Abstract
The utility model relates to an improved structure of a free wire wheel, which comprises a wire coil, a rotating shaft and a brake mechanism. An axial through hole is formed on the wire coil; a first containing dish and a second containing dish which are formed at the ports of the through hole, with the diameters being larger than that of the corresponding ports respectively, are formed on two end surfaces of the wire coil; a first bearing and a second bearing which can bear radial force are respectively installed in the first containing dish and the second containing dish; the rotating shaft is positioned in the through hole and supported through the first bearing and the second bearing; a third bearing which can bear radial force is also installed on the rotating shaft on the outer side of the first bearing; the brake mechanism is positioned on the outer side of the second bearing; a spring is sleeved on the rotating shaft between the brake mechanism and the second bearing; and simultaneously a sleeve with two ends being propped against inner rings of the first bearing and the second bearing is also sleeved on the rotating shaft between the first bearing and the second bearing. An axial force can be transmitted to the third bearing through the sleeve, so as to ensure that the axial force on the first bearing and the axial force on the second bearing are balanced, the normal operation of the wire coil is guaranteed, and the service life of the wire wheel can also be prolonged.
Description
Technical field
The utility model relates to a kind of fishing line reel, specifically refers to the improvement structure of the free line wheel in a kind of fishing line reel.
Background technology
Free line wheel in the fishing line reel is to be used for twining fishing line; And has the function that to carry out unwrapping wire, take-up and brake as required; It comprises drum, rotating shaft and braking mechanism; As shown in Figure 3, have axial pass-through holes on the drum, on the both ends of the surface of drum, have first housing recess and second housing recess that form in the through hole port respectively; The diameter of this first housing recess, second housing recess is greater than the corresponding port of through hole; In first, second housing recess, be separately installed with first, second bearing of ability bearing radial force, rotating shaft is arranged in through hole and is supported by first, second bearing, in the rotating shaft in the clutch shaft bearing outside, the 3rd bearing that can bear axial force is installed also; Braking mechanism is positioned at second bearing outside, in the rotating shaft between the braking mechanism and second bearing, also is with to make second bearing and drum have the spring to clutch shaft bearing side shifting trend all the time.During outlet, drum freely rotates around the shaft through first, second bearing and realizes unwrapping wire.After when a fish snapped at the bait; Need carry out brake operation to drum, at this moment, drum is under the effect of braking mechanism;, brake to the braking mechanism side shifting along rotating shaft through the frictional force between brake block in the braking mechanism (being fixed on drum one end face) and the brake disc.When needs are removed brake weight, then under the effect of back-moving spring, drum is moved axially reset.
But in the above-mentioned line wheel; Because inner ring and the spring of second bearing offset, so in brake process repeatedly, make second bearing can receive an axial shearing force; This shearing force can influence the normal retractable line flexibly of drum, also can influence the service life of second bearing simultaneously.
The utility model content
The utility model technical problem to be solved is the present situation to prior art, provides a kind of and can guarantee that drum freely rotates the improvement structure of the free line wheel that also can increase the service life.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the improvement structure of this free line wheel comprises drum, rotating shaft and braking mechanism; Have axial pass-through holes on the said drum; On the both ends of the surface of said drum, have first housing recess and second housing recess that form in the through hole port respectively; And the diameter of this first housing recess, second housing recess is greater than the corresponding port of through hole; In said first, second housing recess, be separately installed with first, second bearing of ability bearing radial force; Said rotating shaft is arranged in said through hole and is supported by first, second bearing; In the rotating shaft in the said clutch shaft bearing outside, the 3rd bearing that can bear axial force is installed also, said braking mechanism is positioned at said second bearing outside, and in the rotating shaft between the said braking mechanism and second bearing, also is with and makes second bearing and drum have the spring to clutch shaft bearing side shifting trend all the time; It is characterized in that: also be with a sleeve pipe in the rotating shaft between the said clutch shaft bearing and second bearing, the two ends of this sleeve pipe offset with the inner ring of clutch shaft bearing, second bearing respectively.
Preferably, has the gap between described sleeve pipe and the rotating shaft, to reduce wearing and tearing between the two.
Compared with prior art; Because the sleeve pipe in the utility model is butted between first, second bearing; Therefore be passed to the 3rd bearing through second, one bearing successively through the axial force of sleeve pipe can be with brake the time; Axial force on first and second bearing is offset, guaranteed the drum operate as normal, and the service life of ability extended line wheel.

Fig. 2 is the cutaway view of Fig. 1;
Fig. 3 is the cutaway view of prior art center line wheel.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2; The improvement structure of this free line wheel comprises drum 1, rotating shaft 2 and braking mechanism 3; Wherein have axial pass-through holes 11 on the drum; Have first housing recess and second housing recess that form in the through hole port on the both ends of the surface of drum respectively, and the diameter of this first housing recess, second housing recess is greater than the corresponding port of through hole, in first, second housing recess, be separately installed with can bearing radial force clutch shaft bearing 4, second bearing 5.
Said rotating shaft 2 is arranged in the through hole of above-mentioned drum 1, and is supported by first, second bearing, in the rotating shaft in the clutch shaft bearing outside, the 3rd bearing 6 that can bear axial force is installed.Above-mentioned braking mechanism 3 is a conventional structure; Be positioned at second bearing, 5 outsides; It comprises brake block 31 and the brake disc 32 that is oppositely arranged with brake block; Brake block 31 is fixed on the end face that is equipped with second bearing in the drum 1; In the rotating shaft between the braking mechanism and second bearing 5, also be with and make second bearing and drum have the spring 7 to clutch shaft bearing 4 side shifting trend all the time, in the rotating shaft between the clutch shaft bearing and second bearing, also be with a sleeve pipe 8 simultaneously, the two ends of this sleeve pipe offset with the inner ring of clutch shaft bearing 4, second bearing 5 respectively.
In order to reduce the frictional force between sleeve pipe 8 and the rotating shaft 2, has the gap between sleeve pipe and the rotating shaft.
Obviously, behind the employing said structure, can make first and second bearing no longer bear axial shearing force, thereby can guarantee the flexible rotation of drum, and can prolong the service life of bearing and drum.
