Description

Technical Field

[0001] This utility model relates to the field of installation equipment technology, specifically to an installation device for generator bearings. Background Technology

[0002] A generator rotor assembly typically consists of components such as a rotor core and windings, and has a certain weight. Bearings are mounted on the shaft and can support the weight of the rotor assembly, allowing it to be stably suspended inside the generator stator.

[0003] Currently, existing technologies for installing generator bearings typically require limiting the generator rotor assembly, then fitting the rotor assembly shaft to the bearing, and using a specific bearing pressure ring to apply downward pressure to the bearing for installation and alignment. However, traditional methods for fixing the rotor assembly use clamping blocks, which are slow and require manual alignment. Furthermore, due to the variety of rotor assembly shaft types and thicknesses, some thinner shafts are poorly clamped, leading to potential wobbling during subsequent bearing installation and posing installation risks. To address these shortcomings, this invention provides a generator bearing installation device to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an installation device for generator bearings. The positioning base design allows the rotor assembly to be easily and quickly clamped into the shaft groove for initial positioning during clamping and limiting. The design of the V-shaped clamp and adjustment unit facilitates easy adjustment of the V-shaped clamp, quickly clamping and limiting the rotor assembly shaft. When the shaft is thin and the clamping is unstable, a second clamp and control unit design provide secondary reinforcement, ensuring stable clamping and preventing shaking during subsequent bearing installation, thus meeting usage requirements.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an installation device for a generator bearing, comprising a device base, an electric push rod, a lifting platform, a positioning base, a V-shaped clamp, an adjustment unit, a second clamp, and a control unit;

[0009] The V-shaped clamping block is disposed inside the positioning base;

[0010] The adjustment unit is mounted on the positioning base and is used to adjust the position of the V-shaped clamping block;

[0011] The second clamping block is disposed inside the V-shaped clamping block;

[0012] The control unit is located on the V-shaped clamp and is used to adjust the position of the second clamp.

[0014] The track seat is mounted on the positioning base;

[0015] The slider is slidably connected within the track seat and connected to the V-shaped clamp;

[0016] The motor is mounted on the track base;

[0017] A bidirectional screw is located at the output end of the motor and is threadedly connected to the slider.

[0018] Preferably, the control unit includes:

[0019] An adjustment seat is provided on the V-shaped clamp;

[0020] The lead screw is threaded onto the adjusting seat and rotatably connected to the second clamping block.

[0021] Preferably, the lead screw is provided with a rotating handle.

[0022] Preferably, the V-shaped clamping block has a slot corresponding to the second clamping block, and the slot is connected to the inner cavity of the adjusting seat.

[0026] This utility model discloses an installation device for generator bearings, which has the following beneficial effects:

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] This application provides an installation device for generator bearings, which solves the problem that the traditional fixing method for rotor assemblies uses clamping blocks for clamping, which is slow and requires manual alignment. In addition, because rotor assembly shafts come in various models and thicknesses, some thinner shafts are not clamped effectively.

[0036] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example 1

[0037] This utility model discloses an installation device for a generator bearing, according to the attached... Figure 1-4 As shown, it includes a device base 1, an electric push rod 2, a lifting platform 3, a positioning base 4, a V-shaped clamp 5, an adjustment unit 6, a second clamp 7, and a control unit 8;

[0038] Equipment base 1 serves as the supporting foundation for the entire generator bearing installation equipment, providing a stable installation platform for other components and ensuring the overall stability of the equipment structure.

[0039] The electric push rod 2 is mounted on the equipment base 1. During use, the electric push rod 2 is powered by the control circuit, causing its output end to generate linear motion, which provides power for the lifting of the lifting platform 3.

[0040] The lifting platform 3 is located at the output end of the electric push rod 2 and rises and falls with the movement of the electric push rod 2. The lifting platform 3 is equipped with a bearing pressure ring 31, which is used to apply pressure to the bearing and press it into the shaft of the generator rotor assembly.

