Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wind generator bearing assembly, in particular to an adjustable test bracket for assembling a semi-direct drive generator bearing. Background Art
[0002] With the vigorous development of the wind power industry, the current requirements for bearing assembly technology in the manufacturing process of semi-direct-drive generators are more stringent. The quality of the semi-direct-drive generator bearing assembly is directly related to whether the semi-direct-drive generator can operate well. After the semi-direct-drive generator bearing is assembled, an oil flow test is required. During the test, the bearing assembly must be placed horizontally along the axis. The traditional method of placing the semi-direct-drive wind turbine bearing assembly is to place the bearing assembly directly on the ground, with only wooden pads used for support. However, this placement method is not only inconvenient for oil flow inspection and observation, but also easy to contaminate the bearing oil circuit, is not convenient for lubricating oil collection, has poor structural stability, and poor versatility. Summary of the invention
[0003] In order to solve the problems that the traditional placement method of semi-direct drive generator bearing assembly is inconvenient for oil detection and observation, easy to pollute the bearing oil circuit, and has poor versatility, the utility model provides a new adjustable test bracket for semi-direct drive generator bearing assembly.
[0004] The utility model is realized by adopting the following technical solutions:
[0005] The cam is a vertical support rod, and the cam is a vertical support rod with two guide wheels, each of which is connected to the support wheel to form a vertical support rod.
[0006] Principle description: Two fixed plates and the vertical rod form a support groove, and the support plate can be removably inserted into the support groove. The two vertical brackets at the front are tightly matched with the outer circumference of the large end of the bearing assembly, and the two vertical brackets at the rear are tightly matched with the outer circumference of the small end of the bearing assembly. When this structure is used to place bearing assemblies of different specifications, the placement requirements of bearing assemblies of different specifications can be met by quickly replacing the support plates, so as to improve the versatility of the test bracket.
[0007] Furthermore, one end surface of the support plate close to another group of vertical brackets is an arc surface to improve the overall stability of the test bracket.
[0008] Furthermore, an oblique support rod is fixed between a side surface of the vertical rod away from the corresponding middle horizontal rod and the base to improve the overall strength of the test bracket.
[0009] Furthermore, a connecting rod is fixed between two vertical rods in the same group of vertical brackets to further improve the overall strength of the test bracket.
[0010] Furthermore, the base includes a bottom platform and a height adjustment component for adjusting the height of the bottom platform (it is well known to those skilled in the art that the height adjustment component can be a retractable mechanism, etc., or it can be a height adjustment achieved by a screw structure in the specific method described below), and the structure is more stable.
[0011] Furthermore, there are four groups of height adjustment components distributed at the four corners of the bottom platform. Each height adjustment component includes a chassis, a screw, an upper nut, and a lower nut. The bottom end of the screw is fixed to the chassis. A through hole matching the screw is provided on the bottom platform. The top end of the screw passes through the lower nut, the through hole, and the upper nut in sequence. The upper nut is tightened on the upper part of the bottom platform, and the lower nut is tightened on the lower part of the bottom platform. When the ground is uneven, the horizontal placement of the bottom platform can be achieved by adjusting the height of the screw relative to the bottom platform, thereby achieving the horizontal placement of the bearing assembly to complete the test detection of the bearing assembly. At the same time, the structure is also convenient for replacing a screw with a stronger load-bearing capacity according to the weight of the bearing assembly, further improving the versatility of the test bracket.
[0012] Furthermore, the support plates are made of non-metallic materials to prevent collision with the bearing assembly. In this specific implementation, the support plates are made of nylon material.
[0013] The beneficial effects produced by the utility model are as follows: the placement of bearing assemblies of different specifications is met through the structure of the detachable and replaceable support plate, so as to improve the versatility of the test bracket; the placement level of the test bracket is ensured through the height adjustment component, so as to further improve the versatility of the test bracket; the test bracket has a simple structure and low cost.
