Novel power head structure

Abstract

The invention provides a novel power head structure which comprises a shell, a driving shaft arranged in the shell and a plurality of driven sets. The driving shaft is sleeved with a plurality of first spiral arc gears, gear hubs of the first spiral arc gears are sleeved with first bearings, and each driven set comprises a second spiral arc gear, a driven shaft and a second bearing, wherein the second spiral arc gear is connected to one end of the driven shaft in a sleeving manner, the second bearing is matched with the second spiral arc gear to be arranged on a gear hub of the second spiral arc gear in a sleeving manner, and the second spiral arc gear coincides with the corresponding first spiral arc gear; and when the driving shaft moves, the first spiral arc gears drive the second spiral arc gears to move to further drive the driven shafts to move, the shell is provided with a first hollow cavity, a second hollow cavity and a tool apron, the first hollow cavity and the second hollowcavity are arranged on the two side faces of the shell, and the first hollow cavity is provided with a sealing cover and a through water way. The product is simple and durable in structure.

Description

technical field [0001] The invention relates to a novel power head structure. Background technique [0002] In the traditional power head, the bearing on the driving shaft is arranged behind the spiral arc gear, so that the length of the driving shaft is longer, and the distance between the bearing and the spiral arc gear is relatively long, so that the rigidity and stability of the driving shaft are insufficient. On the moving group, the distance between the spiral arc gear and the bearing is relatively long, so that the force fulcrum on the driven shaft is far away from the spiral arc gear, so that the rigidity of the driven shaft is insufficient, and it is easy to vibrate during operation, resulting in noise, increased friction and Generate high heat, shorten the life of the product, and there are few types of cutting tools, and the processing is single. Contents of the invention [0003] The present invention is a new type of power head structure, which adopts bearing...
