Embodiment Construction

[0015] refer to figure 1 1. A precision cycloid transmission device for solar heliostats, mainly composed of a pin gear housing (4), a cycloid wheel (7, 16), an output shaft component and a supporting bearing, a pin gear pin (18), and a column pin (5) , column sleeve (6), roller bearings (14, 15), input shaft (12) and support bearings, characterized in that:

[0016] (a) There is an eccentric section P and a threaded section L on the input shaft (12), wherein: the eccentric section P is equipped with a roller bearing (15), and the threaded section L is equipped with an eccentric inner nut (11), and the outer nut (11) is The round fit roller bearing (14), the eccentricity of the eccentric section P and the eccentric inner nut (11) are equal, and there is a spacer (3) between them, forming a double eccentric input shaft with a phase angle close to 180°;

[0017] (b) The tooth profile direction of the cycloid wheel (16) meshing with the needle teeth (18) in the upper half area i...

Abstract

The invention relates to the technical field of speed reduction of solar tracking devices, in particular to a solar heliostat precision cycloid transmission device. The device is characterized in that: (1) the input shaft is provided with an eccentric section P and a thread section L, wherein a roller bearing is matched on the eccentric section P, an eccentric inner nut is arranged on the thread section L, the external circle of the eccentric inner nut is matched with the roller bearing, the eccentricities of the eccentric section P and the eccentric inner nut are equal, and a space ring is arranged between the eccentric section P and the eccentric inner nut so as to form a double-eccentric input shaft; (b) the engaged tooth profile direction of a cycloid gear and needle teeth of the upper half area is opposite to the engaged tooth profile direction of the other cycloid gear and needle teeth of the lower half area, so that the phase angle phi between the eccentric section P and the eccentric inner nut on the input shaft is 180-(0.05-0.15) degrees; and (c) an output shaft with a disk is connected with a uniform loading tray by using 6 to 8 uniformly distributed pins to form a cage-shaped output assembly, and two sides of the cage-shaped output assembly are supported by using a bearing respectively. The device has the advantages of low return difference, high overload capacity, long service life, simple structure and low manufacturing cost.

Description

【Technical field】 [0001] The invention relates to the technical field of deceleration of solar tracking devices, and relates to a precision cycloid transmission device for solar heliostats. 【Background technique】 [0002] Chongqing University's "Precise Cycloidal Pinwheel Planetary Transmission Device" (ZL200810069737) relies on the relative deflection of the two halves of the pinion shells by a small angle to eliminate the hysteresis, and the single-chip wheel does work. The main problem is: the joint surface of the two halves of the needle-tooth housing is prone to oil leakage, and the structure is not compact. [0003] Beihang University "A Transmission Device for Solar Heliostats" (200810104531.X): This invention is a "motor + harmonic reducer + worm gear reducer" structure, and the invention requires "the lowest cost". But the problem is: the price of harmonic reducer is not low. 【Content of invention】 [0004] The purpose of the present invention is to provide a pr...
