Noise Treatment of Gearbox

In mechanical work, noise treatment of gearbox is very necessary. Gearbox is an important component widely used in mechanical transmission. When a pair of gears engage, because of unavoidable errors such as pitch and tooth shape, there will be meshing impact during operation and noise corresponding to gear meshing frequency. Friction noise also occurs between [...]

Manufacturing Technology of Wind Power Gearbox

The manufacturing technology of wind power gearbox are usually carburized and quenched. Because of the large size and high precision of the gear ring of wind power gearbox, there is a big gap between the manufacturing technology of wind power gearbox ring in our country and the international advanced level, which is mainly embodied in [...]

The Role of Gearbox

The role of gearbox is very important. The high quality bearings are selected for the transmission part of gearbox, the skeleton oil seal for the sealing parts, the structure of sound absorbing box body, the larger surface area of box body and the large fan make the temperature rise and noise of the whole machine [...]

Speed-up Gearbox

Speed-up gearbox is an important mechanical component widely used in wind turbine. Its main function is to transfer the power generated by the wind turbine to the generator under the action of wind force and get the corresponding speed. Usually, the speed of wind wheel is very low, far less than the speed required by [...]

Production Process of Embedded Screw Sleeve

How is the embedded screw sleeve made? The first step in the production of embedded screw sleeve is blanking. The machine cuts all kinds of thick and thin columnar metal raw materials into equal length screw. Then is the rough processing process, through the machine drilling and other processes, a screw has been visible embryonic [...]

Design Experience of Hydraulic Valve Blocks

1. The shape of the hydraulic valve blocks is generally rectangular hexahedron. 2. Valve block material should be 35 steel forgings or continuous casting billets. 3. The large side length of the valve block should not be more than 600 mm, and the number of plug-ins of the two-way cartridge valve should not be more [...]

High Temperature Bearing Seat

Because the high temperature bearing seat should not only meet the requirements of high precision stamping bearing seat, but also meet the requirements of high temperature stamping bearing pedestal, the following two points should be taken into account when considering the fit and clearance of high temperature bearing seats: 1. Size change and hardness change [...]

Cleaning of Bearing Seats

Before the bearing seats are installed and guided, it should also be thoroughly cleaned and inspected. Scrape the dirt away with a scraper inside the bearing seat, wipe the dirt away with a cloth dipped in gasoline or solvent, and watch for cracks and sand holes to prevent oil seepage during operation. The joint surface [...]
