The earliest period of development of all-steel radial tires in China dates back to the 1960s. However, no substantive progress was made at the time based on the gap in technology and equipment.

The real development of China's all-steel radial tires should be around the beginning of the 21st century, and it must achieve rapid development after the turn of the century. The popularity of meridianization has grown significantly, from less than 30% to about 90%, which is a quantum leap forward. .

The development of all-steel radial tires is mainly affected by two major aspects: one is external influence factors, and the other is internal product advantages. Focus on this two aspects of analysis.

China's All Steel Radial Tire Industry Enters the Consolidation Period and Obtains Better Development
The domestic all-steel radial tire industry has achieved better development in the integration period

External influence

The external influence factors mainly come from the external influences of the industry. Many policies and norms are used to supervise the overall change of the industry. The main influence factors are as follows.

First, on December 28, 2000, the relevant state authorities issued a notice on “Exemption of Consumption Taxes on Tire Carriages in Tire Tax Items”. While other types of tires are still unable to escape the fate of “financially valuable products”, they are forced to pay 10% of the consumption tax on tires of tire production companies while paying 17% of value-added tax.

As a result, the policy adjustment laid the foundation for the increase in the production of all-steel radial tires in the later period, thus also inhibiting the expansion of the production of tax enterprises and, to a certain extent, supervising the upgrading of the products of enterprises with conditional changes.

Second, in September 2010, the Ministry of Industry and Information Technology issued the “Tire Industry Policy” announcement. According to the industrial development plan, by 2015, the radialization rate of domestic passenger tires will reach 100%, the radialization rate of light-duty truck tires will reach 85%, and the radialization rate of heavy-duty trucks will reach 90%.

Internal advantage

The advantage of intrinsic products refers to the irreplaceable development advantages of all-steel radial tires with other varieties of tires, mainly in the following aspects.

First, the service life is longer. Since the all-steel radial tire has a belt with a greater rigidity between the tread and the carcass ply, when the tire rolls on the road, the circumferential deformation is small and the relative slip is small. Because of the large radial elasticity of the tire carcass, the ground contact area of ​​the tire is increased and the pressure is reduced. Therefore, the tread has strong wear resistance, and its mileage can be 30% more than that of ordinary tires.

The second is low rolling resistance and low fuel consumption. Because all-steel radial tires have a small number of plies, a low driving temperature, fast heat dissipation, and small circumferential deformation, the rolling resistance is 15%-20% smaller than that of ordinary tires, and the taxi distance is about 25% more.

The third is large carrying capacity. Since the arrangement of the all-steel radial tire cords is in line with the main deformation direction of the tires, the strength of the cords can be fully and effectively used, and therefore the load capacity of the tires is more than 10% higher than that of ordinary diagonal tires.

Fourth, shock absorption performance is good. Due to the radial elasticity of the all-steel radial carcass, the radial (vertical to the direction of the ground) deformation is large, and the impact of the uneven road surface can be mitigated.

Overcapacity appears

In this way, the all-steel radial tires ushered in the development of "good weather and favorable conditions." However, as the industry progresses unrestrainedly and expands production capacity without restraint, the problems also arise.

"This expansion of production capacity, this kind of growth, really good?" Since 2010, China's tire industry has issued such a question.

In fact, the development of the Chinese tire industry has indeed encountered some problems. This is the industry’s most feared and most hurt “overcapacity”. It's not the business that is feeling this pressure quietly, and it's more that this kind of excess crisis has begun to radiate the industry, allowing companies to be selected and eliminated in the industry's survival.

In the face of such a supply-demand pattern, tire manufacturers began to falter, market sales began to fear, and tire profits began to shrink.

In particular, in 2014, the Shandong Provincial Government issued a notice to limit new and newly-increased production capacity, which imposed certain mandatory pressure on local tire production capacity. This kind of coercion does indeed deter new businesses in the industry, making it no longer easy to grow in the past two years.

Stopped or suspended all-steel tire project

Into the stop period

From the statistical data, it can be seen that tire companies in Shandong still have absolute advantages in new production capacity, but the process is relatively slow, and some have not started yet.

It is understood that some of these companies have failed to approve the new projects, partly because of the lack of start-up funds and their inability to start, and partly because the current market is under so much pressure that companies are temporarily taking a wait-and-see attitude and suspending the start-up process. .

The transformation between ideals and reality is always a result of having a dream and becoming beautiful, but also becomes boned by reality. Judging from the current market operation situation, it is difficult for new tire companies to enter the market and the risk assumed later is greater.

From the current point of view, the Chaoyang period of the all-steel radial tires has been gradually dying, leaving more new regulation of the industry's reintegration. This is not to say that the domestic tire industry has entered a period of sluggish decline, and more is the industry's entering into the rest period.

This kind of stoppage is more focused on sorting out the pros and cons of the industry, abandoning the ineffective production capacity, and at the same time, it will also give more opportunities for the development of the enterprise.

The growth rate of China's all-steel radial tires has entered a rational and balanced state. The reorganization of the industry and the re-matching of demand will be an unshakable development task in the next five years.

At this time, no one can make a certain conclusion for the tire industry, and more is to give time for self-recognition, self-reform and self-transformation, not to make the main force of the industry lose the correct direction of development after the big waves break the sand.

Rotary drive, is an integrated whole circumference rotary driving power source speed reducer, its Slewing Bearing as the transmission mechanism and the follower attachment, driving unit, driving source and shell through a circle on the slewing bearing inner and outer ring in the attachment, and the other is a circle as the driven again, as the connecting base driven working parts, characteristics of such use of slewing bearing itself is the whole week rotary joints, efficient allocation of driving power source and the main driving parts, making it a set of rotary, deceleration and driving functions but also has the advantages of simple structure, convenient manufacture and maintenance of general reducer institutions.

According to transmission form of rotary drive, the drive can be divided for rotary gear and worm rotary drive, gear transmission and inheritance characteristics of worm drive with each other, these two kinds of rotary drive respectively can adapt in high speed and low speed applications, in terms of carrying capacity, better than the performance of the gear worm type. And when using the enveloping worm drive, its bearing capacity, deformation resistance and rigidity have further improved, but the worm gear rotary drive in terms of efficiency is inferior to the rotary drive gear.
According to the opening of the rotary drive mechanism gearing to distinguish, can be divided into open and closed drive rotary, usually open structure for environment is too harsh, and maintenance of application cycle is short, the open parts of the structure is convenient for inspection and maintenance, but also more convenient to replace. On the other hand, the closed structure can provide longer maintenance life cycle in the situation where the environmental conditions are not changed and the environmental pollution level below medium is below.

Modularization
Due to the high integration of rotary drive, users do not need to purchase and process every accessory that constitutes a rotating device, to a certain extent, it also reduces the preparatory process at the beginning of product production, thereby greatly improving labor productivity.
Safety
The worm and worm drive has the characteristic of self - locking in reverse. It can be locked in the opposite direction, that is, the worm drive can only be driven by the worm, but the worm can not drive the worm. This characteristic makes the slewing drive widely used in lifting and aerial operation equipment, while improving the technology content of the host, it also greatly improves the stability of the host and the safety factor of the operation. Compared with the traditional rotary products, the rotary drive is easy to install, easy to maintain, and to save the installation space in a greater degree.
Simplified host design
Compared with the traditional gear transmission, worm gear drive can get a relatively large reduction ratio, in some cases, it can save the reducer parts for the main engine, thereby reducing the purchase cost for the customers, and greatly reducing the failure rate of the main engine.