[0041] The positioning base 4 is set on the equipment base 1, and a shaft groove 41 corresponding to the shaft of the rotor assembly is opened on it to limit the shaft of the rotor assembly so that the rotor assembly is accurately positioned when the bearing is installed.

[0042] V-shaped clamping blocks 5 are located inside the positioning base 4. Their V-shaped structure can better fit the shaft of the rotor assembly and clamp and position the shaft from two directions.

[0043] The adjustment unit 6 includes a track seat 61, a slider 62, a motor 63, and a bidirectional screw 64. The track seat 61 is mounted on the positioning base 4, the slider 62 is slidably connected to the track seat 61 and connected to the V-shaped clamp 5, the motor 63 is mounted on the track seat 61, and the bidirectional screw 64 is mounted on the output end of the motor 63 and threadedly connected to the slider 62.

[0044] In use, the motor 63 drives the bidirectional screw 64 to rotate. Since the bidirectional screw 64 is threadedly connected to the slider 62, and the slider 62 is restricted by the track seat 61 to slide in a straight line, the slider 62 drives the V-shaped clamp 5 to move within the track seat 61, thereby adjusting the position of the V-shaped clamp 5 to adapt to rotor assembly shafts of different sizes and improve the versatility of the equipment.

[0045] The second clamping block 7 is located inside the V-shaped clamping block 5 and cooperates with the V-shaped clamping block 5 to further clamp and fix the shafts of rotor assemblies of different sizes, enhance the fixing effect on the shafts, ensure that the shafts will not loosen or rotate during the installation of bearings, and guarantee the installation quality.

[0046] The control unit 8 includes an adjusting seat 81, a lead screw 82, and a rotating handle 83. The adjusting seat 81 is mounted on the V-shaped clamp 5, the lead screw 82 is threaded onto the adjusting seat 81 and rotatably connected to the second clamp 7, and the rotating handle 83 is mounted on the lead screw 82.

[0047] In use, the operator rotates the handle 83, causing the lead screw 82 to rotate. Since the lead screw 82 is threadedly connected to the adjusting seat 81, and the second clamping block 7 is restricted to linear movement by the internal structure of the V-shaped clamping block 5, the second clamping block 7 moves within the V-shaped clamping block 5, allowing for position adjustment and more precise fixing of the rotor assembly shaft. Simultaneously, the V-shaped clamping block 5 has a slot 51 corresponding to the second clamping block 7, which communicates with the inner cavity of the adjusting seat 81, providing space for the movement of the second clamping block 7. Example 2

Figure 1-4 As shown, it includes a device base 1, an electric push rod 2, a lifting platform 3, a positioning base 4, a V-shaped clamp 5, an adjustment unit 6, a second clamp 7, and a control unit 8;

[0049] The electric push rod 2 is mounted on the equipment base 1;

[0050] The lifting platform 3 is located at the output end of the electric push rod 2, and the lifting platform 3 is equipped with a bearing pressure ring 31.

[0051] The positioning base 4 is set on the equipment base 1 and is used to limit the shaft of the rotor assembly;

[0052] V-shaped clamping block 5 is disposed inside the positioning base 4;

[0053] The adjustment unit 6 is mounted on the positioning base 4 and is used to adjust the position of the V-shaped clamp 5;

[0054] The second clamping block 7 is located inside the V-shaped clamping block 5;

[0055] The control unit 8 is mounted on the V-shaped clamp 5 and is used to adjust the position of the second clamp 7.

[0056] The lifting platform 3 is equipped with a lateral support rod 32, which is slidably connected to the equipment base 1. A support sleeve 33 is fixedly connected to the equipment base 1, and the lateral support rod 32 is slidably connected inside the support sleeve 33. The lateral support rod 32 and the support sleeve 33 play a guiding and stabilizing role during the lifting process, preventing the lifting platform 3 from shifting and ensuring the accuracy of the bearing installation.
