Description

A kind of winch drum device

Technical field

The utility model relates to field of mechanical technique more particularly to a kind of winch drum devices.

Background technique

Winch mainly applies to the material lifting of building, hydraulic engineering, forestry, mine, harbour etc. or puts down drag, and is to use roller Winding wire ropes or chain are to promote or lead the light and small heavy-duty hoisting equipment of weight.Roller is used to traction, and stress is huge.It is existing Roller substantially there are two types of, be divided into monoblock type and spliced, monoblock type manufacture is complicated, and higher cost needs integral replacing after damage, Cause huge waste；And though spliced roller is replaced convenient, load-bearing is more much smaller than monoblock type, when load-bearing is larger, splicing Position is easy to damage, causes the trouble of subsequent replacement.

Summary of the invention

In order to overcome the drawbacks of the prior art, the utility model provides a kind of simple monoblock type roller, is simple to manufacture, adopts With general steel plate, cost is relatively low, and load-bearing is higher.

To achieve the goals above, the utility model the following technical schemes are provided:

A kind of winch drum device is used for traction, from left to right includes gear, circle cylinder and drum shaft；The tooth Wheel and circle cylinder cover on drum shaft jointly；First bearing and second are separately installed at the gap at the drum shaft and circle cylinder both ends Bearing, the first bearing and second bearing cover on the outside of drum shaft；The gear is fixedly connected by bolt with circle cylinder.

Further, it is equipped with oil sealing between the gear and circle cylinder, the oil sealing is placed on drum shaft.

Further, the bolt is being equipped with washer with circle cylinder junction.

Further, the drum shaft both ends are equipped with screw thread, and are furnished with corresponding nut.

Further, the cylinder surface among the circle cylinder is smooth, and the cylinder surface is wound with wirerope.

Beneficial effect brought by the utility model is: using the iron work of ordinary steel, cost can be reduced, using monoblock type knot Structure is hardly damaged, and load-bearing is higher, and cylinder surface is smooth, easy cleaning, without often replacement.

Detailed description of the invention

Fig. 1 is the utility model structure diagram

Fig. 2 is the structural schematic diagram of gear.

Figure label are as follows:

1, nut；2, first bearing；3, gear；4, oil sealing；5, cylinder is enclosed；501, roller；502, wirerope；6, drum shaft； 7, second bearing；8, washer；9, bolt.

Specific embodiment

The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear Define.

As shown in Figure 1, a kind of winch drum device, is used for traction, it from left to right include gear 3, circle cylinder 5 and rolling Cylinder axis 6；The gear 3 and circle cylinder 5 are covered jointly on drum shaft 6；Pacify respectively at the drum shaft 6 and the gap at circle 5 both ends of cylinder Equipped with first bearing 2 and second bearing 7,7 sets of the first bearing 2 and second bearing are in 6 outside of drum shaft；The gear 3 is logical Bolt 9 is crossed to be fixedly connected with circle cylinder 5.

Further, it is equipped with oil sealing 4 between the gear 3 and circle cylinder 5, the oil sealing 4 is placed on drum shaft 6.

Further, the bolt 9 is being equipped with washer 8 with circle 5 junction of cylinder.

Further, 6 both ends of drum shaft are equipped with screw thread, and are furnished with corresponding nut 1.

Further, 501 surface of roller among the circle cylinder 5 is smooth, and 501 surface wrap of roller has wirerope 502。

The present invention will be further described with working principle with reference to the accompanying drawing.

The drum shaft 6 is installed on winch, and fixation is tightened by nut 1 in both ends, it is made not rotate；In drum shaft Gear 3 and circle cylinder 5 are cased on 6, middle gear 3 and circle cylinder 5 are fixed by bolt 9, and drum shaft 6 and circle cylinder 5 pass through bearing 2,7 Connect, when rotating, circle cylinder 5 rotates gear 3 simultaneously, and the wirerope 502 on roller 501 starts to elongate or shorten, bearing Corresponding operating, at this point, drum shaft 6 does not rotate.

Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to In this, anyone skilled in the art, can be without creative labor in the technical scope disclosed by the utility model The dynamic change or replacement expected, should be covered within the scope of the utility model.Therefore, the protection model of the utility model Enclosing be determined by the scope of protection defined in the claims.
