Cone Pendulum Reducer with Small Tooth Difference

Abstract

The invention relates to a conical pendulum type few tooth difference speed reduction device. The conical pendulum type few tooth difference speed reduction device is characterized in that an output disc with a tooth ring on the inner side is arranged on one side of a machine shell through a bearing, the other side of the machine shell is provided with a fixing tooth ring and connected with a connection base, a tooth-ring gear is arranged in the fixing tooth ring, and an oscillating zero tooth difference gear coupler is formed by the tooth-ring gear and the fixing tooth ring; an input bent axle is arranged in the center of the machine shell, the two ends of the input bent axle transversely penetrate the machine shell and are borne by a center bearing of the output disc and a center bearing of the connecting base, and an eccentric shaft of the input bent axle is provided with an oscillating duplex gear through a self-aligning roller bearing; and one end of the duplex gear is engaged with a tooth ring of the tooth-ring gear to form a few tooth difference planetary transmission gear pair, and the other end of the duplex gear is matched with the tooth ring of the output disc to form an oscillating zero tooth difference gear coupler. The conical pendulum type few tooth difference speed reduction device is simple in structure, large in transmission ratio, small in size, small in weight, high in performance cost ratio and long in service life.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, and in particular relates to a conical pendulum type reduction gear with few tooth differences. technical background [0002] The reducer is a very widely used mechanical transmission device. In the prior art, there are many types of planetary transmission devices with large transmission ratios, which have a wide range of applications and good effects. However, the common problems existing in the existing large transmission ratio transmission devices are that the structure is relatively complicated, the processing precision is high, the difficulty is high, and the cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a conical pendulum type reduction gear with less tooth difference, which is not only simple and compact in structure, easy to process, low in production cost, but also large in transmission ratio ...
