[0002] Pitch changing is the process of changing the angle of the wind turbine blades, and the pitch changing bearing is the bearing used for the pitch changing mechanism. Like conventional bearings, the pitch changing bearing needs to be internally greased before use to reduce wear during the rotation process. The existing method of adding grease is generally to add grease directly to the roller position inside the bearing, but the bearing is stationary and the grease cannot be added more evenly. If the bearing is not used for a certain period of time, the grease solidifies and cannot be spread quickly and evenly during use, affecting the use effect. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a wind turbine variable pitch bearing grease adding machine with a grease uniforming structure, which solves the problem of directly adding grease to the roller position inside the bearing. However, when the bearing is stationary, the grease cannot be added relatively evenly. If the bearing is not used for a certain period of time, the grease solidifies and cannot be spread quickly and evenly when in use, affecting the use effect.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions: a wind turbine variable pitch bearing greasing machine with a grease uniforming structure, comprising a detection frame, a driving support structure for placing and driving the outer ring of the wind turbine variable pitch bearing to rotate is arranged on the front of the detection frame, and the front of the detection frame is located at a limiting structure for the rotation of the inner ring of the wind turbine variable pitch bearing of the driving support structure, and a grease injection structure for injecting grease into the roller position of the wind turbine variable pitch bearing is arranged inside the detection frame;

[0005] The driving support structure includes a driving wheel and a driven wheel rotatably arranged at the lower left corner and the lower right corner of the front side of the detection frame;

[0006] The grease injection structure includes a peristaltic pump fixedly connected to the inside of the detection frame, a reduction box fixedly connected to the rear side of the detection frame, a servo motor fixedly connected to the input end of the reduction box, and an output end of the reduction box coaxially fixedly connected to the rotating wheel and driving wheel of the peristaltic pump.

[0007] Preferably, a grease injection tube runs through the inside of the peristaltic pump, one end of the grease injection tube passes through the front of the detection frame, and the surface of the detection frame is provided with an adjustment groove for adjusting the position of the grease injection tube output end, and the grease injection tube is made of a plastic metal tube.

[0008] Preferably, the limiting structure comprises an elastic frame penetrating the front wall of the detection frame, and a vertical groove for the elastic frame to slide longitudinally is provided on the front side of the detection frame, and anti-slip protrusions are provided on the upper and lower surfaces of the elastic frame.

[0009] Preferably, convex strips are provided on both sides of the rear end of the elastic frame, vertical plates are fixedly connected inside the detection frame and on both sides of the elastic frame, and limiting grooves are provided inside the vertical plates to slide with the convex strips.

[0010] Preferably, a plurality of rollers are rotatably connected to both left and right sides of the front side of the detection frame.

[0011] Beneficial Effects

[0012] The utility model provides a wind turbine variable pitch bearing greasing machine with a grease-uniform structure. Compared with the prior art, it has the following beneficial effects:

[0013] 1. The fan variable pitch bearing grease adding machine with a grease uniformity structure supports the outer ring of the fan variable pitch bearing and drives it to rotate through the cooperation of the driving wheel and the driven wheel, and a limiting structure is provided to support the outer ring of the fan variable pitch bearing. While the grease injection structure injects grease into the roller, the relative rotation of the inner and outer rings of the fan variable pitch bearing can be used to evenly apply the grease to the roller. On the one hand, the grease can be added quickly and evenly, and on the other hand, the driving wheel is linked with the peristaltic pump to synchronously add grease while driving, and the adding speed is uniform and convenient.

