Built-in limiting device for slewing bearing and capable of adjusting angle range and application of built-in limiting device

Abstract

The invention relates to a built-in limiting device for a slewing bearing and capable of adjusting an angle range and application of the built-in limiting device, and belongs to the technical field ofautomatic motor limiting. The built-in limiting device is arranged on the outer side of a motor output end of the slewing bearing and comprises an eccentric wheel, a limiting switch, a stirring gear,a lower balance wheel and an upper balance wheel, wherein holes are formed in the centers of the stirring gear, the lower balance wheel and the upper balance wheel; the built-in limiting device is arranged in a main shell, the main shell is fixed to an end cover of the slewing bearing, and the limiting switch is fixed into a bulge of the main shell; an input shaft core exposes the end part afterpenetrating through the eccentric wheel, the stirring gear, the lower balance wheel and the upper balance wheel, and fixation is carried out by using blocking pieces and shaft core screws; and trapezoidal bulges are separately arranged on the side surfaces of the upper balance wheel and the lower balance wheel, and two trigger points separately corresponding to the upper balance wheel and the lower balance wheel are arranged at the positions, facing the center side of the shell, of the limiting switch. The built-in limiting device is arranged relying on the slewing bearing, is integrally wrapped in the shell, the limiting angle range is adjustable, and the structure is reasonable and practical.

Description

technical field [0001] The invention relates to the technical field of motor automatic limit, in particular to a built-in limit device for the adjustable angle range of a slewing support 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 stations generally use slewing bearings, which have excellent performance, good weather resistance, and low price, and are widely used in tracking power stations. Manufacturers of all ages. But problems also follow. Since the environment of the tracking bracket is in the wild and the Gobi wilderness, the environmental test it faces is also quite harsh; because the driving parts of the tracking power station need to drive the battery panels to track the sun through their own rotation, so A contact switch should be installed at both ends of the 90 or 24...

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.
