Description

Technical Field

[0001] The utility model relates to a turning tool, in particular to a turning tool for a large tapered roller bearing. Background Art

[0002] Wind turbine bearings are a special type of bearings, most of which use tapered roller bearings. They are used in harsh environments, have high maintenance costs, and require a long life. Wind turbine bearings are the hub of all moving parts of wind turbines. As the core component of wind turbines, wind turbines are subject to complex forces and vibrations. They must be able to withstand huge impact loads and work in corrosion, sand, humidity, and low temperature environments. At the same time, they must meet the requirements of 20 years of service life and high reliability. Therefore, bearings need to be tested after they are produced to check the yield rate and ensure accuracy.

[0003] At present, when testing bearing components, they are tied with slings after testing one side, lifted by a crane, and then turned over for testing. Since wind turbine bearings are huge and weigh more than 200kg, the slings will tighten when they are lifted, causing the component cage to deform, and the rollers and raceways to be squeezed to produce indentations, resulting in failure in subsequent tests.

The first cover 101 and the second cover 102 are combined to form a tool 1, and the first cover 101 and the second cover 102 are detachably connected through the connecting assembly 3 to fasten the tool 1. The top and bottom of the first cover 101 are arc-shaped, and the top and bottom of the second cover are also arc-shaped, and the lifting ring 4 is fixedly connected to the top of the first cover 101. The first protective cover 9, the second protective cover 10, and the third protective cover 11 can be replaced according to the degree of use or the way of use.

[0020] The first cover 101 and the second cover 102 are symmetrically provided with fixing grooves 2 on both sides of the periphery, and the connecting assembly 3 is provided in the fixing groove 2. The connecting assembly 3 is a bolt assembly, and the connecting assembly 3 includes two pairs of connecting members symmetrically provided in the fixing groove 2, and the four groups of connecting members are perpendicular to the joint surface of the first cover 101 and the second cover 102. The first cover 101 and the second cover 102 form a tooling 1 as a whole through the bolt assembly fixed in the fixing groove 2, and the bolts can be removed for separation when necessary.

[0021] A first groove 5 is provided in the first cover body 101, and the first protective cover 9 is fitted in the first groove 5, wherein a portion of the first groove 5 is opened at the bottom of the first cover body 101, and another portion is opened at the side wall of the first cover body 101.
