Wave gear type hollow rotating platform

Abstract

The invention discloses a wave gear type hollow rotating platform. The wave gear type hollow rotating platform comprises a shell, an output rotating table and a wave gear set; a first installation cavity is formed in the upper end face of the shell in a penetrating mode, and a second installation cavity communicates with the first installation cavity is formed in the side face of the shell; the output rotating table is of a hollow structure and is rotatably mounted in the first installation cavity; the wave gear set comprises a driven gear and a driving gear. The arc-shaped driven gear and the conical driving gear are adopted in a matched mode to form a wave gear set, transmission of 4-5 conical tooth surfaces meshed with the driven gear can be achieved at the same time, the characteristics of high precision and large bearing torque are achieved due to the fact that the number of the tooth surfaces of the gears meshed at the same time is large, and a hollow device is achieved due to the fact that the diameter of the driven gear is large and a large through hole can be formed in the middle of the driven gear, and due to the fact that the transmission mode is offset 40-degree meshing transmission, a certain self-locking function can be achieved.

Description

technical field [0001] The invention relates to the technology in the field of mechanical equipment, in particular to a hypo-gear type hollow rotary platform. Background technique [0002] In the current CNC indexing devices, robot joints, military radars and automated production lines, etc., a variety of rotary motion occasions usually use direct drive motors DD motors, cam dividers, bevel gear rotary platforms or worm gear reducers. However, there are defects in these methods: firstly, the direct drive motor DD motor has high manufacturing cost, low load torque, and self-locking function; the precision of the cam divider is low, and it cannot be used for arbitrary division of angles, arbitrary positioning, and arbitrary forward and reverse rotation. ;The bevel gear rotary platform has low precision and efficiency, small speed ratio, small load torque, and does not have a self-locking function; the worm gear reducer has low precision and efficiency, and small load torque....
