Automotive power steering is part of a vehicle’s steering system. The main function of a power steering gear is to convert rotational motion of the steering wheel into linear motion and thus control the direction of the wheels. Power steering gears are present in both hydraulic power steering and electronic power steering systems. The rack and pinion gear system consists of two gears: a circular gear called pinion and a linear gear called rack. As a rotational force of steering wheel is applied to the pinion, the teeth of the pinion moves the linear rack. Thus, the rack and pinion gear system converts rotation motion into linear motion and controls the direction of the steering wheel. In recirculating ball power steering gears, the worm gear is attached to the end of a steering column. A ball nut rack is mounted on Cone Crusher Parts Manufacturers the worm gear. Two sets of balls are provided in the grove of the worm gear and ball nut rack. The balls helps in reducing friction during the movement of the nut rack on the worm gear.
The nut rack is provided with teeth outside and is connected to the pitman arm. When rotation force of the steering wheel is applied, the ball nut racks move in a linear fashion. Thus, rotation motion of steering wheel is converted to linear motion and controls the direction of the steering wheel. Rack and pinion gears are generally found in passenger vehicles and light commercial vehicles and recirculating ball power steering gears are found in heavy commercial vehicles. By type, the market is segmented into rack and pinion gear and recirculating ball power steering gears. The automotive power steering gear market is of two types: original equipment (OE) type and aftermarket type.
By vehicle type, the market is classified into passenger vehicles, light commercial vehicles (LCVs) and heavy commercial vehicles (HCVs). By type, the market is divided into North America, Europe, Asia Pacific, Middle East & Africa, and Latin America. North America is a major automotive power steering gears market. The growth of the market is more than Europe and other regions but less than Asia Pacific. The U.S. is the largest market in this region as it is the second largest automotive and passenger vehicles market in the world. Canada and Mexico are other major markets in this region. Europe is also one of the largest automotive power steering gears market in the world. Germany is the largest market in this region as it is the largest automotive market in Europe and its passenger vehicle market is fourth largest in the world. The U.K, France, Italy, Spain, Belgium and Netherlands are other key markets in this region.
The automotive power steering gear market growth rate in Europe is less than the U.S. Asia Pacific is the largest automotive power steering market in the world. China is the largest market in this region as it is the dominant automotive and passenger vehicle market in the world. Japan and India are major markets in this region as they are the third and fifth largest passenger vehicle markets in the world. South Korea and Australia are other prominent markets in this region. The automotive power steering gear market in Asia Pacific is growing at the fastest rate among all the regions. Middle East & Africa is another significant automotive power steering gears market led by Turkey, Iran and South Africa. Latin America is another major automotive power steering gears market, dominated by Brazil and Argentina. Rising demand for passenger vehicles across the world is anticipated to increase the demand for power steering gears in the global automotive market.
According to government figures hip fractures cause more than 1150 premature deaths each month in the UK. By the age of 75 around half the population have osteoporosis, because as we get older our bones become more fragile and likely to break or fracture. Your risk is dependent on many factors including family history, race, gender, certain medical conditions and drugs, and your age. You can't do anything about changing most of those, but you can do something to help prevent osteoporosis. The first question is diet, and it increases your osteoporosis risk if you babbitt bearing suppliers crash diet or have a very low body weight as you body takes the calcium it needs from your bones if you are not providing it in your diet. Some foods are very calcium-rich and so are beneficial in helping bones stay strong. These are: Low-fat or non-fat dairy products, tinned sardines and tinned salmon, dark green vegetables, tofu, almonds, figs, sesame seeds and calcium-fortified fruit juices and soy milk.
If you can't stomach any of those, then get a good calcium/magnesium supplement - not just calcium alone as you need the magnesium for maximum calcium absorption. . Magnesium deficiency can be quite common in osteoporosis and although many fruit and vegetables have some magnesium in them, the best sources are whole grains, wheat bran, leafy green vegetables, nuts (almonds are a very rich source of magnesium and calcium), bananas and apricots. You also need trace minerals: Boron from apples, almonds, pears and green, leafy vegetables and manganese from ginger, buckwheat and oats. Collagen is a vital factor in having healthy ligaments, tendons and bones and for so are zinc, copper, beta carotene and vitamin C so if you are taking a multivitamin make sure those are all included. Exercise is also important, and it's never too late to start.
The key factor is that it must be weight bearing such as walking, dancing, playing tennis. Tai Chi and Yoga are also very beneficial, but swimming although an excellent cardiovascular workout is not weight bearing and so won't help prevent osteoporosis. I am a great believer in using natural hormones to help with osteoporosis and this is work that was pioneered in the USA by the late Dr John Lee. He prescribed natural progesterone cream to his patients and kept a faithful record of their bones scans over the course of treatment. He saw a substantial improvement in bone density and soon became an outspoken proponent of its use, not something that endeared him to the medical profession! I myself set up the Natural Progesterone Information Service in the 1990's as I believed very firmly in his work, and helped pass on his great results to many women, and some enlightened doctors.
Many women take HRT in the belief that it will help or prevent osteoporosis, and for a short time it will delay bone loss. Over time, however, that ability reduces and what is really needed is the hormone that actually builds bone. That is progesterone and unless that is introduced into any treatment regime then can be no improvement in bone density, which is the only real test of whether osteoporosis is being reversed or halted. If you believe you are at risk of osteoporosis because of any of the risk factors I have mentioned, then speak to your GP about having a scan. Unfortunately osteoporosis has no outward signs to catch it in the early stages - it cannot be diagnosed from looking at you, or talking to you. The 'symptom' most easily seen is when a bone breaks under slight pressure or there are a number of breaks in a short period of time. Prevention makes good sense, so have plenty of exercise, eat calcium rich foods and investigate the role of natural hormones in building bone if you want to minimize your risk for osteoporosis. .
