Built-in limit device for adjustable angle range of slewing bearing and its application

Abstract

The invention relates to a built-in limiting device for an adjustable angle range of a slewing bearing and its application, and belongs to the technical field of automatic motor limiting. and the toggle gear with the central hole, the lower balance wheel and the upper balance wheel, the built-in limit device is arranged in the main casing, the main casing is fixed on the end cover of the slewing bearing, and the limit switch is fixed on the protrusion of the main casing In the middle, the input shaft core passes through the eccentric wheel, the toggle gear, the lower balance wheel and the upper balance wheel, and the end is exposed, and is fixed with a baffle plate and a shaft core screw. The sides of the upper balance wheel and the lower balance wheel are respectively provided with trapezoidal protrusions and the limit switch is provided with two trigger ends corresponding to the upper balance wheel and the lower balance wheel respectively toward the center side of the housing. The built-in limiting device designed in the present invention is arranged on the basis of the slewing bearing, and is integrally wrapped in the casing, and the angular range of the limiting is adjustable, and the structure is reasonable and practical.

Description

technical field [0001] The invention relates to the technical field of automatic motor limiting, in particular to a built-in limiting device for an adjustable angle range of a slewing bearing and its application. Background technique [0002] Today, when photovoltaic tracking technology is widely used, many photovoltaic tracking products have entered thousands of households, and the driving components of photovoltaic tracking power plants generally use slewing bearings, which have excellent performance, good weather resistance and low price, and are widely used in tracking power plants. favored by manufacturers. However, problems also follow. Since the environment where the tracking bracket is located is in the wild and the Gobi wilderness, the environmental test it faces is also quite harsh; because the driving components of the tracking power station need to rotate themselves to drive the panels to track the sun, so A contact switch should be installed at the beginning an...

Problems solved by technology

However, the installation form of this kind of limit is too cumbersome, and the position of the limit and the stopper must be adjusted on site according to the installation factors of the project; and the limit is installed outside, and it is eroded by natural environments such as outdoor exposure, rain, and freezing. In this case, the service life cannot meet the design requirement of 25 years for the overall service life of the equipment.
