Mechanical balance input device special for oscillating tooth transmission

Abstract

The invention provides a mechanical balance input device special for oscillating tooth transmission. The mechanical balance input device comprises a driving shaft, a bearing, an oscillating gear, mechanical balance rolling bodies, a shell and the like. According to the mechanical balance input device, the device can adapt to various oscillating tooth transmission configurations, and the mechanicalbalance rolling bodies are arranged between the oscillating gear and the shell, so that the mechanical balance of the whole device can be effectively realized; the mechanical balance rolling bodies are divided into single-degree-of-freedom balance rolling bodies and double-degree-of-freedom balance rolling bodies, and the single-degree-of-freedom balance rolling bodies and the double-degree-of-freedom balance rolling bodies can be flexibly selected according to different application occasions; the oscillating gear is a disc-shaped part, at least one end face of the two end faces is provided with a oscillating tooth meshing pair, the oscillating tooth meshing pair can be a cycloid raceway, a chord raceway, a linear raceway, an oscillating gear groove or a segmented continuous curve racewaywhich is periodically distributed along the circumference and provided with a plurality of waves, and the specific selection mode is determined by the transmission type; and a non-undercut tooth surface raceway, an undercut tooth surface raceway or a combined tooth surface raceway can be adopted as the raceway used for being meshed with the oscillating tooth.

Description

technical field [0001] The invention relates to the technical field of movable tooth transmission, in particular to a special mechanical balance input device for movable tooth transmission. Background technique [0002] The movable tooth transmission technology is the fourth transmission technology that is different from the three traditional transmission technologies of planetary gear transmission, harmonic transmission and RV transmission. Such as push rod movable tooth transmission, roller (steel ball) movable tooth transmission, swing movable tooth transmission, sleeve movable tooth transmission and plane steel ball transmission, etc. [0003] Taking roller (steel ball) movable tooth transmission as an example, there are two common configurations: cycloid steel ball movable tooth transmission and sinusoidal steel ball movable tooth transmission; whether it is cycloidal steel ball movable tooth transmission or sinusoidal steel ball movable tooth transmission In the trans...

Problems solved by technology

[0003] Taking roller (steel ball) movable tooth transmission as an example, there are two common configurations: cycloid steel ball movable tooth transmission and sinusoidal steel ball movable tooth transmission; whether it is cycloidal steel ball movable tooth transmission or sinusoidal steel ball movable tooth transmission Transmission, the driving disc meshing with movable teeth is always arranged eccentrically, which causes the mechanical imbalance of the mechanism itself. When it is used in the reducer, the moment of inertia of the whole machine is relatively large, and the vibration problem is serious under high-speed operation conditions.

[0004] For example, "A Two-Stage Closed Undercut Cycloidal Movable Gear Reducer" proposed by the patent No. 202010012353.9, the existing method of mechanically balancing it is to counterweight or reduce the weight of the driving components, and a dynamic balance experiment is required. Greatly increases the difficulty of processing and application of parts; and another patent, such as "A Centrally Symmetrical Double-Stage Nested Undercut Cycloid Reducer" proposed by the patent number 202010012352.4, although it itself adds a center The symmetrical transmission mechanism achieves dynamic balance, but due to the addition of a mechanism, the volume of the whole machine becomes larger and the manufacturing cost becomes higher
