Abstract

The invention provides a drive gear assembly capable of locating by fine adjustment. The drive gear assembly comprises a driving gear, a driving shaft, a driven gear and a driven shaft, wherein the driving shaft is coaxially fixed and matched with the driving gear, the driven shaft is coaxially fixed and matched with the driven gear, and the driving gear is meshed with the driven gear. The drive gear assembly is characterized in that the driven gear is provided with an adjustment device for adjusting the relative position of working parts arranged on the driving shaft and the driven shaft; and the adjustment device comprises an external coupling sleeve, an adjustment column for adjusting the external coupling sleeve, and a driven inner expansion sleeve, wherein the driven shaft is externally sheathed by the driven inner expansion sleeve, the driven inner expansion sleeve is externally sheathed with the external coupling sleeve and is fixedly matched with the external coupling sleeve, the external coupling sleeve is fixedly arranged on the driven gear, and the adjustment column is arranged on the external coupling sleeve. The drive gear assembly provided by the invention can realize the accurate adjustment on the locating of working parts on transmission shafts by adjustment of the adjustment column, so that the adjustment accuracy can be ensured.

Description

technical field [0001] The invention relates to a transmission assembly in the mechanical field, in particular to a transmission gear assembly capable of fine-tuning and positioning. Background technique [0002] Gear transmission is a mechanical transmission that uses the teeth of two gears to mesh with each other to transmit power and motion. It has the characteristics of compact structure, high efficiency and long life; due to the accurate transmission ratio of the gear transmission, the gear transmission mechanism is often used in some occasions with high mutual cooperation precision. At this time, the initial position of the transmission needs to be accurately positioned to achieve Precise delivery of the entire movement. The existing gear transmission initial positioning mechanism generally uses precision positioning holes to ensure the positioning accuracy of the gears, but this method has the following disadvantages. First, the precision positioning holes are diffic...
