Four-head planetary contra-rotating grinding head

Abstract

The invention discloses a four-head planetary contra-rotating grinding head. Each grinding head box is formed by meshing a main transmission gear, four transition gears, a sun gear, two planetary gears and four transmission gears with one another, wherein two transmission gear shafts are provided with two planetary gears. The main transmission gear drives the transmission gears to rotate (autorotate) to drive the planetary gears to rotate around the sun gear, so that the planetary motion (revolution of the grinding head) is realized. Two main transmission systems are meshed with each other by gears to synchronously contra-rotate. The four-head planetary contra-rotating grinding head has the advantages of large working expansion degree, contra-rotating motion of two grinding heads, mutual cancellation of traction forces from the grinding heads during the operation, easiness, convenience, flexibility, high working efficiency, wide application range, long service life, improvement on grinding and polishing quality and the like.

Description

technical field [0001] The invention relates to a stone grinding device, in particular to a four-head planetary counter-rotating grinding head. Background technique [0002] At present, the mobile floor grinders on the market can be roughly divided into the following types: single-disc machine, double-head machine, and three-head machine. The mechanical efficiency of a single disc is low, and it is difficult to achieve the expected effect. The grinding force of the double-head machine is difficult to meet the needs of hard ground and large-area construction. The traction force of the three-head machine revolution and rotation cannot be completely offset, which will lead to difficulties in mechanical operation. Increase labor intensity. With the development of my country's stone / floor industry and the rapid popularization of the industry's culture, the stone / floor care industry is becoming more and more prosperous today. The traditional labor-intensive operation methods are ...

Problems solved by technology

The mechanical efficiency of a single disc is low, and it is difficult to achieve the expected effect. The grinding force of the double-head machine is difficult to meet the needs of hard ground and large-area construction. The traction force of the three-head machine revolution and rotation cannot be completely offset, which will lead to difficulties in mechanical operation. increase labor intensity

With the development of my country's stone / floor industry and the rapid popularization of the industry's culture, the stone / floor care industry is becoming more and more prosperous. Today, the traditional labor-intensive operation methods are no longer suitable for the development of the stone / floor care industry.
