Why is the scooter belt driven?

1. The noise is small.

2. Do not adjust the tightness.

3. Easy to replace.

4. The transmission is stable, eliminating the vibration damping rubber in the rear hub.

First, the advantages and disadvantages of belt drive:

1. Advantages:

1 to mitigate shock, absorb shock, less noise, low cost, convenient maintenance and repair;

2 Change the transmission ratio.

Disadvantages:

1 belt drive is easy to slip, the transmission ratio is not accurate

2 poor heat resistance, poor resistance to overload, easy to aging

3 The transmission damping is large, especially when the vehicle is cold 4, the bearing is subjected to excessive lateral force.

The structural characteristics of the belt:

Its working surface is two oblique sides, and the inner layers of many belts are toothed, which is designed in consideration of the force of the belt when it is in the wrap angle position. When the belt is moving, the outer layer is stretched, and the inner layer is mainly subjected to the pressing force. Therefore, the inner layer of the belt is formed into a tooth shape, which is more suitable for the force of the belt in these working positions, thereby prolonging the belt. Service life.

To be simple, the advantages of belt transmission are wide range of center distance variation, simple structure, stable transmission, buffer load and safety protection. The disadvantages are large outer diameter, low efficiency, inaccurate transmission ratio and short service life.

In addition, the belt drive, the transmission ratio is not accurate but can be overload protected. Gear drive with precise transmission ratio but no overload protection. The gears can be reversed and the belts are not. Belt drive maintenance is simple

Second, the chain transmission features

The biggest advantage of the chain drive is its low cost and wide applicability. When the engine is braking, it can absorb a part of the vibration due to the many gaps between the links. The disadvantage is that the friction of the chain and the gear is easy to loosen the chain, the gear is worn, and the noise generated is high.

The direction of rotation of the chain and the direction of advancement of the car are as long as the generated torque is only to lift the front of the car, which has little effect on high-speed driving.

Third, there are the same black swan-like exceptions

Scooters are mostly belt drives, but they do not mean that there are no other transmission methods, such as chains or even shaft drives. The previous two continents of the New Continent Monster 50 were chained. In the gearbox, the oil was lubricated and the life should be long. A long time ago, the star 50, Dawn 50 is the shaft drive, Mulan 50, the celebrity 100 is the chain drive, but unfortunately has long been discontinued, Honda's retro turtle 50, there is a foot-mounted gear, four-speed automatic clutch chain Driven, I don't know much about it, but because of the design of the scooter, the belt drive is still mainstream.

The BMW C600 and C650GT, the engines of the two cars are also 650CC.

It uses the CVT belt section to connect the engine to the transmission section. The transmission part uses a chain drive and is lubricated by the oil pool, and the sound is small. The problem of low-speed slip and jitter of the scooter CVT belt transmission part is solved simply, and the CVT part is designed to be an intermediate part requiring a certain speed.

We offer processed lenses for laser processed machines. The performance is the same as the genuine goods and the price is a lot lower. That gets favorable reception of users who need cost-cutting. Also, for the processed lenses, we supply black lenses. These lenses cut cleanly, so production volume will be increased with high-speed cutting. That will be the big help for your sales growth.

We offer laser optics, mirrors, cutting lens and focus lens forAmada, Bystronic, Cincinnati, Mitsubishi, Mazak and TrumpfLaser CuttingMachines.

Laser optics

From rear mirrors to focusing lenses and every optical component in between, we offer CO2 laser optics such as focusing lenses, parabolic mirrors, curved mirrors, collimators, reflective phase retarders, rear mirrors, output couplers and output windows (glass covers / protective windows).

Our suppliers include world-leading II-VI (Two-Six) infrared accounting for well over 80% of the world market in laser optics for CO2 lasers. Of course, we have a number of other suppliers for non-CO2 beam path components.







Products

Lenses for high power CO2 laserscollimating_optics.jpg are suitable for all manufacturers in the world market. The lenses consist of Zinc Selenide (ZnSe), which is toxic and potentially radioactive if the lens malfunctions. One should therefore handle a lens breakdown with great care. Special instructions for this can be downloaded here on our website.
