Description

Technical Field

[0001] This utility model belongs to the field of bearing technology, specifically relating to a tooling for heating and assembling the retainer of a tapered roller spindle bearing, applicable to wind turbine tapered roller spindle bearings. Background Technology

[0002] With the continuous development of the wind power industry, the power of wind turbines is constantly increasing. Wind turbine bearings are one of the essential components of wind turbine generator sets. The main shaft bearing is responsible for supporting the main shaft of the wind turbine generator and transmitting loads, which is of paramount importance. However, the processing and assembly of the main shaft bearing has extremely high requirements and is extremely difficult. In particular, the heating and assembly of tapered roller main shaft bearings is extremely difficult. If the retainer deforms during the heating process, it will cause the rollers or rings to fail to be assembled properly, or even lead to the scrapping of the product. Utility Model Content

[0003] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to propose a tooling for heating and assembling the retainer of a tapered roller spindle bearing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fixture for heating and assembling a retainer of a tapered roller bearing includes a support base; a limiting baffle is connected to the support base; the limiting baffle has an L-shaped cross-section; a heating coil for heating the retainer is placed between the limiting baffle and the retainer; the limiting baffle is movably connected to the support base by connecting bolts; the top surface of the support base has a T-shaped notch for placing a T-shaped block, and the T-shaped notch is inverted; the limiting baffle is fixedly connected to the T-shaped block placed in the T-shaped notch by connecting bolts; the support base and the limiting baffle are fastened together by the T-shaped block and connecting bolts to form a support and limiting device, which works in conjunction with the heating coil to heat the tapered roller bearing retainer.

[0006] The surface of the limiting baffle that contacts the heating coil is an inclined surface; the surface of the limiting baffle that contacts the support base is the bottom surface, and the bottom surface has a light hole for the connecting bolt to pass through; the T-block has a threaded hole for threaded engagement with the connecting bolt.

[0007] This utility model proposes a tooling for heating and assembling the retainer of a tapered roller spindle bearing. By adopting the above technical solution, the retainer of the tapered roller spindle bearing can be effectively heated, and deformation of the retainer can be prevented during the heating process, thereby improving the assembly efficiency of the tapered roller spindle bearing.

[0014] The present invention will be described in conjunction with the accompanying drawings and specific examples:

[0015] like Figure 1 , Figure 2 As shown, a tooling for heating and assembling a retainer of a tapered roller spindle bearing includes a support base 1, a T-block 2 with a threaded hole, a limiting baffle 3, connecting bolts 4, and a heating coil 5; the support base 1 has a T-shaped notch 8 in the middle of its seat surface, allowing the T-block 2 with the threaded hole to be inserted; as shown... Figure 1 , Figure 5 As shown, the bottom plate of the limiting baffle 3 has a light hole in the middle that is slightly larger than the threaded hole of the T-block 2. After the T-block 2 is embedded into the support base 1, the limiting baffle 3 and the T-block 2 embedded in the support base are fastened together by using connecting bolts 4, thus forming a support limiting device. After six such support limiting devices are evenly distributed around the circumference according to the size of the retainer, the retainer 7 to be heated is placed steadily on the support base 1 with the small end facing down, and then the heating coil 5 is placed in. Then, by adjusting the T-block 2, the heating coil 5 is made to fit tightly against the retainer to be heated, thereby achieving heating of the retainer and effectively preventing deformation of the retainer.

[0016] By using the above-mentioned utility model, the heating of the retainer of the tapered roller spindle bearing can be effectively carried out, and deformation of the retainer during the heating process can be prevented from causing assembly failure, thus greatly improving the assembly efficiency of the tapered roller spindle bearing.
