Abstract

The utility model belongs to Idler Technology field, relates to nylon composite roll specifically, and its technical characteristics is: comprise metal inner pipe and cotton garment, between described metal inner pipe and cotton garment, be provided with cushion rubber layer.As further improvement of the utility model, be provided with helical groove at metal inner pipe lateral surface or be fixed with at described metal inner pipe lateral surface the helical form fin that cross section is " C " type.When temperature generation acute variation, can there is compression or extensional in the cushion rubber layer between metal inner pipe and cotton garment, avoid metal inner pipe and cotton garment comes off or cotton garment is split up, and extends the service life of carrying roller.

Description

Nylon composite roll

Technical field

The utility model belongs to nylon roller technical field, particularly relates to nylon composite roll.

Background technology

In mining or metal smelt process, short distance mass transport adopts tape transport mostly.Current carrying roller mainly contains following several: one, metallic roll, and this metallic roll intensity is large, but corrosion-resistant and wear no resistance, and the place for poor working environment does not generally adopt; Its two, nylon carrying roller, has nylon jacket in metal shaft arranged outside, and this nylon jacket thickness is large, and weight is large, and cost is high; They are three years old, at nylon composite roll, nylon jacket is wrapped up outside metal tube, this nylon composite roll is lightweight, wearability and good corrosion resistance, but in production process or use procedure, variations in temperature is large, especially in process of production, because metal tube is different from the coefficient of thermal expansion and contraction of nylon jacket, cause nylon jacket to be split up, affect nylon composite roll service life.

Utility model content

The technical problem of solution of the present utility model be just to provide a kind of lightweight, intensity is large, corrosion-resistant and anti-wear performance strong, the nylon composite roll of long service life.

The technical solution adopted in the utility model is: comprise metal inner pipe and cotton garment, between described metal inner pipe and cotton garment, be provided with cushion rubber layer.

Its additional technical feature is:

Described metal inner pipe lateral surface is provided with helical groove;

Helical form fin is fixed with at described metal inner pipe lateral surface;

The cross section of described helical form fin is " C " type.

Nylon composite roll provided by the utility model compared with prior art, have the following advantages: one, owing to comprising metal inner pipe and cotton garment, cushion rubber layer is provided with between described metal inner pipe and cotton garment, like this, when temperature generation acute variation, can there is compression or extensional in the cushion rubber layer between metal inner pipe and cotton garment, avoid metal inner pipe and cotton garment comes off or cotton garment is split up, extend the service life of carrying roller; Its two, owing to being provided with helical groove at described metal inner pipe lateral surface or being fixed with helical form fin at described metal inner pipe lateral surface, cushion rubber layer and metal inner pipe can be avoided to come off and slide axially, and cotton garment is more firm; Its three, the cross section due to described helical form fin is " C " type, not only avoids sliding axially of cushion rubber layer and metal inner pipe, and fin has certain elasticity in the radial direction at metal inner pipe, avoids cotton garment and is split up.

Fig. 2 is the axial enlarged cross-sectional view of the nylon composite roll with helical groove;

Fig. 3 is the axial enlarged cross-sectional view of the nylon composite roll with helical form fin.

Detailed description of the invention

Below in conjunction with accompanying drawing, the structure of the utility model nylon composite roll and use principle are described in further details.

As shown in Figure 1, the utility model nylon composite roll, comprises metal inner pipe 1 and cotton garment 2, is provided with cushion rubber layer 3 between metal inner pipe 1 and cotton garment 2.Like this, when temperature generation acute variation, can there is compression or extensional in the cushion rubber layer 3 between metal inner pipe 1 and cotton garment 2, avoid metal inner pipe 1 and cotton garment 2 comes off or cotton garment 2 is split up, and extends the service life of carrying roller.

As shown in Figure 2, the lateral surface of metal inner pipe 1 is provided with helical groove 4, or as shown in Figure 3, is fixed with helical form fin 5 at metal inner pipe 1 lateral surface, cushion rubber layer and metal inner pipe can be avoided to come off and slide axially, and cotton garment is more firm.

The cross section of helical form fin 5 is " C " type, not only avoids sliding axially of cushion rubber layer 3 and metal inner pipe 2, and helical form fin 5 has certain elasticity in the radial direction at metal inner pipe 1, avoids cotton garment 2 and is split up.

Protection domain of the present utility model is not only confined to above-described embodiment, as long as structure is identical with the structure of the utility model nylon composite roll, just drops on the scope of the utility model protection.

Claims

1. nylon composite roll, comprise metal inner pipe and cotton garment, between described metal inner pipe and cotton garment, be provided with cushion rubber layer, it is characterized in that: be provided with helical groove at described metal inner pipe lateral surface or be fixed with helical form fin at described metal inner pipe lateral surface.

2. nylon composite roll according to claim 1, is characterized in that: the cross section of described helical form fin is " C " type.
