Problems solved by technology
[0002] At present, domestic slewing bearings, especially wind power turntable bearing assembly and testing equipment, are mostly simple assembly machines and testing machines manufactured by manufacturers themselves, which cannot meet the mass production requirements of the market.
First of all, at present, it is relatively difficult to select and match steel balls at one time. Most of the steel balls selected by each production unit are selected multiple times based on experience, which is low in efficiency and poor in accuracy; secondly, it is impossible to evaluate the quality and performance of bearings in detail and accurately.

Embodiment Construction
[0023] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0024] Such as figure 1 , figure 2 As shown, the torque measuring device 8 is installed between the driving device 9 and the rotating arm 7, the bearing outer ring 4 is fixed during use, the clamping device 5 positions the bearing outer ring 4, and the bearing inner ring 2 is supported by the hydraulic rotatable support device 6 The support is centered, an appropriate amount of standard steel balls 3 are put in, and the driving device 9 drives the rotating arm 7 to rotate, driving the bearing inner ring 2 to rotate. The torque measuring device 8 measures the torque when the bearing is started and the torque during smooth operation. The thrust hydraulic device 10 c...

The invention relates to an assembly and detection all-in-one machine of a rotating support and a detecting method thereof. A driving device is connected with the input end of a right-angle reducer through an elastic coupling, wherein the reducer is fixed on a workbench base, the output end of the reducer is connected with one end of a moment measuring device through a membrane-type coupling, theother end of the moment measuring device is connected with a rotating shaft through a flat key, the rotating shaft and a rotating arm are connected through a bolt, and a pin hole is arranged at the tail end of the rotating arm; a positioning pin and a clamping device are arranged on a workbench; and a hydraulic rotatable support device and a hydraulic thrust device are fixed on the workbench, wherein the hydraulic rotatable support device comprises an oil cylinder, a roller bearing is arranged on a piston rod of the oil cylinder, a limit bolt is arranged in the oil cylinder, and the hydraulicthrust device and the hydraulic rotatable support device are arranged on the same circumference. The assembly and detection all-in-one machine can be used for detailedly and accurately measuring the starting moment of the bearing and the moment change when the bearing stably rotates and selecting appropriate steel balls by machining with the measured axial internal clearance so that the selectivepairing frequency is greatly reduced.
Description
technical field [0001] The invention belongs to the field of detection equipment, in particular to a slewing bearing assembly and detection integrated machine and a detection method thereof. Background technique [0002] At present, domestic slewing bearings, especially wind power turntable bearing assembly and testing equipment, are mostly simple assembly machines and testing machines manufactured by manufacturers themselves, which can no longer meet the mass production requirements of the market. First of all, at present, it is relatively difficult to select and match steel balls at one time. Most of the steel balls selected by each production unit are selected multiple times based on experience, which is low in efficiency and poor in accuracy; secondly, it is impossible to evaluate the quality and performance of bearings in detail and accurately. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of ...