[0014] 2. The wind turbine pitch bearing greasing machine with a grease-uniform structure supports the inner ring of the wind turbine pitch bearing by setting an elastic frame that is elastic and can only be lifted and slid. On the one hand, it can elastically deform to adapt to wind turbine pitch bearings with different inner diameters.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides two technical solutions:

[0021] Figure 1-3 The first embodiment is shown: a wind turbine pitch bearing greasing machine with a grease-uniform structure, comprising a detection frame 1, a driving support structure 2 for placing and driving the outer ring of the wind turbine pitch bearing to rotate is arranged on the front of the detection frame 1, and a limiting structure 3 for the rotation of the inner ring of the wind turbine pitch bearing is located on the front of the detection frame 1. A grease injection structure 4 for injecting grease into the roller position of the wind turbine pitch bearing is arranged inside the detection frame 1, and a plurality of rollers 7 are rotatably connected to both the left and right sides of the front of the detection frame 1;

[0022] The driving support structure 2 includes a driving wheel 21 and a driven wheel 22 which are rotatably arranged at the lower left corner and the lower right corner of the front side of the detection frame 1. The surfaces of the driving wheel 21 and the driven wheel 22 are soft rubber sleeves to increase friction;

[0023] The grease injection structure 4 includes a peristaltic pump 41 fixedly connected to the inside of the detection frame 1, a reduction box 42 is fixedly connected to the rear side of the detection frame 1, a servo motor 43 is fixedly connected to the input end of the reduction box 42, and the output end of the reduction box 42 is coaxially fixedly connected to the rotating wheel and the driving wheel 21 of the peristaltic pump 41, a grease injection tube 44 passes through the inside of the peristaltic pump 41, one end of the grease injection tube 44 passes through the front of the detection frame 1, and an adjustment groove is provided on the surface of the detection frame 1 for adjusting the position of the output end of the grease injection tube 44, and the grease injection tube 44 is made of a plastic metal tube.

[0024] The driving wheel 21 and the driven wheel 22 cooperate to support the outer ring of the fan pitch bearing and drive it to rotate, and a limiting structure 3 is set to support the outer ring of the fan pitch bearing. While the grease injection structure 4 injects grease into the roller, the relative rotation of the inner and outer rings of the fan pitch bearing can be used to evenly apply the grease to the roller. On the one hand, the grease can be added quickly and evenly. On the other hand, the driving wheel 21 is linked with the peristaltic pump 41 to synchronously add grease during driving, and the grease is added at a uniform speed and conveniently.

[0025] Figure 3A second embodiment is also shown, which mainly differs from the first embodiment in that the limiting structure 3 includes an elastic frame 31 that passes through the front wall of the detection frame 1, and a vertical groove 8 is provided on the front side of the detection frame 1 for the elastic frame 31 to slide longitudinally, and anti-slip bumps 33 are provided on the upper and lower surfaces of the elastic frame 31, and convex strips 32 are provided on the left and right sides of the rear end of the elastic frame 31, and vertical plates 5 are fixedly connected inside the detection frame 1 and on both sides of the elastic frame 31, and a limiting groove 6 is provided inside the vertical plate 5 to slide with the convex strip 32.

[0026] An elastic frame 31 which is elastic and can only be lifted and slid is provided to support the inner ring of the wind turbine pitch bearing. On the one hand, it can be elastically deformed to adapt to wind turbine pitch bearings with different inner diameters. On the other hand, the longitudinal sliding method can also adapt to wind turbine pitch bearings with different outer diameters. At the same time, the rotation of the inner ring of the wind turbine pitch bearing can be limited, and the adaptability is strong.

[0027] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0028] When in use, the bearing is sleeved on the outside of the elastic frame 31, and is mounted on the driving wheel 21 and the driven wheel 22. The servo motor 43 is started to drive the peristaltic pump 41 and the driving wheel 21 to operate. The peristaltic pump 41 squeezes the grease injection tube 44 to squeeze the lubricating oil into the bearing. At the same time, the driving wheel 21 drives the outer ring of the bearing to rotate, and the inner ring of the bearing is stationary under the restriction of the elastic frame 31. At this time, the inner and outer rings rotate relative to each other, causing the internal rollers to rotate and spread the grease evenly. The servo motor 43 stops after the operation reaches the set parameters, and then the bearing can be pulled out.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
