Description

A bearing chamber production polishing device with clamping function

Technical Field

The invention relates to the technical field of wind power generator sets, in particular to a bearing chamber production polishing device with a clamping function.

Background technique

Special bearings for wind turbines Bearings for wind turbines can be roughly divided into three categories, namely yaw bearings, pitch bearings, and transmission system bearings (main shaft and gearbox bearings). Yaw bearings are installed at the connection between the tower and the cabin, and pitch bearings are installed at the connection between the root of each blade and the hub. Each wind turbine equipment uses one set of yaw bearings and three sets of pitch bearings. Some wind turbines below the megawatt level have non-adjustable blades and do not need pitch bearings.

For this purpose, the China Patent Network has published a polishing device for the production of wind turbine bearing chambers with the publication number CN115229652B, which includes: a mounting platform, a control terminal, an inner polishing mechanism, a first lifting module, an outer polishing mechanism, a second lifting module, a driving roller, a mounting frame, a pushing module and a limiting roller; the inner polishing mechanism is arranged in the middle of the front side of the top end of the mounting platform along the front-back direction; the first lifting module is arranged at the top end of the mounting platform through a bracket and is located at the left rear of the inner polishing mechanism, and the first lifting module is electrically connected to the control terminal; the outer polishing mechanism is arranged at the lifting end of the first lifting module. The bearing chamber production polishing device with a clamping function can be used for polishing wind turbine bearings of different diameters, and can simultaneously polish multiple surfaces of wind turbine bearings;

However, there are still the following disadvantages: the device limits the bearing chamber by rollers when grinding it, and the limiting effect of the rollers themselves is poor. In addition, the rotation of the polishing device during grinding may cause a slight deflection of the bearing chamber itself, thereby affecting the polishing effect;

Therefore, the design is highly practical and by providing a limiting part, the bearing chamber can be further clamped after it is clamped and fixed, so that it can be more stable when fixed. During grinding and polishing, the grinding block is inside the bearing chamber, and the surface of the grinding block is in compression contact with the inner wall of the bearing chamber. When the bearing chamber rotates, the bearing chamber will rotate slightly due to its own rapid rotation, thereby affecting its grinding and polishing effect. When the clamping plate contacts the surface of the bearing chamber, the first airbag is squeezed, and when the first airbag is squeezed, the second airbag is expanded, so that the surface of the lateral limiting plate is in contact with the surface of the bearing chamber. A bearing chamber production and polishing device with a clamping function is very necessary.

(1) By providing a fixing mechanism, the inner wall of the bearing chamber can be fixed when it is being polished, thereby preventing the bearing chamber from moving during polishing, resulting in a lower smoothness of the polished surface, requiring secondary polishing, and reducing the efficiency during the polishing process. By providing a clamping portion, the surface of the bearing chamber can be clamped and fixed during polishing.

(4) By providing a polishing mechanism, the bearing chamber can be polished after being clamped and fixed, and before polishing, the two polishing blocks can be controlled to extend into the bearing chamber, and the distance between the two polishing blocks can be adjusted according to the size of the bearing chamber itself, so that the polishing can be less restrictive. During adjustment, the elastic force of the first elastic member can make the surfaces of the two polishing blocks always in contact with the inner wall of the bearing chamber, making the polishing more uniform. By providing a slide rail and a limit plate, the polishing blocks can always be in a horizontal state during adjustment.
