Choose the five advantages of synchronous belt transmission

Synchronous belt transmission is composed of a root surface with spacing within weeks of closed loop tape and have appropriate tooth of pulley, as shown in figure 1 _1.Operation, with the convex teeth with tooth engages groove, to transmit motion and power.And other transmission coarse than, synchronous belt transmission has the following advantages:

1. The non-slip at work, have accurate transmission ratio

Synchronous belt transmission is a kind of meshing transmission, while the synchronous belt is elastomer, but as a result of which bear the load carrying rope under tension is not elongation characteristics, so it can keep the belt pitch unchanged, belt and the tooth groove meshing correctly, no slip of the synchronous transmission, obtain accurate transmission ratio.

2. High transmission efficiency, energy saving effect is good

Because be non-slip synchronization synchronous belt transmission, reason has high transmission efficiency, generally can reach 0. 98.It compared with the triangle belt transmission, has obvious energy saving effect, the following examples as evidence available.

See from the above several cases, the synchronous belt transmission has great potential in energy saving, so the synchronous belt transmission can obtain higher economic benefits.

3, large range of transmission ratio, compact structure

Synchronous belt drive transmission ratio can reach 10 or so commonly, and in the case of large transmission ratio, compact structure than the triangle belt transmission.For synchronous belt transmission is meshing transmission, the pulley diameter than rely on the friction to transfer power triangle belt wheel is much smaller, moreover because of the synchronous belt don't need big tension, reduce the size of the wheel shaft and bearing can be.So compared with triangle belt transmission, under the same transmission ratio, the synchronous belt transmission is of compact structure.

4, easy maintenance, low operation cost

Because carrying rope used in synchronous belt elongation small glass fiber, steel wire and other materials, so in the process of operation with long zhong is very small, do not need such as triangle, chain often adjust the tension.In addition, the synchronous belt also does not require any lubrication in the work, so the maintenance is very convenient, running cost is lower than v-belts, chain, gear is ok.

5, work well under the condition of bad environment

Impurities in the dust, water and corrosion medium under bad working conditions, the chain is easy to rust, wear and tear, triangle produces sliding, and the synchronous belt transmission is able to adapt to these conditions.Since it is meshing transmission, under the condition of rain not sliding, and the water is good lubricants, rubber may reduce the wear of belt.When dust impurities, because toothed synchronous belt into the pulley groove, toothed will squeeze in wheel groove in the air, make the compressed air to the wheel groove on both sides of the discharge, the air squeeze will also have the effect of cleaning mesh surface, take away the dust impurities, thus reducing the wear and tear of the synchronous belt.In addition synchronization with high corrosion resistance, heat resistance, under the condition of high temperature, corrosion gas can still work normally.

3, tooth synchronous belt use in \"climbing\" phenomenon

Although there are many advantages of synchronous belt transmission, but also has many flaws, short service life, wear-resisting, tooth stripping phenomenon is serious, as well as the meshing, skip, vibration.

With synchronous belt transmission process and transmit motion produced by the transmission error, synchronous belt on tooth profile will appear on the surface, because of the several times of N accumulation error. It can make the top round toothed climb on pulleys, synchronous cog belt on the pulley top circle sliding tooth. This is called \"climb\", \"phenomenon;

In addition to the above reason may produce \"climb\" phenomenon, there are:

3.1 synchronous belt tension is too small

3.2 or tooth synchronous belt wheel surface with oil

3.3 transmission of toothed wheel are not at the same level with toothed wheel (that is, the parallel degree error);

3.4 synchronous cog belt belongs to the elastomer, in the process of manufacturing and force changes with tooth pitch, synchronous belt tooth and tooth in meshing time distance, appears the pitch error.Excessive pitch error, can make the drive is not smooth, vibration and climbing gear phenomenon;

3.5 starting frequently and have a shock load, lead to jump out from toothed belt tooth groove, also can produce climbing gear

3.6 application of synchronous cog belt must prevent overload, otherwise also prone to \"climb\" phenomenon.

This \"climb\" phenomenon for textile equipment, such as: drawing frame, carding machine, roving frame, and so on, is very harmful.

And \"climb\" phenomenon is one of the important causes of mechanical wave is produced.This is one of the main topics of the mechanical wave big discussion we are!Moreover, this kind of \"climb\" phenomenon is often irregular, so sometimes will produce \"multiple mechanical wave\", this kind of \"multiple mechanical wave\", and sometimes no difficult to find its trace.This is to solve the complexity of mechanical wave, ghosts and the secret and difficult!

4 to solve the tooth synchronous belt \"climb\" problem in use

4.1 to guarantee the accuracy of the drive, we must make the pitch synchronous toothed manufacturing precision with tooth pitch is equal.

4.2 solve the manufacturing of pitch error and accumulated error '

4.3 appropriate additive tension: synchronous belt transmission to a proper tension type (such as FA317A drawing frame product manuals enclosed is the tension adjustment);

4.4 ensure synchronous belt and tooth profile wheel surface can't have any stain

4.4 toothed wheel and tooth profile wheels must ensure the parallelism in the manufacture, installation;

4.5 to solve the vibration of synchronous belt, frequent starting, too

4.6 on a regular basis to the cog belt, toothed wheel surface cleaning and maintenance in anhydrous ethanol

4.7 regular inspection on cog belt tension;

4.8 the combination of semi-product mechanical wave detection wave spectrum analysis, find and solve problems in a timely manner
