Harmonic reducer with short barrel-shaped flexible wheel

Abstract

The invention provides a harmonic reducer with a short barrel-shaped flexible wheel. A wave generator is arranged in an inner hole of the flexible wheel (18), and outer teeth of the flexible wheel (18) are engaged with inner teeth of a rigid wheel (6); the rigid wheel (6) is fixedly connected to a spigot inner hole of a housing (16) through a pin (8), a spring gasket (19) and a bolt (20); the flexible wheel (18) and a low-speed shaft (15) are fixedly connected together through a bolt (10) and a spring gasket (11); the wave generator and a high-speed shaft (1) are fixedly connected together through a key (9), and are axially positioned through a shaft elastic retainer ring (3); finally, a bearing (2) and a bearing (12) are arranged at the two ends of the high-speed shaft (1) respectively, so that the wave generator realizes axial positioning motion and radial positioning motion; the high-speed shaft (1) and the low-speed shaft (15) realize linear coaxial transmission. The harmonic reducer disclosed by the invention is reduced in size and weight, and can be used for realizing relatively large torque transmission output.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission and relates to a drive device, in particular to a short tube flexible wheel harmonic reducer. Background technique [0002] Ordinary harmonic reducers are used in technical fields such as aerospace, aviation, radar positioning, satellites, and solar panel drive deployment mechanisms. It can accurately achieve predetermined operation, positioning, control and other use requirements and performance requirements. However, ordinary harmonic reducers also have the problem that their use is limited by the application of the objective space environment. For example, ordinary harmonic reducers are difficult to meet specific use requirements and performance requirements in a small or limited space. In the current state of the art, ordinary harmonic reducers have a large demand for space, and the ratio of the arm length to the inner hole is also large, usually 0.8-0.9, which cannot be used i...

However, ordinary harmonic reducers also have the problem that their use is limited by the objective space environment. For example, it is difficult for ordinary harmonic reducers to meet specific use requirements and performance requirements in a small or limited space.

In the current state of the art, ordinary harmonic reducers have a large demand for space, and the ratio of the arm length to the inner hole is also large, usually 0.8-0.9, which cannot be used in a small and limited space.
