Problems solved by technology

[0003] In order to achieve the effect of prolonging life and reducing wear, there are different lubrication designs in the prior art. For example, the US7,905,326 patent case mainly allows lubricating oil to be injected into the oil supply of the flexible outer tooth cup through the oil supply path of the rigid inner gear ring In the hole, the wave generator can obtain the lubricating effect, but because the flexible outer tooth cup will continuously produce elastic deformation during the operation process, so the ...

Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0031] Please see first figure 1 and figure 2 , The spiral lubricated harmonic reducer 10 of the first embodiment of the present invention includes a rigid inner gear ring 20 , a flexible outer tooth cup 30 , a wave generator 40 , and a spoiler 50 .

[0032] The flexible outer gear cup 30 is disposed in the rigid inner gear ring 20 and engages with the rigid inner gear ring 20 .

[0033] Such as figure 2 and image 3 As shown, the wave generator 40 has a bearing 41 , an elliptical wheel 42 , and a coupling 43 . The bearing 41 is located in the flexible outer gear cup 30 and has an inner ring 44 and an outer ring 45 surrounding the inner ring 44; the oval wheel 42 is located in the inner ring 44 of the bearing 41; th...

Abstract

The invention discloses a helical lubrication type harmonic wave reducer. The helical lubrication type harmonic wave reducer comprises a rigid inner gear ring, a flexible outer gear cup, a wave generator and a flow turbulence component. The flexible outer gear cup is engaged with the rigid inner gear ring. The wave generator is provided with a bearing, an oval wheel and a coupling, wherein the bearing is arranged in the flexible outer gear cup; the oval wheel is arranged in the bearing; and the coupling is connected with the oval wheel. The flow turbulence component is located in an oil storage space formed between the wave generator and the flexible outer gear cup and provided with a rotating shaft portion and a helical blade arranged on the rotating shaft portion. The flow turbulence component is connected with the coupling of the wave generator through a rotating shaft, therefore when the flow turbulence component is driven by the coupling, lubricating oil can be made to generate convection through the helical blade, and thus the bearing of the wave generator can obtain a good lubrication effect.

Description

technical field [0001] The invention relates to a harmonic reducer, in particular to a spiral lubricated harmonic reducer. Background technique [0002] The harmonic reducer is a reduction device with a high reduction ratio. In the existing structural configuration, it mainly includes a rigid inner gear ring, a flexible outer tooth cup set in the rigid inner gear ring, and a rotatable ground The wave generator installed in the flexible external tooth cup, when the wave generator is assembled in the flexible external tooth cup, the flexible external tooth cup will be pushed up by the outer peripheral edge of the wave generator and become elliptical, therefore, When the wave generator is driven by the power source and starts to rotate, the rigid inner gear ring and the flexible outer gear cup can be completely engaged at the long axis of the wave generator, and completely disengaged at the short axis of the wave generator , because there is a difference in the number of teeth...
