1. Helical gearing
helical gear is not completely helical gear, helical gear is two helical gear meshing way, by them in a different direction in the heritability in space.Ordinary spur gear along the tooth width into the mesh at the same time, thus impact vibration noise, transmission is not stable.Helical gears adopt high quality high strength alloy steel, the surface carburizing hardening treatment, carrying capacity is strong, durable.
the advantage of helical gear mesh: (1) sex good, smooth transmission, low noise.(2) the contact ratio, reduces the load of each pair of gear, improve the bearing capacity of the gear.(3) does not produce root cutting teeth at least less.
the tyre is grounded on the all kinds of vehicles or machinery assembly rolling circular elastic rubber products.Usually installed on the metal rim, can support the body, the buffer external shocks, realization of contact with the road surface and ensure the vehicle driving performance.
the tyres are often used under the condition of complex and demanding, it when driving under various deformation, load, force and the function of the high and low temperature, so you must have high load-bearing performance, traction performance and buffer performance.At the same time, it also requires high abrasion resistance, flexing resistance, and low rolling resistance and thermal resistance.The world consumes half the amount of rubber for tire production, visible using the ability of rubber tires.
3. Gear drive
gear transmission is the most widely used in mechanical driving a form of transmission.Its transmission is more accurate, high efficiency, compact structure, reliable operation, long service life.Indicators of gear technology can achieve at present: circumferential velocity v = 300 m/s, rotational speed n = 10 r/min, transfer the power of P = 10 kw, modulus m = 0.004 ~ 100 mm, d = 1 mm to 152.3 mm in diameter.
gear transmission is to use two gear teeth meshing transmission power and movement of the mechanical transmission.According to the relative position of the gear axis parallel to the axis of cylindrical gear transmission, intersecting shaft cone gear drive and the staggered shaft helical gear transmission.With compact structure, high efficiency, long service life, etc.
4. Universal joint
cardan universal joint, is to realize the change point of power transmission parts, used to need to change the location of the drive axis direction, it is the universal transmission device of car driving system of "joint" part.Universal joint and combination of transmission, known as the universal joint transmission device.
in the front engine rear wheel drive vehicles, universal transmission device installed in between the gearbox output shaft and drive axle of main reducer input shaft;And front engine front-wheel drive vehicles omit the transmission shaft, universal joint is installed in the steering system is responsible for driving and responsible for between front axle and half axle and the wheel.
5. Another kind of universal joint, this part didn't see what is
the following a few small make up what is didn't see it, who knows?
