Gear ring structure of speed reducer

Abstract

The invention discloses a gear ring structure of a speed reducer. The gear ring structure comprises a speed reduction gear ring and a speed reduction gear ring cover matched with the speed reduction gear ring, a planet carrier and a solar wheel are arranged in the speed reduction gear ring, two ends of the inside of the speed reduction gear ring cover are respectively provided with transverse annular sealing cavities and longitudinal annular sealing cavities, rubber pads matched with the speed reduction gear ring are arranged at the staggered positions of the transverse annular sealing cavities and the longitudinal annular sealing cavities, springs are arranged in the transverse annular sealing cavities and the longitudinal annular sealing cavities, one ends of the springs are abutted against the speed reduction gear ring, and the other ends of the springs are abutted against the speed reduction gear ring cover. The gear ring structure of the speed reducer has the advantages that the speed reduction gear ring cover is additionally provided with transverse and longitudinal sealing cavities, and the rubber pads are extruded and positioned by the rubber pads, so that even if the rubber pads deform, no gaps are generated between the speed reduction gear ring and the rubber pads, sealing effect is good, no leakage of the lubricating oil is guaranteed, and operation cost of products is low.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a gear ring structure of the speed reducer. Background technique [0002] The reduction ring gear of the reducer is mainly composed of the planetary carrier, the sun gear shaft, the reduction ring gear, the rubber pad, and the reduction ring gear cover. The rubber pad of the existing reducer is generally located between the reduction ring gear and the reduction gear cover. It is relatively soft. During use, the rubber pad will soften and deform when it encounters lubricating oil, causing a gap between the rubber pad and the deceleration ring gear, resulting in leakage of lubricating oil. The planetary gear will not run smoothly due to lack of lubrication, and even Damage occurs, maintenance frequency increases, and the amount of lubricating oil also increases, increasing the operating burden of the product.
