Description

Technical Field

[0001] The present invention relates to the field of easy-to-assemble bearing structures for lubricating pumps of wind turbine generator sets, and in particular to an easy-to-assemble bearing structure for lubricating pumps of wind turbine generator sets. Background Art

[0002] The main function of the easy-to-assemble bearing structure for wind turbine lubrication pumps is to simplify the assembly process, improve maintenance efficiency and enhance system reliability. By optimizing the installation method and structural design of the bearings (such as split, snap-on or pre-aligned structures), the reliance on professional tools for on-site installation is reduced, and downtime for maintenance is shortened. Its application scenarios are concentrated in the high-load, long-cycle operating environment of wind power lubrication systems, especially in remote areas or offshore wind farms where maintenance conditions are limited. This type of bearing can adapt to the vibration, shock and extreme temperature changes of the lubrication pump, while reducing early failures caused by improper assembly and extending the life of the equipment. Typical designs include lubrication-free seals, modular components, etc., taking into account both corrosion protection and sealing performance, and meeting the core needs of the wind power industry for low maintenance costs and high availability.

[0003] When assembling the bearing structure of the common wind turbine lubrication pump on the market, it is necessary to first install the bearing body on the bearing seat, and then install the bearing seat in the wind turbine lubrication pump to complete the assembly of the bearing structure. Complex screws and other tools are required to fix it. To this end, we propose an easy-to-assemble bearing structure for wind turbine lubrication pumps. Summary of the Invention

[0004] The purpose of the present invention is to solve the defects in the prior art and to propose an easy-to-assemble bearing structure for a lubrication pump of a wind turbine generator set.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An easy-to-assemble bearing structure for a lubrication pump of a wind turbine generator system includes a main body and a bearing seat. Protective mechanisms are provided on both sides of the main body. The protective mechanisms include a first protective plate and a second protective plate. A plurality of first insert plates are equidistantly embedded on the first protective plate. First nuts are provided on the first insert plates.

[0007] A second plug plate is embedded on the second protective plate and located on one side of the first plug plate. A second nut is provided on the second plug plate. Both the first plug plate and the second plug plate are provided with transverse grooves.

Several groups of second slots are opened on both sides of the outer ring of the main body, and two groups of second screws are arranged inside the second slots.

[0009] As a further solution of the present invention: the first plug-in board and the second plug-in board are both inserted into the corresponding first slot and second slot.

[0010] As a further solution of the present invention: the ends of the first screw and the second screw are both arranged to penetrate into the corresponding transverse grooves, and the first nut and the second nut are both threadedly sleeved on the corresponding ends of the first screw and the second screw.

[0011] As a further solution of the present invention: a disassembly and assembly mechanism is provided on the bearing seat, the disassembly and assembly mechanism includes a partition, two groups of slots are provided on the side wall of the bearing seat, an arc groove is provided on the inner side wall of the slot, and a groove connected to the arc groove is provided on the side wall of the bearing seat.

[0012] As a further solution of the present invention: two groups of clamping plates are symmetrically arranged on the outer side wall of the main body, fixing grooves are opened on the clamping plates, and two groups of fixing plates are equidistantly arranged on the inner side wall of the partition.

[0013] As a further solution of the present invention: the card plate is slidably arranged in the arc groove through the card slot, the end of the fixing plate passes through the groove and is arranged inside the fixing groove, and the partition is arranged on one side of the main body through the fixing plate and the groove cooperating with the fixing groove.

[0014] As a further solution of the present invention: the main body is arranged inside the main body through a clamping plate and a clamping groove cooperating with an arc groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. During assembly, align the two sets of clips provided on the outer wall of the bearing main body with the clip grooves provided on the bearing seat, and insert the clips into the corresponding clip grooves, then rotate the bearing main body counterclockwise to rotate the clips to the end of the arc groove, and respectively set the two sets of partitions on both sides of the bearing seat, so that the two sets of fixing plates on the side walls of the partitions respectively pass through the corresponding grooves and are set inside the fixing grooves provided on the clips. At this time, the fixing plates, fixing grooves, grooves and clips together constitute a mortise and tenon structure, so that the fixing plates can fix the position of the clips, thereby completing the assembly by setting the bearing main body inside the bearing seat. Since the existing bearing structure requires the bearing main body 1 to be set on the bearing seat first, and then the bearing seat is installed in the wind turbine lubrication pump, and complex screws and other tools are required to fix it, in this solution, a disassembly and assembly mechanism based on the mortise and tenon structure is provided on the bearing seat, which simplifies the assembly steps of the bearing main body and improves the assembly efficiency.
