Abstract

The utility model discloses a one-step forming synchronous belt, wherein a belt body is annular. The one-step forming synchronous belt is structurally characterized by comprising a belt back, belt teeth and belt tooth wrapping cloth wrapped on the surfaces of the belt teeth from inside to outside, a core rope is laid along the circumference direction in the belt body; and the inner wall of the belt body is provided with uniform convex-concave grid patterns. According to the synchronous belt and a manufacturing method thereof, the process is simple, the raw material consumption is less, the cost is low, furthermore the manufactured products are better in abrasion resistance, the service life is longer, noise is reduced effectively, and problems such as scrap falling and the like are avoided.

Description

A kind of once-through is with synchronously

Technical field

The utility model relates to a kind of synchronous band, and especially a kind of once-through is with synchronously.

Background technique

Synchronously band is to be strength layer with wire rope or glass fibre, covers the endless belt with polyurethane or neoprene outward, band interior week process dentation, itself and profile of tooth belt wheel are meshed.During band work synchronously, velocity ratio is accurate, and is little to the axle active force, compact structure, and oil resistant, wear-resisting property and aging quality resistance are all higher, and its serviceability temperature is at-20 ℃-80 ℃, and for requiring synchronous transmission also to can be used for the low speed transmission.

Just owing to the above characteristics of being with synchronously, its transmission product is widely used in the various types of mechanical transmission of every profession and trade such as weaving, lathe, tobacco, communication cable, light industry, chemical industry, metallurgy, instrument, food, mine, oil, automobile.But current synchronous band production technology commonly used is complicated, and it is more to expend raw material, so cost is also higher; The synchronous band transmission capacity of its production is less, has certain noise during use, and is easy to generate bits; Phenomenons such as accelerated wear test, can not be fit to environmental requirement high applications.

The model utility content

The utility model provides a kind of once-through to be with synchronously, the noise in the time of can solving synchronous tape running with fall the bits problem, this manufacturing approach craft is simple, it is few to expend raw material, cost is low, and the product wear-resisting property is better, longer service life.

For realizing above-mentioned purpose, adopt following technological scheme:

A kind of once-through is with synchronously, and belt body is an annular, it is characterized in that, its structure is followed successively by the band back of the body, band tooth from inside to outside, is wrapped in the band tooth infantees of band tooth surface, and belt body circumferential direction inside direction is equipped with the core rope, and the belt body inwall has concavo-convex uniform grid decorative pattern.

The said synchronous band structure of the utility model is simple, and it is few to expend raw material, and cost is low, and the product wear-resisting property of producing is better, and longer service life effectively reduces noise, has avoided problems such as bits.

Description of drawings

According to embodiment and accompanying drawing the utility model is done further explain below.

Fig. 1 is the cross-sectional view of the utility model.

Among the figure:

1, the band back of the body; 2, core rope; 3, band tooth; 4, band tooth infantees.

Embodiment

As shown in Figure 1; Provided a specific embodiment of the utility model, among the figure, the belt body structure is followed successively by the band back of the body 1, band tooth 3 from inside to outside, is wrapped in the band tooth infantees 4 of band tooth surface; Belt body circumferential direction inside direction is equipped with core rope 2, and the belt body inwall has concavo-convex uniform grid decorative pattern.

The production method of band comprises the steps: synchronously

A, select suitable seamless steel pipe to carry out the gum cover Mould Machining according to the size of mould;

B, rubber composition is carried out mixing, mixing sizing material is rolled into required thickness;

C, film is attached in order on the mould of making made-up belt, on forming mould, is inserted in the cloth cover, then outside the core rope that keeps the constant state of tension force will pass through adhesive treatment down is wrapped in band tooth infantees;

D, made-up belt is carried out vulcanizing treatment;

E, by product width requirement cutting made-up belt.

In the utility model; Belt body can be selected following prescription (by weight) for use with the used rubber composition of the band back of the body: 100 parts of neoprenes, 50 parts of semi-reinforcing carbon blacks, 1.5 parts of stearic acid; 2 parts of age resister, 2 parts of processing aids, 5 parts of magnesia, 5.5 portions of Active agents; 1.5 part dispersing agent, 4 parts of zine oxide, 1 part of promoter.

After selecting traditional mixing facilities mixing of rubber for use, sizing material is rolled into the film that thickness is 0.6mm, film is attached on the made-up belt of forming, the first layer film is first can not to surpass 5mm with second layer film cabrage is folded, carries out severing with ruler and cut-off knife.After film is laid and accomplished, when laying trans-printing paper, must keep straight, printing paper lettering face is pressed close to the band tube.In the spray of the gum cover inwall made behind a small amount of and uniform releasing agent, gum cover is placed on carries out preheating in the steam vulcanization (cure) jar, after accomplishing, preheating is enclosed within the made-up belt outside of forming, and made-up belt outer wall and gum cover inwall gap are about 5mm, large flat bread on the pad.Under certain vapor pressure, time, in sulfurizing pot, vulcanize then.In the HTHP sulfidation, these fluidised rubber form rubber layer and form the band tooth with the rubber of being with the tooth infantees to be pressed into together in the teeth groove, simultaneously because the grid decorative pattern of gum cover inwall is with back of the body surface also to be pressed into concavo-convex uniform grid decorative pattern.Behind sulfidization molding, the cylindrical shape belt body is taken out from sulfurizing pot, it is carried out the demoulding, then the band tube is cut by certain width, can obtain many bands synchronously simultaneously.

The said manufacturing approach craft of the utility model is simple, and it is few to expend raw material, and cost is low, and the band tooth infantees of band is handled through soaking paste synchronously, not only makes band tooth infantees have adhesiveness preferably, also has wear resistance preferably.Through making to gum cover, make belt band back of the body surface concavo-convex uniform grid decorative pattern occur, not only reduce the generation of band bubble, pore phenomenon synchronously; And reduce that band synchronously produces in the running consider to be worth doing phenomenon, through moulding, make the sizing material cost of making the band tube reduce about 30% to made-up belt; Through sulfuration to made-up belt; Once decide profile of tooth and the concavo-convex uniform grid decorative pattern of the band back of the body, eliminate the rubber dust polluting environment that produces because of grinding, improved the work and the production environment of machine; Safety and environmental protection more, and effectively prolonged working life of machine.
