Abstract

The utility model belongs to a driving belt in the mechanical transmission. A roller chain (3) packed by an outer packing layer (1) and a filling layer (2) takes place of a reinforcing layer in an ordinary driving belt. The outer edge of the driving belt of a pin axle (5) position on the roller chain (3) is provided with an incision (4), and the lower end of the incision (4) is provided with a circular small hole (6).

Description

A kind of driving belt

The utility model belongs to the driving belt in the mechanical transmission, especially relates to the existing frictional driving belt of being made up of strength layer surrounding layer and filling bed.

Use the mode of band transmission to come transferring power very general now in the machinery,, but be with transmission also to exist some shortcomings simultaneously because of the band drive mechanism is simple, with low cost.Band transmission coefficient of elongation in transmission is bigger, therefore the power that transmits is less, many belts of many employings solve in bigger power transmission, and driving belt in use damages the overwhelming majority and breaks in transmission, rather than be worn bad and change, in the band transmission, all need installation tensioner simultaneously, guarantee with the required frictional force of transmission.

It is little that the purpose of this utility model provides a kind of coefficient of dilatation, long service life, the driving belt that is difficult for skidding.

For solving above-mentioned task, the technical solution that the utility model adopts is: the strength layer in the common driving belt is used by surrounding layer and packed layer be wrapped in interior chain replacement.

Because in the above-mentioned solution, the utility model has adopted chain to replace strength layer, has obtained following technique effect:

1, because this novel employing replaces chain the method for strength layer in the driving belt, therefore this nothing of tape base elongation in use is so by the adjusting to pretension, can be used for transmitting the occasion of different capacity, strengthened the ability of driving belt transmitted power, and also improve working life greatly.

2, when driving belt contacts with belt wheel, because of the distortion of chain, make driving belt outer rim elongation, and inner edge obtains compression and expand and increased driving belt frictional force, make driving belt more stable than common driving belt.

3, because this driving belt does not have elongation substantially, so after adjusting pretension, can tightly install by force in the use.

4, because this driving belt outer rim is provided with otch, so easier bending in the use work, institute so that transmission efficiency increase.

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is the utility model working state sectional view;

Fig. 2 is the utility model plan view;

Fig. 3 is the utility model sectional view;

Fig. 4 is the utility model sectional view.

As shown in Figure 1, at first press the roller chain of the size Selection appropriate size of driving belt, roller chain is wrapped in surrounding layer 1 and the packed layer 2 as strength layer, because strength layer reduced the driving belt stretchability, so the frictional force of driving belt is determined by pretension basically after replacing with roller chain, simultaneously the time through drive wheel, roller chain bending compressing driving belt inner edge produces distortion, and improves the transmission capacity of driving belt.

As shown in Figure 2, produce irregular breach because of bending for preventing driving belt when working, therefore at the vertical bearing pin 5 of driving belt outer rim, the place, axle center opens otch 4, and otch 4 will be deep to bearing pin 5.

As shown in Figure 3, the lower end of the otch of being offered 4 is that bearing pin 5 axial end will have a garden shape aperture 6, and the garden heart of garden shape aperture 6 is concentric with bearing pin 5, is deep to the axle head of bearing pin 5.

As shown in Figure 4, all to be full of filler in the gap of roller chain, even after driving belt ruptures like this, also can the driving belt disjunction be squeezed on roller chain and can not fall down, and driving belt can normally be used by filler.

The utility model can adopt the single row or multiple rows roller chain to adapt to multiple driving belt respectively according to difform driving belt.
