Description
Technical field
The utility model relates to a kind of chain-driven automatic takeup, and particularly a kind of chain-driven automatic takeup that is applied on the water tank type wire drawing machine belongs to mechanical field.
Background technique
In the water tank drawbench equipment of drawing metal wire rod, use the part of sprocket wheel now mostly as transmission.Because of low price, chain-driven has just replaced a part of gear transmission.In the work of water tank drawbench, the transmission case place has bigger noise, causes the working environment noise pollution, is unfavorable for the healthy of wire drawer.In addition, cause the sprocket wheel wearing and tearing severe in the chain-driven, transmission efficiency is poor, and the sprocket wheel life-span is low.In drawing process, influence the problem that metal wire rod second flow amount equates, and the fracture of wire phenomenon occurred.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of reasonable in design, can realize auto-tensioning, reduce noise, effectively reduce the chain-driven automatic takeup of fracture of wire phenomenon.
It is this chain-driven automatic takeup that the utility model solves the problems of the technologies described above the technological scheme that is adopted, its structural feature is: by supporting base, the supporting base bearing pin, fork, Oscillating lever bearing, axostylus axostyle, the axostylus axostyle bearing pin, spring, spring housing, duplex chain wheel, sprocket shaft bearing, the sprocket wheel bearing pin, the sprocket wheel cover is formed, wherein, supporting base is fixed on the water tank drawbench casing, fork links to each other with supporting base by the supporting base bearing pin, Oscillating lever bearing is arranged in the fork, fork is movably connected by axostylus axostyle bearing pin and axostylus axostyle, axostylus axostyle is provided with spring, be set with spring housing on the spring, fork also is connected with an end of sprocket wheel bearing pin, the sprocket wheel bearing pin is arranged in the duplex chain wheel, between sprocket wheel bearing pin and duplex chain wheel, be provided with two sprocket shaft bearings and two circlip for holes, circlip for hole is arranged on outside the sprocket shaft bearing, and two sprocket shaft bearings are separated by the sprocket wheel cover.
The utility model is compared with prior art and is had the following advantages and effect: owing on sprocket wheel, be provided with automatic takeup, makes to make the sprocket wheel wearing and tearing little in the chain-driven, and the transmission efficiency height, the sprocket wheel life-span is greatly improved.Drawing process is also more reliable and more stable, and noise significantly reduces.
Description of drawings
Fig. 1 is installed in overall structure schematic representation on the water tank drawbench for the utility model;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is an External view schematic representation of the present utility model.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail, following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment 1: as shown in Figures 1 to 3, present embodiment is made up of duplex chain wheel 9, circlip for hole 15, sprocket shaft bearing 16, sprocket wheel bearing pin 17, sprocket wheel cover 18, spring 19, spring housing 20, M20 hexagon nut 21, axostylus axostyle 22, M16 hexagon nut 23, M12 hexagon nut 24, axostylus axostyle bearing pin 25, supporting base bearing pin 26, spring washer 27, supporting base screw 28, supporting base 29, Oscillating lever bearing 30, fork 31.
During wire drawing, water tank drawbench 1 drives 6 runnings of main frame belt wheel by motor 13 and electrical machine belt pulley 14 by 6 belts 12.Belt wheel 6 drives main shaft 7, driving gear 5, driven gear 2, axle 4, drive sprocket 3, drives by movable sprocket 11 through chain-driven.Duplex chain wheel 9 is arranged on the double strand chain 8.Duplex chain wheel 9 adopts thin oil lubricant as automatic takeup in this transmission process.
9 grades of M20 hexagon nuts 21 of do as one likes energy are down tightened and are pressed down spring housing 20, make spring 19 compressions of 65Mn steel, 45# steel axostylus axostyle 22 and Q235 steel fork 31 are with 45# steel axostylus axostyle bearing pin 25, two ends are locked with 9 grades of M12 hexagon nuts 24 of performance and are not locked, axostylus axostyle bearing pin 25 is active sections, on fork 31, swing up and down automatically, thereby fork 31 reaches the auto-tensioning effect according to double strand chain 8 tensioning situations.Fork 31 is housed on the supporting base bearing pin 26, for making fork 31 swings, between supporting base bearing pin 26 and the fork 31 Oscillating lever bearing 30 is housed, supporting base bearing pin 26 and 23 lockings of 9 grades of M16 hexagon nuts of Q235 steel supporting base 29 usefulness performances, the spring washer 27 of 2 performances of supporting base 29 usefulness, 8.8 grades of M12 supporting bases screw 28 and 2 65Mn are connected with the water tank drawbench casing to be supported.Centre of duplex chain wheel 9 and 2 sprocket shaft bearing 16 one side is separated by with sprocket wheel cover 18 and is assemblied on the sprocket wheel bearing pin 17, at duplex chain wheel 9 two ends circlip for hole 15 is housed and blocks sprocket shaft bearing 16, sprocket wheel bearing pin 17 adopts 9 grades of M16 hexagon nut lockings of performance with fork 31, and duplex chain wheel 9 rotates on double strand chain 8 under the auto-tensioning state in chain-driven.Adopt automatic takeup of the present utility model to improve chaindriven efficient, reduced chaindriven noise.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
