We offers a range of bushings for wind power applications. such as bearings and bushings in gearboxes and turbines. Manufacture self lubricating bearing bushing, bronze bearing bushing, bimetal bushing. Wind power equipment gear box copper ring, tin bronze copper bushing ring.

Engaged in the production and processing of various machinery with copper-based alloy parts and other general parts, and can be customized according to customer drawings or actual sample requirements of various copper bushings; the company uses centrifugal casting, sand casting, steel casting and other casting methods public. We can cast and process lead bronze, aluminum bronze, tin bronze, brass, high force brass, zinc-based alloy, aluminum alloy and other non-ferrous metals.

The gear box of wind turbine is the transmission part connecting the main shaft of the unit and the generator, and its main function is to transform the low-speed running input of the main shaft into the output required by the medium-speed or high-speed generator. The gearbox in the wind turbine is an important mechanical part whose main function is to transmit the power generated by the wind wheel under the action of wind to the generator and make it get the corresponding speed. As the unit is installed in the windy places such as high mountains, wilderness, beaches and islands, the working environment is harsh, and the natural environment in which the traffic is inconvenient, once there is a failure, it is very difficult to repair, so the reliability and service life of its various accessories including oil seals and floating oil distribution rings have raised much higher requirements than the general machinery.

Improper bearing selection or improper installation and use will lead to various damage and failure modes of bearings, and may even damage other parts in the gearbox. These damages and failures can directly or indirectly lead to downtime, affecting productivity and incurring unplanned replacement and maintenance costs.

According to the requirements of the use of wind power equipment gear box copper ring, our company produces wind power gear box copper sleeve material selection for tin bronze, tin bronze is casting shrinkage rate of small non-ferrous metal alloy, used to produce complex shape, clear contour, air tightness requirements of the casting. Tin bronze is very resistant to corrosion in the atmosphere, seawater, fresh water and steam, and is widely used in steam boilers and marine parts. Phosphor-containing tin bronze has good mechanical properties and can be used as wear-resistant parts and elastic parts for high precision workhorses. Leaded tin bronze is often used as wear-resistant parts and copper bushings. Zinc-containing tin bronze can be used as high airtight castings.

Tin bronze is widely used in the electrical and electronic industry, accounting for more than half of the total consumption. Used in various cables and wires, motors and transformers, switches and printed circuit boards In the manufacture of machinery and transport vehicles, used in the manufacture of industrial valves and fittings, copper rings, instruments, sliding bearings, molds, heat exchangers and pumps, etc. In the chemical industry, it is widely used in the manufacture of vacuums, distillation pots, brewing pots, etc.

The company with perfect production technology and testing equipment, scientific management mode, perfect research and development capabilities, strong manufacturing strength, perfect service system, unique corporate culture so as to better ensure product quality, the majority of users praise, has gradually become an influential enterprise in the copper bushing processing industry, welcome to drawings custom production.

Spindle bearings are the core components of the fan, fan spindle basically using rolling bearings. Recently, the news of sliding bearings instead of rolling bearings set off a pool of spring water in the industry. Sliding bearing friction is relatively small, especially adapted to the fan large-scale and cost reduction needs, we are working with a number of complete machine enterprises are jointly developed.”

Sliding bearing wind power industry. Sliding bearings may be applied in the future to part of the spindle bearing

” to slide bearings instead of rolling bearings”?

It is reported that the sliding bearing has the advantages of small radial size, strong bearing capacity, low cost, etc., can be applied to wind power spindle bearing, gear box bearings and other parts, significantly improve the bearing torque density, reduce the cost per unit torque.

The new shaft system of wind energy applications using sliding main bearings, its shaft system load density increased by more than 20%, strongly support the development of high-power models; sliding bearing split-flap design, partial replacement can be achieved, so that maintenance costs fall by more than 60%.

From the sliding bearing market segmentation, compared with the standardized rolling bearings, sliding bearings are currently in the rapid development period of application expansion and category enhancement.

Plain bearings help solve the problem of wind power cost reduction. Wind turbine using sliding bearings

The company has a more in-depth layout in the field of wind power self-lubricating bearings, and continues to carry out technical development and product production of wind power sliding bearings, and will be regarded as an important product line in the future. Supply and export of high precision sliding bearings, sliding bearing assemblies, components and wind power gearbox sliding bearing products, wind power sliding bearings to replace rolling bearings.

Sliding bearings in the industrial field is more mature application, in the wind power industry, especially the main shaft bearings as the core components of the wind turbine, the life and durability requirements are high, a new technology requires a long time to use, verification, and continuous improvement of research and development.”

Some of the bearings inside the gearbox use sliding technology, accounting for a relatively small percentage, and some of the technology is still in the common research and development stage.

In the gearbox bearing sliding bearings. In the drive chain optimization, sliding bearing is not necessarily a better solution, but the replacement of the gearbox sliding bearing, should be seen as a technical trend.

The replacement of gearboxes is in the fastest progress. As the company has mature applications in industrial gearboxes and has more technical accumulation, it is more advantageous to develop plain bearings in gearboxes. Secondly, the main shaft bearing has now completed material verification, and the yaw pitch bearing is also in the process of development.
