperate at six gripping grooves 6 of the turning in the middle part of mandrel 2 with shaped profile turning cutter for the simple crack of basic shaft system.The bottom land footpath basic size of gripping groove 6 is ￠ 9.5mm.Shell 1 usefulness steel ball and retainer are contained on the mandrel 2, on the external cylindrical surface of shell 1, are inserted in rubber roll 7.Closely spinning on the fine spining machine, gripping down and snap in shown in the accompanying drawing 1 of the present invention in the gripping groove 6 position under card 5 the spring power effect and when working, the amplitude of oscillation traverse of yarn is in a zone position of accompanying drawing 1 at reel cage making leaf spring 4 when gripping card 3 and reel cage on the reel cage.Active section after the time (about 3～4 months) unload lower bearing, make on the reel cage to grip card 3 and reel cage and grip card 5 down and snap in position and work in the gripping groove 6 shown in the accompanying drawing 2 of the present invention, this moment, the amplitude of oscillation traverse of yarn was in a ' zone position of accompanying drawing 2.Active section after the time (about 3～4 months) unload lower bearing, make on the reel cage to grip card 3 and reel cage and grip card 5 down and snap in position and work in the gripping groove 6 shown in the accompanying drawing 3 of the present invention, this moment, the amplitude of oscillation traverse of yarn was in a " zone position of accompanying drawing 2.Temper in the cycle at the individual of rubber roll 7 external cylindrical surfaces like this, realized three times utilization rate, and formed three the traverse zones of three rubber roll 7 displacements are not overlapping.Split at common ring and to spin on the fine spining machine, the spinning traverse of spinning generally is set at 6～8mm because ring splits, therefore grip card 5 down when snapping in shown in accompanying drawing 2 of the present invention and the accompanying drawing 3 in the gripping groove 6 respectively with gripping card 3 and reel cage on the reel cage, the twice utilization rate of rubber roll 7 can be realized in two traverse zones that can obtain rubber roll 7, and formed two the traverse zones of twice rubber roll 7 displacement are not overlapping.
Claims (3)
- But 1. the top-roller leather roller bearing of an axial displacement holding stop, it by grip on shell, mandrel, the reel cage card, reel cage making leaf spring, reel cage down gripping card, gripping groove, rubber roll constitute, it is characterized in that described mandrel is provided with many gripping grooves.
- 2. but the top-roller leather roller bearing of a kind of axial displacement holding stop according to claim 1 is characterized in that it is matched in clearance that described gripping groove width and reel cage grip between the monolateral thickness that blocks.
- 3. but the top-roller leather roller bearing of a kind of axial displacement holding stop according to claim 1 and 2 is characterized in that having at least in described many gripping grooves two grooves to be snapped in by the gripping card of reel cage.
