Description

Technical Field

[0001] The present invention relates to the technical field of wind power protection components, and particularly relates to a detection device for the production of a planet carrier. Background Art

[0002] The planet carrier is one of the main components of the planetary gear transmission device. The planet gear shafts or bearings are installed on the planet carrier, which is the part that bears the largest external torque in the device. The structural design and manufacturing of the planet carrier have a great impact on the load distribution among the planetary gears, as well as the load-bearing capacity, noise, and vibration of the entire transmission device.

[0003] The existing Chinese patent with the authorized announcement number CN219956488U discloses a planet carrier detection device, including a workbench. A clamping assembly and a detection assembly are provided on the workbench. The clamping mechanism is fixedly connected to the workbench and is used for clamping and fixing the planet carrier. The detection assembly includes a sliding frame and a telescopic rod. The sliding frame is used to drive the telescopic rod to move in the horizontal and vertical directions of the workbench. One end of the telescopic rod close to the workbench is provided with a detection probe. The telescopic rod extends and retracts vertically towards the workbench. The detection probe is used to contact the edge of the pin hole of the planet carrier to obtain data. After the detection probe contacts the edge of the pin hole of the planet carrier, it retracts to the position before contact. After clamping the planet carrier, the aperture of the pin hole can be detected through the detection probe. By comparing the distances between the two contact points on the same straight line, the aperture can be obtained, making the planet carrier put into use more compliant with requirements, thereby reducing the vibration and noise of the transmission device and reducing the damage of the transmission device.

[0004] The deficiencies of the above existing technical solutions are as follows: During the production of offshore wind turbines, after assembling the planetary gears, it is necessary to eliminate the stress between the gears and detect the operation of the gears. The above device is only applicable to the detection of small planet carriers, and there is still room for improvement in terms of practicality. Summary of the Invention

[0005] The purpose of the present invention is to provide a detection device for the production of a planet carrier, so as to solve the problem that the existing technology is only applicable to the detection of small planet carriers and cannot eliminate the stress between the gears and detect the operation of the gears after assembling the planetary gears in a large planet carrier.

[0008] The first drive sprocket and the second drive sprocket are sleeved with a drive chain between them for driving connection. On one end face of the first drive sprocket, a second drive shaft is coaxially and fixedly connected. On the second drive sprocket, a first adjusting shaft is coaxially and fixedly connected. The first adjusting shaft and the second drive shaft are arranged on the same side. Mounting brackets are penetrated and sleeved on both the first adjusting shaft and the second drive shaft. Both the first adjusting shaft and the second drive shaft are rotationally connected to the mounting brackets. On the other end face of the first drive sprocket, a first drive shaft is coaxially and fixedly connected. On the other end face of the second drive sprocket, a second adjusting shaft is coaxially and fixedly connected.

[0009] The mounting plate is fixedly installed on the mounting bracket. The mounting plate is arranged between the first drive sprocket and the second drive sprocket. A first cylinder fixing plate is fixedly connected to the mounting plate. A vertically arranged first adjusting cylinder is fixedly connected to the first cylinder fixing plate. A first cylinder telescopic rod is fixedly connected to the driving end of the first adjusting cylinder. A sprocket fixing frame is fixedly connected to the first cylinder telescopic rod. An adjusting sprocket is rotationally connected to the sprocket fixing frame. The adjusting sprocket abuts against the inner side of the drive chain.

[0010] As a further scheme of the present invention: An adjusting grinding wheel is penetrated and sleeved on the second adjusting shaft and coaxially and fixedly connected. Arc-shaped brake plates are arranged at both ends of the adjusting grinding wheel.

[0011] As a further scheme of the present invention: A fixing plate is rotationally connected to the second adjusting shaft. A fixing rod is fixedly connected to the fixing plate.

[0012] As a further scheme of the present invention: Second cylinder fixing plates are symmetrically arranged and fixedly connected to the fixing plate. A second adjusting cylinder for driving the arc-shaped brake plate is fixedly connected to the second cylinder fixing plates.

[0013] As a further scheme of the present invention: A second cylinder telescopic rod is fixedly connected to the driving end of the second adjusting cylinder. An adapter block is fixedly connected to the second cylinder telescopic rod. The adapter block is fixedly connected to the arc-shaped brake plate.

[0014] As a further scheme of the present invention: The second drive shaft is rotationally connected to the mounting bracket through a first bearing. The outer ring of the first bearing is embedded and fixedly connected to the mounting bracket. The second drive shaft is sleeved and fixedly connected to the inner ring of the first bearing.

[0015] As a further scheme of the present invention: The first adjusting shaft is rotationally connected to the mounting bracket through a second bearing. The outer ring of the second bearing is involved and fixedly connected to the mounting bracket. The first adjusting shaft is sleeved and connected to the inner ring of the second bearing.

[0016] As a further scheme of the present invention: The second adjusting shaft is rotationally connected to the fixing plate through a third bearing. The outer ring of the third bearing is embedded and fixedly connected to the fixing plate. The second adjusting shaft is sleeved and fixedly connected to the inner ring of the third bearing.

[0017] The beneficial effects of the present invention:

[0018] 1. When the present invention is in use, a connecting shaft is coaxially and fixedly connected to the second transmission shaft. The connecting shaft is coaxially and fixedly connected to the main shaft of the planet carrier body. After assembling the planetary gears in the planet carrier body, the main shaft of the planet carrier body is connected to the planetary gears.

Since an adjusting grinding wheel is sleeved and fixedly connected to the second adjusting shaft, arc-shaped brake plates for adjusting the adjusting grinding wheel are arranged on both sides of the adjusting grinding wheel. An adjusting cylinder two for adjusting the arc-shaped brake plates is arranged on the fixing plate. The arc-shaped brake plates are driven by the adjusting cylinder two to intermittently contact the adjusting grinding wheel, thereby causing a certain small-amplitude vibration, which is beneficial to eliminating the stress between the planetary gears on the planet carrier body;

[0019] 2. Since a transmission chain is sleeved between the first transmission sprocket and the second transmission sprocket in the present invention, the kinetic energy on the main shaft of the fan can be transmitted from the first transmission sprocket to the second transmission sprocket. Since an adjusting sprocket and an adjusting cylinder one for controlling the adjusting sprocket are arranged between the first transmission sprocket and the second transmission sprocket, the tension degree of the transmission chain sleeved on the first transmission sprocket and the second transmission sprocket can be controlled by the adjusting cylinder one. By arranging the adjusting cylinder one and the adjusting sprocket, the vibration amplitude of the whole device can be controlled, which is beneficial to ensuring the reliability during the use of the device.
