[0002] Wind turbine bearings are one of the core components in wind turbine generator sets. They are mainly used to support rotating parts and bear loads transmitted from blades, hubs and other components. Wind turbine bearing tooth jump refers to the up and down jump of the tooth top of the gear or gear ring on the wind turbine bearing relative to the ideal position during rotation. A tooth jump measuring device is required to detect the gear tooth top jump on the wind turbine bearing.

[0016] Working principle: When the device is needed, the technician can place the wind turbine bearing that needs to be measured for tooth jump on the flat position on the lower side of the positioning arc block, and then turn on the hydraulic cylinder fixed on the lower surface of the fixed frame. The output end of the hydraulic cylinder can drive the movable plate to move up and down, and then the movable plate can synchronously drive multiple transmission plates to move through the first support plates at its four ends, and when the transmission plate moves, it can push the guide block to slide on the inner wall of the four ends of the cross slide frame through the second support plate. At this time, the guide block can drive the positioning arc block to slide on the upper surface of the slide rail through the fixed column, so that the internal support positioning of the gear ring can be performed through the positioning arc block to position the gear rings of different sizes, to ensure that the gear ring will not deviate or shake during the measurement process. After that, the technician can adjust the rotary measuring rod, and the second spring rebounds through the suspension plate. The reverse force generated can push the movable plate to move outward, and then push the support rod to slide, thereby driving the rotary measuring rod to fit firmly with the gear ring through the support rod, and then rotating the gear ring. The gear ring can be rotated through the roller fixed by the outer wall of the limit column, reducing the resistance during rotation. At the same time, the gear ring can drive the transmission shaft fixed by the installation sleeve to rotate on the inner wall of the frame through the rotary measuring rod, so as to drive the rotary measuring rods around the suspension plate to fit with the gear ring in turn, and then adjust the dial indicator to contact the outer wall of the rotary measuring rod to measure the tooth jump data of the wind turbine bearing. When the rotary measuring rod needs to be replaced, push the suspension plate upward, and the suspension plate can The block fixed on the outer wall of the mounting column is driven to separate from the inner wall of the slot, and then the hanging plate is rotated ninety degrees and the hanging plate is pulled downward to drive the block to slide out of the inner wall of the through slot, so that the rotary measuring rod can be disassembled. When installing the suitable rotary measuring rod for the measured gear ring, align the block with the position of the through slot and push it upward until the outer wall of the block passes through the inner wall of the through slot, and then the hanging plate is rotated ninety degrees. At this time, the first spring rebounds and the pressure plate can be used to push the block to fit the inner wall of the slot, so that the hanging plate can be installed to ensure the stability of the rotary measuring rod to adapt to gear rings of different specifications. At the same time, to ensure the accuracy of the measurement of the dial indicator, the handle is rotated, and the handle can drive the worm to rotate on the inner wall of the load-bearing frame, and the worm rotates When the gear is moving, it can drive the worm wheel to rotate through the meshing connection, and then the worm wheel can drive the connecting shaft to rotate inside the load-bearing frame, thereby driving the gear to rotate synchronously, and the gear can drive the rack to slide on the inner wall of the load-bearing frame through the meshing connection to adjust the sliding distance of the rack, and can drive the measuring position of the dial indicator to contact the outer wall of the rotary measuring rod to adapt to wind turbine bearings of different sizes and ensure the accuracy of measurement.

Finally, the measuring position of the dial indicator can be adjusted.It expands the applicable range of the measuring device and improves the measuring efficiency and flexibility.

[0017] The present invention provides a tooth runout measuring device for a wind power bearing. It has the following beneficial effects:

[0018] 1. In the present invention, the hydraulic cylinder drives a plurality of transmission plates to move through a moving disk, the transmission plates drive a guiding block to slide, and then drive a positioning arc block to internally support and position the inner diameter of the gear ring through a fixed column, so as to position gear rings of different sizes, ensuring that the gear ring does not shift or shake during the measurement process, thereby achieving the effects of improving the measurement stability and versatility.

[0019] 2. In the present invention, the hanging disk is pushed to drive the block to disengage from the card slot, and then the hanging disk is rotated 90 degrees. It can drive the block to slide out of the through slot to disassemble the rotary measuring rod. At the same time, the block is aligned with the through slot and pushed upward, and then the hanging disk is rotated 90 degrees. The first spring drives the block to fit with the card slot through a pressure disk to install the hanging disk, thereby achieving the installation and replacement of the rotary measuring rod to adapt to gear rings of different specifications and meet the requirements of different measurement accuracies.

[0020] 3. In the present invention, turning the handle drives the worm to rotate, and the worm drives the connecting shaft to rotate through the worm gear. Furthermore, it can drive the gear to rotate synchronously, and the gear drives the rack to slide to adjust the sliding distance of the rack, thereby ensuring that the measuring position of the dial indicator is in contact with the outer wall of the rotary measuring rod, achieving the effect of adjusting the measuring position of the dial indicator, expanding the applicable range of the measuring device, and improving the measuring efficiency and flexibility.
