Problems solved by technology

[0004] Most of the existing mature turntables are based on the series mechanism. The traditional series mechanism is an open-chain mechanism composed of multiple kinematic pairs connected in series. This mechanism itself has weak bearing capacity, low stiffness, large error, and motion Disadvantages such as high quality and low precision

Abstract

The invention discloses a differential-principle-based two-degree-of-freedom parallel-connection rotating platform. According to the rotating table, a bevel gear A (1) and a bevel gear B (2) are perpendicularly installed through an L-shaped support (4), and outer teeth of the bevel gear A and outer teeth of the bevel gear B are meshed. A load is installed on a disc of the bevel gear A (1) and located at the hollow portion of an inner sleeve (9). Two driving assemblies are symmetrically installed on the two sides of a supporting assembly (5). An outer sleeve (8) and the inner sleeve (9) are installed in the middle of the supporting assembly (5). The outer sleeve (8) is connected to one end of the inner sleeve (9) in a sleeving mode. The two sleeves are provided with ball bearings. According to the rotating platform, rotation and pitching motion of the load can be achieved through a pair of bevel gear mechanisms with the perpendicular axes on the basis of the differential principle. The parallel-connection rotating plate is small in whole size and inertia, high in rotating speed and strong in load capacity and is of the hollow structure.

Description

technical field [0001] The invention relates to a two-degree-of-freedom rotating platform, more particularly, a two-degree-of-freedom parallel rotating platform based on the differential principle. Background technique [0002] A differential mechanism is a mechanism that synthesizes two differential or independent motions into one motion, or decomposes one motion into two differential motions. There are various specific types of differential mechanisms, which can be composed of gears, spirals, chains or steel cables, etc., and are often used in automobiles, tractors, cranes, micrometers and astronomical instruments, etc., to increase force, micro-motion, motion decomposition or synthesis , Error compensation, etc. [0003] The turntable is a complex modern equipment integrating optics, mechanics and electronics, which has important applications in aerospace, aviation, military and manufacturing. The two-degree-of-freedom turntable is one of many turntables, which are wide...
