Hollow harmonic speed reduction device with deep-groove ball bearing

Abstract

The invention discloses a hollow harmonic speed reduction device with a deep-groove ball bearing. The hollow harmonic speed reduction device comprises a harmonic speed reducer, a hollow input shaft and the deep-groove ball bearing, wherein the hollow input shaft is arranged in the harmonic speed reducer; a bearing fixing component is arranged on the harmonic speed reducer; the deep-groove ball bearing is arranged between the hollow input shaft and the bearing fixing component; the bearing fixing component comprises a bearing support and a bearing pressure plate; and the two ends of the deep-groove ball bearing are fixed through the bearing support and the bearing pressure plate respectively. According to the hollow harmonic speed reduction device with the deep-groove ball bearing, the deep-groove ball bearing is fixed on the harmonic speed reducer through the bearing fixing component, so that the integral fastness and stability of the harmonic speed reducer are ensured, the using requirements can be met without excessive calibration during application and installation, the installation time is saved, and later equipment examination, repair and maintenance are facilitated.

Description

technical field [0001] The invention relates to a harmonic deceleration device, in particular to a hollow harmonic deceleration device with a deep groove ball bearing, which has a stable structure and is easy to install. Background technique [0002] Due to the structure or special requirements in the application, the harmonic reducer needs to pass through the middle of the reducer or pass through other parts, so the input shaft of the reducer needs to be hollow, and it needs to be driven by a synchronous pulley during installation. In some cases, the input shaft of the reducer needs to be installed with a set of deep groove ball bearings to support the input shaft to ensure the stability of the input shaft, which makes the assembly of the harmonic reducer more complicated and cumbersome, and the installation requirements for parts are relatively high. High, it is not convenient for the adjustment and maintenance of the equipment in the later stage. Contents of the inventi...
