A plurality of sets of shaft sleeve type oppositely-opened wheels (2) are fixedly installed on the outer surface of a metal mandrel (1) side by side, each set of oppositely-opened wheel is composed of two semicircular oppositely-opened wheel units, and each oppositely-opened wheel unit is connected with the metal mandrel (1) through a key; the semicircular oppositely-opened wheel units of each set of oppositely-opened wheel are mutually connected; the outer wall face of each oppositely-opened wheel (2) is provided with a chain gear (2-1) used for hanging a net belt chain. The metal mandrel and the oppositely-opened wheels are of a split structure and are mutually and fixedly assembled as a whole, so that assembling and disassembling are convenient, only the oppositely-opened wheels at a certain section need to be replaced in the process of repairing, the driving shaft does not need to be integrally replaced, and therefore the maintaining cost of an enterprise using the split type net belt driving shaft is greatly reduced.

Description

The split type guipure imput shaft of sterilization machine

Technical field

The utility model relates to a kind of axle drive shaft of load-transfer device, is specifically related to a kind of guipure imput shaft of sterilization machine.

background technology

The existing guipure imput shaft of sterilization machine is integral type metal, and its surface is sprocket gear for coordinating with guipure with several.Because the applied environment of sterilization machine is high temperature, alkaline environment, sprocket gear position is easy to be corroded by chemical and affects transmission effect and even causes transmission failure, in this case can only integral replacing imput shaft, on the one hand due to the higher maintenance cost that increases enterprise of imput shaft cost, on the other hand, frequent replacing, maintenance have affected production efficiency.

Utility model content

Technical problem to be solved in the utility model is, provide a kind of sterilization machine split type guipure imput shaft, by adopting the better split wheel of corrosion stability and metal core axle to fix, form split type guipure imput shaft, there is longer service life, and while safeguarding, only need to change split wheel, to overcome the defect of existing guipure imput shaft.

In order to solve this technical matters, the utility model by the following technical solutions:

The split type guipure imput shaft of a kind of sterilization machine, it is characterized in that: comprise metal core axle, metal core axle outside face is installed with the split wheel of some groups of axle sleeve forms side by side, and each group split wheel is comprised of two semicircle split wheel unit, between split wheel unit and metal core axle, by key, is connected; Between two split wheel unit of every group of split wheel, be connected to each other; In the outside wall surface of split wheel, be provided with for articulating the sprocket gear of guipure chain.

Preferably, split wheel used is nylon split wheel.

Preferably, the connection mode between two of every group of split wheel split wheel unit is: along split wheel, be circumferentially provided with evenly distributedly at least two bolts that two split wheel unit of every group of split wheel are linked together.

Preferably, one end of metal core axle is provided with one group of split wheel with two-fold face section, and other group split wheels are the split wheel with single folding face section; The described split wheel with two-fold face section, its outside wall surface has two sections and is respectively in the folding face section that sprocket gear both sides and cross section are equilateral polygon; The described split wheel with single folding face section, its outside wall surface has the folding face section that one section of cross section is equilateral polygon.

Good effect of the present utility model is:

The first, metal core axle and split wheel are Split type structure, by interfixing, fit together, and are convenient to dismounting, only need to change certain section of split wheel, and not need integral replacing imput shaft, thereby significantly reduced the maintenance cost of using enterprise while safeguarding.

The second, split wheel adopts nylon material, has good mechanical property, decay resistance, self lubricity and lower friction coefficient, and has light weight, is easy to the feature of processing, has guaranteed that guipure imput shaft has longer service life.

Three, easy making process, low cost of manufacture, operation and maintenance is more convenient.

Fig. 4 is structure, the shape schematic diagram with the split wheel of two-fold face section.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further described.

As Fig. 1, shown in 2, embodiment of the present utility model comprises the metal core axle 1 of tubulose, the surface of metal core axle 1 is with the trend mandrel keyway 1-1 consistent with metal core axle 1 line of centers, at metal core axle 1 outside face, be fixed with side by side the split wheel 2 of some groups of axle sleeve forms, each group split wheel is two semicircle split wheel unit, on the internal face of each split wheel unit, offer respectively the split wheel keyway 2-2 that trend is consistent with metal core axle 1 line of centers, between split wheel unit and metal core axle 1, by flat key 3, be connected to each other, with relatively rotating between restriction split wheel 2 and metal core axle 1.Between two split wheel unit of every group of split wheel, be connected to each other.Between two split wheel unit of every group of split wheel, preferred connection mode is: along split wheel 2, be circumferentially provided with evenly distributedly four bolts 4 that two split wheel unit of every group of split wheel are linked together.

In the outside wall surface of split wheel 2, be provided with for articulating the sprocket gear 2-1 of guipure chain.

Described split wheel 2 comprises two kinds of forms, and the first is for to have the split wheel of single folding face section as shown in Figure 3, and its outside wall surface has the folding face section 2-3 that one section of cross section is equilateral polygon (such as positive pentadecagon).The second is for having as shown in Figure 4 the split wheel of two-fold face section, and its outside wall surface has two sections and is respectively in sprocket gear 2-1 both sides and cross section is the folding face section 2-3 of equilateral polygon (such as positive pentadecagon).

Folding face during work on this folding face section 2-3 is for coordinating with guipure carrier bar, and this folding face section 2-3 circumferential position is as the running space of guipure carrier bar.

As Fig. 1, one group of split wheel with two-fold face section is installed in the one end on same metal core axle 1, and other group split wheels are the split wheel with single folding face section.If the split wheel with two-fold face section is positioned at the left end of metal core axle 1, the folding face section 2-3 of other split wheel is all positioned at the right-hand member of place split wheel, with the split wheel outer end of guaranteeing two ends, imput shaft left and right all with folding face section 2-3, to adapt to the position of guipure carrier bar.

In use, when finding that certain group split wheel damages, the bolt unclamping on this group split wheel is changed this group split wheel, and need not integral replacing imput shaft.

Metal core axle 1 material therefor is No. 45 steel preferably.

Split wheel 2 used is preferably nylon split wheel.
